The most powerful thing you can do to set your child up financially is start early, even with small amounts. Time is the single biggest advantage a child has, and a dollar invested when your kid is two years old has decades to compound before they need it. The specific tools available to you depend on your child’s age and your goals, but the best strategies combine tax-advantaged accounts, early credit building, and hands-on financial education.
Open a 529 Plan Early
A 529 plan is a state-sponsored investment account where your contributions grow tax-free as long as the money is eventually used for qualified education expenses. That includes tuition, room and board, books, and up to $10,000 per year for K-12 private school tuition. You can open one the day your child is born, and there’s no income limit for contributors.
One concern parents have is overfunding a 529 if their child doesn’t attend college or earns scholarships. Starting in 2024, federal law allows you to roll unused 529 funds into a Roth IRA for the same beneficiary. The lifetime cap on these rollovers is $35,000, the 529 account must have been open for at least 15 years, and only contributions that have been in the account for at least five years qualify. Each year’s rollover is also capped at the annual Roth IRA contribution limit ($7,500 for 2026), so you’d need several years to move the full $35,000. This flexibility makes a 529 a much safer bet than it used to be.
You can also change the beneficiary on a 529 to a sibling, cousin, or even yourself if your child doesn’t need the money. Between the Roth rollover option and beneficiary changes, the risk of “wasting” 529 money is low.
Start a Custodial Roth IRA
If your child has any earned income, they’re eligible for a custodial Roth IRA. This is a retirement account you manage on their behalf until they reach adulthood. The money grows completely tax-free, and because your child likely has little or no other income, they’ll pay zero tax on the contributions going in.
The key requirement is that your child must have legitimate earned income. That can come from wages, self-employment, tips, or commissions. Babysitting, lawn mowing, tutoring, acting, or working at a family business all count. The contribution limit for 2026 is the lesser of $7,500 or 100% of the child’s earned income for the year. If your teenager earns $3,000 from a summer job, the maximum contribution is $3,000.
Here’s where the math gets exciting. If you contribute $3,000 a year from age 15 to 18, and that money grows at a historical average stock market return, your child could have roughly $200,000 to $300,000 by age 60 without adding another dollar. The earlier you start, the more dramatic the compounding. You’re allowed to give your child the money to fund the contribution, as long as they actually earned at least that much during the year.
Use Gift Tax Rules to Transfer Wealth
You can give your child up to $19,000 per year (the 2026 limit) without filing a gift tax return. If you’re married, both parents can each give $19,000, meaning $38,000 per year to a single child with zero paperwork. Grandparents can do the same.
These gifts can fund a brokerage account, a savings account, a 529 plan, or anything else. Amounts above the annual exclusion count against your lifetime gift tax exemption, which is $15,000,000 per person for 2026. For most families, the annual exclusion is more than enough to transfer meaningful sums over a child’s first 18 years without any tax consequences.
Consider a Custodial Brokerage Account
UGMA and UTMA accounts are custodial brokerage accounts that let you invest on behalf of a minor. You manage the account until your child reaches the age of majority (18 or 21, depending on your state), at which point the money becomes legally theirs with no restrictions on how they spend it.
The flexibility is both the advantage and the risk. Unlike a 529, there are no rules about using the money for education. Your child could use it for a car, a business, a down payment, or anything else. But you can’t take the money back, and your child gains full control at a young age whether or not they’re ready.
There’s also a financial aid consideration. UGMA and UTMA accounts are assessed as the student’s asset on the FAFSA, meaning 20% of the balance counts against financial aid eligibility each year. Parent-owned assets like 529 plans are assessed at only 5.64%. A $50,000 custodial account would reduce aid eligibility by $10,000, while the same amount in a parent-owned 529 would reduce it by about $2,820. If your child will apply for financial aid, this difference matters.
Build Their Credit Before They Need It
Adding your child as an authorized user on one of your credit cards gives them a credit history before they ever apply for a card of their own. Several major issuers have no minimum age requirement, while others set the floor at 13, 15, or 16. You don’t need to give your child the physical card for them to benefit. Simply being listed on an account with a long history and low utilization helps build their credit profile.
By the time your child turns 18 and applies for their first card, apartment lease, or auto loan, they could already have years of positive credit history. A strong credit score at 18 means lower interest rates and better approval odds on everything from student loans to that first apartment deposit. Pick a card with no annual fee, keep the balance low relative to the credit limit, and pay it off every month.
Open a High-Yield Savings Account Together
A simple savings account in your child’s name (or a joint account you manage together) serves a dual purpose. It’s a safe place for birthday money, allowance, and earnings, and it’s a teaching tool. When your child can log in and watch their balance grow from interest, the concept of “money making money” becomes real in a way no lecture can achieve.
Many online banks offer high-yield savings accounts with no minimum balance and no monthly fees. The interest won’t build wealth on its own, but the habit of saving regularly and watching money accumulate builds a financial mindset that compounds over a lifetime.
Teach Money Skills at Every Age
Accounts and investments give your child a financial head start, but financial literacy determines whether they keep it. The approach should evolve as your child grows.
- Ages 3 to 5: Introduce the concept of exchanging money for things. Let them hand cash to a cashier. Use clear jars labeled “save,” “spend,” and “give” so they can physically see money being divided.
- Ages 6 to 10: Start an allowance tied to household responsibilities. Introduce the idea of saving for a goal, like a toy that costs more than one week’s allowance. Let them experience the disappointment of spending money on something they later regret.
- Ages 11 to 14: Open a bank account with them and show them how interest works. Talk about how advertising tries to influence spending decisions. Introduce the basics of investing using real examples from a custodial account.
- Ages 15 to 18: Help them earn income and file a tax return. Walk them through a basic budget. Show them their credit report if you’ve added them as an authorized user. Explain student loans, compound interest, and the cost of debt before they head to college.
The specific dollar amounts you invest matter less than consistency and education. A child who enters adulthood with a funded Roth IRA, a credit score, a basic understanding of budgeting, and the habit of saving has an enormous advantage over peers who are starting from zero.
