You are appealing your assessment, not your taxes. Therefore, it is recommended that you pay your taxes pending your appeal to avoid having to pay accrued interest on unpaid taxes, however it is not required to pay your taxes to file an abatement.
The assessment appeal is a formal process that can commence following the issuance of the final tax bill. An assessment appeal can be filed if you disagree with your assessment.
Generally, there must be either an error in the physical data of the property or the assessment must not be proportional to the level of assessment for all the properties within the City of Nashua.
The Assessor’s Office does not determine the total amount of taxes collected. It is the assessor’s responsibility to find the fair market value of your property. The amount of taxes you pay is determined by a tax rate applied to your property’s assessed value. The tax rate is determined by all the taxing agencies, state, city, county and school, based on the funds needed to provide the services included in the approved city budget.
The abatement form for tax year 2020 will be available here after the mailing of the final 2020 property tax bill, which will be sometime mid-November, 2020.
