You can and should use your foreign address when filing your U.S. tax return. Enter this information in the "Mailing Address and Phone Number" section of "Personal Info".
Hint: You have to check the "Other" box the enter a foreign address, and you have to enter a U.S. phone number.
The IRS asks for
your phone number and mailing address in case they have a question about your return (this is
rare). They will not, however, call an international phone number.
In order to complete and e-file your return,
you can enter the phone number of a relative or friend in the U.S,, or a
"dummy number" (800-555-1212). The
IRS will identify your entry as a placeholder number - if they have
questions, they will mail them to you at the foreign address.
