The last countywide re-assessment became effective in 2017.
An assessment is a fractional portion of the fair market value of your property. In Pennsylvania, the County may choose an assessment from 1% up to 100% of market value. Washington County's ratio is 100% of market value.
The current Washington County millage is 2.43 (.00243). Example: Assessed value = 10,000 x .00243 = $24.30 at face.
