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 their questions or concerns and, in particular, to review their current assessment record card for correctness. Currently, property cards are available via a public computer in the Town Hall and online here.
Windham completed an assessment revaluation in 2010. The purpose of the revaluation was to correct errors, add property improvements, and adjust values to reflect “market values” as of April 1, 2010. New value was not based on a prior assessment times some percentage of change. The next scheduled revaluation is 2015. Physical changes to property will be updated each year reflecting what was completed by April 1st. We encourage residents to allow a full inspection to ensure the accuracy of our data collection. Errors may be corrected at any time. We invite residents to contact our office at 434-7530 with questions, concerns or to discuss the assessment process.
I also encourage residents to read "Property Tax: Understanding the Math, Dispelling the Myths" by Barbara T. Reid of the NHLGC. (Reprinted with permission).

A property assessment is a generic appraisal, taking primary elements of value and applying unit costs to derive an outcome. In general terms, the elements include land area (in acreage), gross living area (building square footage), extra features and outbuildings. The unit costs are extracted from property sales data and when applied to the subject property, the assessment should reflect fair market value as improved as of April 1st, 2012 at the current level of assessment*. (See New Hampshire RSA 75:1 “How Appraised” and RSA 76:16 regarding abatement requests)
Please see Property Assessment Manual - Revaluation 2010 (16MB) for Windham’s appraisal.
If your assessment seems high, you should first review the data on file. Errors in property data contribute to inaccurate valuations. Taxpayers aggrieved by an improper valuation may appeal their assessment per State Law (RSA 76:16) and file for abatement.
* Level of Assessment – Each year, the DRA conducts a sales ratio study on each municipality to evaluate the performance of their assessment program. Tax Year 2012 study uses sales that occurred during the period October 1, 2011 and September 30, 2012. Based on this information, they will determine the average level of assessment of land and buildings as of April 1, 2012. Using qualified sales, verified through the PA-34 form (sales questionnaire) and our office, the median ratio will be determined. The median ratio is used to modify properties under review for abatement. The Town is expecting to be notified of its ratio by February/March 2013.
