Assessment Appeals

2025 Abatement Form

Municipalities may reduce property taxes "for good cause shown," as stated in RSA 76:16.

To establish good cause, you generally need to demonstrate that your property’s assessment is either inaccurate or unfair. This can be proven in one of the following ways:

Errors in Property Records:

• Information affecting your property’s value is incorrect. For example:
• Your property record lists 2 bathrooms, but you actually have 1 ½.
• The dimensions of your garage are recorded as 24x28, but they are 24x26.
• A survey indicates that your acreage is different from what’s recorded.

Inequitable Assessment:

• The assessed value is accurate but unfair compared to similar properties, meaning your property is assessed higher than comparable homes.

Overvaluation:

• The assessed value is too high because:
• Similar properties are selling for less than your equalized assessment (see below for details on determining this value).
• A professional appraisal shows a lower value for your property.

Financial Hardship:

• You can demonstrate poverty and an inability to pay the taxes. If you are claiming this reason, you must provide a detailed explanation of why a tax abatement is necessary, rather than pursuing other options like relocating, refinancing, or seeking public assistance.
