MILWAUKEE— The Internal Revenue Service is giving thousands of Wisconsin taxpayers more time to file their federal tax returns after severe storms, tornadoes and flooding impacted the state this spring.
The IRS announced Monday that individuals and businesses in 21 federally declared disaster counties now have until Nov. 2, 2026, to file certain federal tax returns and make tax payments.
The extension follows a federal disaster declaration issues by the Federal Emergency Management agency for storms that began April 13.
Eligible counties include Milwaukee, Waukesha, Racine, Kenosha, Washington, Brown, Outagamie, Winnebago, Rock and several others, along with the Oneida Indian Reservation.
The Nov 2. deadline applies to taxpayers whose filing or payment deadline fell between April 13 and Nov. 2. That includes 2025 individual income tax returns originally due April 15, taxpayers who received an extension to file, as well as certain quarterly payroll and excise tax returns.
The IRS also said eligible taxpayers may be able to claim disaster-related casualty losses on either their 2025 or 2026 federal tax return. Those claiming a disaster loss should include FEMA disaster declaration number 4923-DR on their return.
Most eligible taxpayers will receive the filing and payment relief automatically, according to the IRS.
