The following was compiled from a press release issued by the Town of Wilton. It was released on Feb. 20, 2026. *IMPORTANT: Deadline to appeal is Feb. 20, at 4:30 p.m.

Wilton, CT — Friday, Feb. 20, 2026: The Town of Wilton Assessor’s Office issued a press release today to clarify recent misinformation suggesting that the Town has undergone a town-wide real property revaluation for the upcoming 2025 Grand List.

Revaluation Timeline and Schedule

The Town of Wilton is not currently undergoing a town-wide revaluation. The Town completed its last revaluation for the Oct. 1, 2023, Grand List [released in 2024].

The state mandates that Connecticut towns must conduct a revaluation every five years. The last Wilton revaluation occurred in 2023 instead of 2022, as originally scheduled due to a postponement by one year. As a result, the next town-wide revaluation is scheduled for the Oct. 1, 2027, Grand List [to be released in 2028]. As that date approaches, the Town will provide comprehensive information, including direct mailers and public updates, to ensure all taxpayers remain informed. The state mandates physical revaluations every 10 years. The five years in between are updates.

Why Assessments Change Outside of a Revaluation Year

For property owners who have not performed new work on their homes recently, their assessments will remain at the 2023 level until the 2027 cycle begins. Outside of a revaluation year, an individual property assessment typically only changes if:

  • Physical work was performed: Determined by improvements tracked through the building permit process.
  • Discovery: New improvements or changes identified by the Assessor’s Office during field reviews.

In accordance with CT State statutes, assessment increase notices were mailed on Feb. 10, 2026, only to those property owners whose assessments changed due to the improvements or discoveries listed above.

Reviewing an Assessment

All current assessment information is available on the Town of Wilton’s website. Residents are encouraged to review their current data and compare it to prior years to determine if any changes have occurred. These records can be accessed online.

Board of Assessment Appeals — Deadline: Friday, Feb. 20

Residents who believe their current assessments — including any changes made due to improvements — do not accurately reflect the property’s value as of Oct. 1, 2023, have the right to appeal.

  • Deadline: Applications must be received by the Assessor’s Office no later than Friday, Feb. 20, at 4:30 p.m.
