RSA 76:15-c — Collection of Property Taxes in Certain Municipalities. –

I. Any municipality with a fiscal year of July 1 to June 30 of the following year which collects its property taxes semi-annually in December and June may adopt the provisions of this section by majority vote of the legislative body of the municipality. Prior to the vote each municipality shall hold a public hearing on the adoption of these provisions. If adopted by the municipality, the provisions of this section shall be effective on April 1 following the vote.
II. If the provisions of this section are adopted by the municipality, the municipality shall begin adjusting the 2 due dates for the partial payment and the payment of taxes forward one month a year for 6 years until the final collection dates are on July 1 for the partial payment and December 1 for the balance of the payment for the year of assessment, still funding the period from July 1 through June 30 of the following year. During the conversion years a partial payment of the taxes assessed on April 1 in any year shall be computed by taking the prior year's assessed value times 1/2 of the prior year's tax rate; provided, however, that whenever it shall appear to the assessor that certain individual properties have physically changed in valuation, the assessor may use the current year's assessed value times 1/2 of the previous year's tax rate to compute the partial payment.
III. Interest charged on all taxes not paid on or before the date they are due shall be at the rate prescribed in RSA 76:13. Interest shall accrue after the due dates of each payment due.
IV. For purposes of abatement filing periods, the mailing date for the final notice of tax for second payment of taxes shall be used for calculating the period.
V. After completion of the conversion years, RSA 76:15-a shall regulate the assessment and collection of property taxes.
