Filing taxes is easier than it sounds
Here is what filing taxes actually means: once a year, by April 15, you tell the government exactly how much you earned and how much tax was already withheld from your paychecks. They compare those two numbers. If too much was withheld, you get a refund. If too little was withheld, you owe the difference. That is the entire process.
Step 1: Wait for your W-2
An employer generally must furnish Form W-2 for an employee by the current deadline, commonly January 31. Independent contractors generally receive different information forms. A W-2 reports specified wages and withholding; blank or absent boxes can be valid.
Keep this form. It is the most important document in your tax filing. If you do not receive your W-2 by mid-February, contact your employer, they are required to provide it.
W-2 vs W-4
The W-4 is what you fill out when you start a job, it tells your employer how much to withhold. The W-2 is what you receive after the year ends, it shows what was actually withheld. Filing taxes is essentially using your W-2 to reconcile whether the withholding was right.
Step 2: Choose a free filing method
For the 2026 filing season, taxpayers with adjusted gross income of $89,000 or less can use guided IRS Free File software by starting at the IRS Free File page. Partner eligibility rules vary, and the partner list can change, so use the current IRS page instead of searching for a vendor by name. Free File Fillable Forms are also available without that income ceiling for taxpayers comfortable preparing their own federal return.
Another excellent option is VITA (Volunteer Income Tax Assistance), a free IRS-certified program where trained volunteers help you file. VITA sites are often found at libraries, community centers, and universities. For a teen filing for the first time, this can be a great way to get it right without paying anything.
Step 3: Fill out your 1040
The main federal tax form is the Form 1040. It asks for:
- Your personal information and Social Security number
- Your total income (from your W-2)
- Your deductions (dependents have special standard-deduction rules, so use the current tax-year instructions)
- Your tax calculation
- How much was already withheld
Tax software can guide entry, but the filer remains responsible for including all required income and checking the completed return. A W-2 may be only one of several documents.
Refund vs owe
A tax refund is not free money, it is money you overpaid during the year. If you get a large refund, it means your employer withheld too much and you gave the government an interest-free loan. If you owe money, your withholding was too low. Adjusting your W-4 at work can balance this out.
Step 4: Check the current filing deadline
The federal individual filing deadline is usually April 15, but weekends, holidays, disaster relief, or other IRS action can change it. An extension generally gives more time to file, not more time to pay. Check the IRS deadline for the specific tax year and estimate and pay any amount due by that deadline.
A teen's filing requirement and tax liability depend on earned income, unearned income, dependency status, and other tax rules. If federal income tax was withheld but the final return shows less tax due, filing is how the worker claims the refund.
Step 5: Check your state taxes
Most states require a separate state tax return. The process is similar, you enter the same W-2 information into a state form. Free state filing is often available through the same software you used for federal.
Real-world example
Sofia receives a W-2 showing $87 of federal income tax withheld. She enters the W-2 and her dependency and other income information through IRS Free File. Her completed return shows zero federal income tax, so the $87 withholding is an overpayment and becomes her refund. The completed return—not her age or one income number—determines that result.
One more thing to know: if you earn money that is not from a regular employer, like babysitting, lawn mowing, or selling things online, this is called self-employment income and it is handled differently. You may need to file a Schedule C and pay self-employment tax. This will be covered in the side hustles lesson, but it is good to know the distinction exists.
What is a W-2 form?
You earned $5,500 this year and had $120 withheld in federal income tax. You file your return and owe zero federal income tax. What happens to the $120?
How should a first-time filer determine the federal filing deadline?
Which free resource can help a teen file taxes in person with a trained volunteer?
Finish and keep records
Review the completed return before submitting it, save the return and supporting documents securely, and keep proof of electronic filing or mailing. A teen may owe tax, receive a refund, or have no balance; age and a vague idea of “typical” income do not decide the result. File when required, and consider filing to claim a refund of overwithholding even when a return is not otherwise required.
To file federal income taxes, collect every required tax document, use the current Form 1040 instructions or an eligible filing service, and meet the current tax-year deadline. IRS Free File and VITA may provide free help. A refund occurs only when payments and refundable credits exceed the tax shown on the completed return.
