South Dakota's SB 96 allows counties to impose a 0.5% sales tax on taxable goods, digital products, and services (following state sales tax rules). All revenue from this county-level tax must go into a dedicated "property tax reduction fund." The fund is used to reduce property taxes on owner-occupied homes first, then agricultural and other land types, with all reductions applied equally across qualifying properties. Counties must adopt an ordinance to implement the tax and may hold a voter referendum on the proposal.
HB 1253 adjusts how property taxes are calculated for owner-occupied single-family homes and nonagricultural land by using a special averaging method. It requires county assessors to set each property's taxable value based on the "Olympic average" (removing the highest and lowest values) of its fair market value over the past eight years, or since a recent change in use or addition. This aims to stabilize tax bills by smoothing out annual value fluctuations. The bill specifically prevents this adjustment from increasing taxes on agricultural properties. It directly affects homeowners and nonagricultural property owners in South Dakota.
SB 220 directs South Dakota's Department of Corrections to conduct a study evaluating juvenile correctional and residential facilities. The study must examine best practices, therapeutic housing models, vocational training combined with mental health services, and staff-to-youth ratios, including inspections at three facilities outside South Dakota. The bill appropriates $50,000 from the general fund to cover study costs and requires a written report to the Legislative Research Council by September 1, 2026. This is a procedural study bill with no direct policy changes or new requirements for facilities, solely aimed at gathering information for future decisions.
SB 223 modifies South Dakota's process for school districts to refer excess tax levies to voter approval. It changes the petition signature requirement from a flat 50 voters to "at least five percent of the registered voters" in the school district. The bill also adjusts notice rules, waiving newspaper publication requirements if the district mails the resolution to all property taxpayers within 20 days. This affects school districts seeking voter input on tax increases and directly impacts local taxpayers who may petition to refer levy decisions.
This bill reduces property taxes for homeowners by lowering the mill levy rate on owner-occupied single-family homes from $5.21 to $20.51 per $1,000 of taxable value (with the exact figure clarified in the bill text). It simultaneously raises the state sales tax from 4.2% to 4.7% for 2026-2027 and to 5% after 2027, and expands the gross receipts tax to cover more services like dry cleaning, beauty shops, and rentals. The revenue from these tax increases is explicitly allocated to replace lost school district property tax revenue and fund pay raises for state and school employees. The bill ensures school districts maintain their total funding levels under the new system.
HB 1317 removes a 10% annual cap on how much South Dakota counties and municipalities can increase property taxes using accumulated unused index factors. Currently, local governments could only raise taxes based on these factors up to the prior three years' total or 10%, whichever was lower. The bill eliminates the 10% limit, allowing them to use all accumulated unused index factors from prior years without this restriction. This directly affects local governments' ability to adjust property tax revenue annually. The change modifies how county auditors calculate annual tax revenue limits under state law.
HB 1318 prohibits South Dakota from engaging with or investing in "natural asset companies," defined as for-profit entities that manage ecological resources like soil, biodiversity, or water quality for financial gain. The bill bans state contracts, investments, and bonds involving these companies, prohibits them from operating in the state, and voids any contracts entered after July 1, 2026. It also requires the Secretary of State to revoke business licenses for such companies and prevents natural assets (e.g., land, water rights) from being transferred to them. The law applies broadly to corporations and LLCs classified as natural asset companies but excludes state retirement systems and investment councils.
