The Assessor’s Office is responsible for administering Massachusetts property tax laws effectively and equitably and for producing accurate and fair assessments of all taxable property. Taxable property includes not only real estate but personal property, motor vehicle and boat excise as well. Another function of the office is to send exemption and deferral forms to property owners who have received an exemption/deferral during the previous year. The most common exemptions are elderly, blind and qualifying veterans.

The Chief Assessor and staff are available to answer your questions during regular office hours and will be happy to provide assistance in filling out forms.

You'll find meeting notices, agendas and meeting minutes on the Board of Assessor's page.

The City budget runs on a fiscal year basis, July 1 to June 30. Property owners receive two tax bills within the year, a PRELIMINARY tax bill and an ACTUAL tax bill. Each bill includes two quarterly payments. The PRELIMINARY tax bill includes quarterly payments due on August 1 and November 1, your first and second quarter payments. The ACTUAL tax bill includes quarterly payments due on February 1 and May 1, quarters three and four.

The PRELIMINARY tax bill is also referred to as an estimated tax bill. The bill is based on the previous (calendar) year assessment of your property and the previous year’s tax rate.

The City budget is set for July 1st (that’s what your bills pay for), and the current calendar year property values are certified by the state in the fall, followed by a new tax rate set by the end of the year.

Then, the ACTUAL tax bill can be issued for the remaining balance of what is owed.

Here’s an example:
In FY23 your preliminary tax bill was for $3,974.95 (or $1987.47 and $1987.48 for each quarter). This was based on a 2021 calendar year value of $449,400 and a tax rate of $17.69 to generate a bill for just half the year.

                449,400 / 1,000 = 449.4 x 17.69 = 7,949.88 / 2 = 3,974.95 / 2 = 1987.47

Once the budget, property values, and rates were set it was determined that your property value was now $498,100 and the tax rate is now $16.34. You should pay a total for the year of $8,138.95.

                498,100 / 1,000 = 498.1 x 16.34 = 8,138.95

 You’ve already paid $3,974.95. So, you owe $4,164.

 Your ACTUAL tax bill will be for a total of $4,164 with two quarterly amounts due of $2,082.

 In this scenario your bill for the year has increased $189.06 from last year to this year. 

Massachusetts law requires that all municipalities establish the full and fair cash value of all real estate as of January 1st of the prior year.  It is the responsibility of the Assessor's Office to establish the taxable valuation of each individual piece of property in the City. However, the Assessors do not create value. Buyers and sellers create the value via their transactions in the marketplace.
