Apply for Your ITIN with an IRS-Authorized Certifying Acceptance Agent

An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the U.S. Internal Revenue Service (IRS) to individuals who are required to have a U.S. taxpayer identification number but are not eligible for a Social Security Number (SSN). It is used only for federal tax purposes.

You typically need an ITIN if you must file or be listed on a U.S. federal tax return and you are not eligible for an SSN. This may include nonresident aliens required to file a U.S. tax return, resident aliens (under the substantial presence test) who cannot get an SSN, dependents or spouses of U.S. citizens or resident aliens, and dependents or spouses of nonresident aliens on certain visas.

To apply for an ITIN, you must complete Form W-7 (Application for IRS Individual Taxpayer Identification Number), attach the required identification documents (such as a valid passport or other accepted documents), and usually include a U.S. federal tax return or proof that you qualify for an exception. With TaxGov, we proceed the ITIN with a Certifying Acceptance Agent (CAA).
