If you made under $10,000 last year, you almost certainly do not have to file a federal tax return. For tax year 2025, the lowest income threshold that triggers a filing requirement is $15,750 for a single filer under 65, and every other filing status sits higher.1Internal Revenue Service. Check if You Need to File a Tax Return Three situations override that: $400 or more in self-employment income, being claimed as someone else’s dependent with certain types of income, or receiving advance Premium Tax Credits through the ACA Marketplace. And even when you’re not required to file, filing is often worth doing, because refundable credits and withheld taxes can send a real refund your way.
The 2025 Filing Thresholds
The IRS sets a gross income threshold for each filing status. If your gross income (all non-exempt income before any deductions) is below the threshold for your status and age, you aren’t required to file. For tax year 2025 (returns due April 2026), these are the thresholds for filers under 65:1Internal Revenue Service. Check if You Need to File a Tax Return
- Single: $15,750
- Head of household: $23,625
- Married filing jointly (both under 65): $31,500
- Married filing jointly (one spouse 65 or older): $33,100
- Qualifying surviving spouse: $31,500
Filers 65 and older get higher thresholds because an additional standard deduction amount applies. A single filer 65 or older isn’t required to file unless gross income reaches $17,550. For a head of household 65 or older the figure is $25,625, and for a married couple filing jointly where both spouses are 65 or older it’s $34,700.1Internal Revenue Service.

Every one of those numbers is comfortably above $10,000. If your only income was wages, Social Security, pension payments, or similar, and nobody else can claim you as a dependent, you’re under the line.
One status is the outlier: married filing separately has a filing threshold of just $5.1Internal Revenue Service. Check if You Need to File a Tax Return If you use that status, you must file regardless of how little you earned.
When You Have to File Even Below $10,000
Self-Employment Income of $400 or More
This is the rule that catches the most low-income filers. If you had net earnings of $400 or more from self-employment, you must file a return no matter how small your total income was.2Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) That covers freelance work, independent contracting, rideshare driving, selling on online platforms, and any other work where no employer is withholding taxes for you.
The reason the floor is so low: self-employed workers owe self-employment tax at 15.3% to cover both the employee and employer shares of Social Security and Medicare. You report the business income on Schedule C and calculate the tax on Schedule SE.2Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
One thing to keep in mind: third-party payment platforms like Venmo, PayPal, and online marketplaces are only required to send a Form 1099-K when your payments for goods or services exceed $20,000 and 200 transactions in a year.3Internal Revenue Service. IRS Issues FAQs on Form 1099-K Threshold Under the One, Big, Beautiful Bill, Dollar Limit Reverts to $20,000 Not getting a 1099-K doesn’t eliminate your obligation to report self-employment income. If you earned $400 or more net, you file.
You Can Be Claimed as a Dependent
If someone else can claim you as a dependent (a parent, usually), a separate and lower set of filing rules applies. For tax year 2025, a single dependent under 65 must file if any of the following are true:4Internal Revenue Service. Publication 501 (2025), Dependents, Standard Deduction, and Filing Information
- Unearned income over $1,350 (interest, dividends, capital gains, and similar investment income)
- Earned income over $15,750 (wages, salaries, and tips)
- Gross income exceeding the larger of $1,350, or earned income (up to $15,300) plus $450
The unearned income threshold is the one most likely to surprise people. A teenager with a custodial investment account producing more than $1,350 in dividends has to file even with no job at all. That investment income may also be taxed at the parent’s higher rate under the kiddie tax rules, though in some cases the parent can report the child’s investment income on their own return instead.4Internal Revenue Service. Publication 501 (2025), Dependents, Standard Deduction, and Filing Information
You Received Advance Premium Tax Credits
If you bought health insurance through the ACA Marketplace and got advance payments of the Premium Tax Credit to reduce your monthly premiums, you have to file a return to reconcile those advance payments, even if your income is below the normal filing threshold.5Internal Revenue Service. The Premium Tax Credit – The Basics Skipping that reconciliation can block you from receiving the credit in future years.
Why Filing Anyway Usually Pays
Required or not, filing is often the smartest move for someone who earned under $10,000. The real question isn’t whether the law makes you file; it’s how much money you leave behind by not filing.
Getting Back Any Tax That Was Withheld
If you worked a W-2 job and your employer withheld federal income tax from your paychecks, filing a return is the only way to get that money back. At income under $10,000, your actual federal income tax is almost certainly zero, so every dollar of withholding comes back as a refund. Check Box 2 of your W-2 to see what was withheld.
The Earned Income Tax Credit
The EITC is the single biggest reason low-income workers should file. It’s refundable, meaning it pays out even if you owe nothing. The amount depends on your income, filing status, and number of qualifying children. Maximum credits for tax year 2025:6Internal Revenue Service. Earned Income and Earned Income Tax Credit (EITC) Tables
- No qualifying children: $649
- One qualifying child: $4,328
- Two qualifying children: $7,152
- Three or more qualifying children: $8,046
You claim the EITC by filing Form 1040 and, if you have qualifying children, attaching Schedule EIC.7Internal Revenue Service. How to Claim the Earned Income Tax Credit (EITC) The IRS will not send it to you automatically. No return, no credit.
The Additional Child Tax Credit
The Child Tax Credit normally reduces a tax bill, but the refundable portion, called the Additional Child Tax Credit, can generate a refund even if you owe no income tax. Eligible taxpayers can receive up to $1,700 per qualifying child, provided they have at least $2,500 in earned income.8Internal Revenue Service. Child Tax Credit You claim it on Schedule 8812 filed with your Form 1040.
Combined with the EITC, a working parent earning under $10,000 with two children could receive a refund of more than $10,000 in credits alone. That’s the money that disappears if you assume you don’t need to file.
Your Social Security Earnings Record
Filing also creates a record of your earnings with the Social Security Administration, which uses your earnings history to calculate future retirement benefits.9Social Security Administration. Review Record of Earnings For self-employed workers especially, filing is how those earnings get recorded at all.
You Have Three Years to Claim a Refund
There’s no penalty for filing late when you’re owed a refund and had no filing requirement. But the window isn’t open forever. The IRS generally gives you three years from the original due date of the return to claim a refund. After that, the money stays with the Treasury.10Internal Revenue Service. Time You Can Claim a Credit or Refund
So if you earned $8,000 in a prior year and had taxes withheld but never filed, you can still go back and claim that refund along with any credits you qualified for. Once three years pass from the April due date, it’s gone. If you skipped filing in a recent year and had earned income, it’s worth going back now.
State Returns Follow Different Rules
Federal thresholds don’t control what your state requires. Most states that have an income tax set their own filing thresholds, and some are considerably lower than the federal ones. A handful require a return from anyone with just a few thousand dollars in income. Several states have no income tax at all. If yours does, being clear at the federal level doesn’t automatically mean you’re clear at the state level. Check your state’s rules separately.
Free Ways to File
At income under $10,000, you qualify for every free filing option out there, so there’s no reason to pay anyone to prepare a return this simple.
IRS Free File offers free tax preparation software to taxpayers with adjusted gross income of $89,000 or less, through a partnership between the IRS and private software companies. You access it through the IRS website.11Internal Revenue Service. E-file: Do Your Taxes for Free Each partner sets its own eligibility details, so if one doesn’t fit your situation, try another.
For in-person help, the IRS sponsors two volunteer programs. Volunteer Income Tax Assistance (VITA) provides free preparation for people who generally earn $69,000 or less, people with disabilities, and taxpayers with limited English.12Internal Revenue Service. Free Tax Return Preparation for Qualifying Taxpayers Tax Counseling for the Elderly (TCE) focuses on taxpayers age 60 and older. Both use IRS-certified volunteers who handle the straightforward returns low-income filers typically need. The IRS website has a locator tool for nearby sites.
Returns at this income level are usually a Form 1040, possibly Schedule EIC if you’re claiming the Earned Income Tax Credit with qualifying children, and Schedule 8812 if you’re claiming the Additional Child Tax Credit. With free software or a volunteer preparer, the whole thing can take under an hour.
