Explainer: How property assessors affect your tax bill — and what they don’t do

An unidentified speaker, identified in the transcript only as the presenter, explained that assessors determine property values but do not set tax rates or collect taxes. "Assessors don't set tax rates," the presenter said, adding, "Assessors don't chase tax dollars."

The presenter said property tax is produced by a formula in which assessors influence only one variable: value. Local governing bodies set budgets and then set tax rates to generate the dollars needed to meet those budgets. "Assessors only affect 1 of these variables, the value," the speaker said, and noted that if everyone’s assessed value fell, tax rates would be adjusted so the same revenue requirement could be met.

To make the point plain, the speaker used a restaurant analogy: with a $100 bill and diners ordering different-priced meals, the assessor’s role is like deciding who ordered the caviar and who ordered the hot dog so each pays a fair share. The presenter said this is why assessors aim for equity and accuracy rather than targeting tax collections.

On method, the presenter described how assessors use comparable sales and property characteristics to set values: "the assessor looks at similar properties that have sold, their sale bridal, and the terms and conditions of each sale," and factors such as square footage, age, number of bathrooms and finished basements can produce meaningful value differences. Assessors also maintain databases of local real estate information to improve precision.

The presenter said changes in assessed value typically come from market sales or material property changes such as remodeling a kitchen or finishing a basement, and emphasized that assessed values are the result of a system designed to deliver fairness and accuracy. The talk closed by restating that assessors are "just fellow taxpayers" whose primary goal is equitable valuation.
