Understanding Union County Tax Rates

In Union County, South Dakota, the total sales tax rate you pay is a combination of the state base rate and any additional municipal or local sales taxes. South Dakota currently maintains a state sales tax rate of 4.2%. However, cities within Union County, such as North Sioux City, Elk Point, or Beresford, may impose additional local sales taxes to fund local infrastructure and public services. It is important to note that South Dakota does not impose a state personal income tax or a state corporate income tax, which can significantly influence your overall financial planning when compared to other states.

What's Taxable in Union County?

Most tangible personal property and certain services are subject to sales tax in South Dakota. While the base rules are determined at the state level, residents should be aware of specific categories regarding taxability:

• Taxable Goods: Most retail goods, electronics, furniture, and non-essential items are fully taxable.
• Groceries: South Dakota does not impose a state sales tax on most grocery food items, though local municipal taxes may still apply depending on the specific city ordinance.
• Prescription Drugs: Prescription medicines and medical devices are generally exempt from state sales tax.
• Services: Certain services, including construction labor, professional services, and utility services, may be subject to excise or sales taxes.

Recent Rate Changes

Tax rates in Union County are subject to change due to local ballot measures, municipal annexations, or state-level legislative adjustments. When a city within the county decides to implement a new local option tax or adjust an existing one, these changes are typically scheduled to take effect at the start of a calendar quarter. Because local ordinances can fluctuate, it is essential for both residents and business owners to verify the most current tax jurisdiction codes and rates. Always cross-reference your calculations with the official South Dakota Department of Revenue website or their tax rate database to ensure accuracy for your specific location.
