What Form 720 Means: Quarterly Federal Excise Tax Return

Form 720 is the IRS’s Quarterly Federal Excise Tax Return, the return businesses use to report and pay federal excise taxes on specific goods and services such as fuel, air transportation, communications, indoor tanning, heavy trucks, sport fishing and archery equipment, foreign insurance, and certain health coverage. If your business sells or provides anything on the form’s list of taxable activities during a calendar quarter, you owe a Form 720 for that quarter, and in most cases you also owe deposits twice a month rather than a single payment at quarter’s end.¹

Excise taxes are transaction taxes, not income or payroll taxes. Some are collected from a customer (the 10% indoor tanning tax, the 7.5% tax on airline tickets, the 3% communications tax). Others are owed by the manufacturer, importer, or first retail seller (fuel, sport fishing gear, heavy trucks). Either way, Form 720 is where the liability lands.

What Excise Taxes Get Reported on Form 720

The form splits into two parts. Part I covers environmental taxes, communications taxes, air transportation taxes, and fuel taxes. Part II covers manufacturers’ taxes, retail taxes, and a handful of specialized levies.²

Part I: Environmental, Communications, Air Transportation, and Fuel

Environmental taxes apply to petroleum, taxable chemicals, ozone-depleting chemicals, and imported chemical substances. Filers reporting these amounts also attach Form 6627, which breaks the environmental liability out by category.³

The communications tax is 3% of amounts paid for local telephone and similar services, collected by the service provider and remitted on Form 720.⁴

Air transportation of passengers carries a 7.5% tax on the ticket price plus a per-segment fee for domestic flights, with separate per-passenger amounts for international departures and arrivals. Air freight is taxed at 6.25% of the amount charged.⁵

Fuel taxes cover gasoline, diesel, kerosene, and various alternative fuels on a per-gallon basis, and are a major source of Highway Trust Fund revenue. Rates vary by fuel type and use, and each category has its own IRS number on the form.

Part II: Manufacturers, Retail, Indoor Tanning, Foreign Insurance, and the PCORI Fee

Manufacturers’ taxes hit specific goods at the point of sale from the manufacturer. Sport fishing equipment is taxed at 10% of the sales price, and archery equipment carries rates that vary by item, including a per-shaft amount for arrow shafts.⁶

The retail excise tax is 12% of the sales price on the first retail sale of heavy trucks, trailers, and tractors, and only applies above set weight thresholds: 33,000 pounds gross vehicle weight for trucks, 26,000 for trailers, and 19,500 for tractors (or a gross combined weight over 33,000 pounds when paired with a trailer).⁷

Indoor tanning services are taxed at 10% of the amount paid, collected by the tanning provider from the customer.⁸ Excise taxes on foreign insurance policies apply per dollar of premium, at rates that depend on whether the coverage is casualty, life, sickness and accident, indemnity, or reinsurance.⁹

The Patient-Centered Outcomes Research Institute (PCORI) fee is a Form 720 item with an unusual schedule: health insurance issuers and sponsors of self-insured health plans report it once a year on the second-quarter Form 720, due July 31, based on the number of covered lives during the plan year.¹⁰

Q1 (January through March): April 30
Q2 (April through June): July 31
Q3 (July through September): October 31
Q4 (October through December): January 31 of the following year

When a due date falls on a weekend or federal holiday, it moves to the next business day.

Semi-Monthly Deposits and the Small-Filer Exception

Most filers don’t wait for the quarterly return to pay. Each month is divided into two deposit periods, the 1st through the 15th and the 16th through the last day, and the deposit for each period is due within 14 days after the period ends. Each deposit must cover at least 95% of the actual net tax liability for that semi-monthly period, with any shortfall reconciled on the quarterly return.¹¹

September breaks the pattern. The IRS splits the second half of September into shorter windows, creating a third deposit period in that month. The exact dates change year to year, so check the Form 720 instructions in September.¹²

Smaller filers get a break. If your total net liability for Part I taxes for the entire quarter is $2,500 or less, you can skip the semi-monthly deposits and pay the balance with the quarterly return.¹¹

How to File Form 720

Accurate filing depends on tracking every taxable transaction during the quarter: gallons sold, tickets collected, units manufactured, services provided. You match each activity to its IRS number in Part I or Part II and apply the correct rate or per-unit amount.

The totals feed Part III, where you compute the tax due for the quarter. If you made semi-monthly deposits, you also complete Schedule A to show how the liability breaks down by deposit period. Schedule C is where you claim allowable credits or refunds, most often for fuel-related overpayments.¹

You can file on paper by mailing the return to the IRS service center listed in the instructions, or electronically through an IRS-approved e-file provider. Deposits and final payments go through the Electronic Federal Tax Payment System (EFTPS). If you mail a paper return with a check or money order, include Form 720-V so the payment posts to the right account.¹³

Keep a full copy of every filed return and its schedules. To fix an error on a return you already filed, use Form 720-X, the Amended Quarterly Federal Excise Tax Return. Form 720-X corrects liability figures; it cannot be used to change most Schedule C credit claims.¹⁴

Registering First With Form 637

Some Form 720 activities require IRS registration before you can operate. Fuel activities are the main example: to buy or sell certain fuels tax-free or to claim certain fuel credits, you first file Form 637, Application for Registration (For Certain Excise Tax Activities), identifying your activity by the designated letter (for instance, Activity Letter M covers blending of gasoline, diesel, or kerosene, including biodiesel and renewable diesel mixtures). Once the IRS approves your application, sometimes after inspecting your premises, it issues a Letter of Registration.¹⁵

Failing to register when you’re required to is expensive: $10,000 per failure plus $1,000 for every day the failure continues.¹⁶ File Form 637 before you begin the taxable activity, not after.

Penalties for Filing or Paying Late

The general late-filing and late-payment framework applies. If you file Form 720 late without reasonable cause, the penalty is 5% of the unpaid tax for each month or partial month the return is overdue, capped at 25%.¹⁷

If you file on time but underpay, the late-payment penalty is 0.5% of the unpaid balance per month, also capped at 25%. When both penalties run in the same month, the late-filing penalty is reduced by the late-payment penalty, so the combined rate is 5% per month rather than 5.5%. If you receive a notice of intent to levy and still don’t pay within 10 days, the late-payment penalty doubles to 1% per month. Interest also runs, and it compounds daily.¹⁷

Once You File, You Keep Filing

Form 720 is a recurring obligation. After your first return, you must file every quarter until you submit a final return, even for quarters when you owe no excise tax. In a zero-liability quarter, you file with zeros on the relevant lines. To stop the cycle, check the “Final” box when you go out of business or no longer expect to owe any of the taxes listed on the form.¹
