  • 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.

Property Assessment in Washington, D.C.

The assessed value of a property is the amount to which taxes are applied. In Washington, D.C. residential property is assessed at its full market value. That means the assessed value of a home should equal the amount it would sell for on the market.

Washington, D.C.’s Office of Tax and Revenue (OTR) is responsible for property assessments. It conducts annual assessments of all property in the District. These usually do not involve a physical inspection of the property or a full appraisal. Instead, the OTR uses mass appraisal techniques that rely on market data and other factors to reassess many properties at the same time.

While the results of a mass appraisal are generally accurate, on a given property they can be incorrect. Homeowners should review their annual reassessment notice and confirm that their assessed value is roughly equal to the expected sales price of the property.

Homeowners who believe their house has been over-assessed can file an appeal with the Real Property Tax Administration. Appeals must be filed by April 1 to be considered. Homeowners who file an appeal should be prepared to offer evidence in support of their position. Evidence may include sales prices of nearby, comparable homes or property features that the assessor failed to consider.

Washington, D.C. Property Tax Deductions and Credits

Homeowners in D.C. benefit from a number of property tax deductions and credits that greatly reduce their overall tax bill. A deduction does this indirectly, by reducing the assessed value of a property, while a credit directly reduces the taxes a homeowner has to pay. The major deductions and credits for homeowners in Washington, D.C. are described below.

  • The Homestead Deduction is available for homeowners living in a principal residence that consists of no more than five units. It reduces assessed value by $73,350. At the current property tax rate of $0.85 per $100 in assessed value, the Homestead Deduction can save a homeowner about $620 annually.
  • The Senior Citizen or Disabled Property Owner Tax Relief program reduces the property tax bill of eligible homeowners by 50%. Eligible homeowners must be at least 65 years old or disabled. Their property must be their primary residence and have no more than five units. They cannot have a total federal adjusted gross income of greater than $130,550.
  • The First-Time Home buyer Individual Income Tax Credit is a tax credit available to new homeowners in Washington, D.C. It is equal to $5,000. It is an income tax credit, so new homeowners should apply for it when completing their income taxes.
  • The Assessment Cap Credit protects homeowners from rapid increases in house prices. The credit limits increases in assessed values to 10% per year. In increases beyond that amount will be automatically counteracted by the credit, equal to the excess taxes.

Washington, D.C. Property Tax Rates

As described above, the total property tax rate in Washington, D.C. is $0.85 per $100 in assessed value. So, for example, let’s say you have a home with a market value of $300,000. It is assessed at $300,000, but since it is your principal residence, you are eligible to receive the Homestead Deduction. That will reduce your assessed value to $226,650. Applying the rate of $0.85, you would owe $1,927 annually.

That means your effective property tax rate would be 0.64%. What is an effective tax rate? It is the amount paid annually as a percentage of annual property taxes. In D.C., the average effective property tax rate paid by homeowners is 0.56%.

That is among the lowest rates in the nation. For example, in Baltimore, the average effective property tax rate is 1.65%, more than double the rate in D.C. In Virginia, the average effective property tax rate is 0.79%. In short: D.C. homeowners pay extremely low property taxes.

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.
