Taxes in San Francisco
California levies the highest top marginal state income tax rate in the US at 13.3% -- an identical statewide figure to this project's Los Angeles record, since this is a state-level tax -- and San Francisco's own comparatively moderate effective property tax rate (~1.18%) does not offset it, given the city's genuinely extreme home values and rent.

California's income tax runs nine brackets from 1% to 12.3%, plus a distinct 1% Mental Health Services Act surcharge on taxable income over $1,000,000 (not doubled for joint filers), producing a real 13.3% top marginal rate -- the highest of any US state. This is a real, meaningful, and current cost for San Francisco's genuinely tech/finance-heavy, often higher-earning workforce specifically, and this record does not understate it.
Property Tax Runs a Comparatively Moderate Percentage, but the Dollar Bill Is High
As detailed in full on the property-taxes topic page, San Francisco's effective secured property tax rate (~1.18%) runs comparatively moderate as a PERCENTAGE, thanks to Proposition 13's assessed-value cap for long-time owners. But given San Francisco's genuinely extreme home values (Redfin's median: $1.7 million as of June 2026), the resulting DOLLAR tax bill for a new buyer at that rate still runs high in absolute terms -- a real, disclosed distinction between percentage rate and dollar cost this record states plainly.
A High Statewide Sales Tax Base Rate, Plus San Francisco-Specific Local Add-Ons
California's statewide base sales tax rate (7.25%) is itself among the highest in the country before any local add-ons. This pass did not independently confirm the current specific combined state-plus-local sales tax rate for San Francisco specifically; confirm the current combined rate directly, since city- and district-level add-ons vary across California jurisdictions.
A Genuinely High-Tax City Overall, Compounding an Already-Extreme Cost of Living
San Francisco's real, current combination of California's highest-in-the-nation income tax rate, genuinely extreme housing and rent costs, and a real (if comparatively moderate-percentage) property tax means the city's overall tax-and-cost burden runs among the highest of any US market -- this record states this combination plainly rather than letting any single moderate-sounding figure (like the property tax percentage) obscure the fuller picture.
