2026 North Dakota Homestead Property Tax Credit application based on 2025 income is due April 1, 2026 to the local assessor/county director.
Senior relief
North Dakota Homestead Property Tax Credit: homeowner age 65 or older or permanently and totally disabled, with preceding-calendar-year income no more than $70,000. For 2026, income $0–$40,000 reduces taxable value 100% up to $9,000 (maximum $200,000 true/full value); income $40,001–$70,000 reduces taxable value 50% up to $4,500 (maximum $100,000 true/full value). The 2026 application is due before April 1, 2026.
Valuation limits
North Dakota HB 1176 limits each taxing district's 2026 levy increase to 3% over the preceding levy without voter approval, subject to statutory adjustments/exceptions. Williams County also sends an assessor notice for an increase of at least $3,000 and more than 10%; that is a notice threshold, not a parcel valuation cap.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
