Minnesota K-12 Education Credit and Subtraction: A Back-to-School Tax Guide

If you’ve been keeping the receipts from your back-to-school shopping trip in a junk drawer somewhere, don’t toss them. The Minnesota Department of Revenue sends out a reminder around this time every year encouraging families to hang on to those receipts, and there’s a good reason for it. Minnesota is one of the few states that offers a state-level tax benefit specifically tied to K-12 school expenses, and it comes in two separate forms: a refundable credit and an income tax subtraction. Let’s get into the details.

This post walks through both Minnesota benefits first, since they’re timely and directly tied to the shopping you’re doing right now. Then it moves into the federal picture for education costs, including the American Opportunity Tax Credit, the Lifetime Learning Credit, and how 529 plans interact with all of it. If you’ve got a mix of K-12 kids and a college student in the same household, or you’re just trying to figure out what applies to your family for the 2026 tax year, this covers the full landscape.

The Minnesota K-12 Education Credit: A Refundable Benefit With Income Limits

The K-12 Education Credit is the more valuable of Minnesota’s two benefits, because it’s refundable. That means if the credit reduces your tax liability below zero, the state sends you the difference as a refund rather than the excess simply disappearing. It’s also the more restrictive benefit, because it comes with household income limits.

For the 2026 tax year, your household income needs to fall under these thresholds to qualify:

$83,550 if you have one or two qualifying children in kindergarten through 12th grade
$86,550 if you have three qualifying children
$89,550, plus an additional $3,000 for each child beyond three, if you have more than three qualifying children

If your household falls under those thresholds, the credit itself is worth 75% of your qualifying expenses, capped at $1,500 per child. So if you spend $600 on qualifying supplies and tutoring for one child, the credit is worth $450 (75% of $600). Once a single child’s qualifying expenses reach $2,000, the 75% calculation would produce exactly $1,500, which is also the cap, so anything spent beyond $2,000 per child no longer increases the credit for that child.

Last year, more than 46,000 Minnesota families claimed this credit, with an average credit of $389. So if you qualify for this credit, you should absolutely take advantage of it!

The Minnesota K-12 Education Subtraction: No Income Limit, Smaller Per-Dollar Value

The subtraction works differently, and it’s the benefit more Minnesota parents qualify for, because there’s no household income limit attached to it.

Instead of a dollar-for-dollar credit against your tax bill, the subtraction reduces your Minnesota taxable income. That makes it less valuable per dollar of qualifying expense than the credit, since it only saves you a percentage of each dollar (whatever your marginal Minnesota tax rate happens to be) rather than a full dollar-for-dollar reduction. But because it isn’t income-limited, far more families end up using it. Over 123,000 Minnesota families claimed the subtraction, with an average subtraction of $1,491.

The subtraction amount depends on the child’s grade level: up to $1,625 per child in kindergarten through 6th grade, and up to $2,500 per child in 7th through 12th grade.

The same expenses can’t be counted for both the credit and the subtraction, you have to pick one lane or the other. If your income comfortably clears the credit’s threshold, that’s an easy call since the credit is worth more per dollar. But if you’re sitting close to that income cutoff, it’s worth running the numbers both ways, since a few hundred dollars of income can be the difference between qualifying for the credit at all and being stuck with just the subtraction.

What Counts as a Qualifying Expense for Both Minnesota Benefits

Both the credit and the subtraction draw from the same general category of qualifying expenses, and the list is broader than most parents expect. It’s not just tuition (private school tuition is actually excluded from the credit, though it can qualify for the subtraction in some circumstances). The expenses that consistently qualify for both benefits include:

Paper, pens, notebooks, and textbooks
Rental or purchase of educational equipment, such as musical instruments needed for a school band or orchestra class
Computer hardware and software your child uses at home for academic subjects, including a laptop, hotspot, modem, or router. This one has a combined cap of $400 in computer expenses across both programs, split as no more than $200 toward the subtraction and no more than $200 toward the credit. You can’t shift the full $400 onto just one of the two.
Fees paid for after-school tutoring and educational summer camps, as long as the instruction is provided by a qualified instructor

Like everything, there’s some nuance here. For example, Internet service fees do not qualify, even though the hardware that connects to the internet (the modem, the router, the hotspot device) does.

The child also has to meet the underlying eligibility requirements, which generally means attending kindergarten through 12th grade at a public, private, or qualified home school program, along with a few other qualifications specific to each benefit.

Keep Your Receipts Now, Not Next April

As with everything tax-related, you should save your receipts for anything that might be deductible. You may not be asked for the receipts, but if you are - you’ll be glad you kept them. Many of these expenses are costs you are incurring anyway, so save the receipts and get your deduction!

From K-12 to College: Where the Federal Credits Take Over

The Minnesota benefits above cover the school-supply-and-tuition-adjacent costs of raising a K-12 kid. If college is on the horizon instead, or in addition, a different set of federal credits comes into play, and they work completely differently.

The American Opportunity Tax Credit (AOTC)

The AOTC is generally the most valuable federal education credit for families with a student in the first four years of post-secondary education. For 2026, it’s worth up to $2,500 per eligible student, calculated as 100% of the first $2,000 of qualified education expenses plus 25% of the next $2,000.

Up to 40% of the AOTC, a maximum of $1,000, is refundable. That means even a family with little to no tax liability can receive up to $1,000 back as a refund from this credit, which makes it meaningfully more valuable than a purely nonrefundable credit for lower-income families.

The AOTC does phase out based on modified adjusted gross income (MAGI). For 2026, the phase-out range is $80,000 to $90,000 for single filers and $160,000 to $180,000 for married filing jointly. Above $90,000 (single) or $180,000 (joint), the credit isn’t available at all.

The credit is also limited to the first four years of post-secondary education per student, so if you’ve already claimed it for four prior tax years for the same student, it’s off the table for that student going forward. This gets a little weird timing-wise, since kids are usually in college for four school years, but they tend to cross over five tax years since school usually starts in the fall.

The Lifetime Learning Credit (LLC)

The Lifetime Learning Credit works differently, and it fills the gaps the AOTC leaves behind. It’s worth up to $2,000 per tax return, not per student, so a family with two kids in college simultaneously doesn’t get $2,000 for each one under the LLC the way they might under the AOTC’s per-student structure.

Unlike the AOTC, the LLC is entirely nonrefundable. It can reduce your tax bill to zero, but it won’t generate a refund beyond that. It also has no limit on the number of years you can claim it, which makes it useful for graduate school, part-time coursework, or continuing education that doesn’t fit the AOTC’s four-year, degree-track framework.

For 2025 and 2026, the full LLC is available up to $80,000 MAGI for single filers and $160,000 for married filing jointly, phasing out completely at $90,000 single and $180,000 joint for 2026.

One rule to know if you have multiple students in the household: you cannot claim both the AOTC and the LLC for the same student in the same tax year. You have to pick one or the other per student. But you can use the AOTC for one child and the LLC for another child in the same household in the same year, if your situation calls for it, such as one child in their first four years of a degree program and another pursuing a graduate certificate.

529 Plans and the “No Double-Dipping” Rule

529 plans remain one of the most efficient ways to save for education costs, because qualified withdrawals grow and come out entirely tax-free. But there’s a coordination rule that trips up a lot of families, and it’s worth flagging clearly.

Expenses paid using tax-free 529 distributions generally cannot also be used to claim the AOTC, the LLC, or Minnesota’s K-12 credit or subtraction, for that same dollar of expense. In practical terms, if you pull $4,000 out of a 529 account tax-free to cover tuition, you can’t turn around and also claim that same $4,000 toward the AOTC calculation (much like you can’t use Flexible Spending Account expenses as an itemized deduction). Families need to carve out enough non-529 dollars (savings, income, or other sources) to pay for the expenses they intend to use toward these credits, and use 529 funds for the remainder.

It’s also worth knowing that 529 plans aren’t limited to college. Federal law allows up to $10,000 per year in 529 distributions to cover K-12 tuition, which is a separate and distinct benefit from the Minnesota K-12 credit and subtraction covered earlier in this post. A family could, in theory, be using 529 funds for K-12 tuition while separately claiming the Minnesota credit or subtraction for supplies and tutoring paid with other money. The coordination just has to be intentional rather than assumed.

A Few Other Education Tax Items Worth Knowing

A handful of additional provisions round out the education tax picture, and while they aren’t the focus of this post, they’re worth a brief mention:

Student loan interest deduction: Up to $2,500 of student loan interest paid during the year is deductible above the line, meaning you don’t have to itemize to claim it. It phases out at higher income levels.
Employer education assistance: Employers can provide up to $5,250 per year in tax-free education assistance to employees, covering tuition, fees, and related costs, without that amount being added to the employee’s taxable wages.
Form 1098-T: If you or your student paid qualified tuition and expenses to an eligible post-secondary institution, you should receive a Form 1098-T from that school reporting the amounts paid. This form is generally the starting point for calculating both the AOTC and the LLC, so keep it with your tax documents when it arrives.

When to Get Professional Help

Most families can handle straightforward K-12 supply and tutoring expenses on their own, especially with good tax software that walks through the Minnesota credit and subtraction questions directly. Where it gets more complicated, and where professional guidance tends to pay for itself, includes:

Households near the Minnesota credit’s income thresholds, where a few hundred dollars of income could determine eligibility
Families claiming both the credit and the subtraction in the same year, where expenses need to be allocated correctly between the two
Households with both K-12 expenses and post-secondary costs in the same year, juggling Minnesota benefits alongside the AOTC or LLC
Anyone using 529 distributions who wants to make sure they’re not inadvertently double-dipping on the same expense dollars
Families with multiple college students, deciding how to split the AOTC and LLC most effectively across students

The Bottom Line

Minnesota’s K-12 Education Credit and Subtraction are two of the more underused tax benefits available to Minnesota families, largely because people don’t know the sorts of things that qualify. If you have kids in kindergarten through 12th grade, spent money this year on supplies, instruments, tutoring, or qualifying technology, and haven’t looked into these benefits before, it’s worth doing before you file your 2026 return. And if your family is also navigating post-secondary costs, the AOTC, the LLC, and your 529 plan all need to work together deliberately rather than by accident, particularly around the rule against using the same expense dollar for a 529 withdrawal and a tax credit.

Start with the receipts. Keep them organized as you go, not reconstructed from memory next April, and you’ll be in a much better position to claim what you’re actually entitled to.
