The property owner is responsible for knowing that taxes are due and payable twice a year and notifying the Tax Office of any changes to their mailing address to ensure receiving tax bills in a timely manner.
Throughout the State of New Hampshire, the tax year runs from April 1st through the following March 31st. Assessments of your property are computed as of the value on April 1st of each tax year which appear on your property tax bill.
There are two bills issued per year; the first bill is an estimate based on the assessed value multiplied by the tax rate, then divided by two. This bill is mailed out near the end of May and is usually due July 1st every year. The State of New Hampshire Department of Revenue sets the tax rate for the year in the fall. The final bill is calculated using the new tax rate multiplied by your property's assessed value, less any payments made on the first bill. The second bill is mailed by the end of October and is usually due December 1st of each year.
(In a cost saving effort the tax office will email, phone, or fax tax information upon request)
