You obtain an Individual Taxpayer Identification Number (ITIN) by applying directly to the IRS with Form W-7, or through an IRS-authorized Certified Acceptance Agent (CAA). An ITIN is a tax processing number issued by the Internal Revenue Service (IRS) 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 non-resident aliens who need to file a U.S. tax return, individuals claiming tax treaty benefits, or dependents/spouses of U.S. citizens or resident aliens. Understanding how can someone get an itin number is the first step for many foreign nationals planning to engage with the U.S. tax system for various reasons.
Eligibility for an ITIN
Eligibility for an ITIN is determined by your need to comply with U.S. tax laws and your ineligibility for an SSN. The IRS outlines specific circumstances under which an ITIN is issued. Generally, you will need an ITIN if you are a foreign national who has U.S. tax reporting obligations or intends to claim a tax treaty benefit. This includes:
- Non-resident aliens filing a U.S. tax return: If you are not a U.S. citizen or resident alien and you have income effectively connected with a U.S. trade or business, or you are required to file a U.S. tax return for other reasons (e.g., to claim a refund), you will likely need an ITIN.
- Individuals claiming tax treaty benefits: Even if you do not have U.S. source income, if you are a non-resident alien claiming tax treaty benefits (such as reduced withholding on U.S. source income), you must obtain an ITIN. This often involves filing a U.S. tax return (like Form 1040-NR) to report the income and claim the treaty benefit, even if no tax is due.
- Dependents and spouses of U.S. citizens or resident aliens: If you are the dependent or spouse of a U.S. citizen or resident alien and you are not eligible for an SSN, you will need an ITIN to be claimed on the U.S. citizen or resident alien's tax return. This applies even if you do not have your own income to report.
- Third-party tax preparers: Tax preparers who file U.S. tax returns on behalf of their clients may need an ITIN for their clients if the clients do not have an SSN. However, this is a function of the client's need, not the preparer's.
It is important to note that an ITIN does not provide eligibility for employment in the U.S. or entitle the holder to Social Security benefits. It is solely for tax reporting purposes. If you are eligible for an SSN, you must apply for an SSN instead of an ITIN.
Required Documentation for an ITIN Application
The IRS requires specific documentation to verify your identity and foreign status when applying for an ITIN. You must submit original documents or certified copies from the issuing agency. The most commonly accepted documents include:
- Identification: A valid passport is the preferred primary identification document. It serves as both proof of identity and foreign status.
- Alternative Documents: If you do not have a passport, or if your passport does not contain your complete name and/or date of birth, you may submit a combination of other documents. These can include:
- National identity card (must show name, photograph, current address, date of birth, and expiration date)
- Birth certificate (required for dependents under 18)
- Foreign driver's license
- Foreign voter's registration card
- Visa
- U.S. state driver's license
- U.S. Social Security card (if you have one, even if not eligible for an SSN)
- Civilan identification card for national or military record
- Health insurance card
- School records (for dependents under 18)
- Bank statement
Each document must be current (not expired) and contain your full name and photograph (except for birth certificates and school records for dependents under 18). You must provide original documents or certified copies from the issuing agency. The IRS will not accept photocopies unless they are certified by the issuing agency. If you submit original documents, the IRS will return them to you by mail, typically within 60 days. To avoid the risk of losing original documents, many applicants choose to use a Certified Acceptance Agent (CAA).
Application Methods: Direct to IRS vs. Certified Acceptance Agent (CAA)
There are two primary methods to submit your ITIN application:
1. Direct Application to the IRS
You can mail your completed Form W-7, along with original or certified copies of your identification documents and your U.S. federal income tax return, to the IRS at:
Internal Revenue Service Austin, TX 73301-0009
This method requires you to send original identification documents through the mail, which can be a concern for many applicants. The IRS processing times for direct applications can also be longer compared to using a CAA, especially during peak tax season.
2. Application Through a Certified Acceptance Agent (CAA)
A Certified Acceptance Agent (CAA) is an individual or entity (like itin.net) authorized by the IRS to assist applicants in obtaining ITINs. CAAs can:
- Verify your original identification documents: Instead of mailing your original documents to the IRS, you present them to the CAA. The CAA will examine them and send certified copies to the IRS on your behalf. This means you retain your original documents throughout the process.
- Review your application: CAAs can help ensure your Form W-7 is correctly completed and that you have all the necessary supporting documentation, reducing the chances of errors that could lead to delays or rejection.
- Forward your application: The CAA will submit your completed application package to the IRS. This can often expedite the process.
Using a CAA provides a significant advantage by eliminating the need to mail original identification documents and potentially speeding up the application review. Many individuals find this method more secure and efficient. You can find a CAA near you through the IRS website or by contacting a reputable service.
Completing Form W-7
Form W-7, Application for IRS Individual Taxpayer Identification Number, is the core document for your ITIN application. It requires accurate information to ensure proper processing. Key sections include:
- Personal Information: You must provide your full legal name, mailing address, foreign address (if applicable), date of birth, country of birth, and gender. Ensure this information exactly matches your supporting identification documents.
- Reason for Applying: You must select the reason for applying from the list provided on the form. This is crucial, as it determines your eligibility. Common reasons include needing to file a federal tax return or claim treaty benefits.
- Taxpayer Identification Number (TIN) Status: This section asks about your eligibility for an SSN and your U.S. residency status.
- Identification Document Information: You will need to provide details about the identification document you are submitting to prove your identity and foreign status.
- Attestation: You will sign and date the form, attesting to the truthfulness and accuracy of the information provided.
It is vital to complete Form W-7 accurately and thoroughly. Errors or omissions can lead to significant delays in processing or rejection of your application. If you are applying as a dependent, the application will also require information about the U.S. taxpayer claiming you, including their SSN or ITIN and signature.
Filing a U.S. Tax Return with Form W-7
For most applicants, filing Form W-7 requires the submission of a valid U.S. federal income tax return. This tax return must be filed at the same time as your Form W-7. The IRS generally requires you to file a tax return to obtain an ITIN, unless you fall under specific exceptions, such as claiming certain tax treaty benefits or being a dependent of a U.S. citizen or resident alien who is claiming you on their return.
- Non-residents with U.S. income: If you are a non-resident alien with income effectively connected with a U.S. trade or business, or U.S. source income subject to withholding, you will typically file Form 1040-NR, U.S. Nonresident Alien Income Tax Return. You would attach your completed Form W-7 and supporting documentation to this return.
- Claiming treaty benefits: If you are claiming tax treaty benefits to reduce withholding on U.S. source income, you may need to file Form 1040-NR or Form 1042-S, Foreign Person's U.S. Income Subject to Withholding, along with Form W-7.
- Dependents and spouses: If you are a dependent or spouse of a U.S. citizen or resident alien and you are not eligible for an SSN, you can submit Form W-7 directly to the IRS without filing a tax return of your own. In this case, the U.S. citizen or resident alien will claim you on their tax return and must provide their SSN or ITIN on their return.
When filing your tax return and Form W-7 together, you must include all required schedules and forms. If you are using a CAA, they can help ensure your tax return is complete and accurate before submission.
ITIN Processing Times and Costs
The IRS does not charge a fee to apply for an ITIN. However, if you use a third-party service or a Certified Acceptance Agent (CAA) that is not part of a tax preparation service, they may charge a fee for their assistance in verifying your documents and submitting your application. The cost for these services varies.
The IRS processing time for Form W-7 applications can vary significantly depending on the time of year and the volume of applications received. Generally, the IRS aims to process ITIN applications within:
- 7 to 10 weeks for applications submitted directly to the IRS service center.
- 4 to 6 weeks for applications submitted through a CAA. These are estimates, and actual processing times can be longer.
During peak tax filing season (January through April), processing times tend to be longer. It is advisable to apply well in advance of any tax deadlines to ensure you receive your ITIN in time.
Once your application is approved, the IRS will issue you an ITIN and mail a notice, CP-565, to your U.S. mailing address. This notice contains your unique ITIN. It is crucial to keep this notice and your ITIN secure, as it will be used for all future U.S. tax filings.
Common Mistakes When Applying for an ITIN
Many applicants encounter delays or rejections due to common mistakes. Being aware of these pitfalls can help ensure a smoother application process:
- Incomplete or inaccurate Form W-7: Failing to fill out all required fields, or providing incorrect information (e.g., name mismatch with ID, incorrect date of birth), is a primary reason for delays. Ensure all personal details precisely match your identification documents.
- Missing or unacceptable identification documents: Not providing the required primary identification (passport) or failing to submit acceptable alternative documents, or submitting photocopies instead of originals or certified copies, will cause your application to be rejected. Remember, if you mail original documents, they will be returned, but this can take time.
- Failure to include a U.S. tax return: Most applicants must submit a completed U.S. federal income tax return with their Form W-7. Forgetting to include this, or submitting an incomplete tax return, will result in rejection. Ensure the tax return is for the relevant tax year for which the ITIN is needed.
- Incorrectly claiming exceptions: If you believe you qualify for an exception to the tax return filing requirement (e.g., claiming treaty benefits without filing), ensure you meet all IRS criteria for that exception and provide any necessary supporting documentation.
- Mismatched information on supporting documents: If your name or date of birth differs between your identification documents, you may need to provide additional certified documents to reconcile the discrepancies.
Carefully reviewing all documentation and ensuring all fields on Form W-7 are completed accurately can prevent these common issues.
What Happens After You Get Your ITIN?
Once you receive your ITIN, it becomes your permanent tax identification number for U.S. tax purposes. You will use this number on all future U.S. tax filings. If you are a non-resident alien with U.S. business activities, you may also need an Employer Identification Number (EIN) for your business. An EIN is obtained by filing Form SS-4 with the IRS and is separate from your ITIN. This is a common next step for individuals forming a U.S. LLC or other business entities, which often require both an ITIN for the owner and an EIN for the business itself. You can learn more about obtaining an EIN on our /ein page.
If you are planning to establish a U.S. LLC, you will need to form the entity and often secure an EIN before opening a U.S. bank account. Many non-residents also find it beneficial to open a U.S. bank account to manage their business finances effectively. Services like Mercury, Relay, or Brex cater to international founders and can be explored further on our /bank-account page. The process of setting up a U.S. business often involves these interconnected steps: ITIN, EIN, and bank account.
Your ITIN may need to be renewed. The IRS requires ITIN holders to renew their ITINs periodically, typically every five years, or when their ITIN expires. If your ITIN expires, you must renew it before filing your next tax return. The renewal process is similar to the initial application, requiring Form W-7 and updated identification documents. The IRS sends out notices for ITIN renewals, and you can check the IRS website for the most current renewal requirements. Failure to renew an expired ITIN can result in delays in processing your tax returns and receiving refunds. You can find more details about ITIN renewals and related topics in our /qa section.
Seeking Assistance for Your ITIN Application
While you can apply for an ITIN directly with the IRS, many individuals benefit from seeking assistance, especially if they are unfamiliar with U.S. tax forms or documentation requirements. Certified Acceptance Agents (CAAs) are specifically trained to help applicants navigate the ITIN application process. Using a CAA like itin.net can provide peace of mind, as they can help ensure your application is complete and accurate, and they allow you to keep your original identification documents.
If your tax situation is complex, involves significant U.S. investments, or if you are unsure about your U.S. tax obligations or treaty benefits, consulting with a qualified tax professional or an international tax attorney is highly recommended. They can provide personalized advice tailored to your specific circumstances. You can learn more about our expertise at /about.
