Minnesota has released a revision to Income Tax Withholding Instruction Booklet and Tax Tables.
The only change is to include affirmative instructions stating that payors of non-periodic distributions must request a Form W-4MNP from the payee. Form W-4MNP is a form to be completed by the payee and retained by the payor that enables payees to dictate the appropriate state withholding for non-periodic payments, including the option for the payee to waive state withholding.
