You register for an Individual Taxpayer Identification Number (ITIN) by completing and submitting IRS Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires supporting documentation to verify your identity and foreign status. The process can be completed by mailing your application and original or certified copies of your identification documents directly to the IRS, or by applying through an IRS-authorized Certified Acceptance Agent (CAA).
Eligibility for an ITIN
An ITIN is a tax processing number issued by the Internal Revenue Service (IRS) to individuals who are not eligible for a Social Security Number (SSN) but need a U.S. taxpayer identification number. You must have a U.S. tax filing or return requirement to be eligible. This typically includes:
- Non-resident aliens filing a U.S. federal income tax return (e.g., Form 1040-NR).
- U.S. resident aliens (based on days present in the U.S.) who are not eligible for an SSN and are required to file a U.S. tax return or are claimed as a dependent or spouse on a U.S. tax return.
- Dependents or spouses of U.S. citizens or resident aliens who do not have and are not eligible to obtain an SSN.
- Individuals who are nevertheless required to have a U.S. taxpayer identification number for U.S. tax purposes, such as certain individuals who are required to file Form 5472, Information Return of a 24% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business, when operating a U.S. LLC.
There are specific circumstances where an ITIN is needed even if you are not actively filing a tax return, such as for claiming tax treaty benefits or for certain banking or business purposes. However, the primary purpose of an ITIN is for tax administration. If you are planning to start a business, you will likely need an EIN in addition to an ITIN. You can apply for an EIN using Form SS-4.
Required Documentation for ITIN Application
To apply for an ITIN, you must provide original documents or certified copies of documents that prove your identity and foreign status. The IRS requires one original document that shows your name, photograph, and either your current U.S. address or foreign address. Additionally, you must provide a second document that shows your name and the date of your foreign status.
Commonly accepted documents include:
- Passport: This is the most preferred document as it establishes both identity and foreign status.
- National identity card: Must show name, photograph, date of birth, nationality, and have an expiration date.
- U.S. driver's license.
- Foreign driver's license.
- U.S. state identification card.
- Foreign military identification card.
- Foreign voters' registration card.
- Civilan મારાjage certificate (for dependents/spouses).
- Birth certificate (for dependents under 18).
- Medical records (dependents under 6).
- School records (dependents under 18).
If you cannot provide a passport, you will need to submit two alternative documents from the list above. One document must contain your photograph, and both must contain your name and the date of your foreign status. The IRS will not accept photocopies of documents unless they are certified copies from the issuing agency or a Certified Acceptance Agent (CAA).
How to Submit Your ITIN Application
There are three primary methods for submitting your ITIN application:
- Mail your application 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 applicable), to the Internal Revenue Service, Austin, TX 73301-0009.
- Apply through a Certified Acceptance Agent (CAA): This is often the simplest and most secure method. CAAs are individuals or entities authorized by the IRS to help taxpayers apply for ITINs. They can authenticate your original identification documents, meaning you can submit copies of your documents to the IRS without sending your originals. This avoids the risk of losing your vital documents during transit. The itin.net service is a CAA, offering a streamlined way to complete your ITIN application.
- Apply at an IRS Taxpayer Assistance Center (TAC): Some TACs offer ITIN application services by appointment. However, not all TACs provide this service, and you must verify availability and make an appointment in advance. You will need to bring your original identification documents to the TAC.
When applying via mail or TAC, you must submit original identification documents or certified copies from the issuing agency. CAAs, however, can certify your documents, meaning you do not have to mail your originals. This is a significant advantage of using a CAA.
The ITIN Application Process and Timeline
Once the IRS receives your completed Form W-7 and supporting documentation, the processing time can vary significantly. Generally, it takes the IRS 7 to 10 weeks to process an ITIN application submitted by mail during tax season, and 4 to 6 weeks during the off-season. However, these times can be longer during periods of high volume or due to IRS processing backlogs.
If you apply through a Certified Acceptance Agent (CAA), the process can be quicker. The CAA reviews your application and documents, and forwards them to the IRS. While the IRS still needs to approve the application, the CAA's involvement can sometimes expedite the initial review. The actual issuance of the ITIN by the IRS still follows their standard processing times. Some CAAs, like itin.net, can assist you with the entire process, making it more convenient.
After your application is approved, the IRS will mail you an ITIN assignment letter, typically Form CP-565, ITIN Assignment Letter. This letter contains your unique ITIN. It's crucial to keep this letter and your ITIN in a safe place, as you will need it for all future U.S. tax filings.
If you are applying because you need to file a tax return, and you are concerned about meeting tax deadlines, you may be eligible for an extension to file your return. The IRS grants automatic extensions, but you still need to file your return by the extended deadline. If your ITIN application is approved after you have filed your return without one, you may need to amend your return or wait for further instructions from the IRS.
Cost and Fees Associated with ITIN Registration
There is no fee to apply for an ITIN directly with the IRS. Whether you mail your application or visit an IRS Taxpayer Assistance Center, the application itself is free. The IRS does not charge for processing Form W-7.
However, if you choose to use a Certified Acceptance Agent (CAA), there may be a fee for their services. These fees are set by the CAA and cover the cost of their assistance in preparing and verifying your application and documents. The fees charged by CAAs can vary. Some CAAs may charge a flat fee, while others might have different pricing structures. The service provided by itin.net is a paid service designed to simplify the application process and ensure accuracy.
It's important to remember that the cost of using a CAA is for their service, not for the ITIN itself. If you are applying as part of a tax return filing, and you are using a tax preparer, they may also charge for their services. Ensure you understand all costs involved before proceeding.
Common Mistakes When Applying for an ITIN
Several common mistakes can lead to delays or rejections of your ITIN application. Understanding these pitfalls can help ensure a smoother process when you learn how to register for an ITIN number.
- Incomplete Application: Ensure all sections of Form W-7 are fully completed. Missing information or signatures will cause delays.
- Incorrect Documentation: Submitting the wrong type of identification documents or failing to provide all required documents is a frequent issue. Remember, you need documents that prove both identity and foreign status. If you don't submit a passport, you need two other documents, one with a photo.
- Not Sending Original or Certified Documents: If you are mailing your application directly to the IRS or applying through a TAC, you must send original documents or certified copies from the issuing agency. Photocopies are generally not accepted unless certified by the CAA.
- Forgetting the Tax Return: If your reason for needing an ITIN is to file a U.S. tax return, you must attach that return to your Form W-7 application. If you are applying for an exception category, ensure you select the correct one and provide the required documentation for that exception.
- Expired Identification: Ensure all identification documents submitted are valid and have not expired.
- Incorrect Address: Providing an incorrect mailing address can lead to the ITIN assignment letter being lost or returned to the IRS.
Carefully reviewing your application and all supporting documents before submission can prevent these common errors.
What Happens After You Receive Your ITIN?
Once you receive your ITIN assignment letter (Form CP-565) from the IRS, you can use it for all tax-related purposes. This includes filing your U.S. federal income tax return for the year in question and any subsequent years for which you have a filing requirement. If you obtained the ITIN to claim tax treaty benefits, you will use it when filing the relevant forms.
For individuals who formed a U.S. LLC, the ITIN is often used for tax filings such as Form 5472. If your LLC is a single-member LLC owned by a foreign individual, you will need an ITIN to file this form. Opening a U.S. bank account can also be facilitated with an ITIN, although some banks may have additional requirements. Some modern online banks like Mercury, Relay, or Brex may have specific requirements for non-residents opening accounts.
It's essential to keep your ITIN confidential and secure. Treat it like a Social Security Number. You will need to renew your ITIN periodically, as the IRS may require re-registration for certain ITINs.
ITIN Renewal and Updates
ITINs do not automatically expire, but the IRS may require holders to renew them. The IRS typically announces which ITINs need to be renewed. If your ITIN has not been used on a federal tax return for three consecutive tax years, it becomes invalid. Additionally, the IRS may require renewal of ITINs that have been issued before a certain date or have certain digits in the middle position (e.g., the 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, or 99 series).
If your ITIN needs renewal, you will follow a similar process to the initial application, completing Form W-7 again and providing updated identification documents. You do not need to resubmit original documents if you are using a Certified Acceptance Agent (CAA) who can verify them. The IRS will issue a new ITIN if your old one has expired and is no longer valid.
It is the taxpayer's responsibility to be aware of ITIN renewal requirements. Information regarding which ITINs need renewal is usually published on the IRS website and through tax professional channels. If you are unsure whether your ITIN needs renewal, it is best to consult with a tax professional or check the IRS website for the latest guidance.
