Chapter 7 — Teen Money Mastery

Preparing for
Adulthood

Taxes, first jobs, first apartments — the stuff life expects you to already know.

Nobody hands you a manual when you turn 18. This page is the closest thing to one. Work through every section — future you will be glad you did.

Tax Simulator Run The Numbers

Enter your annual income and see what taxes actually look like — plus whether you'd get a refund. Florida residents: your state tax is $0.

My Tax Estimate — W-2 Income
Annual Gross Income From job(s), before any deductions
Standard Deduction For single filers, tax year 2026
Taxable Income Gross minus standard deduction
Estimated Federal Tax Owed Based on 2026 tax brackets
Estimated Tax Withheld Federal income tax withheld (W-2, box 2)

File by April 15 every year. IRS Free File (irs.gov/freefile) is free if your income is under the limit ($89,000 for the 2026 filing season). If your parents claim you and you only have job income, you may not have to file, but file anyway if tax was withheld so you get it back. Estimates only; this isn't tax advice.
W-4 Decoder Start a New Job

Every new job starts with a W-4. It tells your employer how much to withhold. Here's what each step actually means — and what to write.

1
Personal Info

Your legal name, address, and Social Security number. Write these exactly as they appear on your Social Security card.

2
Multiple Jobs or Spouse Works?

Only complete if you have more than one job at the same time. Most teens leave this blank.

3
Claim Dependents

If your total income is under $200,000, you may qualify for credits. Most teens leave this as $0.

4
Other Adjustments

Optional. Add extra withholding here if you want more taken out each paycheck to avoid owing at tax time.

5
Sign and Date

Your signature certifies everything is accurate. Keep a copy for your records before submitting.

Job Offer Evaluator Compare Offers

The highest hourly rate isn't always the best offer. Compare two jobs across what actually matters — including benefits, schedule, and growth potential.

Conversation Corner

  • Can you walk me through our family's tax return this year — what forms did you use and what did you learn?
  • What do you wish you'd known before you signed your first lease or moved out on your own?
  • How did you evaluate your first real job offer — and would you make the same decision today?
  • What's the one adulting skill you think most people don't figure out until it's too late?
  • Can we sit down together and run through my actual financial situation — income, savings, and what I'd need to be ready to live independently?
