Senior relief
North Dakota Homestead Property Tax Credit: a homeowner age 65 or older or permanently and totally disabled, living at and invested in the homestead, with preceding-calendar-year income no more than $70,000, may qualify. Income of $0–$40,000 receives up to a $9,000 taxable-value reduction (maximum $200,000 true/full value); income of $40,001–$70,000 receives up to a $4,500 taxable-value reduction (maximum $100,000 true/full value). North Dakota also provides a disabled-veteran property-tax credit.
Valuation limits
No general annual parcel-value cap was verified. North Dakota assesses real property at true and full value as of February 1 each year; assessed value is 50% of true/full value and residential taxable value is 9% of assessed value. Statutory levy limits and tax credits are not a general valuation cap.
