Your First Job: Money Things Nobody Told You
Plain-English guide to your first paycheck: taxes, the W-4, paystubs, direct deposit, tips, and what to actually do with the money you earn.
Your first job is a big deal. You earn your own money, you meet new people, and you start to figure out what work feels like. But there are a few money things that nobody really tells you on day one. Let's walk through them, in plain English, before your first paycheck shows up.
A paycheck is the money your job pays you for the hours you work. It can land in your bank account or come as a paper check. Either way, the number you see is almost always smaller than what you expected — and that's the first surprise.
Why your paycheck is smaller than you thought
When you got hired, someone told you a number. Maybe $15 an hour. If you worked 10 hours, you might think you'll get $150. But you won't. You'll get less. Here's why.
Your boss takes out taxes before they pay you. Taxes are money the government collects to pay for things like roads, schools, and parks. The main ones taken from your paycheck are:
- Federal income tax — money for the U.S. government
- State income tax — money for your state (some states don't have one)
- Social Security and Medicare — money that helps older people and people who can't work
These together are sometimes called withholding — the money your boss "withholds," or holds back, before paying you. The IRS guide for students with summer jobs walks through this in plain English.
The W-4 form: what it is, why it matters
Before your first day, you'll fill out a paper called a W-4. It tells your boss how much tax to take out. If you fill it out wrong, you might get a smaller paycheck than you should — or you might owe money to the government later. If you're not sure how to fill it out, ask the person who hired you, or ask a parent.
Your first paystub
A paystub is the little paper or PDF that comes with your paycheck. It shows:
- Gross pay — the full amount you earned (for example, $150)
- Deductions — what was taken out (taxes, sometimes other things)
- Net pay — what you actually get (for example, $128)
Read it. Save it. If something looks weird, ask your manager. Mistakes happen, and you have every right to ask.
Getting paid: direct deposit vs. paper check
Direct deposit means your money lands straight in your bank account on payday. It's faster, safer, and you don't have to drive to a bank to cash a check. If you don't have a bank account yet, check out our guide on your first bank account.
If you get a paper check, you can cash it at your bank or by using a check-cashing app. Be careful with stores that cash checks for a fee — sometimes the fee is huge.
Tips, if you get them
If you wait tables, deliver food, or do hair, you might earn tips. Tips are still income. The IRS expects you to report tips you earn, even cash ones. Your boss will help you track this on your paystub.
What to do with your first paycheck
You don't have to have a perfect plan. But a simple one works well:
- Save a chunk first. Even $10 from each check builds a habit. See our saving goals page for ideas.
- Pay anything you owe. Phone bill, gas money, lunch you borrowed — handle that next.
- Spend the rest on what you actually want. No guilt. You earned it.
If you want a deeper plan, peek at our basic budget guide. The idea is simple: tell your money where to go, instead of wondering where it went.
Things nobody warns you about
- Your first day might feel awful. That's normal. Most people get faster and more comfortable in a few weeks.
- You can quit a bad job. If a workplace is unsafe or you're being treated badly, you can leave. The Department of Labor has rules about how teens must be treated at work.
- You're allowed to ask questions. "How do I clock in?" "When do I get paid?" "What's the dress code?" Asking these makes you look prepared, not clueless.
- Don't lend coworkers money. Just don't. It rarely ends well.

Common questions
Why is my paycheck smaller than I expected?
Your employer takes out taxes before paying you. Federal income tax, state income tax (in most states), and Social Security plus Medicare all come out of your gross pay. The amount left is your net pay. The IRS student tips page explains this.
What is a W-4?
A W-4 is the form you fill out for your employer that tells them how much federal tax to withhold from your pay. If you are unsure how to fill it out, ask the person who hired you or a parent.
Do teens have to file taxes?
Sometimes yes, sometimes no. It depends on how much you earned. The IRS sets a yearly threshold and updates it. The IRS Tips for Students page is the simplest place to check.
What hours can I legally work as a teen?
There are federal rules and state rules about how many hours and what kind of jobs people under 18 can do. The Department of Labor youth rules page is the authoritative source.
Should I save part of my paycheck?
Yes, even a small amount. Saving $10 or $20 from each check builds the habit. Try our saving goals page for ideas on what to save toward.
