At Taxes for Expats we work hard to make your US Tax filing process as easy and hassle-free as possible. That means processing all your tax documents online and e-filing your return.

Please make sure to use the correct mailing address and submit your paper return to the IRS Service Center that handles returns of your type. If you file in response to an IRS notice, check with the agent handling your case before mailing your tax return.
