You obtain an Individual Taxpayer Identification Number (ITIN) by applying directly to the IRS or through an IRS-authorized Certified Acceptance Agent (CAA). An ITIN is a nine-digit number assigned by the Internal Revenue Service 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 non-resident aliens filing U.S. tax returns, resident aliens filing U.S. tax returns, dependents, and children of U.S. citizens/resident aliens, and spouses of U.S. citizens/resident aliens. The process for how to obtain ITIN documents is specific and requires careful attention to detail.
Eligibility for an ITIN
Eligibility for an ITIN is determined by your need for a U.S. taxpayer identification number for tax purposes. The IRS issues ITINs to individuals who do not have an SSN and meet specific criteria. These criteria generally fall into a few main categories:
- Non-resident aliens who must file a U.S. tax return: This is the most common reason for needing an ITIN. If you are not a U.S. citizen or a U.S. resident alien but have U.S. tax obligations, you will likely need an ITIN.
- U.S. resident aliens (based on days present in the U.S.) who are not eligible for an SSN: While most resident aliens are eligible for an SSN, some may not be. If you meet the substantial presence test or the green card test for residency and cannot obtain an SSN, you may apply for an ITIN.
- Dependents or beneficiaries of U.S. citizens or resident aliens: If you are claimed as a dependent on a U.S. tax return or are a dependent who needs to file a tax return, you may need an ITIN.
- Dependents or beneficiaries of non-resident alien U.S. taxpayers: Similar to the above, if you are related to a non-resident alien who has U.S. tax obligations, you might need an ITIN.
- Spouses and dependents of U.S. citizens or resident aliens filing a U.S. tax return: Even if you are not residing in the U.S., if you are married to a U.S. citizen or resident alien and are filing a joint return, you will need an ITIN if you do not have an SSN.
- Students, professors, or researchers filing a U.S. tax return: Individuals in the U.S. on certain visa types who are required to file a U.S. tax return may need an ITIN.
It is important to note that an ITIN does not authorize you to work in the U.S. or provide eligibility for Social Security benefits.
Required Documents and Forms
The primary form for applying for an ITIN is Form W-7, Application for IRS Individual Taxpayer Identification Number. You will need to complete this form accurately and submit it with supporting documentation. The supporting documentation serves to prove both your identity and your foreign status.
Identity and Foreign Status Documentation
The IRS requires you to submit original documents or certified copies of documents from the issuing agency. These documents must establish your identity and foreign status. You can submit only one of the following documents. Each document must contain your photograph and be current (not expired):
- Passport: This is the most commonly used document. It must be valid.
- National Identity Card: This card must show your nationality, a recent photograph, name, address, date of birth, and expiration date.
- U.S. Driver's License: Must contain your name, photograph, current address, date of birth, and expiration date.
- State Driver's License: Similar requirements to a U.S. Driver's License.
- Foreign Driver's License: Must contain your name, photograph, current address, date of birth, and expiration date.
- Foreign Military Identification Card: Must contain your name, photograph, and expiration date.
- National Health Insurance Card (with photo): Must contain your name, photograph, date of birth, and expiration date.
- Foreign Voter's Registration Card: Must contain your name, photograph, and expiration date.
- Civilian I.D. Card (for dependents): Must contain your name, photograph, and expiration date.
- Visa: Must contain your name, photograph, expiration date, and entry date into the U.S.
- U.S. State Identification Card: Must contain your name, photograph, current address, date of birth, and expiration date.
- Foreign Birth Certificate: This document can be used for dependents under 18 years of age if a passport or national identity card is not available. It must have your name, date of birth, place of birth, and parents' names.
If the document you submit does not contain a U.S. address, you must also provide a U.S. address on Form W-7. If you are applying based on a tax return, the address on your tax return will be used for mailing your ITIN.
Tax Return Requirement
Generally, you must be filing a U.S. federal income tax return to receive an ITIN. You will need to attach a completed tax return to your Form W-7 application. There are exceptions, such as for individuals claiming tax treaty benefits or those required to file Form 5472 for reporting transactions with a foreign-owned U.S. LLC. If you are applying under an exception, you must provide documentation supporting that exception.
How to Apply for an ITIN
There are three main ways to apply for an ITIN:
- Mail Your Application to the IRS: You can mail your completed Form W-7, along with your original or certified copies of identity and foreign status documents, and your U.S. federal income tax return (or documentation for an exception) to the IRS address listed in the Form W-7 instructions. This is the most common method.
- Apply Through a Certified Acceptance Agent (CAA): This is often the most convenient method. A CAA is an individual or entity authorized by the IRS to help taxpayers apply for ITINs. CAAs can verify your original documentation and forward your application to the IRS. This means you do not have to mail your original identification documents, as the CAA will return them to you after verification. itin.net is an authorized CAA, offering a streamlined process for obtaining your ITIN.
- Apply at an IRS Taxpayer Assistance Center (TAC): Some IRS TACs offer ITIN application services by appointment. You must call to schedule an appointment and bring your original documentation and tax return. However, not all TACs provide this service, and wait times can be long.
Applying via Mail
If you choose to mail your application, ensure all documents are present and accurate. Incorrect or incomplete applications are the leading cause of delays. You must include:
- A completed and signed Form W-7.
- Your original or certified copies of identity and foreign status documents.
- A federal income tax return (unless you qualify for an exception).
Mail these to:
Internal Revenue Service Austin, TX 73301-0009 USA
Be aware that you will be without your original documents for the entire processing time, which can be several weeks.
Applying via Certified Acceptance Agent (CAA)
Using a CAA like itin.net can significantly simplify the process. The CAA will:
- Assist you in completing Form W-7.
- Verify your original identification documents and foreign status documents.
- Review your tax return for completeness.
- Forward your complete application package to the IRS.
The key benefit here is that the CAA handles the verification of your original documents, meaning you get them back immediately after they are reviewed. This avoids the risk of loss or delay associated with mailing them to the IRS. The CAA then submits the application on your behalf, often resulting in a quicker overall turnaround time.
Processing Times and Costs
The IRS does not charge a fee to apply for an ITIN. However, if you use a third-party service, such as a Certified Acceptance Agent, they may charge a fee for their services. The cost for using a CAA varies by provider.
Processing times for ITIN applications can vary significantly. As of recent IRS guidelines, the typical processing time is as follows:
- Applications received by mail: 7 to 11 weeks.
- Applications processed through a CAA: 5 to 8 weeks.
- Applications processed at a Taxpayer Assistance Center (TAC): 4 to 6 weeks (appointments are limited).
These timelines are estimates and can be longer during peak tax seasons or if the application is incomplete or requires further review. It is advisable to apply well in advance of any tax deadlines.
Common Mistakes to Avoid
Understanding how to obtain ITIN documents also involves knowing common pitfalls. Mistakes can lead to significant delays or even rejection of your application. Key errors include:
- Incomplete Form W-7: Missing signatures, incorrect personal information (name, address, foreign tax ID number if applicable), or failure to fill out all required fields.
- Incorrect or Expired Identification Documents: Submitting documents that are not on the IRS-approved list, are expired, or do not contain all necessary information (like a photograph).
- Failure to Submit a Tax Return: Forgetting to include a valid U.S. federal income tax return when required, or not providing documentation to support an exception to this rule.
- Not Sending Original or Certified Documents: Mailing photocopies instead of original documents or certified copies from the issuing agency when applying by mail. CAAs handle this verification, but if applying directly, this is critical.
- Incorrectly Claiming Tax Treaty Benefits: If applying based on tax treaty benefits, failing to correctly identify the treaty article and provide the necessary supporting documentation.
- Not Including Supporting Documentation for Exceptions: If you are not filing a tax return, ensure you have the correct documentation to prove your eligibility under an exception, such as for foreign-owned U.S. LLC reporting with Form 5472.
What Happens After You Receive Your ITIN?
Once your ITIN application is approved, the IRS will mail you a Form W-7 confirmation letter with your assigned ITIN. This letter is often referred to as a CP-565 notice. You should keep this letter and your ITIN in a safe place, as you will need it for all future U.S. tax filings.
Your ITIN is permanent and does not expire. However, the IRS may require you to renew your ITIN if it has not been used on a federal tax return for three consecutive tax years, or if your ITIN falls within a range designated for renewal. The IRS will notify you if your ITIN needs renewal, typically through notices like CP-48 or CP-575.
If you are planning to establish a business in the U.S., such as a U.S. LLC, you will likely need an EIN in addition to your ITIN. An EIN is required for most business entities. You can apply for an EIN separately using Form SS-4.
Furthermore, if your business activities in the U.S. require opening a U.S. bank account, an ITIN can sometimes be used in conjunction with other documentation, though an EIN is often preferred or required by banks for business accounts. Services like Mercury, Relay, or Brex may have specific requirements for non-residents. Opening a U.S. bank account is a critical step for many foreign nationals conducting business in the U.S.
Getting Help with Your ITIN Application
Applying for an ITIN can be a complex process, especially for those unfamiliar with U.S. tax forms and documentation requirements. The IRS provides resources, but navigating the system can be challenging.
Certified Acceptance Agents (CAAs)
As mentioned, CAAs are your best resource for a smooth ITIN application. They are trained by the IRS to help you with the process, verify your documents, and submit your application. Using a CAA like itin.net can save you time and the anxiety of handling sensitive personal documents. They can also help ensure your application is complete and accurate, reducing the chance of delays.
IRS Resources
The IRS website offers publications and instructions for Form W-7. You can also find information on ITIN renewal and exceptions to the tax return filing requirement. Taxpayer Assistance Centers (TACs) can offer in-person assistance, but appointments are often difficult to secure.
Professional Tax Assistance
For complex tax situations, such as those involving international tax treaties, significant foreign income, or specific business structures like a U.S. LLC, consulting with a qualified tax professional or an international tax attorney is highly recommended. They can provide tailored advice based on your unique circumstances and ensure compliance with all U.S. tax laws.
