Rate Breakdown

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

How Property Tax Works in Brown County

Property taxes in Brown County are determined by the assessed value of your property multiplied by the local mill levy. The Brown County Director of Equalization is responsible for assessing all real property at its full and true market value as of November 1st of the preceding year. This assessment ensures that the tax burden is distributed equitably across the county based on current market conditions.

The mill levy—the tax rate expressed in dollars per $1,000 of assessed value—is set annually by local taxing jurisdictions, including the county, municipalities, and school districts. To calculate your estimated tax, the assessor applies the following formula: (Assessed Value x Mill Levy) / 1,000. Because mill levies fluctuate based on the budgetary needs of these local entities, your total tax obligation may change even if your property's assessed value remains stable.

Available Exemptions

South Dakota offers several property tax relief programs to assist eligible residents. These programs are designed to reduce the tax burden for specific demographics:

• Homestead Exemption: Provides a reduction in property taxes for owner-occupied primary residences.
• Senior Citizen and Disabled Persons Tax Freeze: Eligible seniors (age 65+) and individuals with disabilities may qualify to freeze the valuation of their home, effectively stabilizing their property tax liability.
• Disabled Veteran Exemption: Veterans with a service-connected disability rated as permanent and total may qualify for a significant reduction or exemption on their primary residence.
• Paraplegic Exemption: Specifically available for veterans or other individuals who have suffered the loss of use of both lower extremities.

Eligibility requirements, including income thresholds and residency duration, are strictly enforced. Residents are encouraged to contact the Brown County Treasurer’s office to verify current application deadlines and documentation requirements.

Payment Schedule & Deadlines

In South Dakota, property taxes are paid in arrears. Payments are due in two equal installments throughout the year:

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

If the first half is not paid by April 30th, the entire balance of the tax becomes delinquent. Failure to pay by these deadlines results in the accrual of interest and penalties at a rate established by state law. Continued delinquency may eventually lead to the issuance of a tax certificate and potential tax deed proceedings, which could jeopardize your property ownership. It is vital to ensure payments are postmarked or received by the Brown County Treasurer by the close of business on the due date.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate or exceeds its market value, you have the right to appeal. The process begins at the local level with the Local Board of Equalization, typically held in March. If you are dissatisfied with that outcome, you may appeal to the Brown County Board of Equalization. Should the issue remain unresolved, further appeals may be directed to the South Dakota Office of Hearing Examiners. You must provide clear evidence, such as recent appraisals or comparable sales data, to support your claim of an incorrect valuation.
