A New Federal Law Fixed a Hidden Trap That Denied Refunds to Disaster Victims: What the Disaster Deadlines Act Changed

A federal law signed on December 26, 2025 fixed a problem that had quietly stripped refund rights from disaster victims for years. If you lived or worked in a federally declared disaster area and relied on an IRS filing extension, you may have lost money you were legally owed, without ever knowing it. That trap is now closed, and if you have unfiled returns or unclaimed refunds tied to a disaster period, this change could matter to you.

The Problem Nobody Warned You About

When a major disaster hits, such as a hurricane, wildfire, or flood, the federal government issues a disaster declaration. The IRS then postpones filing and payment deadlines for people in the affected areas, giving them extra time to get their taxes in order. That part of the system worked as intended.

The trap was hidden inside the rules about refunds. Under IRC Section 6511, taxpayers must file credit and refund claims within three years from the date their return was filed, or within two years from the date the tax was paid. On top of that filing deadline, there is a second rule called the lookback period. The tax refund amount is generally limited to federal taxes paid within the three years preceding the tax refund claim, plus any extension of the federal tax return deadline.

The critical word there is “extension.” A standard extension, the kind you request on Form 4868, counted toward expanding that window. But a disaster postponement was legally different. Under the law in effect prior to this act, the postponement of the federal tax return deadline was not an extension for purposes of the lookback period. As a result, certain tax payments, such as amounts withheld from a paycheck, made before the federal tax return was filed could fall outside the lookback period and become non-refundable.

In plain terms: the IRS told you it was okay to file late because of the disaster. You filed late. But because the clock on the lookback period kept running during your postponement, some or all of the taxes you overpaid were no longer recoverable by the time your return came in. You did everything right, and you still lost your refund.

How the Math Actually Hurt People

Here is a concrete example of how the old rule worked against disaster victims. Say you had taxes withheld from every paycheck throughout a given year. Under tax law, those withheld amounts are treated as paid on April 15 of the following year. The IRS grants your area a disaster postponement, pushing your filing deadline several months out. You file your return using the postponed deadline.

Now suppose more than three years pass between that original April 15 date and the date you file a refund claim. Amounts paid via withholding or estimated taxes, which are deemed paid on the original April 15 deadline, could fall outside the recognizable refund window if a return was filed during the disaster postponement period but after the three-year anniversary of the original due date. The IRS could, and did, deny refunds on that basis.

This was not a technicality affecting a handful of people. The Taxpayer Advocate Service had flagged this as a serious and recurring problem, particularly after large-scale disasters where postponements stretched across many months.

What the New Law Actually Changed

President Trump signed the Disaster Related Extension of Deadlines Act (H.R. 1491) into law, providing additional procedural protections for taxpayers affected by federally declared disasters. It is now Public Law 119-64, signed December 26, 2025.

The act passed Congress with unanimous support and makes two concrete changes.

Change 1: Disaster postponements now count as extensions for refund purposes

The act amends IRC Section 7508A to provide that any filing period extension resulting from a federally declared disaster is also treated as an extension of time for filing a claim for credit or refund. In other words, the extra time the IRS gave you because of the disaster now also expands the window of tax payments that are eligible to be refunded. The lookback period stretches to match your postponed deadline, just as it would have if you had filed a standard extension on Form 4868.

H.R. 1491 corrects this issue by allowing the disaster postponement period to be included when calculating the refund lookback window, preserving refund eligibility in affected situations.

Change 2: The IRS can no longer send premature collection notices during a postponement

The old law created a second problem that compounded the stress of disaster recovery. Prior to the enactment of the Disaster Related Extension of Deadlines Act, the IRS took the position that disaster postponement did not affect the deadline for issuing a collection notice demanding payment. The result was that taxpayers received collection notices demanding payment and warning of interest and penalties before the postponed payment deadline provided by the disaster relief postponement.

In 2023 alone, the IRS sent over a million of these notices erroneously informing taxpayers in disaster areas that their tax was due prior to the postponed deadline. Although the IRS later sent follow-up explanations with additional notices attempting to explain the situation, the mixed messages only added to the confusion.

The new law ends that practice. The act prohibits the IRS from mailing a payment due notice to disaster victims until 60 days after the disaster postponement period ends. If you are in a disaster area and your payment deadline has been pushed back, the IRS must now wait until your actual extended due date has passed before it can demand payment.

Who This Applies To, and What Time Periods Are Involved

The law aligns the deadline for claiming prior-year refunds or credits with the extended filing period granted to taxpayers impacted by natural disasters. The change applies going forward to disasters declared after the law’s enactment. If you were in a federally declared disaster area, received an IRS filing postponement, and either have not yet filed or are wondering whether you may have a refund claim, this law may be relevant to your situation.

There is also a separate, active legal development affecting taxpayers who were in the COVID-19 disaster period. Courts have interpreted Section 7508A to mean that certain deadlines were suspended from January 20, 2020 through July 10, 2023. For many taxpayers, critical deadlines to preserve potential refund claims arising from the COVID-19 disaster period may begin to expire in mid-2026. Refund claims are generally required to be filed within three years from the time the return was filed or two years from the time the tax was paid, whichever is later, and taxpayers may have materially stronger refund positions than previously understood. Time on those COVID-era claims may be running short, so if you believe you have unfiled returns or overpaid taxes from 2019 through 2022, this is not the moment to wait.

What You Should Do If This Affects You

This law does not automatically send you a check. It removes a legal barrier that previously prevented disaster-area taxpayers from even being eligible to claim certain refunds. To actually recover money you may be owed, you need to file the right forms with the IRS, meet any remaining deadlines, and understand how the lookback rules apply to your specific situation.

If any of the following apply to you, it is worth looking into this carefully:

• You lived or ran a business in a federally declared disaster area and used an IRS postponement to file late.
• You have unfiled tax returns for years covered by a disaster postponement.
• You had taxes withheld from wages or made estimated tax payments during a year when a disaster postponement was in effect.
• You received confusing IRS collection notices during a period when your deadline had been postponed.
• You believe you overpaid taxes for any year between 2019 and 2022 and have not yet filed a refund claim.
