ZIP Code 20015

ZIP code 20015, within Washington, ranks among the nation's wealthiest. A median household income of $250,001 and per-capita income of $138,482 place its residents far above average earners. Homes here carry a median value of $1,245,600, yet the county-level effective property tax rate sits at just 0.58%, so the annual tax bill stays contained even on a seven-figure house. Add a 6.00% combined sales tax, and the overall picture is one of high affluence paired with a comparatively gentle tax load — substantial earnings and valuable property, taxed at rates that don't consume an outsized share of either.
