April 15th, June 15th, and October 15th
*If the 15th falls on a weekend, then the due date becomes the first business day of the following week. In 2023 that makes the deadline April 18th.
Expatriates must be aware of the following deadlines for their US expat tax return.
April 18th:
US filing deadline and the date that tax payments are due, even for expats.
June 15th:
US expats receive an automatic extension until June 15th to file their US taxes; note that taxes are due on April 18th, and interest (but no penalties) will be applied if taxes are not paid by April 18th. Penalties will apply if taxes are not paid by June 15th. The 15th is also the FBAR deadline for US expats; however, there is an automatic extension until the October 15th deadline.
October 15th:
Final deadline for expat tax returns for those who have filed for an extension. This is also the final deadline for filing an FBAR.
Please Note: The US Federal tax return extension is an extension of time to file and not an extension of time to pay any tax due to the IRS. If you owe tax to the US, your interest will start accruing from the first tax deadline – April 18th. Additionally, if you do not request an extension and do not file, a late payment penalty of 5% may be assessed each month until the tax is paid.
Learn more about deadlines and extensions in our knowledge center guide.
If you are a resident alien, generally you will have the same filing requirements as a US citizen within the US.
If you are living in the US, you will have the same filing deadline as other residents and citizens: April 18th.
However, if your main place of residence is still outside the US, you will have an automatic extension until June 15th (please note that all taxes owed will still be due by April 18th) for your tax return filing.
