How and where to file

When filing your tax return from outside of the 50 US states (unless you have an APO or FPO address), you should mail it to this address:

Department of the Treasury
Internal Revenue Service Center
Austin, TX 73301-0215
USA

If you have an APO or FPO address and you are enclosing a check for tax payment, then you should use this address:

Department of the Treasury
Internal Revenue Service Center
Austin, TX 73301-0102
USA

If you have an APO or FPO address and you are not enclosing a check for tax payment, then you should use this address:

Department of the Treasury
Internal Revenue Service Center
Austin, TX 73301-0002
USA

Courier services such as FedEx and UPS will deliver to these addresses. If you live in a country where mail is unreliable or slow, it's advisable to spend the extra few dollars to use one of these services.

We do not recommend using your post office's Registered Mail service, because it can cause delivery delays.
