  • About This Answer

    To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county. more

Maryland Property Taxes

Taxes on real estate in Maryland account for a significant portion of both of city and county budgets, funding local services like public education and fire protection. Maryland’s average effective tax rate of 1.06% is about equal to the national average.

However, because property values in Maryland are also high, homeowners here pay more in annual property taxes than in most other states. Median annual property tax payments in counties in Maryland range up to $5,582.

A financial advisor in Maryland can help you understand how homeownership fits into your overall financial goals. Financial advisors can also help with investing and financial plans, including taxes, homeownership, retirement and more, to make sure you are preparing for the future.

Maryland Property Tax Assessment

Unlike most states, where local officials are responsible for property assessment, the state government oversees all property assessment in Maryland. State officials reassess properties once every three years. The goal of an assessment is to determine the fair market value of each property. The fair market value is the price the property would sell for if listed on the market.

After a reassessment, the state will notify a property owner about any change in assessed value. Property owners who believe their assessed value is incorrect have 45 days from the date of that notice to file an appeal.

For homeowners with a principal residence in Maryland, the Homestead Tax Credit limits increases in assessed property value. The state limits increases to 10%, but some city and county governments elect to use a lower limit.

Another important tax credit is the Homeowners' Property Tax Credit. The credit caps property taxes based on income level. Only households with a total gross income of less than $60,000 are eligible for this credit. As an example, a household with a gross income of $30,000 will receive a credit for any property tax exceeding $1,680 annually.

Maryland Property Tax Rates

While the state government handles property assessments in Maryland, local governments still set their own tax rates. The rates they set will depend on local revenue needs. Any time a local government increases the tax rate, it must hold a public hearing to discuss the new rate.

Tax rates in Maryland vary depending on where you live. The table below shows the average effective tax rate for each of Maryland’s 23 counties, as well as the city of Baltimore (which is independent of any county). Average effective tax rates are calculated by determining the median annual property tax payment as a percentage of the median home value.
