Your Individual Taxpayer Identification Number (ITIN) generally does not expire. The IRS only invalidates an ITIN if it has not been used on a federal tax return for three consecutive tax years. If your ITIN has been used regularly, it remains valid indefinitely. The primary way to know if your ITIN is still active is by checking if it has been used on a tax return within the last three years. If you have filed a U.S. federal income tax return using your ITIN in the past three tax years (e.g., 2023, 2022, 2021), your ITIN is considered valid.
Understanding ITIN Validity
The IRS issues ITINs to individuals who need a U.S. taxpayer identification number but do not have, and are not eligible to obtain, a Social Security Number (SSN). These individuals include certain non-resident aliens, resident aliens, and others who have U.S. tax reporting requirements. The purpose of an ITIN is solely for tax processing. It does not grant work authorization or provide eligibility for Social Security benefits. The IRS does not send out renewal notices for ITINs that are nearing expiration due to inactivity. Instead, it's up to the taxpayer to ensure their ITIN is valid when they need to file a tax return. If your ITIN has been inactive for three consecutive tax years, the IRS may choose to decommission it. This means you would need to apply for a new ITIN.
How to Determine if Your ITIN is Active
The most direct method to check how to check itin expiration date is to review your past tax filings. If you have filed a federal tax return using your ITIN for the tax year 2021, 2022, or 2023, your ITIN is active.
Checking Past Tax Returns
When you file a federal tax return, you must enter your ITIN on the appropriate lines of the tax form, typically Form 1040-NR (U.S. Nonresident Alien Income Tax Return) or Form 1040 (U.S. Individual Income Tax Return) if you are a dual-status alien or resident alien for tax purposes. Keep copies of all federal tax returns you have filed. Your copy of the tax return will clearly show your ITIN and the tax year for which it was used. If you have a filed return from 2021, 2022, or 2023, your ITIN is active.
What if You Don't Have Copies of Past Returns?
If you no longer have copies of your past tax returns, you can request a transcript of your tax account from the IRS. A transcript is a summary of your account, including information about your filed tax returns. You can request an IRS tax transcript by:
- Online: Using the IRS's Get Transcript Online tool. You will need to verify your identity, which may be challenging if you have never filed a tax return or do not have a U.S. address and phone number. This tool is primarily designed for U.S. residents.
- By Mail: Completing and mailing Form 4506-1, Request for a Transcript of Tax Return. This form can be mailed to the IRS, and the transcript will be sent to the address on file with the IRS. Processing can take several weeks.
- By Phone: Calling the IRS toll-free at 800-908-9946. You will need to verify your identity.
Your tax transcript will list the tax years for which returns were filed. If a return using your ITIN appears for 2021, 2022, or 2023, your ITIN is active.
What Happens if Your ITIN Has Expired or Been Decommissioned?
If your ITIN has not been used for three consecutive tax years, the IRS may decommission it. This means you will need to apply for a new ITIN. The process for applying for a new ITIN is the same as applying for your original ITIN. You will need to complete Form W-7, Application for IRS Individual Taxpayer Identification Number. You will also need to provide original documentation or certified copies of your identification and foreign status. This includes your passport, which is the most commonly used document.
Applying for a New ITIN
The application process involves submitting Form W-7 along with original or certified copies of your identification documents and proof of foreign status. You can submit your application:
- By Mail: Send your completed Form W-7, supporting documents, and a valid U.S. federal income tax return to the IRS address specified in the Form W-7 instructions. Your application will not be processed without an accompanying tax return unless you qualify for an exception (e.g., applying for an ITIN solely to claim tax treaty benefits).
- Through a Certified Acceptance Agent (CAA): You can apply through a CAA. These agents are authorized by the IRS to help you complete and submit your Form W-7 application. They can also verify your original identification documents, which means you don't have to mail your original passport or other sensitive documents to the IRS. itin.net works with a network of CAAs to assist individuals in this process.
- At an IRS Taxpayer Assistance Center (TAC): Some IRS TACs offer ITIN application services by appointment. You must call to schedule an appointment and bring your original documentation.
The IRS generally processes Form W-7 applications within 7 to 11 weeks. The timeline can vary depending on the volume of applications received by the IRS.
Reasons for ITIN Invalidation (Beyond Non-Use)
While non-use is the primary reason an ITIN can be invalidated, there are other less common scenarios. For instance, if an ITIN was issued in error or obtained through fraudulent means, the IRS has the authority to revoke or invalidate it. However, for most individuals who obtained an ITIN legitimately and have used it for tax purposes, the concern is typically only about the three-year rule of inactivity.
ITIN Renewal and Reapplication
It is important to clarify that ITINs do not have a fixed expiration date that requires proactive renewal in the same way a driver's license or passport does. The only condition that leads to an ITIN becoming inactive is the lack of use on a federal tax return for three consecutive years. If your ITIN has been invalidated due to non-use, you must reapply for a new ITIN by submitting Form W-7 and the required documentation, as outlined previously. This reapplication process is identical to the initial application.
When You Might Need a New ITIN
Beyond the three-year rule, you might need to apply for a new ITIN if:
- You have never been issued an ITIN before, but now have a U.S. tax filing requirement.
- You were issued an ITIN, but it was invalidated due to non-use, and you now need to file a U.S. tax return.
- You have legally changed your name and did not notify the IRS. You would need to apply for a new ITIN using your new name, providing documentation of the name change.
- You were issued an SSN after receiving an ITIN. You must stop using your ITIN and use your SSN for all tax purposes. You do not need to apply for a new ITIN in this case; your SSN replaces it.
Next Steps After Confirming Your ITIN is Active
If you have confirmed that your ITIN is active, you can proceed with filing your U.S. federal tax return. Ensure you are using the correct tax form for your residency and income situation. Non-resident aliens typically use Form 1040-NR. If you are establishing a U.S. business presence, such as forming a U.S. LLC, you may also need an EIN (Employer Identification Number) from the IRS. An EIN is different from an ITIN and is used for business tax identification. Opening a U.S. bank account as a non-resident often requires both an ITIN and potentially an EIN, depending on the business structure.
Seeking Assistance with ITIN Matters
If you are unsure about your ITIN's status or need help applying for a new one, consider using the services of a Certified Acceptance Agent. These agents are trained to assist with the ITIN application process and can help ensure your application is complete and accurate, reducing the risk of delays or rejection. For complex situations or personalized advice, consulting a qualified tax professional or an attorney specializing in U.S. tax law for non-residents is recommended.
