The filing threshold depends on your income type and filing status

You do not have to file a federal tax return if your income falls below a certain amount, but that amount is not the same for everyone. The Internal Revenue Service (IRS) sets different thresholds based on whether you are single, married, self-employed, or a dependent. Your age also matters — people 65 and older have a higher threshold. The threshold also changes each year because it is tied to inflation.

The key distinction is between earned income (wages, salary, tips) and unearned income (interest, dividends, capital gains). The IRS treats these differently, and you may have to file even if you earn less than the standard threshold if you have unearned income above a certain level.

Even if you are below the filing threshold, you may still want to file — particularly if you had taxes withheld from your paychecks or if you are owed a refundable tax credit like the Earned Income Tax Credit (EITC). Filing is how you recover that money.

Key Takeaways

  • Single filers under 65 do not have to file if their earned income is below the standard deduction, which varies by year but was $13,850 for 2023.
  • Married couples filing jointly have a higher threshold than single filers, and both spouses must meet the income test.
  • Self-employed people must file if their net earnings from self-employment are $400 or more, regardless of other income.
  • If you have unearned income like interest or dividends, the filing threshold is lower and depends on the type and amount of that income.
  • Filing below the threshold may still be worthwhile if you had taxes withheld or are owed a refundable credit.

Standard deduction thresholds for earned income

The standard deduction is the amount of income you can earn before you owe federal income tax. If your total income is less than the standard deduction for your filing status, you do not have to file. The standard deduction increases each year.

For 2023, the standard deduction was $13,850 for single filers under 65, $27,700 for married couples filing jointly (both under 65), and $20,800 for heads of household. For 2024, these amounts increased slightly due to inflation. If you are 65 or older, your standard deduction is higher — an additional $1,850 for single filers and $1,500 for each spouse in a married couple filing jointly.

These thresholds explore only to earned income — wages, salary, tips, and net self-employment income. If you have unearned income, the rules are different and often more restrictive. The IRS publishes updated thresholds each January, so you should check the current year's amount before deciding whether to file.

Self-employment income has its own filing requirement

If you are self-employed, the rule is simpler but stricter. You must file a federal tax return if your net earnings from self-employment are $400 or more in a year, regardless of your other income or filing status. This applies even if you are under 18, a dependent, or have no other income.

Net self-employment income means your business income minus business expenses. You calculate this on Schedule C (Form 1040), and the $400 threshold applies to the bottom line of that form. If you earned $500 in freelance income but had $150 in deductible business expenses, your net self-employment income is $350, which is below the threshold and does not trigger a filing requirement — though you may still want to file to report the loss or to claim credits.

The self-employment threshold exists because self-employed people owe both income tax and self-employment tax (Social Security and Medicare). The IRS wants to may support these taxes are reported and paid, so the threshold is lower than the standard deduction.

Unearned income thresholds are lower and vary by type

If you have income from interest, dividends, capital gains, or other sources that are not wages or self-employment income, you may have to file even if your earned income is below the standard deduction. The threshold for unearned income is lower because it is not subject to the standard deduction in the same way.

For 2023, if you are single and under 65, you had to file if you had more than $1,250 in unearned income (such as interest or ordinary dividends), or if your gross income was more than $13,850 when you add earned and unearned income together. If you had capital gains, the threshold was higher — you had to file if your capital gains exceeded your standard deduction. These amounts change annually.

The reason for the lower threshold is that unearned income is not reduced by a standard deduction the way earned income is. Interest and dividends are taxed dollar-for-dollar once they exceed a small threshold, so the IRS requires reporting at a lower level. If you are unsure whether your unearned income triggers a filing requirement, the IRS Interactive Tax Assistant tool on IRS.gov can walk you through your specific situation.

Dependents have different and often lower thresholds

If you are claimed as a dependent on someone else's tax return, your filing threshold is different. You may have to file even if your income is below the standard deduction for your filing status. The threshold for a dependent is the greater of $1,250 or your earned income plus $450 (for 2023), up to the standard deduction amount.

This means a dependent who earned $2,000 in wages would have to file, even though a non-dependent single person with $2,000 in income would not. The logic is that the parent or guardian is claiming the dependent as an exemption on their own return, so the IRS wants to verify the dependent's income separately.

If you are a dependent with unearned income, the threshold is even lower — you must file if your unearned income exceeds $1,250. These thresholds also change annually, so check the current year's rules if you are a dependent.

When filing below the threshold still makes sense

Even if your income is below the filing threshold, you should consider filing if you had federal income tax withheld from your paychecks. Withholding is an advance payment of tax, and if you withheld more than you owe, you are owed a refund. The only way to recover that money is to file a return.

You should also file if you are owed a refundable tax credit, particularly the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit. These credits can result in a refund even if you owe no tax. The EITC is designed for low-income workers and can be worth thousands of dollars, but you have to file to claim it. Many people below the filing threshold miss out on refunds and credits straightforward because they do not file.

Filing is free through the IRS Free File program if your income is below a certain level, and many community organizations offer free tax preparation services. If you are unsure whether filing would benefit you, preparing a return to see what you are owed costs nothing.

What happens if you do not file when you should

If you are required to file and do not, the IRS can assess a failure-to-file penalty, which is usually 5 percent of the unpaid tax for each month the return is late, up to 25 percent. However, if you are owed a refund, there is no penalty — the IRS straightforward does not send you the money unless you file.

The statute of limitations for the IRS to assess tax is generally three years from the filing important date, but if you are owed a refund, you have three years to claim it by filing. After three years, the refund is forfeited. This is why filing even when you are below the threshold can be important — you do not want to leave money on the table.

If you have not filed for multiple years and you are below the filing threshold, you are not in when ready danger of an audit or penalty. However, if you had taxes withheld or are owed credits, filing back returns can recover that money. The IRS generally does not pursue non-filers who owe no tax, but it is always safer to file if you are unsure.

Frequently Asked Questions

Do I have to file if I earned $12,000 as a single person under 65?

No, not based on earned income alone. For 2023, the standard deduction for a single filer under 65 was $13,850, so $12,000 in wages does not trigger a filing requirement. However, if you had taxes withheld from your paychecks, you should file to recover the refund. Check the current year's standard deduction before deciding.

What if I earned $500 from a side gig and $1,000 in interest?

You likely have to file. Your earned income of $500 is below the standard deduction, but your unearned income of $1,000 exceeds the $1,250 threshold for unearned income alone. However, your total income of $1,500 is still below the standard deduction, so the rule depends on how the IRS treats the combination. Use the IRS Interactive Tax Assistant to confirm.

I am 67 and earned $15,000. Do I have to file?

No. For 2023, the standard deduction for a single filer 65 or older was $15,700, so $15,000 in earned income is below the threshold. The higher standard deduction for older filers means you can earn more before filing is required. Confirm the current year's amount, which increases annually.

If I am self-employed and earned $350 net, do I have to file?

No, because the self-employment threshold is $400. However, if you had any federal income tax withheld, or if you are owed the EITC or another refundable credit, filing would recover that money. Filing is free, so it may be worth doing even though you are not required to.

Can the IRS penalize me for not filing if I owe no tax?

No. The failure-to-file penalty applies only when you owe tax. If you are below the filing threshold and owe nothing, there is no penalty. However, if you are owed a refund and do not file within three years, you forfeit it, so filing is still worthwhile if you had withholding.
