What can change your bill?

The ACS effective rate is a ratio of medians, not a statutory rate. Local assessed values, levies, classification, caps and exemptions determine the actual bill.

Exemptions & assessment

No uniform flat exemption is applied. Enter your assessor-provided assessment ratio and qualifying exemption for a separate statutory scenario.

Payment dates & appeals

Municipalities bill and collect the tax. Hartford's first 2026 installment was due July 1 with an August 3 final payment date before delinquency; other municipalities and subsequent installments require their own bill.

Hartford's 2026 Board of Assessment Appeals filing deadline was February 20. Confirm your municipality's notice, any authorized extension and the deadline for the assessment year.

Check Connecticut’s official property-tax guidance

Use an assessed value, exemption, and local millage

This separate scenario needs your assessor’s inputs. An exemption applies only to eligible levies; do not apply it to the county’s historical effective rate.

1 mill = $1 per $1,000 of taxable assessed value.

Good questions. Clear answers.

How much is property tax on a $400,000 home in Connecticut?

The historical effective-rate estimate is $7,242 per year, or $604 a month. It multiplies $400,000 by 1.81%.

Is the effective rate the rate on my tax bill?

No. It is median real-estate taxes paid divided by median home value in the ACS 2020-2024 survey. Your taxing districts, assessed value, classification and exemptions determine your bill.

Can I subtract a homestead exemption from this estimate?

Use the separate statutory scenario with a qualifying levy. Subtracting an exemption from an ACS effective-rate estimate can double-count relief already reflected in taxes paid.

Does a higher purchase price change my assessment?

Assessment rules and reassessment dates vary by state and locality. Contact the linked official property-tax office before relying on a historical county ratio.

How do I appeal a property-tax assessment?

Read the deadline and procedure on your assessment notice, then use the official state guidance above to locate your assessor or review board. County survey data does not establish your appeal deadline.
