New York Consolidated Laws, Village Law - VIL § 14-1430 Tax for unpaid assessments

The board of trustees shall include in the annual tax levy the principal or interest accruing during the same fiscal year upon bonds, notes or certificates of indebtedness issued on account of default in the payment of local assessments under this article, and shall levy the same upon the lots or parcels in default.

Such principal shall be apportioned among the lots or parcels in default so that the tax thereon will be the same as if an equal portion of the assessment were then to be paid.  Interest on an unpaid assessment shall be added to such tax at the rate payable by the bond, note or certificate of indebtedness, which must be computed to the time when the principal or an instalment will become due;  or if no principal will become due during the fiscal year, then the interest accruing during that year upon the assessment must be levied upon such lot or parcel.
