The Massachusetts Interactive Property Map, developed by MassGIS, enables developers, banks, realtors, businesses, and homeowners to view seamless property and tax information across the Commonwealth.
One of a handful of such state-sponsored tools in the country, the ongoing effort is the product of MassGIS working with community assessors, their mapping consultants, and other stakeholders. 1
For help using the interactive map, see the User's Guide.
The assessment data are also available in accessible format in the Property Information Finder, which meets 508 Compliance Requirements and allows you to search for property assessment data by address only. It does not include a map or the other features provided by the Interactive Property Map.

MassGIS attempts to display annual updates of property information for each community. This, however, requires all communities to maintain and submit standardized assessor maps and assessor information. Until this effort is fully implemented, some of the assessor data may not be entirely current. The fiscal year of the information is displayed in a pop-up when you click a particular parcel.
The most up-to-date assessing information is available directly from each municipality, typically through the assessing department. Many municipal web sites have an online property lookup feature, usually on the assessor's page.
The Massachusetts Property Information viewer displays property boundaries from assessor parcel maps for all communities in the Commonwealth. Each parcel is linked to selected descriptive information from the assessor database.
Assessor’s parcel mapping is a representation of property boundaries, not an authoritative source.
