TAX COLLECTOR - Vehicle Registration Information

Per State of NH RSA 261:148:IV, you must have your registration in order to renew your vehicle registration (the State does not allow you to submit a photocopy). As a courtesy, the State will allow you to present your renewal notice instead of your registration.

PROOF OF RESIDENCY FOR NEW RESIDENTS

Proof of residency is required by the City of Portsmouth and the State of New Hampshire for new residents to register vehicles. We will accept one of the following documents, as long as it is dated within the past 30 days:

  • Utility Bill
  • Cable Bill
  • Pay Stub
  • Lease Agreement (notarized signatures of tenant and landlord or notarized letter required)
  • Envelope with postal forwarded address

For those residents who are NEW to the State of New Hampshire, you will be required to sign a City of Portsmouth "Residency Affidavit" which will be provided to you by the Tax Office at City Hall.

The State relies on the towns and cities to enforce residency; a resident is someone who has, through all of his actions, demonstrated a current intent to designate that place of abode as his principal place of physical presence for the indefinite future to the exclusion of all others (State of NH RSA 21:6). If the City has concerns about your residency, you may not be permitted to register.

In addition to Proof of Residency, the information below is required if you are a new resident in New Hampshire and have a vehicle currently registered out of state:"

  • Title of vehicle
