Tax on Income of Minor Children

Prior to 1986, parents found it beneficial to give income-earning assets to their minor children since the children were generally in a lower income tax bracket. The Tax Reform Act of 1986 contained provisions that limit the benefit of shifting income to certain minor children. The net unearned incomeunearned incomeIncome derived from sources other than wages, salary, self-employment, partnership; e.g., interest and dividends. of minor children may now be taxed at their parents’ rates. This parental tax rate now applies to children who are younger than 18 years old at the end of the year, have at least one living parent, and have “net unearned income” for the year. Although there is no statutory definition for a parent, the term is generally considered to mean a parent or step-parent of the child.

For purposes of determining the child’s income subject to the parental tax rate, net unearned income of a minor child is computed as follows:

Unearned Income$xxxx
Less the greater of:
  1. $900 (the child’s standard deduction), or

  2. The allowable itemized deductions directly connected with the production of the unearned income

(xxx)
Subtotal$xxxx
Less statutory deduction(900)
Net unearned income$xxxx

If the net unearned income is zero or less, the child’s tax is calculated using the child’s tax rate. However, if the amount is positive, the child’s tax is calculated by applying the parent’s tax rate, if higher, to that amount.

Example

Carrie and Carl have two children, Brie (age 6) and Brienna (age 9). Brie received $3,000 in interest income and Brienna received $1,900 in interest income during 2008. Brie and Brienna did not pay any investment expenses for the year. Carrie and Carl have taxable income for the year of $45,050. Brie and Brienna’s 2008 income tax is calculated as follows:

Step 1: Calculate Net Unearned IncomeBrieBrienna
Unearned income$3,000$1,900
Less the greater of:
$900 (standard deduction), or  
investment expenses(900)(900)
 $2,100$1,000
Less statutory deduction(900)(900)
Net unearned income$1,200$100
Step 2: Calculate the Total Parental Tax
Parents’ taxable income$45,050
Plus: the children’s net unearned income ($1,200 + $100)1,300
Revised taxable income$46,350
Tax on revised income (from tax rate schedule)$6,154
Tax on parent’s regular income ($45,050)(5,959)
Total parental tax$199
Step 3: Allocate Total Tax
Brienna’s parental tax = [$100/($1,200 + $100)] × $195 = $15
Brie’s parental tax = [$1,200/($1,200 + $100)] × $195 =$180 
Step 4: Calculate Total TaxBrieBrienna
Adjusted gross income$3,000$1,900
Less: personal exemption00
Less: standard deduction(900)(900)
Taxable income$2,100$1,000
Less: net unearned income(1,200)(100)
Regular taxable income$900$900
Regular tax on $900$91$91
Plus allocable parental tax$180$15
Total tax$271$106

Both Brie and Brienna must include a Form 8615, Tax for Certain Children Who Have Investment Income of More Than $1,800, with their individual income tax returns.

If a child’s parents are divorced, the taxable income of the parent with custody is used to calculate the parental tax. Also, if married parents file separate returns, the parent’s return with the larger amount of taxable income is used in the calculation.

If certain conditions are met, parents may elect to include a child’s (under 18) gross income on the parents’ tax return. The election eliminates the child’s return filing requirements and saves the parents the trouble of filing the special calculation Form 8615 for the “Kiddie tax.” To qualify for this election the following conditions must be met:

  1. The child’s gross income is from interest and dividends only.

  2. The gross income is more than $900 and less than $9,000.

  3. No estimated tax has been paid for the child and the child is not subject to backup withholding.
