8.1- Resident and Non Resident Aliens
If you are a U.S. citizen or resident alien, the rules for filing income, estate, and gift tax returns and paying estimated tax are generally the same whether you are in the United States or abroad. You are subject to tax on worldwide income from all sources and must report all taxable income and pay taxes according to the Internal Revenue Code.
Many Americans living abroad qualify for special tax benefits, such as the foreign earned income exclusion and foreign tax credit, but they can only get them by filing a U.S. return. For further details, see Publication 54, Tax Guide for U.S. Citizens and Resident Aliens Abroad.
U.S. taxpayers who own foreign financial accounts must report those accounts to the U.S. Treasury Department, even if the accounts don't generate any taxable income. Taxpayers should file a Report of Foreign Bank and Financial Accounts (FBAR) electronically by April 18, 2022, using the BSA E-Filing System. For further details see Report of Foreign Bank and Financial Accounts (FBAR).
Taxpayers must also report virtual currency transactions to the IRS on their tax returns; these transactions are taxable by law just like any other property transaction. For more information see Virtual Currencies.
When to File
If you are a U.S. citizen or resident alien residing overseas, or are in the military on duty outside the U.S., on the regular due date of your return, you are allowed an automatic 2-month extension to file your return without requesting an extension. For a calendar year return, the automatic 2-month extension is to June 15. For calendar year 2021 you must pay any tax due by April 18, 2022, or interest will be charged.
If you qualify for the 2-month extension but are unable to file your return by the automatic 2-month extension date, you can request an additional extension to October 15 by filing Form 4868, Application for Automatic Extension of Time To File U.S. Individual Income Tax Return, before the automatic 2-month extension date. If you are allowed extensions to June 15 and/or October 15, you will owe interest on any unpaid tax amount from the original due date of the return (April 18, 2022, for calendar year 2021).
