What the rate means here
At 0.54%, Boulder County taxes property more lightly than the national 0.98%. A low rate on an expensive house is not the bargain it looks like. The median bill is still $3,821, because 0.54% of $713,900 is not a small number.
It ranks #4 of 52 Colorado counties by effective rate, against a statewide 0.49%, and #2,292 nationally. The state runs from 0.62% in Broomfield County down to 0.23% in Gilpin County.
The median home costs 6.95 times the median household income of $102,772, against 3.86 nationally, so housing absorbs an unusually large share of what people here earn. Renters pay 22.1% of median income in gross rent. At 328,317 residents the county is large enough that its median blends several distinct housing markets.
