IRS Form 720 Guide: Quarterly Federal Excise Tax Return

1. Introduction – What is Form 720?

IRS Form 720, officially titled Quarterly Federal Excise Tax Return, is a mandatory business tax return governed by the Internal Revenue Service (IRS). It is used by commercial entities to calculate, report, and pay federal excise taxes on specific goods, commercial services, and industry activities.

Unlike standard federal income tax or payroll tax, excise taxes are indirect taxes levied on specific transactions. Form 720 covers a broad spectrum of commercial industries, including fuel distribution, commercial aviation, telecommunications, heavy truck retail sales, indoor tanning services, environmental chemical manufacturing, and self-insured healthcare plans.

Form 720 is filed on a quarterly basis, providing the federal government with ongoing accounting and revenue collection for statutory excise tax programs.

2. Purpose of the Form

The primary purpose of Form 720 is to collect federal excise revenue designated by Congress to fund public infrastructure, trust funds, environmental protection, and medical research programs.

Form 720 solves the operational challenge of administering specialized activity taxes. For example, federal excise taxes collected on gasoline and heavy highway trucks fund the Federal Highway Trust Fund, while taxes collected on commercial airline tickets fund the Airport and Airway Trust Fund. Form 720 provides the structured reporting mechanism to funnel these industry-specific taxes into their corresponding federal funds.

In addition, Form 720 enforces compliance with mandatory semi-monthly tax deposits. Rather than allowing businesses to hold large excise tax balances until the end of a quarter, federal law requires ongoing tax deposits through the Electronic Federal Tax Payment System (EFTPS).

3. Who Needs to File This Form

Form 720 must be filed by any business, corporation, partnership, or sole proprietor that operates in an industry subject to federal quarterly excise taxes.

You must file Form 720 if your business conducts any of the following commercial activities:

• Fuel Producers and Wholesalers: Refiners, blenders, terminal operators, and wholesale distributors of gasoline, diesel fuel, aviation fuel, kerosene, and alternative fuels.
• Transportation & Communications Providers: Commercial airlines, air charter services, international air passenger transportation providers, and local/toll telephone service providers.
• Retail Truck and Trailer Dealers: Retail sellers of heavy highway trucks, truck chassis, semi-trailers, and highway tractors.
• Manufacturers & Importers: Manufacturers of coal, sporting firearms, bows and arrows, fishing equipment, vaccines, or Superfund taxable chemicals.
• Indoor Tanning Salons: Providers of indoor UV tanning services (subject to a 10% federal excise tax).
• Sponsors of Self-Insured Health Plans: Employers and plan sponsors subject to the annual Patient-Centered Outcomes Research Trust Fund (PCORI) fee.

4. Who Is Exempt / Not Required to File

Form 720 is restricted to specific excise-taxable goods and services. Most general retail and service businesses are exempt.

You are NOT required to file Form 720 in the following situations:

• Standard Retail Merchants: Retail businesses selling non-excise consumer goods, clothing, electronics, or general merchandise.
• Standard Service Providers: Professional service providers (such as law firms, accounting firms, or IT consultants) that do not provide taxable communications or transportation services.
• Non-Excise Payroll & Income Filers: Businesses filing routine quarterly employer payroll tax returns (Form 941) or annual corporate income tax returns (Form 1120) without engaging in excise activities.
• Heavy Vehicle Owners (Form 2290 Filers): Trucking companies paying the annual Heavy Highway Vehicle Use Tax file Form 2290 rather than Form 720.

5. When to File

Form 720 is a quarterly return filed four times a year. However, specific tax categories follow distinct deposit schedules.

Review the quarterly filing due dates below:

Tax Quarter	Quarterly Period Covered	Form 720 Filing Due Date
Quarter 1	January 1 – March 31	April 30
Quarter 2	April 1 – June 30	July 31 (Includes annual PCORI healthcare fee)
Quarter 3	July 1 – September 30	October 31
Quarter 4	October 1 – December 31	January 31 (of the following year)

If any filing due date falls on a Saturday, Sunday, or official legal holiday, the deadline automatically extends to the next business day.

6. Where and How to File

Form 720 can be submitted electronically through approved IRS e-file software or filed by paper mail.

Electronic Filing (Recommended)

The IRS strongly encourages electronic filing for Form 720 through authorized Modernized e-File (MeF) software providers. E-filing ensures faster processing, immediate receipt confirmation, and seamless integration with electronic payment systems.

Paper Filing and Semi-Monthly Payments

If filing a paper return, mail the completed Form 720 package to the designated IRS Service Center address listed in the current official instructions (typically the IRS Center in Ogden, UT).

For taxes listed in Part I (fuels, communications, heavy trucks), you must make semi-monthly deposits via EFTPS during the quarter. Small quarterly balances for Part II taxes can be paid with the return using Form 720-V (Payment Voucher).

7. Step-by-Step Instructions to Fill the Form

Form 720 is structured into three primary computation parts and supporting Schedules A, C, and T. Review the summary guide below.

Part I – Taxes Subject to Semi-Monthly Deposits

Part I covers high-volume excise tax categories, including fuel taxes, commercial air passenger taxes, communications taxes, Superfund chemical taxes, and heavy truck retail sales. For each category, enter the total taxable units (gallons, ticket sales, or dollar amounts), multiply by the statutory IRS tax rate, and enter the total tax liability. Taxes listed in Part I require ongoing semi-monthly EFTPS deposits throughout the quarter.

Part II – Taxes Not Subject to Semi-Monthly Deposits

Part II covers tax categories that do not require semi-monthly advance deposits. Key items include:

• Indoor Tanning Services: 10% gross tax on indoor UV tanning receipts.
• PCORI Health Plan Fees: Reported exclusively on the **Second Quarter return (due July 31)** by employers sponsoring self-insured health plans, calculated per covered life.
• Sport Fishing & Arrow Manufacturers: Specific sporting goods manufacturing excise taxes.

Part III – Reconciling Taxes and Deposits

Part III combines the total tax liabilities from Part I and Part II. Subtract all semi-monthly deposits made via EFTPS during the quarter and subtract allowable fuel tax credits claimed on Schedule C. The resulting balance is the net tax due (or overpayment available for refund or credit).

Schedule A – Record of Semi-Monthly Tax Liabilities

If you report tax liabilities in Part I, you **must complete Schedule A**. Schedule A breaks down your exact tax liabilities across six semi-monthly periods during the quarter, allowing the IRS to verify that your advance EFTPS deposits met statutory semi-monthly deposit rules.

8. Required Documents/Information Needed Before Filling

To accurately complete Form 720, gather detailed operational accounting logs and payment confirmation records prior to filing.

Ensure you have the following verification materials ready:

• Sales & Volume Registers: Detailed fuel sales logs (gallons), airline ticket sales reports, gross indoor tanning receipts, or truck retail invoices.
• EFTPS Deposit Confirmations: Official EFTPS payment confirmation records showing dates and dollar amounts for all semi-monthly deposits made during the quarter.
• PCORI Plan Enrollment Records: Average covered life counts for self-insured health plans (for Q2 filings).
• Form 637 Registration Letters: IRS activity registration numbers for fuel blenders, refiners, or bulk transporters.
• Fuel Credit Invoices: Fuel purchase invoices and usage logs if claiming tax-paid fuel credits on Schedule C.

9. Common Mistakes to Avoid

Filing errors on Form 720 can lead to substantial deposit penalties and interest charges. Avoid these frequent mistakes:

• Failing to Make Semi-Monthly Deposits: Holding Part I tax funds and paying the entire balance at the end of the quarter with Form 720. Paying quarterly instead of semi-monthly triggers severe **Failure-to-Deposit penalties** under Section 6656.
• Missing the July 31 PCORI Filing Deadline: Forgetting that employers sponsoring self-insured health plans must file Q2 Form 720 by July 31 annually to pay PCORI fees.
• Omitting Schedule A: Reporting Part I taxes without completing Schedule A to detail semi-monthly liability periods.
• Confusing Form 720 with Form 2290: Attempting to pay annual heavy vehicle use taxes on Form 720 instead of filing dedicated Form 2290.
• Failing to File Zero Returns: Failing to file Form 720 for a quarter after registering an excise account, even if no taxable activity occurred during that specific quarter.

10. Penalties for Non-Filing or Errors

Failing to file Form 720, making late payments, or missing semi-monthly deposit deadlines carries strict civil penalties under the Internal Revenue Code.

Key penalty risks include:

• Failure-to-Deposit Penalty (IRC Section 6656): Penalties ranging from 2% to 10% of the underdeposited tax amount for late or missing semi-monthly EFTPS deposits (increasing to 15% if unpaid after IRS notice).
• Late Filing Penalty (IRC Section 6651(a)(1)): Charged at 5% of unpaid tax per month, up to a maximum of 25%.
• Late Payment Penalty (IRC Section 6651(a)(2)): Charged at 0.5% of unpaid tax per month, up to a maximum of 25%, plus mandatory compounding interest.

11. Related Forms or Schedules

Form 720 operates alongside several core federal excise and business tax forms:

• Form 637: Application for Registration (For Certain Excise Tax Activities).
• Form 2290: Heavy Highway Vehicle Use Tax Return.
• Form 8849: Claim for Refund of Excise Taxes (used to claim off-quarter fuel refunds).
