Compare Census estimates and read the sampling notes

Census ACS 2020–2024 estimates for owner-occupied homes. The median annual tax paid is a historical survey estimate, not a quote for this year’s bill.

AreaMedian annual tax paidMedian home valueEffective rate estimate
Colusa County$2,426 $393,400 0.62%
California$5,124 $734,700 0.70%
United States$3,119 $332,700 0.94%

Colusa County’s effective-rate point estimate is 0.08 percentage points below California’s and 0.32 percentage points below the US estimate.

Effective rate = median annual real estate taxes paid (B25103) ÷ median owner-occupied home value (B25077). State and US figures use their own Census medians, not averages of counties. These ratios are not rates set by law or medians of individual tax rates. Differences are not tests of statistical significance. Bounded or missing estimates stay unavailable.
