ITIN Application In Person: IRS TAC Offices 2026

How to Find Your Nearest IRS TAC Office

The IRS operates approximately 360 Taxpayer Assistance Centers across the United States. Not all locations accept ITIN applications, so you need to verify before visiting. Follow these steps to find and confirm a TAC that processes ITINs.

1. Visit the IRS TAC locator: Go to IRS.gov/help/contact-your-local-irs-office and enter your ZIP code. The tool shows the nearest TAC offices with addresses, phone numbers, and hours.
2. Call to confirm ITIN services: Call the TAC appointment line at 1-844-545-5640. Tell the representative you want to apply for an ITIN and confirm the TAC location you found accepts W-7 applications.
3. Schedule an appointment: TAC appointments are required for ITIN services. Walk-ins are generally not accepted. Book 2 to 3 weeks in advance, especially during tax season. The representative will provide available dates and times.

What to Bring to Your TAC Appointment

Come to your appointment with all required documents ready. If you arrive with missing items, the agent cannot process your application and you will need to reschedule.

• Completed Form W-7: Fill out the form before your appointment. Download it from IRS.gov. The TAC agent reviews but does not complete the form for you.
• Federal tax return: Your completed tax return (1040, 1040-NR, or other applicable form) must be attached to the W-7 unless an exception applies.
• Original identification documents: Bring your original passport (best option) or at least two documents from the 13 accepted documents list. Originals are required; the agent needs to examine them in person.
• Photo ID for building security: Most IRS buildings require a government-issued photo ID to enter. Passport, driver's license, or national ID card all work.
• Appointment confirmation: Bring the date, time, and reference number from when you scheduled the appointment.
• Supporting documentation: If applying under an exception (no tax return), bring the relevant supporting documents such as a letter from a bank, withholding statement, or other proof of your exception category.

What Happens During Your TAC Appointment

A typical ITIN appointment at a TAC follows this process and takes 30 to 60 minutes.

1. Check in at reception. Arrive 15 minutes early. Show your photo ID to security, then check in at the reception desk with your appointment details. You may wait 10 to 20 minutes before being called.
2. Meet with the TAC agent. The agent calls your name and brings you to a service window or private area. They review your Form W-7 for completeness and accuracy.
3. Document verification. The agent examines your original identification documents. They check for authenticity, verify your name and date of birth match the W-7, and confirm the documents are current and unexpired.
4. Tax return review. The agent confirms your tax return is attached to the W-7 (or verifies your exception documentation). They do not review the tax return for mathematical accuracy, only for attachment and completeness.
5. Application acceptance. If everything is in order, the agent accepts your application, makes copies of your documents for the IRS file, and returns all originals to you.
6. Processing begins. The TAC forwards your application to the Austin Processing Center. From this point, the standard 6 to 11 week processing timeline begins. The agent provides an estimated timeline and the phone number for status checks.

Advantages of Applying In Person at a TAC

The in-person application method offers several benefits over applying by mail.

• Same-day document return. You never give up your passport or other originals for weeks. The agent verifies and returns documents during the appointment.
• Immediate error detection. The TAC agent reviews your W-7 on the spot and can identify missing information, incorrect entries, or document issues before your application enters the processing queue.
• No mailing risk. You eliminate the risk of documents being lost in transit or at the IRS mailroom. Your application goes directly from the TAC into the system.
• Face-to-face questions. You can ask the agent questions about your application, document requirements, or the processing timeline. This is not possible with mail applications.
• Slightly faster total timeline. By eliminating mail transit time (3 to 14 days) and IRS intake processing (2 to 5 days), in-person applications save approximately 1 to 3 weeks compared to mail.

Limitations of In-Person ITIN Applications

While the in-person method has clear advantages, there are limitations to consider.

• US presence required. You must be physically in the United States to visit a TAC. This option is not available to international applicants who are outside the US.
• Limited TAC availability. Not all TAC offices accept ITIN applications. Rural areas may be hours from the nearest qualifying TAC.
• Appointment required. Walk-ins are not accepted for ITIN services. Appointments must be scheduled in advance and may be booked 2 to 3 weeks out during busy periods.
• Business hours only. TACs operate Monday through Friday, 8:30 AM to 4:30 PM. No weekend or evening hours are available.
• Processing time is not faster. The TAC sends your application to the Austin Processing Center where it joins the same queue as mail applications. The 6 to 11 week processing time is identical.
• No tax preparation help. The TAC agent reviews your W-7 and documents but does not help you prepare your tax return. You must arrive with a completed return.

How to Prepare for a Successful TAC Appointment

Maximize your chances of a successful appointment with these preparation steps.

1. Complete Form W-7 carefully at home. Review every field. Make sure your name matches your passport exactly. Sign and date the form. Use our W-7 form guide for line-by-line instructions.
2. Prepare your tax return in advance. The TAC does not prepare returns. Use tax software, a CPA, or a VITA site to complete your return before the appointment.
3. Bring more documents than required. If you have a passport plus a national ID card, bring both. Extra documents strengthen your application and give the agent options if one document has an issue.
4. Check document expiration dates. All documents must be current and unexpired on the day of your appointment. Renew anything that is close to expiring.
5. Arrive 15 minutes early. IRS buildings have security screening (similar to airports) that takes 5 to 10 minutes. Late arrivals may lose their appointment slot.
6. Bring a pen. You may need to make minor corrections or sign additional forms at the appointment.

What Happens After Your TAC Appointment

After the TAC accepts your application, the following timeline applies.

• Week 1 to 2: The TAC forwards your application to the Austin Processing Center. It is entered into the processing system.
• Weeks 2 to 12: Standard IRS processing (6 to 11 weeks depending on season). No updates are available during this period.
• After 7 weeks: Call 1-800-829-1040 for a status update. Have your name and the date of your TAC appointment ready.
• Week 8 to 13: CP565 notice mailed to your address with your assigned ITIN. Allow 1 to 2 weeks for delivery.
