R.I. Gen. Laws § 44-3-58.1
The town council of the town of East Greenwich is authorized to provide, by ordinance, that the payment of any increases in property taxes on the primary residence owned and occupied by a person or persons who are sixty-five (65) years of age or older, may be deferred, interest free, by the eligible taxpayer until such time as the property is disposed of by reason of the death of all owners who are sixty-five (65) years of age or older, or by reason of transfer or conveyance, at which time the total deferred taxes will be paid to the town. An eligible taxpayer is defined as an individual who is a resident of the town of East Greenwich for income tax purposes, is sixty-five (65) years of age or older, and has resided in the primary residence located in the town of East Greenwich, for which the deferral is claimed, for a minimum of five (5) years. There is no income or means test for eligibility. In the case of a married couple, at least one spouse must be sixty-five (65) years of age or older. The deferral is optional, to be made at the request of the eligible taxpayer to the tax assessor. Any taxes so deferred will become a lien on the property. The eligible taxpayer may remove the lien at any time by paying the total taxes due, interest free. This deferral is in addition to any and all other exemptions which the taxpayer may be entitled by law. The town council of the town of East Greenwich shall establish the requirements and application and/or verification procedures for taxpayers to avail themselves of this deferment.
