R.I. Gen. Laws § 44-33.5-7

The board, officer or department supervising the senior taxpayer’s service must certify to the assessor the hour of service performed by the taxpayer before the actual tax for the fiscal year is committed. The certification must state the amount actually earned as of that time. Services performed after that date shall be credited toward the next fiscal year’s actual tax bill to the extent they are consistent with the program rules established by the town administrator. A copy of the certification must also be provided to the senior program participant prior to the actual tax bill being issued.
