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 Sioux County Tax Equalization / County Treasurer.
Relief programs
The filing guidance for this county is: 2026 Homestead Property Tax Credit application based on 2025 income is due April 1, 2026 to the local assessor/county director; general property-tax exemption applications are due February 1, 2026. 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. Income $0–$40,000: taxable value reduced 100% up to $9,000 (maximum $200,000 true/full value); income $40,001–$70,000: 50% up to $4,500 (maximum $100,000 true/full value). The 2026 application is due before April 1, 2026; North Dakota also provides a disabled-veteran credit.
North Dakota HB 1176, signed May 17, 2025, limits each taxing district's property-tax levy increase to 3% over the preceding levy without voter approval, subject to statutory adjustments and exceptions, effective for 2026 levies. This is a levy limitation, not a general parcel valuation cap; no separate general parcel valuation cap was identified in official North Dakota sources reviewed.
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: For 2026 assessments, city/township Boards of Equalization meet in April and the county Board of Equalization meets during the first 10 days of June; assessment-increase notice must be delivered at least 15 days before the local meeting. Exact county hearing/protest date was not published; contact the county Director of Tax Equalization. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
