The requirement to file a federal tax return depends on several factors including filing status, age, and gross income. Here are the key thresholds and situations:
Income Thresholds for Most Taxpayers:
For 2025, a return must be filed if gross income meets or exceeds these amounts [1]:
Single: $15,000 (under 65) or $17,000 (65 or older)
Married Filing Jointly: $31,500 (both under 65), $33,100 (one spouse 65+), or $34,700 (both 65+)
Married Filing Separately: $5 (any age)
Head of Household: $23,625 (under 65) or $25,625 (65 or older)
Qualifying Surviving Spouse: $31,500 (under 65) or $33,100 (65 or older)
Special Filing Requirements:
A return must be filed regardless of income if any of these conditions apply [1]:
Owing special taxes (alternative minimum tax, additional tax on qualified plans, household employment taxes, or Social Security/Medicare tax on unreported tips)
Receiving HSA, Archer MSA, or Medicare Advantage MSA distributions
Having net self-employment earnings of at least $400
Receiving more from a church or qualified church-controlled organization exempt from employer Social Security and Medicare taxes
Having advance Premium Tax Credit payments made for coverage through the Marketplace
Dependents:
Different rules apply for individuals who can be claimed as dependents, with lower income thresholds based on earned versus unearned income [2].
Even when not required, filing may be beneficial to claim refunds of withheld taxes or refundable credits like the Earned Income Credit or Additional Child Tax Credit [1].
