Taxpayers living and working abroad must file their 2024 federal income tax return and pay any tax due by Monday, June 16. The deadline applies to both U.S. citizens and resident aliens abroad, including those with dual citizenship.

Taxpayers can request an automatic extension to Oct. 15, 2025, if they can’t file by the June 16 deadline. However, an extension of time to file is not an extension to pay and interest will apply to any 2024 tax payments received after April 15, 2025.
