Custodial Roth IRA for Minor Children with Earned Income in 2026

The custodial Roth IRA is one of the most powerful long term wealth tools available to families with children who earn money, and the brokerage industry finally caught up to the demand in 2025 with most major platforms now offering streamlined account opening. The 2026 contribution limit for a Roth IRA is $7,000 for individuals under 50, but the practical limit for a child is the lesser of $7,000 or the child earned income for the year. A 12 year old who earned $4,800 dog walking and yard work can have $4,800 contributed to a custodial Roth IRA in their name, with the parent or guardian as custodian until age 18 or 21 depending on state law.

The earned income requirement is the hinge that makes the strategy work. The IRS requires income from work, which means W-2 wages, self employment, or farm income. Allowance, gifts, investment income, and inheritance do not qualify. For self employed minors, the most common income sources that qualify include lawn care, pet sitting, babysitting, social media content creation paid through 1099 channels, modeling, acting, sports officiating, tutoring, music lessons, and product sales. The child does not need to file a tax return unless self employment income exceeds $400 or W-2 income exceeds the standard deduction of $15,000 for 2026.

Documentation is critical because the IRS does scrutinize custodial Roth contributions in audits. The recommended practice is a contemporaneous earnings log that records date, hours worked, hourly rate, payor, and service provided. For self employment income, an annual Schedule C should be prepared even if not required for filing because it formalizes the income and creates an audit defense file. The total annual contribution to the Roth IRA should not exceed the documented earned income for the year. Parents should pay the child by check or transfer rather than cash where possible to create a paper trail.

The math compounds dramatically over a 50 plus year horizon. A single $7,000 contribution at age 12 invested in a low cost broad market index fund returning a long term real 7 percent grows to roughly $235,000 by age 65 in inflation adjusted dollars. Continued $7,000 annual contributions through age 22 produce roughly $2.1 million by age 65 in inflation adjusted terms. The contributions can always be withdrawn tax and penalty free which gives the child meaningful financial flexibility for major life expenses including college, first home down payment, and business capitalization. Earnings withdrawn before 59 and a half are subject to a 10 percent penalty unless an exception applies.

The 2026 IRS first time homebuyer exception allows up to $10,000 of earnings to be withdrawn penalty free for the purchase of a first home. The qualified higher education expenses exception allows penalty free withdrawal of earnings for tuition, fees, books, supplies, and required equipment at an eligible educational institution. For the child whose Roth IRA is large enough by age 25 to support a meaningful down payment, the combination of contribution withdrawal flexibility and the first home exception means the account can serve double duty as retirement and house fund.

Account opening process at the major brokers improved meaningfully in 2025 and 2026. Fidelity Custodial Roth IRA opens in about 12 minutes online with no minimum balance and zero account fees. Schwab opened its custodial Roth IRA platform in March 2026 with similar parameters. Vanguard requires a paper application and a $1,000 minimum, which limits its appeal for small accounts. ETrade and Interactive Brokers offer custodial Roth IRA accounts but with steeper interface complexity. Robinhood does not offer custodial accounts as of April 2026.

Investment selection inside the custodial Roth IRA should focus on broad low cost index funds. The simplest portfolio is a single fund holding like Vanguard Total Stock Market ETF VTI at 0.03 percent expense ratio or Vanguard Total World Stock ETF VT at 0.07 percent. Target date funds at Fidelity, Vanguard, and Schwab provide built in diversification and rebalancing for hands off accounts. The custodian should not engage in single stock picking or short term trading inside a child Roth, both because of execution risk and because of the tax treatment differences with the long term wealth building purpose of the account.

Custodianship transition timing varies by state law. Most states transfer the account to the beneficiary at age 21 under the Uniform Transfers to Minors Act, while California Tennessee and several others allow the custodian to specify age 18 or age 25 at account opening. Once the account transfers, the now adult beneficiary has full control of contributions, withdrawals, and investment decisions. Parents who want to maintain influence over the long term direction of the account often pair the custodial Roth with explicit conversation about long term wealth building and a documented household financial plan that gives the young adult context for the decisions ahead.

The estate planning benefits of custodial Roth IRAs are also meaningful. The account passes outside probate to the named beneficiary upon the original account holder death. The decade following the SECURE Act 2.0 modifications has clarified that inherited Roth IRAs from non spouse parents must be fully distributed by the end of the 10th year following the death, but no required minimum distributions are required during years one through nine. For families building multi generational wealth, the custodial Roth IRA at the youngest layer compounds for the longest possible time horizon and remains the most tax favored long term vehicle in the US tax code.
