IRS offices in Arizona

The IRS operates Taxpayer Assistance Centers (TACs) for in-person tax services. Arizona has 7 TACs.

TACs handle:

  • ITIN applications (Form W-7) — a TAC with ITIN services reviews your completed Form W-7, authenticates most supporting documents and mails your application package, all for free. A TAC is not a Certifying Acceptance Agent: the IRS lists CAAs as a separate, fee-based option
  • Identity verification for tax returns
  • Account problems and balance-due payments
  • Tax law questions (limited; most are routed to phone or IRS.gov)
  • Tax form pickup (walk-in for forms only)
  • Prior-year returns assistance

⚠️ All TAC visits require an appointment. Call the local office below OR the IRS appointment line at 844-545-5640.
