How this is calculated
The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.
About Loudoun County, VA
Loudoun County's 0.850% effective property tax rate lands above Virginia's 0.601% median and edges past the national figure of 0.794%, placing it 21st among the state's 133 counties. That ranking signals a relatively heavy tax environment compared with most of Virginia, though the gap with the national norm is narrow. On a median home value of $743,800, owners pay roughly $6,325 a year in real-estate taxes. Households here earn a median of $181,765, with per-capita income at $71,986, so the tax bill absorbs a smaller share of income than the raw rate might imply. Communities such as Ashburn, Sterling, and Leesburg anchor this prosperous corner of Northern Virginia, where high home values and strong earnings coexist with tax rates that run above both state and national benchmarks.
