How Your California Take-Home Pay is Calculated
Working in California involves a complex web of payroll taxes. To determine your net pay, we look at your gross annual salary and subtract mandatory federal and state withholdings. California has some of the highest state income tax rates in the country, which are graduated based on your income level.
Key Deductions for California Workers:
Federal Income Tax: Calculated using the progressive IRS tax brackets (10% to 37%).California State Income Tax: CA uses 10 tax brackets ranging from 1% to 13.3% for the highest earners.FICA Taxes: This includes Social Security (6.2%) and Medicare (1.45%).CA SDI: State Disability Insurance is mandatory for most employees in California, currently set at 1.1% of wages.
Realistic Example Calculation
If you earn $100,000 annually in California and file as Single :
Gross Monthly: $8,333.33Federal Tax: ~$1,180.00CA State Tax: ~$500.00FICA & SDI: ~$730.00Estimated Monthly Take-Home: ~$5,923.33
What This Calculator Includes
This tool accounts for the 2024 standard deductions for both Federal ($14,600) and California ($5,363 for single filers). It also includes the mandatory SDI tax which is unique to California payrolls. Note that your actual paycheck may vary depending on voluntary contributions like 401(k), health insurance premiums, and local city taxes where applicable.
