Introduction
Every year, millions of Americans wonder if they’re required to file a federal income tax return. For 2025 (covering income earned in 2024), the IRS sets income thresholds based on your filing status, age, and income type. Knowing these rules is important to avoid penalties — and to ensure you don’t miss out on valuable refunds or tax credits.
Standard Filing Thresholds
For most taxpayers, filing is required once your gross income reaches the standard deduction for your filing status. Below are the 2024 tax year thresholds (for returns filed in 2025):

Special Situations
Some people must file even if their income is below these thresholds:
- Self-Employed Individuals: If your net earnings are $400 or more, you must file and pay self-employment tax.
- Dependents: Students and children claimed as dependents must file if:
- Earned income is over $14,600
- Unearned income (interest, dividends) is over $1,300
- Or their combined income passes IRS limits.
- Other Taxable Events: Filing is also required if you had early withdrawals from retirement accounts, owe alternative minimum tax, or received advance health insurance premium credits.
Filing Even When Not Required
Even if you earn less than the filing threshold, submitting a return can benefit you:
- Refundable Tax Credits: Such as the Earned Income Tax Credit (EITC) or Child Tax Credit.
- Refund on Withholding: If taxes were withheld from your paycheck, you must file to claim a refund.
Common Misunderstandings
- I didn’t make much money, so I don’t need to file: That’s only true if you’re under the threshold and no special rules apply.
- Seniors don’t have to file: Seniors must still file if their income exceeds the threshold. Retirement withdrawals and pensions may make filing necessary.
- Students don’t earn enough to file: Students with part-time jobs, scholarships, or investments may have to file — even if parents claim them as dependents.
Conclusion
The IRS filing requirements for 2025 depend on income, age, and filing status, with special rules for self-employed individuals, dependents, and retirees. Even if you’re not required to file, doing so may help you claim refunds or credits.
