The minimum amount or threshold of income requiring a dependent to file a federal tax return.
2021 filing requirements for dependents under 65
• Earned income of more than $12,550.
• Unearned income of more than $1,100 (like from investments or trusts).
Different thresholds apply for dependents who are 65 or older or blind, or who have both earned income (like wages, salaries, and tips) and unearned income.
♦ You must include on your Marketplace application income for any dependent required to file a tax return.
Taxpayers who are not dependents have other filing thresholds.
