The statute of limitations and Appeals: the 365-day rule, statute extensions, and what happens when time runs short

The 365-day rule

IRM 8.21.3.2.1: “Appeals will not accept a proposed deficiency case if the number of days remaining on the Assessment Statute Expiration Date (ASED) for a new receipt is less than 365 days”. Estate tax cases and IRC 6206 excessive claim cases need 270 days. The ATE verifies the statute within 45 calendar days of receiving the case, a time frame the IRM says cannot be extended (IRM 8.21.3.2.1; IRM 8.2.1.4).

Examination works backward from that rule. IRM 4.8.2 tells Technical Services that the statute must have “at least 365 days remaining when the case arrives in Appeals. Therefore, there must be 395 days remaining on the statute when received in TS to allow sufficient processing time.” On a three-year statute (IRC 6501), that means an unagreed case reaching Technical Services with less than about 13 months (395 days) left will generally come with a request to sign Form 872 if the client wants a non-docketed Appeals review.

Publication 5 explains the consequence to taxpayers: the IRS will ask for an extension if needed, and “If you choose not to extend the date, Appeals will not accept your case.” The alternative is a notice of deficiency and a Tax Court petition, after which the case normally reaches Appeals in docketed status anyway (Tax Court petitions).

What the Appeals Officer checks at verification

IRM 8.21.3.2.1 says that verifying the statute on Appeals' database signifies the ATE has reviewed the source documents and IDRS and done any needed research, covering the original statute and every extension. Points the ATE is told to check, and that a representative can check in parallel:

• Special consents. If a period is extended by an open-ended Form 872-A or 872-O and the case has been transferred, the ATE mails Form 872-U, which changes the IRS address for sending a notice terminating the special consent.
• Substitute for return periods. The ATE requests a transcript every six months, because a return filed by the taxpayer starts a live statute from the date it is received.
• Docketed cases. The ATE confirms that the non-petitioning spouse and any non-petitioned years have been assessed.
• Doubt. If the correct date is uncertain, the earliest possible date is entered (IRM 8.21.3.2.1.1).

Cases returned for new issues or information

When a taxpayer raises a new issue or argument or provides information the examiner has not considered, Appeals can return the case to Compliance only if at least 210 days remain on the ASED when Compliance receives it, and “180 days must remain on the ASED for Appeals to accept the case back from Compliance after their consideration of the new issue, new argument or new information.” (IRM 8.21.3.2.1).

If less than 210 days would remain, the ATE asks for a consent. If the taxpayer will not sign, the ATE tells the taxpayer the new information cannot be considered because the originating function has not reviewed it, proceeds without it, and protects the statute if there is no settlement (IRM 8.6.1.7.5). The IRM tells the ATE to make sure any consent leaves enough time for Examination to finish and return the case. Giving the examiner everything before the case goes to Appeals avoids this problem.

How Appeals protects a short statute

The statute is protected in three ways: assessing an agreed deficiency or overassessment, securing a consent, or issuing a notice of deficiency (IRM 8.21.3.2.3). The IRM's timeline:

ATEs run a monthly 180-day statute report, and managers follow up on cases with 45 days or less left (IRM 8.21.3.2.2). A consent that arrives while the notice is being prepared stops the work request. In practice, a representative who wants the case to stay in non-docketed Appeals should return the consent promptly after Letter 967 arrives.

Consents: forms, rights and scope

IRC 6501(c)(4)(A) allows the IRS and the taxpayer to extend the assessment period by written agreement before it expires, and later agreements can extend it again before the extended date. Section 6501(c)(4)(B) requires notice of the taxpayer's rights each time: “The Secretary shall notify the taxpayer of the taxpayer’s right to refuse to extend the period of limitations, or to limit such extension to particular issues or to a particular period of time, on each occasion when the taxpayer is requested to provide such consent.” Appeals satisfies this with Letter 967, a consent form containing the notice, and Publication 1035, sent to the taxpayer and to the representative (IRM 8.21.3.2.3.3).

The IRM recognizes that consents are negotiated:

• “Once you determine that a consent is needed, every effort should be made to obtain at least a six-month extension of the statutory period.”
• If the taxpayer offers a shorter extension than Appeals needs, “Appeals is not compelled to agree to such period.”
• “Both the taxpayer and Appeals have the right to determine what they will agree to in the consent.” (IRM 8.21.3.2.3)

Options include a fixed-date Form 872, an open-ended Form 872-A, and a restricted consent limited to particular issues (IRM 8.21.3.2.3.3 points to IRM 25.6.22 for each). The “kind of tax” line matters: the IRM's example is a Form 1040 with an IRA issue, where a consent for income tax only could let a chapter 43 excise tax expire, so it should read “income and excise.” On a joint return, Appeals must receive a consent signed by both spouses or one from each (IRM 8.6.1.4.6). For the forms themselves, see Form 872 statute extensions.

A consent also affects refunds. Under IRC 6511(c), a claim filed within six months after an extension agreement ends is timely, subject to the amount limits described in IRM 8.7.7.3.2.

Estate tax: no extension possible

“Statute dates on estate tax cases can't be extended by consent under any circumstance”, which is why Appeals requires 270 days and starts the notice of deficiency at 90 days if no settlement is reached (IRM 8.21.3.2.3.2; IRC 6501(c)(4)(A) excludes the chapter 11 estate tax). Estate representatives should expect Appeals to issue a notice even when talks are going well, unless settlement is imminent and the manager allows more time.

Docketed cases

Publication 5: “Note that docketed U.S. Tax Court cases do not have the statute of limitation concerns that non-docketed cases do.” After a notice of deficiency is mailed, the assessment period is suspended while assessment is barred and, once a petition is docketed, until the Tax Court's decision is final, plus 60 days (IRC 6503(a)). That is why a client who will not sign Form 872 still gets an Appeals hearing through the Tax Court route: the docketed case goes to Appeals under Rev. Proc. 2016-22 with no statute pressure. The trade-offs are the filing, the litigation track running in parallel, and the fixed timetable for returning the case to Counsel.

Refund claims and suit deadlines in Appeals

Statute rules work differently in refund cases. “The Service does not secure consents to extend the period for assessment (ASED) in cases involving claims or overassessments, unless Compliance has proposed a deficiency and final disposition could result in a deficiency or additional tax.” (IRM 8.7.7.3.2). What matters instead is the two-year period to sue after a notice of claim disallowance (IRC 6532(a)(1)), which Appeals consideration does not extend. It can be extended only by written agreement on Form 907, executed before the period expires, and the IRM lists satisfactory reasons such as reconsideration that depends on a pending court decision (IRM 8.7.7.3.3). A representative signing Form 907 needs specific authority in the Form 2848. See refund suits.
