What is the basis for my assessment?
An assessment is an opinion of value by a licensed professional. For an assessed value
to be considered excessive or discriminatory, it must be proved that the assessment does
not fairly represent one of two standards:

1. True Market Value Standard
After a revaluation, all assessments in the municipality must be 100% of true market
value as of October 1 of the previous year. October 1 pre-tax year is the annual
“assessment date.” All evidence for a tax appeal should precede the October 1st
assessment date, especially property sales used for comparison.

2. “Common Level Range” Standard
To explain the common level range you must consider what happens after a
revaluation in your town is completed. External factors such as inflation,
recession, appreciation, and depreciation cause values to increase or decrease at
varying rates. Other factors such as physical deterioration may change
property values. If assessments are not adjusted annually, a deviation from 100%
of true market value occurs.
