IRS offices in Minnesota
The IRS operates Taxpayer Assistance Centers (TACs) for in-person tax services. Minnesota has 6 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 (no appointment needed)
- Prior-year returns — drop-off by appointment; TACs no longer prepare returns
⚠️ Most TAC services require an appointment — the IRS exceptions are making a non-cash payment, picking up blank forms and dropping off a current-year return. Call the local office below OR the IRS appointment line at 844-545-5640.
