Property owners who wish to receive this exemption must apply for the exemption by April 15th.

Nashua Assessment Revaluation for 2013

The Assessor's Office has completed an Assessment Revaluation for 2013 (PDF). The assessed value represents an estimate of the fair market value of properties and is based on sales of similar properties that have occurred through the City of Nashua.


The mission of the Assessing Department is to ensure that all property within the City of Nashua is assessed fairly and equitably in accordance with RSA 75:1 which states in part [Assessing Departments] "shall appraise all taxable property at its full and true value in money...and shall receive and consider all evidence that may be submitted to them relative to the value of property". Accordingly, the Assessing Department's purpose is to administer NH State Laws and programs governing property assessment in an honest and professional manner.


To meet that responsibility, the Assessing Department, with a professionally trained team of appraisers, administrative personnel and state of the art technology, conduct various assessing practices to ensure an equitable and accountable real estate based assessment program. Therefore, the department is able to provide the citizens of Nashua with fair administration of programs governing property assessment, municipal efficiency and prompt response to public inquiries.
