A: It depends on how much income you have—and, more importantly, the type of income you received! Dependents have different filing rules from other taxpayers.

• Even a relatively small amount of investment income can trigger a filing requirement.
For 2026, a typical single dependent under age 65 generally needs to file if they have more than $1,350 of unearned income, such as taxable interest, dividends, or investment gains. By comparison, if the dependent has only earned income, such as wages, the threshold is generally $16,100.• That can lead to a surprising result.
For example, a dependent with $2,000 of taxable investment income generally would need to file a tax return, while a dependent with only $10,000 of earned income, such as wages, generally would not.If a dependent has both earned and unearned income, an additional combined-income rule can also apply.• Being claimed as a dependent doesn’t prevent you from filing your own return.
A parent or someone else may still be able to claim you as a dependent even when you are required to file your own tax return. These are separate questions.

Bottom Line:  If you’re a dependent, don’t simply compare your income with the regular $16,100 standard deduction for a single taxpayer in 2026 and assume you don’t need to file. A relatively small amount of investment income can trigger a filing requirement. For dependents, whether income is earned or unearned can make a big difference.
