How Grandparents Can Use Custodial Roth IRAs to Help Build Multigenerational Wealth
At BDB Wealth Advisors, we often work with families and grandparents who are looking for tax-efficient ways to support the next generation while maintaining flexibility in their overall financial plan.
Grandparents often want to help their grandchildren financially. Some contribute to 529 plans, some give cash gifts, and others help with education expenses. But one strategy that is sometimes overlooked is the custodial Roth IRA.
A custodial Roth IRA can be a valuable way to help a child or grandchild begin investing early, build strong financial habits, and create the potential for decades of tax-advantaged growth.
The key requirement is simple but important:
The child must have earned income.
That means a grandchild generally cannot contribute to a Roth IRA simply because a grandparent wants to make a gift. The child must have income from work, such as wages from a job, babysitting, lawn care, working in a family business, or other legitimate earned income.
Income limits and eligibility rules for Roth IRA contributions can apply at higher income levels, though they are typically not a limiting factor for minors with earned income.
For families just beginning to organize their finances, it can be helpful to first focus on the broader financial plan before layering in more advanced strategies like custodial Roth IRAs. You may also find it helpful to read Why a Financial Plan Is More Than Just Investments.
What Is a Custodial Roth IRA?
A custodial Roth IRA is a Roth IRA opened for a minor and managed by an adult custodian, typically a parent or guardian, until the child reaches the age of majority.
The account belongs to the child, but the custodian manages the investments. Once the child reaches the required age, control of the account transfers fully to them.
Qualified withdrawals from a Roth IRA are generally federal income tax-free, provided the account has been open for at least five years and other IRS requirements are met.
Why Grandparents Are Interested in This Strategy
A custodial Roth IRA can be especially attractive because children are often in very low tax brackets.
Roth IRA contributions are made with after-tax dollars, but qualified withdrawals in retirement may be tax-free if IRS requirements are met. That creates a meaningful long-term opportunity:
A small contribution made early in life may have many years to compound.
For example, a teenager who contributes a few thousand dollars from part-time work and leaves it invested long term may benefit significantly from compounding over time.
This type of long-term thinking is similar to decisions families face when deciding whether to pay off a mortgage before retirement. Early choices can have a lasting impact on financial outcomes.
Can Grandparents Fund the Roth IRA?
Yes, but with an important limitation.
A grandparent can gift money to help fund a custodial Roth IRA, but:
Contributions to a Roth IRA for a minor are generally limited to the lesser of the child’s earned income for the year or the annual IRA contribution limit. For 2026, that limit is $7,500 per individual.
Proper documentation of earned income is important, especially for self-employment or informal work.
What Can the Money Be Used For?
Roth IRAs are primarily designed for retirement, but they offer flexibility.
Contributions can generally be withdrawn tax- and penalty-free
Earnings may be withdrawn under certain conditions, but taxes and penalties may apply if distribution rules are not met
Families often do not realize how financial decisions today can affect long-term stability. For example, planning considerations discussed in What Happens Financially When a Spouse Passes Away? highlight how early preparation can make a meaningful difference later in life.
What Can Be Invested Inside a Custodial Roth IRA?
Depending on the custodian, a custodial Roth IRA may include:
Low-cost ETFs
Diversified mutual funds
Individual stocks
Bond funds
Target-date portfolios
At BDB Wealth Advisors, investment strategies should be considered in light of the time horizon, risk tolerance, and purpose of the account. For younger investors with long time horizons, a growth-oriented approach is often considered, but always within the context of the broader financial plan.
Custodial Roth IRA vs. 529 Plan
A custodial Roth IRA is not a replacement for a 529 plan. They serve different purposes.
529 plans are designed primarily for education expenses
Roth IRAs are designed primarily for retirement
For many families, the most effective approach is not choosing one over the other, but using both strategically.
For additional education planning ideas, see Beyond the 529: Flexible Education Planning Strategies.
How 529 Plans and Roth IRAs Can Work Together
One of the biggest concerns families historically had with 529 plans was:
What if the funds are not fully used for education?
Recent changes under the SECURE 2.0 Act introduced new flexibility.
529-to-Roth IRA Rollover Opportunity
Unused 529 plan funds may now be rolled into a Roth IRA for the beneficiary, subject to several important rules.
This creates a compelling multigenerational planning strategy:
Fund education through a 529 plan
If funds remain, redirect a portion into retirement savings
Help build long-term financial security
Key Rules to Understand
A lifetime maximum of $35,000 per beneficiary can be rolled from a 529 plan into a Roth IRA
Rollovers are subject to annual Roth IRA contribution limits (e.g., generally $7,500 per year)
The beneficiary must have earned income at least equal to the rollover amount
The 529 plan must have been open for at least 15 years
Contributions (and associated earnings) made within the last 5 years are generally not eligible
Rollovers must be made directly from the 529 plan to a Roth IRA in the beneficiary’s name
Why This Matters for Grandparents
This rule significantly reduces one of the major concerns around overfunding a 529 plan.
Instead of worrying about unused funds being locked into education-only use, families now have more flexibility.
This type of long-term planning often overlaps with broader estate considerations, including strategies discussed in 2026 Estate Planning Guide: Wills, Trusts, Powers of Attorney & More.
How BDB Wealth Advisors Can Help
BDB Wealth Advisors works with families to evaluate how custodial Roth IRAs and 529 plans may fit into a broader financial strategy.
This type of planning often intersects with major life transitions, including career changes and retirement preparation. For example, families navigating more complex financial decisions may benefit from guidance similar to what we outline in Transitioning to Civilian Life: A Financial Checklist for Veterans.
Our goal is not just to open accounts, but to help build a coordinated plan that evolves over time.
Important Considerations
The child must have legitimate earned income
Contributions cannot exceed earned income or the applicable annual IRA limit
The account becomes the child’s at the age of majority
Early withdrawals may reduce long-term growth
Tax and reporting rules may apply
529 rollover rules must be followed carefully
Investing involves risk, including possible loss of principal
Considering This Strategy for Your Family?
Every family situation is different. Factors like earned income, tax considerations, education planning, and long-term goals all play a role in determining whether a custodial Roth IRA or 529 plan strategy may be appropriate.
If you’re exploring ways to support your children or grandchildren while staying aligned with your overall financial plan, it may be helpful to have a conversation and evaluate your options in a structured way.
Frequently Asked Questions
Can grandparents contribute directly to a Roth IRA for a grandchild?
They can gift funds to help support the contribution, but the child must have earned income to support the amount contributed.
What happens if a 529 plan is not fully used?
Unused funds may be eligible for a Roth IRA rollover, subject to IRS rules and limits.
Does a child need a job to open a Roth IRA?
Yes, the child must have earned income from legitimate work in order to make a Roth IRA contribution.
Is a custodial Roth IRA better than a 529 plan?
Not necessarily. They are designed for different purposes. A 529 plan is generally focused on education, while a Roth IRA is generally focused on retirement. In many cases, both can be used strategically.
What is one of the biggest downsides of a custodial Roth IRA?
One important consideration is that the account ultimately belongs to the child. Once they reach the age of majority, they control how the account is used.
Final Thoughts
A custodial Roth IRA can be one of the most meaningful financial gifts a grandparent gives, not because of the initial contribution alone, but because of the time and compounding it allows.
When combined with thoughtful 529 planning, families can create a flexible strategy that supports:
Education
Early investing habits
Long-term retirement savings
Multigenerational wealth planning
Wealth is often built over time through consistency, discipline, and a long-term perspective. Many of these same principles are reflected in broader financial planning topics, including how families approach long-term decisions around retirement, estate planning, and financial structure.
