Rate Breakdown

Property taxes in Williams County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Williams County

Property taxes in Williams County are determined by a combination of the assessed value of the real estate and the millage rates set by local taxing jurisdictions. The assessment process begins with the County Assessor determining the "market value" of a property, which is the price the property would likely sell for in an open market. This value is then adjusted to an "assessed value" based on North Dakota state guidelines.

The actual tax amount is calculated using millage rates. A "mill" represents one-tenth of one percent of the assessed value. Because Williams County is divided into various taxing districts—including city, township, school, and county levels—your total millage rate is the sum of all applicable levies for your specific location. This ensures that tax revenue is distributed to support local infrastructure, emergency services, and public education.

Available Exemptions

North Dakota offers several programs to reduce the tax burden for eligible homeowners. While specific eligibility requirements may vary, common exemptions and credits include:

• Homestead Credits: Designed to provide relief to primary residents, these credits reduce the taxable value of a homeowner's principal residence.
• Senior Citizen Exemptions: Qualified seniors may be eligible for property tax relief or freezes to ensure housing affordability during retirement.
• Disabled Veteran Exemptions: Veterans with service-connected disabilities may qualify for significant reductions or full exemptions on their property taxes, depending on the degree of disability.
• Disability Exemptions: Certain individuals with permanent disabilities may apply for tax relief to lower their annual obligations.

Payment Schedule & Deadlines

Property taxes in Williams County are typically billed annually, but payments can often be split into installments. It is critical to adhere to the following guidelines to avoid financial penalties:

• Deadlines: Tax statements are generally mailed in the fall. Payments are typically due in full or in scheduled installments throughout the year.
• Installment Options: Homeowners may choose to pay in a single lump sum or utilize a payment plan offered by the county treasurer.
• Late Consequences: Failure to pay by the deadline results in interest charges and potential penalties. If taxes remain unpaid for an extended period, the property may be subject to a tax sale.

Appealing Your Assessment

If you believe your property has been overvalued, you have the right to appeal the assessment. To begin this process, you must file a formal notice of appeal with the Williams County Board of Equalization within the designated window—typically early in the calendar year. You will be required to provide supporting evidence, such as recent appraisals or sales data of comparable properties in your neighborhood, to justify a lower valuation.
