On May 21st, the Board of Assessors approved two temporary policy changes due to the COVID-19 pandemic. The following questionnaires, phone interviews and submission of photos will be used in lieu of Interior inspections until further notice.

1. Building Permit - Property Record Update. This letter will be mailed to any property owner that has pulled a building permit prior to April I, 2020 which remains open. An Assessor will conduct a phone interview with each property owner and photos of the finished work can be emailed or returned with the form. (Per the revaluation contract, Vision will be handling permits after April I, 2020).

2. Residential Abatement Questionnaire and the accompanying questionnaire. Each residential property owner who has filed a 2019 abatement will be mailed a letter and questionnaire. The assigned Assessor will then follow with a phone interview and may require additional documentation such as photos.

 New Legislation Passed For Solar Energy System Exemption

The City of Nashua assesses solar equipment and it is likely that your property value will change.  the City of Nashua has recently passed legislation for the Solar Energy System Exemption that will now exempt the entire assessment for property tax purposes on the solar system, as defined in RSA 72:61.  Property owners who wish to receive this exemption must apply for the exemption by April 15th.

If you have already applied and have been granted this exemption, you do not need to reapply for this exemption.


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./DocumentCenter/View/86/News-Release---Solar-Exemption-PDF
