Your Individual Taxpayer Identification Number (ITIN) does not expire. However, an ITIN can become invalid for tax filing purposes if you do not report it on a U.S. federal income tax return for three consecutive tax years. The IRS also has the authority to issue new ITINs to existing ITIN holders. For these reasons, it is important to understand how to determine if your ITIN is still valid for its intended use, particularly if you are asking how to check if itin is expired online.
Understanding ITIN Validity
An ITIN is a nine-digit number issued by the Internal Revenue Service (IRS) to individuals who are required to have a U.S. taxpayer identification number but do not have, and are not eligible to obtain, a Social Security number (SSN). These individuals include non-resident aliens who need to file U.S. tax returns, dependents, and spouses of U.S. citizens or resident aliens, among others. The ITIN is primarily used for federal tax purposes. It is not a form of identification for general purposes and does not grant work authorization or legal immigration status.
The primary way an ITIN becomes inactive is through non-use. If you do not file a federal tax return using your ITIN for three consecutive tax years, the IRS will consider it inactive. For example, if you did not file a tax return for the 2021, 2022, and 2023 tax years, your ITIN would become inactive at the beginning of the 2024 tax year. This inactivity rule applies regardless of whether you received the ITIN for yourself, a dependent, or a spouse. The IRS implements this rule to ensure that ITINs are actively used for their intended tax administration purposes.
Furthermore, the IRS may issue new ITINs to individuals who already have one. This can happen if the IRS updates its ITIN assignment process or if there are changes in tax law that necessitate re-assignment. While the number itself may change, the underlying need for a taxpayer identification number usually remains. The IRS typically notifies individuals if a new ITIN has been assigned to them. If you receive a notice from the IRS about a new ITIN, it is important to use the new number for all future tax filings and to discontinue the use of the old one.
