The IRS processing center where you mail your Form W-7, Application for IRS Individual Taxpayer Identification Number, depends on whether you are applying from within the United States or from overseas, and whether you are filing with a U.S. federal income tax return.
Mailing Your ITIN Application: The Direct IRS Address
If you are mailing your Form W-7 directly to the IRS without filing a U.S. tax return at the same time, you will mail it to the Austin, Texas, address. This is the primary mail destination for ITIN applications that are not attached to an income tax return. For most applicants, this is the simplest method if they are not yet ready to file their tax return.
Internal Revenue Service Austin, TX 73301-0009
This address is for applications where you are requesting an ITIN solely for purposes other than filing a U.S. federal income tax return. Examples include requirements for withholding and reporting on U.S. source income, or for certain U.S. business activities. You must include original or certified copies of your identification documents and proof of foreign status with your application.
Mailing Your ITIN Application with a Tax Return
If you are filing your U.S. federal income tax return (such as Form 1040-NR, U.S. Nonresident Alien Income Tax Return) concurrently with your Form W-7 application, you will mail both forms together to the same IRS service center that handles tax returns for the region where you reside, or the specific service center designated for your tax filing.
However, the most common practice for individuals filing a return and applying for an ITIN simultaneously is to mail both forms to the Austin, Texas address as well. This consolidates the processing. The IRS will then process your tax return and your ITIN application together.

When mailing your tax return and W-7 together, ensure all required documentation for the W-7 is included. This includes your original or certified copies of identification documents and proof of foreign status. The IRS will issue your ITIN and then process your tax return using that number.
Using a Certified Acceptance Agent (CAA) to Avoid Mailing
Many applicants choose to use a Certified Acceptance Agent (CAA) to avoid mailing original identification documents directly to the IRS. A CAA is an individual or entity authorized by the IRS to help taxpayers apply for ITINs. When you apply through a CAA, you present your original identification documents to the CAA, who then verifies them and forwards your completed Form W-7 application, along with copies of your documentation, to the IRS on your behalf.
This method is often preferred because you do not have to mail your original passport or other vital identification documents, which can take weeks or months to return. The CAA handles the submission process for you. This is a key benefit of using services like itin.net, which can connect you with authorized CAAs.
CAAs can also assist with the application process itself, ensuring that your Form W-7 is correctly completed and that you have all the necessary supporting documents. This can significantly reduce the chances of your application being delayed or rejected due to errors. The CAA will submit the application to the appropriate IRS ITIN Operation office, typically in Austin, Texas, but you do not mail it yourself.
What Documents Must Be Mailed with Form W-7?
Regardless of where you mail your Form W-7, you must include specific documentation to prove your identity and foreign status. The IRS requires either original identification documents or certified copies of those documents from the issuing agency (like the U.S. State Department for passports).
Acceptable identification documents typically include:
- U.S. Passport: An original or certified copy.
- National Identity Card: Must show name, photograph, address, date of birth, and expiration date. It must be current.
- U.S. Driver's License: Must show name, photograph, date of birth, current address, and expiration date. It must be current.
- Foreign Driver's License: Must show name, photograph, date of birth, address, and expiration date. It must be current.
- Foreign Birth Certificate: Must show name, date of birth, and place of birth. It must be current.
- Civil Birth Certificate: Must show name, date of birth, and place of birth. It must be current.
- Voter Registration Card: Must show name, photograph, date of birth, and current address. It must be current.
- Medical Records: For individuals under 18, a medical record can be used if it shows name and U.S. address.
- School Records: For individuals under 18, a school record can be used if it shows name and U.S. address.
You must also provide proof of foreign status. This is usually demonstrated by your passport or other documents that show you are not a U.S. citizen. If you are applying based on being a dependent or a spouse of a U.S. citizen or resident alien, additional documentation may be required, such as a birth certificate or marriage certificate.
If you choose to mail original documents, the IRS will return them by mail, typically within 60 days. However, this can take longer during peak processing periods.
Processing Times for Mailed ITIN Applications
Once your Form W-7 application is mailed to the IRS, the processing time can vary significantly. The IRS generally states that it can take up to 11 weeks for an ITIN to be assigned, especially if you are applying during the tax season (January through April). Applications received outside of this period may be processed faster, sometimes within 6 to 8 weeks.
However, these are estimates, and actual processing times can be longer due to high volumes, incomplete applications, or the need for additional verification. If your application is incomplete or missing required documentation, the IRS will send you a notice, which will further delay the process. You will receive a Form CP-565, Notice of ITIN Assignment, once your ITIN has been issued.
If you are mailing your application with a tax return, the processing time for both will be extended. The IRS will assign your ITIN and then process your tax return. This combined process can take longer than an ITIN-only application.
What If My Application is Rejected?
If your Form W-7 application is rejected, the IRS will send you a notice explaining the reason for the rejection. Common reasons for rejection include:
- Missing or incomplete identification documents.
- Failure to provide proof of foreign status.
- Incorrectly completed Form W-7.
- Application not signed or dated.
- Failure to include a valid U.S. federal income tax return (if filing concurrently).
- Documents not being original or certified copies from the issuing agency.
If your application is rejected, you will need to correct the errors and resubmit the application. You will need to determine the correct IRS address for your resubmission, which will likely be the same Austin, Texas address unless your circumstances have changed significantly or you are now filing with a tax return. Reviewing the rejection notice carefully is essential to understand what needs to be fixed. You may want to seek assistance from a Certified Acceptance Agent or a tax professional to ensure the resubmission is correct.
Key Considerations for International Applicants
When considering where to mail your ITIN application, remember that international applicants have specific needs. The IRS understands that obtaining original identification documents and mailing them internationally can be challenging. This is why the Certified Acceptance Agent program is so valuable for non-residents.
If you are applying for an ITIN because you have U.S. source income that requires reporting or withholding, or if you are establishing a U.S. business, such as a U.S. LLC, you will need an ITIN. The process of forming a U.S. LLC and obtaining an EIN (Employer Identification Number) often precedes or runs parallel to the ITIN application. For instance, if you are forming a U.S. LLC, you will likely need an EIN first, which is obtained by filing Form SS-4 with the IRS. This often requires a U.S. address or a foreign address. After forming the LLC and potentially obtaining an EIN, you might then need an ITIN for yourself or other members to comply with IRS reporting requirements, such as filing Form 5472 for foreign-owned U.S. disregarded entities. Establishing a U.S. bank account is another common step for those setting up a U.S. business, and an ITIN or EIN is often required for this as well.
International applicants should also be aware of the potential for delays in receiving mail internationally. This is another reason why using a CAA can be advantageous, as they are accustomed to the process and can often provide more immediate feedback on the completeness of your application.
When to Seek Professional Help
While the Form W-7 application process is designed to be manageable, many complexities can arise, especially for non-residents. Seeking professional help can save time and prevent costly errors. Consider consulting a tax professional or a Certified Acceptance Agent (CAA) if:
- You are unsure about which supporting documents to submit.
- You have complex income sources or tax situations.
- You need to file a U.S. tax return concurrently and are unfamiliar with U.S. tax forms.
- You are concerned about mailing original identification documents.
- Your ITIN application has been rejected previously.
Professionals can guide you through the entire process, from selecting the correct documents to ensuring your Form W-7 is filled out accurately. Using a service like itin.net can help you find qualified CAAs who can assist you in person, thereby avoiding the need to mail sensitive documents. This is particularly helpful if you are considering establishing a U.S. business, which may also require obtaining an EIN or forming a U.S. LLC. These professionals can also advise on related matters such as opening a U.S. bank account.
Remember, the IRS requires specific documentation and adherence to procedures. Ensuring your application is correct from the start is the most efficient way to obtain your ITIN. The question of where to mail itin application is just one part of a larger process for many foreign nationals engaging with the U.S. tax system.
