About the Assessor's Office

North Dakota law requires the Williams County Assessor's Office to uniformly and fairly value all parcels of land and buildings for tax purposes.

Property valuation is an ongoing process that consists of gathering and reviewing information on properties through field inspections, measuring and listing new construction, and analyzing market sales to determine fair values for existing and new construction properties. The office uses a Computer Assisted Mass Appraisal system to help fairly arrive at a true and full value for each property. Each year, a sales ratio is conducted to determine how close the assessor's values compare to sales and how equitable various types of property are being valued.

All real property subject to taxation is assessed as of February 1st of each year.  Any increase of assessment of $3,000 or more, and more than 10% in value, requires a "Notice of Increase" in assessment to be sent to the property owner.

Property taxes are determined by our elected officials (City & County Commissioners, school & park board members , etc.) setting a budget for their political subdivision.  That is what determines the total amount of property tax to be paid in any given year in Williams County. For information about property taxes, please visit the Property Information page.

Farm Residence Exemption

The 2019 Legislative Session brought several changes to the Farm Residence Exemption for those claiming Active Farmer Status (other designations have not changed). 

To qualify as an Active Farmer, the farmer and their spouse, if married, must have received more than 66% of their combined annual gross income from farming activities in any one year of the two preceding calendar years, whether one or both are farmers. This is a change from having made no more than $40,000 net off-farm income in each of the past 3 years.

The Active Farmer must now include the “Statement of Farm Gross Income” form in addition to their application. This form is available on the North Dakota Tax Commissioner’s website The form is a fillable Excel spreadsheet based off the current IRS 1040 form. The Farm Residence Application can be found on our Documents and Links page or picked up from the Assessor's Office.

Applications are due February 1 st ,   however the Statement of Farm Gross Income can be submitted separately before March 31 st . Applications are considered incomplete and will be denied if the Statement of Farm Gross Income is not received by the Assessor’s Office.
