Deadline and where to file
Billerica values are set by the local board of assessors. File an abatement application with your local board of assessors by the due date of the first actual (not preliminary) tax payment for the fiscal year. In towns with quarterly billing that is usually February 1. If actual bills are mailed after December 31, it is May 1 or 30 days after mailing, whichever is later.
Reading this in fall 2026? For fiscal year 2027 (the July 2026 to June 2027 tax year, valued as of January 1, 2026), actual bills are usually mailed by December 31, 2026, and the abatement deadline is usually February 1, 2027. If your town mails bills after December 31, the deadline moves to May 1, 2027 or 30 days after mailing. Look at the due date of your first actual bill, because it is your deadline.
