Most people I talk to about their IRS problem have already built the worst-case scenario in their head. The reality is usually much more manageable. I'm Darrin Mish, and I've been representing taxpayers before the IRS for 32 years. Here's what actually tends to happen.<\/p>\n

<\/p>\n

I'm Darrin Mish. Tampa tax attorney, 32 years in, more than $100 million in IRS debt resolved.<\/strong> What follows isn't theory. It's what I've actually watched work.<\/p>\n

The IRS usually has three years from when you file your return to assess additional tax. That clock ticks whether you know it or not. But sometimes the Service asks you to stop the clock. They send you an irs form 872 statute extension and ask you to sign it, giving them more time to finish an audit or investigate your return. The question you're facing is simple: should you sign it, and what happens if you don't?<\/p>\n

What IRS Form 872 Actually Does<\/h2>\n

Form 872 is titled "Consent to Extend the Time to Assess Tax." It's a bilateral agreement. You agree to let the IRS assess tax beyond the normal three-year statute of limitations set by 26 U.S.C. \u00a7 6501<\/a>, and the IRS agrees to keep working your case instead of rushing to close it. Both parties sign it.<\/p>\n

The normal assessment period starts the day you file your return and runs three years. File on April 15, 2023, and the IRS generally has until April 15, 2026 to assess additional tax. If that date passes without an assessment, the IRS loses the right to bill you for that year. Forever.<\/p>\n

Form 872 pushes that expiration date forward. The extension is mutual. You're not waiving your rights or admitting anything. You're agreeing to a new deadline.<\/p>\n

\"ASED<\/p>\n

Why the IRS Asks for Extensions<\/h3>\n

The Service doesn't request an irs form 872 statute extension because they're lazy. They ask because they need more time to finish the examination and they're running out of runway. Complex audits, international issues, business returns, partnership allocations, cryptocurrency transactions. All take time.<\/p>\n

Sometimes the delay is on their end. Revenue agents get reassigned, cases transfer between offices, or the IRS simply has a backlog. Sometimes it's your delay. You needed three months to gather bank statements, your CPA went on medical leave, or you're still reconstructing records after a flood.<\/p>\n

When the statute is about to expire, the IRS faces a choice: assess tax based on incomplete information (which might be wrong and which you'll appeal), or ask for more time to get it right. IRS procedures for handling consent agreements<\/a> favor accuracy over speed, so the agent sends you Form 872.<\/p>\n

Fixed-Date vs. Open-Ended Extensions<\/h2>\n

Form 872 extends the statute to a specific date. You might agree to extend it by six months, one year, or eighteen months. The form lists the new expiration date clearly. When that date arrives, the extended period ends. The IRS must assess by then or lose the right.<\/p>\n

Form 872-A is different. That's the "Special Consent to Extend the Time to Assess Tax" and it's open-ended. It stays in effect until either you or the IRS terminates it by filing Form 872-T. Signing 872-A gives the Service indefinite time.<\/p>\n

You should almost never sign Form 872-A.<\/strong> There's rarely a good reason to give the IRS unlimited time. Fixed-date extensions using Form 872 give both sides certainty and keep pressure on the IRS to finish.<\/p>\n\n\n\n\n\n\n\n

When You Should Sign<\/h3>\n

Sign the irs form 872 statute extension if you need the time as much as the IRS does. If you're still gathering documents, working with your accountant, or negotiating an audit defense strategy<\/a>, the extension protects you. Without it, the agent might assess tax based on incomplete facts.<\/p>\n

Sign if you're close to a resolution. If you're negotiating an agreed assessment or working toward a settlement that benefits you, giving the IRS another six months to finalize it makes sense. Forcing the statute to expire doesn't make a bad audit result go away if the IRS has enough information to assess before the deadline.<\/p>\n

Sign if refusing would trigger a hasty assessment you'll spend years fighting. Revenue agents don't like letting statutes expire. If you refuse to extend and the deadline is two weeks out, the agent will assess something. It might be more than you actually owe, and you'll fight it in appeals or Tax Court.<\/p>\n

When You Should Refuse to Sign<\/h2>\n

Refuse if the IRS is fishing. If the agent has had two years, full access to your records, and still can't articulate what they think you owe, refusing to extend forces a decision. Either assess based on what they have, or close the case.<\/p>\n

Refuse if the delay is entirely the IRS's fault and there's no legitimate need for more time. If the agent sat on your case for eighteen months, asked for three rounds of identical documents, and now wants another year because they're "still reviewing," you have leverage. The Taxpayer Advocate Service explanation of ASED<\/a> emphasizes that extensions are voluntary agreements, not demands.<\/p>\n

Refuse if you're confident the IRS doesn't have the evidence to sustain the assessment they're proposing. Let the statute run. If they assess anyway, you'll contest it. If they don't, the issue dies.<\/p>\n

Refusing to sign is a strategic decision, not a tantrum.<\/strong> You're telling the IRS to make a call with the time they have left. That can work in your favor or against you, depending on how strong their case is and how much they've already developed.<\/p>\n

\"Decision<\/p>\n

What Happens After You Refuse<\/h3>\n

The agent will escalate. Their manager gets involved. You might get a phone call or a letter explaining why they need the time. If you still refuse, the agent has to choose: close the case with no changes, or issue a notice of deficiency (also called a 90-day letter).<\/p>\n

A notice of deficiency is the IRS's formal proposal of additional tax. You have 90 days to petition Tax Court if you disagree. The notice tolls the statute, meaning the IRS can assess the amount in the notice even if the three-year period expires while your case is in Tax Court. Treasury regulations on exceptions to the limitations period<\/a> govern how this works.<\/p>\n

If the IRS issues the notice, you're in a formal dispute. That's not always bad. Sometimes you want that. You get Tax Court review before paying a dollar, and you force the IRS to prove their case in a neutral forum.<\/p>\n

Partnership and Corporate Extensions<\/h2>\n

Partnerships operate under different rules. The IRS often uses Form 872-P to extend partnership statutes. Changes at the partnership level flow through to the partners, so the Service wants to lock down the partnership audit before individual partners' statutes expire.<\/p>\n

Since 2018, the IRS has used the centralized partnership audit regime under the Bipartisan Budget Act. The partnership representative signs consents on behalf of the entity. Individual partners might not even know the partnership signed an extension. U.S. Tax Court decisions<\/a> have addressed how these consents operate and when they bind individual partners.<\/p>\n

Corporations face similar issues. If you're a shareholder in an S corporation or a member of an LLC taxed as a partnership, check whether the entity signed a statute extension. That extension can extend the time to assess tax on your individual return for items that flow through from the entity.<\/p>\n

Negotiating the Terms<\/h3>\n

The IRS sends you a pre-filled Form 872 with a proposed extension date. You don't have to accept that date. You can negotiate a shorter period. If they want eighteen months and you're willing to give them six, counter-propose. Write the shorter date on the form.<\/p>\n

You can also condition your consent. Some taxpayers agree to extend the statute only for specific issues, not the entire return. If the audit focuses on your home office deduction but the agent starts asking about your rental property, you might agree to extend only the home office issue. The IRS doesn't always accept limited consents, but you can propose them.<\/p>\n

Everything is negotiable until both parties sign.<\/strong> The IRS’s own publication on extending the assessment period<\/a> acknowledges that you can decline or propose modifications. The agent wants your signature, which gives you leverage.<\/p>\n

How Extensions Affect Other Deadlines<\/h2>\n

Extending the assessment statute also extends the IRS's time to file tax liens<\/a> and begin collection. If they assess within the extended period, the ten-year collection statute starts from the assessment date, not from the original return due date.<\/p>\n

Extending the assessment period doesn't extend your time to file a refund claim. If you're owed a refund, you generally have three years from the filing date or two years from the date you paid the tax (whichever is later) to claim it. Signing Form 872 doesn't change that.<\/p>\n

It also doesn't extend your time to amend your return. If you discover an error in your favor, file the amendment within the normal three-year window. Don't assume the extended assessment period gives you more time to claim refunds.<\/p>\n

State Tax Consequences<\/h3>\n

Most states link their audit authority to the federal statute. If you extend the federal assessment period, you might automatically extend your state's period as well. Some states require separate consent forms, but others piggyback on federal extensions.<\/p>\n

Check your state's rules before you sign. If you're under audit in both jurisdictions, coordinate your response. Extending the federal statute while refusing the state extension (or vice versa) can create timing problems.<\/p>\n

\"State<\/p>\n

What Gets Extended and What Doesn't<\/h2>\n

An irs form 872 statute extension extends only the assessment period. It doesn't extend the IRS's time to criminally prosecute tax fraud (that's a separate six-year statute under 26 U.S.C. \u00a7 6531). It doesn't extend the time to file penalties for failure to file or pay<\/a>.<\/p>\n

It extends the time to assess all taxes, interest, and penalties related to the return in question. If you sign a Form 872 for your 2022 tax return, the IRS can assess income tax, self-employment tax, penalties for accuracy-related issues, and interest up to the new extended deadline.<\/p>\n

The extension applies only to the tax year listed on the form. If you're under audit for 2021, 2022, and 2023, you might sign separate Forms 872 for each year with different extension dates. Keep track of which years have been extended and which haven't.<\/p>\n

Tracking Multiple Extensions<\/h3>\n

The IRS can ask for multiple extensions on the same return. You sign Form 872 in March 2026, extending the 2022 statute to September 2026. In August 2026, the agent asks for another extension to March 2027. You can agree or refuse.<\/p>\n

Each extension is a separate agreement. Signing the first one doesn't obligate you to sign the second. As the statute gets extended repeatedly, your leverage increases. The IRS has invested more time, and walking away without assessing becomes harder for them to justify internally.<\/p>\n

Keep a spreadsheet.<\/strong> Track every tax year under examination, the original statute expiration date, each extension you've signed, and the current expiration date. Agents make mistakes. I've seen cases where the IRS thought they had more time than they actually did because someone misread an extension date.<\/p>\n

Oversight and Taxpayer Protections<\/h2>\n

The Treasury Inspector General for Tax Administration (TIGTA) monitors how the IRS requests and handles statute extensions. TIGTA reviews of assessment statute extension practices<\/a> have found that the Service generally follows procedures, but errors happen.<\/p>\n

TIGTA found cases where agents didn't properly notify taxpayers of their right to refuse, didn't explain the consequences clearly, or let statutes expire by mistake. Independent oversight creates accountability, but it doesn't eliminate problems.<\/p>\n

You have the right to refuse any extension request. The IRS must explain why they need more time, but they don't have to convince you. If you refuse, they can't force you to sign. Recent legal reporting on IRS extension practices<\/a> confirms that agents generally comply with legal requirements when soliciting extensions, but the decision remains yours.<\/p>\n

Working With a Tax Attorney<\/h2>\n

Before you sign an irs form 872 statute extension, talk to someone who handles IRS disputes regularly. An attorney can evaluate whether the extension helps or hurts your position. We look at how much the IRS has already developed, what they're likely to assess if you refuse, and whether forcing a decision now benefits you.<\/p>\n

Sometimes we negotiate the extension terms. Sometimes we refuse and prepare for the next stage. Sometimes we agree to extend but use the extra time to prepare a penalty abatement request<\/a> or gather evidence that weakens the IRS's position.<\/p>\n

The extension decision is tactical, not administrative.<\/strong> You're managing a dispute timeline. Experienced representation means you make that decision with full information about the likely outcomes of each choice.<\/p>\n

Thirty-two years in, I've signed hundreds of Forms 872 for clients when it served their interests. I've also refused hundreds when it didn't. The decision depends on the specific facts of your case, the strength of the IRS's position, and what you're trying to accomplish.<\/p>\n

Record Retention and Documentation<\/h2>\n

If you sign a Form 872, keep a copy forever. Attach it to your permanent tax records for that year. If the IRS later claims the statute was still open when it had actually expired, your signed consent form (or lack of one) is the proof.<\/p>\n

If you refuse to sign, document that refusal in writing. Send the agent a letter stating you decline to extend the statute and explaining why if you want to. Keep a copy and proof of delivery. If the case later becomes contentious, you'll want evidence that you clearly communicated your refusal.<\/p>\n

Track all correspondence related to statute extensions. Email chains, certified mail receipts, IRS letters. If a dispute arises about whether the IRS timely assessed tax, these records become critical evidence. The burden is on the IRS to prove they assessed within the limitations period, but you need documentation to challenge their claims effectively.<\/p>\n
