You apply for an ITIN by submitting Form W-7, Application for IRS Individual Taxpayer Identification Number, along with original or certified copies of identification documents and a U.S. federal tax return. This process is for individuals who are not eligible for a Social Security Number (SSN) but have a U.S. tax filing requirement or need to claim a tax treaty benefit. Understanding how to apply for an ITIN US is the first step for many foreign nationals engaging with the U.S. tax system.
Who is Eligible for an ITIN?
Eligibility for an ITIN is determined by the IRS based on specific criteria. You must be a foreign national or other alien individual who is not eligible for an SSN and meets one of the following conditions:
- You are a non-resident alien filing a U.S. federal tax return.
- You are a resident alien (based on days present in the U.S.) filing a U.S. federal tax return.
- You are filing a U.S. federal tax return with a spouse or dependent who is eligible for an ITIN.
- You are the dependent or spouse of a U.S. citizen or resident alien filing a U.S. federal tax return.
- You are a non-resident alien claiming tax treaty benefits on U.S. income.
- You are an alien filing a U.S. tax return under Section 6013(g) (election to be treated as resident alien).
It is important to note that simply having a U.S. bank account or planning to form a U.S. LLC does not automatically grant ITIN eligibility if there is no accompanying U.S. tax obligation or treaty claim. An Employer Identification Number (EIN) is for business entities, not individuals seeking an ITIN. If you are forming a U.S. LLC, you may eventually need an EIN, but your ITIN application is separate and based on individual tax requirements.
Required Documentation for Form W-7
To successfully apply for an ITIN, you must provide specific documentation to the IRS. The core requirements are:
- Completed Form W-7: Ensure all sections are filled out accurately and completely. Sign and date the form. Do not leave any fields blank unless instructed. If you are applying as an individual, you will use the "Individual" section. If applying on behalf of a dependent, you will use the "Dependent" section.
- Original or Certified Copies of Identification Documents: You need to prove your identity and foreign status. The IRS accepts a combination of documents, but generally requires one primary identification document and one document supporting foreign status. Primary documents include:
- Passport (most commonly used and recommended)
- National Identity Card (must show name, photograph, address, date of birth, and expiration date)
- U.S. Driver's License
- Foreign Driver's License
- U.S. State ID Card
- Foreign Voter's Registration Card
- Civil Birth Certificate (for dependents under 18)
- National Health Insurance Card (Mexico) / Tarjeta Sanitaria (Spain)
- Foreign Military Identification Card
- U.S. Military ID Card
- Visa
Secondary identification documents can include: * Bank Statement * Medical Records (for dependents under 6) * School Records (for dependents under 18) * Utility Bills (showing name and address) * Foreign Driver's License (if not used as primary) * U.S. State and Local Identification Cards (if not used as primary)
All documents must be current and valid. If submitting original documents, the IRS may mail them back to you, which can take several weeks. Submitting certified copies from the issuing agency or a designated acceptance agent can be safer and faster.
- Original U.S. Federal Tax Return: You must attach a completed and signed U.S. federal income tax return to your Form W-7. The only exceptions are for those applying under specific circumstances like claiming tax treaty benefits without a filing requirement, or if you are applying for an ITIN for a dependent or spouse.
How to Submit Your ITIN Application
There are three primary methods for submitting your Form W-7 application:
Mail to the IRS: You can mail your completed Form W-7, supporting identification documents, and your U.S. federal tax return directly to the IRS at the following address: Internal Revenue Service Austin, TX 73301-0009 USA This method requires you to mail original documents or certified copies, and it generally has the longest processing time. The IRS will review your application and, if approved, will mail you your ITIN. They will also forward your tax return to the appropriate service center for processing.
Apply Through a Certified Acceptance Agent (CAA): This is often the most convenient and secure method. Certified Acceptance Agents are individuals or entities authorized by the IRS to help taxpayers apply for ITINs. They are trained by the IRS and can verify your original identification documents or certified copies and forward your application package to the IRS on your behalf. The benefit of using a CAA is that they can authenticate your documents, meaning you do not have to mail your original passports or other vital identification to the IRS. This significantly reduces the risk of loss or delay. itin.net works with CAAs to facilitate this process for you.
Visit an IRS Taxpayer Assistance Center (TAC): Some IRS Taxpayer Assistance Centers offer ITIN application services. You can make an appointment at a TAC to have your documentation verified. However, not all TACs provide this service, and availability can be limited. You must call to schedule an appointment and confirm that the specific center offers ITIN application assistance.
Each method has its own advantages and disadvantages regarding processing time, document security, and convenience. For many non-residents and foreign nationals, the CAA route offers the best balance.
Processing Times and Costs
The IRS does not charge a fee to apply for an ITIN. However, if you use a service like itin.net or another CAA, there may be service fees associated with their assistance. These fees cover the expertise and convenience provided by the agent.
IRS processing times for Form W-7 can vary significantly. Currently, the IRS estimates the following processing windows:
- Standard Processing: Approximately 7 to 11 weeks after the IRS receives your application. This timeframe can be longer during peak tax seasons (January to April) or if there are errors in your application.
- Expedited Processing: The IRS offers expedited processing in certain cases, such as if you have an urgent need to file your tax return or claim a tax treaty benefit. Expedited processing can reduce the wait time to 5 to 7 weeks, but it may require additional documentation or justification. You can request expedited processing by phone or through a CAA.
It's crucial to apply well in advance of any tax deadlines to allow ample time for processing. If you are planning to establish a U.S. LLC and need an EIN, that process is separate and typically takes less time, especially if you apply online directly with the IRS.
Common Mistakes and How to Avoid Them
Several common mistakes can lead to delays or rejections of your ITIN application. Being aware of these pitfalls can help ensure a smoother process:
- Incomplete or Incorrectly Completed Form W-7: Ensure every field is accurately filled out. Double-check names, addresses, and Social Security Number (if applicable, though usually this is where you indicate you are not eligible). Missing signatures or dates are also common errors.
- Missing or Invalid Identification Documents: Providing expired documents, photocopies instead of originals or certified copies, or not including the required primary and secondary documents can cause delays. Ensure your documents are valid and meet IRS requirements.
- Unsigned Tax Return: If your ITIN application requires an attached tax return, ensure it is signed by the applicant. An unsigned tax return will result in your W-7 being rejected.
- Incorrectly Certified Copies: If you are not using a CAA and are obtaining certified copies from the issuing agency, ensure they are properly certified according to the agency's procedures.
- Not Attaching the Tax Return (When Required): For most applicants, a tax return must be attached. If you forget to include it, or if it's not the correct version (e.g., amended return when an original is needed), your application will be delayed or denied.
- Applying for an ITIN Without a Tax Filing Requirement: Remember that an ITIN is primarily for tax purposes. While it can facilitate opening a U.S. bank account, it is not granted solely for that purpose. You must have a valid reason related to U.S. tax law.
By carefully reviewing your application and supporting documents before submission, you can significantly reduce the chances of encountering these issues.
What Happens After You Receive Your ITIN?
Once your ITIN application is approved, the IRS will mail you a CP565 notice, which officially assigns your ITIN. This notice is important for your records.
- Filing Future Tax Returns: You will use this ITIN on all future U.S. federal tax returns. If you are required to file Form 5472 for a U.S. LLC you own, your ITIN will be used on that form as well.
- Banking and Business: Your ITIN can be used to open a U.S. bank account, which is a common requirement for foreign nationals operating businesses or investing in the U.S. Services like Mercury, Relay, or Brex may require an ITIN or EIN for account opening, depending on the business structure.
- ITIN Renewal: ITINs are valid for seven years from the date of issuance. If your ITIN has expired, or if you have not used it on a federal tax return for three consecutive tax years, you will need to renew it by submitting Form W-7 and a tax return. The IRS sends out notices (like CP48) when an ITIN is nearing expiration or has expired.
- Other Tax Filings: Depending on your U.S. financial activities, you may have other filing requirements. For example, if you are a foreign owner of a U.S. disregarded entity or partnership, you may need to file Form 5472 and potentially Form 1040-NR (for non-resident aliens). Ensure you understand all your U.S. tax obligations.
