Do I Have to File a Tax Return If I Only Made a Little Money?
Published October 29, 2026
Short answer: you may not have to file, but the answer depends on your filing status, your age, your gross income, and whether you had any self-employment income. Even when you're under the line, filing can still be worth it if federal tax was withheld from your pay.
What is the filing threshold?
The IRS publishes these amounts in Publication 501, Dependents, Standard Deduction, and Filing Information. In the 2025 edition of the publication, a single filer under 65 must file once gross income reaches $15,750. A head of household under 65 has a line of $23,625, and married filing jointly with both spouses under 65 has a line of $31,500. These lines are built on the standard deduction for each status. For tax year 2026, the standard deduction for a single filer is $16,100 under Revenue Procedure 2025-32, so check the 2026 edition of Publication 501 for the exact filing line when you prepare your return.
Gross income means money, goods, and services that aren't exempt from tax, including income from outside the United States. For a business, the IRS uses the business income figure on Schedule C, line 7, and it doesn't let you subtract a business loss first.
Does self-employment income change the answer?
Yes, and this is the part people miss. Publication 334, Tax Guide for Small Business (2025 edition), says you have to file if your net earnings from self-employment were $400 or more, even if your total income is small. Net earnings are your business profit after ordinary expenses. A side business that clears $400 can require a return even when your wages are low.
When should I file even if I'm not required to?
Publication 501 says you should file if any of the first four items below apply. The fifth is a separate rule that means you must file. Use this quick check:
- Was federal income tax withheld from your pay?
- Did you make estimated tax payments, or apply last year's overpayment to this year?
- Do you qualify for the earned income credit or the additional child tax credit?
- Is box 1e on a Form 1099-B (or box 1g on a Form 1099-DA) blank?
- Did your net self-employment profit reach $400?
If you answered yes to any of the first four, filing is usually the way to claim money back or avoid an IRS notice. A yes on the last one means you must file.
What does a worked example look like?
Illustration only, with made-up round numbers: Sam is 27 and single. In tax year 2026, Sam earns $9,000 in W-2 wages, has $350 of federal income tax withheld, and clears $600 of profit from selling handmade goods online.
Step 1: Sam's gross income from wages and the business is $9,600. That's below the 2026 standard deduction of $16,100, so the wage test alone doesn't require a return.
Step 2: Sam's $600 of net self-employment earnings is above the $400 line. Sam must file, using Schedule C and Schedule SE with Form 1040.
Step 3: The $350 of withholding is part of the same return. Whether any of it comes back depends on the full calculation. Without the side business, Sam would have no filing requirement, but filing could still be how that withheld money returns.
What is the most common mistake?
Assuming a small side income doesn't count. The $400 net-earnings rule applies whether or not a client sent you a form. Another frequent error is adding up the W-2 and forgetting a Form 1099 from a second source, which can put the total on the wrong side of the line.
What should I do next?
Pull every income document you have: W-2s, 1099s, and a list of any payment-app or cash income. Add up your gross income, check the Publication 501 table for your filing status and age, then figure your net self-employment profit separately. If the answer is still unclear, a credentialed tax preparer can walk through the numbers with you.
