Maryland passed the first digital advertising tax in the country in 2021. Since then, at least 13 other states have proposed something similar. None of them have passed it.

That's the honest state of play heading into 2026: one active law, a lot of pending proposals, and a legal battle in Maryland that's far from settled. If your business generates revenue from digital advertising, here's what you actually need to know.

What Is a Digital Advertising Tax?

A digital advertising tax is a state-level tax imposed on gross revenues earned from digital advertising services. Unlike sales tax, which is typically collected from the buyer, these taxes are levied directly on the company earning the ad revenue.

That distinction matters more than it might seem. You can't simply add a line item to an invoice and call it done. The tax burden falls on the platform or seller generating the revenue, which means it affects pricing strategy, margins, and how you structure your services.

The types of advertising typically covered under these proposals include:

  • Display advertising on websites and apps
  • Search engine advertising
  • Social media advertising
  • Programmatic advertising and ad exchanges

The calculation isn't simple either. To comply, you'd need to know how much of your digital advertising revenue is attributable to users in each taxing state, usually determined by where the ad was displayed based on IP address or device location. That's a data infrastructure challenge before it's even a tax compliance challenge.

Maryland: The Only State with an Active Law (and It's Complicated)

Maryland became the first state to enact a digital advertising tax in February 2021, when the legislature overrode Governor Larry Hogan's veto. The tax took effect for the 2022 tax year.

Here's how it works:

Who it applies to: Companies with at least $100 million in global annual gross revenues AND at least $1 million in digital advertising revenue derived from Maryland users.

Rate structure:

  • $100M to $1B in global revenue: 2.5%
  • $1B to $5B: 5%
  • $5B to $15B: 7.5%
  • Over $15B: 10%

What's taxed: Gross revenues from digital advertising delivered to devices with IP addresses located in Maryland.

Those rates are not marginal. Once a company crosses a threshold, that rate applies to their entire Maryland-sourced ad revenue base. A company with $1.5 billion in global revenue pays 5% on all its Maryland digital ad revenue, not just the portion above the $1 billion line.

The original article called Maryland a working blueprint that other states were following. That's not an accurate read of where things stand.

Maryland has collected roughly $90 million per year since the tax took effect, well short of the $250 million annually the state projected. And that revenue may need to be refunded. Multiple lawsuits are still active, challenging the tax on grounds including the Internet Tax Freedom Act, the Commerce Clause, Due Process, and the First Amendment.

The most significant recent development: in August 2025, the U.S. Court of Appeals for the Fourth Circuit ruled that the provision prohibiting companies from telling customers about the tax violates the First Amendment. That provision, which required companies to absorb the tax in silence, was subsequently struck down permanently by the district court in October 2025. The state chose not to appeal.

The tax itself is still in effect, but challenges to its core structure are still pending in the Maryland Tax Court, with cases filed by Apple, Google, Meta, and Peacock TV. Hearings were held in July 2025 and decisions are expected in late 2025 or 2026. If those cases succeed, Maryland may need to issue refunds on everything collected to date.

What other states are watching isn't a success story. It's a cautionary one. Legal scholars and tax policy observers have described Maryland's experience as a warning about the risks of taxing the digital economy without fully accounting for constitutional constraints.

States with Pending Proposals

None of these have passed. All are watching what happens in Maryland before moving forward.

Rhode Island has introduced legislation modeled on Maryland's approach, targeting companies with significant global revenues on digital advertising delivered to Rhode Island users.

Connecticut has been exploring digital advertising taxation as part of broader budget conversations. Proposals have surfaced in multiple legislative sessions.

Indiana introduced a bill with similar provisions targeting major platforms. Legislative hearings have taken place and there has been bipartisan interest, though no final vote.

Arkansas introduced legislation mirroring Maryland's structure, with a focus on revenue from out-of-state technology companies serving Arkansas residents.

Massachusetts has seen proposals in early stages. Given the size of its tech and advertising market, a Massachusetts law would have significant reach, which is part of why it's attracting attention from both supporters and opponents.

Each state is taking a slightly different approach to thresholds, rate structures, and definitions. If any of these pass, compliance won't translate cleanly from one state to the next.

How This Differs from Sales Tax Compliance

If you're already managing multistate sales tax, don't assume digital advertising taxes will plug neatly into your existing processes. They're a different animal.

The tax base is different. Sales tax applies to the transaction price. Digital advertising taxes apply to gross receipts from advertising services, whether or not those services are profitable.

Who pays is different. Sales tax is collected from the buyer and remitted by the seller. Digital advertising taxes are imposed directly on the revenue earner. There's no pass-through by default.

Nexus triggers are different. Sales tax nexus flows from physical presence or economic activity thresholds. Digital advertising tax exposure is determined by where the ad is viewed, based on device location. That's a fundamentally different footprint.

The apportionment challenge is real. Determining how much revenue is sourced to a specific state requires knowing where each ad impression was delivered. If your ad tech stack can't produce that data by state, you have a systems problem before you have a compliance problem.

How to Think About Your Exposure

If your business earns revenue from digital advertising, here's a practical framework for evaluating where you stand.

Start with global revenue. Most proposals use a global revenue floor of $100 million to determine applicability. If you're well below that, current proposals likely don't reach you. But thresholds can change, so don't stop the analysis there entirely.

Calculate your state-level digital advertising revenue. For states with active laws or well-advanced proposals, determine how much of your digital advertising revenue is attributable to users in those states. This requires reliable data on where ads are delivered.

Apply the rate structure. Once you have state-level revenue, apply the applicable rate based on your global revenue tier. Remember the rates aren't marginal.

Factor in compliance costs. The operational cost of tracking, reporting, and filing across multiple states can approach or exceed the actual tax liability, especially in the early stages of a new compliance program.

Document your methodology. However you calculate state-specific apportionment, write it down and apply it consistently. If you're ever examined, you'll need to show your work.

Common Mistakes to Avoid

Treating this like a solved problem. Maryland is the only enacted law, and it's still being litigated. But that doesn't mean you should ignore the issue. Planning for a possible multi-state patchwork now is cheaper than scrambling when a second state passes something.

Assuming your current infrastructure is ready. If your ad tech platform doesn't produce state-level impression or revenue data, that's the first gap to close. Tax compliance depends entirely on having accurate underlying data.

Waiting for full legal clarity. There will be more court decisions. Some provisions may be struck down. But waiting for a final, clean answer is a high-risk strategy when the underlying law is already in effect in at least one state and more proposals are advancing.

Underestimating the pricing implications. Even if the pass-through prohibition in Maryland is now gone following the First Amendment ruling, you still need a pricing strategy. How you absorb or communicate these costs is a business decision, not just a compliance one.

Action Checklist

Assessment

  • Calculate your company's global annual gross revenues
  • Determine your digital advertising revenue by state, or identify where your data gaps are
  • Identify which states' thresholds you currently meet or may meet as you grow
  • Review what geographic reporting your current ad tech stack can produce

Monitoring

  • Build a process for tracking legislative developments in Maryland, Rhode Island, Connecticut, Indiana, Arkansas, and Massachusetts
  • Set quarterly reminders to review state tax updates
  • Know who on your team owns this topic, or identify an outside resource

Data Infrastructure

  • Audit your ability to attribute ad impressions and revenue to user location by state
  • Close any gaps in state-level reporting before compliance deadlines arrive
  • Develop a consistent apportionment methodology and document it

Financial Planning

  • Model your tax exposure under current Maryland law and under scenarios where one or more additional states pass legislation
  • Build digital advertising tax estimates into your budget planning
  • Work through the pricing implications with finance and sales leadership

Compliance Preparation

  • Identify filing deadlines and requirements for states with active laws
  • Determine whether you need outside support for compliance
  • Keep records of your apportionment methodology and calculations

When to Bring in Outside Help

Some businesses can manage this internally. Others will find the combination of legal uncertainty, data requirements, and cross-state variation more than their internal team is set up to handle.

You're probably fine internally if your digital advertising revenue is concentrated in one or two states, your ad tech already produces reliable geographic data, and you have tax professionals on staff with gross receipts tax experience.

You should consider outside support if your digital advertising revenue spans multiple states, your current systems can't easily break out revenue by user location, or you're trying to assess exposure in a state with advancing legislation and aren't sure how the rules would apply to your business.

Digital advertising taxes sit at the intersection of tax law, technology, and data infrastructure. That's not a combination most internal tax teams deal with regularly.

People Also Ask:

What is a digital advertising tax?

A digital advertising tax is a levy imposed on the gross revenues a company earns from digital advertising services within a specific state. Unlike sales tax — which is imposed on the buyer — digital advertising taxes are generally imposed on the provider or seller of the advertising services and are calculated as a percentage of the revenue attributable to users or devices located in the taxing state. The tax is typically applied on a sliding scale based on the company's global annual revenue, meaning larger companies face higher rates. Maryland was the first state to enact a digital advertising tax in 2021, and it remains the primary active model that other states have proposed to replicate or modify.

How does Maryland's digital advertising tax work?

Maryland's Digital Advertising Gross Revenues Tax — commonly called the DAGR tax — applies to companies with over $100 million in global annual revenues that also generate more than $1 million in digital advertising revenues sourced to Maryland. The tax rate is graduated based on global revenue: 2.5% for companies with between $100 million and $1 billion in global revenues, rising to 10% for companies with over $15 billion. The taxable base is determined by an apportionment fraction — Maryland-sourced devices accessing the advertising as a share of total worldwide devices. Companies subject to the DAGR must file quarterly estimated returns and an annual return due April 15. Critically, the tax is imposed on the provider of the advertising services and cannot be passed on to customers as a separate line item — a restriction that has itself been subject to litigation.

Which states have digital advertising taxes in 2026?

Maryland remains the only state with a fully enacted and operational digital advertising gross revenues tax as of 2026. Washington enacted a broader digital services tax in 2025 that includes advertising-related revenues. Utah enacted a targeted advertising tax in 2026 that applies specifically to advertising sold via a bidding process based on individual data profiles. Chicago has a digital advertising ordinance that has faced litigation. Rhode Island proposed a 10% digital advertising tax effective January 1, 2026, but it was removed from the final budget bill. Connecticut, Indiana, Arkansas, and Massachusetts have advanced similar proposals that have not yet passed. The legal and legislative landscape is changing rapidly — states that failed to pass proposals in 2025 are expected to reintroduce them in 2026 legislative sessions.

What counts as digital advertising for tax purposes?

The definition of digital advertising varies by state but generally includes banner advertising, search engine advertising, interstitial advertising, and other comparable advertising services delivered via a digital interface. Maryland's DAGR tax defines digital advertising services broadly to include these categories, while specifically excluding certain types of advertising. The definitional boundaries matter enormously for compliance — programmatic advertising, sponsored content, native advertising, and retargeting campaigns have all been subject to classification questions under various state proposals. Some state proposals have drawn the line differently from Maryland — for example, Utah's 2026 targeted advertising tax applies only to advertising sold via a bidding process based on individual data profiles, which is a narrower definition than Maryland's general digital advertising framework. Companies cannot assume a single definition applies across states.

Can businesses pass the digital advertising tax on to their customers?

Under Maryland's DAGR tax, no. The law explicitly prohibits taxpayers from passing the tax on to customers as a separate fee, surcharge, or line item on an invoice. The entire purchase price of digital advertising services — including any increase designed to recover the DAGR — is subject to the tax. This pass-through prohibition was itself challenged in court and a provision of it was struck down as a First Amendment violation, though the core tax structure remains in place. For businesses that provide digital advertising services, this means the DAGR is a direct cost that must be absorbed into pricing or managed through other means — it cannot be listed on an invoice the way sales tax is. Companies that have been attempting to recover the tax through general rate increases should review whether their approach complies with the current state of the law following the court rulings.

What is the Internet Tax Freedom Act and why does it matter for digital advertising taxes?

The Internet Tax Freedom Act — commonly referred to as the ITFA — is a federal law that prohibits states from imposing discriminatory taxes on electronic commerce and from taxing internet access. It has become one of the central legal arguments used to challenge state digital advertising taxes, including Maryland's DAGR. Opponents of digital ad taxes argue that by targeting revenues derived from internet-based advertising specifically — rather than taxing all advertising equally — states are imposing a discriminatory tax on electronic commerce in violation of the ITFA. These challenges have not yet produced a definitive federal ruling striking down the Maryland tax, and litigation is ongoing. The outcome of the Maryland ITFA challenge is being closely watched by every other state considering a digital advertising tax, because it will significantly shape whether and how future proposals are drafted to withstand legal scrutiny.

What should my business do if we generate revenue from digital advertising?

Start by determining whether your business meets the revenue thresholds that trigger liability in active states. In Maryland, the threshold is over $100 million in global annual revenues and over $1 million in Maryland-sourced digital advertising revenues. In Washington and Utah, different thresholds and definitions apply. If you meet those thresholds, you need to assess your current compliance position — are you tracking device-level apportionment data for Maryland? Are you filing quarterly estimated DAGR returns? For businesses below current thresholds, the priority is monitoring: the legislative landscape is shifting quickly, and several states that failed to pass digital ad tax proposals in 2025 are expected to reintroduce them in 2026. Building a tracking process for state digital advertising tax proposals now — rather than scrambling to assess exposure after a law passes — is significantly less expensive than retroactive compliance.
