Gross Pay vs. Net Pay in California — What's the Difference?

If you've ever compared the salary you were offered to what actually lands in your bank account, you've felt the gap between two numbers: gross pay and net pay. This guide explains both in plain language, with a concrete example, and why that gap tends to be bigger in California than in states with no income tax.

Gross pay, in one sentence

Gross pay is everything you earned before anything gets taken out. If you agreed to $20 an hour and worked 40 hours, your gross pay for that week is $800 — full stop, before taxes, before anything else. On your pay stub it's usually labeled “Gross pay” or “Total earnings.” Job offers usually state it as an hourly rate or a yearly salary: $20 an hour × 40 hours × 52 weeks is $41,600 a year gross. To compare offers, put each one into the calculator and compare the net.

At California's 2026 minimum wage of $16.90 an hour, a 40-hour week is $676 gross. Here's what the minimum wage pays after taxes — and some cities set a higher minimum (see the California minimum wage by city).

Net pay, in one sentence

Net pay is what actually lands in your bank account. It's your gross pay minus all deductions: the ones required by law (federal and state income tax, Social Security, Medicare and California SDI — State Disability Insurance, which pays part of your wages if you can't work because of illness, injury or pregnancy, or while you take paid family leave) and any you signed up for, like health insurance. Net pay is sometimes called “take-home pay,” which is a good way to think about it: it's the money you actually take home.

For a line-by-line look at each of those deductions, see how much is taken out of a California paycheck.

A real example, step by step

Let's take one specific worker: someone earning $20 an hour, 40 hours a week, single, paid every two weeks (biweekly — 26 paychecks a year), with a current W-4 (the federal tax form you fill out when you're hired, 2020 version or later) with no extra adjustments, 1 allowance on the California DE 4 (the state version of that form; each allowance lowers state withholding a little), and no other deductions. Here's where the money goes, using official 2026 withholding rates:

Two weeks at 40 hours is 80 hours × $20 = $1,600 in gross pay per paycheck. Out of that, this worker takes home $1,321.29 — about 83% of the original amount. The other 17% is federal tax, California state tax, and the two federal payroll taxes that fund Social Security and Medicare, plus California's own SDI program.

Why California takes a bigger bite than states with no income tax

Two of the five deductions above — California state tax and SDI — only exist because this worker is in California (here's what California SDI covers). Nine U.S. states don't tax wages with a state income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming.

If this same worker did the same $20/hr job in one of those states instead, there would be no California state tax or SDI line. In Texas or Florida, with no state income tax or SDI, their net pay would be $1,369.45 — about $48 more every two weeks, or roughly $1,252 more per year, from the same job at the same pay rate. (Some of those states do take their own payroll deductions from workers — Washington, for example, for paid family and medical leave.)

Pre-tax vs. after-tax deductions: why $50 doesn't cost you $50

The example above only includes deductions required by law. Many jobs add others, and when they come out makes a big difference:

• Pre-tax deductions come out before taxes are figured, so they also lower your taxes. Health insurance taken out of your paycheck — usually through what's called a cafeteria or Section 125 plan; your stub may label it “pre-tax” or “Sec 125” — lowers federal and California income tax, Social Security, Medicare and SDI. A traditional 401(k) lowers federal and California income tax, but not Social Security, Medicare or SDI.
• After-tax deductions come out after taxes, so they cost you dollar for dollar. Examples: Roth 401(k) contributions, union dues and wage garnishments (money a court or government agency orders your employer to take out, for example for child support or an unpaid debt).

Here's the same $20/hr worker with each kind of pre-tax deduction (biweekly, same W-4 and DE 4 as above):

The $50 health premium lowers net pay by only $37.33, because it also cuts every tax. The $80 401(k) contribution lowers net pay by $66.88: it cuts income tax, but Social Security, Medicare and SDI stay the same. Check your pay stub, or ask HR or payroll, to see which deductions you have and whether they're pre-tax.

Overtime works the other way: it raises your gross pay, but your net rises by less because the extra dollars are taxed too. Our California overtime pay guide shows a side-by-side paycheck, and our hourly wage after taxes table shows take-home pay at other rates.

How to check your own gross and net pay

1. Check your gross pay. Multiply your hours by your hourly rate (overtime — generally hours over 8 in a day or 40 in a week — is paid at 1.5× your rate, and hours over 12 in a day are paid at double time) and compare it with “gross pay” on your stub. If your gross pay is short, ask your employer to fix it; if they don't, you can file a wage claim with the California Labor Commissioner.
2. Check each required deduction. Social Security should be 6.2% (up to $184,500 of wages in 2026), Medicare 1.45% (plus 0.9% on wages over $200,000 a year) and SDI 1.3% — on your stub they may appear as OASDI or FICA, MED, and CA SDI. They're figured on your gross pay. If you pay for health, dental or vision insurance through work before taxes, subtract those amounts first. A 401(k) does not lower these three. Our paycheck checker can compare your stub with an estimate.
3. Ask about anything you don't recognize. If a deduction looks wrong, ask payroll or HR to explain it, ideally in writing.
4. Adjust your withholding if needed. The income tax taken from each check is an advance payment on your yearly tax. If you usually get a big refund, too much is being taken out; if you usually owe at tax time, too little is. You can change this by giving your employer a new W-4 (federal) or DE 4 (California).
