What to do before visiting an IRS office in New Hampshire

Start by calling the IRS appointment line. Tell the representative what you need help with and which office you want to use. Ask if the office can handle your issue, because some services are local and some are easier to finish online.

Bring photo ID, your taxpayer identification number, and the IRS letter or notice tied to the appointment. If you are going for identity verification, the IRS may ask for two forms of ID and a copy of the return for the year in question.

  • Call first. Use 844-545-5640 for TAC appointments.
  • Check the office page. Temporary closure notes and limited hours are shown on the individual office page.
  • Bring the notice. If the IRS mailed you a letter, bring the whole letter and any documents it asks for.
  • Use online tools when they fit. Transcripts, payments, refund status, and account details are often faster on IRS.gov.
