You must file a tax return if your income exceeds the standard deduction for your filing status
The standard deduction is the amount of income the IRS lets you earn tax-free each year. If your total income is below that threshold, you generally do not have to file. If it is above, you do. The standard deduction changes every year and depends on whether you are single, married filing jointly, head of household, or another status.
For 2024, the standard deduction is $14,600 for single filers and $29,200 for married couples filing jointly, though these figures shift annually. If you earned less than your standard deduction and have no other filing requirement, you can skip filing — though you may want to file anyway if you paid taxes through withholding or are owed a refund.
Some people must file even if their income is below the standard deduction. Self-employed people, for example, must file if their net earnings from self-employment are $400 or more, regardless of total income. If you received certain types of income — like unemployment benefits or distributions from a retirement account — you may have a filing requirement even at lower income levels.
Key Takeaways
- You must file if your total income exceeds the standard deduction for your filing status, which varies by year and ranges from roughly $14,000 to $29,000 for most people.
- Self-employed people must file if their net self-employment income is $400 or more, even if total income is below the standard deduction.
- Certain types of income — such as unemployment, Social Security, or retirement distributions — can trigger a filing requirement at lower income thresholds.
- Filing when you are not required to can still be worthwhile if you paid taxes through withholding or are owed a refund.
- Your filing status (single, married, head of household) determines your standard deduction and affects whether you must file.
How filing status affects your filing requirement
Your filing status determines your standard deduction, so it directly affects whether you have to file. A single person earning $15,000 must file; a married couple filing jointly with the same combined income does not. The IRS recognizes five filing statuses: single, married filing jointly, married filing separately, head of household, and may have access to widow or widower.
Head of household status — which applies if you are unmarried and pay more than half the household expenses for yourself and a dependent — carries a higher standard deduction than single status. Married filing separately has the lowest standard deduction of all statuses, so married people who file separately are more likely to owe a return than those filing jointly.
If your filing status changed during the year — you married, divorced, or became a head of household — use the status that applies on December 31 of that tax year.
Self-employment income and the $400 rule
If you are self-employed, the filing requirement is different. You must file if your net self-employment income — what you earned minus legitimate business expenses — is $400 or more. This applies even if your total income (including a job, a spouse's income, or other sources) is well below the standard deduction.
Self-employment income includes money from freelance work, a side business, gig work, or farming. You calculate net self-employment income on Schedule C, which subtracts your business expenses from your gross income. If you had a loss instead of a profit, you generally do not have to file based on self-employment income alone, though filing may still benefit you.
The $400 threshold exists because self-employed people owe both income tax and self-employment tax (Social Security and Medicare). Even a small profit triggers self-employment tax, which is why the IRS requires filing at that level.
Special income types that require filing
Certain kinds of income force you to file even if the amount is small or your total income is below the standard deduction. If you received unemployment compensation, you must file if your total income (including the unemployment) exceeds your standard deduction. Some unemployment benefits are taxable, and the IRS requires you to report them.
Social Security benefits have their own filing rule. If you received benefits and your combined income — which includes half your Social Security plus all other income — exceeds a threshold (roughly $25,000 for single filers, $32,000 for married filing jointly), you must file. This threshold has not changed since 1984, so many Social Security recipients end up filing even at modest income levels.
Other income types with filing requirements include distributions from retirement accounts (IRAs, 401(k)s), taxable scholarships, gambling winnings, and income from rental property or investments. If you are unsure whether a particular income source requires filing, the IRS worksheet for your situation will clarify.
When you should file even if you do not have to
You are not required to file if your income is below the standard deduction and you have no other filing trigger. But filing anyway can put money back in your pocket. If your employer withheld income tax from your paychecks and you earned below the standard deduction, you overpaid and are owed a refund. You must file to claim it.
The same applies if you paid estimated taxes during the year or made tax payments when filing your previous return. If you are owed a refund, filing is the only way to get it. The IRS does not send refunds automatically.
You may also want to file to claim tax credits you are owed — such as the Earned Income Tax Credit (EITC) or the Child Tax Credit — even if you have no tax liability. These credits can result in refunds larger than the tax you paid.
Dependents and filing requirements
If you are claimed as a dependent on someone else's return, your filing requirement is different. A dependent must file if their earned income (wages from a job) exceeds $14,600 for 2024, or if their unearned income (interest, dividends, capital gains) exceeds $1,250. These thresholds are lower than the standard deduction for independent filers.
A dependent with both earned and unearned income must file if the sum of earned income plus unearned income exceeds the standard deduction or the dependent's own standard deduction, whichever is larger. The rules are complex, but the key point is that dependents — especially teenagers with part-time jobs — often have to file even at lower income levels than independent adults.
If you are unsure whether a dependent in your household must file, use the IRS Dependent Filing Requirements Worksheet, which walks through the calculation for your specific situation.
What happens if you do not file when you should
If you owe a tax return and do not file, the IRS can assess penalties and interest on any unpaid tax. The failure-to-file penalty is typically 5 percent of unpaid tax per month, up to 25 percent. If you are owed a refund and do not file, you simply do not get the money — there is no penalty, but you lose the refund after three years.
Filing late is better than not filing at all. If you realize you missed a year, you can file that return at any time. The IRS prefers to see a late return over no return. If you owe tax, filing late will result in penalties and interest, but the amount owed will be smaller than if you ignore the requirement entirely.
If you have not filed for multiple years and owe tax, consider working with a tax professional or contacting the IRS directly. The agency has programs to help people catch up on unfiled returns, and addressing it proactively is far less costly than waiting for the IRS to contact you.
Frequently Asked Questions
Do I have to file if I made less than $1,000?
Not necessarily. If your total income is below your standard deduction (roughly $14,600 for a single person in 2024) and you have no other filing requirement, you do not have to file. However, if your employer withheld taxes from your pay, filing will get you a refund.
What if I am self-employed and made less than $400?
You are not required to file based on self-employment income alone. However, if you have other income that pushes your total above the standard deduction, or if you paid taxes through withholding, you may still need to file or want to file for a refund.
Do students have to file a tax return?
Students must file if their income exceeds the standard deduction for their filing status. Dependents have a lower threshold than independent filers, so a student claimed as a dependent may have to file at a lower income level than an independent adult.
Can I file even if I do not have to?
Yes. Filing when you are not required to is often a good idea if you paid taxes through withholding, made estimated tax payments, or are owed a refund or tax credit. There is no penalty for filing when you do not have to.
What if I missed filing for a previous year?
You can file a late return at any time. If you are owed a refund, you have three years to claim it. If you owe tax, filing late will result in penalties and interest, but it is better than not filing at all.
