Applying for a property tax abatement in New Hampshire involves a few steps. Here’s a general guide to help you through the process:Quick Guide: NYC Real Estate Tax Abatement | Czarnowski & Beer LLP

1. **Determine Eligibility**: Ensure you have a valid reason for requesting an abatement, such as an error in the property assessment, damage to the property, or a significant difference in the opinion of value.  The state law says that your assessment must be based on the fair market value so you must show evidence that it does not.  Thornton residents have challenged and had their assessments reduced by showing that the assessor (Avitar) did not use recent sales that would have suppressed the assessment.

2. **Obtain the Application Form**: You can find the abatement application form on the [New Hampshire Board of Tax and Land Appeals (BTLA) website] TAXPAYER’S RSA 76:16 ABATEMENT APPLICATION TO MUNICIPALITY

3. **Complete the Application**: Fill out the application form with accurate and detailed information. Make sure to include any supporting documentation, such as property appraisals or evidence of damage.

4. **Submit the Application**: File the completed application with your local municipality by the deadline. The deadline is typically March 1 following the notice of tax, but it can vary depending on when the final tax bill was sent.

5. **Municipality Review**: The municipality will review your application and issue a decision by July 1 following the notice of tax. If the municipality does not respond, the application is considered “deemed denied”.

6. **Appeal if Necessary**: If your abatement request is denied, you can file an appeal with the BTLA or the Superior Court. The appeal must be filed no earlier than the municipality’s decision or July 1, and no later than September 1 following the notice of tax.
