The data collection phase is underway for the October 1, 2025 Townwide revaluation. Over the next few months, eQuality Valuation Services will be mailing out Residential Data Mailers to all property owners in Town. By verifying your property data, data mailers help ensure that assessments are accurate and that the tax burden is distributed fairly among property owners.

Data Mailers are being sent in batches and were not sent out all at once. It may be possible someone you know across Town received their Data Mailer and you have not. All property owners will receive a Data Mailer, however not all at the same time.

Inspections

While completing the Data Mailer may reduce the necessity for an inspection to be completed, an inspection may still be required based on the changes noted on the mailer, when the property was last inspected, if the property was recently sold, if it has an open building permit, or by random selection for quality control purposes.

The security of our residents is a high priority. All Data Collectors will have a photo ID. Workers' car (model, registration, etc.) and photos will be registered with both the Police Department and Assessor's Office. Data Collectors are instructed not to enter any house unless an adult is present, and the adult has given permission to do an interior inspection. It is the prerogative of the taxpayer whether to allow a Data Collector to inspect the interior of their property.

Data Analysis and Valuation

While the data collection phase is being conducted, Appraisers will be studying property sales and determining where the actual increases and decreases in value are occurring. This study of property sales occurring over a 24-month period prior to October 1, 2025 allows for comparisons to be made and allows the Appraisers to establish parameters to estimate the value of properties that have not been sold. The Appraisers then review this collected data and apply the determining factors of the sales analysis to value each property.

Assessment Notices

Mid to late November assessment notices will be mailed out to all Town of Newington Real Estate property owners as part of the state-mandated revaluation for the October 1, 2025 assessment year.

Because of the increase in values, you may wonder what that means for your taxes that will be due next July 2026. The important thing to remember about taxes is that the assessment is only one part of the equation. An assessment is multiplied by the yearly mill rate to determine the taxes due. At this point, we do not know what the mill rate will be for the July 2026 taxes. The mill rate is determined as part of the Town’s budget process.

We caution taxpayers NOT to multiply the mill rate from last year to their new assessment because that will result in an inaccurate calculation. It is important to wait until the budget process in the Spring of 2026 when a new mill rate will be set by the Town Council (usually in May or June) to apply to the July 2026 tax bills.

Informal Hearings

Informal hearings are an opportunity for taxpayers to ask questions about the valuation of their property, explain why they believe the assigned value for their property is incorrect and review current property data. Informal hearings are held over the phone with a representative from eQuality valuation services. Each property that has an informal hearing will be reviewed on an individual basis to determine if a change in value is warranted.

Information on scheduling an informal hearing is located on your properties assessment notice. Scheduling your informal hearing can be done over the phone (860-827-3076) or online on the eQuality Valuation Services website.

Notification of informal hearing results will be mailed in January of 2026.

For more information on scheduling an informal hearing, please review the below document and video on the informal hearing process.

What to Know About Informal Hearings

Board of Assessment Appeals

The Board of Assessment Appeals is a formal appeal process for taxpayers who believe the assessment of their property is in excess of its fair market value. In order to appeal an assessment to the Board of Assessment Appeals, an appeal application must be completed and submitted to the Assessor's Office by February 20th, 2026. Once the applications are received, a hearing will be scheduled, and you will receive notice of the date and time of your hearing. The Board of Assessment Appeals will hold meetings to hear appeals in the month of March.

At your hearing you will have an opportunity to explain to the Board why you believe your assessment should be lower and present any information and evidence needed to support your appeal. After hearing the appeals, the Board will then review and make determinations on the disposition of the appeals. All appellants will then be notified of the Board of Assessment Appeal's decisions. If at that time an appellant still believes that their assessment is incorrect, they may appeal to the Superior Court within two months of the Board's action.

To file an appeal with the Board of Assessment Appeals, please complete the following application and submit to the Assessor's Office by Friday February 20, 2026.
