Assessment Appeal

Property Assessment Appeal

All property in the state of South Dakota is to be assessed annually, with notice of assessed value mailed on or by March 1st. This annual assessed value is to be reflective of the full and true market value for all non-agriculture classed property. Meaning that all non-agricultural property is to be valued at the amount it would most reasonably sell for on the open market.

Each year, it is the right of any property owner to review the assessed value and appeal that value if it is greater than what the property would most reasonably sell for or is assessed unequally in relation to similar properties. An assessment appeal is an argument regarding the accuracy and equality of assessment, not a complaint about the tax amount.

Deadlines for the period to appeal property values are set by statute (SDCL 10-11-16, SDCL 10-11-23). Location of the property, either within a city/municipality or outside of a city/municipality, determines the appropriate level and deadline for appeal.
