You can obtain an ITIN by completing and submitting Form W-7, Application for IRS Individual Taxpayer Identification Number, along with original or certified copies of identification documents and a supporting U.S. federal income tax return. The process is designed for individuals who need a U.S. taxpayer identification number but do not have, and are not eligible to obtain, a Social Security number (SSN).
This guide details how to get an ITIN, covering eligibility, required documentation, submission methods, and common pitfalls. Understanding the ITIN application process is the first step for many foreign nationals looking to engage with the U.S. tax system, whether for personal tax obligations, investment purposes, or business setup. The question of "itin numarası nasıl alınır" (how to get an ITIN number) is a common one for those new to these requirements.
Eligibility for an ITIN
An ITIN is issued by the Internal Revenue Service (IRS) to individuals who are required to have a U.S. taxpayer identification number for tax purposes but do not have an SSN. This primarily includes:
- Non-resident aliens filing a U.S. tax return.
- Resident aliens (based on days present in the U.S.) filing a U.S. tax return, who are not eligible for an SSN.
- Dependents or spouses of U.S. citizens or resident aliens who are non-resident aliens and require a U.S. taxpayer identification number.
- Dependents or spouses of U.S. citizens or resident aliens who are resident aliens but not eligible for an SSN.
- Individuals (including U.S. citizens) filing a U.S. tax return who are foreign nationals and not eligible for an SSN (e.g., some students, researchers, or individuals with specific visa statuses).
- Individuals who have a U.S. tax obligation but are not eligible for an SSN, such as those filing specific informational returns.
Crucially, you must have a valid reason for needing an ITIN, which is typically demonstrated by filing a U.S. federal income tax return. Exceptions exist for certain situations where an ITIN is required even without filing a tax return, such as for withholding on U.S. source income under a tax treaty, or for specific reporting requirements related to U.S. business activities like those of a U.S. LLC owner filing Form 5472.
Required Documents for ITIN Application
The core of your ITIN application is Form W-7. This application must be submitted with several supporting documents:
Proof of Identity and Foreign Status: You must provide original or certified copies of identification documents that prove both your identity and your foreign status. The most commonly accepted documents are:
- Passport: This is the preferred document as it establishes both identity and foreign status. If your passport is expired, it can still be used if it was valid when issued and within 5 years of the expiration date.
- National Identity Card: Must contain your photograph, name, address, date of birth, and expiration date.
- U.S. Driver's License: Must contain your photograph, name, address, date of birth, and expiration date.
- Birth Certificate: Must include your name, date of birth, place of birth, and parents' names. If the birth certificate is not in English, a certified translation must accompany it.
- Foreign Driver's License: Must contain your photograph, name, address, date of birth, and expiration date.
- Foreign Military Identification Card: Must contain your photograph, name, address, date of birth, and expiration date.
- Visa: Must be valid and show your name and expiration date.
- National Identity Card (Country of Origin): Must show your photograph, name, address, date of birth, and expiration date.
- Civilian Foreign Identification Card: Must show your photograph, name, address, date of birth, and expiration date.
- Voter Registration Card (Country of Origin): Must show your photograph, name, address, date of birth, and expiration date.
- Medical/Health Records (from a foreign country): Must show your name, address, date of birth, and use of your name within the last 5 years.
- School Records (from a foreign country): Must show your name, date of birth, and attendance within the last 5 years.
You must submit one of these documents that shows your photograph, name, date of birth, and expiration date. If the document does not contain all required information, you may need to submit additional documents to meet the requirements.
Original or Certified Copy of a U.S. Federal Income Tax Return: Unless you qualify for an exception, you must submit a U.S. federal income tax return with your Form W-7. If you are applying for an ITIN because you are required to file a tax return and are claiming treaty benefits, you will need to attach the relevant tax forms (like Form 1040-NR for non-residents) and any required schedules or statements. If you are claiming an exception, you will need to provide documentation supporting that exception. For example, if you need an ITIN to open a U.S. bank account as a non-resident, you may be able to apply without a tax return, but you will need to provide documentation from the financial institution (like a letter from Mercury, Relay, or Brex). If you are an owner of a U.S. LLC and need an ITIN to file Form 5472, you will submit that form with your Form W-7.
- Certified Copies: These are copies authenticated by the issuing agency (e.g., the passport office, the U.S. embassy or consulate, or the IRS Acceptance Agent). A photocopy of a document will generally NOT be accepted unless it is certified by the issuing agency.
Documentation for Exceptions (if applicable): If you are applying for an ITIN without filing a tax return, you must provide specific documentation. These exceptions include:
- Withholding on U.S. income under tax treaty provisions.
- Taxpayer who is a non-resident alien with income effectively connected with a U.S. trade or business.
- Taxpayer who is a non-resident alien spouse filing a U.S. tax return.
- Dependent or spouse of U.S. citizen/resident alien filing a U.S. tax return.
- Non-resident alien who is a partner in a U.S. partnership.
- Taxpayer who is a non-resident alien filing a U.S. tax return to claim treaty benefits.
- Taxpayer who is a non-resident alien filing a U.S. tax return to claim an exception under Section 6013(g) or 6013(h).
- Individuals who need an ITIN to meet specific IRS requirements, such as opening a U.S. bank account.
How to Submit Your ITIN Application
You have three primary methods for submitting your Form W-7 application:
By Mail to the IRS: You can mail your completed Form W-7, supporting identification documents, and your tax return (if applicable) directly to the IRS ITIN Operation at the address specified in the Form W-7 instructions. This is the most common method for those who do not wish to use an Acceptance Agent. The IRS will review your application and supporting documents. If approved, they will issue your ITIN and return your original identification documents, typically within 7 to 11 weeks, though processing times can vary significantly.
Through a Certified Acceptance Agent (CAA): This is often the most convenient method. A Certified Acceptance Agent (CAA) is an individual or entity authorized by the IRS to help taxpayers apply for ITINs. CAAs can authenticate your original identification documents and forward your Form W-7 application to the IRS on your behalf. A significant advantage of using a CAA is that you usually do not have to mail your original documents to the IRS; the CAA will return them to you directly after verifying them. This significantly reduces the risk of losing your important identification papers. The itin.net service is a Certified Acceptance Agent program, providing assistance with this process.
At an IRS Taxpayer Assistance Center (TAC): Some IRS Taxpayer Assistance Centers offer ITIN application services by appointment. You must bring your original documentation or certified copies to the TAC. However, not all TACs provide this service, and appointments can be difficult to secure. You should verify with your local TAC if they offer ITIN application processing before visiting.
Processing Times and Costs
Cost: There is no fee charged by the IRS to apply for an ITIN. However, if you use a Certified Acceptance Agent (CAA) like itin.net, they may charge a service fee for their assistance. If you mail your application directly to the IRS or visit a TAC, the application is free.
Processing Time: The IRS processes ITIN applications on a first-in, first-out basis. Standard processing times can range from 7 to 11 weeks from the date the IRS receives your application. However, these times can fluctuate based on the volume of applications received, especially during peak tax seasons (January through April). It is advisable to apply well in advance of any tax filing deadlines.
- Peak Season (Jan-Apr): Expect longer processing times, potentially up to 11 weeks or more.
- Off-Peak Season (May-Dec): Processing times may be closer to the standard 7 weeks, but this is not guaranteed.
If your application is incomplete or missing required documentation, the IRS will notify you, which will further delay the process. If your application is rejected, you will receive a notice explaining the reason, and you will need to correct the issues and reapply.
Common Mistakes to Avoid
Several common errors can lead to delays or rejections of your ITIN application. Being aware of these pitfalls can save you time and frustration:
- Incomplete Form W-7: Ensure all sections of the Form W-7 are filled out accurately and completely. Missing information is a primary reason for delays.
- Incorrect or Missing Identification Documents: Failing to provide original or certified copies of acceptable identification documents, or providing documents that do not meet the IRS criteria, will result in rejection. Remember that the document must prove both identity and foreign status.
- Not Submitting a Tax Return (When Required): If you do not qualify for an exception, failing to include a complete and accurate U.S. federal income tax return with your Form W-7 is a common mistake.
- Expired Identification: Using expired identification documents (unless it's a passport that falls within the IRS grace period) will lead to rejection.
- Incorrect Mailing Address: If mailing your application, ensure you use the correct, current IRS address for ITIN applications, as listed in the Form W-7 instructions.
- Not Signing Form W-7: The application must be signed and dated by the applicant.
- Submitting Photocopies Instead of Originals/Certified Copies: Unless specifically allowed, photocopies of identity documents are not accepted.
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 9-digit ITIN. Keep this letter in a safe place, as you will need it for all future interactions with the IRS. Your ITIN is permanent and does not expire, even if you renew your visa or change immigration status.
However, some ITINs assigned before December 2012 may need to be renewed if they have not been used on a federal tax return in the last three consecutive tax years. The IRS began a renewal program for these older ITINs. If your ITIN falls into this category, you will receive a notice from the IRS, typically Notice CP-48, before needing to renew. The renewal process generally involves submitting a Form W-7R and updated identification documents.
Your ITIN is essential for various tax-related activities:
- Filing your U.S. federal income tax returns.
- Claiming tax benefits and deductions.
- Opening a U.S. bank account (though not always required, it's often a step for non-residents).
- Establishing credit or obtaining loans in the U.S.
- Complying with U.S. tax laws if you own a U.S. LLC (which requires filing Form 5472 if you are a foreign owner).
- Obtaining an Employer Identification Number (EIN) or Form SS-4 if you plan to start a business.
When to Seek Professional Help
While the ITIN application process is straightforward for many, complex situations may require professional assistance. Consider seeking help from a tax professional or a Certified Acceptance Agent (CAA) if:
- You are unsure about your eligibility or the specific documentation required.
- You need to file complex tax returns, such as those involving foreign income, investments, or U.S. business activities.
- You are applying for an ITIN for multiple family members.
- You prefer not to mail your original identification documents to the IRS.
Professionals can guide you through the entire process, ensure your application is complete and accurate, and help avoid common mistakes. For those looking to establish a U.S. business presence, obtaining an ITIN is often the first step, followed by securing an EIN and potentially forming a U.S. LLC. Services like itin.net and its partners can assist with these subsequent steps as well, providing a comprehensive solution for non-residents engaging with the U.S. financial and tax systems.
