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
