The term "kiddie tax" was introduced by the Tax Reform Act of 1986. The IRS introduced this rule to keep parents from shifting their investment income to their children and have this income taxed at their child's lower tax rate. The law requires a child's unearned income (generally dividends, interest, and capital gains) above a certain amount ($2,000 in 2013) to be taxed at their parent's tax rate. Here is what you need to know.

  1. Maximize your low tax investment options. Look to generate gains on your child's investment accounts to maximize the use of your child's kiddie tax threshold each year. You could consider selling stocks to capture your child's investment gains and then buy the stock back later to establish a higher cost basis.
  2. Be careful where you report a child's unearned income. Don't automatically add your child's unearned income to your tax return. It might inadvertently raise your taxes in surprising ways by exposing more income to the Alternative Minimum Tax or reducing your tax benefits in other programs like the American Opportunity Credit.
  3. Leverage gifts. If your children are not maximizing their tax-free investment income each year consider gifting funds to allow for unearned income up to the kiddie tax thresholds. Just be careful, as these assets can have an impact on a child's financial aid when approaching college age years.

Properly managed, the "kiddie tax" rules can be used to your advantage. But if not properly managed, this part of the tax code can create an unwelcome surprise at tax time.
