Understanding IRS Form 8818: Dual Filing for Children's Investment Income
Optional election to report a child's unearned income on parents' return instead of filing separately.
Who Qualifies for Dual Filing?
- Age requirements: Under 19 (or under 24 if full-time student)
- Income limits: Only unearned income between $1,100-$11,000 (2024)
- Filing status: Parents must file jointly if married
- No self-employment: Child cannot have earned income
Available only if child would otherwise need to file Form 8615.
Key Benefits vs. Drawbacks
| Advantages | Considerations |
|---|---|
| Eliminates separate filing for child | May increase parents' AGI for other tax benefits |
| Simplifies tax preparation | Could phase out parents' deductions/credits |
| Single tax payment | Permanently forfeits child's standard deduction |
Election Requirements
- Parental consent: Both parents must sign if filing jointly
- Irrevocable choice: Cannot undo after filing deadline
- Documentation: Must attach all child's 1099 forms
- Thresholds: Cannot use if child has $11,000+ unearned income
When to Avoid This Election
- Parents are in highest tax bracket (37%)
- Family receives ACA subsidies or education credits
- Child has capital losses to carry forward
- Parents are subject to Net Investment Income Tax
Incorrect elections can cost thousands in lost tax benefits.
Alternative Strategies
- Direct filing: Child files separately with Form 8615
- Trust allocation: Using trust tax rates instead
- Income shifting: Gifting appreciating assets
