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. It's the number in your job offer, and the number at the very top of your pay stub.

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) 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.

A concrete example, step by step

Let's use a concrete worker: someone earning $20 an hour, 40 hours a week, single, paid every two weeks (biweekly), with a current W-4 (2020 or later) with no extra adjustments, 1 allowance on the California DE 4, and no other deductions. Here's where the money goes, using official 2026 withholding rates:

Out of $1,600 in gross pay, 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. 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, which don't take any other state payroll deductions from workers, 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 — Washington for paid leave and long-term care, and Alaska for unemployment insurance.)

A couple of things that can shrink your net pay further

The example above only includes deductions that are required by law. Many jobs also include optional, employer-based deductions that come out before you see your net pay — most commonly:

• Health insurance premiums, if your employer offers a plan and you're enrolled
• 401(k) or retirement contributions, if you signed up — or if your employer enrolled you automatically (for example, in a 401(k) or CalSavers, California's state retirement program)

These are usually voluntary — though some employers sign you up automatically unless you opt out — but if you have them, they'll make your real net pay lower than a calculation that only counts taxes. Check your own pay stub, or ask your employer's HR or payroll department, to see if either of these applies to you.
