Taxes for Kids Under 18: A Parent's Guide

Short answer

Kids under 18 may need to pay taxes if they earn income, such as from a job or investments. Parents should understand how their child's income is taxed, when the child must file a tax return, and how to handle withholding or estimated payments. This helps teach financial responsibility and ensures compliance with IRS rules.

What Are Taxes for Kids Under 18?

Taxes for kids under 18 work largely like taxes for adults: if a child earns income, they may owe taxes on that money. Income can come from a part-time job, freelancing, or investment earnings like interest or dividends. However, the tax rules have some special considerations for minors, including different thresholds for when they must file a return or pay taxes. Parents should know these basics to support their child in managing money and meeting tax responsibilities.

Kids typically use a Social Security Number (SSN) for tax reporting. If a child earns income, that income must be reported to the IRS, and taxes may be due depending on the amount and type of income. Even children with small earnings might need to file a tax return to claim refunds or comply with tax laws.

Frequently asked questions

When does a child under 18 have to file a tax return?

A child must file if their earned or unearned income exceeds IRS thresholds, which vary yearly. Even if no tax is owed, filing may be needed to claim a refund, especially if taxes were withheld. Check current IRS rules or use tax software to determine filing requirements.

Can parents claim their child’s income on their own tax return?

No, a child’s income is reported on their own tax return. Parents claim the child as a dependent but cannot combine the child’s income with theirs. Exceptions like the Kiddie Tax affect how unearned income is taxed but not income reporting.

How does a child get a Social Security Number for taxes?

Parents apply for an SSN for their child through the Social Security Administration, often when the child is born. The SSN is necessary for tax reporting, opening bank accounts, and claiming dependents on tax returns.

What is the difference between earned and unearned income for kids?

Earned income comes from work, like wages or salaries. Unearned income comes from investments, gifts, or interest. Earned income is taxed differently and usually has a higher filing threshold for kids than unearned income.

How can parents help kids avoid paying too much tax?

Parents can assist by ensuring proper withholding through W-4 forms, teaching kids about deductions and credits, managing investment income to minimize Kiddie Tax impact, and encouraging savings in tax-advantaged accounts.

Are there special tax credits or deductions for kids under 18?

Kids who work and file returns can claim the standard deduction for dependents, which reduces taxable income. Some tax credits may apply depending on income, but many credits are claimed by parents on their own returns for dependents.
