An ITIN does not expire and remains valid for life unless revoked or cancelled by the IRS. The primary reason an ITIN might become invalid is if you do not file a U.S. federal income tax return for three consecutive tax years. In such cases, the IRS may choose to revoke or cancel your ITIN. Therefore, to maintain the validity of your ITIN, it is essential to file a U.S. tax return at least once every three years.
Understanding ITIN Validity
The Internal Revenue Service (IRS) issues Individual Taxpayer Identification Numbers (ITINs) 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). This includes resident and non-resident aliens, their spouses, and dependents who cannot get an SSN. The ITIN itself is a nine-digit number structured like an SSN but always beginning with the number 9, followed by a hyphen, the fourth digit (0), and then the remaining six digits. For example, 9XX-7X-XXXX. The ITIN is assigned solely for federal tax reporting purposes. It does not authorize employment in the U.S., provide eligibility for Social Security benefits, or grant any other privileges associated with an SSN.
An ITIN's validity is not tied to a specific expiration date printed on a card or document. Instead, the IRS uses filing activity as the primary indicator of continued need. If an individual has an ITIN and is not required to file a U.S. tax return for a given year, they are not obligated to file. However, if they are required to file and fail to do so for three consecutive years, the IRS may consider the ITIN inactive. This policy is in place to ensure that ITINs are actively used by individuals who have a U.S. tax obligation.
When an ITIN Becomes Invalid
The most common scenario where an ITIN ceases to be valid is the aforementioned three-year period of non-filing. If you have an ITIN and do not file a U.S. federal income tax return for three consecutive tax years (e.g., 2021, 2022, and 2023), the IRS may revoke your ITIN. This revocation typically occurs after the third year has passed and the IRS has processed returns for that year. You would not receive a specific notification that your ITIN has been revoked unless you attempt to use it on a subsequent tax filing or for another IRS-related process.
It is important to distinguish between an ITIN becoming invalid due to non-filing and the need to renew specific digits of the ITIN. In 2019, the IRS announced a phased renewal program for ITINs that had not been used on a federal tax return within the last three years and whose middle digits fell within certain ranges. This renewal was a proactive measure by the IRS to update its records. If your ITIN was subject to this renewal and you did not renew it, it may have become invalid. However, the core principle of needing to file a tax return to maintain validity remains the primary driver.
The Three-Year Rule Explained
The IRS generally considers an ITIN inactive if it has not been used on a federal tax return for three consecutive tax years. For example, if you last filed a tax return using your ITIN for the 2020 tax year, and you do not file for the 2021, 2022, or 2023 tax years, your ITIN may be considered invalid starting in 2024. The IRS makes these determinations based on its internal records of tax filings. This rule ensures that ITINs are primarily held by individuals who are actively engaged in U.S. tax matters or have a U.S. tax obligation.
If your ITIN has become invalid due to this three-year rule, you will need to apply for a new one if you are required to file a U.S. tax return or need an ITIN for another valid tax purpose. The application process for a new ITIN is identical to the process for obtaining an original ITIN. This involves completing Form W-7, Application for IRS Individual Taxpayer Identification Number, and providing original or certified copies of identification documents. The application can be submitted directly to the IRS or through a Certified Acceptance Agent (CAA). Using a CAA can streamline the process, as they can verify your original identification documents and transmit them with your Form W-7 to the IRS on your behalf, often returning your original documents the same day. itin.net is a service that can assist with this process, connecting you with resources and guidance for your ITIN application.
How to Maintain Your ITIN's Validity
To ensure your ITIN remains valid, the simplest and most direct method is to file a U.S. federal income tax return at least once every three years. Even if you owe no tax or are due a refund, filing a return signals to the IRS that you still require the ITIN. If you have an ITIN and are not required to file a tax return in a given year (for instance, if your income is below the filing threshold and you have no other filing requirements), you generally do not need to take any action to maintain your ITIN's validity for that year. The IRS's focus is on the absence of filing activity over a three-year span.
If you are an individual who is required to file U.S. tax returns but no longer live in the U.S., you will likely continue to file Form 1040-NR, U.S. Nonresident Alien Income Tax Return, or other applicable tax forms. If you have an ITIN and are involved in U.S. business activities, such as owning a U.S. LLC, you may have filing obligations even if you are not a U.S. resident. For example, if you are the sole member of a U.S. LLC and it is a disregarded entity, you may need to file Form 5472 and Form 1040-NR to report certain transactions. Failure to file these forms can lead to penalties and may impact the validity of your ITIN if it falls within the three-year non-filing period.
