In today's fast moving world, keeping informed on the public policies that impact your personal or work life is a daunting task. Fortunately, technology can aid in that effort and that is the ultimate purpose of Key Policy Data.
We accomplish this goal with the help of the innovative Qlikview data visualization and discovery program. Qlikview allows us to post huge amounts of data without sacrificing usability. For instance, our state and county tax burden app can quickly show you how your state's tax burden ranks and how it has changed over time with just a few clicks of a button.
We hope that you find the information on Key Policy Data useful and we simply request that you share this website with your friends and family. Additionally, be sure to sign up for our mailing list to make sure you don't miss any of our analysis on the important public policy issues impacting your state.
In Fiscal Year (FY) 2015, South Dakota collected $3.3 billion in state and local taxes. While this is an impressive sum of money, it tells us little about whether or not the average South Dakota taxpayers can afford this level of taxation.
As shown in Chart 1, South Dakota’s state and local tax burden (tax collections divided by private sector personal income) was the fourth lowest in the nation for FY 2015 at 11.1 percent—or -23 percent below the national average of 14.4 percent.
As shown in Chart 2, South Dakota’s tax burden has decreased over time by -8 percent to 11.1 percent in FY 2015 from 12 percent in FY 1950. Only Florida and Alaska (since statehood in 1959) have accomplished this amazing feat.
As shown in Chart 3, South Dakota's 11.1 percent tax burden is greater than these combined industries: farming (7.2 percent), accommodations and food services (3.1 percent), and utilities (0.8 percent).
South Dakota’s low state and local tax burden is driven by the fact that it does not have a state individual income tax or state corporate income tax. Additionally, relative to the national average, the state and local property tax burden is -11 percent lower (3.9 percent vs. 4.4 percent) and all other taxes are -1 percent lower (2.6 percent vs. 2.7 percent). However, the sales tax is 34 percent higher than the national average (4.6 percent vs. 3.4 percent) and is the 11th highest in the country which offsets lower taxes elsewhere.
The sales tax burden is a concern even beyond its high burden. According to the Tax Foundation, as of January 1, 2017, South Dakota’s combined state and local sales tax rate (South Dakota allows for local option sales taxes) is only 6.39 percent—the 31st highest in the country. As such, in order to raise such a high amount of revenue, the relatively low sales tax rate has to be levied on a very broad-based number of goods and services which leads to a concern of tax pyramiding. Sales tax pyramiding creates all kinds of very bad economic distortions most often associated with a gross receipts tax (pdf).
Nevertheless, even a bad sales tax does not offset the economic benefits of having the country’s 4th lowest tax burden. South Dakota taxpayers need to make sure their policymakers understand that point first and foremost.
Of course, the tax burdens for local government can vary just as much as they do among the 50 states. As such, we have also calculated the local government tax burden for every county in South Dakota—this includes every taxing jurisdiction within the geographic county borders whether it is a city, a special district, or county government itself.
