When You Don't Have to File a Federal Tax Return
You don't have to file a federal income tax return if your income falls below a certain threshold set by the IRS each year. The threshold depends on your age, filing status, and type of income. For example, a single person under 65 with only wage income typically doesn't file if they earned less than a specific amount — but that amount changes annually, so you need to check the current year's rules rather than rely on what applied last year.
Even if you're below the threshold, you might want to file anyway. If your employer withheld taxes from your paychecks, filing gets you a refund. If you had self-employment income or made estimated tax payments, filing may also work in your favor. The IRS publishes a filing requirements chart each January that shows the exact income limits for your situation.
Key Takeaways
- The IRS sets an annual income threshold below which you don't have to file, and this threshold varies by age, filing status, and income type.
- You may still want to file even if you're not required to, especially if taxes were withheld from your pay or you're owed a refund.
- Self-employed people and those with investment income have different thresholds than wage earners.
- The IRS publishes updated filing requirements each year on its website and in Publication 17.
Income Thresholds by Filing Status and Age
The IRS groups filers into categories based on whether you're single, married filing jointly, married filing separately, head of household, or may have access to widow(er). Within each category, your age matters: people 65 and older have a higher threshold because they receive an additional standard deduction.
A single person under 65 with only wages, for instance, has one threshold. A single person 65 or older has a higher one. A married couple filing jointly has a different threshold altogether. The IRS publishes these numbers in a table format on its website each tax year, usually by late December for the year ahead. You can also find them in IRS Publication 17, which is free to read.
Because these thresholds change yearly — sometimes by small amounts, sometimes more noticeably — checking the current year's rules is essential. Using last year's numbers could lead you to file when you don't need to, or to skip filing when you should.
Self-Employment Income and Special Cases
If you're self-employed, your threshold is lower than for wage earners. The IRS considers you self-employed if you had net earnings of $400 or more from self-employment during the year. If you meet that test, you must file a return even if your total income is otherwise below the filing threshold, because you owe self-employment tax (Social Security and Medicare taxes).
Other situations that require you to file regardless of income level include owing alternative minimum tax, claiming certain tax credits, or having net investment income above a specific amount. If you received a distribution from a retirement account, had rental income, or earned money from a side business, you likely need to file even if your total income seems low.
Dependents and Special Filing Rules
If someone else claims you as a dependent on their return, your filing threshold is different — usually lower. A dependent under 65 with only wage income typically has a lower threshold than an independent person of the same age. The exact amount depends on whether you have unearned income (like interest or dividends) in addition to wages.
A dependent with unearned income faces yet another threshold. For example, if you're a dependent with only interest and dividend income, you must file if that unearned income exceeds a certain amount set by the IRS each year. This rule exists because unearned income is taxed differently than wages.
When Filing Is Beneficial Even If Not Required
Many people below the filing threshold still file because they'll receive a refund. If your employer withheld federal income tax from your paychecks but you earned too little to owe tax, filing returns that withheld money to you. The same applies if you made estimated tax payments during the year.
You might also file to claim a refundable tax credit, such as the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit. These credits can result in a payment to you even if you owe no tax. Filing is the only way to receive these payments, so many people with low incomes file specifically to claim them.
How to Find Your Specific Filing Threshold
The IRS publishes filing requirements on its official website (irs.gov) each year. Look for the "Filing Requirements" page or the "Do I Need to File?" tool. You can also read IRS Publication 17, which contains detailed tables showing thresholds for every filing status and age combination.
If you're unsure whether you need to file, the safest approach is to gather your income documents (W-2s, 1099s, K-1s, and any other income statements) and compare your total to the threshold for your situation. If you're close to the line or have multiple income sources, filing is usually the safer choice — the IRS won't penalize you for filing when you weren't required to, but it may penalize you for not filing when you were.
Frequently Asked Questions
Do I have to file if I'm claimed as a dependent but earned money?
It depends on how much you earned and what type of income it was. Dependents have lower filing thresholds than independent filers. If you earned wages, your threshold is typically lower than an independent person's. If you had unearned income like interest or dividends, you face a different threshold. Check the IRS's dependent filing requirements table for your specific situation.
What if I'm self-employed and earned less than $400?
You don't have to file if your net self-employment income was less than $400. However, if you had other income (wages, interest, dividends) that pushes your total above the filing threshold for your status, you must file. Also, if taxes were withheld from other income sources, filing may get you a refund.
Can I file even if I don't have to?
Yes. Filing when you're not required to is always allowed and often beneficial. If you had taxes withheld, you'll get a refund. If you're owed a refundable credit like the EITC, filing is the only way to receive it. There's no penalty for filing when you weren't required to.
Where do I find the current year's income thresholds?
The IRS publishes filing requirements on irs.gov each year, usually by late December for the upcoming tax year. You can also read IRS Publication 17 for free, which contains detailed tables. The IRS also offers an online tool called "Do I Need to File?" that walks you through your situation.
What happens if I don't file when I'm supposed to?
The IRS may assess penalties and interest on any taxes owed. If you're owed a refund, you can't receive it without filing — and refunds typically expire after three years. If you owe self-employment tax, not filing can affect your Social Security record.
