Full California income tax calculator
We're building per-state take-home calculators that account for every bracket, deduction, and local levy. For v0.1 we're shipping the top-marginal summary and source link only. Honest: we'd rather ship one polished mortgage calculator and an accurate state tax index than fake calculators for all 50 states.
