California law requires nine specific items on every pay stub, including total hours worked and all applicable hourly rates. Most underpayment isn't obvious theft, it's a missed shift differential, an unpaid final paycheck deadline, or hours that quietly don't add up. Check the math, not just the deposit amount.

Direct deposit makes it easy to never actually look at a pay stub. The money shows up, the number looks roughly right, and most people move on. That habit is exactly how small, recurring errors, a missed differential, a rounded-down shift, an overtime rate calculated on the wrong number, go unnoticed for months.
Here's what your pay stub is legally required to show, and what to check line by line.
What California Law Requires on Every Pay Stub
Under California Labor Code Section 226, every must show: gross wages earned, total hours worked (for non-exempt employees), the number of piece-rate units and rate if applicable, all deductions, net wages earned, the pay period dates, your name and the last four digits of your Social Security number or an employee ID, the employer's legal name and address, and all applicable hourly rates in effect and the corresponding hours worked at each rate.
Gross Pay vs. Net Pay: What Should Actually Match
Gross pay should equal your hourly rate times hours worked, plus overtime, differentials, or bonuses, before anything is subtracted. Net pay is what actually deposits, after tax withholding and any deductions like benefits. The math worth checking isn't just "did the deposit look right," it's whether gross pay matches hours worked times your rate, including the correct overtime multiplier for anything over 8 hours in a day or 40 in a week.
You worked 9 hours one day. Your stub should show 8 hours at your regular rate and 1 hour at 1.5x, not 9 hours all at the regular rate.
Every Line Item Explained, Illustrated
California's own Franchise Tax Board publishes a plain-language walkthrough of what shows up on a typical paycheck, in its Understanding Your Paycheck guide. Below is that same breakdown, illustrated against a sample stub so you can see where each number actually comes from.
Here's what each of those lines actually is, based on the state's own explanation:
Money withheld from each check and sent to the IRS toward your annual federal income tax bill. It funds programs Congress sets each year, including national defense, education, and transportation. How much is withheld depends on your earnings and the choices you made on your Form W-4.
Money set aside for the federal program that pays monthly benefits to retired and disabled workers, and to their dependents and survivors. It's withheld at a flat percentage of wages up to an annual cap set by the federal government.
Funds the federal health care program that covers older Americans and people with disabilities. Like Social Security, it's a flat percentage withheld from every paycheck, with no annual wage cap.
Pays partial wage replacement to eligible workers who can't work because of a non-work-related illness, injury, or pregnancy. Since 2004, SDI also funds Paid Family Leave, which covers workers who take time off to bond with a new child or care for a seriously ill family member.
The California counterpart to federal withholding: money sent to the state to cover your California income tax, based on your earnings and your elections. It funds state programs including education, health and welfare, and the state court system.
Beyond taxes, a stub can also show voluntary deductions like employer-sponsored health insurance premiums, life insurance, or retirement plan contributions (such as a 401(k)). These reduce net pay but, unlike tax withholding, they're elections you generally made yourself when you enrolled in benefits.
If this is your first job, or your first paycheck from a new employer, keep every stub you receive. At year end, your employer sends a Form W-2 summarizing the year's wages and withholding, and your saved stubs are the easiest way to confirm the W-2 actually matches what you were paid. If you were paid as an independent contractor instead of an employee, you won't get a W-2 at all, you'll get a Form 1099, and that income is still fully taxable even without anything withheld along the way.
Common Paycheck Errors Worth Catching Early
A few patterns show up constantly: automatic time-clock rounding that consistently rounds down rather than to the nearest interval, a shift differential or bonus that was promised but never reflected in the hourly rate used for overtime calculations, meal or rest break premiums that are owed but never paid, and misclassification as exempt from overtime when the actual job duties don't meet the legal test. None of these look like an obvious shortfall in a single check, they add up over months.
Our guide to a missing overtime paycheck walks through how to check overtime math specifically, and if you're not sure whether your role should even be receiving overtime, our misclassification and equal pay guide explains where that line is drawn.
Direct Deposit Timing, and When It's Actually Late
California requires wages to be paid at least twice a month on regular, announced paydays, with specific rules depending on your pay period and whether you're paid weekly, biweekly, or semimonthly. If your employment ends, timing gets stricter: an employee who is fired must generally be paid all wages immediately at termination, and an employee who quits with at least 72 hours' notice must be paid on their last day. A late final paycheck can trigger under Labor Code Section 203, generally your daily rate of pay for each day the wages remain unpaid, up to 30 days.
Who This Affects Most
Paycheck errors show up disproportionately in jobs with variable schedules and multiple pay rates, restaurant and hospitality workers in Fountain Valley and San Diego juggling tipped and non-tipped shifts, healthcare and caregiving staff in San Bernardino and Sacramento working shift differentials and overtime across irregular schedules, and construction and trade workers in Beverly Hills and San Francisco paid on a mix of hourly and piece-rate work. If your pay structure has more than one moving part, it's worth checking the math more than once.
And if you're comparing your current pay to what you think you should be earning, it's worth remembering that the same instinct, know your number, ask directly, applies whether you're requesting a raise or reviewing a stub. Our guide to asking for a raise covers the conversation side of that equation.
