Understanding Your Net Income in California

Calculating take-home pay in the Golden State is notoriously complex due to California's progressive tax system, which features some of the highest marginal tax rates in the United States. To arrive at your net income, you must account for several layers of mandatory deductions from your gross salary.

Key Deductions in California

  • Federal Income Tax: Progressive rates ranging from 10% to 37% based on your taxable income after the standard deduction.
  • California State Income Tax: California uses a graduated system with nine tax brackets, starting at 1% and reaching up to 12.3% for high earners (plus a 1% Mental Health Services Act tax for income over $1 million).
  • FICA (Federal Insurance Contributions Act): This includes Social Security (6.2% on income up to $168,600) and Medicare (1.45% on all income).
  • CASDI: California State Disability Insurance. For 2024, the rate is 1.1%. Notably, the wage cap for SDI contributions was removed starting January 1, 2024, meaning it applies to all earned income.

Example Calculation

If you earn $100,000 annually in California as a single filer:

  1. Gross Pay: $100,000
  2. Federal Tax (Est): ~$14,260
  3. CA State Tax (Est): ~$5,980
  4. FICA (SS + Medicare): $7,650
  5. CASDI: $1,100
  6. Estimated Net Pay: ~$71,010 per year, or $5,917 per month.

Note: This calculation assumes no pre-tax contributions to 401(k) or health insurance, which would lower your taxable income and change the final result.
