North Dakota filing notes
Do not model North Dakota as a simple flat-tax state. Many filers have part of their North Dakota taxable income in the 0% bracket, then 1.95%, with the 2.5% top rate applying only above the highest threshold. Homestead and other credits should be checked against current ND forms.
Common mistakes: Converting too much in one year; Not planning for tax bill.
