Unless payable in two payments as provided by this act, on taxes remaining unpaid on the tenth day of January, interest computed at the rate as provided in section thirteen-c of this tax act from January tenth, shall be added for the first month or part thereof, and for each month or part thereof thereafter, until the return of unpaid taxes is made to the county treasurer.
The receiver shall require duplicate receipts for all payments made by him to any other officer than the county treasurer, and shall file one of such duplicates with the county treasurer on making his return.
On all such first one-half of taxes upon real estate remaining unpaid on the tenth day of January, one per centum of the amount of the said one-half of the tax will be added, and an additional one per centum will be added for each month or part thereof thereafter, until the return of the warrant to the county treasurer. The second one-half of the tax on real estate which is due on the preceding first day of December may be paid without penalty on the tenth day of May or at any time thereafter, until, but not including, the succeeding first day of June, providing the first one-half of such tax shall have been paid or shall be paid at the same time. The warrant annexed to the tax roll of any town adopting such proposition and in which taxes on real estate are payable in installments shall be made to conform to the provisions of this subdivision as hereby amended. Any such resolution of the town board providing for the collection of taxes in installments shall not take effect until thirty days after its adoption; nor until approved by the affirmative vote of a majority of the qualified electors of such town voting upon a proposition therefor, if within thirty days after its adoption there be filed with the town clerk a petition subscribed and acknowledged as provided in article seven of the town law with respect to the submission of a referendum on petition. If a petition be so filed, a proposition for the approval of such resolution shall be submitted at a general or special town election to be held not more than forty days after the filing of such petition. Notice of the election shall be given, such election held and the votes canvassed and result certified and returned in the manner provided by the town law relating to the submission of questions upon town propositions.
Notwithstanding the provisions of any general or special law to the contrary, the town board of any town may, by resolution, provide for separating school taxes from all the remainder of the taxes, to be collected pursuant to the provisions of the tax warrant, also provide for the collection and payment by the taxpayers of their school taxes at one time, and the collection and payment of all the remainder of the taxes to be collected pursuant to the provisions of the tax warrant, at another time or times, and further provide that separate bills be issued and mailed and receipts given for payment of school taxes as well as for all the remainder of the taxes to be collected pursuant to the provisions of the tax warrant.
