Is the Indiana 529 benefit a deduction or a credit?

It is a tax credit, not a deduction. Indiana gives a credit equal to 20% of your CollegeChoice 529 contributions. Because it is a credit, the benefit is a flat 20% and does not depend on your marginal tax rate.

What is the maximum Indiana 529 tax credit?

The maximum credit is $1,500 per year for most filers, which you reach by contributing $7,500 (7,500 times 20% equals 1,500). For married couples filing separately, the cap is $750 on $3,750 of contributions.

Can I carry forward unused Indiana 529 credit?

No. The Indiana 529 credit is non-refundable and cannot be carried forward to a future year. It can reduce your Indiana tax to zero, but any credit beyond your tax liability is lost, so plan contributions around your tax.

Does the credit apply to out-of-state 529 plans?

The credit applies to contributions to the Indiana CollegeChoice 529 plan and certain CollegeChoice CD options. Contributions to another state's 529 plan generally do not qualify for the Indiana credit.

What if I contribute more than $7,500?

Contributing above $7,500 is allowed and still grows tax-free for education, but the Indiana credit is capped at $1,500, so extra contributions earn no additional state credit. The tool flags any amount above the cap.

Indiana is unusual in rewarding 529 savers with a tax credit rather than a deduction. Contribute to the CollegeChoice 529 plan and Indiana hands back 20 percent of what you put in, up to a yearly cap. This calculator shows the credit you earn and how much of it you can actually use.

How it works

The Indiana benefit is a flat-rate credit:

credit = 20% × eligible contribution
max credit = $1,500/year  (most filers)
max credit = $750/year    (married filing separately)

The cap means the credit tops out once you contribute 7,500 dollars (or 3,750 dollars if filing separately). The credit is non-refundable: it can wipe out your Indiana tax but cannot create a refund, and unused credit cannot be carried to next year. So the tool also limits the usable credit to your Indiana tax before credits.

Example

A single filer contributes 7,500 dollars to CollegeChoice 529 and owes 3,000 dollars of Indiana tax. The credit is 20 percent of 7,500, or 1,500 dollars — the maximum. Because their tax is 3,000 dollars, they can use the full 1,500-dollar credit, cutting their Indiana tax to 1,500 dollars.

Notes

The credit applies to the Indiana CollegeChoice plan; other states’ plans generally do not qualify. Contributions above the cap still grow tax-free for education but earn no extra Indiana credit. Verify current rules at in.gov/dor and the CollegeChoice 529 website.
