You obtain an Individual Taxpayer Identification Number (ITIN) by applying directly to the IRS using Form W-7, Application for IRS Individual Taxpayer Identification Number. This process is necessary for foreign nationals and other non-residents who have U.S. tax reporting obligations but do not have and are not eligible for a Social Security number (SSN). Understanding how to obtain an ITIN is the first step for many individuals engaging with the U.S. tax system for the first time.
Who Needs an ITIN?
An ITIN is required for individuals who need a U.S. taxpayer identification number for tax purposes but are not eligible for an SSN. This includes:
- Non-resident aliens filing a U.S. federal income tax return (e.g., Form 1040-NR).
- Resident aliens (based on days present in the U.S.) filing a U.S. federal income tax return, who are not eligible for an SSN.
- Dependents or a spouse of a U.S. citizen or resident alien filing a U.S. tax return.
- Dependents or a spouse of a U.S. citizen or resident alien filing a U.S. tax return, even if they do not file a return themselves.
- Non-resident alien beneficiaries or participants in U.S. trusts, estates, or U.S. partnership.
- Individuals with U.S. tax filing or reporting requirements, such as those receiving certain U.S. source income, owning U.S. real property, or meeting other specific IRS criteria.
An ITIN is for tax purposes only and does not authorize employment in the U.S. or provide eligibility for Social Security benefits. The process for how to obtain an ITIN is specifically designed for these tax-related needs.
Eligibility Requirements for an ITIN
To be eligible for an ITIN, you must be required to have a U.S. taxpayer identification number and meet one of the following criteria:
- You are a non-resident alien who is not eligible for an SSN and must file a U.S. tax return.
- You are a U.S. citizen or resident alien who is not eligible for an SSN (this is rare and usually involves specific religious objections).
- You are a dependent or claimed as a dependent on a U.S. tax return, and you do not have an SSN.
- You are a spouse of a U.S. citizen or resident alien, and you do not have an SSN.
It's crucial to understand that an ITIN is not a substitute for an SSN. If you become eligible for an SSN, you must apply for one and stop using your ITIN for tax purposes.
Documents Required for an ITIN Application
To apply for an ITIN, you must submit Form W-7 along with original or certified copies of documents proving your identity and foreign status. The IRS requires specific documentation to verify your identity and country of citizenship. You must provide:
- Completed Form W-7: Ensure all sections are filled out accurately. Attach it to your tax return if you are filing one concurrently.
- Original U.S. Federal Income Tax Return: Unless you qualify for an exception, you must file a tax return with your ITIN application. This is the primary reason for needing the ITIN.
- Original or Certified Copy of Foreign Status and Identity Documents: You must provide one original document from the following list that contains your photograph, name, current address, and date of birth:
- Passport
- National Identity Card (must have a photo, name, address, DOB, and expiration date)
- U.S. Driver's License
- Civil Birth Certificate (for dependents under 18)
- Foreign Driver's License
- National Health Insurance Card (U.S. or foreign)
- State-issued I.D. Card
- Foreign Military Identification Card
- U.S. Military I.D. Card
- Visa
- Alien Registration Card
In addition to the primary document, you may need a secondary document to prove foreign status if the primary document does not contain both identity and foreign status information. Examples include a foreign driver's license or a U.S. state-issued ID card along with a foreign birth certificate.
The IRS will return your original documents by mail after verifying them, which can take up to 60 days. If you are concerned about mailing original documents, you can use the services of a Certified Acceptance Agent (CAA), such as those offered by itin.net. CAAs are designated by the IRS to help individuals apply for ITINs and can verify your original documents on your behalf, returning them to you immediately. This is a significant advantage of using a CAA.
How to Apply for an ITIN: Step-by-Step
There are three primary ways to submit your Form W-7 application:
Mail Your Application to the IRS: You can mail your completed Form W-7, your U.S. federal income tax return, and your original or certified copies of identity and foreign status documents to the IRS address listed in the Form W-7 instructions (currently Austin, TX). This method requires patience, as it involves mailing sensitive original documents and waiting for IRS processing.
Apply Through a Certified Acceptance Agent (CAA): This is often the most convenient method. You can visit an authorized CAA, present your original identification documents, and have them certified. The CAA will then forward your application package to the IRS on your behalf. The benefit here is that the CAA verifies your documents and returns them to you on the same day. This significantly reduces the risk of losing your original documents during transit. Many individuals find this route to be the most straightforward way to get their ITIN.
Apply at an IRS Taxpayer Assistance Center (TAC): Some IRS TACs offer ITIN application services by appointment. You can schedule an appointment online or by calling the IRS. You will need to bring your original documentation and completed Form W-7 to the appointment. However, not all TACs provide this service, and appointment availability can be limited. It is advisable to call ahead or check the IRS website to confirm availability and services at your local TAC.
Regardless of the method chosen, ensure your Form W-7 is complete and accurate. Incomplete applications are a common reason for delays or rejections. If you are filing a tax return concurrently, ensure it is also complete and accurate. The IRS generally processes ITIN applications within a few weeks, but this can extend during peak tax season.
Processing Times and Costs
There is no fee charged by the IRS to apply for an ITIN. However, if you use the services of a Certified Acceptance Agent (CAA), they may charge a fee for their assistance in verifying your documents and processing your application. The cost for CAA services varies by provider.
IRS processing times for ITIN applications can fluctuate. Generally, you can expect:
- Routine Applications: 7 to 10 weeks from the date the IRS receives your application.
- During Peak Tax Season (January to April): Processing times can extend to 11 weeks or more due to high volume.
- Applications with Tax Returns: If you file your tax return with your Form W-7, the processing time includes the time it takes for the IRS to process your tax return as well.
These timelines are estimates and can be affected by various factors, including the completeness of your application, the volume of applications the IRS is receiving, and any potential discrepancies in your documentation. The IRS publishes estimated processing times on its website, which can be a useful resource.
Common Mistakes When Applying for an ITIN
Several common errors can lead to delays or outright rejection of your Form W-7 application. Being aware of these pitfalls can save you considerable time and frustration when you are trying to figure out how to obtain an ITIN:
- Incomplete or Inaccurate Form W-7: Missing information, incorrect names, or improperly formatted addresses are frequent issues. Double-check every field before submitting.
- Missing or Incorrect Documentation: Failing to provide all required documents, submitting photocopies instead of originals or certified copies, or providing documents that do not meet the IRS criteria (e.g., expired IDs, documents without photos) will cause problems.
- Not Filing a Tax Return: Most applicants must file a U.S. federal income tax return with their Form W-7. If you are not filing a return and do not meet one of the specific exceptions, your application will be rejected.
- Incorrect ITIN Status: Applying for an ITIN when you are eligible for an SSN is a common mistake. If you can get an SSN, you must apply for one instead.
- Mailing Original Documents Without Tracking: If you mail your application directly to the IRS, ensure you use a mailing service that provides tracking and insurance. Losing original documents can be a significant setback.
- Using Expired Documents: Ensure all identification documents are current and valid at the time of application.
Carefully reviewing the Form W-7 instructions and gathering all necessary documents beforehand is critical to avoid these common mistakes.
What Happens After You Receive Your ITIN?
Once your ITIN application is approved, the IRS will mail you a Form CP-565, ITIN Assignment Letter. This letter contains your unique ITIN. Keep this document in a safe place, as you will need it for future tax filings and other U.S. tax-related purposes.
Your ITIN is permanent and does not expire, but you must use it on your tax return at least once every three consecutive tax years. If you do not file a U.S. tax return using your ITIN for three consecutive years, the IRS may revoke it. If your ITIN is revoked and you subsequently need one, you will have to reapply.
If you plan to establish a U.S. business, your ITIN can be a stepping stone. For instance, you might need an ITIN to apply for an Employer Identification Number (EIN) for your U.S. LLC, which is a prerequisite for opening a U.S. bank account or conducting business in the U.S. Companies like Mercury, Relay, or Brex often require an EIN and a U.S. address for account opening. Understanding the relationship between ITINs, EINs, and business formation is key for foreign nationals looking to operate in the U.S. The process for forming a U.S. LLC typically involves obtaining an EIN and a registered agent, which can be facilitated through services like itin.net.
