Paying Your Individual Income Tax
If you owe Minnesota income tax, your payment is due by the regular due date – April 15 for most people – even if you have an extension to file your federal return. If that date falls on a weekend or legal holiday, your payment is due on the next business day. For more information, see Due Dates for Filing Individual Income Tax.
If you owe tax on an amended return, your payment is due when you file the return.
