Arlington Assessments Up 3.2%, Tax Rate Up Too
In January, Arlington announced that residential property tax assessments increased by an average of 3.2%, higher than the ~1% increase in market values that I calculated for 2025. Last year’s 3.7% increase came in about half as high as the increase in market values I calculated for 2024, so Arlington had some catching up to do.
Arlington will increase the tax rate by 1.5 cents per $100 to $1.048 per $100, which comes out to a tax bill of 1.048% of your assessed value.
Assessed Values Remain Lower Than Market Values
Homes that sold in Arlington in 2025 sold for an average of 7.9% more (median 7.7%) than their most recent tax assessed value.

Detached and townhouse/duplex homes sold for an average of 10.1% more (median 10.1%) than their recent tax assessed value

Arlington undervalues detached/townhouse properties in the 22205 zip code the most, with 2025 market values an average of 13.4% higher than their assessed value. Owners in 22205 would pay roughly $2,000 more in annual property taxes, on average, if they were assessed at market value.

Arlington is best at assessing the value of condos in 22201 (most of the Rosslyn-Ballston Corridor), with market values averaging just 3.8% more than their recent assessed value, the lowest of any property type/zip code category. This is not surprising, given the number of data points they have and how similar/consistent many of those data points are.

On average, Arlington homeowners would pay about $1,000 more per year in property taxes if Arlington’s assessed values were equal to market values
