Question askedWhen does a dependent need to file their own tax return?

Quick answer: For 2025, a dependent must file their own return if their earned income, unearned income, or gross income exceeds certain thresholds that depend on whether they're single or married and whether they're 65+ or blind — or if certain other special situations apply.

What it depends on

IRS Publication 501 explains that a person who is a dependent may still have to file a return, depending on the person's earned income, unearned income, and gross income. The specific dollar thresholds for 2025 are:

Single dependents under 65 and not blind — you must file if:

  • Your unearned income was more than $1,350.
  • Your earned income was more than $15,750.
  • Your gross income was more than the larger of $1,350, or your earned income (up to $15,300) plus $450.

Single dependents who are 65+ or blind — you must file if:

  • Your unearned income was more than $3,350 ($5,350 if 65 or older and blind).
  • Your earned income was more than $17,750 ($19,750 if 65 or older and blind).
  • Your gross income was more than the larger of $3,350 ($5,350 if 65 or older and blind), or your earned income (up to $15,300) plus $2,450 ($4,450 if 65 or older and blind).

Married dependents under 65 and not blind — you must file if:

  • Your gross income was at least $5 and your spouse files a separate return and itemizes deductions.
  • Your unearned income was more than $1,350.
  • Your earned income was more than $15,750.
  • Your gross income was more than the larger of $1,350, or your earned income (up to $15,300) plus $450.

Married dependents who are 65+ or blind — you must file if:

  • Your gross income was at least $5 and your spouse files a separate return and itemizes deductions.
  • Your unearned income was more than $2,950 ($4,550 if 65 or older and blind).
  • Your earned income was more than $17,350 ($18,950 if 65 or older and blind).
  • Your gross income was more than the larger of $2,950 ($4,550 if 65 or older and blind), or your earned income (up to $15,300) plus $2,050 ($3,650 if 65 or older and blind).

Definitions that matter:

  • Unearned income includes taxable interest, ordinary dividends, and capital gain distributions, and also includes unemployment compensation, taxable social security benefits, pensions, annuities, and distributions of unearned income from a trust.
  • Earned income includes salaries, wages, tips, professional fees, and taxable scholarship and fellowship grants. Gross income is the total of your unearned and earned income.

Other situations that trigger filing: Publication 501 also notes a dependent must also file if one of the situations described in Table 3 applies (that table isn't in the documents provided, but it typically covers things like owing special taxes, e.g., self-employment tax).

Parental responsibility: If the child can't file for themselves, a parent, guardian, or other legally responsible person must file it for the child. Also worth knowing: you may be able to include your child's interest and dividend income on your own tax return instead, in which case your child won't have to file a return — this election has its own eligibility conditions (e.g., an age limit).

Bottom line: Even below these thresholds, a dependent may want to file voluntarily to get a refund of withheld taxes. Because the numbers change every year and interact with age/blindness and filing status, it's worth double-checking with a CPA before assuming no return is needed.
