IRS Form 720 is the Quarterly Federal Excise Tax Return used to report and pay specified federal excise taxes identified by IRS number.
The form covers multiple unrelated excise-tax regimes, so filing depends on the taxpayer’s products, services, activities, and registrations. It is not a general sales-tax return.

What Is IRS Form 720?
Form 720 reports liabilities such as certain environmental, communications, air transportation, fuel, retail, manufacturers, indoor tanning, and health-related excise taxes, depending on current law and form lines.
Some taxes require semimonthly deposits even though the return is quarterly. Filing the return does not replace deposits that were due earlier.
Who Should Use IRS Form 720?
- Businesses liable for one or more excise taxes listed in Parts I or II.
- Registered fuel businesses and other entities reporting activities by IRS number.
- Insurers, manufacturers, retailers, service providers, or facility operators covered by a specific excise-tax provision.
- Entities claiming allowable credits or payments through Schedule C.
- Not every business; a filing obligation must arise from a tax listed in the form instructions.
How to Use or Complete IRS Form 720
- Identify every activity and IRS number that creates an excise-tax liability for the quarter.
- Maintain quantity, sales, service, passenger, policy, or other tax-base records required for each line.
- Calculate Part I and Part II taxes under the line-specific rules.
- Complete Schedule A when required to report the deposit liability schedule.
- Complete Schedule T or Schedule C when fuel transactions, claims, credits, or payments require them.
- Reconcile total tax, deposits, overpayments, balance due, and any third-party-designee information.
- File electronically or mail by the quarterly due date and pay any permitted balance through an authorized method.
Form 720 Quarterly Due Dates
When a due date falls on a weekend or legal holiday, the next-business-day rule may apply. A taxpayer that permanently stops a covered activity should follow the final-return instructions.
| Quarter | Months covered | General due date |
|---|---|---|
| First | January–March | April 30 |
| Second | April–June | July 31 |
| Third | July–September | October 31 |
| Fourth | October–December | January 31 |
Deposits Are Different From Filing
Many Part I taxes follow semimonthly deposit rules and may require EFTPS. Schedule A reports the net liability for each semimonthly period and must reconcile to the return.
A balance paid with Form 720 may not cure a failure to make required deposits on time. Deposit penalties can apply separately from a late-return or late-payment penalty.
Important Schedules
- Schedule A: excise tax liability by semimonthly period for deposit reporting.
- Schedule T: reporting certain two-party exchanges and terminal-related fuel transactions.
- Schedule C: claims, credits, and payments for eligible fuels and other listed items.
- Form 6627: environmental taxes when required by the current Form 720 package.
- Form 720-X: amended quarterly return for covered corrections under its instructions.
IRS Numbers and Activity Records
Each excise tax line has an IRS number. Do not place an amount on a line merely because the activity sounds similar; read the definition, rate, exclusions, and special rules for that exact number.
Retain source records that explain taxable units, rates, exemptions, resale certificates, registrations, and deposits. Fuel and transportation taxes often involve specialized documentation.
Before You File or Submit
- Use the current official version. Tax forms, addresses, thresholds, and electronic filing procedures can change. Download the form or instructions from the issuing agency immediately before use.
- Match names and taxpayer identification numbers. Confirm that legal names, SSNs, ITINs, EINs, plan numbers, and tax periods agree with the related return and agency records.
- Gather supporting records first. Keep calculations, statements, notices, authorizations, appraisals, receipts, and other documents that support every entry.
- Check the deadline and delivery method. An extension to file does not necessarily extend the time to pay. Private carriers also may require a different street address than USPS.
- Sign where required. An unsigned paper form, missing consent, or incomplete electronic authentication can delay or invalidate a submission.
- Keep a complete copy. Retain the filed form, attachments, confirmation number, proof of mailing, fax confirmation, and payment record.
Common Mistakes to Avoid
- Treating Form 720 as a general sales-tax form.
- Reporting the correct amount under the wrong IRS number.
- Filing quarterly but missing semimonthly deposits.
- Failing to reconcile Schedule A with Part I tax.
- Claiming a Schedule C credit without required registration or supporting records.
- Ignoring a final-return indicator after ending the taxable activity.
What Happens After Submission?
The IRS posts the return and deposits to the excise-tax account. A mismatch between the return, Schedule A, EFTPS deposits, or registration records can generate a notice.
Review any notice line by line and compare it with the retained liability schedule. Use Form 720-X only when its correction rules apply rather than changing a later quarter without authority.
Processing time is not the same as a legal deadline. Do not submit a duplicate merely because an acknowledgement or response has not arrived. First check the relevant online status tool, confirmation record, or official contact channel. If the agency requests more information, respond by the date and method stated in the notice.
Records to Keep
Keep a copy of the completed submission and all documents used to prepare it. Your file should also contain the tax-year or period involved, the date submitted, the delivery method, any confirmation or tracking number, and notes about later agency correspondence. Retention periods depend on the form and issue, so follow the specific instructions and keep records longer when they may remain material to an audit, refund claim, basis calculation, collection case, election, or amended return.
