How Much Tax Is Taken Out of a Paycheck in California? (2026)
By Muzammal Amin | Last verified September 2, 2026 | California, USA | Tax year 2026
There is no single percentage taken out of every California paycheck. A typical W-2 employee can have five main tax lines: federal income-tax withholding, Social Security, Medicare, California Personal Income Tax (PIT) withholding, and California State Disability Insurance (SDI). The exact total depends on pay, filing information, benefits, deductions and year-to-date wages.
For wages that are fully subject to Social Security, Medicare and California State Plan SDI, the three fixed-rate employee payroll taxes start at 8.95% combined in 2026: 6.2% Social Security + 1.45% Medicare + 1.3% California SDI. Federal and California income-tax withholding are added on top and are variable. The 8.95% figure is not a universal all-in tax rate because Social Security has an annual wage cap, Additional Medicare can begin later in the year, and some wages or employees have special treatment.

What taxes come out of a California paycheck?
| Paycheck tax | 2026 rate | What determines it | Authority |
| Federal income-tax withholding | Variable | Your pay, pay frequency and Form W-4 | IRS Publication 15-T (2026) |
| Social Security | 6.2% | Covered wages up to $184,500 in 2026 | IRS / SSA |
| Medicare | 1.45% | Covered wages; no wage-base ceiling | IRS |
| Additional Medicare withholding | +0.9% | Employer begins after wages paid to you exceed $200,000 in the calendar year | IRS |
| California PIT withholding | Variable | California withholding schedules + DE 4 elections | California EDD |
| California SDI | 1.3% | Wages subject to State Plan SDI; no taxable wage ceiling | California EDD |
California also has Unemployment Insurance (UI) and Employment Training Tax (ETT), but the California EDD identifies those as employer contributions. They are not ordinary employee UI/ETT deductions from a W-2 paycheck. California PIT and SDI are the two state payroll taxes normally withheld from employees.

The fastest way to understand your paycheck: fixed taxes vs. variable withholding
The easiest mistake is to treat every deduction as one tax percentage. Payroll actually combines different systems.
Fixed-rate payroll taxes
For most W-2 employees, Social Security, Medicare and California SDI are the easiest lines to check because their statutory rates are known. In 2026:
• Social Security: 6.2% of covered employee wages until year-to-date Social Security wages reach $184,500.
• Medicare: 1.45% of covered wages with no wage cap.
• California SDI: 1.3% of wages subject to the State Plan; the former SDI wage ceiling was removed effective January 1, 2024.
For a worker below the Social Security wage base whose pay is fully subject to all three taxes, 6.2% + 1.45% + 1.3% = 8.95% before federal or California income-tax withholding.
Variable income-tax withholding
Federal income-tax withholding and California PIT are different. They are not simple flat percentages of gross pay. Payroll uses withholding methods that account for the payroll period and information you supplied to your employer.
• Federal withholding is calculated under IRS withholding methods using Form W-4 information.
• California PIT withholding uses California withholding schedules and your DE 4 information.
Two employees with the same gross pay can therefore have different federal and California income-tax withholding.

Example: what is fixed on a $2,000 gross paycheck?
Suppose a normal $2,000 paycheck is fully subject to Social Security, Medicare and California State Plan SDI, and the employee is still below the Social Security wage base. Before calculating federal income tax or California PIT:
| Line | Calculation | Amount |
| Social Security | $2,000 × 6.2% | $124.00 |
| Medicare | $2,000 × 1.45% | $29.00 |
| California SDI | $2,000 × 1.3% | $26.00 |
| Fixed-rate subtotal | $179.00 |
$179 is 8.95% of the $2,000 gross paycheck. Federal income-tax withholding and California PIT would then depend on the employee’s withholding setup and taxable wage bases. Health insurance, retirement contributions, other benefits or post-tax deductions can further change net pay.
1. Federal income-tax withholding
Federal income tax is usually the most variable tax line on a paycheck. Employers use IRS withholding methods rather than simply multiplying your gross pay by your annual marginal tax bracket.
The 2026 Form W-4 can affect withholding through filing status, the multiple-jobs/spouse-works step, credits, other income, deductions and any additional amount you request per paycheck. If your W-4 changes, your federal withholding can change even when gross pay does not.
Your federal tax bracket is not the same thing as the percentage withheld from one paycheck. Withholding is a payroll prepayment mechanism; your final annual tax is determined when you file your return.
2. Social Security tax
The employee Social Security rate is 6.2% in 2026, but it does not apply forever during the year. The 2026 Social Security wage base is $184,500. Once covered wages reach that annual limit, the employee’s 6.2% Social Security withholding stops on additional covered wages for the rest of that calendar year.
Official sources: IRS Publication 15 (2026) | SSA 2026 taxable maximum
This is one reason a high earner may see take-home pay increase later in the year even when gross pay stays the same: the Social Security line can fall to zero after the annual wage base is reached.
3. Medicare and Additional Medicare withholding
Regular Medicare withholding is 1.45% of covered wages and has no annual wage cap.
There is also a 0.9% Additional Medicare Tax withholding rule. For payroll withholding, an employer must begin the extra 0.9% in the pay period when wages it has paid to an employee exceed $200,000 for the calendar year, and continue through year-end. The employer uses the $200,000 withholding threshold regardless of the employee’s filing status.
Important distinction: the filing-status thresholds used to determine your final Additional Medicare Tax liability are not the same as the employer’s $200,000 payroll-withholding trigger. Any difference is reconciled on your tax return.
4. California Personal Income Tax (PIT) withholding
California PIT is the state income-tax amount withheld from wages. It is variable, not a single fixed California paycheck percentage.
California publishes withholding schedules for employers. In 2026, EDD provides both Method A (Wage Bracket Table Method) and Method B (Exact Calculation Method). The calculation uses factors such as pay period, filing status and the employee’s DE 4 elections.
California still uses a separate state withholding certificate. New employees and workers changing withholding generally complete both the federal Form W-4 and California Form DE 4. The redesigned federal W-4 no longer uses allowances, but the California DE 4 still does.
If an employee does not provide a properly completed DE 4, EDD instructs employers to withhold California income tax as if the employee were single and claiming zero withholding allowances.

5. California State Disability Insurance (SDI)
For 2026, California’s State Plan SDI withholding rate is 1.3%. California removed the SDI taxable-wage limit effective January 1, 2024, so there is no annual State Plan SDI wage ceiling like the Social Security wage base.
SDI helps fund Disability Insurance and Paid Family Leave benefits. Some employees can have different treatment, including workers covered by an approved Voluntary Plan or categories of employment that are not subject to SDI, so the line on an actual pay stub may not always be labeled or calculated identically.

How much does California itself take from your paycheck?
If you are asking only about California state payroll deductions, separate them from the federal lines. For a typical W-2 employee, the main California amounts withheld are:
• California PIT — variable withholding based on California’s withholding method and your DE 4.
• California SDI — 1.3% in 2026 for wages subject to State Plan SDI.
Social Security, Medicare and federal income-tax withholding also reduce a California paycheck, but they are federal, not California state taxes. UI and ETT are employer contributions under California’s payroll-tax system rather than normal employee deductions.
Not everything taken from your paycheck is a tax
Your net pay can be much lower than “gross minus taxes” because benefits and other payroll deductions can also come out of the check. Common examples include retirement contributions, medical/dental/vision premiums, flexible spending accounts, union dues, garnishments and other authorized deductions.
The important point is that “pre-tax” is not one universal category. A deduction can reduce one taxable wage base while remaining subject to another tax.
Traditional 401(k): a useful example
Traditional 401(k) elective deferrals generally reduce federal income-tax withholding wages. The IRS still treats those deferrals as wages for Social Security and Medicare. California EDD likewise explains that employee salary-reduction contributions to a qualified retirement or pension plan can remain “subject wages” while not being reportable as California PIT wages.
So a traditional 401(k) contribution can reduce federal and California income-tax withholding without reducing every payroll-tax line by the same amount.
HSA: California can differ from federal treatment
Health Savings Accounts are another source of confusion. California does not conform to the federal HSA regime. That means you should not automatically assume an HSA contribution receives the same California tax treatment that it receives federally. Your payroll setup and plan type matter.

Why does the percentage taken out change from paycheck to paycheck?
A changing net paycheck does not automatically mean payroll made an error. Common reasons include:
• A bonus, commission, overtime payment or other supplemental wage changed the gross and/or withholding method.
• You changed your W-4 or California DE 4.
• A benefit election started, stopped or changed.
• Your pre-tax or post-tax deduction amount changed.
• You crossed the annual Social Security wage base.
• Your employer-paid wages crossed the $200,000 Additional Medicare withholding threshold.
• Your pay frequency, hours, taxable fringe benefits or other wage components changed.
• Payroll rounding or employer-specific benefit treatment changed a small line item.
If the paycheck includes a bonus, use the California Bonus Tax Calculator for bonus-specific withholding. If you first need to determine how many hours count as regular, overtime or double time under California rules, use the California Overtime Calculator.
How to check whether the taxes on your California pay stub look reasonable
A pay stub is easier to diagnose line by line than by looking only at the net amount. Use this order:
• 1. Confirm the gross pay and pay period. Make sure hours, rate, salary amount, bonus/overtime and pay frequency are correct.
• 2. Separate taxes from benefits and other deductions. Federal income tax, Social Security, Medicare, California PIT and SDI are not the same thing as insurance premiums, retirement contributions or garnishments.
• 3. Check the fixed-rate lines. Below the Social Security wage base, Social Security should generally be 6.2% of Social Security wages; Medicare is 1.45% of Medicare wages; State Plan SDI is 1.3% of SDI wages in 2026.
• 4. Review W-4 and DE 4 settings. Filing status, credits, allowances, deductions and extra withholding can change federal or California PIT substantially.
• 5. Compare taxable wage bases. Gross pay, federal taxable wages, Social Security wages, Medicare wages and California PIT/SDI wages can differ when benefits or retirement deductions are involved.
• 6. Use year-to-date amounts when thresholds matter. Social Security can stop after $184,500 of covered wages; Additional Medicare withholding starts after employer-paid wages exceed $200,000.
Then run the same gross pay and withholding settings through our California Paycheck Calculator. Its calculation trace and pay-stub audit are designed to show which line is creating the difference instead of returning only a net-pay number.
Why is no federal or California income tax being taken out?
It is possible to see little or no federal or California income-tax withholding on a smaller paycheck even while Social Security, Medicare or SDI are still deducted. Income-tax withholding methods include low-income thresholds, filing information, credits and other adjustments. A zero income-tax line therefore does not automatically mean that payroll failed to withhold FICA or that you will owe no tax for the year.
If you expected income-tax withholding and consistently see none, check the W-4 and DE 4 on file with payroll and compare your year-to-date withholding. For federal planning, the IRS Tax Withholding Estimator can help evaluate whether your W-4 setup is likely to meet your annual goal.
Withholding is not the same as your final tax bill
California FTB describes wage withholding as a prepayment of income tax. That distinction matters: a paycheck shows what payroll withheld now, while your federal and California tax returns determine your final annual liability after other income, credits, deductions, spouse income, estimated payments and other tax items are considered.
That is why a large refund does not necessarily mean the paycheck calculation was “wrong,” and a small paycheck withholding amount does not necessarily mean your final tax will be small. The goal of this page is to explain payroll deductions, not to estimate a tax refund.

Frequently asked questions
What percentage of a California paycheck goes to taxes?
There is no universal percentage. For a typical W-2 paycheck fully subject to Social Security, Medicare and State Plan SDI, those three fixed-rate employee taxes total 8.95% in 2026 before federal income-tax withholding and California PIT. Your all-in percentage can be lower or higher depending on income, W-4/DE 4 elections, benefits, wage thresholds and the type of pay.
Does California take 13.3% out of every paycheck?
No. California PIT withholding is not a flat 13.3% payroll deduction. Employers calculate PIT using California withholding schedules and the employee’s DE 4 information. Annual marginal tax rates and paycheck withholding are related concepts, but they are not the same calculation.
What is CASDI on my paycheck?
CASDI usually refers to California State Disability Insurance withholding. The 2026 State Plan SDI rate is 1.3% for wages subject to the program, and California no longer has an annual SDI taxable-wage ceiling.
Does a 401(k) reduce Social Security and Medicare tax?
Traditional 401(k) elective deferrals generally reduce federal income-tax withholding wages, but the IRS still treats them as wages for Social Security and Medicare. California also distinguishes qualified retirement salary reductions from PIT wages. This is why a contribution can lower some tax lines without lowering all of them.
Why is my paycheck calculator different from my real pay stub?
Common causes include different W-4 or DE 4 settings, benefits with different tax treatment, year-to-date wage thresholds, taxable fringe benefits, voluntary plans, special employment categories, bonuses, and payroll rounding. Compare the taxable wage bases and each withholding line rather than only the final net-pay number.
