You generally need to file a federal tax return in 2025 if your gross income in 2024 meets or exceeds certain thresholds based on your filing status and age. Here are the key income thresholds for filing:

• Single filers:
  • Under age 65: $14,600 or more
  • Age 65 or older: $16,550 or more
• Married filing jointly:
  • Both spouses under 65: $29,200 or more
  • One spouse 65 or older: $30,750 or more
  • Both spouses 65 or older: $32,300 or more
• Head of household:
  • Under age 65: $21,900 or more
  • Age 65 or older: $23,850 or more
• Married filing separately:
  • $5 or more, regardless of age
• Qualifying surviving spouse:
  • Under age 65: $29,200 or more
  • Age 65 or older: $30,750 or more
• Self-employed individuals:
  • Must file if net earnings are $400 or more, regardless of age or filing status

If your income is below these thresholds, you may not be required to file, but you might still want to file to claim a refund of withheld taxes or refundable credits. These thresholds reflect gross income, which includes all income you receive in the form of money, goods, property, and services that are not exempt from tax
