About IRS offices in Montana
The Internal Revenue Service operates 7 Taxpayer Assistance Centers in Montana to help residents with identity verification, ITIN applications, payments, transcripts and account questions. Centers are open Monday through Friday and see taxpayers by appointment only; many smaller ones close for lunch.
You can use any Montana IRS office regardless of your home address. Appointment lead times vary a lot between centers; if one is booked weeks out, ask for the next closest when you call 844-545-5640. Our "find office near me" tool sorts by proximity automatically.
Many transactions can be completed online at irs.gov without visiting an office — especially getting a tax transcript, requesting an IP PIN and setting up a payment plan. For appointments call 844-545-5640; for general tax questions the IRS individual line is 800-829-1040, both Monday through Friday, 7:00 AM to 7:00 PM local time. See our guide to reaching a live agent quickly.
