How Property Tax Works

Marshall County, South Dakota operates on a property tax system that serves as the primary funding mechanism for essential local services including schools, roads, law enforcement, and county government operations. The county utilizes an effective tax rate of approximately 0.50% as of the 2025 levy year, though this represents a base rate that can vary significantly depending on your specific location within the county.

Property owners should note that actual tax rates differ across Marshall County due to special taxing districts such as school districts, fire districts, water districts, and municipal improvement districts. These additional assessments are layered on top of the base county levy, meaning two properties with identical assessed values may have different tax bills based on which special districts serve their area. The county assesses property at its full market value without a state-imposed assessment cap, making Marshall County's tax calculation relatively straightforward compared to other jurisdictions.

Supplemental Tax Bills

Supplemental taxes in Marshall County are additional property tax bills issued when significant changes occur to a property after the annual assessment date but before the tax year ends. Common triggers include new construction completion, major home additions or improvements, ownership transfers that reveal previously unrecorded improvements, or corrections to assessment errors.

The supplemental tax is calculated by applying the current year's tax rate to the difference between the old and new assessed values, prorated for the portion of the tax year remaining. For example, if you complete a $100,000 home addition in January and the county discovers it during a March inspection, you would owe supplemental taxes on that $100,000 increase (at roughly $500-610 based on current rates) prorated for 9-10 months depending on the assessment timing. Supplemental tax bills are typically issued within 30-60 days of the assessment change and have the same payment terms as regular property tax bills.

Escrow & Property Taxes

Most mortgage lenders in Marshall County require property tax escrow accounts for loans exceeding 80% loan-to-value ratio. Your lender collects 1/12th of your estimated annual property tax with each monthly mortgage payment, depositing these funds into an escrow account. The lender then pays your property taxes directly to Marshall County on the April 15th and October 15th due dates.

Lenders must provide an annual escrow analysis showing projected taxes, actual payments made, and any account surplus or shortage. Due to Marshall County's semi-annual payment schedule, your escrow account needs sufficient funds by early April and early October. If your property taxes increase due to reassessment or new special district levies, your lender will adjust your monthly escrow payment accordingly. Property owners can verify their tax payments were received by checking the Marshall County Treasurer's online portal or calling (605) 448-5220. Always review your mortgage servicer's escrow analysis against actual county tax records to ensure accuracy.
