What's the Difference Between Sales Tax and Excise Tax?
You've probably paid both without realizing it.
Every time you fill up your gas tank, part of what you pay is an excise tax — baked into the price before you even get to the pump. Every time you check out at a store, the tax added to your total is a sales tax.
Same receipt. Completely different taxes.
Here's how to tell them apart — and why it matters for your business.
The Short Answer
Sales tax is a broad tax applied to most retail purchases. It's calculated as a percentage of the sale price, added at checkout, and collected from the buyer.
Excise tax is a targeted tax applied to specific goods — like fuel, alcohol, tobacco, and airline tickets. It's usually a fixed amount per unit, collected earlier in the supply chain (from manufacturers or wholesalers), and baked into the product's price before it reaches you.
One is wide. The other is surgical.
How Sales Tax Works
Sales tax is what most people think of when they hear "tax at checkout."
It's imposed by state and local governments on the retail sale of most goods and some services. The seller collects it from the buyer at the point of sale, then remits it to the state.
Key characteristics:
- Applied as a percentage of the purchase price
- Visible on your receipt as a separate line item
- Varies by state, county, and city — combined rates can exceed 10% in some areas
- Collected by the seller, paid by the buyer
- 45 states collect a state-level sales tax (Alaska, Delaware, Montana, New Hampshire, and Oregon do not)
If you buy a $500 laptop in a city with a combined 8% sales tax rate, you pay $40 in sales tax on top. The rate is the same whether the laptop costs $500 or $5,000 — the tax scales with the price.
How Excise Tax Works
Excise tax is different in almost every way.
It's imposed on specific goods and services — usually ones with significant social costs or high revenue potential. Think gasoline, cigarettes, alcohol, firearms, and airline tickets.
Key characteristics:
- Applied to specific products only, not general purchases
- Usually a fixed amount per unit (e.g., $0.184 per gallon of gasoline federally)
- Hidden in the product's price — consumers often don't see it as a separate charge
- Collected upstream — at the manufacturer or wholesale level, not at the register
- Exists at both the federal and state level
Common examples of excise taxes in the U.S.:
- Gasoline — $0.184 per gallon (federal), plus additional state taxes
- Cigarettes — federal and state excise taxes stacked on top of each other
- Alcohol — taxed per gallon depending on the type (beer, wine, spirits)
- Airline tickets — 7.5% federal excise tax on the ticket price
- Indoor tanning — 10% federal excise tax
- Firearms and ammunition — 10–11% federal excise tax
Unlike sales tax, excise taxes don't go up automatically when prices go up. If gasoline costs $3 per gallon or $5 per gallon, the federal excise tax is still $0.184 per gallon either way.
The Key Differences Side by Side
| Sales Tax | Excise Tax | |
|---|---|---|
| What it applies to | Most goods and services | Specific products only |
| How it's calculated | % of purchase price | Fixed amount per unit (usually) |
| Who collects it | Seller, from buyer at checkout | Manufacturer or wholesaler |
| Visibility | Shown separately on receipt | Built into the product price |
| Purpose | General government revenue | Revenue + behavior control |
| Level | State and local | Federal and state |
Why Both Can Apply to the Same Product
Here's where it gets interesting — and where businesses can get caught off guard.
Sales tax and excise tax are not mutually exclusive. They can both apply to the same transaction.
When you buy a pack of cigarettes, the manufacturer has already paid federal and state excise taxes on them. That cost is built into the retail price. Then, when you buy them at the store, sales tax is added on top in most states.
You're paying both. Most people never realize it.
The same thing happens with alcohol, gasoline (in some states), and other excise-taxed goods. Businesses selling these products need to understand both their excise tax obligations (paid earlier in the supply chain or remitted separately) and their sales tax obligations (collected from customers at the point of sale).
A Note on Hawaii
Hawaii is a special case worth mentioning.
Instead of a traditional sales tax, Hawaii imposes a General Excise Tax (GET) — a tax on businesses for the privilege of doing business in the state. It applies to virtually all business activity: retail, wholesale, services, rentals, and more.
The rate is generally 4% at the state level, with an additional 0.5% surcharge in Honolulu County. Unlike sales tax, GET is technically a tax on the business, not the buyer — but most businesses pass it on to customers at checkout.
If you sell to customers in Hawaii, GET applies differently than a standard sales tax. It's one of the more commonly misunderstood tax structures in the country.
What This Means for Your Business
If you sell excise-taxable goods — fuel, alcohol, tobacco, firearms, certain beverages — you have obligations beyond standard sales tax compliance. Excise taxes are often filed separately, on different schedules, with different agencies. Missing them is easier than you'd think.
If you sell general goods or services, excise tax likely doesn't apply to you directly — but you should know it exists, because your suppliers may be passing excise costs through to your pricing.
And if you operate in multiple states, the overlap between sales tax and excise tax rules adds another layer of complexity to get right.
