How California Income Tax Works
California uses a progressive tax system where your income is taxed at different rates as it climbs through the brackets. Only the income in each bracket is taxed at that bracket's rate.
Example: $75,000 income (Single filer)
- Gross income: $75,000
- Standard deduction: -$5,363
- Taxable income: $69,637
- Tax calculation:
- First $10,412 @ 1% = $104
- Next $14,272 @ 2% = $285
- Next $14,275 @ 4% = $571
- Next $15,122 @ 6% = $907
- Next $14,269 @ 8% = $1,142
- Remaining $1,287 @ 9.3% = $120
- Total CA tax: $3,129
- Effective rate: 4.17% (even though top bracket is 9.3%)
