Property Tax Bills Across Washington County, Maryland
Property tax bills in Washington County, Maryland are calculated by applying the local tax rate to a home’s assessed market value. The assessed value is based on what the property is worth, not what the owner paid, and it can change over time as market conditions shift. Homes with higher assessed values generally face larger tax bills, while lower-valued homes pay less.
Several factors influence the final bill, including the property’s location, home characteristics, and any changes in local assessments. In Washington County, the median home price is $235,900, which helps explain why tax bills can vary widely from one homeowner to another. The 25th percentile tax bill is $1,488, while the 75th percentile is $2,918 and the 90th percentile is $3,831.
