How to Use This California Paycheck Calculator
This California paycheck calculator estimates your 2026 net take-home pay after federal income tax, California state income tax, California SDI (State Disability Insurance), Social Security, and Medicare. The state is locked to California; use the generic paycheck calculator for other states.
Enter your gross salary or hourly wage, filing status, pay frequency, and any pre-tax deductions (401(k), health insurance). Results update instantly with a full per-paycheck and annual breakdown. California has no local income taxes, so no locality selection is needed.
How California State Income Tax Works
California uses a progressive bracket systemwith ten brackets ranging from 1% to 13.3% — the most brackets and the highest top rate of any state in the US. Like the federal system, only the dollars within each bracket are taxed at that bracket's rate. Your marginal rate applies to the next dollar earned, while your effective rate (total CA tax ÷ income) is always lower.
- Standard deduction — $5,592 for single filers and $11,184 for married filing jointly. This is much lower than the federal standard deduction, meaning more income is subject to CA state tax.
- 401(k) and Section 125 deductions — recognized as pre-tax for CA income tax. A $20,000 401(k) contribution saves an additional ~$1,860 in CA state income tax at the 9.3% bracket.
- 9.3% bracket — applies from $72,724 to $371,479 for single filers. Most working Californians with moderate-to-high incomes fall in this bracket. The marginal rate jumps sharply once income crosses $72,724.
- 13.3% top rate — applies on income above $1,000,000. California is one of only a few states with a rate exceeding 13%, making it a significant factor in high-earner tax planning.
California SDI — State Disability Insurance
California workers pay SDI (State Disability Insurance) at 1.1% of gross wages with no wage cap in 2026. This is unique — most states that have SDI or similar programs cap the taxable wage base. California eliminated its SDI wage cap starting in 2024, meaning every dollar of wages is subject to the 1.1% SDI rate.
SDI is withheld from employee paychecks (employees pay it; employers do not match it). It funds two programs:
- Short-Term Disability Insurance — pays 60–70% of wages (up to a weekly cap) if you cannot work due to illness, injury, or pregnancy for up to 52 weeks.
- Paid Family Leave (PFL) — pays 60–70% of wages for up to 8 weeks to bond with a new child or care for a seriously ill family member.
The calculator shows SDI as a separate line item. On a $100,000 salary, SDI costs $1,100 per year ($42.31 biweekly on a 26-period schedule).
FICA Taxes — Social Security and Medicare
FICA is federal and applies on every California paycheck in addition to CA state tax and SDI.
- Social Security: 6.2% on wages up to $176,100 (2025) or $184,500 (2026). No further withholding once you cross the wage base for the year.
- Medicare: 1.45% on all wages with no cap. Additional 0.9% Medicare surtax on wages above $200,000 single / $250,000 MFJ.
- Employer match: your employer matches Social Security and base Medicare; the Additional Medicare surtax is employee-only.
Step-by-Step Example — $100,000 California Single Filer
- Gross annual pay: $100,000
- Federal taxable income: $100,000 − $16,100 standard deduction = $83,900. Federal income tax: ~$13,170.
- CA state taxable income: $100,000 − $5,592 standard deduction = $94,408. CA income tax: ~$6,000–$6,200.
- CA SDI: $100,000 × 1.1% = $1,100.
- FICA: $100,000 × 7.65% = $7,650.
- Total withholding: ~$27,920–$28,120.
- Annual net take-home: ~$71,880–$72,080 (~$2,765 biweekly).
Compare this with a Texas or Florida resident at the same salary — they keep roughly $7,000–$8,000 more per year with no state income tax or SDI. Use the California income tax calculator to see a full annual tax breakdown.
How to Reduce California Tax Withholding
Pre-tax payroll deductions save both federal and California state income tax simultaneously. However, note that HSA contributions do not reduce California taxable income — California does not conform to the federal HSA tax exclusion.
- Max your 401(k) — $23,500 in 2026 ($31,000 age 50+). For a CA resident in the 9.3% bracket and 22% federal bracket, every $1,000 contributed saves $313 in combined taxes (22% federal + 9.3% CA = 31.3%). Maxing at $23,500 saves ~$7,355.
- Health insurance premiums — employer-sponsored health insurance premiums paid pre-tax through a Section 125 cafeteria plan reduce both federal and CA taxable wages, and also avoid FICA.
- Dependent care FSA — up to $5,000 per household reduces federal and CA taxable wages. At the 9.3% CA bracket + 22% federal, $5,000 saves ~$1,565.
- HSA caution — unlike federal and most states, California taxes HSA contributions and investment earnings. An HSA reduces federal taxes but not CA taxes. Payroll HSA contributions still avoid FICA (7.65% savings), making them worthwhile, but budget for the CA tax on contributions.
- Adjust your DE-4 form— California's withholding certificate (Form DE-4) works like the federal W-4. File a new one whenever your filing status or deductions change to avoid over- or under-withholding on California wages. Use this paycheck calculator to verify accuracy.
State-Specific Payroll Deductions in California
California workers face two mandatory state-level payroll deductions beyond state income tax withholding — more than any other state in this guide:
- California State Disability Insurance (SDI) — 1.1%: Withheld at 1.1% of all wages with no wage capstarting in 2024 (previously capped at ~$145,000). SDI is an employee-only deduction (employers do not match it) and is labeled "CA SDI" on the paystub. For a $100,000 salary, SDI costs $1,100/year.
- California Paid Family Leave (PFL) — funded via SDI: PFL benefits are paid from the SDI fund — there is no separate PFL line on the paystub. The single 1.1% SDI deduction funds both short-term disability and paid family leave claims. PFL provides up to 8 weeks of partial pay (60–70% of wages, up to a weekly maximum) for bonding with a new child or caring for a seriously ill family member.
California has no local income taxes and no additional statewide payroll taxes beyond the SDI/PFL rate described above. No California city or county levies a local payroll income tax on individual workers.
How to Fill Out the California Withholding Certificate (Form DE-4)
California uses Form DE-4(Employee's Withholding Allowance Certificate) as the state equivalent of the federal W-4. Since California's brackets and standard deduction differ significantly from federal law, the DE-4 is separate from and does not replace the federal W-4. Key elements of the Form DE-4:
- Filing status: Single, Married (both spouses working), Married (spouse not working), or Head of Household. Your status determines the withholding table the employer uses.
- Withholding allowances: Each allowance reduces the income subject to withholding. The California EDD Worksheet on the DE-4 helps you calculate the appropriate number of allowances based on your deductions and credits.
- Additional withholding: You can request an additional flat dollar amount withheld per paycheck for California — useful if you have significant side income, rental income, or self-employment income in addition to W-2 wages.
- Exempt from withholding: If you had no CA income tax liability last year and expect none this year, you may claim exempt. This must be renewed annually.
- HSA note: California does not conform to the federal HSA tax exclusion, so even though your federal W-4 accounts for HSA deductions, your CA taxable wages will still include HSA contributions. The DE-4 does not have an HSA adjustment — your employer calculates CA withholding before removing HSA amounts.
If no DE-4 is on file, California law requires employers to withhold as if you are single with zero allowances — the maximum possible withholding. Submit the DE-4 to your employer whenever your filing status, dependents, or deductions change. The DE-4 is available from the California EDD website.
