It’s my annual Taxes from A to Z series! This time, it’s Tax Cuts and Jobs Act (TCJA) style. If you’re wondering whether you can claim home office expenses or whether to deduct a capital loss under the new law, you won’t want to miss a single letter.
K is for Kiddie Tax.
The so-called kiddie tax has been around since 1986. The kiddie tax was an effort to close a tax loophole for the wealthy; the idea was that taxing a child’s passive income at the same rate as that of their parents would mean there would be little to no reason to shift income. Since the creation of the tax, parents have scrambled to figure it out. The rules depend on many factors, including the age of the children, as well as the amount and source of the income.
The TCJA did not do away with the tax. The kiddie tax survived, but with some changes. Here’s what you need to know:
First, earned income, or income from wages, salary, tips or self-employment, is not subject to the kiddie tax. The TCJA did not change the way that earned income is taxed.
Second, the kiddie tax is largely figured the same as before: gross income less deductions. For 2018, the standard deduction amount for an individual who may be claimed as a dependent by another taxpayer cannot exceed the greater of $1,050 or the sum of $350 and the individual’s earned income (not to exceed the regular standard deduction amount).
Third, the kiddie tax still applies to unearned income. Unearned income typically means investment income like dividends, capital gains and interest; those amounts are subject to the kiddie tax.
The general rule is this: If your child is under the age of 19 (or under the age of 24 and a full-time student), the kiddie tax applies once unearned income hits $2,100 ($2,200 in 2019). If that’s the case, your child has unearned income subject to the kiddie tax and must file a federal form 8615, Tax for Certain Children Who Have Unearned Income (downloads as a PDF).
That doesn’t necessarily mean that your child necessarily has to file a separate tax return. Under the TCJA, your child must pay taxes on their unearned income but if that amount is more than $1,050 ($1,100 in 2019), but less than $10,500 ($11,000 in 2019), you may be able to elect to include that income on your return rather than file a separate return for your child.
Finally, the rate of the kiddie tax may be higher for some families under the TCJA. Unearned income is now taxed at the rates paid by trusts and estates. Those rates can be as high as 37%. And while that sounds the same as for individuals, it’s not. Tax rates for trusts and estates “climb the brackets” faster than individuals which means that since the rates are compressed, you hit the top rate much sooner. For example, a married couple didn’t hit the top tax bracket of 37% until income is $600,001 in 2018, but taxable income hit the top rate of 37% for trusts and estates at just $12,501 in 2018.
Got it? So, with those explanations and caveats, here’s a quick and dirty formula for most taxpayers:
Child’s net earned income + child’s net unearned income – child’s standard deduction = child’s taxable income
- A child’s net earned income is taxed as normal.
- A child’s net unearned income that exceeds the unearned income threshold ($2,100 for 2018 or $2,200 for 2019) is subject to the kiddie tax and is taxed at the rates that apply to trusts and estates.
Keep in mind that these rules apply to children who are dependents. Those who are not dependents because of their age or filing status (such as children who are married), level of support or those who are emancipated have a different set of rules. Other exceptions may apply: for example, children with earned income totaling more than half the cost of their support are not subject to the kiddie tax rules.
Again, the rules can be complicated depending on your specific facts and circumstances. If you’re still scratching your head, be sure to consult with your tax professional.
