Closing Date Prorations in South Dakota
In South Dakota, property tax prorations at closing are governed by the statutory rate set in S.D. Codified Laws § 10-21-4. This law establishes the method for determining the seller’s and buyer’s respective shares of the annual property tax when ownership transfers mid-year. The rule applies a fixed percentage to calculate the tax due for the portion of the year the seller owned the property. The exact formula and any applicable exceptions are detailed in the statute and the official source from the Department of Revenue. A worked example showing how this calculation operates is provided below. To estimate a specific closing proration, use the DocketMath calculator.
