How this calculator works
PaycheckWise estimates your California take-home pay using published 2026 federal and California tax brackets, FICA rates, and the California SDI rate. The calculation engine:
- Annualizes your gross wages from salary, hourly, and bonus inputs.
- Applies pre-tax deductions to reduce wages subject to federal, state, and (where applicable) FICA tax.
- Estimates federal income tax using filing-status brackets and W-4 adjustments.
- Calculates Social Security (6.2% up to the wage base) and Medicare (1.45% plus 0.9% above thresholds).
- Calculates California state income tax using FTB brackets and the standard deduction.
- Applies California SDI at 1.3% with no wage cap for 2026.
- Subtracts post-tax deductions and extra withholding, then divides by your pay frequency.

- Medicare — 1.45% of all wages, plus 0.9% Additional Medicare for high earners.

Example: $100,000 salary in California (single)
A single filer earning $100,000 annually in California with no pre-tax deductions and standard W-4 settings will see roughly the following annual breakdown:
- Federal income tax: ~$13,000–$14,000
- Social Security: $6,200
- Medicare: $1,450
- California state tax: ~$4,500–$5,500
- California SDI: $1,300
Net take-home is approximately $72,000–$74,000 annually, or about $2,770–$2,850 per biweekly paycheck. Adjust the calculator for your actual deductions and W-4 settings.
Pre-tax deductions and California paychecks
Traditional 401(k) contributions reduce wages subject to federal and California income tax, but not Social Security, Medicare, or SDI. Section 125 plans (HSA, FSA, health/dental/vision insurance) typically reduce wages for all five taxes. Roth 401(k) contributions are post-tax — they reduce your paycheck but do not lower current tax withholding.
Deduction tax treatment varies by plan. Confirm with your payroll provider or HR team.
Frequently asked questions
How is my California paycheck calculated?+
Your California paycheck is calculated by subtracting federal income tax, Social Security (6.2%), Medicare (1.45%), California state income tax, California SDI, pre-tax deductions (such as 401(k), HSA, health insurance), post-tax deductions, and any extra withholding from your gross pay. Pay frequency determines how the annual tax estimate is split across paychecks.
What taxes come out of a California paycheck?+
California paychecks include federal income tax withholding, Social Security and Medicare (FICA), California state income tax withholding, and California State Disability Insurance (SDI). Additional Medicare tax may apply to higher earners.
What is California SDI?+
California State Disability Insurance (SDI) is a mandatory payroll deduction that funds short-term disability and Paid Family Leave benefits. For 2026 the SDI rate is 1.3% of wages with no wage cap.
Does California tax bonuses?+
Yes. Bonuses are supplemental wages and are subject to federal, state, FICA, and SDI taxes. California typically withholds at a flat supplemental rate, but the actual amount owed is determined at tax time.
How much is a biweekly paycheck on a $100,000 salary in California?+
For a single filer in California with no pre-tax deductions, a $100,000 salary generally yields roughly $2,500–$2,800 per biweekly paycheck after federal, state, FICA, and SDI taxes. Use the calculator above for a personalized estimate that includes your deductions.
Why is my California paycheck lower than expected?+
Common reasons include higher federal or state withholding from your W-4 settings, pre-tax deductions for 401(k) or health insurance, post-tax items like Roth 401(k), garnishments, or local benefits. California SDI also reduces take-home pay.
Does 401(k) reduce my California paycheck taxes?+
Traditional 401(k) contributions reduce your federal and California taxable income, lowering income tax withholding. They do not reduce Social Security, Medicare, or SDI taxes. Roth 401(k) contributions are post-tax and do not reduce current income tax withholding.
Is this paycheck calculator exact?+
No. This is an estimate using published 2026 tax brackets and standard withholding logic. Your actual paycheck depends on your employer's payroll system, exact W-4 settings, benefit elections, local taxes, and any tax credits you qualify for.
