RSA 76:15-a — Semi-Annual Collection of Taxes in Certain Towns and Cities. –

I. Taxes shall be collected in the following manner in towns and cities which adopt the provisions of this section in the manner set out in RSA 76:15-b. A partial payment of the taxes assessed on April 1 in any tax year shall be computed by taking the prior year's assessed valuation times 1/2 of the previous year's tax rate; provided, however, that whenever it shall appear to the selectmen or assessors that certain individual properties have physically changed in valuation, they may use the current year's appraisal times 1/2 the previous year's tax rate to compute the partial payment.
II. For the purposes of this section, the lists of assessed property shall be committed by the selectmen with a warrant under their hands and seal directed to the collector of such town no later than May 15. The collector shall mail all the bills for this partial payment no later than June 15. Partial payment of taxes assessed under this section shall be due and payable on July 1. The collector shall receive such payments, give a receipt therefor, and credit the amount paid toward the amount of the taxes eventually assessed against the property, in the same manner as prepayments under RSA 80:52-a. A payment of the remainder of the taxes assessed April 1, minus the payment due on July 1 of that year, shall be due and payable December 1. Interest charged on all taxes not paid on or before the date they are due shall be as prescribed in RSA 76:13, except that, when bills for the partial payment under this section are mailed on or after June 1, interest shall not be charged until 30 days after the last bill is mailed.
III. (a) Notwithstanding the provisions of paragraphs I and II, any municipality affected either by a change in adequate education grants or excess tax amounts, determined pursuant to RSA 198:41, or by a change of 15 percent or more in the amount of all property taxes to be raised for the current year as compared to the previous year, may apply to the commissioner of revenue administration on forms prescribed by the commissioner to adjust the 1/2 of the previous year's tax rate by an amount sufficient to collect 1/2 of the estimated increase or decrease in the city or town, school, or county taxes resulting from the change.
(b) The department of education shall certify, no later than November 15, to the commissioner of the department of revenue administration the difference in the amount of the adequate education grants and excess tax amounts between the current fiscal year and the forthcoming fiscal year for every municipality.
(c) Any municipality requesting an adjusted rate for the semi-annual bill shall submit such request to the commissioner of the department of revenue administration by April 1 prior to the issuance of the semi-annual bill.
(d) The department of revenue administration shall expedite certified adjusted rate applications.
