The median property tax here is $5,580 annually—more than double the national median of $2,690—reflecting the county's median home value of $779,000.

Middle of the pack across California

Sonoma ranks near the state median for effective tax rates, sitting just barely above California's 0.714% average. Its median annual tax of $5,580 exceeds the state median of $4,045, placing it firmly in the upper half of California counties by total tax burden.

Higher taxes than similar Wine Country peers

Ventura County to the south carries a similar rate at 0.693%, while smaller inland counties like Sutter (0.779%) and Tulare (0.730%) maintain comparable or slightly higher effective rates despite lower home prices.

A $779,000 home costs $5,580 yearly

Among California's pricier counties

Sonoma vs. nearby North Coast

Renters in Sonoma pay $2,093 monthly versus $1,247 in nearby Tuolumne County—a 68% difference—while median incomes in Sonoma ($102,840) are proportionally higher. This premium reflects Sonoma's coastal appeal and stronger regional economy compared to inland neighbors.

A Sonoma household earning $102,840 annually spends roughly $24,960 on rent (24.4% of income) or $27,648 on mortgage payments. Housing consumes nearly a quarter of household income, leaving limited flexibility for savings, childcare, and other essentials.
