The first time a child’s brokerage account throws off dividends, many families get the same surprise: “Wait, kids can owe tax on this?” The kiddie tax threshold is the line the IRS uses to decide when a child’s unearned income may be taxed using the parent’s rate instead of the child’s rate. Once you know what counts, what doesn’t, and how to track it, the stress level drops fast.

The IRS explains the kiddie tax concept in Topic No. 553, including the key trigger: if a child’s interest, dividends, and other unearned income total more than $2,700 (tax year 2025), special rules may apply.
2025 Kiddie Tax Threshold in Plain English
The 2025 kiddie tax threshold is often misunderstood because families think “threshold” means “the amount a child can earn with no tax.” That isn’t quite it. This trigger is the point where the child’s unearned income can start being taxed at the parent’s marginal tax rate, depending on the child’s age and other conditions.
For many families, the key question is the unearned-income trigger the IRS highlights in Topic No. 553. Once the child’s unearned income crosses it, the return often needs more coordination and better documentation.
Kiddie Tax Threshold 2025: What Income Counts
When families ask about the 2025 threshold, they’re really asking what counts as unearned income. Unearned income is typically investment-type income, not pay for work.
Common items that usually count toward the unearned-income total:
- Taxable interest (bank interest and many savings products)
- Ordinary dividends and qualified dividends
- Capital gain distributions
- Net capital gains from selling investments
- Other investment-related unearned income
Common items that usually do not count toward the kiddie tax trigger because they are earned income:
- Wages from a job (W-2)
- Tips and other pay for work performed
- Self-employment income from actual work performed

Income Threshold for Kiddie Tax vs Filing Rules
A big source of confusion is mixing the income threshold for kiddie tax with filing requirements for dependents. They are related, but they are not the same.
Think of it like a two-gate system:
- Filing gate: does the child need to file a return at all based on their income and dependency rules?
- Kiddie tax gate: if the child files and has enough unearned income, do kiddie tax rules apply based on the child’s age and the unearned-income trigger?
Families often call that second gate the kiddie tax filing threshold because it’s the moment the return can shift from “simple” to “needs parent-rate math.”
Kiddie Tax Filing Threshold: The Common “Gotcha” Moments
Most families don’t run into kiddie tax rules because they’re doing anything exotic. They run into them because normal planning creates unearned income.
Common triggers that push families toward the filing threshold trigger:
- A custodial account or UTMA/UGMA account that grows and starts producing dividends
- A savings interest spike from a CD or high-yield savings product
- A sale of investments that creates capital gains
- Multiple accounts that look small individually but add up across the year
This is where tracking becomes the quiet hero. If you can see unearned income totals before December ends, you can plan instead of react. For families who want cleaner tracking across multiple accounts, outsourced bookkeeping services can help keep documents and totals organized year-round.
A 5-Step Year-End Routine to Prevent Kiddie Tax Surprises
If your goal is predictability, treat the unearned-income trigger like a dashboard light you check before year-end, not a surprise you discover in April.
- Total unearned income quarterly
Interest and dividends have a way of arriving in small pieces. Quarterly totals keep the picture honest. - Save every 1099 in one folder
One missing form can cause hours of rework. Keep it centralized. - Track sales inside the child’s account
Capital gains can be the difference between “fine” and “over the line.” - Keep parent and child documentation consistent
If numbers come from different sources, make sure the story matches across returns. - Ask early if you’re trending toward the 2025 trigger
A short review now can prevent a stressful filing later.
Families who want a structured, hands-off filing process often choose tax preparation outsourcing so paperwork doesn’t pile up into a springtime scramble.
Earned Income Isn’t the Trigger, But It Still Matters
The kiddie tax threshold focuses on unearned income, which is why a summer job usually doesn’t create the same calculation. Earned income can still affect filing requirements and the child’s overall taxable income picture.
If your child earns commissions, it helps to understand how those payments are taxed and reported. This guide on tax on commission payments explains what families should expect and what to keep for tax time.
Deductions and Kiddie Tax: What Helps and What Doesn’t
Families sometimes ask if deductions can reduce the kiddie tax threshold. The trigger itself is based on unearned income totals, but deductions can still influence the overall tax outcome and planning.
If you want a simpler mental model for deductions, these resources explain what changes and why:
The practical takeaway is that organized reporting and early totals usually matter more than last-minute tactics.
Kiddie Tax Income Threshold: When Getting Help Makes Sense
Most families can handle a small amount of unearned income. Where things get trickier is when there are multiple accounts, investment sales, or a parent return that already has complexity.
Here are good reasons to get help when the kiddie tax income threshold is in play:
- Your child received multiple 1099s (interest, dividends, capital gains)
- Investments were sold and cost basis details are unclear
- You’re coordinating multiple dependents and want consistency
- You want to reduce filing errors that lead to notices or amended returns
