New Hampshire towns, not counties, assess property. You apply in writing for an abatement to the selectmen or assessors by March 1, following the date of notice of tax.
- Recent sales of comparable homes show your assessed value is too high.
- The property record has an error in size, condition, or features.
- You apply in writing by March 1, following the date of notice of tax.
- Your assessment already reflects fair market value. A higher bill from the tax rate is not something an abatement can fix.
- You miss the March 1 filing deadline.
Read the full explanation
In New Hampshire, your town's selectmen or assessors set your property's value, and the property tax year runs from April 1 to March 31. If you think your assessment is too high, you can apply in writing for an abatement to your town's selectmen or assessors by March 1, following the date of notice of tax. The town has until July 1 after that to grant or deny your application, and if you disagree with the decision, you can appeal further to the Board of Tax and Land Appeals or to Superior Court. An appeal makes sense when your assessment is above what your home would actually sell for, or when the property record has an error. It usually will not help if your assessment already lines up with recent comparable sales and you are only unhappy with your tax bill, since the town's tax rate, not your assessment, is often what drove the increase. This is general information, not tax advice.
