Tax Day is Wednesday, but for Washington residents in areas affected by storms, flooding and landslides in December 2025, the Internal Revenue Service is offering an extended deadline.
Taxpayers who live in or have a business in King, Pierce, Skagit, Snohomish, Benton, Chelan, Clallam, Grays Harbor, Jefferson, Kittitas, Lewis, Mason, Thurston, Wahkiakum, Whatcom or Yakima counties have until May 1 to file federal and business tax returns and make payments, the IRS said.
The IRS identifies taxpayers in the covered disaster area and applies the extension automatically.
Western Washington has had a rough go of it in terms of weather in the last few months, enduring atmospheric rivers that brought flooding, windstorms and blizzards that caused power outages, and landslides that blocked roadways, to name just a few impacts.
The deadline extension applies to individual income tax returns, 2025 contributions to IRAs and health savings accounts, tax payments, and quarterly payroll and certain excise tax returns, the IRS said.
If a taxpayer in the area affected by these disasters receives a late filing or late payment penalty notice from the IRS that doesn’t reflect the extension, they should call the telephone number on the notice to have the IRS lift the penalty.
People who live in or have businesses outside of the coverage area but are affected by the flooding can still request relief by calling IRS special services at 866-562-5227.
Taxpayers in the disaster coverage area can also claim disaster-related losses on their federal income tax return until Oct. 15 and deduct personal property losses that aren’t covered by insurance or other reimbursements, the IRS said.
