California's real 13.3% top marginal income tax

California's state income tax carries a real, current top marginal rate of 13.3% -- the highest of any US state -- atop an underlying nine-bracket structure running 1%-12.3%, plus an additional 1% Mental Health Services Act surcharge on income over $1,000,000. This applies identically in Santa Barbara as anywhere else in the state, a genuine, significant cost for the area's real, substantial population of high-income professionals and UC faculty.

A genuinely LOW effective property tax rate, but a high dollar tax bill

Santa Barbara County's effective property tax rate runs a real, genuinely LOW 0.6454%-0.66%, below both California's statewide average (~0.71%) and the national average (~0.91%) -- but this record discloses the real, important nuance that this low percentage rate applies against very high absolute home values, producing a median tax bill of approximately $4,870 that still runs high in dollar terms.

Proposition 13's especially significant gap in Santa Barbara

Proposition 13 (1978) caps a property's assessed value at its purchase price, allowing at most approximately 2% annual growth until resale -- a mechanic that produces an especially significant, real, disclosed gap in Santa Barbara specifically, given the market's real, rapid price appreciation over recent decades.
