California Paycheck Calculator (2026)

How It Works

California takes more lines out of a paycheck than almost any other state. Alongside the federal stack — federal withholding, Social Security and Medicare — a California paycheck carries state income tax under a nine-bracket schedule and a separate State Disability Insurance (SDI) deduction. This calculator works through all of them from your gross pay per period: it annualizes your pay, figures each tax for the year, then spreads it back across your paychecks.

The state income tax is the complicated line. California taxes income at nine marginal rates, from 1% on the first dollars to 12.3% at the top, and each rate touches only the income inside its own bracket — moving into a higher bracket never raises the tax on the income below it. Before the brackets apply, a single filer subtracts the California standard deduction of $5,900 for 2026 — far smaller than the $16,100 federal standard deduction, which is one reason California tax bites earlier than federal tax. The bracket thresholds are indexed to California inflation every year; for 2026 the Franchise Tax Board raised them 3.4%, so the 9.3% bracket — the one most middle-income Californians land in — now starts above $75,197 of taxable income. Taxable income above $1 million pays an extra 1% Behavioral Health Services Tax, bringing the top combined rate to 13.3%.

SDI is the line people notice least and understand least. It is a State Disability Insurance withholding of 1.3% of all wages in 2026, set by the Employment Development Department, and it funds both short-term disability benefits and California Paid Family Leave. It is paid entirely by employees — the employer contributes nothing and only collects it. Since January 1, 2024 there has been no wage cap on SDI, so unlike Social Security it keeps taking 1.3% of every dollar no matter how high your salary goes. On a $65,000 salary that is $845 a year; on $200,000 it is $2,600.

The federal lines follow the same rules as everywhere else: Social Security at 6.2% of wages up to the $184,500 wage base for 2026, Medicare at 1.45% of all wages, plus an additional 0.9% Medicare tax on wages above $200,000 for a single filer. Federal income tax withholding is the one line this calculator does not estimate — it depends on your W-4, so you enter it from your pay stub, and the calculator builds the rest around it.

Worked Example

A single filer earning $2,500 every two weeks — $65,000 a year — with $280 of federal withholding per paycheck. California taxable income is $65,000 minus the $5,900 standard deduction = $59,100. The bracket math: 1% of the first $11,456 is $114.56; 2% of the next $15,701 is $314.02; 4% of the next $15,704 is $628.16; and 6% of the remaining $16,239 is $974.34 — a total of $2,031.08 for the year, or $78.12 per paycheck. SDI is 1.3% of $65,000 = $845 a year, or $32.50 per paycheck. FICA is $4,972.50 a year: Social Security 6.2% of $65,000 = $4,030, plus Medicare 1.45% of $65,000 = $942.50. Total deductions are $581.87 per paycheck ($280 federal + $191.25 FICA + $78.12 state tax + $32.50 SDI), leaving net pay of $1,918.13 every two weeks — $49,871.38 a year, or 76.7% of gross pay.

How the numbers move at other pay levels, bi-weekly, with federal withholding held at $280 per paycheck and no other deductions:

The state tax line grows much faster than pay because the brackets are progressive: moving from $1,500 to $3,500 per paycheck (about 2.3 times the gross) lifts California income tax from $666.30 to $4,231.86 — more than six times as much. SDI, by contrast, is exactly proportional: it doubles when pay doubles, because the flat 1.3% has no brackets and no cap. One caution about the table: federal withholding is held fixed at $280 in every row, which is not realistic — real federal withholding rises with income — so read it as an illustration of the state lines, not a prediction of your own paycheck.

Assumptions and What This Calculator Leaves Out

• Single filer. Married couples filing jointly use thresholds exactly double the single ones and a standard deduction of $11,800 — this calculator models single only.
• The California standard deduction ($5,900 single) is assumed. Itemized deductions are not modelled.
• California’s small personal exemption credits are not modelled, so the state tax shown runs a little high — by roughly the value of one credit.
• SDI is figured on gross wages. Pre-tax health premiums and similar cafeteria-plan deductions reduce SDI wages in reality and are not modelled.
• There is no local income tax in California — no city or county taxes wages — so no local line is needed.
• Annual tax liability is spread evenly across paychecks. Employers withhold using the EDD’s Method A (wage bracket) or Method B (exact calculation) tables, so a real paycheck can differ by a few dollars.
• Federal withholding comes from your pay stub, not from a tax table: enter the figure your employer actually withholds.
• A 401(k) and other pre-tax deductions are not modelled as tax reducers. Put them in “Other deductions” to include them in net pay — the calculator subtracts them from take-home but leaves every tax line untouched.

How to Use This Calculator

Enter gross pay per period and pay frequency, then federal withholding per period from your most recent pay stub and any other fixed deductions. The results list every line — federal, Social Security, Medicare, California income tax and CA SDI — with total deductions, net pay per paycheck, and annual gross, state tax and net.

Tips and Practical Advice

Budget from your net pay, never from your gross. The worked example shows why: $65,000 a year sounds like $5,417 a month, but the money that actually arrives is $49,871.38 a year, or about $4,156 a month. Building a budget on the gross figure is the fastest way to overspend every month — and in California the gap is wider than in most states, because the state tax and SDI lines come on top of the federal stack.

Two California quirks are worth knowing. First, once your California taxable income passes $75,197, each extra dollar of pay is taxed at 9.3% by the state alone — so a raise that pushes you across that line feels smaller than the same raise did below it. Second, SDI has no cap, so unlike Social Security it never stops mid-year: high earners keep paying 1.3% on every December paycheck exactly as they did in January. And check your DE 4 — California’s own withholding certificate, separate from the federal W-4 — because the allowances on it decide how much state tax your employer withholds each period.
