529 Plans, Custodial Accounts, and Minor Trusts: The Best Gifts You Can’t Wrap

By Team Seneschal

You want to give your child or grandchild something that lasts. You want a gift that builds confidence, expands choices, and creates opportunities. You can do that with a financial gift designed to grow with them. These gifts don’t come in a box. They come with long-term impact.

Three tools stand out. A 529 plan. A custodial account. A minor trust. Each one helps you invest in a child’s future uniquely. Each one comes with trade-offs that matter.

529 Plans

A 529 plan is built for education. Money in a 529 plan grows tax-free when used for qualified education expenses. Those expenses include tuition, books, fees, and even some room and board. Federal law allows for the limited use of 529 funds for K-12 tuition and registered apprenticeship programs, although some states don’t follow these rules and may treat those withdrawals differently.

You stay in control. You decide how the money is invested. You choose when distributions happen. The child is the beneficiary, not the owner. That means they cannot force a withdrawal later.

You can also change the beneficiary to another family member if plans shift. Families use this flexibility when one child doesn’t need the funds or gets a scholarship.

A 529 plan works best when your primary goal is education. It also works well if you want substantial tax benefits and hold the investment for an extended period.

Custodial Accounts

A custodial account works differently. These accounts include the Uniform Gifts to Minors Act and the Uniform Transfers to Minors Act. You can open an account at most financial institutions.

You control the account only until the child reaches the age of majority. Then the account becomes theirs. That’s a significant difference from a 529 plan. They can use the assets for anything. College. A car. A business idea. Even choices you might not support.

Custodial accounts offer some tax benefits. A portion of the account’s unearned income is taxed at the child’s rate, which is usually lower. Once unearned income passes the annual kiddie tax threshold, the remaining income is taxed at the parent’s marginal rate. That makes it crucial to consider investment earnings when funding these accounts.

A custodial account works best when you want flexibility. It can be used for any expense that benefits the child. It’s also a simple way to transfer assets without the need for a trust structure.

Minor Trusts

Families who want more control often consider minor trusts. These trusts hold assets for a child under terms you set. You decide when they receive access. You choose how funds can be used. You appoint a trustee to manage and distribute assets.

Minor trusts take different forms. Some families use a Section 2503(c) trust. Others use a more flexible irrevocable trust. The right structure depends on your goals.

Trusts come with more complexity. They require legal drafting and ongoing administration. They also offer more protection. You can delay access until adulthood or even later. You can place guardrails around spending. You can protect assets from creditors in some cases.

A minor trust is best suited for those seeking a long-term structure. It also works well when you expect to gift larger amounts or want strict control over timing and use.

How to Choose

Your goals guide your choice. If education is the focus, a 529 plan is often the strongest fit. If you want broad flexibility with fewer rules, a custodial account may be enough. If you want long-term control or plan to gift significant amounts, a trust provides the necessary structure.

The child’s age matters. The earlier you start, the more compounding works in your favor. Your tax situation also matters. Your comfort with the child taking control at the age of majority also matters.

You can mix and match. Families often use a 529 plan for education and a custodial account for general needs. Others use a trust as the primary vehicle and add a 529 plan to cover tuition expenses. You don’t have to choose just one.

The Impact Grows Over Time

You’re not just giving money. You’re expanding choices. You’re giving a young person the freedom to pursue education, start a business, explore interests, or step into adulthood with less financial stress.

A thoughtful plan today becomes a lifelong advantage. It also becomes a message. It tells the child that you believe in their future.
