TL;DR: In Fine v. Commissioner, 167 T.C. No. 13 (2026), the U.S. Tax Court ruled that a taxpayer who signs a fixed-date IRS audit extension on Form 872 cannot use Form 872-T to cancel it early. The extension stays in force until its stated expiration date, which means the IRS retains full authority to issue a tax assessment for your open year through that date. If you are facing an open audit or a Notice of Deficiency, exploring your tax debt relief options immediately is critical.
By Fresh Start Initiative
Getting a letter from the IRS asking you to extend the time it has to audit your return is one of the most stressful moments a taxpayer can face. You may not fully understand what you are agreeing to, and if negotiations later break down, you might assume you can simply pull the plug on the extension and force the IRS to act quickly or walk away. A brand-new Tax Court decision says that is not how it works.
The ruling in Fine v. Commissioner clarifies a procedural rule that affects thousands of taxpayers currently in the middle of IRS examinations. Understanding this decision is not just an academic exercise. It has real consequences for how long the IRS can come after you for additional tax, penalties, and interest on any year you left “open” through a signed consent form.
This article breaks down what happened in the case, what it means for ordinary taxpayers, and what steps you can take right now to protect yourself and explore available tax debt relief programs.
The Basics: What Is the IRS Statute of Limitations on Assessment?
Under IRC Section 6501(a), the general rule is that the IRS must assess any additional tax within three years after your return is filed. This deadline is known as the Assessment Statute Expiration Date, or ASED. Once it passes, the IRS permanently loses the right to assess more tax for that year, even if it later discovers a clear error.
The three-year window can stretch to six years if you omit more than 25 percent of your gross income from your return. And if you never filed a return at all, or filed a fraudulent one, the IRS has unlimited time. For most people in a standard audit, though, the three-year clock is the key number to understand.
The IRS and a taxpayer can agree in writing to extend that deadline. According to IRS Internal Revenue Manual Section 25.6.22, this is done using either Form 872 (a fixed-date extension) or Form 872-A (an open-ended extension). These are two very different tools with very different consequences, and the distinction is at the heart of the Fine decision.
Form 872 vs. Form 872-A: A Critical Difference
When the IRS asks to extend your audit clock, it will typically propose one of two forms. Knowing which one you are signing matters enormously.
| Feature | Form 872 (Fixed-Date Consent) | Form 872-A (Open-Ended Consent) |
|---|---|---|
| Duration | Extends to a specific calendar date agreed upon by both parties | Extends indefinitely, with no stated end date |
| How it ends | Automatically on the stated expiration date, or if the IRS issues a Notice of Deficiency, or both parties sign a new written agreement | 90 days after the IRS or taxpayer sends Form 872-T, or upon IRS issuance of a Notice of Deficiency |
| Can taxpayer terminate early with Form 872-T? | No, per Fine v. Commissioner | Yes, Form 872-T is the designated termination tool |
| Typical use | Standard audit extensions where both parties agree on a specific window | Complex audits, appeals, or situations requiring flexible timelines |
| Statutory authority | IRC § 6501(c)(4)(A) | IRC § 6501(c)(4)(A) |
| Taxpayer right to refuse | Yes, under IRC § 6501(c)(4)(B) | Yes, under IRC § 6501(c)(4)(B) |
IRS Publication 1035, Extending the Tax Assessment Period, explains that a fixed-date consent sets a specific expiration date, while an open-ended consent extends the statute for an indefinite period of time. The IRS is required by law to inform you of your right to refuse to sign either form, or to limit the extension to particular issues or a particular tax period.
What Happened in Fine v. Commissioner
The taxpayers in Barry Holmes Fine and Monica Dias v. Commissioner signed Forms 872 agreeing to extend the statute of limitations on their 2015 and 2016 tax years to specific fixed dates. When settlement negotiations with the IRS Appeals division stalled and the taxpayers became dissatisfied with the pace of the process, they tried to force the IRS’s hand. They faxed Forms 872-T to the IRS, attempting to terminate the extensions early.
Their argument was straightforward: they sent a Form 872-T, the IRS did not issue Notices of Deficiency within 90 days of receiving it, so the assessments should be barred by the statute of limitations. The Tax Court rejected this argument entirely.
The court held that Form 872-T does not terminate a properly executed Form 872, and therefore the Notices of Deficiency issued by the IRS were timely and not barred by the statute of limitations. The court granted partial summary judgment in the IRS’s favor.
The Tax Court’s reasoning was grounded in the plain language of the forms themselves. Drawing on general contract principles, the court emphasized that Form 872-A expressly references Form 872-T, Form 872-T references only Form 872-A, and Form 872 says nothing about Form 872-T. The conclusion was that “only the passage of time can terminate Form 872.” This is now a precedential opinion, meaning it binds future Tax Court cases on the same question.

If you have already signed a Form 872, this decision carries immediate practical consequences. You cannot simply change your mind mid-audit and use a Form 872-T to cut the extension short. Your open year remains exactly that, open, until the date written on your signed form.
This matters because the IRS retains full authority to issue a Notice of Deficiency, propose additional tax, and assess penalties and interest for any year covered by your Form 872 right up through the stated expiration date. If you were counting on using Form 872-T as a pressure tactic during settlement negotiations, that strategy is now off the table.
The ruling also reinforces that strategic dissatisfaction with how an audit or appeals process is going does not give a taxpayer the right to unilaterally alter an extension they voluntarily agreed to. As one analysis noted, the ruling underscores the binding nature of fixed-term waivers and the strict interpretive rules applied to IRS consent forms.
If you owe additional tax after the audit is resolved, the clock does not stop there. You still need a plan to handle the resulting tax debt. That is where understanding your tax debt relief options becomes essential.
Your Rights Before You Sign: What the Law Requires the IRS to Tell You
One of the most important protections in this area is one many taxpayers never hear about. Before you sign any audit extension form, the IRS is legally required to inform you of specific rights. Knowing them before you put pen to paper can change the outcome of your case.
Under IRS Internal Revenue Manual Section 25.6.22, the IRS must notify you of the following rights before requesting a statute extension:
- The right to refuse entirely. You can say no to a Form 872 or Form 872-A. Signing is never mandatory. If you refuse, the IRS will likely issue a Notice of Deficiency based on the information it already has, which you can then challenge in Tax Court.
- The right to limit the extension to specific issues. You do not have to agree to keep every potential issue open. A “restricted consent” limits the extension to only the issues actually under examination.
- The right to limit the extension to a specific period of time. You can negotiate a shorter window than the IRS proposes. You are not required to accept whatever date they put on the form.
- The right to choose between a fixed-date and an open-ended extension. Understanding the Form 872 vs. Form 872-A distinction, as clarified by the Fine ruling, is now more important than ever. A fixed-date form cannot be terminated early, period.
- The right to retain all appeal rights. Signing a consent form does not waive your right to appeal the IRS’s findings. You keep all appeal options you would otherwise have.
- The right to consult a representative. You may speak with a tax professional, including an enrolled agent or attorney, before making any decision about signing an extension.
The IRS sends these disclosures with Publication 1035, Extending the Tax Assessment Period, and Letter 907. Ask for them if you do not receive them. Document that you were informed of your rights before signing anything.

Check Your Eligibility →What to Do If You Have Already Signed a Form 872
If you have already signed a fixed-date Form 872 and are now wondering what your options are, the Fine ruling makes clear that early termination through Form 872-T is not one of them. Here is what you can do instead:
- Negotiate a shorter extension going forward. When your current Form 872 approaches its expiration date, you may be asked to sign another one. At that point, you can negotiate a narrower window, restricted issues, or decline altogether.
- Push the audit toward resolution. Work with your tax professional to supply requested documentation promptly and move the examination to a conclusion before the extension expires naturally.
- Engage the IRS Appeals Office. If you disagree with the examiner’s proposed adjustments, requesting a conference with the IRS Independent Office of Appeals is a formal right that can sometimes produce a better result.
- Prepare for a potential Notice of Deficiency. If the IRS issues a Notice of Deficiency, you have 90 days to petition the Tax Court without prepaying the disputed tax. Missing that window is a very costly mistake.
- Explore tax debt relief programs proactively. If you expect to owe additional tax when the audit closes, start reviewing options now rather than waiting for the bill to arrive. An overview of IRS resolution programs can help you understand what may be available based on your financial situation.
How This Ruling Connects to Your Broader Tax Debt Situation
The Fine case is fundamentally about the IRS’s window to assess tax. But once tax is assessed, a separate and equally important clock starts running: the IRS generally has 10 years from the date of assessment to collect it. That means an assessment that results from a resolved audit can follow you for a decade if left unaddressed.
Tax debt relief programs exist to help taxpayers resolve what they owe in a structured, legally binding way. The IRS offers several options, from installment agreements to Currently Not Collectible status to the Offer in Compromise program, depending on your income, assets, and the nature of your liability. Qualifying for these programs requires navigating IRS rules accurately, and an audit that results in a large assessment makes that navigation more complex, not less.
The Fine ruling is a reminder that IRS procedure has very little room for assumptions. A form you thought was cancelable is not. A deadline you thought you could restart may have already closed. Getting qualified help early, especially when an open audit year is on the table, is the single most effective step you can take to protect yourself and your finances.
Frequently Asked Questions
Can I refuse to sign Form 872 when the IRS asks me to extend my audit?
Yes. Signing Form 872 is voluntary. Under IRC Section 6501(c)(4)(B), the IRS is legally required to inform you of your right to refuse. If you refuse, the IRS will typically issue a Notice of Deficiency based on what it has found so far, and you will have 90 days to petition the Tax Court without paying the disputed amount first. Refusing may speed up the process but can also result in a less favorable outcome if the audit is not complete. A tax professional can help you weigh this decision based on your specific facts.
What is the difference between Form 872 and Form 872-A?
Form 872 is a fixed-date consent: it extends the IRS’s time to assess tax until a specific agreed-upon calendar date, after which it expires automatically. Form 872-A is an open-ended consent that has no set expiration date. A Form 872-A stays in effect until the IRS or the taxpayer sends a Form 872-T terminating it, or until the IRS issues a Notice of Deficiency. After the Fine v. Commissioner ruling, it is now settled law that Form 872-T cannot be used to terminate a fixed-date Form 872, only an open-ended Form 872-A.
What did the Tax Court decide in Fine v. Commissioner?
In Fine v. Commissioner, 167 T.C. No. 13 (2026), the Tax Court ruled in a precedential opinion that a taxpayer who signs a fixed-date Form 872 cannot use Form 872-T to terminate that extension before its stated expiration date. The court held that Form 872-T applies exclusively to open-ended extensions under Form 872-A. As a result, the IRS Notices of Deficiency issued in that case were timely, and the taxpayers’ statute of limitations defense was rejected. This ruling is binding precedent in the Tax Court going forward.
What happens when the IRS issues a Notice of Deficiency during my open extension year?
A Notice of Deficiency, sometimes called a “90-day letter,” tells you the IRS believes you owe additional tax. You have 90 days from the date of the notice to file a petition with the U.S. Tax Court to dispute the amount without paying it first. If you miss the 90-day window, the IRS will assess the tax and you lose the right to challenge the amount in Tax Court without first paying it. If the assessed amount is more than you can pay at once, you may be eligible for tax debt relief programs such as an installment agreement, an Offer in Compromise, or Currently Not Collectible status.
Does signing a Form 872 mean the IRS thinks I owe more tax?
No. A Form 872 only extends the time the IRS has to complete its review and make an assessment. It is not an admission of liability, and it does not concede that you owe anything. Signing simply means both parties have agreed to allow additional time for the audit to proceed. You retain all your substantive defenses and all your appeal rights. Many audits that involve an extension ultimately result in no additional tax owed.
If I owe tax after an audit closes, what tax debt relief options are available to me?
Several IRS programs may be available depending on your financial situation. An installment agreement lets you pay over time in monthly amounts. An Offer in Compromise may allow you to settle the debt for less than the full amount if you meet specific financial criteria. Currently Not Collectible status can temporarily pause IRS collection if you cannot afford basic living expenses and tax payments at the same time. Penalty abatement programs may also reduce what you owe. A qualified tax debt relief professional can evaluate your eligibility and help you pursue the best path forward.
