Frequently Asked Questions

Each year the assessing department conducts a review of sales in Westford. Although this information is reviewed and evaluated throughout the year, the bulk of the final analysis is completed in the Fall. The overall guideline for assessing property is 90 to 110 percent assessment to sales ratio. This does not mean that there will be no occurrences of properties outside that guideline. Assessments are based on fair market value. Once the reassessment of properties has been completed, the information is submitted to the Department of Revenue and a classification hearing is held to determine the new tax rate. Please call 978-692-5504 for more information.

The classification hearing is open to the public and is a joint meeting of the Board of Assessors and the Board of Selectmen. The Board of Selectmen has the statutory authority to determine the tax rate each year. The Board of Assessors assists the Board of Selectmen during this process each year. The Department of Revenue sets the assessment date for all property. The assessment date is always behind what the actual market is. For example, the FY 2013 assessments are based on calendar year 2011 market conditions and sales. Please call 978-692-5504 for more information.

Inspections of property are conducted throughout most of the year. An inspection may occur as part of an ongoing cyclical re-inspection program, as the result of a building permit being taken out, as the result of an abatement application being made, or at the special request of any property owner. Please call 978-692-5504 for more information.

Higher property assessments do not cause higher taxes. The total municipal budget determines the money to be raised from property taxes. The tax rate can stay the same, or may even decrease based on the overall increase in property values.

It is also true that decreasing property values generally do not result in lower taxes for the same reason. Please call 978-692-5504 for more information.
