UTMA vs UGMA vs 529: What Each One Is Actually For

UGMA and UTMA are both custodial accounts — the federal aid handbook describes them as a way to set up an account “for gifts of cash and financial assets for a minor without the expense of creating a trust” (FSA Handbook 2026–27, fsapartners.ed.gov, checked September 2026). The practical difference that shows up in this post is the age the account ends, which the table below gives for both. A 529 is a different thing: a tax-advantaged education account under section 529 of the Internal Revenue Code.

Whose money is it?

A UTMA or UGMA belongs to the child from the first deposit. Fidelity’s custodial account guide puts it plainly: “Money put into a custodial account is an irrevocable gift to the child,” and contributions “cannot be withdrawn by a parent or guardian (unless it’s for the benefit of the child)” (fidelity.com, checked September 2026). You manage it as custodian. You do not own it.

A 529 belongs to the account owner. In an individually owned 529, “an adult individual, usually a parent or grandparent, is the account owner,” and “the account owner makes investment decisions” (savingforcollege.com, checked September 2026). The child is the beneficiary. The owner can change the beneficiary to another member of the family without it counting as a distribution (26 U.S.C. §529(c)(3)(C)(ii), law.cornell.edu, checked September 2026).

One hybrid exists: a custodial 529, funded from UTMA/UGMA money. At the age of majority “the beneficiary can take over control of the account” (savingforcollege.com, checked September 2026).

When does the child take control? State by state

21 in 41 of 51 jurisdictions. 18 in nine. 22 in one. That is the default age at which a UTMA custodian has to hand the account over, counted across the 50 states and DC:

Older UGMA accounts end earlier: 18 in 48 jurisdictions, 19 in Alabama and Nebraska, 21 in Mississippi (51 − 2 − 1 = 48). Twenty-two jurisdictions list an option or exception to the default — usually a different age the transferor can choose — and those are in the last column.

Source: finaid.org’s UGMA/UTMA age-of-termination table (checked September 2026). Three outliers were checked against the statute itself, September 2026:

• California (Probate Code §3920.5, leginfo.legislature.ca.gov): 18 by default; a gift can specify up to 21, and a will or trust up to 25.
• Louisiana (Act 60 of 2023, legis.la.gov): amended R.S. 9:751 and 9:770 so that “minor” means under twenty-two and the custodian transfers the property at twenty-two, replacing eighteen.
• Florida (§710.123, flsenate.gov): 21 for gifts and transfers by will or trust, extendable to 25 — but with an extension the minor has “the absolute right to compel immediate distribution of the entire custodial property when the minor attains 21,” unless the transferor’s notice process removes it. Property transferred under §710.107 or §710.108 ends at 18.

Florida shows why the table is a default, not a guarantee: the age can depend on how the property reached the account. Confirm the age in your own state’s UTMA statute before relying on it. Once the account transfers, Fidelity notes, “the child can use them for any purpose” (fidelity.com, checked September 2026).

What it does to financial aid, in dollars

The federal Student Aid Index (SAI) for a dependent student counts the two accounts in different places, and at different rates.

UTMA/UGMA: 20% of the balance. The handbook: “Because the minor is the owner of the account, it counts as the minor’s asset on the FAFSA form, not the asset of the custodian, who is often the parent” (FSA Handbook 2026–27, fsapartners.ed.gov, checked September 2026). Formula A of the 2026–27 SAI guide multiplies the student’s net worth by an asset conversion rate of 20%, with no allowance subtracted first (2026–27 SAI and Pell Grant Eligibility Guide, lines 31–36, fsapartners.ed.gov, checked September 2026). Every $1,000 adds $200 to the SAI.

Parent-owned 529: 12%, then the parent scale. For a dependent student, a 529 “is reported as a parental investment if the account is designated for the dependent student,” and “if the student is the beneficiary (but not the owner) of the account, the value is not reported as a student asset” (FSA Handbook 2026–27). The SAI guide adds parents’ net worth (which includes “qualified education benefits”), subtracts an asset protection allowance, multiplies by 12%, and adds the result to the parents’ adjusted available income (AAI). That total then runs through Table A5:

That is where the 5.64% everyone quotes comes from: 0.12 × 0.47 = 0.0564. It is the ceiling, not a flat rate. In the lowest band the same account costs 2.64%.

The asset protection allowance does not soften this. Table A4 of the 2026–27 guide sets it at $0 for every parent age, one parent or two. Older articles written for the EFC formula still describe it as a shelter.

Applied to whole balances, while the added amount stays inside one band:

The UTMA costs 3.55 times as much at the top band (20 ÷ 5.64) and 7.58 times as much at the bottom (20 ÷ 2.64).

A large balance can push parents across bands, so the exact figure comes from running Table A5 before and after. Three worked cases:

The last row crosses three bands: $1,800 at 22%, $5,500 at 25% and $4,700 at 29% is $396 + $1,375 + $1,363 = $3,134.

Four limits on these numbers:

• SAI is an index, not an aid award. It is an input schools use; the dollars a school offers are a separate decision.
• It is the federal formula only. Schools that use their own methodology can count these accounts differently.
• The 529 sits on top of everything else. Parents’ net worth includes cash and other investments, so the 529 is added to them, not assessed alone.
• Some families report no assets at all. The SAI guide notes that “certain applicants will be exempt from asset reporting based on income and federal benefits received.” For them, neither account moves the SAI.

What the money can be spent on

UTMA/UGMA: anything, as long as it is for the child’s benefit while you are custodian (fidelity.com). After the handover the child decides.

529: qualified expenses come out free of federal tax on the earnings. Section 529 and IRS Topic 313 (irs.gov, law.cornell.edu, both checked September 2026) list:

• College tuition, fees, books, supplies and required equipment.
• Room and board for a student enrolled at least half-time.
• Computers, software and internet access used primarily by the student while enrolled.
• K–12 tuition and related expenses, up to $20,000 a year ($10,000 before December 31, 2025).
• Fees, books, supplies and equipment for a registered apprenticeship program.
• Student-loan principal or interest for the beneficiary or a sibling, up to $10,000 lifetime per individual.

What happens if the plan changes

A UTMA has no “plan” to change: the money is the child’s whatever they end up doing. A 529 has four exits.

Change the beneficiary. Switching to a member of the old beneficiary’s family is not treated as a distribution. Moving money to another 529 for a family member is also tax-free if it is done within 60 days (§529(c)(3)(C)).

Roll to a Roth IRA. IRS Topic 313 sets the conditions: a direct trustee-to-trustee transfer, subject to the Roth IRA annual limit and a $35,000 lifetime limit, from a 529 open at least 15 years, and not from contributions (or their earnings) made in the last five years (irs.gov, checked September 2026). The statute requires the Roth IRA to be “maintained for the benefit of such designated beneficiary” — the child’s Roth, not yours (§529(c)(3)(E)). The 2026 IRA limit is $7,500 (irs.gov, checked September 2026), so reaching $35,000 takes at least five years of rollovers at that limit: 35,000 ÷ 7,500 = 4.67.

Use a penalty exception. The 10% additional tax does not apply to distributions after the beneficiary’s death, on account of disability, or up to the amount of a tax-free scholarship (26 U.S.C. §530(d)(4)(B), applied to 529s by §529(c)(6), law.cornell.edu, checked September 2026).

Take a non-qualified withdrawal. The earnings portion is subject to federal income tax and “an additional 10% federal tax penalty on earnings,” and possibly state tax (investor.gov, checked September 2026). The statute sets it at “10 percent of the amount which is so includible” (§530(d)(4)(A)).

How much can go in

There is no federal dollar cap on 529 contributions. The statute requires each program to have “adequate safeguards to prevent contributions on behalf of a designated beneficiary in excess of those necessary to provide for the qualified higher education expenses” (§529(b)(6)), so each program sets its own maximum.

Contributions are gifts. The 2026 annual gift-tax exclusion is $19,000 (irs.gov, checked September 2026). Section 529(c)(2)(B) lets a donor whose 529 contributions exceed that in a year elect to spread them “ratably over the 5-year period,” so one donor can put 5 × $19,000 = $95,000 into a 529 for one beneficiary in a single year and have it treated as five years of annual exclusions.

Taxes

529 earnings withdrawn for qualified expenses are not subject to federal income tax (investor.gov, checked September 2026). Income in a UTMA/UGMA is taxed to the child under the kiddie-tax rules; the custodial account tax calculator works through the thresholds and the bill.

To project what either account might grow to, the investing for kids calculator runs the numbers.
