Understanding Your Payslip: What Every 16-Year-Old With a First Job Should Know
A pay stub contains six to ten line items most teens have never been taught to read. Here's what every deduction means, why the take-home is always less than the hourly rate suggests, and how to catch payroll errors.
A 16-year-old lands their first job at $14/hour. They work 25 hours and expect a check for $350. The check says $283. “Where did $67 go?”
This is not unusual. It’s not a mistake. It’s how payroll works — and almost no school teaches it. The ability to read and verify a pay stub is a financial skill that will save money (by catching errors) and prevent anxiety (by removing the mystery) for the next 50 years of working life.
Key Takeaways
- Gross pay (hourly rate × hours worked) is always higher than net pay (what hits your bank account) — the difference is taxes and deductions.
- The mandatory deductions on every U.S. paycheck: federal income tax withholding, Social Security (6.2%), and Medicare (1.45%).
- Federal income tax withholding is based on the W-4 form the employee fills out on hire — many teens fill this in incorrectly and over-withhold.
- State income tax applies in 41 states — the rate varies from under 3% to over 9%.
- Payroll errors happen more than people realize — knowing how to read a pay stub lets you catch them.
Reading a Pay Stub: Line by Line
The Top Section: Identification
- Pay period: The dates covered (e.g., June 1-15, 2024)
- Pay date: When the check was issued
- Employee ID/name/address: Verify this is correct — wrong address means W-2 goes to wrong place
Earnings
- Regular hours: Hours worked at regular rate
- Overtime hours: Hours over 40/week (or 8/day in some states) paid at 1.5x rate
- Gross pay: Total before any deductions
Mandatory Deductions
| Deduction | Rate | What It Funds |
|---|---|---|
| Federal income tax | Varies (based on W-4) | General federal spending |
| Social Security (OASDI) | 6.2% of gross pay (up to $168,600) | Retirement and disability benefits |
| Medicare | 1.45% of gross pay (no cap) | Medicare health insurance for seniors |
| State income tax | 0-9.9% depending on state | State government programs |
| Local/city tax | Varies; 0% in most areas | City/county programs |
Voluntary Deductions (If Applicable)
- Health insurance premium
- Dental/vision insurance
- 401(k) or IRA contributions
- Transit/parking benefits
Net Pay
The amount deposited to your bank account. Gross pay minus all deductions = net pay.
The W-4 Lesson: Why Withholding Is Not Fixed
When a new employee starts a job, they fill out a W-4 form. This form tells the employer how much federal income tax to withhold from each paycheck.
Many teens fill in W-4s incorrectly because:
- They claim more allowances than they should (under-withholding = tax bill in April)
- They claim fewer than they should (over-withholding = big refund, but means the government held your money interest-free all year)
For most teens who are dependents of their parents: Checking the “someone else can claim me as a dependent” box on Step 1 of the W-4 is the most important step. This affects the withholding calculation correctly.
Catching Payroll Errors
Payroll errors happen regularly, especially with:
- New employees being set up incorrectly
- Part-time or variable-hour employees
- Employees in their first pay period
How to verify your pay stub:
- Check gross pay: Hours on time card × hourly rate = gross pay. If it doesn’t match, flag it immediately.
- Check Social Security: Should be exactly 6.2% of gross pay (unless you’ve hit the annual cap — unlikely for teens).
- Check Medicare: Should be exactly 1.45% of gross pay.
- Check for mystery deductions: Any deduction you didn’t authorize or can’t identify should be questioned.
Example catch: A 16-year-old worked 22 hours at $14/hour = $308 gross. Pay stub shows $291 gross. They check their time sheet — the employer entered 20.78 hours instead of 22. That’s $17.08 in missing wages. They flag it; it gets corrected next cycle with a true-up.
The Lifetime Financial Skill: Year-to-Date Tracking
Every pay stub shows year-to-date (YTD) totals — the cumulative amount for each line since January 1. This is how you:
- Track total earnings for the year
- Monitor total Social Security paid (to ensure accuracy)
- Calculate whether you’ll owe or get a refund when taxes are filed
- Confirm correct withholding if you update your W-4 mid-year
What to Watch For Over 3 Months
- First paycheck: Review every line together. Calculate what gross should be, check against what’s shown, calculate each mandatory deduction manually and verify it matches.
- Second paycheck: Have your teenager check it independently, then check together. Identify any deductions that changed.
- Month 3: Ask your teenager to explain each line item to you without prompting. If they can do it accurately, the lesson has landed.
Frequently Asked Questions
My teen’s first paycheck had no federal income tax withheld. Is that normal?
It depends on the W-4 they filed. If they indicated they expect to owe zero federal income tax (common for teens earning below the standard deduction), employers are instructed to withhold nothing. This is often technically correct — but they should still file in April to confirm.
What does it mean if Social Security and Medicare are listed as “FICA”?
FICA stands for Federal Insurance Contributions Act. It’s the legal name for the combined Social Security (6.2%) and Medicare (1.45%) tax. Some pay stubs list them separately; some combine them under FICA.
If my teen overpaid withholding, when do they get it back?
When they file their tax return in spring. The refund is issued by the IRS typically within 21 days of filing electronically.
