Chicago's Sales Tax Just Hit 10.5% - Second Highest in the Nation. Here's What Every Business Selling Into the Area Must Know.

As of August 1, Chicago has the second highest combined sales tax rate in the United States.

Chicago's combined sales tax reached 10.5% on August 1, 2026, as the Northern Illinois Transit Authority sales tax added an additional 0.25 percentage point to sales taxes across Cook, DuPage, Lake, Will, Kane, and McHenry counties. According to the Illinois Policy Institute, this brings Chicago's sales tax to the second-highest in the nation, following only Seattle. Porte Brown

But here's what most businesses don't realize: this isn't just a Chicago story.

The increase affects all of Chicago and five surrounding collar counties: DuPage, Kane, Lake, McHenry, and Will. That's a six-county region of nearly 8 million people — one of the largest metro areas in the country. Every retailer and ecommerce seller with customers anywhere in that footprint needs to have updated their systems two weeks ago. WGN Radio

If you haven't done it yet, this is your article.

What Actually Changed — The Full Story

The rate increase didn't come out of nowhere. It's the result of legislation that has been in the pipeline since late 2025.

Transit funding legislation signed by Governor JB Pritzker last December provided for the 0.25% increase to take effect on August 1 in Cook, DuPage, Kane, Lake, McHenry, and Will counties. The tax hike is projected to generate $478 million a year as part of the $1.5 billion in annual transit funding provided in Senate Bill 2111. Central Illinois Proud

The agency collecting the tax has a new name too. NITA — the Northern Illinois Transit Authority — was created by the Illinois General Assembly to replace the Regional Transportation Authority (RTA). The General Assembly passed PA 104-0457 during the 2025 Fall Veto Session. It was signed into law by Governor JB Pritzker on December 16, 2025. FOX 2

The revenue goes directly to the three major transit agencies serving the Chicago metro area — the Chicago Transit Authority (CTA), Metra commuter rail, and Pace suburban bus.

The Rates Are Different Depending on Where You Sell

This is the detail that's catching the most businesses off guard — and it's the most important compliance distinction in this entire change.

The new NITA occupation and use tax rate is 1.25% for general merchandise in Cook County and 1.50% for qualifying groceries, drugs, and medical appliances in Cook County. For businesses making sales from DuPage, Kane, Lake, McHenry, or Will County locations, the new NITA rate is 1.00% for general merchandise, qualifying groceries, and qualifying drugs and medical appliances. NFIB

In plain terms: Cook County and the five collar counties have different NITA rates. A business that sells from a Cook County location pays more than one selling from a DuPage or Will County location — even though both locations are in the NITA coverage area.

For businesses making sales from a Cook County location, the new NITA occupation and use tax rate is 1.25% for general merchandise and 1.50% for qualifying groceries, drugs, and medical appliances. For businesses making sales from DuPage, Kane, Lake, McHenry, or Will County locations, the new NITA rate is 1.00% for general merchandise, qualifying groceries, and qualifying drugs and medical appliances. The Black Chronicle

This rate difference matters enormously for ecommerce sellers using origin-based tax calculation — and for retailers with locations in multiple counties within the NITA footprint.

What the Combined Rates Look Like Now

Chicago's 10.5% combined rate is the most visible — and the most talked about. But the rate picture across the six-county NITA area is more nuanced.

Chicago sits at 10.5% because it layers the Illinois state rate, Cook County tax, Chicago home rule tax, and now the new 1.25% NITA rate on top of each other. That 10.5% applies to general merchandise purchases in the city proper.

In the collar counties, the combined rate is lower — but still meaningfully higher than it was on July 31. Naperville in DuPage County, Aurora in Kane County, Waukegan in Lake County, and Joliet in Will County all saw their combined rates increase by 0.25 percentage points on August 1.

According to the Daily Herald, the increase means consumers are paying $2.50 more on every $1,000 spent in the region on purchases as of August 1. CJBS Accounting Firm

For businesses, the compliance obligation tracks the delivery address — not the business's location. An ecommerce seller based in California shipping to a Naperville customer owes the Naperville combined rate, which now includes the new NITA component.

The Grocery and Drug Rate — A Separate Calculation

Illinois taxes groceries and drugs at a different rate than general merchandise — and the NITA increase applies differently to these categories too.

In Cook County, the NITA rate on qualifying groceries and qualifying drugs is 1.50% — higher than the 1.25% on general merchandise. In the five collar counties, the NITA rate on qualifying groceries and drugs is the same 1.00% as general merchandise.

For retailers selling food or pharmaceutical products in Cook County specifically, the blended rate on grocery transactions is now higher than it was on July 31 — and the increase is larger than the general merchandise bump.

This applies to many common types of sales, including general merchandise, qualifying groceries, qualifying drugs and medical appliances, titled or registered items, cannabis, and aviation fuel. Weiss CPA

Cannabis retailers in Cook County — already navigating one of the most complex tax environments in the country — have another rate component to incorporate into their calculations.

The Political Reaction — Collar Counties Are Not Happy

The transit funding rationale for the increase is straightforward: Chicago's CTA, Metra, and Pace all need capital investment and operating funding. Senate Bill 2111 provided that funding. The 0.25% sales tax across six counties was the revenue mechanism.

But the political reaction from suburban legislators has been sharp — particularly from representatives whose constituents use the transit system rarely or not at all.

State Rep. Steven Reick, R-Woodstock, said suburban taxpayers are bailing out the Chicago Transit Authority. "We're giving them a lifeline of money that we're not getting anything in return for," Reick said. Central Illinois Proud

In McHenry County, Reick said most regularly-scheduled Pace buses run empty. "If we could work out an intergovernmental agreement with Metra to keep rail service coming out here to McHenry County, I wouldn't have a problem if our county board put a referendum on the ballot to get us out of this thing completely," Reick said.

The border shopping effect is already being discussed. Reick noted that McHenry County is on the border with Wisconsin, suggesting people might make economic choices to drive up to Walworth, Wisconsin to buy gas and other items. Eccezion

This is the same dynamic we've covered all year — from Massachusetts residents crossing into New Hampshire to Indiana's gas tax suspension driving border decisions. When a combined rate hits 10.5%, the calculation for major purchases changes.

What Small Businesses Are Saying

Sara Plocker, owner of local boutique Sara Jane, said: "All we ever do is just keep raising the prices and raising the prices and raising the prices, and doing more, not cutting back on anything, or living within the lane that you should or what we can afford." WGN Radio

The frustration reflects a broader reality for Chicago-area small retailers. Illinois already has the highest average combined sales tax rate in the Midwest at 8.98% statewide. The City of Chicago has layered multiple additional local taxes on top of that — a home rule tax, a Chicago Simplified Municipal Tax, the new NITA rate, and various transaction-specific taxes on restaurants, parking, and hotels.

For retailers already operating on thin margins in one of the country's most competitive urban markets, a 0.25% increase may seem small in isolation. In context — stacked on top of years of incremental increases — it feels like one more weight on an already strained balance sheet.

The Second-Highest-in-the-Nation Context

Chicago's 10.5% combined rate makes it the second-highest sales tax rate in the nation, following only Seattle. Porte Brown

That comparison is worth sitting with. Seattle's high combined rate — driven by Washington State's lack of an income tax and significant local additions — has been a well-documented source of consumer behavior effects, border shopping, and business location decisions for years.

Chicago's rate is now in the same territory. At 10.5%, a consumer buying a $1,000 item in Chicago pays $105 in sales tax. The same item purchased online from an out-of-state seller without nexus in Illinois — while technically subject to use tax — may escape collection entirely if that seller hasn't registered.

The enforcement pressure to close that gap is growing. Illinois's AI-powered audit selection capabilities have improved significantly in 2026. The economic incentive for out-of-state sellers to avoid Illinois registration — which always existed — is now larger than ever. Both dynamics will intensify the compliance environment for registered sellers in the months ahead.

What Ecommerce Sellers Need to Know

The NITA increase is destination-based — it applies where the customer is, not where the seller is.

Whether you operate a storefront, sell online, or deliver products into these counties, reviewing your sales tax setup now can help you avoid collecting the wrong amount of tax and reduce potential compliance issues. Ymaws

For ecommerce sellers with Illinois economic nexus — $100,000 in annual Illinois sales — the August 1 rate change means every delivery to a Cook County, DuPage County, Kane County, Lake County, McHenry County, or Will County address now carries a higher rate than it did on July 31.

If your tax software updates automatically, verify the update happened correctly. If you manage rates manually, update your rate tables for all six affected counties immediately. If you use a marketplace facilitator that collects Illinois taxes on your behalf, verify the platform updated its rates for the affected jurisdictions on August 1.

The Compliance Checklist — What To Do Right Now

Businesses should update their point-of-sale and accounting systems to make sure cash registers, point-of-sale software, accounting software, and any other systems used to calculate sales tax are updated to use the new tax rates beginning August 1, 2026. Continuing to use outdated rates could result in collecting the wrong amount of tax from customers. Illinoisstateauthority

The specific steps:

1. Identify every location and delivery address in the six-county NITA area. The affected counties are Cook, DuPage, Kane, Lake, McHenry, and Will. Any retail location or ecommerce delivery address in these counties needs the updated rate.

2. Apply the correct NITA rate for your county. Cook County businesses apply 1.25% for general merchandise and 1.50% for groceries and drugs. Collar county businesses apply 1.00% for all categories. These rates are not interchangeable.

3. Verify your software updated on August 1. If your business uses a third-party provider to calculate sales tax automatically, contact them to confirm they are aware of the changes and have updated accordingly. Don't assume — verify. Illinoisstateauthority

4. Use the MyTax Illinois Tax Rate Finder. You can look up your local tax rate using the MyTax Illinois Tax Rate Finder to confirm your updated combined sales tax rate for any specific address in the affected area. CJBS Accounting Firm

5. Review your August transactions. If you've been collecting the old rate since August 1, you've been under-collecting. Address the gap immediately — the liability sits with the retailer, not the customer, in most cases.

6. Update your Illinois NITA-period returns. When filing your August Illinois return — due September 22 because September 20 falls on a Sunday — make sure the new NITA rate is reflected in your reported collections for Cook County and collar county transactions separately.

The Broader Illinois Context

This rate change doesn't exist in isolation. August 2026 has been one of the most complex compliance months in Illinois history.

Illinois started August with the back-to-school holiday reducing the state rate on qualifying clothing and school supplies to 1.25% through August 16. Simultaneously, the NITA increase added 0.25% to six counties' base rates from August 1. And the Illinois budget passed June 1 included new taxes on social media, digital assets, fantasy sports, and crypto that are working their way through implementation.

For businesses operating in Illinois — particularly in the Chicago metro area — 2026 has required more active compliance monitoring than any recent year. The rate you were collecting in January is not the rate you should be collecting in August. And the rate you're collecting in August may not be the rate you'll collect in October when Washington D.C.'s 7% rate takes effect and other state-level changes roll through.

The compliance environment is not getting simpler. The businesses that stay ahead of it are the ones that build a process for monitoring rate changes rather than reacting to them after the fact.

Illinois Just Brought Back Its Back-to-School Sales Tax Holiday. Here's What's Different in 2026

Illinois shoppers haven't had a back-to-school sales tax holiday since 2022.

That changes this August.

Illinois Governor JB Pritzker signed SB 3019 — the state's $56 billion budget bill — on June 16, 2026. Among its provisions: a 10-day back-to-school sales tax holiday running August 7 through August 16, 2026.

During that period, qualifying clothing and footwear priced less than $125 are subject to a reduced state sales tax rate of 1.25% — instead of the normal 6.25%.

Four years in the making. Ten days of reduced taxes. And a broader category of qualifying items than most people realize.

Here's everything Illinois shoppers and retailers need to know before August 7.

Why Illinois Hasn't Had This Holiday Since 2022

Illinois's back-to-school sales tax holiday isn't a new concept. The state ran similar holidays in prior years — including 2022, when the reduced 1.25% rate applied to qualifying back-to-school items.

In 2022, Illinois reduced the sales tax rate for back-to-school items from 6.25% to 1.25%. While efforts were made in the Illinois legislature to bring it back, no such sales tax holiday had been included since — until this year.

The holiday's return in 2026 comes as part of a broader budget deal that also included new taxes on social media, digital assets, fantasy sports, and cryptocurrency — all passed in the same June 1 budget bill and signed June 16. The holiday is the consumer-friendly piece of a tax package that otherwise expanded Illinois's revenue base significantly.

What's Actually Tax-Reduced — The Full List

This is where Illinois's 2026 holiday is more expansive than most people realize.

The holiday doesn't just cover clothing and footwear. From August 7 through August 16, 2026, a reduced tax rate of 1.25% applies to clothing with a retail seller price of less than $125 — and also to school supplies, school art supplies, instructional materials, and computer supplies. The Sales Tax People

Breaking that down:

Clothing and footwear — under $125 per item:
Shirts, jeans, dresses, shoes, boots, jackets, coats, uniforms, and similar everyday clothing items. The $125 threshold applies per item — a $124 pair of shoes qualifies, a $126 pair does not.

School supplies:
The standard back-to-school lineup — notebooks, folders, pencils, pens, scissors, calculators, rulers, and similar supplies used for school.

School art supplies:
Paints, brushes, sketchbooks, colored pencils, and similar materials used for art classes.

Instructional materials:
Textbooks, workbooks, reference books, and similar materials used for learning.

Computer supplies:
Items used with computers — mice, keyboards, USB drives, printer paper, and similar accessories.

That's a significantly broader category than most neighboring states. While Texas limits its August 7-9 holiday to clothing under $100 and school supplies under $100, Illinois's 10-day window covers computer supplies and school art supplies that most other states leave out entirely.

What "Reduced Rate" Means — Not Tax-Free

This is the most important distinction Illinois shoppers and retailers need to understand.

Illinois's holiday is not a tax-free period. It's a reduced-rate period.

Qualifying items are subject to a reduced rate of state sales tax of 1.25% instead of the normal 6.25%.

The 5% reduction in state rate translates to real savings — but it's not zero. On a $100 purchase, Illinois shoppers pay $1.25 in state tax instead of $6.25. That's $5 in savings per $100 spent.

And local taxes still apply on top of the reduced state rate. Illinois has some of the most complex local sales tax structures in the country — combined rates ranging from 6.25% to 11% depending on the jurisdiction. The holiday reduces the state portion from 6.25% to 1.25% — but the local layer stays at whatever rate applies to the delivery address.

For a shopper in Chicago — where the combined rate is 10.25% — the holiday brings their total rate on qualifying items to approximately 5.25% (1.25% state + 4% Chicago local). That's still meaningful savings, but not zero.

For retailers, this creates a specific compliance requirement: the system needs to apply the reduced 1.25% state rate on qualifying items while continuing to apply the correct local rate unchanged. Getting either piece wrong — reducing local taxes or failing to reduce the state rate — creates compliance errors.

The 10-Day Window — Why It's Unusually Long

Most state back-to-school holidays run two to three days. Illinois's 2026 holiday runs ten.

According to Governor Pritzker's office, families shopping for school supplies, clothing, computers, and other necessities will benefit from the reduced rate August 7-16.

Ten days is more comparable to Connecticut's Tax-Free Week (August 16-22) than to the standard weekend-only format. The longer window gives Illinois shoppers more flexibility to plan purchases — and gives retailers a longer compliance obligation to manage.

The holiday runs from 12:01 a.m. on Friday, August 7 through the end of Sunday, August 16 — covering two full weekends plus the week in between. That's the peak back-to-school shopping window for most Illinois families.

How Illinois Compares to Neighboring States in August

Illinois isn't the only state with a sales tax holiday the week of August 7. Here's how the regional picture looks:

Iowa — August 7-8. Clothing and footwear under $100. Full exemption (state and local).

Missouri — August 7-9. Clothing under $100, school supplies under $50, computers under $1,500. Full exemption.

Wisconsin — No holiday.

Indiana — No holiday.

Kentucky — No holiday.

Illinois — August 7-16. Clothing and footwear under $125, school supplies, school art supplies, instructional materials, and computer supplies. Reduced rate (1.25% state, local taxes still apply).

The key differences: Illinois has the longest window and covers more categories — but it's a reduced rate, not a full exemption. Iowa and Missouri offer full exemptions for their shorter windows. For shoppers near state borders, the choice between a full exemption in Iowa or Missouri for two to three days versus a reduced rate in Illinois for ten days will depend on what they're buying and how close they are to a border.

For Illinois retailers, the ten-day window means a longer compliance period than most competitors in neighboring states — but also a longer opportunity to capture back-to-school shopping traffic.

The same budget bill that created the sales tax holiday also froze Illinois's annual gas tax increase.

Illinois typically increases its state motor fuel tax annually on July 1. The July 1, 2026 increase — scheduled at 1.3 cents per gallon — was pushed back six months to January 1, 2027 by SB 3019.

For Illinois retailers with delivery fleets or logistics operations, the gas tax freeze is a modest but real operational benefit through the end of 2026. And for consumers, it means the cost of driving to back-to-school sales doesn't increase during the holiday period itself.

What Retailers Need to Do Before August 7

Illinois's back-to-school holiday hasn't run since 2022 — which means some retailers' systems may not have been configured for it in years. Here's what needs to happen before August 7:

1. Update your state rate to 1.25% on qualifying items. Your POS and ecommerce tax engine needs to apply the reduced 1.25% state rate to qualifying clothing, footwear, school supplies, art supplies, instructional materials, and computer supplies during the August 7-16 window. The normal 6.25% state rate still applies to non-qualifying items.

2. Keep local taxes unchanged. The reduced rate applies to the state portion only. Local taxes — city, county, transit district — continue at their normal rates for qualifying items. Illinois's local tax structure is complex, and getting this right requires address-level rate accuracy.

3. Verify the $125 threshold applies per item. The clothing and footwear threshold is $125 per item, not per transaction. A customer buying five $120 shirts pays the reduced rate on all five. A customer buying one $130 jacket pays the full 6.25% state rate.

4. Contact your software vendor now. Illinois's holiday hasn't run since 2022. Some tax software platforms may need manual configuration to apply the reduced rate correctly. Verify with your vendor that the August 7-16 reduced rate is programmed — don't assume it updates automatically.

5. Handle online orders correctly. For ecommerce sellers, the reduced rate applies to orders placed and paid for during the August 7-16 window — even if delivery occurs after August 16. The transaction date determines the applicable rate, not the delivery date.

6. Mandatory participation. All businesses open during the holiday are required to participate and cannot advertise that they'll pay or absorb the sales tax on nonqualifying items. The reduced rate is mandatory for qualifying items — and you cannot use the holiday as a marketing tool for non-qualifying products. The Sales Tax People

The Savings — By the Numbers

The switch from 6.25% to 1.25% state rate represents an 80% reduction in state sales tax on qualifying items. Here's what that looks like for a typical Illinois back-to-school shopping trip:

ItemPriceNormal State Tax (6.25%)Holiday State Tax (1.25%)Savings
Sneakers$110$6.88$1.38$5.50
Jeans$75$4.69$0.94$3.75
School backpack$65$4.06$0.81$3.25
Laptop accessories$85$5.31$1.06$4.25
Art supplies$45$2.81$0.56$2.25
Full back-to-school haul$600$37.50$7.50$30.00

$30 in state tax savings on a $600 back-to-school haul. Add in local tax still applying, and the total savings are somewhat less than a full exemption — but across a ten-day window and a broad category of qualifying items, Illinois's 2026 holiday is genuinely more valuable than the reduced-rate format might initially suggest.

Illinois Just Passed a $56 Billion Budget at 4 a.m. Here's Every New Tax That Affects Your Business

Nobody got much sleep in Springfield last night.

Illinois lawmakers approved a $56 billion state budget in the early morning hours of Monday, June 1, 2026 — passing the spending plan around 4 a.m. after an all-night session that stretched through the weekend. Mass.gov

The budget totals $55.9 billion and is supported by a similar amount of revenue. No Republicans voted for the plan. Numeral

To get it across the finish line, Democrats had to temper their expectations. Many had called for taxes on big corporations and billionaires and for Illinois to untie itself from parts of the federal tax code. Instead, the measure freezes corporate net operating loss and taxes social media companies, digital assets, fantasy sports, tobacco, and sports betting on prediction market websites. Galvix

Here's every new tax that matters — and what businesses need to know right now.

New Tax #1: Social Media Companies

This is the headline — and it's genuinely unprecedented at the state level.

Social media companies would be taxed on a progressive scale starting with platforms with 100,000 to 499,999 users paying 10 cents per month for each user, all the way up to platforms with at least 1 million users paying a $165,000 fee plus 50 cents for each user each month. TaxCloud

The tax is based on the number of users in Illinois — not revenue, not profits, not advertising dollars. Just users.

That structure is intentional. It targets scale. The bigger your Illinois user base, the more you pay — and for platforms with tens of millions of users, the numbers get large fast.

A similar tax in Chicago is already tied up in court. Illinois is proceeding at the state level regardless. Expect immediate legal challenges.

Who's affected: Any social media platform with users in Illinois. That includes the obvious names — Meta, TikTok, X, Snapchat, LinkedIn — but potentially also smaller platforms, community networks, and any app with social features that meets the threshold definition.

The compliance question nobody has answered yet: How do you count "users in Illinois"? IP address? Billing address? Self-reported location? The legislation will need to define this clearly, and until it does, compliance will be ambiguous for platforms with large but geographically distributed user bases.

New Tax #2: Digital Assets (Crypto)

New taxes on digital asset sales are expected to generate $65 million for the state alongside fantasy sports taxes.

Illinois is joining a growing number of states that are treating cryptocurrency transactions as taxable events at the state level. The specifics of the digital asset tax structure — rate, calculation method, applicable transaction types — are still being parsed from the legislation passed overnight.

Who's affected: Businesses and individuals who buy, sell, or exchange digital assets in Illinois. If you operate a crypto exchange, process crypto payments, or manage digital asset portfolios for Illinois clients, this is a new compliance obligation to track closely.

What to watch: Whether the tax applies to exchanges, conversions, or only sales to fiat currency — and whether there are de minimis thresholds for small transactions. These details will determine the practical compliance burden significantly.

New Tax #3: Fantasy Sports — 15% on Operators

The state would create a licensing structure for fantasy sports operators and impose a 15% tax on each business. TaxCloud

Fantasy sports has been in a legal and regulatory gray zone in Illinois for years. The new budget formalizes both the licensing framework and the tax — which means DraftKings, FanDuel, and every other daily fantasy operator doing business with Illinois residents now has a defined obligation.

The 15% rate applies to operators — the platforms — not individual participants. But as with most operator-level taxes, the cost will almost certainly flow through to users in the form of reduced prize pools, higher entry fees, or adjusted payout structures.

Who's affected: Fantasy sports operators doing business in Illinois. If you run a fantasy sports platform or marketplace with Illinois participants, this is a new licensing and tax requirement.

New Tax #4: Prediction Markets and Sports Betting

The budget also taxes sports betting on prediction market websites.

Prediction markets — platforms where users bet on the outcomes of real-world events — have been expanding rapidly. Illinois is now explicitly taxing this activity, creating a new compliance category for an industry that has largely operated without clear state-level tax treatment.

This is a fast-moving regulatory space. Platforms like Kalshi and Polymarket have been growing their user bases aggressively, and state legislatures are scrambling to determine how to tax activity that sits at the intersection of financial speculation, gambling, and information markets.

New Tax #5: Tobacco

The budget includes new taxes on tobacco products as part of its revenue package. Galvix

Illinois already has one of the higher tobacco tax rates in the country. The budget adds to that burden — a reliable revenue move that generates relatively little political opposition in 2026 compared to broader consumption tax proposals.

Who's affected: Tobacco retailers, distributors, and manufacturers operating in Illinois. Wholesale and retail price structures will need to be updated to reflect the new rate.

The Gas Tax Freeze — A Win for Drivers

Buried in the budget is one piece of genuinely good news for Illinois consumers and businesses.

The budget freezes the 1.3-cent gas tax increase that was slated for July 1, pushing it to January. Numeral

Illinois adjusts its motor fuel tax annually based on the consumer price index. The July 1 increase had already been calculated and announced. By freezing it until January, the legislature is giving Illinois drivers a six-month reprieve on what would have been a small but real cost increase.

For businesses with vehicle fleets — delivery companies, logistics operators, construction firms — this freeze matters. It's not a dramatic amount per gallon, but across thousands of fill-ups over six months, it adds up.

The Gas Sales Tax Diversion

There's one more sales tax development in the budget that deserves attention.

The budget calls for transferring $150 million in sales tax revenue from gas to the General Revenue Fund once public transportation is fully funded — opening that revenue up to be spent on any purpose.

This is a structural change in how Illinois allocates gas-related sales tax revenue. Currently, a portion of sales tax collected on gasoline is earmarked for transportation. The budget redirects $150 million of that into the general fund — giving the legislature more flexibility in how the money is spent, but reducing the dedicated transportation funding pool.

Republicans criticized the move, with Rep. Ryan Spain saying: "If you're a driver who is irritated by the high price of gas that you're paying, you should be extra irritated knowing where the funds are going." Quizlet

What This Means for Illinois Businesses

The budget passed at 4 a.m. It's now law. But most of the new tax rates and effective dates are still being extracted from hundreds of pages of legislation passed overnight.

Here's what businesses should be doing right now:

1. Social media platforms and apps — determine whether your Illinois user count crosses any of the progressive thresholds. If it does, understand that a new per-user monthly obligation may apply and watch for the legal challenges that are almost certain to follow.

2. Crypto businesses and exchanges — identify your Illinois-based transactions and begin tracking data that would be needed to calculate a digital asset tax obligation. Watch for the Department of Revenue's implementing guidance.

3. Fantasy sports operators — the licensing requirement is new. If you operate a daily fantasy platform with Illinois participants and aren't currently licensed, that process needs to start immediately.

4. Tobacco retailers and distributors — update your cost structures for the new tax rate as soon as the specific rate is confirmed in the implementing legislation.

5. All Illinois businesses — note the gas tax freeze through January and the General Revenue Fund diversion. Both affect your operating cost picture and your customers' disposable income.

The full picture will become clearer over the next few days as the legislative text is analyzed and the Department of Revenue begins issuing guidance. But the framework is clear: Illinois used its overnight budget session to significantly expand its tax base into digital and social media territory — joining a small but growing group of states that are treating the digital economy as a taxable asset rather than a tax-free zone.

Illinois Sales Tax Rates Are Changing on July 1. Is Your Business Ready?

July 1 is five weeks away.

And if you sell into Illinois — whether from a storefront, a warehouse, or an ecommerce platform — your sales tax rates may be about to change.

Effective July 1, 2026, certain Illinois taxing jurisdictions have imposed a new local sales tax or changed their local sales tax rate on general merchandise sales.

The Illinois Department of Revenue is direct about what businesses need to do: update your cash register and any computer program so that beginning on July 1, 2026, you will collect and pay the correct sales tax. Contact your software vendor if you use software to create your forms. Savant Labs

That's not a suggestion. It's a compliance requirement. And the window to act is now.

What's Actually Changing

Illinois has a layered sales tax structure. The state base rate of 6.25% stays the same on July 1. What's changing is the local layer — the rates imposed by individual cities, counties, business districts, and transit authorities on top of the state base.

The affected local tax types include business district sales tax, county public safety tax, home rule municipal sales tax, Metro-East Mass Transit District sales tax, and non-home rule municipal sales tax. Galvix

That covers a wide range of local jurisdictions — meaning the July 1 changes aren't confined to one part of the state. They're spread across Illinois, affecting sellers in multiple regions simultaneously.

Two counties and 48 other municipal governments in Illinois have already increased rates since January 1, 2026 — with McLean County seeing the largest population-area increase at 1 percentage point. July 1 brings another wave. Numeral

Which Jurisdictions Are Affecte

The Illinois Department of Revenue's official bulletin identifies the specific jurisdictions with rate changes effective July 1. Here's a sample of what's changing:

Home rule or non-home rule sales tax rates are changed in the following jurisdictions: Addison, Anna, Arlington, Bartlett, Blue Island, Bull Valley, Charleston, Colfax, Colona, Cornell, Danvers, Deer Creek, De Pue, Dover, Farmer City, Glen Carbon, Hamel, Harrisburg, Highwood, Hudson, Kenilworth, Knoxville, Ladd, Le Roy, Morton, Mount Carmel, New Athens, Newman, Richmond, Sherman, Sleepy Hollow, South Elgin, Spring Grove, Spring Valley, St. Anne, Tonica, Troy, Westmont, Williamsfield, Wonder Lake, Woodson, and Wyanet.

Sales tax rates in McLean and Whiteside counties are also changing. New business districts starting to charge sales tax include: Bartonville Business Development District No. 1, Janson Ford Business District in Breese, Downtown and Dundee Crossing Business District in East Dundee, Montrose Business District, and Parkway I-280 Business District in Rock Island.

Notable specific changes from the IDOR bulletin include:

Why This Is More Complicated Than It Looks

The rate change bulletin sounds straightforward: check the list, update your rates, done.

In practice, it's more complicated — especially for ecommerce sellers and marketplace facilitators.

Sales made by remote retailers who meet the $100,000 tax remittance threshold are subject to business district sales taxes if the property is shipped or delivered to an address in the business district. Sales made over a marketplace by marketplace facilitators who meet the $100,000 threshold are subject to business district sales tax on sales shipped or delivered to an address in the business district.

That means if you sell online and ship to customers in Illinois — and you've crossed the $100,000 economic nexus threshold — you're responsible for collecting the correct business district rate for every delivery address. Not just the city or county rate. The specific business district rate, if the delivery address falls inside one.

Illinois has hundreds of business districts. Rates vary not just by city but by block. A business district that spans four blocks in one direction but not the other can mean two different tax rates on two orders delivered to addresses a few hundred feet apart.

The Illinois sales and use tax rates range from 6.25% to 11.0%, depending on the location — a spread of nearly 5 percentage points driven entirely by local variation. July 1 widens that variation further.

The Grocery Tax Wrinkle

There's a separate but related July 1 issue for businesses that sell food in Illinois.

The Illinois Department of Revenue will issue a separate bulletin specifically regarding municipal and county rates for Municipal and County Grocery Occupation Taxes that take effect July 1, 2026. Savant Labs

This is the downstream consequence of Illinois eliminating its state grocery tax on January 1, 2026 — a move we covered earlier this year. When the state removed its 1% grocery tax, it simultaneously gave municipalities the option to impose their own 1% local grocery tax. Roughly 600 of Illinois' 1,300+ communities opted in — with many taking effect January 1 and others scheduled for July 1.

If you sell qualifying grocery items in Illinois, you're dealing with two separate rate change events: the general merchandise rate changes covered in the main bulletin, and the grocery-specific changes covered in the forthcoming separate bulletin. Both take effect July 1. Both require system updates. Both require different handling of different product categories.

This is exactly the kind of compliance complexity that causes businesses to under-collect or over-collect — often without realizing it until an audit surfaces the discrepancy years later.

What the IDOR Expects You to Do

The Illinois Department of Revenue is unusually explicit about business obligations in this bulletin. Here's what they require:

1. Update your point-of-sale systems. Every cash register, point-of-sale terminal, and tax calculation tool must reflect the new rates before the first transaction on July 1. Collecting the old rate after a rate change takes effect means under-collecting from customers and under-remitting to the state — a liability that sits with the business, not the customer.

2. Contact your software vendor. IDOR specifically instructs businesses to contact their software vendor if they use software to create their forms. Rate changes don't update automatically in all systems — especially custom-built or legacy point-of-sale platforms. Assume your system needs manual verification unless you know for certain it auto-updates. S

3. Verify every affected delivery address. For ecommerce sellers, "update your rates" is more complex than it sounds. You need to verify whether your customer delivery addresses fall inside any of the affected jurisdictions — including business districts with their own separate rates that may not be obvious from city or ZIP code alone.

4. Report correctly on your returns. If a sale was subject to a sales tax rate different from the current rate, report that sale on Line 8a of Forms ST-1 and ST-2. Note: Line 8a is used only to report sales subject to a different sales tax rate — no other use is permitted. Savant Labs

5. Watch for the grocery bulletin. The separate IDOR bulletin covering grocery occupation tax changes is forthcoming. If you sell food in Illinois, don't assume the general merchandise bulletin covers your full compliance obligation — it doesn't.

This Is the Second Wave of 2026 Illinois Changes

The July 1 changes aren't happening in isolation. Illinois has already been through a significant compliance event this year.

On January 1, 2026, Illinois eliminated its 200-transaction economic nexus threshold — meaning out-of-state sellers now trigger nexus based solely on the $100,000 revenue threshold, with no transaction count safe harbor. That same day, the state grocery tax was eliminated at the state level. Dozens of local jurisdictions changed their rates on January 1 as well.

July 1 is the second wave. Illinois updates its local tax rates twice a year — January 1 and July 1 — which means businesses selling in the state face a biannual compliance review cycle just to stay current.

Tax rates in Illinois are generally updated on January 1 and July 1 each year — a pattern that requires businesses to build a standing process for verifying Illinois rates at each update cycle, not just reacting when a notice arrives. Mass.gov

The Five-Week Window

Five weeks sounds like enough time. For businesses with complex systems, multiple locations, or large ecommerce catalogs — it may not be.

The practical timeline works backward from July 1:

Miss any step and you're either over-collecting from customers — a customer service problem — or under-collecting from them — a tax liability that accrues with interest and penalties.

Illinois Sales Tax Nexus Changed in 2026: What Businesses Need to Know

Illinois just made a major change to its sales tax nexus rules, and many businesses don’t realize how much this impacts them.

Starting in 2026, Illinois removed its 200 transaction threshold, leaving only a $100,000 sales threshold to determine economic nexus.

If you sell into Illinois, this change could affect whether you’re required to collect and remit sales tax.

Here’s what changed, and what your business needs to do next.

What Changed With Illinois Sales Tax Nexus?

Illinois simplified its economic nexus rules by removing the transaction-based threshold.

Before 2026, businesses had nexus in Illinois if they had:

Now, only one rule applies:

If your business exceeds $100,000 in sales into Illinois, you have economic nexus.

The number of transactions no longer matters.

Why This Change Matters for Businesses

This update may seem simple, but it has a big impact depending on how your business operates.

1. High-Volume, Low-Dollar Sellers May Benefit

Businesses that previously exceeded 200 transactions but didn’t reach $100,000 in sales may no longer have nexus in Illinois.

This can reduce compliance requirements for certain eCommerce businesses.

2. High-Ticket Sellers Still Trigger Nexus Quickly

If you sell high-value products or services, you may still reach the $100,000 threshold quickly, even with fewer transactions.

For these businesses, the change does not reduce compliance obligations.

3. Simpler Rules, But Not Necessarily Easier

While removing the transaction threshold simplifies the rule, businesses still need to carefully track revenue by state.

Monitoring when you cross the $100,000 threshold is critical to staying compliant.

What Is Economic Nexus?

Economic nexus is a rule that requires businesses to collect sales tax in a state based on their sales activity, even if they don’t have a physical presence there.

This concept became standard after the 2018 Supreme Court decision in South Dakota v. Wayfair.

Today, nearly every state uses economic nexus thresholds to determine tax obligations for remote sellers.

What Businesses Should Do Now

If you sell into Illinois, it’s important to review your sales activity under the updated rules.

Start by:

Even if this change reduces your obligations, it’s important to confirm your status and avoid potential compliance issues.

Final Thoughts

Illinois’ decision to remove the transaction threshold is part of a broader trend toward simplifying sales tax rules.

However, for businesses operating across multiple states, sales tax compliance is still complex and constantly evolving.

Understanding where you have nexus is the first step to staying compliant.

Chicago Cloud Tax Rises to 15%: What SaaS & Platforms Need to Know

Chicago just raised its cloud tax to 15%.

Let’s break that down.

Starting January 1, Chicago’s Personal Property Lease Transaction Tax increased from 11% to 15% on:

If it’s hosted remotely and used by someone in Chicago, it may now be subject to a 15% city tax.

That’s higher than most state sales tax rates.

And this is not Illinois sales tax.

This is a Chicago municipal tax, administered by the Chicago Department of Finance.

What Is Chicago’s Cloud Tax?

Chicago applies its lease transaction tax to the right to use software remotely.

That means if your customer is located in Chicago and pays to access software in the cloud, the transaction may be taxable at 15%.

This is separate from rules administered by the Illinois Department of Revenue.

Two different authorities. Two different tax systems. One compliance headache.

And Then There’s the Social Media Tax

Chicago also rolled out what’s widely considered the country’s first social media tax.

Here’s how it works:

If your platform collects consumer data from more than 100,000 Chicago users, you owe:

$0.50 per month for every user above that threshold.

Every month.

This means companies now have to:

You’re not just tracking revenue by state anymore.

You’re tracking users by municipality.

Welcome to municipal tax sourcing.

Why This Is a Big Deal for SaaS Companies

Most companies budget for:

Very few budget for:

This is where compliance gaps happen.

And at 15%, under-collection is not a rounding error.

Who Is Most Affected?

This impacts:

If you have customers or users in Chicago, you need to evaluate exposure.

The Real Risk

The biggest issue isn’t the rate.

It’s that most companies don’t know this exists.

Local digital taxes are growing. Cities are getting creative. And enforcement is increasing.

Sales tax compliance is no longer just state-by-state.

It’s state + city + platform thresholds + sourcing rules.

What Should You Do Now?

If you sell SaaS or operate a platform with Chicago users:

✔️ Review whether your service qualifies under the lease transaction tax
✔️ Confirm your billing system applies the 15% Chicago rate correctly
✔️ Evaluate whether you exceed the 100,000-user threshold
✔️ Document how you determine user location
✔️ Review registration and filing requirements with the city

This is the part of sales tax nobody budgets for — until it becomes a problem.

Not Sure If This Applies to You?

If you sell SaaS, AI tools, subscriptions, or operate a data-driven platform and aren’t sure whether Chicago’s 15% cloud tax or social media tax affects you, schedule a free consultation call with our team at sales.tax.

We’ll review your footprint, identify municipal exposure risks, and help you build a compliant strategy before this turns into a costly issue.

Chicago’s Personal Property Lease Transaction Tax Increase

Also effective January 1, 2026, Chicago quietly enacted a year-end rate increase to its Personal Property Lease Transaction Tax, raising the rate from 11% to 15%.

What it can affect:

The change is especially relevant for technology-driven businesses operating in or selling into Chicago. While the update did not come with much fanfare, it has a real impact on ongoing tax collection and filing obligations. Businesses subject to this tax should confirm they are applying the updated rate, and those who file the tax in Chicago should be aware of the change to avoid under-collection or compliance gaps moving forward.

Simplified Economic Nexus in Illinois

As of January 1, 2026, Illinois simplified its economic nexus standard by eliminating the transaction count threshold. Remote sellers will no longer trigger sales tax nexus based on the number of transactions alone. Instead, nexus will be determined solely by annual gross sales into Illinois, aligning the state more closely with a revenue-based approach.

For growing businesses, this change reduces complexity—but it doesn’t eliminate risk. If your Illinois sales exceed the state’s dollar threshold, registration and ongoing compliance are still required. Now is a good time to revisit your nexus footprint, confirm where you’re exposed, and make sure your sales tax strategy keeps pace with your growth.
