This guide is for educational purposes in the United States. Laws and dollar thresholds change. Always check current rules and, when needed, ask a parent or qualified tax professional for help.

What you'll learn

  • The difference between earned and unearned income, and why it matters
  • Legal ways teens can make money beyond traditional part-time jobs
  • How basic taxes work for wages vs. self-employed income
  • How to track expenses and calculate profit for small gigs
  • How teen income affects college savings and financial aid planning
  • Accounts you can use now with a parent, and what opens at age 18

Concept explanation

Money you make as a high school student falls into two big buckets: earned income and unearned income. Earned income comes from working — think hourly wages, tips, babysitting, tutoring, mowing lawns, or content creation revenue. Unearned income is money that does not come from active work, like bank interest, dividends from investments, or certain gifts.

Why does this split matter? Taxes, retirement accounts, and financial aid treat these types differently. For example, you need earned income to contribute to a Roth IRA, but you can earn interest on savings without working. Scholarships can be tax-free when used for tuition and required fees, but parts used for room and board can be taxable. Understanding the categories helps you avoid mistakes.

There are also rules about when and how teens may work. Federal and state child labor laws limit hours and types of jobs, especially during the school year and for hazardous work. Platform-based work (like selling crafts online) and freelancing (like tutoring) are allowed, but you are considered self-employed and have extra responsibilities like recordkeeping and possibly paying self-employment tax.

Finally, your money choices now connect to your future. Income you earn can help fund a 529 college savings plan or a Roth IRA for long-term growth. Building a filing system, learning to invoice, and separating savings for taxes are skills that translate directly into college life and early careers.

Why it matters

  • Planning for college and careers: A predictable side income helps you budget for application fees, campus visits, and savings. It can also become a portfolio of real experiences — from tutoring clients to a small lawn-care route — useful on college and scholarship applications.

  • Taxes and financial aid: Understanding tax basics avoids penalties and helps you keep more of what you earn. For financial aid, the way income and assets are reported can change your need-based aid eligibility. Knowing this in high school lets you plan ahead with your family.

  • Building lifelong habits: Learning to track income and expenses, set aside money for goals, and contribute to long-term accounts gives you a head start before turning 18. It is part of becoming an informed consumer and future investor.

Calculation method

Let’s walk through how to calculate money from common teen income sources and how taxes may apply.

  1. Hourly wages from a part-time job (W-2)
  • You work at a cafe 10 hours per week at $12/hour.
  • Weekly gross pay: 10 × 12=12 = 120
  • Four-week month estimate: 120×4=120 × 4 = 480
  • Your paycheck shows withholdings. Typically:
    • Federal income tax withholding: depends on your Form W-4. If your total annual income is low, withholding may be small or even zero.
    • FICA payroll taxes (Social Security and Medicare): 7.65% of wages (your employer pays another 7.65%).
  • Approximate FICA on 480:480: 480 × 0.0765 = $36.72
  • Estimated take-home for the month (ignoring federal/state withholding): 480480 − 36.72 ≈ $443.28
  1. Self-employed gigs (tutoring, lawn care, babysitting, content creation)
  • You charge $25/hour for tutoring 2 hours per week.
  • Weekly revenue: 2 × 25=25 = 50
  • Four-week month: 50×4=50 × 4 = 200 revenue
  • Track business expenses (for example, printer paper and online whiteboard subscription): $12/month
  • Net profit: revenue − expenses
Net Profit = Revenue − Deductible Expenses
  • Net profit: 200200 − 12 = $188
  • If your annual net self-employment profit is $400 or more, you generally owe self-employment tax (Social Security and Medicare for the self-employed). The full rate is typically 15.3% on most or all of net profit, with some adjustments.
Self-Employment Tax (approx.) = Net Profit × 15.3%
  • Approximate monthly self-employment tax on 188:188: 188 × 0.153 ≈ $28.76
  • Income tax may also apply depending on your total annual income and filing status. Self-employed people usually pay these taxes when filing a return; there is no employer withholding.
  1. Interest and dividends (unearned income)
  • You have $1,000 in a high-yield savings account at 4.5% annual interest.
  • One month of interest (approximate): 1,000×0.045÷121,000 × 0.045 ÷ 12 ≈ 3.75
  • Interest is unearned income; it may be taxable even if you did not work.
  1. Scholarships and grants
  • Scholarship used for qualified education expenses (tuition, required fees, books) is generally not taxable.
  • Amounts used for room, board, or optional equipment are generally taxable.
  • Example: 2,000scholarship,2,000 scholarship, 1,500 applied to tuition, $500 to dorm meal plan.
    • Tax-free: 1,500;taxable:1,500; taxable: 500.
  1. Roth IRA contribution limit for teens with earned income
Roth IRA Contribution Limit = min(Your Earned Income, IRS Annual Limit)
  • Example: You earn 2,500totalthisyear.IRSlimitexample:2,500 total this year. IRS limit example: 7,000 (subject to change). Your limit is the smaller number, so $2,500.
  • A parent can fund your custodial Roth IRA with their money, but only up to your earned income amount for the year.
Numbers like standard deductions, tax brackets, and annual contribution limits change regularly. Always check the latest figures before filing or contributing.

Case study

Meet Maya, 17, planning for college next year.

Income sources

  • Cafe job: 8 hours/week at $13/hour
  • Tutoring: 3 hours/week at $20/hour
  • Savings account: $800 at 4% APY

Step 1: Calculate monthly income

  • Cafe: 8 × 13=13 = 104/week ⇒ 104×4=104 × 4 = 416/month gross
  • FICA on cafe wages: 416×0.0765416 × 0.0765 ≈ 31.82
  • Estimated cafe take-home: 416416 − 31.82 ≈ $384.18 (ignoring other withholding)
  • Tutoring revenue: 3 × 20=20 = 60/week ⇒ 60×4=60 × 4 = 240/month
  • Tutoring expenses: $15/month (apps + supplies)
  • Tutoring net profit: 240240 − 15 = $225
  • Self-employment tax (approx.): 225×0.153225 × 0.153 ≈ 34.43
  • Tutoring after SE tax: 225225 − 34.43 ≈ $190.57
  • Monthly interest: 800×0.04÷12800 × 0.04 ÷ 12 ≈ 2.67

Step 2: Combine

  • Approximate take-home and interest: 384.18+384.18 + 190.57 + 2.672.67 ≈ 577.42/month

Step 3: Plan allocations

  • Short-term savings for application fees: $100/month
  • Emergency buffer: $50/month
  • Roth IRA: Maya’s earned income is from wages and tutoring net profit. Monthly earned income ≈ 416+416 + 225 = 641(beforepayroll/SEtax).Ifshekeepsthispacefor12months:641 (before payroll/SE tax). If she keeps this pace for 12 months: ≈ 7,692 earned income. She can contribute up to the smaller of her annual earned income or the IRS limit (subject to change). For the month, she decides to set $150 aside toward a year-end Roth IRA contribution.
  • College savings (529): 200/monthfromaparentasagift,whichstaysinaparentowned529topotentiallyreduceimpactonneedbasedaidcomparedwithstudentassets.Mayasowncontribution:200/month from a parent as a gift, which stays in a parent-owned 529 to potentially reduce impact on need-based aid compared with student assets. Maya’s own contribution: 75/month.
  • Taxes set-aside: For self-employment, Maya saves an extra 20% of net profit in a separate envelope to cover income and SE tax at year-end: 225×0.20=225 × 0.20 = 45/month.

Result: Maya builds a habit of paying herself first, preparing for taxes, and balancing near- and long-term goals.

Practical applications

  • Choosing legal income sources

    • W-2 jobs: retail, food service, lifeguarding, camp counselor. Follow hour limits during the school year; ask your school about work permits if required by your state.
    • 1099/independent gigs: tutoring, music lessons, lawn care, pet sitting, reselling, crafting, digital design commissions, content creation with platform payouts.
    • Unearned income: open a high-yield savings account to earn interest; consider a parent- or guardian-owned 529 plan for college.
  • Recordkeeping that saves you stress

    • Keep a simple spreadsheet: date, client/job, amount received, expense, category, payment method.
    • Save receipts for business expenses. Take photos and back them up.
    • For self-employment, separate money: income, taxes set-aside, and take-home.
  • Understanding forms

    • W-2: shows wages and taxes withheld from jobs.
    • 1099-NEC/1099-MISC: shows nonemployee compensation. You may not receive a form if amounts are small, but you must still report all income.
    • 1099-INT/1099-DIV: interest and dividends.
  • Taxes at a glance

    • Payroll job: employer withholds FICA; you may get a refund if too much income tax was withheld.
    • Self-employed: no automatic withholding. If your net profit is high enough, you may owe self-employment tax and income tax. Consider setting aside a portion of each payment.
  • Connecting to economics class

    • Opportunity cost: choosing a Saturday shift may mean giving up a game or social event; weigh the trade-off.
    • Marginal analysis: is an extra hour of tutoring worth the time compared with studying for exams?
    • Supply and demand: pricing your tutoring depends on how many tutors are available and how many students need help.
  • Accounts before and after you turn 18

    • Now: with a parent/guardian, you can use a custodial Roth IRA (if you have earned income), a custodial brokerage (UTMA/UGMA), and a parent-owned 529 plan for college.
    • At age 18: you can generally open your own checking, credit card (subject to issuer rules), brokerage account, and Roth IRA. You become responsible for contracts and taxes.
  • Safety and compliance

    • Check platform terms and age requirements.
    • Avoid hazardous work; follow curfews and hour limits for minors.
    • Get paid through traceable methods; avoid cash-only arrangements that make recordkeeping hard.
Build a one-page “money map”: list your income sources, planned savings percentages, and where each dollar goes (spending, savings, investing, taxes). Update it each semester.

Common misconceptions

よくある誤解
- “If I don’t get a 1099, I don’t have to report it.” All income must be reported; forms help, but they are not what make income taxable. - “Babysitting is casual, so it’s not a business.” Regular paid work is self-employment; track income and expenses and plan for taxes. - “Scholarships are always tax-free.” Only the portion used for qualified expenses like tuition and required fees is generally tax-free. - “I can’t have a Roth IRA until I’m an adult.” With earned income, a custodial Roth IRA is possible with a parent/guardian. - “Financial aid ignores student income.” Student income and assets can affect need-based aid; plan your savings location and timing with your family.

Summary

まとめ
- Earned income comes from work; unearned income includes interest and dividends. The type affects taxes and account eligibility. - W-2 jobs withhold FICA; self-employed gigs may require you to pay self-employment tax on net profit. - Track revenue and deductible expenses to calculate profit and set aside money for taxes. - You can legally earn beyond part-time jobs through tutoring, lawn care, content creation, and small online businesses. - With earned income, you can contribute to a custodial Roth IRA; families can also use 529 plans for college savings. - Laws and dollar limits change. Check current rules, especially as you approach age 18 and open accounts in your own name.
