Generally no, unless you had self-employment income ($400+), owe special taxes, or qualify for refundable credits.

Possibly. If your combined income (SS + other income) exceeds $25,000 (single) or $32,000 (married filing jointly), up to 85% may be taxable.
3. What if I’m claimed as a dependent?
Different rules apply. For 2024, single dependents must file if they have:
