Maryland Property Tax Calculator
This Maryland property tax calculator estimates the annual property tax on a home using the state's median effective property tax rate, which the US Census Bureau reports as 1% of a home's value. Enter a home value to see the estimated yearly property tax at that median rate. The Census figure is derived from the median real estate taxes paid in Maryland ($3,989) divided by the median home value ($397,700), from the American Community Survey 5-year estimates. Property tax in the United States is set locally, not by the state, so your actual rate depends on your county, city, school district and any special districts, and on how your property is assessed. Two homes of the same value in different counties of Maryland can have noticeably different bills. Use this as a sound statewide benchmark, then check your county assessor for your property's assessed value and the exact local millage rate, plus any homestead or senior exemptions you qualify for. The median real estate taxes and median home value here are official Census figures; the effective rate is the simple, disclosed ratio of the two.
Maryland's median effective property tax rate is 1% of home value (Census: median tax $3,989 on a median home worth $397,700). On a $400,000 home that is about $4,000 a year.
How Maryland property tax is estimated
estimated annual property tax = home value x effective rate / 100
Maryland median effective rate = median real estate taxes / median home value x 100
= $3,989 / $397,700 x 100 = 1%
Property tax is levied by local governments, so your exact rate is set by your county and municipality, not the state. The median rate above is a benchmark; check your county assessor for the assessed value and local millage that apply to your home.
