You want to save for college. Two tools come up a lot: the 529 plan and the Roth IRA. Both have tax benefits. But they work very differently. Here is how to choose the right one — or how to use both.
What Is a 529 Plan?
A 529 is a savings plan designed for education. You put money in after taxes. The money grows tax-free. And you pay no taxes when you take it out for education expenses.
Each state offers its own 529. You do not have to use your home state’s plan. You can pick any state’s plan.
Qualified expenses include tuition, room and board, books, computers, and K-12 private school tuition (up to $10,000/year). Starting in 2024, unused 529 funds can also be rolled into a Roth IRA for the beneficiary (with limits).
What Is a Roth IRA?
A Roth IRA is a retirement account. You put money in after taxes. It grows tax-free. You can take out contributions (not earnings) at any time without penalty. Earnings can also be used for college with no 10% penalty, though income taxes may apply.
In 2026, you can contribute up to $7,000 per year ($8,000 if you are 50 or older). There are income limits: single filers can contribute fully up to $146,000. It phases out above that.
Contribution limits and income thresholds as of May 2026.
529 vs Roth IRA: Side-by-Side
| Feature | 529 Plan | Roth IRA |
|---|---|---|
| Contribution limit | No annual limit (gift tax rules apply) | $7,000/year |
| Tax on growth | Tax-free (for qualified expenses) | Tax-free (for retirement; partial for college) |
| Penalty-free withdrawals | For qualified education expenses only | Contributions any time; earnings for education w/o penalty |
| Financial aid impact | Lower impact (parent asset) | Not counted as an asset if owned by parent |
| Flexibility | Must use for education (or roll to Roth) | Can use for retirement if not needed for college |
| State tax deduction | Often available (in-state plans) | None |
Financial Aid Impact
529 plans owned by a parent are counted as parent assets on the FAFSA. This reduces aid by at most 5.64% of the account value. That is relatively low.
A Roth IRA is a retirement account. It is not reported as an asset on the FAFSA at all. But withdrawals from a Roth IRA for college are reported as student income on the next year’s FAFSA. Income has a heavier impact than assets. This can hurt your financial aid.
The 529 Roth IRA Rollover Rule (2024+)
A newer rule lets you roll unused 529 funds into a Roth IRA for the same beneficiary. Rules:
- The 529 must be at least 15 years old
- Lifetime rollover limit: $35,000
- Annual limit equals that year’s Roth IRA contribution limit
This reduces the “what if we overfund it” risk of the 529. That was a major concern before this rule.
When to Use a 529
Use a 529 if:
- You are confident your child will attend college
- Your state offers a tax deduction for contributions
- You want to save more than the Roth IRA limit allows
- You want a dedicated college savings bucket
When to Use a Roth IRA for College
Use a Roth IRA if:
- You are not sure your child will go to college
- You want the money to double as retirement savings
- You are near the Roth income limit and want to start before you are phased out
Using Both Together
Many families use both. Max out your Roth IRA first (it builds retirement security). Then put extra college savings in a 529. This gives you flexibility. If your child gets a full scholarship, the Roth money stays as retirement savings.

Frequently Asked Questions
Can I use a Roth IRA to pay for college without penalty?
Yes. The 10% early withdrawal penalty is waived for qualified higher education expenses. However, income taxes may still apply on the earnings portion of the withdrawal.
Does a 529 plan affect FAFSA?
Yes, but the impact is small. A parent-owned 529 is counted as a parent asset. The maximum impact is 5.64% of the account value — much less than student assets.
What happens to a 529 if my child does not go to college?
You have several options: change the beneficiary to another family member, use it for K-12 private school, roll up to $35,000 into a Roth IRA for the beneficiary, or take a non-qualified withdrawal (taxes + 10% penalty on earnings apply).
How much should I put in a 529 each month?
A common rule of thumb: save about $250-$500/month starting at birth to cover a significant portion of four-year college costs. The earlier you start, the less you need to save each month thanks to compound growth.
Is a 529 or Roth IRA better if I am starting late?
If your child is close to college age, a 529 is usually better because you get the tax-free growth on education withdrawals immediately. The Roth IRA is better for flexibility if the timeline is uncertain or you need dual-purpose savings.
