RRA = 0.80 (A-B)
where:
"RRA" equals the revaluation relief abatement for the eligible property;
"A" equals the tax liability produced by multiplying the constant rate factor for the municipality for the revaluation year times the net assessed value of the eligible property as it appears on the assessor's duplicate for the revaluation year; and
"B" equals the tax liability produced by multiplying the general tax rate for the municipality for the base year times the net assessed value of the eligible property as it appeared on the assessor's duplicate for the base year.
