About Massachusett's Ad Valorem Tax

Massachusetts property real estate taxes are calculated by multiplying the property's value by the location's ad valorem tax rate.

This is no different from most other New England states, like New Hampshire, Vermont, Maine, Connecticut, and Rhode Island.

Property tax rates are also referred to as property mill rates. If you're wondering what is the mill rate or what is the property tax rate in any town in Massachusetts, you've come to the right page.

Taxable property in Massachusetts is assigned by an assessor to one of four classes: commercial, industrial, open space, or residential. The tax bill for a property is based upon the fair market value of that asset.

Factors considered by assessors when calculating the value of a property include: the property's location, what it is currently used for, the lot size, as well as building size.

Exemptions for property tax exist for eligible senior citizens and veterans, religous and philanthropic institutions, and blind individuals. See the Massachusetts Department of Revenue website for additional information about qualifying property tax exemptions.

For more information about exemptions for seniors over 70, veterans, and legally blind persons, please contact your local assessors.
