The Feb. 2, 2026, deadline applies to individual income tax returns and payments normally due on or after June 12, 2025. The February deadline also applies to 2025 contributions to IRAs and health savings accounts for eligible taxpayers and to estimated tax payments normally due on June 16 and Sept. 15, 2025 and Jan. 15, 2026.
Penalties on payroll and excise tax deposits due on or after June 12, 2025, and before June 27, 2025, will be abated if the tax deposits were made by June 27.
Payments for returns on a filing extension are ineligible for additional time to pay, as filing extensions only apply to the filing of the return and not to payments.

Affected taxpayers who reside or have a business located outside the covered disaster area should call the IRS Special Services number at (866) 562-5227 to request this relief.

Affected taxpayers in a federally declared disaster area have the option of claiming disaster-related casualty losses on their federal income tax return for either the year in which the event occurred, or the prior year — in this instance, the 2025 return (normally filed next year), or the return for the prior year (the 2024 return filed this year). Taxpayers have up to six months after the due date of the taxpayer's federal income tax return for the disaster year (without regard to any extension of time to file) — to make the election. For individual taxpayers, this means Oct. 15, 2026.
Affected taxpayers claiming the disaster loss on their return should put the FEMA disaster declaration number, 3624-EM, on any return.
