South Dakota State Taxes Guide

South Dakota is unique among U.S. states because it does not levy a state income tax, making it an attractive place for individuals and businesses seeking to reduce their overall tax burden. Unlike most states, South Dakota does not require residents to file personal income tax returns, which simplifies tax obligations significantly. Additionally, there is no corporate income tax, meaning businesses, including small enterprises and large corporations, enjoy significant tax advantages when operating in the state. However, it is important to note that while South Dakota lacks income taxes, it does rely heavily on sales taxes, property taxes, and various other forms of local taxation to fund its public services and infrastructure. These taxes, though relatively modest, play a crucial role in generating the revenue needed to support the state’s economy, including education, public safety, transportation, and healthcare. Understanding South Dakota’s tax structure is vital for individuals and businesses looking to maximize tax efficiency while adhering to local tax requirements.

Sales Tax in South Dakota

One of the primary sources of revenue for South Dakota is its state sales tax. The state imposes a general sales tax of 4.5% on most goods and services sold within its borders. This tax applies to tangible personal property as well as certain services, such as repair, maintenance, and lodging services. In addition to the state sales tax, local governments in South Dakota, including cities and municipalities, are allowed to levy their own municipal sales taxes, which typically range between 1% and 2%. These local sales taxes are added on top of the state’s base rate, meaning that consumers in some areas of the state may pay a combined sales tax rate of up to 6.5% or higher.

South Dakota also applies its sales tax to internet sales and other forms of remote sales, following the landmark South Dakota v. Wayfair, Inc. Supreme Court decision in 2018. This ruling allowed the state to collect sales tax from out-of-state businesses selling goods or services to South Dakota residents, even if the business does not have a physical presence in the state. The Wayfair decision significantly increased South Dakota’s sales tax revenue, especially as e-commerce has become more prevalent. Businesses making more than $100,000 in sales or conducting 200 or more transactions annually with South Dakota residents must comply with this requirement and remit sales tax to the state.

South Dakota Use Tax

In addition to the sales tax, South Dakota also enforces a use tax, which applies to goods or services purchased outside the state but used within South Dakota. If a consumer buys an item from a state with a lower sales tax rate or no sales tax at all, they are required to pay South Dakota’s use tax to make up the difference. The use tax rate is the same as the state sales tax, 4.5%, and is designed to prevent residents and businesses from avoiding sales tax by making purchases in other states.

South Dakota Property Tax

Though South Dakota lacks income taxes, it does collect revenue through property taxes, which are levied by local governments, including counties, cities, and school districts. Property taxes are assessed based on the value of real estate, including land and buildings, and are used primarily to fund public schools, infrastructure projects, law enforcement, and other essential local services. South Dakota’s property tax system is known for its relative simplicity compared to other states, as there are fewer types of property classifications and exemptions.

Property tax rates vary by location and are typically expressed as a mill rate, which represents the amount of tax per $1,000 of assessed property value. For example, a mill rate of 20 would mean that for every $1,000 of assessed property value, $20 in taxes would be owed. The state does impose a property tax cap, which limits the amount by which local governments can raise property taxes each year. This cap helps prevent property taxes from rising too quickly and keeps the overall tax burden manageable for property owners.

South Dakota Business Taxes and Fees

While South Dakota does not impose a corporate income tax, it does require certain businesses to pay business-related taxes and fees. For example, businesses involved in industries such as banking and financial institutions are subject to the state’s bank franchise tax, which is based on the institution’s net income from conducting business in South Dakota. The bank franchise tax rate varies, with a maximum rate of 6%. This tax applies to banks, savings and loan associations, and other similar entities, making it one of the few industry-specific taxes in South Dakota.

Additionally, businesses in South Dakota must pay license fees, depending on the type of business activity they engage in. For example, businesses that sell alcohol, tobacco, or operate gaming establishments must obtain the appropriate licenses and pay the corresponding fees. While these fees are generally modest, they do contribute to the state’s overall tax revenue.

South Dakota Excise Taxes

South Dakota also collects various excise taxes on specific goods and services. One of the most notable excise taxes is the motor vehicle excise tax, which is applied when vehicles are purchased or transferred within the state. The excise tax rate for vehicles is 4% of the vehicle’s purchase price. Additionally, South Dakota imposes excise taxes on products like alcohol and tobacco, as well as certain energy and utility services. These excise taxes are typically passed on to consumers and help fund infrastructure projects and public services.

South Dakota Local Taxes and Fees

Beyond the state-level taxes, many municipalities and counties in South Dakota impose their own local taxes and fees. These can include local sales taxes, as previously mentioned, as well as tourism taxes, lodging taxes, and restaurant taxes. These local taxes are generally used to support city or county-level services, including parks, road maintenance, and local tourism promotion. Certain cities, particularly those with large tourism industries, may rely heavily on these taxes to fund local services. For example, the city of Deadwood imposes a special gaming tax on casinos, which is an important source of revenue for the local government.

South Dakota Tax Incentives and Rebates

South Dakota offers various tax incentives and rebates to encourage economic development, attract businesses, and stimulate growth in certain sectors. For instance, the state has programs that offer sales tax refunds for businesses investing in large capital projects or expanding operations. These incentives are designed to make South Dakota a more attractive place for business investment and can be particularly appealing to companies in industries like manufacturing, agriculture, and technology.
