Property taxes in Maryland are levied locally, so the rate you actually pay depends on your county and taxing district. Across the state's 24 counties, effective rates range from about 0.65% in Talbot County to 1.46% in Baltimore city. Select your county in the calculator above to use its local effective rate instead of the statewide average.
Your tax is based on your property's assessed value, not always its full market price. The effective rate used here already reflects median assessment practices, so it gives a realistic estimate. To lower your bill, check whether you qualify for a homestead or other exemption on the Maryland property tax page.
