Equalization Bureau


What is it Equalization?

Equalization is a process carried out annually by municipalities and the New Hampshire Department of Revenue Administration (DRA) to ensure common property tax burdens are apportioned fairly and equitably among taxpayers. This is accomplished by conducting an annual ratio study using sales from a period of October 1 through September 30 of the following year. The information derived from the ratio studies is then used to calculate each municipality’s total assessed value used for county apportionment and the state education tax.

Reference Documents

The Equalization Manual provides an overview of the ratio study procedures and equalization process.

Reports

Each year the Equalization Bureau compiles information provided by municipalities on the MS-1, Summary Inventory of Valuation Report and statistics from the ratio study to equalize the value of each municipality for the equitable apportionment of taxes.
