Internal Revenue Service Information
The Internal Revenue Service (IRS) can assist you with U.S. federal income taxes and provide you with the required forms. U.S. citizens that live abroad generally need to follow the same rules as those in the United States.
You will find useful information on the Internal Revenue Service (IRS) website, such as Frequently Asked Questions about taxes, how to apply for an Individual Taxpayer Identification Number (ITIN), or Foreign Account Tax Compliance Act (FATCA): https://www.irs.gov/individuals/international-taxpayers/us-citizens-and-resident-aliens-abroad
