You may not owe federal income tax if your income falls below a certain threshold, you are claimed as a dependent, or you fall into a specific category like a student or retiree with minimal earnings.
The Internal Revenue Service (IRS) sets an annual income threshold below which you do not have to file a federal tax return. That threshold depends on your age, filing status, and type of income. If your total income stays below the threshold for your situation, you have no filing requirement — even if taxes were withheld from your paychecks.
However, filing anyway can sometimes work in your favor. If your employer withheld taxes and your income was below the threshold, filing a return gets you a refund. If you received certain tax credits like the Earned Income Tax Credit, filing is the only way to claim them.
Key Takeaways
- The IRS sets different income thresholds based on age, filing status, and whether you are claimed as a dependent; for 2024, a single person under 65 with only wages does not file if income is under $14,600.
- Self-employed people have a lower threshold — generally $400 in net self-employment income — and must file even if they owe no tax.
- If you are claimed as a dependent on someone else's return, your threshold is lower and depends on whether your income is earned (wages) or unearned (interest, dividends).
- Filing a return even when not required can get you a refund of withheld taxes or allow you to claim refundable credits like the Earned Income Tax Credit.
- Thresholds change each year; the IRS publishes updated amounts in January for the prior tax year.
Income Thresholds by Filing Status and Age
The IRS publishes a table each year showing the income threshold for each filing status. For the 2024 tax year (filed in 2025), a single person under age 65 with only wage income does not file if gross income is under $14,600. A married couple filing jointly, both under 65, does not file if combined income is under $29,200. These numbers increase slightly each year for inflation.
Age matters. If you are 65 or older, your threshold is higher — $18,350 for a single filer in 2024, and $23,200 for a married couple filing jointly if both are 65 or older. If only one spouse is 65 or older, the threshold is $24,800. The IRS assumes older workers have higher medical and living expenses and gives them a larger standard deduction.
Filing status also changes the threshold. Head of household filers (usually a single parent supporting dependents) have a threshold of $19,500 for 2024. Married filing separately have much lower thresholds — generally $14,600 — and are rarely used unless there is a specific tax reason.
Self-Employment Income and the $400 Rule
If you are self-employed — a freelancer, contractor, small business owner, or gig worker — the threshold is much lower. You must file a federal tax return if your net self-employment income is $400 or more, regardless of your age or other income. This applies even if you owe no tax after deductions.
Self-employment income includes money from a side business, freelance work, or gig platforms like Uber or DoorDash. You calculate net self-employment income by subtracting business expenses from gross income. If that number reaches $400, you file. This rule exists because self-employed people owe both income tax and self-employment tax (Social Security and Medicare), and the IRS needs to track that.
If you have both W-2 wages and self-employment income, add them together against the threshold for your filing status. For example, a single person under 65 with $10,000 in W-2 wages and $5,000 in net self-employment income must file because the total ($15,000) exceeds $14,600.
Dependents and Lower Thresholds
If you are claimed as a dependent on someone else's tax return — usually a parent's — your threshold is lower. The IRS distinguishes between earned income (wages from a job) and unearned income (interest, dividends, capital gains, or distributions from investments).
For a dependent with only earned income in 2024, the threshold is $14,600 — the same as a non-dependent single filer under 65. However, if you have unearned income, the threshold drops to $1,300. If you have both types of income, you use a formula: the greater of $1,300 or earned income plus $450, up to the standard deduction for your filing status.
This matters for teenagers with part-time jobs and investment income, or young adults in college whose parents still claim them. A 19-year-old claimed as a dependent who earned $15,000 from a summer job must file. A 19-year-old claimed as a dependent who received $2,000 in interest from a savings account must file, even though the amount is small.
Special Situations: Students, Military, and Non-Citizens
Students follow the same rules as anyone else — the threshold depends on filing status, age, and income type. A full-time student claimed as a dependent has the same $1,300 unearned income threshold as any other dependent. However, students often have refundable tax credits available, so filing even when not required can result in a refund.
Military members on active duty use the same thresholds as civilians. However, military housing and food allowances are not counted as income for tax purposes, which can lower your total income below the filing threshold. Combat zone exclusions also apply — income earned in a designated combat zone may be excluded from gross income.
Non-citizens and resident aliens use the same thresholds as U.S. citizens. However, non-resident aliens have different rules and lower thresholds. If you are not a U.S. citizen, check your visa status or consult a tax professional, because the rules vary significantly by visa type.
When You Should File Even If Not Required
Filing a return when you are not required can put money back in your pocket. If your employer withheld federal income tax from your paychecks and your income was below the filing threshold, you are owed a refund. The only way to get that refund is to file a return.
You should also file if you are may have access to to a refundable tax credit. The Earned Income Tax Credit (EITC) is the most common — it can return hundreds or thousands of dollars to low-income workers and families. The Child Tax Credit and American Opportunity Tax Credit (for education expenses) are also refundable or partially refundable. These credits exist to help you, but you must file to claim them.
If you received a Form 1099 for income that was not withheld — such as freelance work, rental income, or investment income — filing creates a record with the IRS. This protects you if the person who issued the 1099 reported it to the IRS under your name.
How Thresholds Change and Where to Find Current Numbers
The IRS adjusts income thresholds each January for inflation. The numbers used for your 2024 tax return (filed in early 2025) are different from the 2023 numbers, and 2025 numbers will be released in January 2026. If you are planning ahead or checking whether you filed in prior years, use the threshold that was in effect for that specific tax year.
The IRS publishes current thresholds on its website at irs.gov, in Publication 17 (Your Federal Income Tax). You can also find them on the IRS filing status page or by calling the IRS at 1-800-829-1040. Tax software and tax preparation services also display the current threshold when you start a return.
State and local income tax rules are separate. Even if you do not owe federal tax, you may owe state or local tax. Check your state's tax authority website for state-specific thresholds.
Frequently Asked Questions
Do I have to file if I am retired and only receive Social Security?
Social Security benefits are generally not counted as income for the IRS filing threshold. However, if you have other income — pensions, interest, part-time work — add those amounts to determine if you must file. If Social Security is your only income, you typically do not file, but filing can sometimes result in a refund if taxes were withheld.
What happens if I do not file when I am supposed to?
If you owe tax and do not file, the IRS can assess penalties and interest. If you do not owe tax but are may have access to to a refund, there is no penalty — you simply lose the refund after three years. If you received a 1099 and did not file, the IRS may send you a notice if the income was reported under your name.
Can I file even if my income is below the threshold?
Yes. Filing when not required is always allowed and often beneficial. If taxes were withheld from your pay, you get a refund. If you are may have access to to tax credits, filing is the only way to claim them. There is no downside to filing when you are not required to.
Does my spouse's income count toward my filing threshold?
Only if you file jointly. If you are married and file separately, only your individual income counts toward your threshold. If you file jointly, you combine both incomes and use the married filing jointly threshold. Filing status is your choice each year.
What if I am claimed as a dependent but my parents do not actually support me?
The IRS definition of a dependent is technical and does not always match real-world support. If your parents claim you and you meet the IRS tests for being a dependent, you use the dependent threshold regardless of who actually pays your bills. If there is a dispute, the person who has the right to claim you determines your threshold.
