What this rate covers

  • Town government
  • Public schools
  • Fire, sewer and other special taxing districts in some towns levy their own rate on top, and aren't included here

Connecticut has no county government, so the town mill rate is the main rate on a Colchester bill.

Based on the October 1, 2025 grand list

Estimate your FY2027 bill

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.

Estimated annual tax before deductions

Deductions, credits and relief programs can lower your bill. This estimate doesn't include them.
