Tax season can feel overwhelming—especially when you’re not even sure if you need to file. The good news? The IRS has clear guidelines to help you decide. And sometimes, filing a return is smart even when it’s not required. Let’s break it down.

Who Generally Must File?

You’ll likely need to file a federal tax return for 2025 if any of these apply:

• Your income exceeds the filing threshold for your age and filing status (see tables below)
• You earned $400 or more in net self-employment income (freelance work, gig jobs, side hustles)
• You had other special tax situations (like owing certain taxes or receiving advance premium tax credits)

Income Thresholds: Are You Required to File?

These amounts apply to your gross income (before deductions) for tax year 2025:

If You Were Under 65 at the End of 2025:

Filing Status	Minimum Gross Income to File
Single	$15,750+
Head of Household	$23,625+
Married Filing Jointly (both under 65)	$31,500+
Married Filing Jointly (one spouse 65+)	$33,100+
Married Filing Separately	$5+
Qualifying Surviving Spouse	$31,500+

If You Were 65 or Older at the End of 2025:

Higher thresholds apply for seniors:

• Single: $17,550+
• Head of Household: $25,625+
• Married Filing Jointly (one spouse 65+): $33,100+
• Married Filing Jointly (both 65+): $34,700+
• Qualifying Surviving Spouse: $33,100+

💡 Note: “Married filing separately” has a $5 threshold if your spouse itemizes deductions—essentially meaning you must file in that situation.

Special Rules for Dependents

If someone else (like a parent) can claim you as a dependent, different—and lower—thresholds apply. You must file if:

• Your unearned income (interest, dividends, capital gains) exceeds $1,350 (under 65) or $3,350 (65+)
• Your earned income (wages, tips) exceeds $15,750 (under 65) or $17,750 (65+)
• Your gross income exceeds the larger of $1,350 or your earned income (up to $15,300) plus $450

Blind dependents receive even higher thresholds—adding roughly $2,000 to unearned income limits.

Why File Even When You Don’t Have To?

You might not be required to file—but you could be leaving money on the table. Consider filing anyway if:

✅ Your employer withheld federal income tax from your paycheck (you could get a refund)
✅ You qualify for refundable credits like the Earned Income Tax Credit (EITC) or Child Tax Credit
✅ You made estimated tax payments during the year
✅ You want to claim education credits or other valuable deductions

Real example: A college student earned $12,000 in 2025—below the filing threshold. But their employer withheld $800 in federal taxes. By filing, they’d get that $800 back as a refund.

Still Unsure?

The IRS offers an interactive tool—”Do I Need to File a Tax Return?”—that walks you through your specific situation with simple questions. It’s the most reliable way to confirm your filing requirement.

Bottom line: Don’t assume you’re off the hook just because your income was low. Filing a simple return could put cash back in your pocket—and it’s often faster and easier than you think with free filing options available for most taxpayers.
