An ITIN, or Individual Taxpayer Identification Number, is a nine-digit number issued by the U.S. Internal Revenue Service (IRS). It follows the format 9XX-XX-XXXX. The number itself does not expire and remains valid indefinitely for identification purposes unless it is revoked or has never been used on a federal tax return for three consecutive filing years. When the IRS issues an ITIN, it is for life, unless revoked or invalidated by the IRS.
What is an ITIN and Who Needs One?
An ITIN is for federal tax purposes only. It is assigned to individuals who are required to have a U.S. taxpayer identification number but who 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, individuals who are U.S. resident aliens and are filing a U.S. federal tax return but are not eligible for an SSN, and dependents or other individuals claimed on a U.S. federal tax return.
Examples of individuals who may need an ITIN include:
- Non-resident aliens who need to file a U.S. tax return (e.g., to claim treaty benefits or report U.S. source income).
- U.S. resident aliens (based on days present in the U.S.) who are filing a U.S. tax return but are not eligible for an SSN.
- Dependents or spouses of U.S. citizens or resident aliens who are not eligible for an SSN.
- Individuals who are eligible to work in the U.S. but have not been issued an SSN (though they should apply for an SSN in this case).
- Individuals who need to open a U.S. bank account and are not eligible for an SSN. Many U.S. banks require a taxpayer identification number for account opening, and an ITIN can often fulfill this requirement. This is a common reason individuals seek an ITIN, and itin.net can assist with this process. Opening a U.S. bank account is often a necessary step for those planning to establish a business in the U.S.
It is important to distinguish an ITIN from an Employer Identification Number (EIN), also known as an Form SS-4. An EIN is used to identify a business entity, not an individual. If you are forming a business, such as a U.S. LLC, you will likely need an EIN in addition to any ITINs required for individuals associated with the business. itin.net also provides services for obtaining an EIN.
Does an ITIN Expire?
No, an ITIN itself does not expire. Once issued, an ITIN is valid for the lifetime of the individual unless it is revoked by the IRS or invalidated due to non-use. The IRS established the ITIN program in 1996 to ensure that all taxpayers who are required to file U.S. taxes could do so, even if they were not eligible for an SSN. The number is a permanent identifier for tax purposes.
However, there is a critical nuance regarding ITIN validity and usage. The IRS has a policy that if an ITIN is not used on a federal tax return for three consecutive filing years, the IRS may choose to suspend or invalidate it. This means that while the number assigned to you theoretically remains yours, it may cease to be recognized by the IRS for tax processing if it has been inactive for an extended period. This is a key consideration for anyone asking "how long is an itin number" valid for practical purposes.
When Does the IRS Suspend or Invalidate an ITIN?
The IRS may suspend or invalidate an ITIN if it has not been used on a federal tax return for three consecutive tax years. This policy is in place to ensure that ITINs are actively used for their intended purpose: filing U.S. taxes. If your ITIN has been suspended, you will need to go through the application process again by submitting Form W-7, Application for IRS Individual Taxpayer Identification Number, along with the required supporting documentation, to have it reactivated.
This reactivation process is essentially the same as applying for a new ITIN. You will need to provide proof of identity and foreign status, and the IRS will assign you a new ITIN. While the IRS states that previously issued ITINs will not be reissued, they will assign a new number if your old one has been suspended due to inactivity. The process can take several weeks, similar to an initial application.
ITIN Renewal Requirements
While ITINs do not expire, the IRS has implemented a renewal program for certain ITINs. This program is not about the ITIN number itself expiring, but rather about ensuring that the IRS has up-to-date information and that ITINs are still being used for tax purposes. As of recent IRS policies, ITINs that have not been used on a federal tax return for three consecutive years may be inactivated.
Furthermore, the IRS has identified specific groups of ITINs that are subject to renewal based on their issuance date. For example, ITINs issued in the early years of the program may be subject to renewal. The IRS typically announces these renewal requirements through specific notices and updates on its website. If your ITIN falls into one of these categories, you will need to renew it by submitting a new Form W-7 application.
Who Needs to Renew Their ITIN?
Not all ITIN holders need to actively renew their ITIN. The IRS renewal initiative typically targets ITINs that have not been used for tax filing for three consecutive years or those issued during specific periods. The IRS communicates directly with affected individuals through mailings, often sending notices like CP-565 (Notice of ITIN Assignment) or other correspondence informing them of the need to renew.
If you have an ITIN and have used it regularly on your tax filings, you generally do not need to worry about renewal unless you receive a specific notice from the IRS. If you have an ITIN but have not filed a U.S. tax return in the last three years, your ITIN may have been inactivated, and you will need to reapply. This reapplication process is identical to applying for a new ITIN.
How to Renew an ITIN
To renew an ITIN, you must complete and submit Form W-7, Application for IRS Individual Taxpayer Identification Number, along with the required original or certified copies of documentation proving your identity and foreign status. The documentation requirements are the same as for a new ITIN application. You will need to provide documents such as a valid passport, national identification card, or birth certificate. The IRS strongly recommends using a Certified Acceptance Agent (CAA) to help with the application process. CAAs are individuals or entities authorized by the IRS to assist taxpayers in applying for ITINs. They can verify your original documentation, which means you do not have to mail your original documents to the IRS. itin.net works with a network of CAAs to help individuals secure their ITINs efficiently.
Alternatively, you can submit your application by mail to the IRS ITIN Operation in Austin, Texas, or by making an appointment at certain IRS Taxpayer Assistance Centers (TACs). Submitting original documents by mail carries a risk of loss or damage, making the CAA route often preferable for many applicants. The processing times for renewals are similar to those for new applications, which can range from several weeks to a few months, depending on the volume of applications the IRS is processing.
Processing Times for New ITINs and Renewals
The processing time for a new ITIN application or a renewal can vary significantly. Historically, processing could take anywhere from 4 to 10 weeks. However, during periods of high application volume, or due to IRS staffing and operational changes, these times can extend. The IRS aims to process applications as quickly as possible, but it is wise to apply well in advance of any tax deadlines.
If you are applying through a Certified Acceptance Agent (CAA), the initial verification of your documents is immediate. However, the IRS still needs to process the application and assign or reactivate the ITIN, which can take several weeks. If you are mailing your application directly to the IRS, you must also factor in the time for your documents to be mailed to and from the IRS processing center, in addition to the IRS processing time itself. This can add several more weeks to the overall timeline.
It is crucial to submit all required documentation correctly. Incomplete applications are a primary reason for delays. The IRS will send you a notice if there is an issue with your application, but this further extends the processing time. The IRS issues a CP-565 notice once your ITIN has been assigned. If your ITIN has been suspended due to non-use, and you reapply, the IRS will assign you a new ITIN and send a similar notice.
How to Keep Your ITIN Active
The most straightforward way to keep your ITIN active and prevent it from being suspended due to inactivity is to file a federal tax return using it at least once every three years. Even if you do not owe any taxes or are not required to file, filing a return (such as Form 1040-NR for non-resident aliens) will ensure your ITIN remains in use. This is the IRS's primary mechanism for determining if an ITIN is still needed by the holder.
If you have an ITIN and are not currently required to file a U.S. tax return, but anticipate needing one in the future (e.g., for business purposes, investing, or banking), you should be aware of the three-year inactivity rule. If your ITIN has been invalidated due to non-use, you will need to reapply for a new one using Form W-7. This means going through the entire documentation verification process again. The IRS does not reactivate suspended ITINs; they are effectively replaced with a new one upon successful reapplication.
What Happens If My ITIN is Suspended or Invalidated?
If your ITIN has been suspended or invalidated due to non-use, it means the IRS no longer recognizes it for tax processing purposes. You cannot use a suspended ITIN to file tax returns or for any other official IRS matters. You will need to apply for a new ITIN if you require one.
The process to obtain a new ITIN after suspension is identical to applying for an ITIN for the first time. You must complete Form W-7, provide original or certified copies of your identification documents (proof of identity and foreign status), and submit the application to the IRS. This can be done by mail or through an authorized Certified Acceptance Agent (CAA). Using a CAA like those associated with itin.net is often recommended because they can verify your documents in person, avoiding the need to mail originals.
Once the IRS processes your new Form W-7 application, they will assign you a new ITIN. You will receive a CP-565 notice from the IRS confirming the assignment of your new ITIN. This new ITIN will then be valid for your future tax filing and other U.S. tax-related requirements. It is important to update any financial institutions or other entities where you have previously provided your old ITIN with your new one.
ITINs and U.S. Business Requirements
For many foreign nationals, obtaining an ITIN is a stepping stone to engaging in U.S. business activities. While an ITIN is for individuals, business entities often require their own identifier, the Employer Identification Number (EIN). If you are forming a U.S. LLC, you will typically need to obtain an EIN for the LLC. An ITIN may be required for the foreign owner of the LLC if they are to receive distributions or have other U.S. tax reporting obligations. The process for forming a U.S. LLC and obtaining an EIN can be complex, and itin.net can assist with these services as well, providing a comprehensive solution for individuals looking to establish a U.S. presence.
Furthermore, opening a U.S. bank account is often a critical requirement for operating a U.S. business. Many banks require a taxpayer identification number for account holders. While an SSN is preferred, an ITIN can often be used by foreign individuals to open business or personal bank accounts. This facilitates transactions, payroll, and other financial operations. Services for opening U.S. bank accounts are also available, helping to streamline the process for international entrepreneurs.
If you are operating a U.S. LLC as a foreign owner, you will likely encounter Form 5472, Information Return of a 24% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business. This form is used to report transactions between the U.S. entity and its foreign owner. Failure to file Form 5472 can result in significant penalties. Having an ITIN or an EIN is often necessary to file this form correctly.
Seeking Assistance with ITIN Applications
Applying for an ITIN, whether it's a new application or a renewal/reactivation, can be a detailed process. The IRS requires specific documentation and adherence to procedures. For individuals who are not U.S. residents, gathering and submitting the correct documents can be challenging. This is where Certified Acceptance Agents (CAAs) play a vital role. CAAs are trained and authorized by the IRS to assist with ITIN applications. They can verify your original identification documents, which eliminates the risk of mailing your sensitive documents to the IRS. itin.net partners with CAAs to offer a streamlined and secure ITIN application service.
Using a CAA can significantly simplify the process, especially for those applying from abroad. They understand the IRS requirements and can help ensure your application is complete and accurate, reducing the likelihood of delays or rejections. If you are unsure about your eligibility, the required documentation, or the process itself, consulting with a CAA or a qualified tax professional is highly recommended. The IRS also provides resources on its website, but navigating these can sometimes be complex. For detailed information on ITIN services, you can visit itin.net.
Remember, while the ITIN number itself does not expire, its usability can be affected by inactivity. Proactive management of your ITIN status, including timely tax filings or renewal when necessary, is essential for maintaining its validity for U.S. tax and financial purposes.
