An IRS Tax Return (Certified Copy) is an official document issued directly by the Internal Revenue Service (IRS). It serves as a government-verified copy of your tax return and is often required for international matters such as immigration, residency, foreign bank account verification, real estate transactions abroad, academic applications, or employment background checks.

When presenting a certified IRS tax return in another country, many foreign authorities require the document to be apostilled or legalized, depending on whether the receiving country is part of the Hague Apostille Convention. Because the IRS is a federal agency, this document must be apostilled at the federal level through the U.S. Department of State.
