Minnesota Estimated Tax Payments (2026)

Do you have to pay estimated taxes in Minnesota?

Yes. If you're self-employed in Minnesota and expect to owe $500 or more in Minnesota income tax for 2026 after withholding, you must make quarterly estimated payments to Minnesota Department of Revenue. That is below the federal $1,000 threshold, so most part-time self-employed people owe them too. Minnesota taxes income at graduated rates up to 9.85%.

When are Minnesota estimated taxes due in 2026?

Minnesota's 2026 quarterly payments are due April 15, June 15, September 15, and January 15, in four equal installments, on the same calendar as your federal payments.

• Q1, April 15, 2026

• Q2, June 15, 2026

• Q3, September 15, 2026

• Q4, January 15, 2027

How much should you set aside for Minnesota estimated taxes?

Plan to set aside 25% to 30% of your net self-employment profit to cover federal and Minnesota taxes combined, then confirm the exact amount with the calculator above. On $50,000 of net self-employment profit, federal self-employment tax alone is about $7,065 (15.3% on 92.35% of your earnings). On top of that you'll owe federal income tax and Minnesota income tax at graduated rates up to 9.85%.

How do you avoid a Minnesota underpayment penalty?

To avoid a Minnesota underpayment penalty, pay the smaller of 90% of your 2026 Minnesota tax or 100% of your 2025 tax, or 110% of last year's tax if your prior-year AGI topped $150,000, in four on-time installments. Paying the full amount late doesn't help; each installment has to be on time. You can estimate a federal underpayment penalty here.

What deductions lower your Minnesota estimated taxes?

Because estimated taxes are based on your net profit, every business write-off you claim lowers what you owe each quarter. Common deductions for 1099 workers, reported on Schedule C, include the home-office deduction, car mileage, phone and internet, software, and supplies. Like the IRS, Minnesota lets you deduct half of your self-employment tax. The federal Qualified Business Income (QBI) deduction can remove up to 20% of your qualified business income from your federal taxes, but Minnesota doesn’t allow it, so it doesn’t lower your Minnesota tax.

How to file quarterly taxes in Minnesota

Filing quarterly in Minnesota means two separate payments each period: one to the IRS for federal tax, and one to the Minnesota Department of Revenue for your state taxes. Here’s how to do it.

1. Confirm you need to pay. You owe estimated payments when tax isn’t withheld from enough of your income — 1099 or freelance work, investment income, or other untaxed income. Federal and Minnesota run separate tests: the state generally requires estimated payments if you expect to owe $500 or more in Minnesota tax after withholding and credits, subject to its safe-harbor rules.
2. Calculate your federal estimate. Use the Form 1040-ES worksheet (or tax software). Estimate your full-year income, add your federal income tax and self-employment tax, subtract anything already withheld from a paycheck, and split the rest across the year. The estimate at the top of this page gives you a starting number.
3. Calculate your Minnesota estimate separately. Work out your Minnesota amount on its own using Form M15. Don’t just send part of your federal payment to the state — the Minnesota calculation is separate, based on your Minnesota income tax, credits, and any Minnesota withholding.
4. Pay the IRS. Pay through IRS Direct Pay (or EFTPS) and choose the estimated tax / Form 1040-ES option. Select tax year 2026 and save the confirmation number. This money counts only toward your federal taxes.
5. Pay Minnesota separately. Make a second payment to e-Services and select the Form M15 estimated payment for 2026. Save that confirmation too. This money counts only toward your Minnesota taxes.
6. Repeat on each deadline. For 2026, federal estimated payments are due April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027. Minnesota uses those same four dates.
