California Tax Calculator
Estimate your California income tax, federal tax, SDI, and total take-home pay for tax year 2025.
🌴 What is the California Income Tax?
California imposes a state income tax on all residents using a progressive bracket system with 10 tax rates ranging from 1% to 13.3%. The 13.3% top rate makes California the highest state income tax jurisdiction in the United States as of 2025. This rate applies only to income above $1 million and includes the 1% Mental Health Services Tax (Proposition 63) that was added in 2004.
Beyond state income tax, California workers pay California SDI (State Disability Insurance) at 1.1% on all wages with no cap since Senate Bill 951 took effect in January 2024. This funds California's paid family leave and short-term disability programs. On top of CA taxes, residents also pay federal income tax and FICA (Social Security at 6.2% and Medicare at 1.45%). For a $100,000 earner, the combined state and federal tax burden is typically 20-25% of gross income.
A common source of confusion is California's standard deduction. For 2025, single filers can deduct $5,202 from their California return, but $15,000 from their federal return. This gap means your California taxable income is about $9,800 higher than your federal taxable income for the same gross income. Workers who contribute to a 401(k) or traditional IRA receive a federal deduction for those contributions but not a California deduction, increasing California taxable income further.
This calculator uses 2025 California FTB (Franchise Tax Board) tax brackets and the 2025 federal brackets from the IRS. It provides an estimate for wage earners with standard deductions. If you have significant itemized deductions, capital gains, business income, or other adjustments, use the official California FTB online estimator or consult a California CPA for precise calculations.
📐 Formula
CA Tax = ∑ ratei × (min(Taxable, bi+1) − bi)
Taxable Income = Gross Income − CA Standard Deduction ($5,202 single / $10,404 married for 2025)
ratei = CA marginal rate for bracket i (1%, 2%, 4%, 6%, 8%, 9.3%, 10.3%, 11.3%, 12.3%, 13.3%)
bi = Lower bound of bracket i
CA SDI = Gross Income × 1.1% (unlimited wage base per SB 951)
Federal Tax = Applied separately using 2025 IRS brackets after $15,000 standard deduction (single)
FICA = Social Security: 6.2% on first $176,100 + Medicare: 1.45% on all income
Example: Single, $100,000 income: CA taxable = $94,798. CA tax = 1%x$10,756 + 2%x$14,743 + 4%x$14,746 + 6%x$15,621 + 8%x$14,740 + 9.3%x$24,192 = $6,060. Plus federal ~$13,700, SDI $1,100, FICA $7,650 = total $28,510 (28.5% effective rate).

💡 Example Calculations
Example 1 - Single Filer at $75,000
Single California resident earning $75,000 per year in 2025
1
CA taxable income = $75,000 - $5,202 = $69,798. This falls across brackets 1% through 8% (the 9.3% bracket starts at $70,606).
2
CA tax: 1%x$10,756 + 2%x$14,743 + 4%x$14,746 + 6%x$15,621 + 8%x$13,932 = $108 + $295 + $590 + $937 + $1,115 = $3,045 CA state tax. Effective CA rate: 4.06%.
3
Federal tax (standard ded $15,000): taxable $60,000. Federal tax approximately $8,600. SDI: $75,000 x 1.1% = $825. FICA: $5,738 (SS: $4,650 + Medicare: $1,088).
4
Total tax = $3,045 + $8,600 + $825 + $5,738 = $18,208. Net take-home = $75,000 - $18,208 = $56,792. Total effective rate: 24.3%.
Result = $56,792 net annual income at 24.3% total effective rate

Married filing jointly at $200,000 combined California income in 2025
1
CA taxable income = $200,000 - $10,404 = $189,596. This falls in the 9.3% bracket range for CA married filers ($141,212 to $721,318).
2
CA tax: 1%x$21,512 + 2%x$29,486 + 4%x$29,492 + 6%x$31,242 + 8%x$29,480 + 9.3%x$48,384 = $215 + $590 + $1,180 + $1,875 + $2,358 + $4,500 = $10,718 CA state tax. Effective CA rate: 5.36%.
3
Federal tax (standard ded $30,000): taxable $170,000. Federal tax approximately $28,400. SDI: $200,000 x 1.1% = $2,200. FICA: $13,492 (SS on each worker up to wage base, Medicare unlimited).
4
Total tax = $10,718 + $28,400 + $2,200 + $13,492 = $54,810. Net take-home = $200,000 - $54,810 = $145,190. Total effective rate: 27.4%.
Result = $145,190 net annual income at 27.4% total effective rate

What are the California income tax brackets for 2025?
California has 10 tax brackets for 2025 (single filer rates): 1% on $0-$10,756; 2% on $10,756-$25,499; 4% on $25,499-$40,245; 6% on $40,245-$55,866; 8% on $55,866-$70,606; 9.3% on $70,606-$360,659; 10.3% on $360,659-$432,787; 11.3% on $432,787-$721,314; 12.3% on $721,314-$1,000,000; and 13.3% on income above $1,000,000. Married filing jointly brackets are approximately double the single amounts.
Does California have a standard deduction?
Yes, but it is much smaller than the federal standard deduction. For 2025, the California standard deduction is $5,202 for single filers and $10,404 for married filing jointly. The federal standard deduction for the same year is $15,000 single and $30,000 married. This gap means CA residents have higher taxable income on their state return than their federal return for the same gross income.
What is California SDI and do I have to pay it?
California SDI (State Disability Insurance) is a mandatory payroll deduction for all employees working in California. For 2025, the rate is 1.1% on all wages with no cap on the wage base (since SB 951 effective January 2024). It funds California's Paid Family Leave (PFL) and State Disability Insurance programs. Self-employed individuals can opt in voluntarily. There is no way for regular employees to opt out.
How much California income tax do I owe on $50,000?
On $50,000 as a single filer in 2025: CA taxable income = $50,000 - $5,202 = $44,798. Tax = 1%x$10,756 ($108) + 2%x$14,743 ($295) + 4%x$14,746 ($590) + 6%x$4,553 ($273) = approximately $1,266. Effective CA rate is about 2.5%. After adding federal tax ($4,400), SDI ($550), and FICA ($3,825), total taxes are approximately $10,000, leaving a net of around $40,000.
Does California tax retirement income like Social Security?
California does not tax Social Security benefits, unlike the federal government which taxes up to 85% of benefits for higher-income recipients. However, California fully taxes pension income, 401(k) distributions, traditional IRA withdrawals, and most other retirement income. Roth IRA distributions are not taxed by either California or the federal government if the distribution is qualified.
What is California's top marginal tax rate and who pays it?
California's top marginal rate is 13.3%, which applies to taxable income above $1,000,000 for single filers (above $2,000,000 for married filing jointly). This rate includes the base 12.3% rate plus the 1% Mental Health Services Tax (Proposition 63, 2004). It is the highest state income tax rate in the United States. The 12.3% rate applies to income between $721,314 and $1,000,000.
If I work remotely from California for an out-of-state company, do I owe California taxes?
Yes. If you are a California resident, California taxes your worldwide income regardless of where your employer is located. If you live in California and work remotely for a company headquartered in Texas, your income is still California-sourced income for state tax purposes. The key test is residency, not where your employer operates. If you moved out of California mid-year, you owe CA tax only on income earned while a resident.
How does California handle capital gains taxes?
California taxes capital gains as ordinary income, unlike the federal government which has preferential long-term capital gains rates of 0%, 15%, or 20%. A California resident who sells stocks held for more than one year pays the same 1-13.3% state rate as on regular income. Combined with the federal long-term capital gains rate (15-20%) and the 3.8% Net Investment Income Tax (NIIT) for higher earners, California investors can face effective combined rates of 30-37% on long-term gains.
What is the California Young Child Tax Credit?
California offers a Young Child Tax Credit of $1,117 per qualifying child under age 6 for tax year 2025. It is refundable, meaning you receive it even if you have no tax liability. It phases out at higher income levels. California also offers an Earned Income Tax Credit (CalEITC) for lower-income workers, which can further reduce state tax owed. These credits are not reflected in this basic calculator but are important for eligible families.
Why is my California paycheck tax withholding different from what this calculator shows?
This calculator estimates annual tax liability using the standard deduction. Paycheck withholding is based on your W-4 elections, which may include additional allowances, estimated deductions, or extra withholding amounts you specified. Withholding is also affected by your pay frequency (biweekly vs monthly produces different tables). The difference between total annual withholding and actual tax owed is reconciled when you file your tax return, either as a refund or additional tax due.
