When must a dependent file their own tax return

TY 2025 Individual Income Tax 1 source 2026-07-16

Question: When does a dependent's income require them to file their own return?

Quick answer: For 2025, whether a dependent must file their own return depends on the type of income (earned vs. unearned), the total amount, and whether they're single or married, and 65-or-older/blind. IRS Publication 501's Table 2 lays out specific dollar thresholds for each situation.

How it works

A "dependent" here means someone who can be claimed as a dependent on another person's return (usually a parent). 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.

Two income categories matter:

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.
Earned income — includes salaries, wages, tips, professional fees, and taxable scholarship and fellowship grants.

Gross income is simply the total of both.

Single dependents (not 65+/not blind)

A single dependent must file if any of the following apply:

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

Higher thresholds apply — 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), or 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 (not 65+/not blind)

In addition to the income thresholds (similar to single dependents), there's an extra trigger: Your gross income was at least $5 and your spouse files a separate return and itemizes deductions. Otherwise the thresholds mirror the single-dependent amounts (unearned income more than $1,350; earned income more than $15,750; or gross income more than the larger of $1,350, or earned income up to $15,300 plus $450).

Married dependents who are 65+ or blind

The thresholds rise: unearned income more than $2,950 ($4,550 if 65 or older and blind); earned income more than $17,350 ($18,950 if 65 or older and blind), plus the same spouse-itemizing trigger and a gross income test.

What it depends on

Single vs. married dependent
Age 65+ and/or blind status
Whether the income is earned or unearned
Whether a married dependent's spouse itemizes deductions on a separate return

Note: these are 2025 figures; amounts adjust annually for inflation, and the tables above come from Publication 501.

Because dependent filing rules involve several thresholds that interact (and can shift with law changes like the 2025 Act), it's worth confirming your exact numbers with a CPA before deciding whether to file.
