Foreign nationals can obtain an Individual Taxpayer Identification Number (ITIN) by applying directly to the IRS or through an authorized Certified Acceptance Agent (CAA). The ITIN is a tax processing number issued by the Internal Revenue Service (IRS) for certain nonresident and resident aliens, their spouses, and dependents who cannot get a Social Security number (SSN). It is essential for fulfilling U.S. tax obligations, such as filing federal tax returns, when an SSN is not available. Understanding how to get an ITIN number as a foreigner involves several key steps and requirements, primarily centered around proving your identity and foreign status to the IRS. The application process, while straightforward, requires careful attention to detail to ensure timely processing and approval. This guide will walk you through the entire procedure, from determining eligibility to submitting your application and understanding what to expect afterward.
Eligibility for an ITIN
You are generally eligible for an ITIN if you have U.S. tax processing or filing requirements and do not have and are not eligible to obtain an SSN. This includes a wide range of situations for foreigners:
- Nonresident aliens filing a U.S. federal tax return: This is the most common reason. If you have U.S. source income and are required to file a U.S. tax return (e.g., Form 1040-NR), you will need an ITIN.
- Resident aliens filing a U.S. federal tax return: If you are considered a resident alien for tax purposes but cannot obtain an SSN.
- Dependents or spouses of U.S. citizens or resident aliens: If you are a dependent or spouse of a U.S. taxpayer and you cannot get an SSN, you may need an ITIN to be claimed on their tax return.
- Dependents or spouses of nonresident alien U.S. visa holders: Similar to the above, if you are a dependent or spouse and do not qualify for an SSN.
- Individuals seeking to claim tax treaty benefits: Some tax treaties allow for reduced withholding on certain types of U.S. income. To claim these benefits, you often need an ITIN.
- Nonresident aliens who are beneficiaries of an estate or trust, or partners in a partnership, or shareholders in an S corporation: These entities may have reporting requirements that necessitate an ITIN for foreign individuals involved.
- Individuals who are required to have a U.S. Taxpayer Identification Number for other tax purposes: This can include situations related to U.S. business ownership, such as needing an ITIN to file Form 5472 for a U.S. LLC if you are a foreign owner. If you are considering forming a U.S. LLC, you will likely need an ITIN to manage your tax obligations related to it. You can learn more about forming a U.S. LLC and related tax requirements at /llc.
- Individuals applying for an EIN: While an EIN is for businesses, individuals applying for an EIN on behalf of a U.S. business may sometimes be asked for their personal ITIN if they do not have an SSN. You can learn more about obtaining an EIN, the Employer Identification Number, at /ein.
It is important to note that an ITIN is solely for tax purposes. It does not authorize employment in the United States, nor does it grant eligibility for Social Security benefits. It also does not change your immigration status.
Required Documentation for ITIN Application
To successfully apply for an ITIN, you must provide original or certified copies of documents that verify your identity and foreign status. The IRS requires these documents to process your application. The primary form for applying is Form W-7, Application for IRS Individual Taxpayer Identification Number. The documentation requirements are strict to prevent fraud and identity theft. You must submit the following:
Completed Form W-7: Ensure all sections are accurately filled out. Any missing information can delay processing.
Original or Certified Copy of your U.S. Federal Tax Return: This is a critical requirement. You cannot apply for an ITIN without having a tax return to file, unless you qualify for an exception.
- Exceptions: Certain exceptions allow you to apply for an ITIN without an attached tax return. These include:
- Individuals claiming tax treaty benefits (attach Form W-7 with Form 8833, Treaty-Based Return Position Disclosure).
- Individuals required to file a tax return due to income from a U.S. real property interest.
- Dependents or spouses of U.S. citizens or resident aliens.
- Individuals who are beneficiaries of an estate or trust.
- Individuals who are partners in a partnership or shareholders in an S corporation.
- Individuals who have specific reporting requirements for U.S. accounts or entities, such as those related to a U.S. LLC.
- Documentation for Exceptions: For these exceptions, you will need to provide documentation supporting your specific situation, such as a letter from the entity, proof of U.S. real property interest ownership, or proof of relationship for dependents/spouses.
- Exceptions: Certain exceptions allow you to apply for an ITIN without an attached tax return. These include:
Original or Certified Copy of Your Identity Document: You must present one of the following documents that includes your photograph, name, current address, and date of birth:
- Passport
- National Identity Card (must show name, photograph, date of birth, expiration date)
- U.S. Driver's License
- Civil Birth Certificate (for dependents under 18)
- Foreign Driver's License
- U.S. State Driver's License
- Foreign Military Identification Card
- U.S. Military Identification Card
- Visa
- I.D. card for resident aliens (Green Card)
- Alien Registration Card
Original or Certified Copy of Your Foreign Status Document: In addition to an identity document, you must provide a document proving your foreign status. This is often the same document (e.g., a passport). If the identity document does not prove foreign status, you must submit a second document that does.
Important Notes on Documentation:
- Originals vs. Certified Copies: If you mail your application, you must send original documents or certified copies from the issuing agency. The IRS will return original documents, but this can take several weeks. Alternatively, you can have your documents verified by a Certified Acceptance Agent (CAA), which is often a more convenient and secure option. / is an example of a service that can help with this process.
- Expired Documents: Expired identity documents are generally not accepted, with some exceptions for dependents under 18 or if the document is expired but still valid for establishing identity and immigration status.
- Documentation for Dependents: For dependents under 18, a civil birth certificate is acceptable as both an identity and foreign status document. If the birth certificate does not show the applicant's name, a second identification document is required.
How to Apply for an ITIN
There are three primary methods for applying for an ITIN:
Mail Your Application to the IRS: You can mail your completed Form W-7, your original or certified tax return, and supporting documentation to the IRS address listed in the Form W-7 instructions. The IRS will process your application and mail your ITIN and original documents back to you. This method can be time-consuming due to mail transit and IRS processing times.
Apply Through a Certified Acceptance Agent (CAA): This is often the preferred method for many applicants. CAAs are individuals or entities authorized by the IRS to assist applicants in obtaining ITINs. When you apply through a CAA, you can present your original identification documents to them, and they will verify them on behalf of the IRS. This means you do not have to send your original documents to the IRS, reducing the risk of loss or delay. The CAA will then forward your completed Form W-7, your tax return, and their certification of your documents to the IRS. Using a CAA can streamline the process and provide peace of mind. Many reputable tax preparation firms and some financial institutions act as CAAs. / is a service that can assist you in finding and working with a CAA.
Apply at an IRS Taxpayer Assistance Center (TAC): Some IRS Taxpayer Assistance Centers offer ITIN application services by appointment. You can bring your Form W-7, tax return, and original or certified documentation to the TAC. However, not all TACs provide this service, and appointments can be difficult to secure. You must call the IRS at 800-829-1040 to schedule an appointment and confirm that the TAC can assist you. It is highly recommended to call ahead as services and availability vary greatly by location and time.
Regardless of the method chosen, ensure your application is complete and accurate. Incomplete applications are the most common reason for delays or rejections. The process of how to get an ITIN number as a foreigner can be managed efficiently if you follow these steps carefully.
ITIN Processing Times and Costs
There is no fee charged by the IRS to apply for an ITIN. Form W-7 applications are processed free of charge. However, you may incur costs if you use a third-party service or a Certified Acceptance Agent (CAA) to assist you with your application. These services may charge a fee for their assistance, but this is separate from any IRS processing fees, as there are none.
Processing times can vary significantly depending on the method of application, the volume of applications the IRS is receiving, and the accuracy and completeness of your submission.
- Mail-in Applications: Typically take the longest. You can expect processing times of anywhere from 8 to 11 weeks from the date the IRS receives your complete application. This timeframe includes the time it takes for the IRS to mail back your original documents.
- Certified Acceptance Agent (CAA) Applications: Generally processed faster because CAAs submit applications directly to a dedicated IRS ITIN unit. While the IRS aims to process these applications within 7 to 10 weeks, this can fluctuate.
- Taxpayer Assistance Center (TAC) Appointments: Processing times at TACs can vary, but they often aim for similar timelines as CAAs, typically within 7 to 10 weeks, assuming all documentation is in order at the time of your appointment.
Important Considerations:
- Peak Seasons: During tax season (January through April), processing times tend to be longer due to the high volume of applications and tax returns being filed.
- Accuracy: An incomplete or inaccurate application can lead to significant delays, as the IRS will need to contact you for clarification or return your application for correction.
- IRS Communication: You will receive a notice from the IRS, typically Letter 147C, when your ITIN has been assigned. This notice will contain your ITIN. If you applied through a CAA, they may also notify you. If you applied with a tax return, your ITIN will be on that return once processed.
Common Mistakes When Applying for an ITIN
Many applicants encounter delays or rejections due to common mistakes. Being aware of these pitfalls can significantly improve your chances of a smooth application process. Understanding how to get an ITIN number as a foreigner means avoiding these frequent errors:
- Incomplete or Inaccurate Form W-7: This is the most frequent issue. Ensure every field is completed accurately. Double-check names, addresses, dates, and identification numbers. Missing signatures or incorrect tax return information are common.
- Not Submitting a Valid Tax Return: Unless you qualify for a specific exception, your Form W-7 must be submitted with a valid U.S. federal tax return. Applicants often try to get an ITIN without having a tax filing requirement, which is not permitted.
- Incorrect or Missing Supporting Documentation: Failing to provide the required original or certified documents for identity and foreign status is a common problem. Ensure the documents meet IRS specifications, including being current and legible.
- Sending Expired Documents: The IRS generally requires valid, unexpired identification documents. Using an expired passport or driver's license will likely lead to rejection.
- Not Certifying Documents Properly (for CAAs): If you are using a CAA, ensure they are properly certifying your documents. If you are submitting certified copies yourself, make sure they are certified by the issuing agency (e.g., the country that issued your passport).
- Forgetting to Sign and Date the Form W-7: A simple oversight, but failing to sign and date the form will result in it being returned.
- Mailing Original Documents Without Tracking: If you choose to mail your application, use a traceable shipping method. Losing your original documents in the mail can be a significant hassle.
- Applying for an ITIN When an SSN is Available: An ITIN cannot be issued if you are eligible for an SSN. You must apply for an SSN first in such cases.
By carefully reviewing the Form W-7 instructions and your supporting documents before submission, you can avoid these common errors and expedite your ITIN application.
What Happens After You Get Your ITIN?
Once your ITIN application is approved, you will receive an official notice from the IRS assigning you an ITIN. This notice is crucial for your tax records. Your ITIN is permanent and remains valid for the life of the taxpayer unless specific IRS actions are taken or the taxpayer is issued an SSN. However, ITINs that have not been used on a federal tax return for three consecutive tax years are subject to expiration by the IRS. If your ITIN has expired, you will need to renew it by submitting a Form W-7 and a valid tax return (or other supporting documentation for exceptions) during the renewal period.
Your ITIN serves several important functions:
- Filing U.S. Tax Returns: You must use your ITIN when filing your U.S. federal income tax returns (e.g., Form 1040-NR) and any other required IRS forms.
- Opening U.S. Bank Accounts: Many U.S. banks and financial institutions require an ITIN (or SSN) for non-residents to open a U.S. bank account. Having an ITIN can facilitate this process, allowing you to manage your finances in the U.S. more easily. Services like Mercury, Relay, or Brex often require an ITIN for non-resident founders to open business accounts. Learn more about opening a U.S. bank account at /bank-account.
- Establishing Credit: While not a direct credit-building tool, having an ITIN can be a step towards establishing financial ties in the U.S., which may indirectly help in building credit over time.
- Tax Compliance: It ensures you are compliant with U.S. tax laws for any income earned or business activities conducted in the United States.
ITIN Renewal: As mentioned, ITINs that are not used for three consecutive years expire. Additionally, the IRS has implemented a renewal program for ITINs that meet specific criteria. If your ITIN falls within certain ranges designated for renewal, you must renew it to continue using it for tax filing purposes. The IRS will typically send a notice (like CP-48) if your ITIN requires renewal. Renewal follows the same process as applying for a new ITIN: complete Form W-7, attach a U.S. federal tax return, and submit supporting documentation. The IRS provides specific guidance on which ITINs need renewal each year.
What if You Need an ITIN for a U.S. Business?
If your need for an ITIN stems from a U.S. business venture, such as owning a U.S. LLC, you will need to ensure all aspects of your business are compliant. This includes obtaining an Employer Identification Number (EIN) for your business if required, and filing annual reports like Form 5472 if you are a foreign-owned U.S. disregarded entity (like a single-member LLC). The process for obtaining an EIN is separate from an ITIN and is done using Form SS-4. You can find more information about EIN applications at /ein, and details on U.S. LLCs and their tax implications at /llc.
Seeking Assistance with Your ITIN Application
Navigating the U.S. tax system as a foreigner can be complex. Fortunately, there are resources available to help you understand and complete the ITIN application process. The primary avenues for assistance are:
- Certified Acceptance Agents (CAAs): As discussed, CAAs are authorized by the IRS to assist with ITIN applications. They can verify your original documents, reducing the need to mail them. Using a reputable CAA, such as those offered through /, can significantly simplify the process and provide a higher level of confidence in the accuracy of your submission.
- IRS Resources: The IRS website (irs.gov) provides comprehensive information, including instructions for Form W-7, FAQs, and updates on ITIN renewal. You can also contact the IRS directly by phone at 800-829-1040 for general inquiries.
- Tax Professionals: Experienced tax advisors, accountants, and enrolled agents who specialize in international taxation can provide personalized guidance. They can help you determine your eligibility, gather the correct documentation, and ensure your tax return is filed accurately alongside your Form W-7.
For individuals who are not U.S. residents or citizens, understanding how to get an ITIN number as a foreigner is a critical step towards meeting U.S. tax obligations and participating in the U.S. economy. By carefully following the application procedures and utilizing available resources, you can successfully obtain your ITIN.
If you have complex tax situations, are unsure about your filing requirements, or need assistance with U.S. business formation and tax compliance, consulting with a qualified tax professional or attorney is highly recommended.
