Complete 529 college savings plan guide for 2026. Learn about state tax deductions, contribution limits, superfunding strategies, qualified expenses, and the new 529-to-Roth IRA rollover option.
What Is a 529 Plan?
A 529 plan is a tax-advantaged savings account designed for education expenses. Named after Section 529 of the Internal Revenue Code, these plans offer federal tax-free growth and often state tax deductions for contributions.
Two Types of 529 Plans
| Plan Type | Description | Availability |
|---|---|---|
| 529 Savings Plan | Investment account that grows tax-free | All states offer these |
| Prepaid Tuition Plan | Lock in today's tuition rates | Limited states, usually state schools only |
This guide focuses on 529 Savings Plans, which are more flexible and widely used.
Key Benefits
- Tax-free growth: No federal taxes on investment gains
- Tax-free withdrawals: For qualified education expenses
- State tax deductions: Many states offer deductions for contributions
- High contribution limits: Often $300,000+ lifetime per beneficiary
- Flexibility: Can change beneficiaries within family
- No income limits: Anyone can contribute regardless of income
How 529 Plans Work
| Step | What Happens | Tax Impact |
|---|---|---|
| 1. Open account | Choose state plan, name beneficiary | None |
| 2. Contribute | Deposit after-tax dollars | State deduction possible |
| 3. Invest | Choose from plan's investment options | No annual taxes on gains |
| 4. Withdraw | Use for qualified education expenses | Completely tax-free |
Contribution Rules & Limits
Annual Gift Tax Exclusion
529 contributions are considered gifts. In 2026, you can contribute up to $18,000 per beneficiary without gift tax implications ($36,000 for married couples giving jointly).
| Contributor | 2026 Annual Limit (per beneficiary) |
|---|---|
| Individual | $18,000 |
| Married couple | $36,000 |
| Grandparent | $18,000 (or $36,000 with spouse) |
Multiple people can contribute to the same beneficiary's 529. Grandparents, aunts, uncles, and friends can all add funds.
Lifetime Limits by State
Each state sets maximum lifetime contribution limits per beneficiary:
| State | Lifetime Limit |
|---|---|
| California | $529,000 |
| New York | $520,000 |
| Texas | $500,000 |
| Pennsylvania | $511,758 |
| Virginia | $550,000 |
These limits are per beneficiary, not per account. If grandparents and parents both have accounts for the same child, combined contributions count toward the limit.
No Annual Contribution Limit
Unlike IRAs, there's no annual IRS limit on 529 contributions (just the gift tax threshold). You could contribute $100,000 in one year if you wanted—you'd just need to file a gift tax return and potentially use lifetime exemption.
State Tax Deductions
One of the biggest 529 benefits is the state tax deduction for contributions. This varies significantly by state.
States with Unlimited Deductions
These states let you deduct your entire contribution (for residents using their state's plan):
- Colorado
- New Mexico
- South Carolina
- West Virginia
States with Generous Deductions
| State | Annual Deduction Limit | Tax Savings Example* |
|---|---|---|
| Pennsylvania | $18,000 per beneficiary | $549 (3.07%) |
| New York | $5,000 ($10,000 married) | $850 (8.5%) |
| Virginia | $4,000 (unlimited if 70+) | $230 (5.75%) |
| Illinois | $10,000 ($20,000 married) | $495 (4.95%) |
| Ohio | $4,000 per beneficiary | $150 (3.75%) |
*Based on maximum deduction at top state rate.
States with No Income Tax
These states have no income tax, so no 529 deduction applies:
- Alaska
- Florida
- Nevada
- South Dakota
- Texas
- Washington
- Wyoming
Residents of these states can use any state's 529 plan with no state tax implications.
Choosing a State Plan
| Your State Offers | Recommendation |
|---|---|
| Strong deduction + good investments | Use your state's plan |
| Strong deduction + poor investments | Split: some in-state, some elsewhere |
| No deduction or no income tax | Choose best plan nationally |
| Weak deduction + high fees | Consider out-of-state plan |
Top-rated 529 plans nationally include Utah's my529, Nevada's Vanguard 529, and New York's Direct Plan.
Investment Options
529 plans offer investment menus similar to 401(k)s, but typically more limited.
Common Investment Types
| Option | Description | Best For |
|---|---|---|
| Age-based portfolios | Automatically adjusts allocation as child ages | Hands-off investors |
| Static portfolios | Fixed allocation (e.g., 80/20 stocks/bonds) | Those who want control |
| Individual funds | Build your own portfolio | Experienced investors |
| Money market/Stable value | Capital preservation | Near-term expenses |
Age-Based Portfolio Glide Path
Example of how age-based portfolios typically shift:
| Child's Age | Stocks | Bonds | Cash |
|---|---|---|---|
| 0-5 | 80% | 15% | 5% |
| 6-10 | 70% | 25% | 5% |
| 11-14 | 50% | 40% | 10% |
| 15-17 | 25% | 50% | 25% |
| 18+ | 10% | 40% | 50% |
Expense Ratios Matter
Compare total costs between plans:
- Low-cost plans: 0.10% - 0.25% annual fees
- Average plans: 0.25% - 0.50% annual fees
- High-cost plans: 0.50% - 1.00%+ annual fees
Over 18 years, the difference between 0.15% and 0.75% fees on a $100,000 account is approximately $15,000 in lost growth.
Qualified Expenses
529 funds can be used tax-free for a wide range of education expenses.
College and Graduate School
- Tuition and fees: Any accredited institution
- Room and board: Up to school's cost of attendance
- Books and supplies: Required materials
- Computers and equipment: For student's use
- Internet service: While enrolled
- Special needs expenses: Related to enrollment
K-12 Education (Limited)
Up to $10,000 per year per beneficiary for K-12 tuition at public, private, or religious schools. Does not include room, board, or supplies for K-12.
Apprenticeship Programs
Registered apprenticeship programs qualify for:
- Fees and tuition
- Books and supplies
- Required equipment
Student Loan Repayment
Up to $10,000 lifetime per beneficiary can pay student loans. This is a lifetime limit, not annual.
What's NOT Qualified
- Transportation costs
- Health insurance
- Student activity fees (unless required for enrollment)
- Sports or club fees
- Cell phone bills
Non-Qualified Withdrawal Penalties
If you withdraw for non-qualified expenses:
- Earnings portion is taxed as ordinary income
- 10% penalty on earnings
- Original contributions are NOT taxed or penalized
Superfunding Strategy
Superfunding allows you to contribute up to 5 years' worth of gifts in a single year—a powerful strategy for jump-starting education savings.
How Superfunding Works
| Year | Normal Gift Limit | Superfunding Limit |
|---|---|---|
| 2026 | $18,000 individual | $90,000 individual |
| 2026 | $36,000 married | $180,000 married |
Rules and Requirements
- You must elect to treat the gift as made over 5 years on your tax return (Form 709)
- No additional gifts to that beneficiary for the next 4 years
- If you die during the 5-year period, a portion may be included in your estate
Why Superfunding Is Powerful
Getting money in early maximizes tax-free growth time:
| Strategy | Total Contributed | Value at 18 years (7%) |
|---|---|---|
| Superfund $90,000 at birth | $90,000 | $304,000 |
| $5,000/year for 18 years | $90,000 | $181,000 |
Same total contribution, but superfunding produces $123,000 more due to earlier investment.
Grandparent Superfunding
Grandparents can superfund for multiple grandchildren:
- Married couple with 4 grandchildren: $180,000 x 4 = $720,000
- Reduces estate while providing education funds
- Removes future growth from estate
New 529-to-Roth Rollover
Starting in 2024, a new provision allows unused 529 funds to be rolled over to a Roth IRA. This is a game-changer for 529 planning.
The Basic Rules
| Requirement | Details |
|---|---|
| Lifetime limit | $35,000 per beneficiary |
| Annual limit | Subject to Roth IRA contribution limits ($7,000 in 2026) |
| Account age requirement | 529 must be open for 15+ years |
| Contribution timing | Contributions/earnings from last 5 years ineligible |
| Beneficiary | Rollover goes to 529 beneficiary's Roth IRA |
Why This Matters
Before this rule, leftover 529 funds created a dilemma:
- Pay taxes and penalties on non-qualified withdrawals
- Change beneficiary and hope someone else uses it
- Keep it for graduate school that may never happen
Now, excess funds can become tax-free retirement savings for your child.
Strategic Planning
For a newborn, open a 529 immediately to start the 15-year clock:
| Age | Action |
|---|---|
| 0 | Open 529, start contributions |
| 15 | 529 becomes eligible for Roth rollover |
| 18-22 | Use 529 for college |
| 22+ | Roll unused funds to child's Roth IRA |
Example Rollover Timeline
Child has $50,000 left in 529 after college:
| Year | Rollover Amount | Cumulative Transferred | Remaining in 529 |
|---|---|---|---|
| 1 | $7,000 | $7,000 | $43,000 |
| 2 | $7,000 | $14,000 | $36,000 |
| 3 | $7,000 | $21,000 | $29,000 |
| 4 | $7,000 | $28,000 | $22,000 |
| 5 | $7,000 | $35,000 | $15,000 |
After 5 years, $35,000 has been moved to the child's Roth IRA (lifetime limit reached). The remaining $15,000 stays in the 529 for future education or changes beneficiary.
Your Action Plan
If Your Child Is a Newborn
- Open a 529 immediately (starts 15-year Roth rollover clock)
- Check your state's tax deduction benefits
- Set up automatic monthly contributions
- Choose age-based portfolio option
- Share account info with grandparents for gifts
If Your Child Is School-Age
- Calculate estimated college costs
- Determine how much you can save monthly
- Consider superfunding if you have the resources
- Choose appropriate investment aggressiveness based on timeline
If College Is Approaching (3-5 Years)
- Shift to more conservative investments
- Calculate expected qualified expenses
- Understand withdrawal process
- Keep receipts for all qualified expenses
Contribution Strategy by Timeline
| Years to College | Investment Approach | Action Focus |
|---|---|---|
| 15+ | Aggressive (80%+ stocks) | Maximize contributions, superfund if possible |
| 10-15 | Moderately aggressive | Steady contributions, take state deduction |
| 5-10 | Moderate | Balance growth with preservation |
| 0-5 | Conservative | Protect principal, calculate needs |
Key Numbers to Remember
| Item | 2026 Amount |
|---|---|
| Annual gift tax exclusion | $18,000 per beneficiary |
| Superfunding maximum (5 years) | $90,000 individual / $180,000 married |

| Roth rollover lifetime limit | $35,000 |
