The North Slope Borough does not have property data and/or tax information online at this time.

The mission of the Assessing Division is to perform all statutory requirements in administering the taxation of real and personal property located with the NSB. The division values real and personal property and responds to value appeals.

The division maintains all records necessary to establish ownership of taxable real property such as maps, title documents, deeds, and other records of all Borough real property transactions. Annual physical inspections are performed on all real properties. The division has assumed responsibility for the valuation of most oil and gas property located in the borough. The division also reviews the state’s evaluation of oil and gas properties located in the Borough to protect the NSB tax base and maximize revenues.
