Estimate a bill and check your assessment

Census survey estimates, 2020–2024. These county medians describe a survey population; they do not establish your home’s correct assessment.

Median home value
$588,000
Median annual taxes paid
$4,929
Estimated effective rate
0.84%

Census home values, Census taxes paid. Last verified 2026-10-24. Rate = median taxes ÷ median home value. Displayed rates are rounded; calculations use the unrounded ratio.

Example at $588,000: $4,929 per year, using the Census estimate.

Is my assessment too high?

At the default market value and bill, both equal the county medians. Being above a median does not establish overassessment. Assessed or taxable values may use a different basis and cannot be compared directly with Census market values.

Appeal timing and filing

Published appeal deadline: December 31, 2026 (announced).

How to file: File a petition with the Washington County Clerk for the Property Value Appeals Board.

State guidance: After county Property Value Appeals Board review, value appeals may go to the Tax Court Magistrate Division within 30 days of the order's mailing or hearing delivery.
