The three filing tests the IRS uses for dependents
| Test | What it measures | Why it exists |
|---|---|---|
| Gross income test | Total income from all sources, earned and unearned combined | Covers dependents with a mix of income types that individually fall under either single-category threshold |
| Earned income test | Wages, tips, salaries, and self-employment income alone | Applies a higher threshold since this income reflects the dependent’s own labor |
| Unearned income test | Interest, dividends, capital gains, and similar investment income alone | Applies a much lower threshold, since this income often originates from a parent or custodial account |
Source: IRS Publication 501
The gap between earned and unearned thresholds is deliberate. A dependent with a summer job earning $15,000 in wages has no filing requirement from earned income alone, but a dependent with just $1,500 sitting in a custodial brokerage account earning dividends could trigger a filing requirement, because unearned income is far more likely to represent money that originated with a parent rather than the dependent’s own labor.
A dependent only needs to cross one of these tests to trigger a filing requirement.
Current-year income thresholds for single dependents
| Income type | Threshold |
|---|---|
| Earned income only (wages, tips, self-employment) | More than $16,100 for tax year 2026 ($15,750 for 2025) |
| Unearned income only (interest, dividends, capital gains) | More than $1,350 (for 2025 and 2026) |
| Combined earned and unearned income | The greater of $1,350, or the dependent’s earned income plus $450 — whichever is less, but never more than $16,100 (the regular 2026 standard deduction). |
Note: The thresholds are typically adjusted for inflation most years.
Special situations that trigger a filing requirement
The $400 self-employment threshold: Net self-employment earnings of $400 or more create a filing requirement on their own, separate from the earned-income threshold above, and can also trigger self-employment tax.
Withheld taxes: Even a dependent who falls under every threshold may want to file if federal tax was withheld from a paycheck. Filing is the only way to get it refunded.
The Kiddie Tax: Once a dependent’s unearned income exceeds a separate, lower threshold of $2,700, the overage can be taxed at the parent’s marginal rate rather than the dependent’s own rate.
Household employee wages: Income from working as a household employee, like babysitting or caregiving in someone’s home, has its own reporting nuances and can count toward a filing requirement even without a traditional W-2.
When a dependent should file even when not required to
If you’re below the threshold, you may consider filing if you had excess money withheld from your paycheck that would result in a refund. The other reason you might want to file a return even if you don’t have to is if you’re eligible for refundable tax credits. In both scenarios, this money is sitting with the IRS until you file a return.
Filing a dependent’s return, when it’s optional, doesn’t put the parent’s own dependent claim at risk—the two are separate questions. A dependent filing their own return to claim a refund has no bearing on whether a parent can still claim them, as long as the underlying dependency tests are otherwise met.
