If this is new territory for you, you're not alone. Most people don't hear about custodial Roth IRAs until their kids are already in their twenties and the compounding window has narrowed considerably. The good news is that if your child earns any income at all – from babysitting, a summer job, or a small side gig – the door is open right now.
What a Roth IRA Actually Is
A Roth IRA is a retirement savings account that you fund with money you've already paid income tax on. You don't get a deduction upfront the way you do with a traditional IRA or 401k, but the trade-off is significant: the money inside the account grows completely tax-free, and when your child eventually withdraws it in retirement, they pay no taxes on any of it – not on the contributions, and not on the decades of growth.
For adults who open Roth IRAs later in life, the benefit is real but limited by time. For a child who opens one at 10, 12, or 15, the benefit is almost difficult to overstate. Every dollar contributed at a young age has 50 or 60 years to compound before it's needed. A $1,000 contribution made at age 10, earning an average 8% annual return, becomes roughly $46,000 by age 70. That's not a typo. That's how compound growth works when you give it enough time.
The Custodial Roth IRA: How It Works for Kids
Children can't open financial accounts in their own names, but a parent or guardian can open a custodial Roth IRA on their behalf. The adult manages the account until the child reaches the age of majority in their state – typically 18 or 21 – at which point the account transfers fully into the child's control.
The eligibility requirement is the same as for adults: the child must have earned income. Earned income means money from actual work – wages from a part-time job, babysitting payments, lawn mowing, dog walking, or any legitimate paid work. Allowance doesn't count, nor do gifts or investment income. The contribution limit is the lower of the IRS annual maximum (currently $7,000 for 2024) or the child's actual earned income for the year. So if your child earned $800 babysitting, you can contribute up to $800 to their Roth IRA – and importantly, that money can come from you. The child doesn't have to put their own earnings in; they just have to have earned that amount.
The Real Benefit: What Time Does to Money
The most compelling reason to open a custodial Roth IRA has nothing to do with tax strategy and everything to do with time. Compound growth is genuinely one of the most powerful forces in personal finance, and children have more of it than anyone.
Consider a straightforward example. A parent contributes $3,000 per year to a custodial Roth IRA from the time their child is 8 until they're 18 – ten years of contributions, then nothing. Assuming an average 7% annual return, that account grows to roughly $380,000 by the time the child turns 65. The total amount contributed was $30,000. The rest – over $350,000 – came from time and compounding, and none of it will be taxed in retirement. Starting even five years later changes the outcome dramatically. This is why financial educators consistently say the best time to start is as early as possible, and the second best time is right now.
Should You Open One? Questions Worth Sitting With
Before opening an account, it's worth thinking through a few things honestly, because this decision involves both the practicalities of finance and the more personal question of what you want your child's relationship with money to look like.
Does your child have earned income? This is the non-negotiable starting point. If they have a part-time job, do occasional paid work, or even help with a family business for documented pay, they qualify. If not, the account simply isn't available to them yet.
Is your own financial foundation stable? This is an important one. A custodial Roth IRA for your child is a beautiful long-term gift, but it shouldn't come at the expense of your own emergency fund, retirement savings, or high-interest debt repayment. Your financial stability is also your child's stability. There's no rush to start if the timing isn't right for your household.
What do you want your child to understand about this? The account doesn't have to be a secret that appears magically at 18. Many parents use it as a teaching tool – showing their child how the account grows over time, explaining what compound interest is in simple terms, and connecting the dots between work, saving, and long-term security. That conversation, repeated over years, can shape a child's relationship with money in lasting ways.
How to Open a Custodial Roth IRA
The process is simpler than most people expect. Major brokerages – Fidelity, Vanguard, Charles Schwab, and others – all offer custodial Roth IRA accounts with no minimum balance requirements and no monthly fees. You'll need your own information as the custodian, your child's Social Security number, and documentation of their earned income if you want to be thorough about record-keeping.
Once the account is open, you can invest the contributions in index funds – low-cost funds that track the broad market and have historically returned around 7–10% annually over long periods. For a child's account with a 50+ year horizon, broad market index funds are a straightforward and widely recommended choice. You don't need to actively manage the investments. The strategy is simple: contribute when possible, invest in a low-cost index fund, and let time do the rest.
A Few Things to Be Aware Of
The flexibility of a Roth IRA is one of its greatest strengths. Contributions (but not earnings) can be withdrawn at any time without penalty. So if your child faces a genuine financial hardship at 25, they can access the money they put in without owing taxes or early withdrawal penalties. The earnings stay locked in for retirement purposes, but the contributions are always accessible. This makes it a less rigid vehicle than many people assume.
One thing to keep in mind: if your child earns very little in a given year, that's the ceiling for their contribution. You can't contribute $5,000 to their account if they only earned $400. Track their earned income and stay within that limit to remain compliant with IRS rules.
Also worth knowing – the account doesn't affect college financial aid calculations the same way a regular savings account might, particularly while it's under the parent's custodial control. Once the child takes ownership of the account, its treatment in financial aid calculations can vary, so it's worth speaking with a financial advisor if college funding is part of your planning.
The Quiet Gift of Starting Early
There's something meaningful about the act of opening a Roth IRA for a child that goes beyond the numbers. It's a decision made entirely in their interest, with no immediate benefit to you, that requires patience and a long view. It says, quietly, that you believe in their future and you're doing something concrete to protect it.
It also opens a conversation – or many conversations over many years – about money, work, saving, and time. Those conversations are their own kind of inheritance. A child who grows up watching a retirement account accumulate, who understands what compound growth means before they graduate high school, enters adulthood with a foundation most people spend decades trying to build from scratch.
You don't have to contribute the maximum every year. You don't have to start with a large amount. Starting with what you have, when you have it, is enough. The account will do the rest.
FAQ
Can I open a Roth IRA for my child if they don't have a job? Not yet. The IRS requires that contributions come from earned income – money from actual work. Once your child has any form of legitimate paid employment, including informal work like babysitting or lawn care with documented payments, they become eligible.
Do I have to use my child's own earnings to fund the account? No. The rule is that the contribution cannot exceed your child's earned income for the year – but the money itself can come from you. If your child earns $1,500 from a summer job and wants to keep it, you can contribute up to $1,500 to their Roth IRA from your own funds as a gift.
What happens to the account when my child turns 18? The custodial relationship ends and the account transfers entirely into your child's name. They take full control of how it's managed and invested, though the Roth IRA rules still apply to withdrawals.
Is a Roth IRA better than a 529 college savings plan? They serve different purposes. A 529 is specifically designed for education expenses and offers tax advantages tied to that use. A Roth IRA is for retirement but offers more flexibility. Some families use both; others prioritize one depending on their goals. A financial advisor can help you think through the right balance for your situation.
What if my child's earned income is very small – is it still worth it? Yes. Even small contributions made early have significant time to grow. A $500 contribution at age 12 earning 7% annually is worth over $15,000 by age 65. Start with whatever is realistic. Consistency over decades matters far more than amount.
