Mass. Gen. Laws ch. 44 § 53A
In the case of grants from the federal government or from the commonwealth, a county or municipality or agency or instrumentality thereof, upon receipt of an agreement from the grantor to provide advance payment or reimbursement to the city, town or district, the officer or department may spend the amount of the advance payment, or the amount to be reimbursed, for the purposes of the grant, subject to the approvals required by this section. Any advance payment or reimbursement shall be applied to finance the grant expenditures; provided, however, that any expenditures outstanding at the close of the fiscal year after the fiscal year in which the grantor approved the agreement shall be reported by the auditor or accountant of the city, town or district, or other officer having similar duties, or by the treasurer if there be no such officer, to the assessors, who shall include the amount so reported in the determination of the next annual tax rate, unless the city, town or district has otherwise made provision therefor. Notwithstanding the provisions of section fifty-three, any amounts so received by an officer or department of a city, town or district shall be deposited with the treasurer of such city, town or district and held as a separate account and may be expended as aforesaid by such officer or department receiving the grant or gift without further appropriation. If the express written terms or conditions of the grant agreement so stipulate, interest on the grant funds may remain with and become a part of the grant account and may be expended as part of the grant by such officer or department receiving the grant or gift without further appropriation. Any grant, subvention or subsidy for educational purposes received by an officer or department of a city, town or school district from the federal government may be expended by the school committee of such city, town or district without including the purpose of such expenditure in, or applying such amount to, the annual or any supplemental budget or appropriation request of such committee; provided, however, that this sentence shall not apply to amounts so received to which section twenty-six C of chapter seventy-one of the General Laws, and chapter six hundred and twenty-one of the acts of nineteen hundred and fifty-three, as amended, and chapter six hundred and sixty-four of the acts of nineteen hundred and fifty-eight, as amended, apply; and, provided further, that notwithstanding the foregoing provision, this sentence shall apply to amounts so received as grants under the Elementary and Secondary Education Act of 1965, ( Public Law 89-10 ). After receipt of a written commitment from the federal government approving a grant for educational purposes and in anticipation of receipt of such funds from the federal government, the treasurer, upon the request of the school committee, shall pay from the General Fund of such municipality compensation for services rendered and goods supplied to such federal grant programs, such payments to be made no later than ten days after the rendition of such services or the supplying of such goods; provided, however, that the provisions of such federal grant would allow the treasurer to reimburse the General Fund for the amounts so advanced.
