An Act to limit annual valuation increases on owner -occupied single -family 1
dwellings and provide an exception for mill rate limitations on taxing 2
districts. 3
BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF SOUTH DAKOTA: 4
Section 1. The Legislature finds that the principles established in Nordlinger v. Hahn, 505 5
U.S. 1 (1992), affirm the constitutionality of basing property tax assessments on the purchase 6
price of property rather than current market value, for the purpose of protecting homeowners 7
from unexpected hikes and escalating real estate values impacting the reliance interests in 8
their homes. This Act is intended to stabilize property taxes for homeowners of this state, 9
while ensuring compliance with equal protection guarantees under the United States 10
Constitution. 11
Section 2. That § 10-6-105 be AMENDED: 12
10-6-105. All real property subject to taxation shall must be listed and assessed 13
annually, but the value of such the property is to be determined according to its value on 14
the first day of November preceding the assessment , while the value of any owner -15
occupied single-family dwelling is subject to the value limitations provided in sections 3 16
and 4 of this Act. 17
Section 3. That a NEW SECTION be added to chapter 10-6: 18
For purposes of the annual assessment required by § 10-6-105, the assessed value 19
of an owner -occupied single-family dwelling may not increase more than three percent 20
annually, beginning with the base amount as determined for assessment year 2026, or 21
any subsequent base year as provided in this section, whichever is later. 22
When a change in ownership of an owner -occupied single-family dwelling occurs, 23
the property must be reassessed at its fair market value, to determine the property's base 24

amount. When an owner -occupied single-family dwelling is sold between a willing seller 1
and a willing buyer, with no coercion or advantage taken by either party, the property's 2
base amount may not exceed the sales price of the property. 3
For purposes of this section, "base amount" means: 4
(1) The fair market value of any owner-occupied single-family dwelling, on November 5
1, 2020, increased by no more than three percent annually for each assessment 6
required by § 10-6-105, which was completed in 2021, 2022, 2023, 2024, and 7
2025; 8
(2) Where a change in ownership of an owner -occupied single -family dwelling has 9
occurred between November 2, 2020, and October 31, 2026, inclusive, the fair 10
market value of the property on the date of transfer or purchase, increased by no 11
more than three percent annually for any assessment required by § 10-6-105, 12
which was completed after the transfer or purchase in any year between 2021 and 13
2025, inclusive; or 14
(3) Where a change in ownership of an owner -occupied single-family dwelling occurs 15
on November 1, 2026, or later, the fair market value of the property. 16
Section 4. That a NEW SECTION be added to chapter 10-6: 17
The base amount of any owner -occupied single -family dwelling may be further 18
increased above the limitations provided by section 3 of this Act, if there is a change in 19
the use or classification of the property, or to account for any addition to, or expansion 20
of, the property. 21
An addition to, or expansion of, the property may result in an increase in the 22
assessed value above the limitations provided by section 3 of this Act, only by the 23
difference between the real property with the addition or expansion and the real property 24
as if no addition or expansion was made. 25
For purposes of this section, the increase in taxable value from improvements to 26
an owner-occupied single-family dwelling does not include additions to, or improvements 27
of, existing structures affixed to the land if the improvements result in an increased 28
valuation of forty percent or less of the current valuation. 29
