Somerville, MA Residential Exemption: Who Qualifies, Deadline

City-set rule

Somerville's Mayor and City Council decide each year whether to grant a residential exemption of up to 35% of the average assessed value of residential parcels, subtracted from the assessed value of owner-occupied homes. The city says the FY2027 amount is set at the end of December 2026.

Who qualifies

Own and occupy your Somerville home as your principal residence on January 1, 2026 (for FY2027). Proof of residency is required.

Deadline

April 1, 2027 (7:30 p.m.) for residential and statutory exemptions, per the city's Assessing calendar. Contact Assessing at (617) 625-6600 x3100.

Also offered

Statutory exemptions (seniors, veterans, blind owners and others) and a senior tax deferral, with the same April 1 deadline.
