Quick Answer

Yes, the kiddie tax threshold increased to $2,800 for 2026 (up from $2,650 in 2025), and the tax calculation method was simplified. Children's unearned income over $2,800 is now taxed at the child's marginal rate based on their total income, not the parent's rate.

What changed with the kiddie tax for 2026?


The kiddie tax rules were significantly simplified for 2026. The most important changes:


1. Higher threshold: Unearned income threshold increased to $2,800 (from $2,650)

2. New tax calculation: Children's excess unearned income is taxed at the child's own marginal rate, not the parent's rate

3. Simplified filing: No more complex parent rate calculations or elections


According to IRS Publication 929, these changes affect children under 18 (or under 24 if full-time students) with unearned income exceeding $2,800.


How the new kiddie tax works in 2026


Step 1: Determine if kiddie tax applies

  • Child must be under 18 (or under 24 if full-time student with earned income ≤ half of support)
  • Unearned income must exceed $2,800
  • At least one parent must be alive

  • Step 2: Calculate the tax

  • First $1,400 of unearned income: Tax-free
  • Next $1,400 of unearned income: Taxed at child's rate (typically 10%)
  • Remaining unearned income: Taxed at child's marginal rate based on total income

  • Example: 16-year-old with investment income


    Sarah (age 16) has:

  • $500 earned income (part-time job)
  • $8,000 unearned income (dividends and capital gains)
  • Total income: $8,500

  • Under old rules (2025 and earlier):

  • Excess unearned income ($8,000 - $2,650 = $5,350) taxed at parent's marginal rate
  • If parents in 24% bracket: $5,350 × 24% = $1,284 kiddie tax

  • Under new 2026 rules:

  • First $1,400 unearned income: $0 tax
  • Next $1,400 unearned income: $1,400 × 10% = $140
  • Remaining $5,200: Taxed at Sarah's rate based on $8,500 total income
  • Sarah's marginal rate on $8,500 income: 10% (well below 12% threshold)
  • Remaining tax: $5,200 × 10% = $520
  • Total kiddie tax: $140 + $520 = $660

  • Tax savings: $1,284 - $660 = $624 less tax



    Who benefits most from the changes


    Families that benefit:

  • High-income parents (previously pushed kiddie tax to 32-37% rates)
  • Children with moderate unearned income ($3,000-$15,000 range)
  • Families using UTMA/UGMA accounts for college savings

  • Minimal impact:

  • Children with very low unearned income (under $2,800)
  • Families where parents are already in low tax brackets
  • Children with enormous unearned income (may hit higher brackets anyway)

  • Tax planning opportunities


    New strategies for 2026:

  • Shifting more income to children may now make sense
  • UTMA/UGMA accounts became more attractive
  • Family partnerships or S-corps with children as owners need reconsideration
  • Timing of capital gains in children's accounts can be optimized

  • What you should do


    1. Review existing UTMA/UGMA accounts — the tax burden may have decreased significantly

    2. Consider shifting more investment income to children if parents are in high brackets

    3. Re-examine family business ownership structures where children own interests

    4. Use our refund estimator to calculate potential savings from the rule changes

    5. File Form 8615 (Kiddie Tax) if your child's unearned income exceeds $2,800


    Key takeaway: The 2026 kiddie tax changes eliminate the harsh parent-rate taxation, potentially saving families hundreds or thousands of dollars annually when children have significant unearned income over $2,800.

    Key Takeaway: The kiddie tax was simplified for 2026, with children's unearned income over $2,800 now taxed at the child's own rate instead of the parent's higher rate, creating significant savings for many families.

    High-income parents who previously faced steep kiddie tax rates and can now benefit from income shifting strategies

    How high earners benefit from kiddie tax changes


    If you're in the 32% or 37% tax bracket, the kiddie tax changes create massive planning opportunities. Previously, your children's unearned income over $2,650 was taxed at your marginal rate, creating a punitive tax on family wealth transfers.


    Example: High-earner family impact


    Parents in 37% bracket, child with $15,000 investment income:


    Old system:** ($15,000 - $2,650) × 37% = **$4,570 kiddie tax

    New system:** Child's total income determines rate, likely 10-12% = **$1,200-1,500 kiddie tax

    Annual savings: $3,000-3,400


    New wealth transfer strategies


    Revitalized strategies:

  • Custodial accounts (UTMA/UGMA) — No longer toxic for high earners
  • Gifting appreciating assets to children before gains are realized
  • Income-producing assets in children's names (rental properties, businesses)
  • Family limited partnerships with children as limited partners

  • Timing considerations:

  • Bunch gains in children's low-income years (under 18, before substantial earned income)
  • Coordinate with college financial aid — student assets still face higher assessment rates
  • Consider Roth IRA conversions for children with unearned income

  • Key takeaway: High-income families can now save thousands annually through strategic income shifting to children, as the punitive parent-rate kiddie tax has been eliminated for 2026.

    Key Takeaway: High-income parents can now save $3,000-4,000+ annually per child through strategic income shifting, as children's unearned income is no longer taxed at the parent's high marginal rates.

    Family business implications of kiddie tax changes


    The kiddie tax changes create new opportunities for family business owners to involve children as owners or partners while minimizing the tax burden on business distributions.


    S-Corporation ownership structures


    Previous problem: If your child owned S-corp stock and received distributions, any amount over $2,650 faced kiddie tax at your marginal rate.


    2026 solution: Distributions are now taxed at the child's rate, making minority ownership gifts much more attractive.


    Example: Child owns 5% of family S-corp worth $2 million

  • Annual distribution: $25,000
  • Old kiddie tax (parents in 32% bracket): $7,152
  • New kiddie tax (child's 12% bracket): $2,736
  • Annual savings: $4,416

  • Family limited partnership opportunities


    Revitalized strategy: Gifting limited partnership interests to children

  • Partnership income over $2,800 taxed at child's rate
  • Valuation discounts still apply for gift tax purposes
  • No more penalty of parent-rate taxation on distributions

  • Key considerations:

  • Earned vs. unearned income classification — management fees to children are earned income (not subject to kiddie tax)
  • Reasonable compensation requirements — children performing services must receive reasonable pay
  • Gift tax annual exclusions — $18,000 per child per year (2026)

  • Key takeaway: Family business owners can now structure children's ownership interests without the punitive kiddie tax at parent rates, making succession planning and wealth transfer strategies significantly more attractive.

    Key Takeaway: Business owners can now gift ownership interests to children without facing punitive parent-rate taxation on business income, making family succession planning much more tax-efficient.
