Property tax bills in Middlesex County are based on a home’s assessed value, which is compared with local tax rates set by municipalities and other taxing authorities. For a county with a median home price of $710,700, the final bill can vary widely depending on the neighborhood, local budgets, and any exemptions a homeowner may qualify for.

The county’s property tax burden is substantial: the 25th percentile tax bill is $5,028, while the 75th percentile is $10,614 and the 90th percentile reaches $15,086. That means many homeowners pay well above the national median property tax bill of $2,400. Bills can be especially high in places like Weston, where the median tax bill is $19,336, while Dracut has a much lower median tax bill of $4,858.
