Property tax in Lake County: county, state and US
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.
| Area | Median annual tax paid | Median home value | Effective rate estimate |
|---|---|---|---|
| Lake County | $2,369 | $324,300 | 0.73% |
| California | $5,124 | $734,700 | 0.70% |
| United States | $3,119 | $332,700 | 0.94% |
Lake County’s effective-rate point estimate is 0.03 percentage points above California’s and 0.21 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.
