In North Dakota, you'll face federal withholding of 24% on prizes over $5,000, plus state income taxes up to about 10.6% depending on your total income, with no local taxes applied to lottery winnings. Federal taxes can ultimately reach 37% in the highest brackets when you file your return, while North Dakota treats winnings as ordinary income subject to its progressive tax rates ranging from 1.1% to 10.6%. The initial withholding covers part of your liability, but you may owe more or get a refund based on deductions and credits. For a $1 million prize, expect around $240,000 federal withholding and roughly $80,000 to $100,000 in state taxes after filing, leaving you with less than anticipated. Always consult a tax professional for your specific situation, as rates and rules can change.
