IRS Form 872: how we think about extending the audit clock

The request usually shows up late in an examination, and it rarely looks like much. The revenue agent sends over IRS Form 872, a consent form, with a note asking you or your CPA to sign and return it promptly.

It reads like housekeeping. It's a decision. Signing gives the IRS more time to assess additional tax for the year under audit, and declining sets a different chain of events in motion.

This is a federal rule, and it works the same way in Oklahoma City as it does anywhere else. Owners of closely held Oklahoma and Texas companies, and the CPAs who represent them in exams, are the people who get handed the form. Oklahoma's own assessment clock is a separate subject.

What IRS Form 872 does to the assessment period

Federal law gives the IRS a limited time to assess, which means to formally record a tax liability on its books. The general rule in section 6501 of the Internal Revenue Code is that tax must be assessed "within 3 years after the return was filed." The IRS's public guidance counts those three years from the return's due date, or from the date the IRS received the return if that's later, and calls the last day the Assessment Statute Expiration Date, or ASED.

The same section lets the two sides move that date. If you and the IRS both consent in writing before the period runs out, the tax can be assessed at any time up to the agreed date. A later written agreement, made before the current one lapses, can push it again.

Form 872, titled Consent to Extend the Time to Assess Tax, is a fixed-date consent. It names a date, and IRS Publication 1035 says a fixed-date consent expires on that date unless both sides agree to extend it further. The Treasury regulation adds that an extension takes effect once both parties have signed.

There's also an open-ended version, Form 872-A. According to the publication, it generally keeps the period open until 90 days after either you or the IRS sends the prescribed notice ending the arrangement. The IRS's internal manual lists a Form 872-T, Notice of Termination of Special Consent to Extend the Time to Assess Tax, under its heading for Form 872-A.

Two boundaries before going further. The statute's consent provision carves out the estate tax. And partnerships audited under the centralized partnership audit regime have their own limitations and consent rules, which are outside this article; we wrote about that regime in our piece on partnership audits.

The right to say no is written into the statute

Congress didn't leave your options to custom. The Code says the IRS "shall" notify you of your right "to refuse to extend the period of limitations," or to limit the extension to particular issues or to a particular period of time. It has to do that "on each occasion when the taxpayer is requested to provide such consent."

The agency's public guidance says the same thing in plainer words: "You can negotiate the proposed time extension or refuse to sign the waiver." Publication 1035, the IRS's own explanation of the process, adds that "Under no circumstances will a penalty be charged for not signing the consent" to extend the assessment period.

So every time the form arrives there are three choices on the table: sign it as written, negotiate its terms, or decline. None of them is automatically right.

Why the agent is asking

We'd start by taking the request at face value. In our experience it's rarely a tactic. It's a calendar problem.

Publication 1035 explains that the IRS identifies returns under examination whose assessment period is about to expire and asks for more time. The stated purposes run in both directions. You get time to provide further documentation and to request an appeal, and the IRS gets time to complete the examination properly and make whatever adjustment turns out to be required.

The appeal point matters more than it first appears. Appeals is the IRS's internal administrative review, the office that hears your disagreement with the examiner before anyone goes to court. The publication says the IRS can't offer that review "unless sufficient time remains on the statute of limitations."

Inside the agency, the internal manual puts numbers on the idea. One of the conditions it lists for requesting a consent is a limitation period that will expire within 180 days when there isn't enough time left to finish the examination, and it calls for "at least 365 days" remaining on the statute when Appeals receives a case. The manual instructs IRS employees, and we read it as a description of practice and nothing more.

Three choices, and what each one sets in motion

Signing the consent as presented

An unconditional consent keeps everything where it is and adds time. Publication 1035 describes it as giving the IRS the same assessment authority, and you the same appeal opportunities, that existed under the original period.

That's frequently the sensible answer. If documents are still coming in and you'd want Appeals to hear the issues you can't settle with the agent, a consent is the price of keeping the dispute in a setting far less formal than a courtroom.

The cost is scope. An unconditional consent, in the publication's words, "does not limit the examination or appeal activities to specific issues," and during the added time the IRS "may examine any issues relevant to your tax return."

You may think you're buying time for one disputed deduction. The form keeps the whole return open.

Time carries its own cost as well. The publication says interest generally keeps accruing until the balance is paid, including while a case sits in Appeals, and it notes that "a cash deposit may be made to stop the accrual of interest."

Negotiating the date or the issues

The statute names two levers: the period and the issues. The period is the easier conversation. If the proposed date is a year out and the remaining work looks like a few months, asking for a shorter extension is an ordinary request, and a fixed-date consent can be extended again if both sides later agree.

A restricted consent is the second lever. It limits further examination or appeal activity to the issues it names, which makes it the more valuable protection and the harder one to get. Publication 1035 says the IRS generally won't enter into one unless all of these conditions exist:

• the number of unresolved issues doesn't make a restricted consent impractical;
• the scope of the restrictions is clearly and accurately described for every unresolved issue;
• the issues the restricted consent doesn't cover are agreed, with provision made for assessing any deficiency, or scheduling any refund or credit, on them;
• the appropriate IRS official approves using a restricted consent; and
• IRS Counsel approves the terms and language before the parties sign.

We read that list as a negotiating map. A restricted consent is realistic when the audit has narrowed to one or two well-defined disputes and everything else is resolved. Because Counsel has to approve the wording, our practice is to raise it well before the date, not in the week the form is due.

Declining

Refusing is a lawful choice with no penalty attached. It isn't a quiet one.

For income tax, the publication says the IRS will issue a notice of deficiency, the formal letter that proposes additional tax and opens the way to the U.S. Tax Court. "The notice is not an assessment of tax." It does start a clock: under the Code you have 90 days after the notice is mailed, or 150 days if it's addressed to a person outside the United States, to file a petition.

If you don't petition, the IRS can assess the amount in the notice. If you do, the Code generally bars assessment until the Tax Court's decision becomes final.

Either way, the assessment period stops running in the meantime. The statute suspends it for as long as the IRS is prohibited from assessing, and for 60 days after that.

Owners often miss what follows. Declining to sign doesn't run out the clock, because in the ordinary case, as we've seen it, the notice goes out before the date arrives.

What refusal changes is the forum and the record. A deficiency notice issued because time ran short is, in our experience, written on the information in the agent's file that day, which may not include the documents you were still gathering. The conversation in exam is over.

The publication describes another path too: pay the disputed amount and file a refund claim, and if the claim is disallowed, sue in a U.S. District Court or the U.S. Court of Federal Claims. For certain employment and excise taxes, it says, the IRS will normally assess the tax, and the route to court runs through payment and a refund claim.

One fear can be set aside. Publication 1035 says jeopardy assessments, the immediate assessments the IRS makes when collection itself is at risk, aren't made merely because the period is about to expire or because you declined to consent, unless collection really is in jeopardy.

There are situations where declining is the stronger posture. When the file is complete and more time would only add interest, a deficiency notice gets the dispute in front of a judge sooner.

The questions we ask before choosing

Take a hypothetical. An Oklahoma City distribution company filed its corporate return on time, and with four months left before the three-year date the agent has proposed adjustments on two issues. The company agrees with one, its controller is still assembling records on the other, and the agent sends a Form 872 that moves the date out 12 months.

Nothing in that invented sketch dictates an answer. It does show which facts drive one.

The state of the file

We want to know first whether the record is complete today. If your best documents aren't in yet, time helps you more than it helps the IRS.

The value of Appeals

Some disputes are factual and turn on substantiation. Others turn on a legal position that, in our experience, gets a fuller hearing from an Appeals officer than from an examiner. If the second description fits, keeping the path open to IRS Appeals after the audit usually argues for signing something.

What else is on the return

An honest inventory matters here. If there are positions on the return the agent hasn't examined, an unrestricted consent keeps them within reach for the whole extension.

Whether three years is really the number

The three-year rule has exceptions. The Code gives the IRS six years when a taxpayer omits gross income exceeding 25 percent of the gross income stated in the return, and it sets no limit at all for a false or fraudulent return filed with intent to evade tax or where no return was filed. When the IRS has a credible argument that a longer period applies, refusing a consent buys less than it seems to.

The refund side

Extensions can help the taxpayer in a way few people notice. Under section 6511(c) of the Code, when a consent is signed while the period for claiming a refund is still open, that refund period "shall not expire prior to 6 months after" the extended assessment period ends. A separate paragraph caps the amount that can be refunded on such a claim, so the benefit is real but bounded.

Who has to sign

A consent signed by the wrong person is a problem for everyone. The IRS's manual says a consent is to be signed "in the same manner as the return that was filed," and for a joint return it treats each spouse as having a separate statute of limitations, so each spouse must sign. For a company, who has authority to sign is a question to settle before the form goes back.

How the request tends to arrive

None of the publications describe the moment itself. In our experience the form usually reaches the owner secondhand, through the CPA handling the exam, with a short turnaround and a cordial note. It gets signed as routine because it has always been signed as routine.

We'd slow that down by a day. Read the form number first: a Form 872 has a date you can calendar, while a Form 872-A has none and stays open until somebody ends it. Then calendar the new date, along with the refund-claim window that trails it.

CPAs have their own item to check. The IRS's manual says a representative holding a valid power of attorney may execute a consent, and it has the approving official verify that the document is specific in authorizing the representative to sign consents.

Signing isn't the mistake. What bothers us about the routine signature is that the date and the issues were negotiable, and nobody asked.

Where Oklahoma fits

Everything above is federal. A Form 872 is an agreement with the IRS about federal tax.

This article doesn't address the Oklahoma Tax Commission's own period for assessing Oklahoma income tax, or how a federal extension or a federal audit adjustment interacts with it. We didn't open Oklahoma authorities for this piece and we won't guess. Our separate article on the Oklahoma income tax statute of limitations is the place to start.

If a consent request has landed on your desk, or on your CPA's, the time to talk it through is before the signature. You can reach us through the contact page or at our Oklahoma City office. A conversation at that stage almost always costs less than repairing the choice afterward.
