The basics
What taxes actually are and why they exist.

Taxes are money the government collects from people who earn income to pay for things everyone uses — roads, schools, emergency services, healthcare programs, the military, and a lot of other things you can debate the value of.

In the US, the federal government taxes your income, and so does your state (in most states). The amount you owe depends on how much you earned and what tax bracket that puts you in.

Here's the part that trips people up: tax brackets are marginal, not flat. If you earn $50,000, you don't pay 22% on all of it. You pay a lower rate on the first chunk, a slightly higher rate on the next chunk, and so on. Most people pay a lower effective tax rate than their bracket suggests.

The tax year runs January 1 through December 31. You file your return by April 15 of the following year, reporting what you earned and calculating whether you owe more or get a refund.

Why your paycheck is smaller than expected
When you start a job, your employer withholds taxes from every paycheck and sends them to the government on your behalf. Federal income tax, state income tax, Social Security (6.2%), and Medicare (1.45%) all come out before you see the money. This is normal and expected.
Know the documents
W-2, 1099, W-4 — what each one actually means.

These forms sound intimidating. They're not. Here's each one in plain English.

W-2
Your employer sends this to you by January 31st. It shows how much you earned and how much tax was already withheld. You need this to file your return.
1099
You get this instead of a W-2 if you're a freelancer, contractor, or did gig work. No taxes were withheld — you owe them yourself. This surprises a lot of people.
W-4
The form you fill out when you start a job. It tells your employer how much to withhold from each paycheck. Most people just select "Standard" and move on.
1040
The main federal tax return form you file each year. Most people use software that fills this out for them — you just answer questions and it does the math.
Refund
If more was withheld from your paychecks than you actually owe, the government sends the difference back. A big refund means you over-withheld all year — it's not a bonus.
Deduction
An expense that reduces your taxable income. Student loan interest, some education costs, and charitable donations can all be deductions. Fewer people itemize these now since the standard deduction is high.
Step by step
How to actually file your taxes.

For most young people with a straightforward income situation, filing takes less than an hour. Here's the process.

1
Gather your documents
Wait until after January 31st — that's when W-2s and 1099s are due. You'll also need your Social Security number and last year's return if you have one. Bank account info for your refund deposit.
2
Pick your filing method
If you earned under $79,000, you can file for free through IRS Free File. TurboTax, H&R Block, and FreeTaxUSA also have free tiers for simple returns. For your first few years, one of these tools is all you need.
3
Answer the questions
Modern tax software walks you through everything. You enter numbers from your W-2, answer questions about your situation, and it calculates what you owe or what you're getting back. Most simple returns take 20–40 minutes.
4
Review and submit
Check the numbers once before you file. Make sure your name, SSN, and bank info are correct. E-filing is faster and more reliable than mailing. You'll get a confirmation and your refund (if any) within a few weeks.
5
Save your return
Download a PDF of your completed return and keep it somewhere safe. You'll need last year's numbers when filing next year, and sometimes for things like loan applications or financial aid verification.
The deadline
Federal taxes are due April 15th. If you need more time, you can file for a free extension to October 15th — but that only extends the filing deadline, not the payment deadline. If you owe money, you still need to estimate and pay by April 15th or you'll get charged interest.
Common situations
Things that trip first-timers up.

These are the scenarios that cause the most confusion. Click to get the actual answer.

I had a side job or freelance income. Do I have to report it? +
Yes. All income is taxable, including cash payments, Venmo for services, selling things online, and gig work. If you made more than $400 from self-employment, you owe self-employment tax on top of regular income tax. This catches a lot of people off guard the first time.
I'm a student. Do I even have to file? +
If you earned more than the standard deduction ($14,600 for 2024) from a job, you're required to file. Even below that threshold, you should file if taxes were withheld from your paycheck — you'll likely get a refund. Scholarships used for tuition are generally not taxable; scholarships used for room and board often are.
My parents claimed me as a dependent. Does that change things? +
Yes. If your parents claim you as a dependent, you can't claim yourself on your own return. Your standard deduction is calculated differently and there are limits on certain credits. Tax software will ask you this question and adjust accordingly — just answer honestly.
What actually happens if I just... don't file? +
The IRS notices. They send letters. Then more letters. Then they calculate what they think you owe (usually unfavorably for you) and bill you, with penalties and interest added. The penalty for not filing is worse than the penalty for filing and not paying. File even if you can't pay the full amount — then set up a payment plan.
