The moment that changes everything
There's a specific look teenagers get the first time they see their pay stub. They expected to see the number they calculated, hours times hourly rate, and instead they see something significantly smaller, with a list of deductions they've never heard of.
If you've already talked through this with them, they'll shrug and understand. If you haven't, it can feel like a betrayal, and worse, they may not know what to do with the money they do receive.
A first job is one of the most valuable financial education moments a teenager will ever have. It's real money, real decisions, and real consequences. Here's what to cover before they start.
Understanding the pay stub
Walk your teenager through a sample pay stub before their first paycheck arrives. It doesn't need to be yours, you can find examples online easily. The goal is to make none of it a surprise.
Gross pay vs. net pay: Gross is what they earned. Net is what they receive. The gap is where most first-time workers get confused.
Federal income tax: The employer withholds this based on the W-4 form your teenager fills out when they're hired. For most teenagers earning a modest amount, this may be minimal or zero, but it's still worth understanding. If they expect to owe no tax because their income is below the standard deduction, they can claim exemption.
FICA taxes: Social Security (6.2%) and Medicare (1.45%) come out of every paycheck for almost everyone. These are non-negotiable. Explain that Social Security is essentially a forced retirement savings system, they're paying into a pool they'll eventually draw from.
State income tax: Varies by state. Some have it, some don't. Worth knowing in advance.
The W-4 form: This determines how much federal income tax is withheld. Many teenagers fill it out incorrectly because no one explains it. For most teenagers with a single job and a simple tax situation, the standard information is correct and they can expect a refund (or owe very little) at tax time.
Filing taxes for the first time
If your teenager earns income, they may need to file a federal tax return. The threshold changes slightly each year, but for 2026 a single dependent generally needs to file if their earned income exceeds $14,600.
Even if they don't have to file, they should if taxes were withheld, because they'll likely get a refund. That refund is their own money that was over-withheld.
Filing taxes for the first time is a great exercise to do together. Free tools like IRS Free File handle straightforward returns easily. The goal isn't for them to be a tax expert, it's for them to understand the process and not be afraid of it.
What to do with the money
This is where most parents drop the ball. They're happy their teenager is working and earning, but the conversation about what to actually do with the money never happens.
Here's a simple framework to give them:
The allocation rule: 50% for spending (things they want, going out, clothes), 30% for saving toward a near-term goal (a car, a laptop, a trip), 20% for long-term savings (emergency fund or future investing). The exact percentages matter less than the habit of allocating before spending.
Open a separate savings account: Most teenagers only have a checking account tied to their debit card. Help them open a savings account at the same bank, set up an automatic transfer for whatever amount they've decided to save, and leave it alone.
Spend intentionally, not by default: The biggest financial mistake new earners make is spending whatever's left after expenses, rather than saving first and spending what's left. This is the difference between building wealth and staying broke at any income level.
The first job is also a negotiation lesson
Most teenager jobs have set wages, but not always. And more importantly, the habits they form in their first job, showing up early, asking for more responsibility, understanding the difference between the wage listed and what they actually take home, carry into their entire career.
Teach them to track their hours independently, not just trust that the paycheck is right. Errors happen. An employee who understands their own pay is more likely to catch them.
Tax-advantaged accounts they can access early
If your teenager earns income from wages or self-employment, they're eligible to contribute to a Roth IRA. This is one of the most powerful financial moves available.
A Roth IRA is funded with after-tax money, and growth is completely tax-free. Money contributed at 16 has decades to compound before it can be withdrawn in retirement. Even $500 contributed at 16 grows substantially by age 65.
Some families match their teenager's contributions to make saving feel more achievable. "Every dollar you save, I'll match 50 cents" creates both an incentive and a lasting habit.
The contribution limit for 2026 is the lesser of their earned income or $7,000 per year.
Making it real, not a lecture
The best time to have this conversation is before the first job starts, ideally when they're job hunting, or when they've just been offered something. Not as a lecture, but as "let me show you what's about to happen."
Pull up an online paycheck calculator and show them what $15/hour, 20 hours a week looks like after taxes in your state. Let them react. Let them ask questions. Then talk through what you'd do with that money if you were starting over.
The first paycheck moment should be one of excitement and clarity, not confusion and disappointment.
