2025 Tax Return Deadlines: States With Extended Filing Dates

Every year, disaster strikes somewhere. However, the federal government offers various forms of relief. They recognize not everyone is as capable of preparing and filing tax returns as easily as usual, and the IRS extends filing deadlines to help.

Key takeaways

• IRS disaster-related deadline extensions are becoming more and more common, and their details are increasingly specific and complex.
• You now need to verify your personal eligibility beyond geography. Qualifications could depend on factors like where your records are, whether you’re assisting with relief efforts, or personally impacted while visiting the area. The IRS’s specific relief notice for each disaster is the only sure source.
• Extended deadlines create opportunities, not excuses. Better tax planning can result from tragic events and the government’s relief.

Why the IRS allows state-wide deadline extensions

The IRS has the authority to issue area-specific deadline extensions, and these typically stem from FEMA-declared federal disasters. When this occurs, the IRS releases corresponding relief notices for the affected areas. 

Some deadline extensions go beyond tax return filings and include grace on payments, penalties, and even additional extension requests, too. That’s why it’s important to understand which provisions apply for you. Here’s an example of how these bulletins appear when they’re posted online.

The IRS also hosts an informational hub where taxpayers can access real time updates, including: 

• A list of current and recent disasters, organized by affected states 
• Links to the news releases describing who the IRS qualifies as “affected”, which deadlines have been extended, and the new due dates 
• Details from FEMA about the incident, such as its start date, name, and disaster number
• Which counties, zip codes, and parishes qualify
• The original deadlines alongside the new extended due dates
• A breakdown of which tax filings and payments are postponed (like individual income taxes, estimated tax payments, payroll tax, IRA and HSA contributions, fees, etc.)
• Links to forms and other informational resources
• FAQs to answer common inquiries

States where taxpayers can file federal tax returns later than April 15, 2026

Some deadline extensions apply to already-extended deadlines, while others apply only to corporations. Many deadline extensions are short-lived, which means they were announced in 2025, and have deadlines that have already passed. Check out this easy resource to start your search, which includes links to the agency’s official guidance.
