Does Minnesota give a tax break for 529 contributions?

Yes. Minnesota lets taxpayers choose either a subtraction (deduction) of up to $1,500 for single filers or $3,000 for married filing jointly, or a refundable credit worth up to $500. You take one or the other, not both.

How does the Minnesota 529 credit phase out?

The refundable credit is worth 50% of contributions up to $500, but it phases down as household adjusted gross income rises above roughly $80,000 and is fully phased out at higher incomes. The deduction has no income limit but a lower cap.

Should I take the deduction or the credit?

Lower-income households usually benefit more from the refundable credit because it directly reduces tax dollar-for-dollar and can produce a refund. Higher earners past the credit phase-out generally take the subtraction instead.

Do I have to use the Minnesota state plan?

No. Minnesota allows the deduction or credit for contributions to any state's qualified 529 plan, not just the Minnesota College Savings Plan, as long as you are a Minnesota taxpayer.

Are 529 withdrawals taxed in Minnesota?

Qualified withdrawals used for eligible education expenses are free of both federal and Minnesota income tax. Non-qualified withdrawals may owe tax and a penalty on the earnings portion and may require recapturing prior state benefits.

Minnesota is unusual in offering taxpayers a choice between a deduction and a refundable credit for 529 college savings contributions. This calculator estimates your savings under both paths so you can pick the larger benefit.

How it works

The tool computes both Minnesota options on your contribution and compares them:

deduction savings = min(contribution, cap) × marginal rate
   cap = $1,500 single / $3,000 married filing jointly
credit = 50% × contribution, up to $500, reduced as income exceeds the phase-out
benefit = the larger of the two

The subtraction has no income limit but a lower cap, while the refundable credit is worth more at lower incomes and shrinks to zero as household income climbs.

Example

A married couple with a 5% marginal rate contributing $4,000 could subtract $3,000 for about $150 in tax savings, or — if their income is under the phase-out — claim a $500 refundable credit. The credit wins here, so the tool flags it as the larger benefit.

Notes

Estimate only, not tax advice. You may claim either the subtraction or the credit for a given year, not both. The credit phases out as adjusted gross income rises; exact thresholds adjust over time. Confirm current limits at revenue.state.mn.us.
