Tax Day 2024: Federal Income Tax Returns Due April 15, Extended Deadline October 15

Samantha Miller

In the United States, the last day to file a federal income tax report for 2024 is April 15, 2024. People in Maine and Massachusetts, on the other hand, have until Tuesday, April 17, 2024, because those days are state holidays.

Taxpayers who asked for an extra six months to file have until October 15, 2024, to do so. In 2024, the tax due dates are likely to be April 15, 2024, June 17, 2024, September 16, 2024, and January 15, 2025.

What Happens If You File Your Taxes Beyond the Deadline in 2024?

In 2024, the penalties for filing taxes late are as follows:

  1. Failure to File a Tax Return: The late filing penalty is 5% of your unpaid taxes for each month your return is late, up to a maximum of 25%. If your tax return is not filed within 60 days of the due date, you’ll be charged a minimum late-filing fee of $510 or 100% of taxes owed, whichever is lower.
  2. Failure to Pay Taxes on Time: The late payment penalty is 0.5% of the additional tax owed amount for every month (or fraction thereof) the owed tax remains unpaid, up to a maximum of 25%.

Here are some examples of how the penalties would apply:

  • Scenario 1: You don’t file your return by the April 15, 2024 deadline and you owe the IRS $1,000. If you file an extension on or before April 15, 2024, and pay your $1,000 bill on April 25 (10 days late), your penalty would be $5 (the 0.5% late-payment penalty applied to $1,000), plus another dollar or so for the interest.
  • Scenario 2: You don’t file an extension, and you file your return on April 25 (10 days late) along with your $1,000 payment. Your penalty would be $50 (the 4.5% late-filing penalty applied to $1,000).

Please note that the IRS applies late penalties and interest on a case-by-case basis, so the exact amount of the penalty may vary depending on your specific situation.

When Do Americans Residing Overseas Have to File Their Taxes?

Americans who live outside of the United States must file their taxes by June 17, 2024. US citizens living abroad get an extra two months to file their taxes after this date, on top of the regular April 15 due for taxpayers in the US.

It’s important to remember, though, that even though the deadline for filing has been pushed back, any taxes that are still due by April 15 must be paid in order to avoid interest charges. You can ask for another delay if you need more time.
