How Taxes are Calculated: 

Tax bills are mailed out four times annually (in January, April, July and October), and they are due within 30 days of being sent. 

Tax rates in Massachusetts are determined by cities and towns. They are expressed in dollars per $1,000 of assessed value (often referred to as mill rates). For example, if your assessed value is $200,000 and your tax rate is 10, your total annual tax would be $2,000.

Why Do My Taxes Get Mailed to Boston?

The Town of Billerica uses Leader Bank located in the city of Boston. This process is able to handle thousands of payments per bill period and is generally processed as quickly as if you mailed your bills directly to Town Hall.
