IRS Taxpayer Assistance Centers (TACs) offer in-person help for tax issues that cannot be resolved online or by phone. Before visiting, make an appointment, confirm that your local office handles your issue, and bring two forms of identification, your SSN or ITIN, and the relevant tax records. Services and hours vary by location.
What help can you get at an IRS Taxpayer Assistance Center?
A TAC is for issues that need in-person assistance, such as identity authentication or reviewing documents. Not every office provides every service, so check the IRS Taxpayer Assistance Center locator for the location’s services and hours, then confirm before traveling.
Selected TACs also help with ITIN applications. Staff can review a completed Form W-7, authenticate most supporting documents, return authenticated documents after the appointment, and mail the application package for processing. An applying spouse or dependent must attend in person with their own application package. Designated offices can review original documents and certified copies from issuing agencies. Check the location’s ITIN availability and appointment instructions before you go. The IRS offers phone interpretation in many languages; sign-language interpreter arrangements use TTY/TDD.

What should you bring to your appointment?
- Two forms of identification: Bring a current government-issued photo ID and a second identity document. Examples on the IRS appointment page include a driver’s license, state ID, passport, Social Security card, lease, mortgage statement, vehicle title, utility bill, voter registration card, birth certificate, or qualifying school records. Some documents have qualifications; follow the instructions for your appointment.
- Your SSN or ITIN: Have your Social Security number or Individual Taxpayer Identification Number available.
- Documents for the issue: Bring the IRS notice or letter, the relevant tax return, and supporting records for the tax year or account question. Include any specific documents requested in your appointment confirmation or notice.
- ITIN application materials, if applicable: For an ITIN appointment, bring the completed Form W-7 and the required supporting documents, following the selected office’s instructions.
Keep the letter and supporting records together so you can locate the documents the IRS asks to see. Do not assume a generic checklist overrides a notice’s specific requirements.

How to arrange and prepare for a TAC visit
- Find an office: Use the IRS locator to check the nearest TAC’s hours and services.
- Call to schedule: Appointments are required. Scheduling helps confirm the office can provide the service you need; the IRS appointment page also describes optional text reminders.
- Review your appointment instructions: Match your documents to the issue and follow any location-specific entry directions.
- Arrive on time: The IRS says an appointment may be canceled if you arrive more than 15 minutes late without checking in. The IRS page says not to bring food or drinks, cameras, or weapons.
The IRS’s 2026 Publication 15-A says, “All TACs now provide service by appointment,” describing this as a way to know in advance that the needed service is available without long waits. Check current local instructions for your particular office and visit.

Can you resolve the issue without visiting?
For routine account tasks, try the IRS’s online and phone help options first. The IRS lists online services for making payments, setting up payment plans, getting transcripts, checking refunds, viewing account information, filing online, and finding tax answers. A TAC is appropriate when remote options do not resolve the issue or the matter requires in-person help.
If an IRS problem is causing economic hardship or remains unresolved through ordinary channels, the Taxpayer Advocate Service may be another route. It is distinct from a TAC appointment and is intended for certain serious problems or hardship cases.
