Your State May Tax What Washington Does Not

The federal rules for Trump accounts say, in a footnote, that they do not settle state tax. The Treasury Department wrote that treatment under any particular state law "depends on that law." That sentence is in the rules published September 30, 2026. This chapter covers what that could mean for your family.

We did not find a state page we could open and quote. So this chapter states no state's treatment as fact. It lists the questions to ask.

Why would a state differ from the federal rules?

Many states build their income tax on top of the federal tax code. Some follow new federal rules automatically. Some follow only the version of the code from a certain date. Some pick which parts to follow. A state that does not follow the part of the code that created Trump accounts could treat the account differently.

Treasury says it expects a state that follows the federal IRA trust rules would generally treat a Trump account the same way. It adds that each state's own law decides. So expecting the same treatment is a guess until your state says so.

What could a state do differently?

Three things are worth asking about.

1. Yearly growth. Federal rules do not tax growth until it comes out. A state that did not follow them could tax each year's growth as it happens.
2. Employer money. Federal law excludes up to $2,500 a year from your income. A state that did not follow could count it as wages.
3. Deposit breaks. Many states give an income tax break for 529 plan deposits. If your state has one for 529 plans and nothing for Trump accounts, the gap changes the comparison.

What would it cost in dollars?

These numbers are made up. The rates are not any state's. The tables show what each question could mean.

First, employer money. Say your employer adds the full $2,500 and a state counted it as wages.

Second, yearly growth. Say the account holds $10,000 and grows 7% in a year, which is $700. A state that taxed that growth would charge:

The amounts are small in one year. They repeat every year, and the employer case is tax on money that never showed up in your paycheck. We read no source saying any state does either.

What should you ask your state?

Use your state tax agency's website first. Search for "Trump account" or "section 530A." If nothing is posted, ask these questions by phone or email:

1. Does the state follow the federal rules that created Trump accounts?
2. Does it tax the account's growth each year, or only on withdrawal?
3. Does it count employer deposits as state wages?
4. Does it give any break for family deposits, like the one for 529 plans?
5. What happens if we move to another state later?
6. Does a child who owns an account need to file a state return?

Write down the date and who answered. Rules can change, and the federal rules are still being finished. The federal temporary rules took effect September 30, 2026. They end September 30, 2029, so what replaces them could change things again.

What does the federal rule cover, and what does it leave out?

The federal rules decide three things. Growth is not taxed until it comes out. Employer money up to $2,500 is excluded from your federal income. Your own after-tax deposits come back tax free.

The federal rules do not decide what your state does with any of the three. A state might follow all of them, some of them or none. The same family could get a clean federal result and a different state result in the same year.

How do you read the answer you get?

A good answer names the state rule or law, and it has a date. A reply like "we have not decided yet" is also an answer. Write it down. Then ask again before each year-end, because state positions can change as the federal rules are finished.

If the answer is unclear and the amount is small, you can still claim the federal $1,000. It costs you nothing. The state question matters most for employer money and for the money you add yourself.

How does this change your plan?

Do not freeze. Do not assume either. A half hour of asking costs less than a surprise tax bill.

• Employer plan: ask your state before enrolling, and ask your payroll team how the state treats it.
• Your own money: if your state gives a break for 529 deposits, add it to the comparison in the 529 chapter.
• The $1,000: the federal deposit costs you nothing. The state question is about growth and employer money, not about whether to claim it.

For very large amounts, hire a tax professional licensed in your state.
