Staying on top of US tax deadlines is essential for American citizens, residents, and non-resident aliens whether you live in the United States or abroad.
Important tax dates include estimated tax payments due dates, federal and state return deadlines, and deadlines for extension requests.
If you live abroad, you automatically receive a two-month extension to file your federal return – until June 16, 2025. However, any taxes owed are still due by April 15. Need more time? You can request an additional extension to file your return until October 15, 2025 and, if necessary, apply for a final extension to December 15, 2025.

Regular US tax due date
Tax Day is usually April 15, unless it falls on a weekend or holiday. In 2025, the deadline stays April 15. If you need more time, you can file Form 4868 to extend your filing deadline to October 15, 2025.
The tax filing threshold for US citizens abroad generally depends on income level and filing status. For example, if you are single, you must file if your income exceeds $14,600 for the 2024 tax year.
Tax filing deadline for US citizens and green card holders abroad
If you live abroad, the Internal Revenue Service (IRS) gives you an automatic two-month extension – moving your 2024 tax deadline to June 16, 2025.
NOTE!
- Even with this extension, any taxes owed are still due by April 15, 2025. Interest and possible penalties start accruing on unpaid balances from that date, and late payment penalties may apply if you pay after June 16.
Need more time beyond June 16, 2025?
Many US expats find that the automatic two-month extension to June 16 isn’t enough. Gathering all necessary documents from foreign banks, employers, or local tax authorities can take longer than expected. If you need more time, don’t worry – you can request an additional extension to October 15, 2025. By securing this extra time, you avoid late filing penalties while staying fully compliant with IRS deadlines.
Request your expat tax extension in just a few clicks at Taxes for Expats and push your tax filing deadline From June 16, 2025 to October 15, 2025 – it’s completely free of charge.
