Instructions for Above Worksheet
Step 1
Complete lines 1 through 11 of Schedule AI of federal Form 2210 using these modifications. 
•  Use your Minnesota Itemized deductions on line 4 of Schedule AI
•  Use your Minnesota standard deduction on line 7 of Schedule AI
•  Enter zero on line 9
Step 2
Using the amounts from line 2 of Form M1, Individual Income Tax, determine your Minnesota additions for each period. Enter the total 
amounts in step 2.
Step 4
Using the amounts from lines 5 through 7 of Form M1, determine your Minnesota subtractions for each quarter.
Step 6 — Minnesota Alternative Minimum Tax
If the Minnesota alternative minimum tax applies, determine the amount of Minnesota alternative taxable income for each period. Multiply 
that amount by the appropriate multiplier shown on line 2 of Schedule AI of federal Form 2210. From the resulting annualized alternative 
minimum taxable income, subtract the appropriate minimum amounts depending on the filing status ($92,710 for Married Filing Jointly or 
Qualifying Surviving Spouse, $46,360 for Married Filing Separately, or $69,530 for Single or Head of Household) and multiply the difference 
by 6.75% (.0675). 
If the result is more than the regular tax shown on step 6, replace the regular tax with the Minnesota alternative minimum tax. See Schedule 
M1MT for instructions on figuring the Minnesota alternative taxable income.

2024 Schedule M15 Instructions
Underpayment of Estimated Income Tax for Individuals (Form M1)

Do I need to file Schedule M15?
Use Schedule M15, Underpayment of Estimated Income Tax, to determine if you owe a penalty for underpaying estimated tax.
You may owe an underpayment penalty if you have $500 or more of Minnesota income tax due on income you received in 2024 after subtract-
ing these:
•  Minnesota income tax withheld from your income, plus any Minnesota estimated tax payments made
•  2024 refundable credits you are eligible for and claim (including the Child and Dependent Care, Child and Working Family, K-12 Education, 
  Parents of Stillborn Children, Refundable Credit for Tax Paid to Wisconsin, and Historic Structure Rehabilitation credits)
You do not have to pay an underpayment penalty if all of these apply:
•  You did not have a Minnesota tax liability on line 17 of your 2023 Form M1, Individual Income Tax
•  You were a Minnesota resident for all of 2023
•  Your 2023 return covered a 12-month period
Nonresidents and part-year residents. Determine your required annual payment based on your Minnesota assignable adjusted gross income.
Farmers and commercial fishermen. If you filed Form M1 and paid your entire income tax by March 1, 2025, or paid two-thirds of your 
income tax by January 15, 2025, you do not have to complete this schedule. You are considered a farmer or commercial fisherman if you earn 
at least two-thirds of your annual gross income by farming or commercial fishing.

Exceptions to the Penalty
If the IRS does not require you to pay additional charges for underestimating your federal tax because you are newly retired or disabled, or 
because of a casualty, disaster, or other unusual circumstances, do not complete Schedule M15. Include a copy of your federal request with 
your Form M1.

How do I avoid the penalty?
To avoid an underpayment penalty of estimated tax, you must have had Minnesota withholding or made the required, timely estimated tax pay-
ments and paid the lesser of:
•  90% of your current year’s original tax liability (66.7% if you are a farmer or commercial fisherman)
•  100% of your prior year’s total tax liability (110% if your federal adjusted gross income is more than $150,000)
If you are a nonresident or part-year resident, you must have had at least $1 of Minnesota tax liability to use 100% of your prior year’s tax.

Fiscal Year Taxpayers 
If you file your Minnesota return on a fiscal year basis, change the payment due dates to the 15th day of the fourth, sixth and ninth months of 
your fiscal year, and the first month of your next fiscal year.

Line Instructions
Although these instructions refer to your original return, both of these are also considered an original return:
• An amended return you filed by the due date of your original return
• A joint Form M1 replacing previously filed separate returns
Line 5
If you did not file a 2023 return, or it did not cover the full 12-month period, skip line 5 and enter the amount from line 4 on line 6.
Enter the amount from line 17 of your 2023 Form M1, unless your 2023 federal adjusted gross income (from line 11 of federal Form 1040) was 
more than $150,000. If you are a nonresident or part-year resident, use your adjusted gross income assignable to Minnesota.
If your 2023 federal adjusted gross income was more than $150,000, multiply line 17 of your 2023 Form M1 by 110%.
Optional Short Method or Regular Method
You may use the optional short method only if either of these apply:
•  You did not make any estimated tax payments (or your only payments were from Minnesota income tax withheld from your wages)
•  You paid your 2024 estimated tax in four equal amounts on or before the due date of each installment
Note: If you made any payment before the installment due date, it is best to use the regular method. Using the short method will cause you to 
pay a larger penalty than the regular method. If your payment was only a few days early, the difference will likely be small. Continue with line 
7 to use the optional short method. 
If you are not eligible or choose not to use the optional short method, use the regular method to determine your underpayment penalty. Skip 
lines 7–12 and continue with line 13.

Optional Short Method
Line 7
Enter the total amount of 2024 estimated tax payments you made in 2024 and 2025. Do not include any other amounts on line 7.

                                                                                                                                        Continued

Line 12
Subtract line 11 from line 10. This is the amount of your underpayment of estimated tax penalty. Enter this amount on line 27 of your 2024 
Form M1. If you owe an amount on line 26 of Form M1, add the penalty on line 12 of this schedule to the amount owed and replace line 26 
of Form M1 with the total. If you have a refund on line 24 of Form M1, subtract the penalty on line 12 of this schedule from your refund and 
replace line 24 of Form M1 with the result.

Regular Method
Complete column A, lines 13–16. Then, depending on whether you have an underpayment or an overpayment, either continue with line 17 of 
column A (underpayment) or line 13 of column B (overpayment).
Line 13
Enter 25% (.25) of line 6 in each of the four columns on line 13, unless one of these conditions applies:
1 Your taxable income was higher at some times during the year and lower at others.
  You may benefit by figuring your installments using the annualized income installment method. Complete the worksheet on the back of 
Schedule M15.
  The annualized income installment worksheet automatically selects the smaller of the annualized income installment or the regular install-
ment (increased by the amount saved by using the annualized income installment method in figuring earlier installments).
  If you use this method for one payment due date, you must use it for all payment due dates. Follow the worksheet instructions on the back of 
Schedule M15.
2 You are a farmer or commercial fisherman and did not pay your entire income tax by March 1, 2025, or did not pay two-thirds of your income 
tax when you paid your estimated tax by January 15, 2025.
  Enter the full amount of line 6 under column D of line 13 and omit columns A, B and C of line 13.
Line 14
For each payment period, enter the total of these:
•  Estimated payments you paid for each payment period. If you applied a 2023 refund to your estimated tax, it is considered an estimated pay-
ment for your first payment period.
•  Minnesota income tax withheld during 2024. You are considered to have paid Minnesota withholding evenly during the year unless you show 
otherwise. If you were employed all year, divide the amount from line 20 of Form M1 by four. Include the result in each column.
•  Your 2023 income tax refund, if you elected on your 2023 Minnesota return to apply all or a portion of your refund to your 2024 estimated 
tax
•  Any refundable credits you are eligible for and claim. You are considered to have received refundable credits evenly during the year unless 
you show otherwise. Divide the amount from line 18 of Form M1 by four, and include the result in each column.
You are considered to have paid any Minnesota income tax withheld or received any refundable credits (Child and Dependent Care, Working 
Family, K–12 Education, Parents of Stillborn Children, Credit for Taxes Paid to Wisconsin, or Historic Structure Rehabilitation) evenly during 
the year unless you show otherwise. If you worked all year, divide the total amount of withholding and credits by four, and enter the result in 
each column. Your 2023 refund that you applied as an estimated payment, if any, is considered a credit to your first payment period.
If you filed your 2024 Minnesota return and paid the tax you owed on or before January 31, 2025, you may consider the tax paid as of January 
15, 2025.
Lines 15 and 16
Compare line 13 of each column to line 14 of the same column. 
If line 14 is more than line 13, you have an overpayment for the payment period. Subtract line 13 from line 14 and enter the result on line 15. 
Add line 15 to the credit on line 14 of the next column. If you have an overpayment in any quarter following an underpayment, you must first 
apply it to previous underpayments.
If line 14 is less than line 13, you have an underpayment for that payment period. Subtract line 14 from line 13 and enter the result on line 16. 
Continue with line 17.
Line 17
If you have an underpayment in all four quarters, enter the date you filed your return or April 15, 2025 (whichever is earlier) in each column.
Otherwise, enter the date you paid your underpayment on line 16 in full. 
Example: You made your first quarter estimated tax payment on April 20, but you show an underpayment on line 16. On June 14, you paid your 
second quarter payment in full and included the underpayment from the first quarter. On line 17, you would enter June 14 in the first and second 
quarter columns.
Line 22
Add the amounts on line 21, columns A–D and enter the result on line 22. This is the amount of your underpayment of estimated tax penalty.
Enter this amount on line 27 of your 2024 Form M1. If you owe an amount on line 26 of Form M1, add the penalty on line 22 of this schedule 
to the amount owed and replace line 26 of Form M1 with the total. If you have a refund on line 24 of Form M1, subtract the penalty on line 22 
of this schedule from your refund and replace line 24 of Form M1 with the result.
