How it works
In Boston, property is assessed at full and fair cash value as of January 1 each fiscal year. Property tax is calculated on this assessed value. The City sets separate tax rates for residential, commercial, industrial, and personal property classes. This calculator estimates residential property tax by multiplying the assessed value by the published Boston residential rate.
Examples
For example, using the residential rate of 0.0109 per $1 of assessed value (equal to $10.90 per $1,000), a home assessed at 600,000 would produce an estimated residential property tax of 6,540 before exemptions.
Limitations and important notes
Boston provides a residential exemption for eligible owner-occupied primary residences, which reduces taxable value for qualifying parcels. Additional exemptions may apply based on eligibility. Because exemptions depend on owner status and other criteria, this tool does not automatically apply them. This calculator estimates property tax using assessed value and the residential rate only and does not replicate an official tax bill.
