An ITIN, or Individual Taxpayer Identification Number, is a 9-digit number issued by the Internal Revenue Service (IRS). It follows a specific format: XXX-XX-XXXX. The first three digits range from 70 to 88, 89, 90–92, 93–99, or 50–65. The fourth and fifth digits are always 00. The last four digits are a randomly assigned sequence.
The Purpose of an ITIN
The primary purpose of an ITIN is to allow individuals who are not eligible for a Social Security Number (SSN) to comply with U.S. tax laws. This includes non-resident aliens filing U.S. tax returns, resident aliens filing U.S. tax returns, dependent or spouse claiming tax benefits, or a dependent/spouse of a U.S. citizen/resident alien. Without an ITIN, these individuals cannot file U.S. tax returns or claim certain tax benefits, potentially leading to penalties and interest.
How ITINs Are Formatted
As mentioned, an ITIN is a nine-digit number. The IRS issues these numbers in a specific structure to distinguish them from Social Security Numbers. The format is always XXX-XX-XXXX. The first three digits are not sequential and are assigned in specific ranges, such as 70-88, 89, 90-92, 93-99, or 50-65. The crucial distinguishing feature is that the fourth and fifth digits are always 00. This pattern is unique to ITINs. The final four digits are a randomly generated sequence.
Who Needs an ITIN?
An ITIN is for individuals who have U.S. tax obligations but cannot obtain an SSN. This typically includes:
- Non-resident aliens who are required to file a U.S. tax return or claim a tax treaty benefit.
- Resident aliens (based on days present in the U.S.) who are required to file a U.S. tax return or claim a tax treaty benefit, but are not eligible for an SSN.
- Dependents or spouses of U.S. citizens or resident aliens who need to be claimed on a U.S. tax return, even if they do not have an SSN.
- Individuals who need to open a U.S. bank account or establish other financial relationships in the U.S. that require a U.S. taxpayer identification number. While not strictly required for all bank accounts, some financial institutions request it.
- Individuals seeking to obtain an Employer Identification Number (EIN) for a business entity, though an EIN is usually obtained for the business itself, not the individual owner directly for that purpose. However, an ITIN can be used by foreign individuals to apply for an EIN for their U.S. business.
Applying for an ITIN
To obtain an ITIN, you must submit Form W-7, Application for IRS Individual Taxpayer Identification Number. You cannot apply for an ITIN online. The application requires original or certified copies of identification documents and proof of foreign status. Accepted documents include passports, national identification cards, birth certificates, and driver's licenses. The IRS has specific requirements for these documents, and it's essential to provide them correctly to avoid delays.
There are three primary ways to submit your Form W-7:
- Mail: You can mail your completed Form W-7, along with original or certified copies of your identification documents and a federal tax return, to the IRS address listed on the form. This method can take several weeks to months for processing.
- IRS Taxpayer Assistance Centers (TACs): Some IRS TACs offer in-person ITIN application services. You can schedule an appointment to have your documents verified. However, not all TACs provide this service, and it requires booking well in advance.
- Certified Acceptance Agents (CAAs): This is often the most convenient and secure method. CAAs are individuals or entities (like itin.net) authorized by the IRS to help you apply for an ITIN. They can verify your original identification documents and forward your application to the IRS. Using a CAA means you don't have to send original documents through the mail, as the CAA authenticates them for you.
What Does an ITIN Number Look Like in Practice?
When you receive your ITIN from the IRS, it will be issued on a notice, typically Notice CP-565. This notice will clearly state your nine-digit ITIN. For example, if your ITIN is 72-34-5678, it will appear as such on official IRS correspondence. It's crucial to keep this notice in a safe place, as you will need your ITIN for all future tax filings and interactions with the IRS. You will also need it if you plan to establish a U.S. LLC or open a U.S. bank account.
ITIN vs. SSN
While both ITINs and SSNs are nine-digit taxpayer identification numbers, they serve different purposes and have different issuing authorities. SSNs are issued by the Social Security Administration (SSA) and are primarily for individuals authorized to work in the United States. An ITIN, on the other hand, is issued by the IRS and is for tax purposes only; it does not grant work authorization. An ITIN will never be used for employment verification or to establish eligibility for Social Security benefits. The formatting is also distinct, with SSNs having a different structure and issuing ranges than ITINs.
Renewal and Expiration
Previously, ITINs did not expire. However, the IRS implemented a renewal program for ITINs that have not been used on a federal tax return for three consecutive filing years. If your ITIN falls into this category, you may need to renew it. The IRS typically notifies individuals if their ITIN is due for renewal. The renewal process is similar to the initial application, requiring Form W-7 and supporting identification documents. It is important to check your ITIN status periodically, especially if you have not filed a U.S. tax return in several years.
ITINs and U.S. Business Formation
For foreign nationals looking to establish a U.S. business, an ITIN can be a critical first step. It can be used to apply for an Employer Identification Number (EIN) by submitting Form SS-4. An EIN is essential for operating a business in the U.S., opening business bank accounts, and hiring employees. If you are forming a U.S. LLC, you will likely need an EIN. Furthermore, having an ITIN can sometimes facilitate opening a U.S. bank account, though this depends on the specific bank's policies. Some banks may also require an EIN for business accounts.
Common Misconceptions About ITINs
Several common misconceptions surround ITINs. One is that an ITIN grants work authorization, which is false. Another is that an ITIN is the same as an SSN; they are distinct in purpose and issuance. Some individuals also believe their ITIN will automatically expire if not used annually, but the IRS renewal policy specifically targets ITINs unused for three consecutive tax years. Understanding what an ITIN number looks like and its precise function is key to avoiding these errors.
Next Steps After Receiving Your ITIN
Once you receive your ITIN, you can use it to file your U.S. federal tax return. If you are filing a tax return as a non-resident alien, you will likely be filing Form 1040-NR. If you are establishing a U.S. business, you can now proceed with obtaining an EIN using Form SS-4. For those forming a U.S. LLC, you'll need to ensure you have a registered agent and an Operating Agreement, and then apply for an EIN. Opening a U.S. bank account for your business will also be a subsequent step.
