§ 11 Assessed Value Calculation Rules
This law tells you how to compare property tax numbers when the way the value is measured changed in 1981‑82, and it gives a simple way to switch between the old dollar‑per‑$100 method and the newer percent‑of‑full‑value method.
A homeowner had a house worth $200,000 in 1980‑81. The town charged $2 for every $100 of assessed value. In 1982‑83 the town switched to charging 0.8 % of the full value. How do we know the two rates are the same?
First we turn the old $2 per $100 (which used a 25 % assessment) into a percent of full value using the conversion factor from the law. The result matches the new 0.8 % rate, so the homeowner pays the same amount each year.
Old‑rate (dollars per $100 assessed) × 0.0025 = New‑rate (percent of full value) New‑rate (percent of full value) × 400 = Old‑rate (dollars per $100 assessed)
Convert the 1980‑81 rate of $2 per $100 assessed to a percent of full value.
Result: 2 × 0.0025 = 0.005, or 0.5 % of full value. (If the town later used 0.5 % of full value, the two rates are equivalent.)
