Federal Tax Extension Deadline Approaches: What Taxpayers Need to Know
Millions of Americans who filed for an extension have until October 15 to submit their tax returns.
Taxpayers who requested a federal tax extension have until October 15 to file their returns. This extended deadline provides an additional six months beyond the initial April 15 tax day for individuals to complete their paperwork.
According to the IRS, more than 20 million taxpayers are anticipated to file their tax returns by this extended due date. It is important for taxpayers to remember that the extension applies only to the filing deadline, not to the payment of taxes owed. Any federal taxes due were still expected by the original April 15 deadline.
"Filing over the summer helps taxpayers avoid the fall rush and gives them more time to resolve issues or arrange payments, if needed," the IRS stated in a release. "To avoid or minimize penalties and interest, taxpayers should estimate their total tax liability, subtract any payments already made, and pay the remaining balance by the deadline."
Failure to meet the October 15 deadline can result in penalties. The IRS levies two primary penalties: failure to file and failure to pay. The failure-to-file penalty is generally 5% of the unpaid tax for each month or partial month that a return is late, up to a maximum of 25%. The failure-to-pay penalty is typically 0.5% of the unpaid tax for each month or partial month, also capped at 25%, though rates can vary.
If a taxpayer owes taxes and misses the extended October deadline, they could face both penalties. For individuals, this means accumulating up to 5% of the tax due per month, with a total maximum of 25%. Additionally, the IRS charges interest on any unpaid penalties.
The failure-to-pay penalty begins to accrue after the original April 15 deadline. The IRS will issue a notice to individuals who incur a penalty.
Taxpayers with an adjusted gross income of $89,000 or less for 2025 can file their taxes for free using IRS Free File. Those with higher incomes will need to use a third-party tax preparation service.
Electronically filed tax returns submitted by the October 15 deadline are typically processed within approximately 21 days. Returns filed by mail may take six weeks or longer.
An additional grace period is available for taxpayers who are located outside the United States. These individuals can request a further two-month extension, moving their deadline to December 15. To qualify for this extension, taxpayers must submit a letter to the IRS explaining their need for additional time.
