South Dakota Publishes Updated Municipal and Special Jurisdiction Tax Rates Effective July 1

The South Dakota Department of Revenue has published its updated Municipal and Special Jurisdiction Tax Rate Chart, detailing changes to local sales, use, and gross receipts taxes that will take effect on July 1. The semi-annual update provides critical guidance for retailers and other businesses responsible for collecting and remitting taxes across the state's complex web of local jurisdictions.

The revised chart identifies the applicable Municipal Sales Tax, Municipal Gross Receipts Tax (MGRT), and various special jurisdiction tax rates that will be in effect from July 1 through December 31. South Dakota operates on a destination-based sales tax system, meaning the tax rate is determined by the location where the customer receives the product or service. This requires businesses, including remote sellers with economic nexus in the state, to apply the correct combined state and local rate for every transaction.

While these semi-annual updates are a routine part of the compliance calendar, they underscore a significant operational challenge for small and mid-sized businesses. For companies selling into numerous municipalities, tracking these frequent, hyper-local rate adjustments is a substantial administrative burden that carries a high risk of error. The complexity is magnified for e-commerce businesses that must correctly calculate rates for customers across dozens of tax jurisdictions. This landscape became more demanding for many remote sellers after the state eliminated its 200-transaction nexus threshold, leaving a single $100,000 sales threshold that requires compliance with this intricate system. In our experience, many businesses underestimate the resources needed to manage this process accurately. This is a core function where specialized support is not a luxury but a necessity for risk management.

The updated guidance from the Department of Revenue covers a wide array of local taxes beyond general sales tax. It includes specific rates for tribal jurisdictions, such as the 2% tax in Eagle Butte and Isabel within the Cheyenne River Special Jurisdiction and the 1.5% rate in Morristown within the Standing Rock Special Jurisdiction. The chart also details special-purpose taxes that apply statewide or in certain areas, including the 4% telecommunications tax, a 1.5% tourism tax, and a 1% lodging tax specific to Sioux Falls. The purpose of the detailed chart is to provide a single source of truth for businesses to configure their point-of-sale systems, e-commerce platforms, and accounting software to ensure proper tax collection.

These periodic adjustments are governed by South Dakota Codified Law 10-52-9, which authorizes municipalities to implement new tax rates or change existing ones on a semi-annual basis, effective either January 1 or July 1 each year. This predictable schedule provides a framework for businesses, but it also creates an ongoing need for vigilance to stay current with the latest changes. The Department of Revenue supports businesses by publishing Municipal Tax Information Bulletins, which contain a comprehensive list of all municipal and tribal tax rates.

While the current July 1 update contains numerous routine rate adjustments, the Department of Revenue has also announced more significant changes scheduled for the coming years, illustrating the dynamic nature of the state's tax environment. For example, beginning July 1, 2025, the communities of Newell and Wagner will implement a new 1% municipal gross receipts tax specifically targeting lodging accommodations, eating establishments, alcohol sales, and admissions. Further out, effective July 1, 2026, the town of South Shore will double its general sales and use tax rate from 1% to 2%.

For businesses located outside of South Dakota, understanding these local rates is not optional. Since the Supreme Court's 2018 decision in South Dakota v. Wayfair, Inc., remote sellers meeting the state's economic nexus threshold of $100,000 in gross sales in the previous or current calendar year are required to collect and remit sales tax. As a member of the Streamlined Sales and Use Tax Agreement, South Dakota's destination-based sourcing rules mean these remote sellers are responsible for applying the specific local rate at the customer's delivery address, making the Department of Revenue's updated charts an essential compliance tool.

Businesses operating in South Dakota should ensure their financial systems are updated to reflect the new rates by the July 1 effective date to avoid under- or over-collection of taxes. Companies should also anticipate the next round of potential changes, which will be announced ahead of the subsequent January 1 effective date, and incorporate monitoring of these state announcements into their regular compliance procedures.
