Thurston County Tax Deadline Extended for Late Filers

The Internal Revenue Service has provided extra time to some Washington taxpayers after severe winter storms. Affected residents and businesses in designated counties can file and pay later than the normal deadline.

Who qualifies for relief

The IRS relief covers people hit by severe storms, straight-line winds, flooding, landslides and mudslides. The emergency period began in early December.

New filing and payment dates

For most Washington taxpayers, the 2025 federal filing deadline remains April 15. Taxpayers in the qualifying counties now have until May 1 to file returns and make payments.

Eligible filers also have until May 1 to make 2025 contributions to IRAs and health savings accounts. The IRS announced the extension to ease strain on disaster-affected households.

What late filers and other taxpayers should do

Late filers in affected counties may use the extended deadline. Those outside the designated areas should meet the April 15 payment date to avoid penalties and interest.

You can request a six-month extension to file. However, you must pay any tax owed by April 15 to prevent penalties.

Local impacts and estimated damages

Severe storms hit much of Western Washington over the winter. Gov. Bob Ferguson gave a preliminary damage estimate in February of $182.3 million from December floods.

Parts of East Pierce County were especially hard hit. South Prairie, Wilkeson, Orting, and Sumner experienced notable flooding.

Thurston County did not report major storm impacts. Still, some residents may qualify for disaster tax relief if affected.
