Best state 529 plan: is your state's tax deduction worth it?

Nobody tells you this when you open one, so here it is.

A 529 is state-sponsored, but the state on the account and the state on your driver's license do not have to match. Which leaves 2 questions, in order: does your state pay you to stay home, and what is the plan charging you a year?

Can I use another state's 529 plan?

Generally, yes. New York's plan, for 1, says it plainly in its FAQ: "you don't have to be a resident of New York."

The money is not stuck in that state either. Any school with a federal school code from the U.S. Department of Education counts as an eligible institution under Section 529, and that includes schools abroad that qualify.

So a dad in Ohio can hold a New York plan for a kid who ends up in Oregon. The only question the address on your tax return answers is whether your state hands you a deduction, and whether it cares which plan you picked to get it.

Does my state give a 529 tax deduction?

Start with the federal side, because it is the same for everybody. The IRS says in Publication 970: "You can't deduct either payments or contributions to a QTP." A QTP is the IRS name for a 529.

The deduction, where it exists, is a state thing. More than 30 states offer one, and most of them only give it for contributions to their own plan.

4 states with a broad income tax give nothing at all: California, Hawaii, Kentucky and North Carolina. If you file in 1 of those 4, the fee is the only number left to decide on.

An earlier version of this article also put Delaware, Maine and New Jersey on that no-deduction list. That was wrong. All 3 have a deduction, and here is what each one does.

The table covers the states people ask us about most. Rules for the other states change often enough that the state revenue department's own page is the only one to trust on the day you file.

Which states give a 529 deduction for any state's plan?

These are the tax parity states. Their break follows the contribution, not the plan, so a family there can pick on fees alone and still keep the deduction.

We left the dollar caps blank for the 7 states we could not read on a state page today. A made-up cap in a table looks exactly like a real one, and that is the whole problem with most 529 content.

What do 529 plan fees cost over 18 years?

Morningstar's 2026 study, using data as of Dec 31, 2025, gives 3 averages. Direct-sold plans, the kind you open yourself on the plan's website, average 0.30%. Advisor-sold plans average 0.79%.

Morningstar's own framing: "On average, a direct-sold plan comes at a 62% discount to an advisor-sold plan." Said the other way, 0.79% is about 163% more than 0.30%.

The third number is 0.43%. That is Morningstar's average for age-based and target-enrollment portfolios only, the ones that get more conservative as the kid gets older. It is not the average of every option inside every 529.

A few tenths of a percent sounds like nothing. Here is what it does to $150 a month.

You put in $32,400 in every row. The difference between the direct-sold average and the advisor-sold average is $3,167, and it is not a fee you paid once. It is a fee you paid 216 times and never saw a bill for.

Our original example still holds: 0.45% a year of extra drag on $150 a month over 18 years costs $3,031 of final balance. The villain here is not a bad plan. It is that the expensive version and the cheap version of the same thing look identical on the account-opening screen.

Is the state tax deduction worth more than the fee gap?

This is the fight that decides the whole article. On one side, a known tax break. On the other, a fee that compounds quietly for 18 years.

We ran it for a family putting in $1,800 a year ($150 a month) in a state with a flat 5% income tax. The deduction saves $90 a year, or $1,620 over 18 years. If each $90 refund goes back into the 529 once a year, it grows to about $2,994 by 18.

Read the top 2 rows again. The cheap out-of-state plan wins by $523 if the refund gets spent on diapers. The in-state plan wins by $851 if the refund goes back in. Same plans, same kid, and the winner flips on what happens to a $90 check every April.

The bottom 2 rows are less close. An in-state plan charging the advisor-sold average loses to a direct-sold average plan elsewhere either way, by $1,548 with the refund spent and $281 with it reinvested.

We also solved for the break-even. At a 5% state rate, the in-state plan can charge about 0.25 percentage points more than the other plan before the fee eats the deduction, or about 0.45 points if every refund is reinvested. At 9%, those numbers stretch to about 0.45 and 0.79 points.

Real deductions are capped and taxed at your marginal rate, not a flat one, so these are models. Change the rate or the cap and the break-even moves, which is why the method is spelled out below.

What is the best state 529 plan?

That is the most-searched version of this question, and no single plan wins it for every family. The math has a clear order of operations anyway.

First, the deduction. If your state gives one only for its own plan, that break is a known return, and the table above shows how big a fee gap it can cover. If you live in a parity state or 1 of the 4 no-deduction states, the deduction drops out of the decision.

Second, the all-in annual cost on the portfolio you will hold. For many families that is the age-based or target-enrollment option, which averages 0.43%, not a fund expense ratio shown on its own.

Third, whether you are looking at the direct-sold version. Many plans come in both flavors, and Morningstar's averages put a 0.49 percentage point gap between them.

Past returns show up in a lot of "best 529" lists too. Past returns are not promised again, and the fee is the only part of the result that is certain to be charged every year.

It does not have to be 1 plan forever, either. NY 529's FAQ says you can have multiple accounts in multiple states, for the same kid or different ones.

What is the best 529 plan for high earners?

The same 2 numbers decide it. The difference is that income limits can knock out the first one.

Delaware's deduction stops at federal AGI of $100,000 ($200,000 joint). Maine's needs income under $100,000 single or $200,000 joint. New Jersey's needs gross income of $200,000 or less.

In those 3 states, above those lines, the deduction drops out and the fee is the only number left to decide on. Not every state has an income limit, so check your own state's rule.

Where a deduction still applies, a higher state rate stretches it. At 9%, the in-state plan can charge about 0.45 points more before the fee eats the deduction, or about 0.79 points if every refund is reinvested.

There is no income ceiling on putting money in. IRS Publication 970 says "There are no income restrictions on the individual contributors."

Big lump sums bring in gift tax rules instead. NY 529's FAQ says contributions plus other gifts to 1 beneficiary up to $19,000 a year ($38,000 for married couples making a proper election) carry no gift tax. Up to $95,000 ($190,000 for couples) can go in at once by electing to spread it over 5 years. The IRS lists the same $19,000 annual exclusion for 2026.

When should I open a 529 plan?

The calendar moves the balance more than the plan does. Same $150 a month, same 7%, different start ages.

Waiting 5 years cuts $9,000 of contributions and $26,608 of final balance. To land at the same $64,608 from age 5 takes about $255 a month.

There is a floor on how early. NY 529's FAQ says you cannot open an account for an unborn child, because the beneficiary needs a Social Security Number or ITIN. It also says you can open one naming yourself, then change the beneficiary to the child once they have a number.

The 529 to Roth IRA rollover further down also runs on a 15-year clock, counted from how long the account has been open.

Should I have a 529 plan for each child?

Each account covers 1 kid. NY 529's FAQ: "there can be only one beneficiary named for each account," and separate accounts cover different beneficiaries.

1 account is not locked to 1 kid for good. IRS Publication 970 says changing the beneficiary to a member of the beneficiary's family has no income tax consequences, and its own example is a sibling.

Separate accounts can matter for the deduction. Maine's cap is up to $1,000 per beneficiary and Ohio's is up to $4,000 per beneficiary a year, so in those 2 states 2 kids means 2 caps.

Can I switch 529 plans?

Yes. Federal law lets you roll a 529 into another 529 for the same kid without tax, but only once in any 12 months. The statute's wording: it "shall not apply to any transfer if such transfer occurs within 12 months from the date of a previous transfer."

The catch to check first is your old state. New York's disclosure booklet says "Certain New York Nonqualified Withdrawals are also subject to recapture of any New York State tax benefits that have accrued on contributions." Other states have their own versions, and that recapture can eat the saving you were chasing. Which is a fun thing to find out afterwards.

There is also a size question. On a $5,000 balance, a 0.49 point fee gap costs about $168 over 5 years and $464 over 10. Pointing only future contributions at a new plan leaves the old balance where it is, so nothing leaves the old plan to be recaptured.

Paperwork matters when the money does move. NY 529's FAQ says the sending plan provides a breakdown of principal and earnings on a direct rollover, and without one, federal rules treat the whole rollover as 100% earnings.

What happens to a 529 if it is not used for college?

The plan choice still matters, because the fee comes out whether the money ends up at a university or not. The exit options are what change.

The simplest is a new beneficiary. IRS Publication 970 says changing it to a member of the beneficiary's family, a sibling for example, has no income tax consequences.

A scholarship softens the hit. Publication 970 says the extra 10% tax does not apply to a withdrawal included in income because the kid got a tax-free scholarship, up to the amount of the scholarship. Income tax on the earnings part still applies.

A 529 open for at least 15 years can roll into the kid's own Roth IRA through a direct transfer. It is capped at $35,000 over their lifetime, and each year at the Roth IRA limit ($7,500 for 2026) or the kid's taxable compensation, whichever is smaller, minus anything else they put in an IRA that year. Money added in the last 5 years does not qualify.

At the 2026 limit, moving the full $35,000 takes 5 separate years. California taxes these rollovers and adds its 2.5% on top. And because the yearly cap follows the Roth IRA contribution limit, the kid also needs at least that much taxable compensation in the year of each rollover.

A plain nonqualified withdrawal is the fallback. The earnings part is taxed as income and owes an extra 10% federal tax. We ran that side against the Trump Account in Trump Account or 529, and the long-run case for starting small is in your kid's dollar a day.

Does a state 529 deduction apply to a UTMA?

No. A UTMA is a taxable brokerage account with a custodial wrapper, so none of the state 529 deductions on this page reach it, and nothing you put in one is deductible anywhere.

The full comparison, with $150 a month run through both accounts for 18 years and a dollar figure on the tax and 4 years of aid, is in UTMA vs 529.

For how the 529 itself counts on the FAFSA, see does a 529 hurt financial aid. If your kid has earned income, we also ran custodial Roth IRA vs 529.

Frequently asked questions

Can I use another state's 529 plan?

Generally yes. New York's plan, for 1, says you do not have to be a New York resident to open one. You may lose your own state's deduction if it only covers the in-state plan.

Is a 529 plan tax deductible?

Not on your federal return. IRS Publication 970 says you cannot deduct 529 contributions. More than 30 states offer a state deduction or credit, with rules and caps that vary by state.

Which states have no 529 tax deduction?

4 states with a broad income tax offer none: California, Hawaii, Kentucky and North Carolina, per savingforcollege.com's table updated Sep 11, 2026. Delaware, Maine and New Jersey do have deductions.

Are advisor-sold 529 plans more expensive?

On average, yes. Morningstar's 2026 study puts advisor-sold plans at 0.79% and direct-sold plans at 0.30%, and says direct-sold plans come at a 62% discount. On $150 a month for 18 years, that gap costs about $3,167.

What happens to a 529 plan if it is not used?

The beneficiary can be changed to a member of the kid's family with no income tax, per IRS Publication 970. A 529 open at least 15 years can roll up to $35,000 into the kid's Roth IRA. Otherwise the earnings part is taxed as income plus an extra 10% federal tax.

Should I have a 529 plan for each child?

Each 529 account names only 1 beneficiary, per NY 529's FAQ, so each kid needs a separate account to be named. IRS Publication 970 says the beneficiary can be changed to a family member, such as a sibling, with no income tax consequences.

Can a 529 plan be converted to a Roth IRA?

Partly. A 529 open at least 15 years can roll into the beneficiary's Roth IRA, up to $35,000 over their lifetime. Each year is capped at the smaller of the IRA limit ($7,500 for 2026) or the beneficiary's taxable compensation, minus other IRA contributions. Contributions from the last 5 years do not qualify.

What happens to my 529 deduction if I move?

The account can stay where it is. NY 529's FAQ says you can keep contributing from anywhere, but once you are no longer a New York taxpayer you cannot deduct those contributions in New York.
