Your Individual Taxpayer Identification Number (ITIN) does not expire. However, the IRS can invalidate your ITIN if you do not file a U.S. federal tax return using it for three consecutive tax years. If your ITIN becomes invalid, you will need to reapply for a new one if you need to file a U.S. tax return or are otherwise required to have an ITIN.
ITIN Invalidation and Renewal
The IRS generally invalidates ITINs that have not been used on a federal tax return for three consecutive tax years. This means if you have an ITIN but haven't filed a tax return with it for, say, 2021, 2022, and 2023, your ITIN might be considered invalid for the 2024 tax year. The IRS will notify you if they intend to invalidate your ITIN, typically through a notice sent to your last known address. The specific notice you might receive is Notice CP-48, which informs you that your ITIN is subject to expiration.
If your ITIN is invalidated, you must reapply for a new one using Form W-7, Application for IRS Individual Taxpayer Identification Number. The reapplication process is the same as the initial application. You will need to provide original identification documents or certified copies from the issuing agency, along with a U.S. federal tax return to which the ITIN is necessary. You cannot simply reactivate an old ITIN; you must go through the full application process again. Understanding whether your ITIN is still valid is crucial, especially if you are planning to file taxes after a period of absence from U.S. tax obligations.
Who Needs an ITIN and Why it Matters
An ITIN is issued by the 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). This includes many non-resident aliens who need to file U.S. tax returns, such as those earning U.S. source income, claiming tax treaty benefits, or meeting other tax filing requirements. Foreign nationals who are not U.S. residents but have U.S. tax obligations, like those owning a U.S. business or rental property, are common recipients of ITINs.
An ITIN is essential for various tax-related activities. For instance, if you are a non-resident alien who owns a U.S. LLC and you need to file Form 5472, Information Return of a 29% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a Trade or Business in the United States, you will need an ITIN. This form is generally due by April 15th each year for the preceding tax year, though extensions are possible. Failure to file Form 5472 can result in significant penalties. Similarly, if you are an alien individual with U.S. income that is subject to U.S. tax withholding, you will need an ITIN to file your tax return, such as Form 1040-NR, U.S. Nonresident Alien Income Tax Return. Without a valid ITIN, you may face challenges in accurately reporting income, claiming deductions or credits, and complying with U.S. tax laws.
Furthermore, an ITIN can be instrumental in opening a U.S. bank account for non-residents. While not all U.S. banks or financial institutions accept ITINs for account opening, many do, especially those catering to international clients. Having a U.S. bank account can simplify financial transactions related to U.S. investments, businesses, or personal finances. Services like Mercury, Relay, or Brex often require a U.S. business presence and associated tax identification numbers, which could include an ITIN if an SSN is unavailable.
How to Determine if Your ITIN is Still Valid
To determine if your ITIN is still valid, the most straightforward method is to check if you have used it on a federal tax return within the last three consecutive tax years. If you have, it is likely still valid. If you have not filed a tax return for three or more consecutive years, your ITIN may have been invalidated by the IRS.
If you are unsure about the status of your ITIN, you can contact the IRS directly. You can call the IRS ITIN line at 800-829-1040. They can look up your ITIN and inform you if it has been invalidated. Alternatively, if you have received a notice from the IRS about your ITIN, such as Notice CP-48, it will provide specific instructions and information regarding its status. It's important to act promptly if you receive such a notice, as there are deadlines for responding or reapplying.
Another way to confirm is by checking your prior tax filings. If you have copies of tax returns where your ITIN was used, this serves as proof of its active use. However, even if you have used it in the past, the three-year rule still applies. If your last filing was more than three years ago, and you have not filed since, your ITIN might be invalid. The question of "does itin number expire?" is best answered by understanding this three-year inactivity rule.
Reapplying for an ITIN
If your ITIN has been invalidated due to inactivity, or if you never received one and now need it, you must reapply using Form W-7, Application for IRS Individual Taxpayer Identification Number. The process for reapplying is largely the same as the initial application. You will need to complete Form W-7 accurately and submit it with the required supporting documentation.
The primary supporting document is your U.S. federal tax return for the year you need the ITIN for. This could be your Form 1040-NR or another applicable tax form. Without an attached tax return, the IRS will generally not issue an ITIN, unless you qualify for an exception (e.g., certain treaty benefits or specific withholding situations). You must also provide original identification documents or certified copies from the issuing agency. Acceptable documents include passports, national identity cards, driver's licenses, and birth certificates. The IRS will verify these documents and return them to you.
There are three main ways to submit your Form W-7 application:
- Mail directly to the IRS: You can mail your completed Form W-7, along with your tax return and original or certified identification documents, to the IRS address specified in the Form W-7 instructions. This is the most common method but can have the longest processing times.
- Through a Certified Acceptance Agent (CAA): This is often the preferred method for many applicants. A CAA is an individual or entity authorized by the IRS to help taxpayers apply for ITINs. CAAs can verify your original identification documents and forward your application to the IRS. Using a CAA can expedite the process as they handle the primary verification, and you typically get your original documents back sooner. itin.net is a service that can guide you through the process of finding and working with a CAA.
- Through an IRS Taxpayer Assistance Center (TAC): Some IRS Taxpayer Assistance Centers offer ITIN application processing. You must make an appointment, and they will review your documentation. However, not all TACs provide this service, so it's essential to check beforehand.
Each method has its own processing times, which can vary significantly. The IRS processes ITIN applications on a first-come, first-served basis. Processing can take anywhere from 7 to 11 weeks, depending on the volume of applications the IRS is handling and the method you choose.
Documents Required for Reapplication
The documentation requirements for reapplying for an ITIN are identical to those for an initial application. You must submit Form W-7, completed accurately. You also need to submit a valid federal income tax return for the tax year for which you require the ITIN, unless you qualify for an exception to the return-filing requirement.
Crucially, you must provide original identification documents or certified copies from the issuing agency. The IRS has a list of acceptable documents on the Form W-7 instructions. The most commonly used and recommended document is a valid passport, as it serves as both proof of identity and nationality. If you don't have a passport, other documents can be used, such as a national identity card, a U.S. driver's license, a foreign driver's license, a U.S. state-issued ID card, or a U.S. visa. A combination of documents may be required if a single document does not provide both identity and nationality.
If you are applying for an ITIN for a dependent, you will need to provide the dependent's identification documents as well as proof of your relationship to the dependent (e.g., a birth certificate). For spouses, a marriage certificate may be required. Remember, the IRS prefers original documents. If you cannot mail your original documents, you can have them certified by the issuing agency or use a Certified Acceptance Agent (CAA), like those associated with itin.net, who can certify them for you.
Processing Times and Potential Delays
Processing times for Form W-7 applications can vary. Currently, the IRS estimates that it can take between 7 to 11 weeks to process an ITIN application once it is received and accepted for processing. This timeframe can be longer during peak tax filing seasons (January through April) or if there are a high volume of applications. If you apply through a CAA, the initial verification by the agent is usually quick, but the subsequent IRS processing time remains the same. Applying via mail directly to the IRS can sometimes lead to longer overall wait times.
Delays can occur for several reasons. Incomplete applications are a common cause of delays; ensure all sections of Form W-7 are filled out correctly and that all required supporting documents are included. If you are mailing original documents, the time it takes for the IRS to return them can also add to the overall timeline. If your application is selected for review, it might take longer than the standard processing window. It is advisable to apply for your ITIN well in advance of any tax deadlines to avoid complications. If you are planning to establish a U.S. LLC and need an ITIN to facilitate that, or if you are looking to open a U.S. bank account, factor in these processing times.
What to Do if You Receive a Notice from the IRS
If you receive a notice from the IRS regarding your ITIN, such as Notice CP-48, it is crucial to read it carefully and understand its contents. This notice typically informs you that your ITIN is subject to expiration due to inactivity (i.e., not being used on a federal tax return for three consecutive years). The notice will specify the ITIN in question and may provide a deadline for responding or taking action.
If the notice states your ITIN is invalid or subject to expiration, and you still need it for tax filing purposes, you must reapply. The notice itself often serves as a trigger for you to begin the reapplication process using Form W-7. Gather your required identification documents and your most recent U.S. federal tax return. You can then submit your application directly to the IRS or through a Certified Acceptance Agent (CAA).
Do not ignore IRS notices. Failure to respond or reapply when necessary can lead to issues with future tax filings, potential penalties, and difficulties in conducting U.S. financial or business activities that require a valid ITIN. If you are unsure about the notice or the reapplication process, seeking assistance from a qualified tax professional or a CAA is highly recommended. They can help you interpret the notice and ensure your reapplication is submitted correctly.
ITIN vs. SSN: Key Differences
It is important to distinguish an ITIN from a Social Security number (SSN). An SSN is issued by the Social Security Administration (SSA) to U.S. citizens, permanent residents, and eligible temporary (working) residents. An SSN allows individuals to work legally in the United States and is used for various financial and employment purposes. If you are eligible for an SSN, you must obtain one instead of an ITIN.
An ITIN, on the other hand, is issued by the IRS solely for tax administration purposes. It does not authorize you to work in the U.S. and does not confer eligibility for Social Security benefits. The primary function of an ITIN is to enable individuals who are not eligible for an SSN to comply with U.S. tax laws. While both are taxpayer identification numbers, their purpose, issuing authority, and eligibility criteria are distinct. For example, if you are a foreign national looking to start a business and need an EIN (Employer Identification Number), which is obtained via Form SS-4, you might first need an ITIN if you don't have an SSN to apply for the EIN directly. The EIN itself does not expire and is used for business tax purposes.
Planning for Future Tax Obligations
Even if your ITIN is currently valid, it's wise to plan for future tax obligations and maintain its validity. If you anticipate not filing a U.S. tax return for a year or two, be aware of the three-year rule. If you foresee a period of inactivity, consider filing a minimal return, such as a return reporting zero income or a return claiming treaty benefits, to keep your ITIN active. This proactive approach can save you the hassle of reapplying later.
For individuals who are establishing a presence in the U.S. through a U.S. LLC or other business structures, it's essential to understand the ongoing tax compliance requirements. This includes filing annual tax returns (like Form 5472 for LLCs with foreign owners) and ensuring all tax obligations are met. For those who may eventually become eligible for an SSN, the transition from an ITIN to an SSN should be managed carefully to avoid any disruptions in tax reporting or financial activities.
Remember that an ITIN is a tax processing number. If your circumstances change and you become eligible for an SSN, you should apply for one with the SSA. Once you have an SSN, you should use it for all tax filings going forward, and you will no longer need your ITIN. The IRS will automatically update your record to reflect your SSN. Planning ahead and staying informed about U.S. tax regulations will help you maintain compliance and avoid unexpected issues related to your taxpayer identification number.
