Assessing Department
The Assessing Department is responsible for documenting and listing all taxable real property in Windham, maintaining accurate ownership data, and assisting with taxpayers to participate in the various programs offered per State law, such as veteran’s credits, elderly exemptions, etc.
The Assessing staff encourages taxpayers to contact us with questions or concerns and, in particular, to review the current assessment record card for correctness. Currently, property cards are available via a public computer in the Town Hall and online here. The CAI cards are updated on a monthly bases while our Vision cards are updated during our tax periods.
Windham's Assessing needs are currently contracted with MRI. Each MRI employee will be wearing an identification badge and driving either an MRI and/or Town of Windham marked vehicle. Windham Police also have vehicle makes, model and registration numbers, as well as the names and photos of each contractor. Do not hesitate to call Police 434-5577 or Assessing 434-7530 x3006 with concerns.
Primarily two (2) MRI staff members can be found sharing duties in the Assessing Department or conducting inspections around Town.
