Understanding the Basics
Kiddie tax rules prevent parents from shifting investment income to children in lower brackets. Understanding these rules helps with education savings and family tax planning.
Key Considerations

- Under 18; age 18 and certain students ages 19-23 have additional earned-income support tests.
- Unearned income can include interest, dividends and gains; filing and deduction rules differ.
- Compare eligible Roth contributions and qualified 529 distributions; neither is universally best.

Frequently Asked Questions
What is the kiddie tax?
For 2026, more than $2,700 of unearned income can trigger Form 8615 if the other tests apply. It compares the parent-based calculation with the child's own tax; qualified dividends and net capital gains retain applicable preferential-rate treatment.
At what age does kiddie tax end?
At year-end: under 18; or age 18 with earned income no more than half of support; or a full-time student age 19-23 with earned income no more than half of support. Further conditions appear on page 4. Sources: IRS Form 8615 instructions; IRS Revenue Procedure 2025-32 (2026 amounts).

Tax planning can help manage your lifetime tax burden. Roth conversions, withdrawal sequencing and tax-loss harvesting can help save taxes over time, depending on your individual circumstances.
How Do Different Strategies Compare?
Traditional IRA / 401(k): Withdrawals are generally taxable except for after-tax basis. RMD timing depends on birth year and account type; certain current-employer plans permit retirement deferral, with exceptions. Roth IRA / Roth 401(k): Qualified withdrawals are tax-free. Neither requires lifetime RMDs for the owner; beneficiary rules differ.
Taxable brokerage: Income and realized gains may be taxable; withdrawals are not all taxed at capital-gains rates.
HSA: Qualified medical withdrawals are tax-free. Other withdrawals may be taxable and subject to additional tax. Withdrawal order depends on your circumstances; no sequence is best for everyone.
What Tax Planning Actions Should You Prioritize?
Effective tax planning requires proactive strategies implemented throughout the year, not just during tax season. Consider these priority actions:
- Review your withholding and estimated payments: The IRS Tax Withholding Estimator can help you determine if your current withholding is appropriate to avoid surprises at tax time.
- Evaluate Roth conversion opportunities: Compare current and potential future taxes. The taxable portion of a conversion is income; qualified Roth distributions are tax-free. Review the amount and withdrawal rules with your tax advisor.
- Harvest tax losses: Review whether selling investments at a loss to offset gains fits your circumstances and applicable tax rules.
- Review retirement contributions: Pre-tax workplace contributions may reduce taxable wages. IRA deductibility depends on eligibility, income and workplace-plan coverage. Roth contributions are not deductible.
- Review charitable giving: Discuss whether bunching donations or using a donor-advised fund fits your goals. Deductibility depends on eligibility, limits and whether you itemize.
Effective tax planning can help individuals and families identify opportunities to reduce their tax burden and improve after-tax outcomes.
How to Create a Tax-Efficient Retirement Plan: Step-by-Step
Implementing a tax-smart strategy requires a systematic approach:
- 1. Step 1: Map your income sources. Identify all current and projected retirement income streams, including Social Security, pensions, 401(k)/IRA distributions, and taxable investment income.
- 2. Step 2: Estimate your future tax bracket. Project your retirement income to determine which federal and state tax brackets you will likely fall into, using resources from the IRS.
- 3. Step 3: Evaluate Roth conversions. Compare the taxable conversion amount, available funds to pay taxes and potential future tax treatment. Savings are not assured.
- 4. Step 4: Evaluate tax-loss harvesting. Review whether realizing investment losses fits your circumstances and applicable tax rules with your tax advisor.
- 5. Step 5: Plan withdrawals. Compare account tax treatment, required distributions, cash needs and other circumstances. There is no single withdrawal order appropriate for everyone.
- 6. Step 6: Review charitable options. Ask your tax advisor whether you qualify for a direct IRA-to-charity distribution and how its rules and limits apply to any required distribution.
- 7. Step 7: Review annually with your advisors. An annual review helps support informed decisions as tax laws and circumstances change; it cannot assure savings or prevent every mistake.
Tax-efficient retirement planning may help reduce the taxes you pay throughout retirement, depending on your individual circumstances. Book your tax strategy session.

Kiddie Tax Conditions and Savings Accounts (2026) In addition to the age/support tests on page 2, the child must be required to file a tax return, have at least one living parent at year-end, and not file a joint return. Full-time student generally means enrolled full time during part of at least five calendar months. Special January 1 birthday rules apply. Support is not the same as earned income; apply the Form 8615 definitions, including scholarship exclusions where applicable. For a dependent in 2026, the basic standard deduction generally is the greater of $1,350 or earned income plus $450, capped at the regular deduction for the filing status. This is separate from the $2,700 kiddie-tax threshold. Income mix and other filing requirements matter; unearned income is not simply tax-free up to $2,700. Roth IRA contributions are limited by eligible compensation, annual limits and income eligibility. Qualified Roth distributions are tax-free; nonqualified withdrawals can have tax consequences. Qualified 529 distributions are tax-free only within eligible expense and coordination limits; nonqualified earnings may be taxable and face additional tax. Contributions do not create a federal deduction.
