Topic no. 553, Tax on a child's investment and other unearned income (Kiddie tax)

The following two situations may affect the tax and reporting of the unearned income of certain children.

  1. If your child's interest, dividends, and other unearned income total more than $2,500, it may be subject to a specific tax on the unearned income of certain children. See the Instructions for Form 8615, Tax for Certain Children Who Have Unearned Income for more information.
  2. If your child's only income is interest and dividend income (including capital gain distributions) and totals less than $12,500, you may be able to elect to include that income on your return rather than file a return for your child. See Form 8814, Parents' Election To Report Child's Interest and Dividends.

For either situation above to apply, your child must be required to file a return. For filing requirement information, refer to Do I need to file a tax return?

Tax for certain children who have unearned income

Use Form 8615PDF to figure the child's tax on unearned income over $2,500 if the child is under age 18, and in certain situations if the child is older (see below). Attach Form 8615 to the child’s tax return if all of the following conditions are met.

  1. The child's unearned income was more than $2,500.
  2. The child meets one of the following age requirements:
    • The child was under age 18 at the end of the tax year,
    • The child was age 18 at the end of the tax year and didn't have earned income that was more than half of the child's support, or
    • The child was a full-time student at least age 19 and under age 24 at the end of the tax year and the child didn't have earned income that was more than half of the child's support.
  3. At least one of the child's parents was alive at the end of the tax year.
  4. The child is required to file a tax return for the tax year.
  5. The child does not file a joint return for the tax year.

If your child is required to file Form 8615, the child may be subject to the net investment income tax (NIIT). NIIT is a 3.8% tax on the lesser of net investment income or the excess of modified adjusted gross income (MAGI) over a threshold amount. Use Form 8960, Net Investment Income Tax to figure this tax. For more information, see Topic no. 559 and Questions and answers on the net investment income tax.

Parents' election to report child's interest and dividends

You may be able to elect to report your child's interest, ordinary dividends, and capital gains distributions on your return. If you make this election, your child won't have to file a tax return.

  2. Your child's gross income was less than $12,500 for the tax year.
  3. Your child had income only from interest and dividends (including capital gain distributions and Alaska Permanent Fund dividends).
  4. No estimated tax payments were made for your child for the tax year, and no overpayment from the previous tax year (or from any amended return) was applied to the current tax year under your child's name and Social Security number.
  5. No federal income tax was withheld from your child's income under the backup withholding rules.
  6. Your child is required to file a return unless you make this election.
  7. Your child doesn't file a joint return for the tax year.
  8. You're the parent qualified to make the election or you file a joint return with your child's other parent.
