Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Williams County Assessor / Treasurer's Office.
Relief programs
The filing guidance for this county is: 2026 North Dakota Homestead Property Tax Credit application based on 2025 income is due April 1, 2026 to the local assessor/county director. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationNorth 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.
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.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: Williams County cities hold local equalization meetings within the first 15 days of April 2026 and organized townships meet during April; contact the Assessor by March 1 to learn the meeting date/time/place. Notice is required at least 15 days before a qualifying value increase. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
