An ITIN filer is any individual who submits an application to the Internal Revenue Service (IRS) for an Individual Taxpayer Identification Number (ITIN). You become an ITIN filer when you need this nine-digit number to meet U.S. tax obligations but do not have and are not eligible to obtain a Social Security number (SSN). The ITIN is specifically for federal tax purposes. It allows the IRS to track tax filings and payments made by individuals who are not U.S. citizens or permanent residents. Many non-residents and foreign nationals require an ITIN for various reasons, such as filing U.S. tax returns, claiming tax treaty benefits, or meeting certain U.S. business requirements. Understanding the process of being an ITIN filer is essential for compliance with U.S. tax law.
Who Needs to Be an ITIN Filer?
Individuals who are not U.S. citizens, not lawful permanent residents, and not eligible for an SSN must apply for an ITIN if they have a U.S. tax filing requirement or need to claim certain tax treaty benefits. This category includes, but is not limited to:
- Non-resident aliens who have U.S. source income and are required to file a U.S. tax return (e.g., Form 1040-NR).
- Resident aliens (as defined by U.S. tax law) who are not eligible for an SSN.
- Dependents or a spouse of a U.S. citizen or resident alien who require an ITIN for tax purposes.
- Individuals who need an ITIN to claim tax treaty benefits.
- Aliens who are required to file a U.S. tax return or information return, including those who are engaged in a trade or business in the United States.
Foreign nationals who are starting a U.S. business, such as forming a U.S. LLC, may also need an ITIN if they are required to file U.S. tax returns or information returns (like Form 5472 for certain LLCs with foreign owners) and do not have an SSN. Similarly, if you are an ITIN filer and plan to open a U.S. bank account, you might find that some U.S. banks require an ITIN in addition to your foreign passport. While many banks prefer an SSN, an ITIN can sometimes serve as a valid identification number for establishing financial relationships in the U.S.
The ITIN Application Process
The process for becoming an ITIN filer involves completing and submitting IRS Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires you to provide your full legal name, address, and foreign taxpayer identification number (if applicable). Crucially, you must also submit original or certified copies of documentation that proves your identity and foreign status. The IRS will not process your application without this supporting documentation.
There are three primary methods to submit your Form W-7 application:
- Mail 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 (if required) to the IRS address listed in the Form W-7 instructions. This is the most common method but often has the longest processing times.
- Apply Through a Certified Acceptance Agent (CAA): A CAA is an individual or entity authorized by the IRS to help taxpayers apply for an ITIN. CAAs can verify your original identity documents, preventing you from having to mail them to the IRS. This is a popular option as it allows you to keep your original documents and often results in faster processing. itin.net is an authorized Certified Acceptance Agent, assisting individuals in this process.
- Visit an IRS Taxpayer Assistance Center (TAC): Some IRS TACs offer ITIN application services by appointment. You will need to bring your original documentation to the appointment for verification. However, not all TACs provide this service, and appointments can be difficult to secure.
Regardless of the method chosen, the core requirement is the submission of Form W-7 and verifiable identification.
Required Documentation for ITIN Filers
To successfully file for an ITIN, you must provide documentation that proves both your identity and your foreign status. The IRS requires that you submit either original documents or certified copies of documents issued by the official agency that created them. Common documents accepted include:
- Passport: This is the most commonly used document as it proves both identity and nationality.
- National Identity Card: Must show your name, photograph, address, date of birth, and expiration date.
- U.S. Driver's License: Must show your name, photograph, date of birth, and issue/expiration dates.
- Birth Certificate: For individuals under 18, this can be used if it includes the necessary information. It must be accompanied by a photo ID if the birth certificate does not include a photo.
- Foreign Driver's License: Must show name, photograph, address, date of birth, and expiration date.
- Foreign Military Identification Card: Must show name, photograph, address, date of birth, and expiration date.
- Visa: For non-U.S. nationals, a visa can be used as a supporting document.
- National Identification Card: Issued by a country other than your country of citizenship (must show name, photograph, address, date of birth, and expiration date).
In addition to one primary identification document, you may need to submit a secondary document to verify your foreign status. For example, if your passport does not contain your full name or date of birth, you might need a birth certificate or national identity card to supplement it. The IRS provides a comprehensive list of acceptable documents in the instructions for Form W-7.
If you are applying for an ITIN for a dependent, the documentation requirements are slightly different. You will need to provide proof of your relationship to the dependent (e.g., birth certificate) and the dependent's identity and foreign status documents. For spouses, you'll need documentation proving the marriage.
Processing Times for ITIN Applications
Processing times for ITIN applications can vary significantly depending on the submission method and the IRS's current workload. When you file Form W-7 by mail directly to the IRS, it can take anywhere from 4 to 11 weeks to receive your ITIN. This timeline does not include the time it takes for your documents to be returned to you. If you are filing an income tax return along with your W-7, the IRS will process your tax return first, which can add to the overall time.
If you apply through a Certified Acceptance Agent, the process is generally faster. CAAs submit applications electronically or by mail, and the IRS typically issues ITINs through this channel within 7 to 10 weeks. The benefit of using a CAA is that they verify your documentation on the spot, and you do not have to mail your original or certified documents to the IRS, reducing the risk of loss or delay. The CAA then forwards the application to the IRS for final processing.
During peak tax seasons (typically January through April), processing times may be longer due to the high volume of applications the IRS receives. It is advisable to apply for your ITIN well in advance of any tax deadlines to avoid last-minute issues.
Common Mistakes Made by ITIN Filers
ITIN filers often encounter issues due to common mistakes made during the application process. Being aware of these pitfalls can help you avoid delays and ensure a smoother experience.
- Incomplete or Incorrect Form W-7: Failing to fill out all required fields on Form W-7, or providing inaccurate information, is a primary reason for application rejection. Ensure all personal details, addresses, and identification numbers are correct.
- Missing or Unacceptable Documentation: Not providing sufficient proof of identity and foreign status, or submitting documents that do not meet IRS requirements (e.g., photocopies instead of originals or certified copies), will lead to delays or rejection. Always refer to the official IRS instructions for a complete list of acceptable documents.
- Not Including a U.S. Tax Return (When Required): Many ITIN applications are tied to a requirement to file a U.S. tax return. If your situation necessitates filing a tax return (e.g., Form 1040-NR), you must submit it with your Form W-7. Applications submitted without a required tax return will be rejected.
- Using Expired Identification: Ensure all identification documents submitted are valid and have not expired. An expired passport or national ID card will not be accepted.
- Incorrectly Certified Documents: If you are not using a CAA and are mailing certified copies of documents, ensure they are properly certified by the issuing agency. Self-certified copies are not acceptable.
- Mailing Original Documents: While the IRS states they will return original documents, many applicants prefer to avoid this risk. Using a CAA or a TAC appointment allows you to have your documents verified without mailing them.
Carefully reviewing the Form W-7 instructions and double-checking all submitted materials before sending them can prevent these common errors.
ITIN Renewal and Expiration
Starting with the 2015 tax year, the IRS announced that ITINs that have not been used on a federal tax return for three consecutive tax years will begin to expire. Additionally, certain ITINs assigned before January 1, 2013, with middle digits between 70-82 (e.g., 9XX-70-XXXX) have expired. If your ITIN has expired, or if you anticipate needing to use it for a tax filing, you must renew it by submitting a new Form W-7 application along with updated identification documents.
Renewing an ITIN follows the same process as applying for a new one. You will need to complete Form W-7 again and provide current proof of identity and foreign status. You do not need to provide a tax return if you are only renewing your ITIN and do not have a current tax filing requirement tied to it. However, if you need the ITIN for an upcoming tax return, you will need to submit that return with your renewal application.
It is important to stay informed about your ITIN's status. The IRS provides a tool on its website to check if your ITIN has expired. If your ITIN has expired and you need it for tax purposes, you should apply for renewal as soon as possible to avoid any penalties or delays in filing your taxes. The renewal process also has the same processing times as a new application.
Getting Help with Your ITIN Application
Navigating the U.S. tax system can be complex, especially for individuals unfamiliar with its procedures. If you are an ITIN filer and feel uncertain about the application process, documentation requirements, or tax obligations, seeking professional assistance is highly recommended. The IRS offers resources, and there are also private services available.
Certified Acceptance Agents (CAAs) like those at itin.net are specifically trained to assist individuals with their ITIN applications. They can help ensure your Form W-7 is completed correctly, verify your original identification documents, and submit the application on your behalf. Using a CAA can significantly streamline the process and reduce the chances of errors.
For more complex tax situations, such as those involving international tax treaties, U.S. business structures (like U.S. LLCs), or significant U.S. income, consulting with a qualified tax professional or an Enrolled Agent (EA) who specializes in international taxation is advisable. They can provide personalized advice based on your specific circumstances and ensure compliance with all relevant tax laws. For questions regarding the application for an Employer Identification Number (EIN) for a U.S. business, a tax professional can also be invaluable.
