The IRS is encouraging taxpayers who received filing extensions to use IRS Free File to submit their 2025 federal tax returns before the 15 October 2026 deadline, with free guided tax preparation available to eligible taxpayers. 

The US Internal Revenue Service (IRS) has issued a release urging taxpayers who received filing extensions to use IRS Free File to submit their 2025 federal tax returns as soon as possible, ahead of the 15 October 2026 deadline.

IRS Free File remains available through 15 October 2026 and offers free guided tax preparation for taxpayers with an adjusted gross income of USD 89,000 or less in 2025. Taxpayers can prepare and e-file federal returns securely with IRS trusted partners at no cost.

Taxpayers with income above the threshold can use Free File Fillable Forms if they are comfortable preparing their own tax returns.

Filing over the summer helps taxpayers avoid the fall rush and gives them more time to resolve issues or arrange payments, if needed. An extension gives taxpayers more time to file but not more time to pay. Taxpayers who owe tax should pay as much as they can as soon as possible to limit penalties and interest.

IRS Free File provides a secure, convenient way to file from home. The guided software includes step-by-step instructions and built-in error checks, and some trusted partners also offer free state tax return preparation and filing for eligible taxpayers.

Taxpayers who are due a refund can get their refund faster by filing electronically and choosing direct deposit.
