When Must a Dependent File Their Own Tax Return
Question askedWhen does a dependent's income require them to file their own return?
Quick answer: For 2025, a dependent generally must file their own return if their earned income, unearned income, or total gross income exceeds certain thresholds that depend on their age and blindness status — for a single dependent who is not 65 or older or blind, the key numbers are unearned income over $1,350, earned income over $15,750, or gross income over the larger of $1,350 or earned income (up to $15,300) plus $450.
How it works
IRS Publication 501 confirms 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 laid out in Publication 17's filing-requirements table for dependents.
For definitions: unearned income includes taxable interest, ordinary dividends, and capital gain distributions, as well as unemployment compensation, taxable social security benefits, pensions, annuities, and distributions of unearned income from a trust, while earned income includes salaries, wages, tips, professional fees, and taxable scholarship and fellowship grants. Gross income is the total of your earned and unearned income.
For a single dependent who is not 65 or older and not blind, Publication 17 states the dependent must file a return if any of the following apply: their unearned income was more than $1,350; their earned income was more than $15,750; or their gross income was more than the larger of $1,350, or their earned income (up to $15,300) plus $450.
These figures are adjusted annually for inflation, so they will differ in other years — confirm the year-specific numbers before relying on them.
Special situations that matter
- Child's own earnings: Amounts a child earns by performing services are included in the child's gross income and not the gross income of the parent, even if under local law the child's parent has the right to the earnings — but if the child doesn't pay the tax due, the parent is liable for the tax.
- Parent filing for a child: If a dependent child must file an income tax return but can't file due to age or any other reason, a parent, guardian, or other legally responsible person must file it for the child.
- Election to report a child's unearned income on the parent's return: Instead of the child filing, a parent may elect to include the child's interest and dividend income on the parent's own return under certain conditions, including that your child was under age 19 (or under age 24 if a student) at the end of 2025, that your child had gross income only from interest and dividends (including capital gain distributions and Alaska Permanent Fund dividends), and that income was less than $13,500, and several other conditions listed in Publication 501 (e.g., the child doesn't file a joint return, and no estimated payments or withholding occurred under the child's SSN). If the election is made, you may be able to include your child's interest and dividend income on your tax return, and if you do this, your child won't have to file a return.
In practice
The filing-requirement thresholds are separate from — and generally lower than — the thresholds that apply to someone who isn't a dependent, because a dependent's standard deduction is limited. Whether a specific dependent must file turns on: their age (under vs. 65+) and blindness status, whether their income is earned, unearned, or both, and whether a parent instead elects to report the child's investment income directly.
Because these thresholds change every year and small factual differences (age cutoffs, type of income, marital status) change the outcome, it's worth having a CPA confirm the correct year's figures and whether the parental election makes sense for your family.
