Using the mill rate

Multiply your assessed value by the rate, then divide by 1,000. That's your tax before exemptions and credits.

Use the assessed value on your bill or the assessor's record. Connecticut assesses property at 70% of market value, so a $400,000 home is assessed at about $280,000.

How property tax works in Connecticut

Each town's assessor values property as of October 1 (the grand list). Assessments are 70% of market value, and towns revalue at least every five years. Once the town budget is adopted, the town sets its mill rate for the fiscal year that starts July 1.

Your bill is the assessed value times the mill rate, divided by 1,000, less any exemptions or credits. Fire, sewer and similar districts, where they exist, add their own rate.
