IRS Form 872-B – IRS Forms, Instructions, Pubs 2026 – In the complex world of tax compliance, understanding specific IRS forms can save time and prevent costly mistakes. IRS Form 872-B, officially titled “Consent to Extend the Time to Assess Miscellaneous Excise Taxes,” plays a crucial role for taxpayers dealing with excise tax examinations. Whether you’re a business owner handling fuel taxes, wagering operations, or heavy vehicle use taxes, this form allows you to voluntarily extend the IRS’s assessment period. This comprehensive guide explains what Form 872-B is, its purpose, when to use it, step-by-step filling instructions, and key taxpayer rights—drawing from official IRS sources and procedures as of 2026.
What Is IRS Form 872-B?
IRS Form 872-B is a formal agreement between a taxpayer (or their authorized representative) and the Internal Revenue Service (IRS) to extend the statute of limitations for assessing miscellaneous excise taxes. Miscellaneous excise taxes include those on fuels, environmental items, communications, air transportation, wagering, and heavy highway vehicles. The form is typically used during IRS audits or examinations when more time is needed to resolve issues without rushing to an assessment.
The form was last revised in December 2004 and remains the current version as posted on the IRS website in March 2024, with no major updates noted through 2026. It specifies the type of tax, the relevant Internal Revenue Code (IRC) section, the tax period, and the new expiration date for assessment.
Key elements from the form include:
- Taxpayer Information: Name, address, and Taxpayer Identification Number (TIN).
- Consent Clauses: Three main agreements covering assessment timing, collection provisions, and refund claims.
- Signatures: Required from the taxpayer, representatives, and IRS officials.
This extension applies to taxes reported on forms like Form 720 (Quarterly Federal Excise Tax Return), Form 2290 (Heavy Highway Vehicle Use Tax), Form 730 (Monthly Tax Return for Wagers), and Form 11-C (Occupational Tax and Registration for Wagering).
Purpose of Form 872-B
The primary purpose of IRS Form 872-B is to provide additional time for both the taxpayer and the IRS during an excise tax examination. Under IRC Section 6501, the IRS generally has three years from the return’s filing date (or due date, if later) to assess taxes. If this period is nearing expiration and issues remain unresolved, the IRS may request an extension to avoid issuing a premature notice of deficiency.
Benefits for taxpayers include:
- More time to gather documentation and clarify disputes.
- Opportunity to negotiate resolutions collaboratively.
- Avoidance of rushed assessments that could lead to higher liabilities.
For the IRS, it allows thorough development of complex issues, such as those involving multiple tax types on a single return. However, signing is voluntary—taxpayers can refuse or limit the extension to specific issues or periods.
When Should You Use Form 872-B?
Use Form 872-B when undergoing an IRS excise tax audit and the statute of limitations is approaching (typically within 180 days of expiration). It’s solicited in unusual circumstances, such as fraud investigations, joint probes with other agencies, or when additional examination time is needed.
Common scenarios include:
- Audits of fuel or environmental taxes under IRC Section 4081 or 4041.
- Wagering or occupational taxes under IRC Sections 4401 or 4411.
- Heavy vehicle use taxes under IRC Section 4481.
- Cases where the taxpayer acts as a collector (e.g., for air transportation taxes under IRC Section 4261), requiring specific model language in the consent.
If multiple excise taxes are involved on the same return (e.g., Form 720), each type and its IRC section must be listed separately. For penalties like those under IRC Section 6725 (failure to report on Form 720-TO or 720-CS), modify the form by replacing “tax” with “penalty.”
Note: This form differs from Form 872 (for income taxes) or other specialized consents like Form 872-P for partnerships.
How to Fill Out IRS Form 872-B: Step-by-Step Instructions?

- For collectors, add language like: “The taxpayer(s) may file a claim for credit or refund… under section 7501, 4291, etc.”
- For LLCs treated as corporations for excise taxes (post-2007 periods), secure consent from the LLC entity.

Signing and Filing Form 872-B
The IRS typically initiates the request via Letter 907, accompanied by Publication 1035 (“Extending the Tax Assessment Period”). Review these documents carefully.
- Who Can Sign?: The taxpayer, attorney/agent (with power of attorney), fiduciary, or corporate officer. For partnerships, one authorized partner suffices.
- Filing: Submit the signed form to the IRS examiner. Keep a copy for records.
- After Signing: The IRS updates internal systems (e.g., AIMS/ERCS) and sends a confirmation via Letter 929.
Negotiate terms: Request justification for the extension length, limit to specific issues, or tie to milestones like appeal resolutions.
Taxpayer Rights and Considerations
You have the right to refuse signing Form 872-B or limit it under IRC Section 6501(c)(4)(B). Refusal may lead to protective assessments, but signing doesn’t waive appeal rights.
Risks include accruing interest/penalties during the extension and potential expansion of audit scope. Benefits: More collaborative resolution. Always consult a tax professional before signing.
