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 69 appropriates $5 million from the general fund to the South Dakota Department of Public Safety for purchasing a new Highway Patrol airplane, related mission equipment, and installation. This bill directly affects the Highway Patrol division by funding equipment upgrades for aerial operations. The key mechanism is a specific budget allocation with a requirement that unspent funds revert per state procedures. The bill also declares an emergency to allow immediate implementation upon approval.
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.
HB 1134 appropriates $101 from South Dakota's general fund to support state economic development efforts. The bill authorizes the state to approve payments for these purposes and requires unspent funds to revert per standard state procedures by June 30, 2026. This is a simple fiscal appropriation with no new programs or direct impact on specific entities beyond state budget allocations.
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.
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.
HB 1005 exempts sales and use taxes on data center equipment and software for businesses operating qualified data centers in South Dakota. It specifically covers servers, cooling systems, power infrastructure, security systems, and related technology used in facilities meeting strict criteria (e.g., built between 2026-2036, meeting fire safety standards). Qualified businesses must verify eligibility with the Department of Revenue and maintain compliance with electric utility agreements and water usage requirements. The tax exemption lasts 50 years from the facility's construction permit date. This directly affects data center operators seeking to reduce operational costs in South Dakota.
