ZIP Code 80503

ZIP code 80503, serving the Boulder area, ranks among Colorado's more affluent communities, with a median household income of $113,620 and per-capita income of $64,526. Homes here carry a median value of $755,500, yet the county-level property tax rate of 0.53% keeps annual tax bills lower than many homeowners elsewhere might expect at this price point. A combined sales tax rate of 2.90% adds little to everyday purchases. Together, these figures describe a high-earning, high-home-value ZIP where the tax structure leans on income and property wealth rather than consumption, placing it firmly in affluent territory.
