The income threshold that triggers a filing requirement depends on your age, filing status, and type of income
The IRS sets a minimum income level each year — called the standard deduction — below which you do not have to file a federal tax return. If your total income falls below this threshold, filing is optional. However, the threshold varies significantly based on whether you are single, married, a dependent, self-employed, or over 65. The standard deduction also changes annually, so the number that applied last year may not explore this year.
Your filing requirement also depends on the type of income you earned. Wages from an employer count differently than self-employment income, investment income, or rental income. If you had taxes withheld from your paychecks, you may want to file even if you are below the threshold, because filing is the only way to recover that money as a refund.
Key Takeaways
- The standard deduction threshold changes every year and varies by age and filing status; for 2024, a single person under 65 with only wages does not have to file unless income exceeds $14,600.
- If you are self-employed and earned $400 or more in net profit, you must file regardless of your total income.
- If your employer withheld federal income tax from your paychecks, you should file to recover that money as a refund, even if you are below the threshold.
- Dependents have a lower threshold than independent filers, and the calculation is more complex if you have unearned income like interest or dividends.
- The threshold for married couples filing jointly is roughly double the threshold for single filers, but only if both spouses meet the age requirement.
Standard deduction thresholds by filing status and age
The standard deduction is the amount of income the IRS does not tax. For 2024, the threshold is $14,600 for a single person under 65 with only wage income. For a married couple filing jointly where both spouses are under 65, the threshold is $29,200. These numbers increase if you are 65 or older — an additional $1,850 for single filers and $1,500 per spouse for married couples filing jointly.
If you are the head of a household (usually a single parent supporting dependents), your 2024 threshold is $21,900. If you are married but filing separately, your threshold is $14,600 — the same as a single filer. These thresholds are set by Congress and change most years, usually by a small amount tied to inflation.
To find the current year's threshold, check the IRS website or your tax software, because using last year's number could lead you to file late or miss a refund. The threshold for the year you are filing is what matters, not the year the income was earned.
Self-employment income has its own filing requirement
If you earned money from self-employment — including freelance work, gig economy jobs, rental income, or a side business — the filing rule is different. You must file a federal tax return if your net self-employment income (income minus business expenses) is $400 or more, regardless of your age or filing status. This applies even if your total income is well below the standard deduction.
Self-employment income also requires you to pay self-employment tax, which covers Social Security and Medicare. Filing is how you report and pay this tax. If you earned less than $400 in net self-employment income, filing is optional, but you may still choose to file if you had taxes withheld or want to claim refundable credits.
Keep records of all business expenses — supplies, equipment, mileage, home office costs — because these reduce your net income and may lower your filing requirement. A Schedule C form (Profit or Loss from Business) is where you report this income and calculate the net amount.
Dependents and unearned income lower the threshold
If you are claimed as a dependent on someone else's tax return, your filing threshold is lower. For 2024, a dependent with only wage income must file if their income exceeds $14,600 — the same as an independent single filer. However, if you have unearned income (interest, dividends, capital gains, or other investment income), the threshold drops to $1,300. If you have both wages and unearned income, the calculation is more complex and depends on the total of each type.
A dependent with $500 in interest income and $10,000 in wages, for example, would need to file because the unearned income portion triggers a requirement. The IRS Form 1040 instructions include a worksheet to calculate whether a dependent must file when income is mixed.
If you are unsure whether you are claimed as a dependent, ask the person supporting you or check last year's return. Being claimed as a dependent affects not only your filing requirement but also your ability to claim your own standard deduction and certain credits.
Withheld taxes and refundable credits may require you to file below the threshold
Even if your income is below the filing threshold, you should file if your employer withheld federal income tax from your paychecks. The only way to recover that money is to file a return and claim a refund. If you earned $12,000 and had $1,500 withheld, filing gets you that $1,500 back — filing is optional, but not filing costs you money.
You should also file if you are may have access to to refundable credits, which are credits that can result in a refund even if you owe no tax. The Earned Income Tax Credit (EITC) and the Additional Child Tax Credit are the most common refundable credits. These credits can be worth hundreds or thousands of dollars, and you only receive them by filing.
Check your pay stubs to see how much was withheld. If the amount is significant relative to your income, filing is almost certainly worth your time. Tax software and the IRS Free File program can help you file at no cost if your income is below a certain threshold.
What happens if you do not file when you should have
If you owed taxes and did not file, the IRS will eventually contact you. The penalty for not filing is usually 5 percent of the unpaid tax per month, up to 25 percent total. If you owed no tax but straightforward did not file, there is no penalty — but you also lose the chance to claim a refund. The IRS keeps unclaimed refunds for three years; after that, the money goes to the U.S. Treasury.
If you filed late but owed no tax, there is no penalty. If you filed late and owed tax, penalties and interest accrue from the original due date. Filing as soon as you can, even years late, stops additional penalties from accumulating and may recover a refund if you are still within the three-year window.
How to determine your filing requirement step by step
Step 1: Determine your filing status (single, married filing jointly, head of household, etc.) and whether you are 65 or older.
Step 2: Find the 2024 standard deduction for your status and age on the IRS website or in your tax software.
Step 3: Add up all your income for the year: wages (from W-2 forms), self-employment income, interest, dividends, rental income, and any other sources.
Step 4: If you are self-employed, calculate your net self-employment income (income minus business expenses). If it is $400 or more, you must file.
Step 5: If you are a dependent, check whether you have unearned income. If you do, use the dependent worksheet in the Form 1040 instructions.
Step 6: Compare your total income to the standard deduction for your status. If income is below the threshold and you have no self-employment income of $400 or more, filing is optional — but check whether you had taxes withheld or are may have access to to credits.
Frequently Asked Questions
Do I have to file if I made less than $12,000 but had taxes withheld?
No, you do not have to file, but you should. Filing is the only way to recover the withheld taxes as a refund. If $1,000 was withheld from your paychecks, filing gets you that money back. The filing threshold is a minimum, not a rule that prevents you from filing below it.
What if I am a dependent with a part-time job and some investment income?
You need to add both types of income together and compare to the dependent threshold. If you earned $10,000 in wages and $500 in interest, you likely must file because the unearned income portion triggers a requirement. Use the worksheet in Form 1040 instructions to calculate your exact threshold.
Does the filing threshold change every year?
Yes. Congress adjusts the standard deduction annually, usually by a small percentage tied to inflation. Always check the current year's threshold before deciding whether to file. Last year's number may not explore this year.
If I am self-employed and earned $350 in net profit, do I have to file?
No. The self-employment filing requirement is $400 or more in net profit. If you earned $350, filing is optional. However, if you had taxes withheld from other income or are may have access to to credits, you may still want to file.
What if I earned income but am not sure what my filing status is?
Your filing status is determined by your marital status on December 31 of the tax year. If you were married on that date, you can file jointly or separately. If you were single, you file as single unless you are supporting dependents (head of household). Check the IRS website or ask a tax professional if you are unsure.
