These rules are the same in every Maryland county. Each link opens the rule on the Maryland page, where the Maryland-wide sources are listed.
What do Washington County property taxes and assessments look like?
Figures from public records and the Census, each with its source. They describe the county's homes as a group, not the value of any one home.
How much could a lower assessment save on Washington County property taxes?
Tax rate used: $1.04 per $100 of assessed value (county and State rates, fiscal 2025-26).
| Example | Tax saved |
|---|---|
| $10,000 less assessed value | $104 a year |
| 10% less on a home assessed at $190,700 (the county's 25th percentile) | $198 a year |
| 10% less on a home assessed at $273,200 (the county's median) | $284 a year |
| 10% less on a home assessed at $370,600 (the county's 75th percentile) | $385 a year |
These are examples: the tax rate times a lower assessed value. Exemptions, credits, caps and phase-ins can make the real change smaller. This is not a prediction for any home. Rate source: Local Real Property Tax Rates in Maryland, FY 2022-FY 2026 (Department of Legislative Services).
