Iowa 529 Tax Deduction 2026: up to $12,200 a year, worth about $464
Iowa takes money off your state tax bill when you put money into a 529 college fund for your child. Most parents never claim it — not because it's hard, but because nobody told them. Here's the whole thing in plain English.
What you can deduct
$6,100 ($12,200 married filing jointly) per year, per child. Fine print: per beneficiary, per account owner (2026 amount); ISave 529 only; contributions through the April 30 filing deadline count.
What it's worth
About 3.8 cents per dollar you contribute, up to the limit.
| You put in | Off your Iowa tax bill (≈) |

| $2,500 | $95 |
| $6,100 | $232 |
| $12,200 | $464 |
The trick: you don't need new money
If you pay for daycare, you probably qualify for federal tax breaks worth $1,000–$3,000 a year — the Dependent Care FSA at work and the childcare credit at tax time. Route that money into the 529 and Iowa pays you again for saving it. Same dollars, three tax breaks.

- Open the account (ISave 529 (Iowa), about 15 minutes; you'll need your and your child's Social Security numbers and a bank account).
- Contribute by the April tax deadline. Automatic monthly transfers are the easiest way — even $50 a month counts.
- Put it on your Iowa return. TurboTax and the others ask about 529 contributions in the state section; a tax preparer just needs your year-end statement.
Do I have to use Iowa's plan?
Yes — the deduction is only for contributions to Iowa's own plan, ISave 529 (Iowa).
Already have a 529 through Schwab, Fidelity, or Vanguard? Those are usually another state's plan, so Iowa gives you nothing for it. Keep that account, open ISave 529 (Iowa) for new contributions, and ask a tax pro before rolling the old balance over — some states don't count rollovers.
