When are tax bills due, and how do I pay?
Most New Hampshire towns bill twice a year: the first bill is an estimate based on the prior year, and the final bill uses the new rate the state sets in the fall. Due dates vary, so check the town's tax page: Town of Londonderry Online Services.
What if I think my assessment is too high?
You can ask the town for an abatement. In New Hampshire the application is generally due by March 1 after the year's final tax bill. Londonderry's page: abatements.
Are there exemptions or tax credits?
Yes. New Hampshire towns offer credits and exemptions such as the veterans' tax credit, set and administered locally. See Londonderry's list: exemptions and credits.
Buying or refinancing in Londonderry?
Your lender counts property tax in the monthly payment it uses to qualify you, so the home's real assessment matters.
