Yes, a custodial account affects financial aid, and it hits harder than most other savings. Money in a UGMA or UTMA account legally belongs to the child, so the FAFSA treats it as a student asset and assesses it at 20% when calculating the Student Aid Index. Parent-owned assets are assessed at 12%. The same dollar amount reduces need-based aid by nearly twice as much when it sits in a custodial account instead of a parent’s brokerage.
Why the Account Counts as the Student’s
When an adult funds a UGMA or UTMA account, the money belongs to the child the moment it lands. The custodian manages it until the child reaches adulthood, but ownership never sat with the custodian. Federal need analysis under 20 U.S. Code § 1087oo adds the student’s own assets to the Student Aid Index, and because the child holds legal title to every dollar, the full balance counts.1Office of the Law Revision Counsel. 20 USC 1087oo – Student Aid Index for Dependent Students There’s no carve-out for the child’s age or for the fact that a parent still controls the investments.
How Much Aid the 20% Rate Actually Costs
The SAI formula multiplies a dependent student’s assets by 20% and adds the result to the index. Parent assets get a flat 12%.2Federal Student Aid. Student Aid Index (SAI) and Pell Grant Eligibility – 2024-2025
Run the numbers on a $30,000 balance. In a UGMA, it adds $6,000 to the SAI. In a parent’s account, it adds $3,600. That $2,400 gap means $2,400 less need-based aid every year the account is reported. Over four years, the classification alone can cost close to $10,000 in aid.
Parents sometimes assume their own assets are shielded by a protection allowance. For the 2026–27 award year, that allowance for parents is zero. Every reportable dollar feeds the 12% calculation. Student assets have never had a protection allowance at all; the formula assumes the student can spend one-fifth of their savings on tuition each year.
Reporting a Custodial Account on the FAFSA
The FAFSA asks for the student’s current net worth of investments as of the date you sign. The full value of every UGMA or UTMA account belongs on that line, including stocks, bonds, mutual funds, and cash sitting in the account. Pull a current statement so the number is accurate to the day.
If the custodial account holds non-liquid assets like real estate, report the current market value minus any debt tied to that property. A quick estimate from a county assessor’s site works for the value; subtract any outstanding mortgage or lien to get net worth.
One point trips families up: if a parent is the custodian of a UGMA or UTMA for a sibling who is not the FAFSA applicant, that account is not reported on this student’s FAFSA. Only custodial accounts where the applicant is the beneficiary go on the form. Accuracy matters. Deliberately misreporting assets is a federal crime carrying fines up to $20,000 or up to five years in prison.3Office of the Law Revision Counsel. 20 USC 1097 – Criminal Penalties
Shifting the Account to a Custodial 529
The biggest planning lever is the 529 plan. Federal law treats a 529 as a parent asset when the student is a dependent, even if the student is the account owner or beneficiary.4Office of the Law Revision Counsel. 20 USC Chapter 28, Subchapter IV, Part F – Need Analysis Moving money from a UGMA or UTMA into a custodial 529 drops the assessment rate from 20% to 12%. On a $30,000 balance, the annual aid impact falls from $6,000 to $3,600.
There are two catches. First, 529 plans only accept cash contributions, so the investments inside the custodial account have to be sold. Those sales trigger capital gains taxes, and because the child owns the account, the gains land on the child’s tax return. For 2025 and 2026, a child’s unearned income above $2,700 is subject to the kiddie tax, which applies the parents’ marginal rate rather than the child’s lower rate.5Internal Revenue Service. Topic No. 553, Tax on a Child’s Investment and Other Unearned Income (Kiddie Tax) The kiddie tax reaches children under 18, children who are 18 and don’t earn more than half their own support, and full-time students ages 19 through 23 in the same position. Spreading sales over several years keeps each year’s unearned income closer to the threshold.
Second, you can’t just move the money into a parent-owned 529 with no custodial designation. The assets belong to the child, and that obligation follows the money. A custodial 529 keeps the child as owner while picking up the favorable FAFSA treatment. More than two-thirds of states also offer an income tax deduction or credit for 529 contributions, which custodial accounts don’t provide.
Why Withdrawal Timing Matters
The FAFSA pulls income from two years before the academic year. For a student entering college in fall 2027, the FAFSA uses 2025 income. For sophomore year, it uses 2026. Any taxable event inside a custodial account echoes forward into a financial aid calculation two years later.
A large sale during freshman year shows up as income on the FAFSA for junior year. Big capital gains inflate the student’s adjusted gross income and can push the SAI higher in a year the family wasn’t expecting it. The safest window to convert a custodial account to a 529 is before January 1 of the student’s sophomore year of high school, which puts the gain far enough back that it won’t hit any FAFSA filing. If you plan to spend the account down on tuition instead of converting, time the withdrawals for years that won’t feed into a FAFSA.
Asking the School for a Professional Judgment Adjustment
Financial aid officers can adjust SAI components on a case-by-case basis through professional judgment. Federal law lists a change in assets as one example that can justify an adjustment.6Federal Student Aid. Special Cases – 2025-2026 Federal Student Aid Handbook If the custodial balance has dropped sharply since the FAFSA was filed, or if funds were spent on documented medical or other needs, you can ask the school to reconsider.
This isn’t an online appeal form. You contact the financial aid office directly, explain the circumstance in writing, and provide documentation. The school makes the call, and any adjustment applies only at that institution. There’s no guarantee, but it’s worth asking when a custodial balance paints a misleading picture of what the family can actually pay.
When a Custodial Account May Not Move the Number
For families with income near or below the federal poverty guidelines, the SAI formula can produce an automatic zero, which maximizes Pell Grant eligibility no matter how much the student has in assets. Dependent students qualify when parents’ adjusted gross income sits at or below 175% of the poverty guideline for the family size, or 225% for single-parent households.7Federal Student Aid. 2026-27 Student Aid Index (SAI) and Pell Grant Eligibility Guide When that pathway applies, the custodial balance effectively drops out of the federal calculation.
Families landing just above these thresholds get no partial break. The 20% assessment hits in full even on a modest balance. A $5,000 UGMA still adds $1,000 to the SAI.
The Deadline Age of Majority Puts on Planning
Custodial accounts have a built-in expiration date. Under UGMA rules, the child gains full control of the account at 18. UTMA accounts typically transfer at 21, though some states allow the account creator to set the transfer age at 18. Once the child reaches the applicable age, the custodian is out of the picture, and the child can spend the money on anything, with no obligation to use it for school.
A student who gains control of a $40,000 account at 18 might spend part of it before the next FAFSA filing. A lower balance produces a lower SAI, but the spending itself generates no aid benefit unless it goes toward allowable educational costs. And if the money goes to a car instead of tuition, the family has lost both the savings and the aid reduction it hoped to achieve. Any conversation about spending expectations needs to happen well before the child reaches the age of majority, not after.
