The kiddie tax and household employees

Two family tax rules that surprise people. One is about money in your child’s name; the other is about the person you pay to help at home.

They have nothing to do with each other except that both live inside ordinary family life and both arrive uninvited. A grandparent’s gift of stock turns into a child’s tax return at the parents’ rate. The aide who comes three days a week to help with Dad turns the family into an employer with payroll forms to file. Neither is hard once you know the rule.

Part one: the kiddie tax

Parents used to park investments in their children’s names to use the children’s low rates. This is the rule that stopped it.

The kiddie tax applies to a child’s unearned income: interest, dividends, capital gains, taxable scholarship money, and distributions from an inherited IRA. Wages are not touched. The unearned income is stacked in three tiers.

Kiddie tax tiers, 2026
Child’s unearned incomeAmountTaxed at
First tier$0–$1,350Not taxed
Second tier$1,350–$2,700The child’s own rate
Above the lineOver $2,700The parents’ marginal rate, computed on Form 8615

The parents’ rate includes the capital gains rates if the child’s income is gains or qualified dividends. The child’s return is always finished after the parents’.

Which children

Every child under 18 at year end. A child who is 18, or a full-time student from 19 through 23, is also covered unless their own earned income paid more than half their support. A 22-year-old in college on the parents’ dime is in.

Whose rate, and who files

The parent the child lives with, or the higher-income parent if they file separately. A dependent child with unearned income over $1,350 generally must file a return (y the year’s filing line). When a child must file.

Custodial accounts, gifted stock, and the parents’ election

Where the kiddie tax actually bites, and the one shortcut the IRS offers.

A custodial account (UTMA or UGMA) is the usual home for money given to a child. The money is legally the child’s; a parent or grandparent manages it until the child reaches the age set by state law. Every dollar of interest, dividends and gains it produces is the child’s income, and past $2,700 the parents’ rate applies. A growth fund held for years can throw off a large gain the year the custodian rebalances, taxed as if the parents had sold it.

The same logic defeats a popular idea: giving appreciated stock to a child so the child sells it at a low rate. The gift carries the parents’ cost basis, so the whole gain is still there when the child sells, and everything above $2,700 is taxed at the parents’ capital gains rate, exactly where it would have been taxed anyway. It works only for small gains, or for a child outside the rule. How capital gains are taxed.

A worked example

Emma is 12. Her UTMA account earned $5,000 of interest in 2026, and her parents file jointly in the 24% bracket. The first $1,350 is untaxed. The next $1,350 is taxed at Emma’s own rate, which is small. The remaining $2,300 is taxed at her parents’ 24%, or $552, on Form 8615. Had it been $5,000 of qualified dividends, the top tier would use her parents’ 15% capital gains rate, about $345.

Form 8615 or Form 8814? Form 8615 goes on the child’s own return and handles any unearned income. Form 8814 is the parents’ election: if the child’s income is only interest and dividends and totals less than $13,500, the parents may report it on their own return and skip the child’s. It saves a filing, but it raises the parents’ AGI, which can trim other credits, and it usually costs a little more. We run it both ways.

What avoids the tax: 529 plans, a Roth IRA funded from the child’s own wages, and growth investments held until the kiddie tax years are over. A child who inherits an IRA should spread the withdrawals.

Behind the scenes

The Form 1099 for a custodial account comes in the child’s name and is mailed to whoever opened the account, often a grandparent; parents routinely don’t know it exists. We ask whether anyone has ever opened an account for the child, and we pull the IRS wage-and-income transcript for the child’s number before the return is final. That is how we find the dividends nobody mentioned.

Part two: who is a household employee

If you pay someone to work in or around your home and you control how and when the work is done, that person is your employee. The IRS calls it the “nanny tax”; nannies are a minority of the cases we see.

Usually an employee

A nanny on a schedule. A caregiver you hired directly for an aging parent. A housekeeper on set days. A yard worker you pay by the hour and direct yourself.

Usually not

Agency staff; the agency is the employer. A cleaning company or lawn service with its own business and other customers. A contractor hired for a job. You owe nothing but the invoice.

The test

Control. If you decide the hours and the tasks, it is employment, whatever you both call it and whether the worker is part-time, paid in cash, or a friend of the family. The case that surprises people most is the aide paid from Mom’s checking account for three years: Mom is the employer, and the child with power of attorney has to make the filings happen. It often surfaces at the final return, which is too late.

What a household employer owes and files

It all rides along with your own Form 1040. No separate business return.

Household employer thresholds and taxes, 2026
TaxApplies once you payWhat it is
Social Security and Medicare (FICA)$3,000 in the year, to one worker15.3% of cash wages: 7.65% withheld from the worker and 7.65% from you; you may pay both halves
Federal unemployment (FUTA)$1,000 in any calendar quarter, all workers combinedA small percentage of the first $7,000 of each worker’s wages
Federal income tax withholdingOnly if the worker asks and you agreeOptional

The FICA line is indexed each year, so confirm the current amount. Once you cross it, the tax applies to all the year’s wages, not just the excess.

1

Get an employer ID number and register in Colorado

A free EIN from the IRS, then registration with the Colorado Department of Labor and Employment for state unemployment insurance.

2

Pay, and keep a simple record

Hours, gross pay, dates. Withhold the worker’s 7.65% or pay it for them; many families do.

3

W-2 by January 31

The worker gets a Form W-2 by January 31, with a copy to Social Security. This is what gives the worker Social Security credit for the year.

4

Schedule H with your 1040

The year’s FICA and FUTA are totaled on Schedule H and added to your own tax. Raise your withholding or make an estimated payment so the bill doesn’t land all at once.

Paying family: wages to your spouse, your child under 21, and in most cases your parent are exempt from FICA and FUTA; the parent exemption has exceptions when the parent is caring for your young or disabled child under certain conditions. Students under 18 are also exempt. An adult child over 21 you pay to care for you is a regular household employee.

Behind the scenes

The child and dependent care credit requires the provider’s name, address and taxpayer identification number. When the provider is an individual rather than a daycare center, we ask who controls the work, because the credit and Schedule H are two halves of the same fact. Nanny expenses with no Schedule H attached are one of the easiest mismatches for the IRS to spot.

The risk of ignoring it is not usually an audit. It is the day the relationship ends. The caregiver files for unemployment and the state finds no employer account; the nanny applies for Social Security and has no earnings record. Each leads back to you, with back taxes, penalties and interest for every year.

The Colorado side

Short, because Colorado mostly follows along.

Kiddie tax

Colorado starts from federal taxable income and taxes it at a flat 4.40%, with no separate kiddie tax computation. If the parents elect Form 8814, the income lands on their Colorado return instead. Colorado income tax basics.

Household employers

Colorado requires household employers to register for state unemployment insurance and pay premiums on wages; the thresholds and rates are set by the Department of Labor and Employment, not the DOR. FAMLI premiums may apply too.

Common questions

My 16-year-old earned $6,000 at a summer job. Kiddie tax?

No. Wages are earned income, taxed at the child’s own rate, and $6,000 is under the standard deduction, so there is no federal tax. A good year to open a Roth.

Grandma put $19,000 of stock in a UTMA for my daughter. Is that taxable?

The gift itself is not income and is within the annual gift exclusion. The dividends, and the gain when the stock is sold, are your daughter’s income, and above $2,700 a year they are taxed at your rate. Gift tax basics.

Can I just give the nanny a 1099 instead?

No. A 1099 is for independent businesses, and a nanny working your hours in your home is not one. The IRS and the state reclassify these, and the back taxes fall on you.

A child with an account, or a caregiver on the payroll?

Bring the account statements, or the hours and pay for the person helping at home, and we’ll file the forms with your return. In person in Lone Tree or remotely, year round.
