For most Americans, federal income tax returns are due April 15 of the year following the tax year. But in disaster-affected areas, the IRS usually extends tax deadlines to support the people affected. These extensions automatically apply to eligible individuals and businesses in federally declared disaster zones.

Using Extra Time Wisely
An extension to file doesn’t always mean an extension to pay unless specifically stated in the IRS relief notice for the relevant state. Anyone in an affected area should confirm their eligibility before assuming it applies to them, and double-check dates and payment schedules.
While the extra time can be essential for anyone dealing with a disaster, it can be helpful in giving people a chance to review deductions and confirm eligibility for credits. As affected taxpayers can make IRA or HSA contributions up to the extended deadline under the IRS disaster relief rules, it can also help maximize retirement savings. Filing early within the extension window can help speed up refunds and reduce the risk of missed paperwork.
