  • 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.

Maryland Property Taxes

Taxes on real estate in Maryland account for about 35% of city budgets and 30% of county budgets, funding local services like public education and fire protection. Maryland’s average effective tax rate of 1.10% is lower than the national average. However, because Maryland generally has high property values, Maryland homeowners pay more in annual property taxes than homeowners in most other states. The median annual property tax payment in Maryland is $3,191, which ranks as the 11th highest of any U.S. state.

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 $40,000 will receive a credit for any property tax exceeding $2,580 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.

Montgomery County

The median home value in Montgomery County, which is part of the Washington, D.C. metropolitan area, is $460,100. That is the 36th highest median value of any of America’s 3,143 counties.

The median annual property tax payment in Montgomery County is $4,259.

Prince George’s County

Like Montgomery County, Prince George’s County is located just outside of Washington, D.C. However, property tax rates in Prince George’s County are much higher than those in Montgomery County.

Rank County Property Tax Rate School Rating Crimes Per 100k People


Our study aims to find the places in the United States where people are getting the most for their property tax dollars. To do this we looked at school rankings, crime rates and property taxes for every county.

As a way to measure the quality of schools, we analyzed the math and reading/language arts proficiencies for every school district in the country. We created an average score for each district by looking at the scores for every school in that district, weighting it to account for the number of students in each school. Within each state, we assigned every county a score between 1 and 10 (with 10 being the best) based on the average scores of the districts in each county.

For each county, we calculated the violent and property crimes per 100,000 residents.

Using the school and crime numbers, we calculated a community score. This is the ratio of the school rank to the combined crime rate per 100,000 residents.

We used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.

Finally, we calculated a tax value by creating a ratio of the community score to the per capita property tax paid. This shows us the counties in the country where people are getting the most bang for their buck, or where their property tax dollars are going the furthest.
