Rate Breakdown

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

How Property Tax Works in Bon Homme County

In Bon Homme County, property taxes are determined by a combination of the property’s assessed value and the local mill levy. Each year, the County Director of Equalization determines the "full and true" market value of your property. By state law, this assessment is intended to reflect the current market value of your home or land. Once the value is established, it is multiplied by the local tax rate, known as the mill levy.

The mill levy is the aggregate of rates set by various taxing entities, including the county, municipalities, school districts, and special purpose districts. Because these entities have different budgetary needs, the total mill levy fluctuates annually. Your final tax bill is calculated by taking your property's assessed value, multiplying it by the total mill levy, and dividing by 1,000.

Available Exemptions

South Dakota offers several property tax relief programs designed to assist eligible residents. These programs are governed by state statute and administered at the county level:

• Homestead Exemption: Generally applies to owner-occupied primary residences, often providing a lower assessment rate compared to commercial or non-owner-occupied properties.
• Senior Citizen and Disabled Persons Tax Freeze: This program freezes the valuation of a primary residence for residents who meet specific age (65+) or disability requirements and income thresholds.
• Disabled Veterans Exemption: Veterans who have a service-connected disability rated as 100% permanent and total, or who receive compensation at the 100% rate due to individual unemployability, may be eligible for a significant reduction in property taxes on their primary residence.

It is recommended that you contact the Bon Homme County Treasurer’s office to confirm eligibility criteria and application deadlines for these programs.

Payment Schedule & Deadlines

Property taxes in Bon Homme County are collected on an annual basis, though they may be paid in two installments. The statutory deadlines are as follows:

• First Half: Due by April 30th.
• Second Half: Due by October 31st.

If the first half is not paid by the April 30th deadline, the entire annual tax amount becomes delinquent. Payments made after these dates are subject to statutory interest penalties, which accrue monthly until the balance is satisfied. To avoid penalties, ensure your payment is postmarked or received by the Treasurer’s office on or before the due date.

Appealing Your Assessment

If you believe the assessment of your property is inaccurate, you have the right to appeal. The process begins with an informal review with the Bon Homme County Director of Equalization. If the issue remains unresolved, you may formally appeal to the Local Board of Equalization, followed by the County Board of Equalization. Should you remain dissatisfied, further appeals may be made to the South Dakota Office of Hearing Examiners. Documentation, such as recent appraisals or evidence of comparable sales, is essential for a successful appeal.
