Excise Tax: What It Is, How It Works, and What Businesses Need to Know

Most business owners know about income tax, sales tax, and payroll taxes. But there's another category of tax that catches many entrepreneurs off guard—excise tax. If your business sells fuel, alcohol, tobacco, certain vehicles, or even offers indoor tanning services, you may be responsible for collecting and remitting excise taxes to the IRS.

This guide breaks down what excise tax is, which businesses are affected, how to calculate it, and how to stay compliant.

What Is Excise Tax?

Excise tax is a federal tax imposed on the sale or use of specific goods and services. Unlike a general sales tax that applies broadly to most consumer purchases, excise taxes target particular products—often ones associated with public health concerns, environmental impact, or heavy infrastructure use.

You'll sometimes hear excise taxes called "sin taxes" because they frequently apply to alcohol, tobacco, and gambling. But the category is much broader than that. Businesses dealing in fuel, aviation, heavy trucks, communications equipment, and even vaccines may have excise tax obligations.

A key distinction: excise taxes are typically levied on the producer or seller, not the end consumer. However, businesses routinely pass the cost along to customers by embedding it in the product's price. If you've ever noticed a line on your phone bill labeled "federal excise tax," or seen fuel prices broken down to show taxes per gallon, you've seen excise tax in action.

How Is Excise Tax Different from Sales Tax?

Many people confuse excise tax with sales tax, but they work differently:

	Excise Tax	Sales Tax
Who pays	Businesses selling specific goods	Consumers (collected by businesses)
Scope	Targeted at specific products	Broadly applied to most goods/services
Visibility	Often embedded in product price	Usually shown separately on receipts
Level	Federal (and sometimes state)	State and local

Sales tax is a percentage added at the point of sale on a wide range of transactions. Excise tax is more surgical—it targets specific categories and can be calculated per unit or as a percentage of price.

Common Types of Excise Tax

The IRS administers dozens of excise taxes across different industries. Here are the most common categories businesses encounter:

Fuel and Transportation

Fuel is one of the largest sources of federal excise tax revenue. The taxes vary by fuel type:

• Gasoline: approximately $0.184 per gallon
• Diesel fuel: approximately $0.244 per gallon
• Aviation fuel: varies by use (commercial vs. general aviation)
• Kerosene: rates depend on use and where it's purchased

Businesses that operate vehicle fleets, run transportation services, or sell fuel must account for these taxes.

Alcohol and Tobacco

These are classic "sin taxes" designed to discourage consumption while generating revenue:

• Beer: rates based on barrel volume, with lower rates for small brewers
• Wine: rates vary by alcohol content and type
• Distilled spirits: approximately $13.50 per proof gallon (with reduced rates for smaller producers)
• Cigarettes: $1.01 per pack of 20
• Cigars, pipe tobacco, and smokeless tobacco: rates vary by weight and type

Manufacturers, importers, and some distributors are responsible for collecting these taxes.

Air Transportation

Travelers pay excise taxes on domestic airline tickets (7.5% of the ticket price) and on segments of domestic flights ($4.50 per segment as of recent rates). Businesses operating aircraft or booking significant travel should be aware of how these taxes appear on their books.

Heavy Vehicles and Tires

• Heavy trucks and trailers: 12% excise tax on the first retail sale of trucks over 33,000 pounds gross vehicle weight
• Tires: taxed per pound of rubber over a certain weight threshold (mainly applies to heavy-use tires)

If your business purchases or sells heavy commercial equipment, this tax affects your total cost of acquisition.

Environmental Taxes

Certain chemicals and substances that harm the ozone layer are subject to excise taxes. Coal is also taxed to fund the Black Lung Disability Trust Fund. Businesses in mining, chemical manufacturing, or energy production may face these levies.

Health-Related Taxes

• Indoor tanning services: 10% tax on the amount paid for tanning services
• Vaccines: a small excise tax applies to certain childhood vaccines, funding the National Vaccine Injury Compensation Program

Firearms and Ammunition

The federal government levies excise taxes on the manufacture and importation of firearms and ammunition:

• Pistols and revolvers: 10%
• Other firearms: 11%
• Ammunition: 11%

These taxes fund wildlife restoration programs under the Pittman-Robertson Act.

How Excise Tax Is Calculated

Excise taxes use two calculation methods:

Per-unit (specific) tax: A fixed amount per unit of quantity—gallons, packs, pounds, etc. For example, $0.184 per gallon of gasoline regardless of the price at the pump.

Ad valorem tax: A percentage of the sale price. For example, 7.5% on domestic airline tickets.

Some categories combine both methods. Calculating your excise tax liability accurately requires knowing which method applies to your specific product and staying current on the applicable rates, which Congress adjusts periodically.

Who Is Responsible for Paying Excise Tax?

The party responsible for excise tax depends on the product:

• Manufacturers and importers: For most goods like alcohol, tobacco, firearms, and heavy trucks, the liability falls on the manufacturer or first importer
• Retailers: For services like indoor tanning
• Operators: For businesses like airlines or fuel distributors

If you're unsure whether your business has excise tax obligations, the IRS publishes Publication 510 (Excise Taxes), which catalogs all federally taxable goods and services. A tax professional familiar with your industry can also help you assess your exposure.

How to File and Pay Excise Taxes

Form 720: Quarterly Federal Excise Tax Return

Most businesses that owe federal excise taxes report them using IRS Form 720. This return is filed quarterly, with deadlines falling on:

• April 30 (for January–March)
• July 31 (for April–June)
• October 31 (for July–September)
• January 31 (for October–December)

Form 720 has two parts covering different categories of excise taxes, plus schedules for calculating deposits. The instructions are detailed—give yourself time to review them or work with an accountant the first time through.

Payment Frequency

How often you pay depends on how much you owe:

• Under $2,500 per quarter in Part I liability: You can pay when you file the quarterly return
• Over $2,500 per quarter in Part I liability: You must make semi-monthly deposits (deposits due every two weeks)

This semi-monthly deposit requirement catches many businesses off guard. Missing a deposit deadline triggers the same trust fund penalty rules as payroll taxes—penalties can be steep.

How to Pay

The IRS requires electronic payment for most excise tax deposits. Use the Electronic Federal Tax Payment System (EFTPS). You'll need to enroll if you haven't already—enrollment can take up to five business days, so don't wait until a deadline is approaching.

Some businesses use authorized third parties (payroll processors, tax software, or accountants) to handle EFTPS deposits on their behalf.

State Excise Taxes

Federal excise taxes are just one layer. Most states impose their own excise taxes, particularly on:

• Gasoline and diesel
• Alcohol and beer
• Tobacco products
• Gambling and lottery proceeds

State rates and rules vary significantly. A business selling fuel in multiple states must track different per-gallon tax rates, reporting requirements, and payment schedules for each state. Multi-state excise tax compliance is one area where specialized software or a tax consultant pays for itself quickly.

Common Mistakes Businesses Make with Excise Tax

Not knowing you owe it: This is the most common problem. Excise tax obligations aren't always obvious—a small manufacturer who starts selling heavy trucks, or a salon owner who adds tanning beds, may not realize they've crossed into excise tax territory.

Missing deposit deadlines: The semi-monthly deposit schedule for larger filers is easy to overlook. Set calendar reminders or automate these payments.

Incorrect rate application: Rates change, and applying an outdated rate means either overpaying or underpaying. The IRS adjusts certain excise tax rates annually.

Poor recordkeeping: Excise tax audits do happen. Keeping detailed records of units sold, prices charged, and taxes collected makes audits far less painful.

Commingling tax funds: The excise taxes you collect aren't your money—they're held in trust for the government. Keep them in a separate account to avoid accidentally spending funds that belong to the IRS.

Excise Tax Exemptions

Some buyers qualify for excise tax exemptions or credits:

• Tax-exempt organizations (nonprofits, government agencies) may be exempt from certain excise taxes
• Exports: Products exported from the US are generally not subject to federal excise tax
• Certain uses of fuel: Farmers, off-highway vehicles, and some other uses may qualify for fuel tax credits or refunds via Form 4136

If your customers include entities that may qualify for exemptions, it's worth understanding how to document those exemptions properly to avoid liability.

How Excise Tax Affects Your Business Finances

From a financial reporting standpoint, excise taxes collected from customers pass through your books but aren't your revenue—similar to sales tax. However, excise taxes you pay as a cost of doing business (for example, if you purchase taxed fuel for a fleet) are generally deductible business expenses.

Here's a simplified flow:

1. You sell a taxable good or service
2. You embed the excise tax in the price (or charge it separately)
3. The collected tax sits in a liability account on your balance sheet
4. When you file and pay, you clear the liability

This means accurate bookkeeping requires tracking excise tax collections separately from revenue. If your accounting system lumps excise taxes into revenue, you'll overstate income and face a distorted picture of your business's financial health.

Keep Your Financial Records Clean

Excise tax compliance depends heavily on accurate, organized records. You need to track:

• Units sold by taxable category
• Tax collected from customers
• Payments remitted to the IRS (with dates)
• Exemption certificates from qualifying buyers

Messy books make this nearly impossible—and make IRS inquiries much more stressful.
