Hawaii 529 Plans At A Glance

Hawaii 529 Tax Rules

Hawaii doesn't offer an income tax deduction or credit for contributions to HI529 or any other 529 plan (HI529). A 2025 bill that would have created a $5,000 deduction ($10,000 joint) was carried over to the 2026 session and died without passing (BillTrack50). Our state-by-state 529 tax deduction table shows what neighboring plans offer their own residents.

Hawaii adopts the federal 529 rules with three exceptions, and Act 35 of 2026 kept those exceptions in place for tax years starting in 2026 (Hawaii Revised Statutes § 235-2.4; Hawaii Legislature). Growth is tax-deferred and qualified college withdrawals are tax-free, including at out-of-state schools, which our list of qualified 529 plan expenses breaks down.

Churning doesn't apply in Hawaii the way it does in states with a deduction. Families in states like Alabama can route tuition through a 529 for a quick deduction, but Hawaii offers no deduction to claim, and neither Hawaii's tax law nor the HI529 disclosure statement sets a holding period (Hawaii Revised Statutes § 235-2.4; HI529 Plan Disclosure Statement). Our breakdown of 529 plan churning and withdrawal limits explains which states restrict the move.

Roth rollovers work in Hawaii's favor. Federal law lets a 529 that's been open at least 15 years roll up to $35,000 into the beneficiary's Roth IRA, and under current Hawaii law the earnings portion of that rollover isn't subject to Hawaii income tax (HI529 Plan Disclosure Statement, January 2024 supplement). Read our 529-to-Roth IRA rollover rules before you move leftover money.

The K-12 and computer rules are where Hawaii breaks from federal law. Hawaii switches off the federal provisions that treat K-12 expenses and computers, software, and internet access as qualified, so the earnings on those withdrawals count as Hawaii income (Hawaii Revised Statutes § 235-2.4), and the plan's October 2025 supplement confirms the K-12 treatment. Hawaii hasn't published separate guidance on the new federal credential-program expenses, so check with the Department of Taxation first, and see our breakdown of the 2026 529 plan expansion for what changed federally.

How Hawaii's 529 Plan Ranks

Hawaii ties Alaska for last place, 49th of the 50 state plans in our best 529 plans rankings, which include Washington, D.C., with a 51.4% net return on investment. Our Net ROI score models $100 a month for 10 years at a 5% annual return, subtracts plan fees, and reinvests the value of the state tax break each year. HI529 lands at the bottom because its 0.55% fee is high for a plan with no tax break, and Hawaii offers no deduction to offset it.

Hawaii has no bordering states, so the table compares it with the West Coast plans and Alaska, which also give no state tax break. Because HI529 carries no Hawaii tax edge, a Hawaii resident gives up nothing on the state return by using another state's plan, so compare fees directly, and the full rankings table lists all 50 state plans with their fees.

The gap with the top of the list comes down to two levers Hawaii controls. Indiana's 20% tax credit is what puts it at #1, while Hawaii offers no tax break and charges more than any other plan in the table, so a deduction or lower fees would move Hawaii families up. If that matters to you, share these numbers with your state legislators, and use our 529 plan tax deductions by state table to show how other states reward savers.

Should Hawaii Residents Use HI529?

Only if you value a Hawaii-sponsored account enough to pay more for it. HI529 waives its $20 account fee for Hawaii residents, but that's the only perk tied to residency, since Hawaii gives no deduction and treats qualified withdrawals from any state's plan the same way (HI529). Several plans in our best 529 plans rankings charge less than 0.10% a year, and on a $20,000 balance each 0.10% of fees costs about $20 a year.

Families who already hold HI529 can roll it to another state's plan without Hawaii recapture, and our explainer on 529 plan rollovers and transfers covers the once-per-year federal limit. Hawaii state employees can also contribute to HI529 through payroll deduction (Hawaii Department of Human Resources Development), which some families will find worth the higher cost, and our look at where to open a 529 plan weighs convenience against fees.

Four years at an in-state Hawaii public university runs close to $118,000 on campus, so the average HI529 balance of about $20,400 covers less than one year. Our Hawaii college costs and financial aid breakdown lists costs by school, and our 529 savings benchmarks by age show what to aim for.

Hawaii 529 Plan Details

HI529 is overseen by the State of Hawaii through the Director of Finance, with Ascensus as program manager and Vanguard managing the investment options (Hawaii Department of Budget and Finance). As of June 30, 2026, HI529 held $143.2 million across 7,012 open accounts, the smallest total of the 50 states and D.C. in 529 assets (The 529 Network). Our 529 plan and college savings statistics show how that compares nationally.

Other Hawaii College Savings Programs

Upromise. Upromise lets you earn money for your HI529 account through rebates and rewards on everyday spending, and the Upromise credit card sends cash back straight into your child's 529 plan (Upromise). You can link an HI529 account to your Upromise profile, which matters more in Hawaii because the state offers no tax deduction to add to your savings.

Hawaii ABLE Savings Program. Hawaii residents with disabilities can save in the Hawaii ABLE Savings Program, a 529A account that's part of Oregon's ABLE for ALL network (Hawaii Department of Budget and Finance). ABLE distributions are tax-free when used for qualified disability expenses, and our 529 plan overview compares ABLE accounts with regular college savings.

Leftover money. Families with money left after college can change the beneficiary to a sibling, pay down up to $10,000 of student loans, or roll to a Roth IRA without Hawaii tax on the earnings. Our list of what to do with leftover 529 money covers each option, and Hawaii graduates in teaching or health care should also check Hawaii student loan repayment assistance programs.
