What is the final date to file federal income taxes?

The final date to file federal income taxes in the United States is typically April 15. However, if this date falls on a weekend or a holiday, the deadline may be extended to the next business day. For 2023, the deadline is April 18 due to Emancipation Day. Taxpayers can also request an extension, allowing them to file by October 15, but any taxes owed are still due by the original deadline.
