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.
SB 135 requires data center operators to pay all electricity costs associated with their facilities, preventing utilities from raising residential rates to cover these expenses (Section 3). It also prohibits tax exemptions for data centers (Section 5) and ensures local governments retain authority to regulate data center development (Section 4). The bill mandates data centers to report projected water usage to local providers and the Board of Water Management before operation, with annual reports on actual consumption (Sections 6-7), ensuring water allocation prioritizes residential and essential services. This directly affects data center operators, utilities, and South Dakota residents by limiting cost-shifting and protecting local resource management.
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.
HB 1086 appropriates $2.7 million from the general fund to the South Dakota Department of Corrections for a grant to a nonprofit organization. The nonprofit must provide trauma-informed programming - including leadership development and skills training - to both offenders and correctional staff at three specific state prisons: South Dakota State Penitentiary, Mike Durfee State Prison, and South Dakota Women's Prison. To qualify, the nonprofit must currently operate such programming at a state facility and plan to serve all three prisons, as verified by the Department of Corrections. Unspent funds by June 30, 2031, will revert to the state treasury.
SB 205 revises drone registration fees in South Dakota, charging 1.5% of purchase price for agricultural drones and 2% for all other drones. The collected fees fund a new "drone aviation fund" administered by the Board of Technical Education to support drone training grants at state technical colleges. This bill directly affects drone owners (especially agricultural users) by changing their registration tax rates and creating a dedicated funding source for drone industry workforce development. The fund will receive all drone registration fees and interest, with expenditures requiring annual budget approval. The bill does not apply to small unmanned aircraft systems covered under federal regulations.
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.
SB 18 repeals a requirement that banks add back to their South Dakota franchise tax base any bad debt deductions they claimed on federal tax returns but later determined were not actually worthless. This change eliminates the need for banks to adjust their state taxable income for "recovered" bad debts, potentially lowering their tax burden. The bill directly affects banks operating in South Dakota subject to the state's franchise tax on banking activities. It removes specific provisions in the tax code that previously mandated this adjustment for bad debt accounting.
This South Dakota House Concurrent Resolution (HCR 6009) urges Congress to repeal the federal estate tax. It directly affects farm and ranch families and generational family businesses, as their assets (like land and equipment) are often hard to sell quickly to pay the tax. The resolution highlights that the tax can force heirs to downsize or sell operations to cover payments, rather than allowing them to maintain family assets. The resolution is a formal request to Congress, not a law, and does not change existing tax policy.
