Real Estate

*Please note that the Town Of Windsor Locks was part of a bill that postponed our Revaluation until 2024.

The property record reflects the market value as of the last real estate revaluation, October 1, 2024, the assessment is 70% of the value.

To calculate your Real Estate Tax bill -

To find your Appraised and Assessed values click the link above "EQUALITY ONLINE PROPERTY RECORD CARDS" and search your property address, scroll down to find the "Value Information" section and use the total value line.

Appraised Value of home X .70 = Assessed value

EX - 300,000 X .7 = 210,000

 

Assessed value X Mill Rate (ex. mill rate of 22.25 move decimal 3 places to left .02225 then multiply) = Taxes

210,000 X .02225 = $4,672.50

Property owners are encouraged to review property data. Contact the Assessor’s Office concerning value, exemption questions, and record discrepancies.

If this is the case the postmark from the post office (not a postage meter in your office) must state November 2, 2026 at the latest. These same rules apply for any exemption forms that would be filed.

*Please Note - CGS 12-42 States that "When the first day of November is a Saturday, or Sunday the declaration or extension request may be filed or postmarked the next business day following."

Motor Vehicles

Vehicles registered in Windsor Locks as of October 1st are assessed at 70% of the NADA New England Retail Value. The tax is distributed in July.
Vehicles registered in Windsor Locks after October 1st are assessed at 70% of the NADA New England Retail Value. The tax is distributed in January.

*PLEASE NOTE*

For the 2024 Grand List and moving forward the way that Motor Vehicles are valued will be changing.

The NADA New England Retail Value will no longer be used. The MSRP of the vehicle given by Price Digest multiplied by a depreciation percent established by the Connecticut Legislators for the year of your vehicle will give the value of the vehicle. That value is then multiplied by 70% to get the assessed value that you are taxed on.

Below is the depreciation amount per year that the legislation established.

EX.

2018 Model Year      MSRP = 20,000

20,000  X   .50  X  .70 = 7,000 Assessed

2005 Model Year      MSRP = 10,000

10,000  X  .15  X  .70 = 1,050 Assessed

1995 Model Year      MSRP = 3,000

3,000  X  .15  X  .70 = 315 Assessed ------ *500 Assessed

*The value of the vehicle that was over 20 years old was under the minimum of 500 so the value reverts to 500.*
