Quick Answer
529 plans offer high, unlimited-income contribution limits, no federal deduction, tax-deferred growth, and tax-free qualified withdrawals, with the account owner keeping control. Coverdell ESAs cap contributions at $2,000 per beneficiary, add income limits, but allow broader investments and uncapped K-12 use. SECURE 2.0 lets excess 529 funds roll into the beneficiary's Roth IRA.
Education is one of the largest expenses families plan for, and two primary tax-advantaged account types exist to help: 529 plans and Coverdell ESAs. Understanding their differences is frequently tested on the Series 66.
529 Plans (Qualified Tuition Programs)
529 plans are state-sponsored, tax-advantaged savings plans designed for education expenses. Nearly every state offers at least one plan (a few states, such as Wyoming, do not), and education savings plans can generally be opened in any state regardless of where you live, though some plans and most prepaid tuition plans have residency requirements.
There are two types of 529 plans:
Prepaid Tuition Plans
- Lock in current tuition rates at eligible institutions
- Generally cover tuition and mandatory fees (not room and board); a few state plans offer add-on coverage beyond that standard
- State-guaranteed in many cases
- Limited to in-state public colleges in most plans
Education Savings Plans
- Investment accounts with tax-deferred growth and tax-free withdrawals for qualified expenses
- More flexible than prepaid plans; can be used at any eligible institution nationwide
- Investment options typically include mutual funds and age-based portfolios
- Account value fluctuates with market performance (no guaranteed returns)
Key 529 Plan Rules
- Tax treatment: Contributions are not federally tax-deductible, but many states offer state tax deductions or credits. Earnings grow tax-deferred, and qualified withdrawals are tax-free
- Qualified expenses: Tuition, fees, books, supplies, room and board (student must be enrolled at least half-time; capped at the school's cost-of-attendance figure, or the actual amount charged for housing owned or operated by the school if higher), computers, and up to $20,000/year for K-12 expenses (not just tuition, also curriculum, tutoring, testing, and other qualified K-12 costs)
- Non-qualified withdrawals: Earnings are subject to ordinary income tax plus a 10% penalty, though the penalty (not the income tax) has exceptions for death, disability, scholarships, military academy attendance, and amounts coordinated with education tax credits
- Contribution limits: No annual federal limit, but high aggregate limits set by each state (typically $300,000+). Contributions are considered completed gifts for gift tax purposes
- Account ownership: The account owner retains control (not the beneficiary); this is a key advantage over custodial accounts
- Beneficiary changes: Can be changed to another qualifying family member without penalty
- No income limits: Anyone can contribute (parents, grandparents, friends) regardless of income
- No age limits: Unlike Coverdell ESAs, there is no age restriction on the beneficiary
Exam Tip: Gotchas
- 529 contributions are not federally tax-deductible. Many states offer state deductions, but there is no federal deduction. Students often confuse this with IRA deductibility.
- 529 plans have no income limits for contributors. Anyone can contribute regardless of income (unlike Coverdell ESAs).
SECURE 2.0: 529-to-Roth IRA Rollovers
Starting January 1, 2024, excess 529 funds can be rolled into a Roth IRA for the beneficiary, not the account owner. This is a statutory carve-out: the account owner's general control over the 529 (described above) does not extend to choosing the rollover destination.
The law fixes the rollover destination to a Roth IRA owned by the beneficiary. This gives families a way to repurpose leftover education funds for retirement savings.
Think of it this way: If a child gets a scholarship or chooses a less expensive school, the 529 could end up with more money than needed. A withdrawal up to the scholarship amount is already exempt from the 10% penalty (though the earnings are still taxable), but the family can also move leftover funds into a Roth IRA for the child's retirement instead, even though the owner is the one who directs everything else about the account.
Requirements:
- 529 account must have been open for at least 15 years
- $35,000 lifetime rollover limit (across all 529 accounts for that beneficiary)
- Contributions (and their earnings) made within the last 5 years cannot be rolled over
- Subject to annual Roth IRA contribution limits; beneficiary must have earned income at least equal to the amount rolled over
- Roth IRA income limits do not apply to 529 rollovers
- Must be a direct trustee-to-trustee transfer
Exam Tip: Gotchas
- Whether changing the 529 beneficiary resets the 15-year clock is not yet settled. Practitioner groups (including the IRS Advisory Council) have asked the IRS to address this question, but the IRS has not issued final guidance. Do not treat "the clock resets on a beneficiary change" as established law.
- The rollover goes to the beneficiary's Roth IRA, not the account owner's, even though the owner otherwise controls the 529. Owning and directing the account is not the same as owning the rollover destination.
- "Contribution limit" and "income limits" are two different rules, and only one applies to these rollovers. The rollover uses up the beneficiary's remaining annual Roth IRA contribution room ($7,500 for 2026, reduced by any Roth or traditional IRA contributions the beneficiary already made that year); it is not a separate $7,500 allowance on top of normal IRA contributions. The MAGI phase-out that normally blocks high earners from contributing to a Roth IRA directly does not apply here.
Coverdell Education Savings Accounts (ESAs)
Coverdell ESAs are tax-advantaged accounts for education expenses that offer broader investment flexibility than 529 plans but come with much lower contribution limits ($2,000 per year vs. no federal limit for 529s).
Key Coverdell ESA Rules
- Qualified expenses: Both K-12 and higher education expenses (529 plans only allow $20,000/year for K-12)
- Annual contribution limit: $2,000 per beneficiary, aggregate across all Coverdell accounts for that beneficiary, not per contributor (much lower than 529 plans)
- Income limits for individual contributors: Phaseout begins at $95,000 modified adjusted gross income (MAGI) for single filers ($190,000 for joint filers); fully phased out at $110,000/$220,000 (this income limit applies to individuals; organizations, such as corporations or trusts, can contribute without a MAGI test)
- Tax treatment: Same as 529: tax-deferred growth and tax-free qualified withdrawals
- Age restriction: Contributions must stop once the beneficiary turns 18 (waived for special-needs beneficiaries), and remaining funds are deemed distributed within 30 days after the beneficiary's 30th birthday unless rolled over or the beneficiary is changed to a family member under 30 (both age limits are waived for special-needs beneficiaries)
- Investment flexibility: Can invest in individual stocks, bonds, ETFs, mutual funds; much broader than most 529 plans
Account Control (Responsible Individual)
A Coverdell ESA is managed by a responsible individual, the person named on the account who authorizes investments, transfers, and distributions. This is usually the beneficiary's parent or legal guardian, and doesn't have to be whoever contributed the money.
Control here is not permanent by default: when the beneficiary reaches the age of majority under state law, the beneficiary automatically becomes the responsible individual, unless the ESA agreement elects to let the original responsible individual continue. Contrast this with a 529 plan, where the account owner keeps control indefinitely and the beneficiary never gains any rights to the account.
Exam Tip: Gotchas
- The $2,000 Coverdell limit is per beneficiary, not per contributor. A parent and a grandparent contributing to separate Coverdell accounts for the same child share a single $2,000 cap.
- Coverdell ESAs have income limits; 529 plans do not. Individual contributors must have modified adjusted gross income (MAGI) below $110,000 (single) or $220,000 (joint) to contribute to a Coverdell; organizations are not subject to this test.
- Coverdell covers K-12 expenses with no dollar cap. By contrast, 529 plans cap K-12 expenses (not just tuition) at $20,000 per year.
- Coverdell funds must generally be distributed within 30 days after the beneficiary turns 30. Any unused funds can instead be transferred to another qualifying family member under 30.
- Contributions to a Coverdell must stop once the beneficiary turns 18. This is a separate rule from the age-30 use deadline; special-needs beneficiaries are exempt from both age limits.
529 Plan vs. Coverdell ESA Comparison
| Feature | 529 Plan | Coverdell ESA |
|---|---|---|
| Annual contribution limit | No federal limit (state aggregate limits $300K+) | $2,000 per beneficiary |
| Income limits | None | $110,000 single / $220,000 joint |
| K-12 expenses | Up to $20,000/year | Fully covered (no dollar cap) |
| Higher education | Yes | Yes |
| Investment options | Plan-specific (typically limited) | Self-directed (stocks, bonds, ETFs) |
| Age limit on contributions | None | Must stop by age 18 |
| Age limit on use | None | Deemed distributed within 30 days of turning 30 (special-needs exception) |
| State tax deduction | Many states offer one | No |
| Roth IRA rollover | Yes (SECURE 2.0) | No |
| Account control | Owner retains control indefinitely | Responsible individual (parent/guardian) manages until beneficiary reaches age of majority, by default |
Exam Tip: Gotchas
- 529 account owners retain control of the account indefinitely. With a Coverdell, the responsible individual's control ends when the beneficiary reaches the age of majority under state law, at which point the beneficiary takes over by default. This ownership distinction matters when comparing to custodial accounts (UGMA/UTMA), where the minor gains control at the age of majority.
- The 529-to-Roth IRA rollover has strict requirements. The account must be open at least 15 years, contributions and earnings from the last 5 years are excluded, and there is a $35,000 lifetime rollover cap. Rollovers are also subject to annual Roth IRA contribution limits.
Think of it this way: Choosing between a 529 and a Coverdell comes down to three questions: How much do you want to contribute? (529 wins on limits.) Do you need K-12 flexibility without a cap? (Coverdell wins.) Do you want broader investment choices? (Coverdell wins.) For most families, 529 plans are the default because of the higher contribution limits and no income restrictions.
What Should You Check on Exam Day?
- 529 contributions are not federally tax-deductible; earnings grow tax-deferred, qualified withdrawals are tax-free; no income or age limits, and the account owner retains control
- Coverdell ESAs cap contributions at $2,000 per beneficiary, add income limits, but allow broader investments and no dollar cap on K-12 use
- Non-qualified 529 withdrawals: earnings generally taxed as ordinary income plus a 10% penalty, though the penalty has exceptions (death, disability, scholarship, military academy attendance, coordination with education credits)
- SECURE 2.0 lets excess 529 funds roll into the beneficiary's (not owner's) Roth IRA after the account has been open 15+ years, excluding the last 5 years' contributions and earnings, capped at $35,000 lifetime, subject to annual Roth IRA contribution limits (but not the MAGI phase-out)
