Property tax revenue is the principal source of funding for school districts and city and county government entities that provide public services across South Dakota. Property assessment and tax billing in the state is administered at the county level. In 2015, statewide property tax revenue amounted to nearly $1.2 billion. School districts collected about 56.7% of the total revenue, while counties took 26.5%, municipalities took 13.2% and townships took 1.7%. The remaining 1.9% went to special assessment districts for spending on local capital projects and related investments.

South Dakota Property Tax Basics

Residential and commercial property in South Dakota is assessed at full market value as determined by the county director of equalization on Nov. 1 each year. The taxable value of a property is set at 85% of its assessed value. This valuation applies to tax assessments taking place in the following calendar year. Actual tax payments are then due one year later. Thus, a property valuation on Nov. 1, 2016 applies to tax assessments in 2017, which then become payable on Jan. 1, 2018. One half of the property tax bill is due no later than May 1, while the remainder is due no later than Nov. 1.

Most South Dakota homeowners are eligible to pay a reduced rate for the portion of property tax going to the local school general fund. To get the reduced rate, a property must be the principal residence of the owner, who must also submit a certification form to the local county director of equalization. Once an owner-occupied dwelling is certified, it remains so until the property is sold or the owner-occupant moves. Residential property not certified as owner-occupied is subject to the same tax rate as commercial property and utility property. Agricultural property is a separate category of property assessed under a special productivity-based valuation system. Agricultural property has a lower property tax burden than other property in the state.
