South Dakota sales tax applies to almost everything you buy in the state. The current state rate sits at 4.20%, well below the national average. However, South Dakota taxes groceries, clothing, and over-the-counter medicine at the full rate. Very few consumer exemptions exist here. Understanding what you’ll actually pay at the register helps you budget better and shop smarter. This guide covers every South Dakota sales tax detail that matters to your wallet in 2026.
South Dakota Sales Tax Rate: The Basics
The South Dakota sales tax rate is 4.20% at the state level. This temporary reduction from 4.50% took effect on July 1, 2023. It remains in place through June 30, 2027. Most cities add a 2.00% local tax on top. As a result, shoppers in major metro areas typically pay 6.20% at the register.
| Tax Component | Rate |
|---|---|
| State Sales Tax | 4.20% |
| Average Local Tax | 1.91% |
| Average Combined Rate | 6.11% |
| National Average Combined | 8.68% |
South Dakota’s average combined rate of 6.11% falls well below the national average of 8.68%. Specifically, you save roughly $2.57 per $100 compared to the typical American shopper. For big purchases like appliances or electronics, that difference adds up quickly. Check our month-by-month buying calendar to time those major purchases for even bigger savings.
In addition, a rate increase is scheduled for July 1, 2027. The state rate will return to 4.50% on that date. New county and city tax options authorized in 2026 could push local rates higher in some areas as well.
What South Dakota Does and Does Not Tax
South Dakota taxes nearly everything shoppers buy. The state has no income tax. As a result, it relies heavily on sales tax revenue. This means very few items are exempt at the checkout counter.
Groceries are fully taxed at the standard rate. South Dakota is one of the only states that charges full tax on unprepared food. Clothing and footwear are also taxable with no exceptions. However, prescription drugs are exempt from South Dakota sales tax. Insulin is also exempt, even without a prescription. Purchases made with SNAP or WIC benefits are tax-free under federal law.
| Category | Taxed? | Rate |
|---|---|---|
| Groceries (Unprepared Food) | Yes | Full rate |
| Clothing & Footwear | Yes | Full rate |
| Over-the-Counter Medicine | Yes | Full rate |
| Restaurant Meals & Prepared Food | Yes | Full rate |
| Digital Products & Downloads | Yes | Full rate |
| Prescription Drugs | No | Exempt |
| Insulin (With or Without Rx) | No | Exempt |
| SNAP/WIC Purchases | No | Exempt |
For example, a $150 weekly grocery trip in Sioux Falls costs an extra $9.30 in tax. That adds up to over $480 per year for a family spending $600 monthly on food. Our coupon stacking guide can help offset those costs at the register.
South Dakota Sales Tax by City and County
Most major cities in South Dakota charge the maximum 2.00% municipal sales tax. This gives shoppers in virtually every metro area a combined rate of 6.20%. However, some smaller towns and special jurisdictions charge significantly more.
| City | State Rate | Local Rate | Combined Rate |
|---|---|---|---|
| Sioux Falls | 4.20% | 2.00% | 6.20% |
| Rapid City | 4.20% | 2.00% | 6.20% |
| Aberdeen | 4.20% | 2.00% | 6.20% |
| Brookings | 4.20% | 2.00% | 6.20% |
| Watertown | 4.20% | 2.00% | 6.20% |
| Pierre | 4.20% | 2.00% | 6.20% |
| Mitchell | 4.20% | 2.00% | 6.20% |
| Yankton | 4.20% | 2.00% | 6.20% |
Specifically, the towns of Martin and Parmelee have combined rates reaching 10.40%. These higher rates come from special jurisdiction taxes. In addition, 2026 legislation now allows counties to impose an optional 0.50% tax. Cities can also add a temporary 1.00% capital project tax. South Dakota sales tax rates could vary more by location in the coming years as communities adopt these new options.
South Dakota Sales Tax Holidays
South Dakota does not offer any sales tax holidays. There are no back-to-school tax-free weekends. There are no disaster preparedness exemption periods. No temporary tax breaks exist for clothing, electronics, or school supplies.
However, several nearby states do offer tax-free shopping events. Montana has no sales tax at all, year-round. Iowa holds an annual back-to-school holiday each August. If you live near a state border, a shopping trip during one of these events can save you real money on bigger purchases. Browse our shopping guides for more state-by-state strategies.
Online Shopping and South Dakota Sales Tax
South Dakota changed online shopping forever. The 2018 Supreme Court case South Dakota v. Wayfair gave states the power to require online retailers to collect sales tax. As a result, you now pay South Dakota sales tax on virtually all online purchases shipped to the state.
Amazon, Walmart.com, eBay, Etsy, and other major marketplaces all collect the tax automatically. The rate is based on your shipping address, not the seller’s location. South Dakota uses destination-based sourcing. This means your delivery address determines the exact rate you pay.

Smart Shopping Tips for South Dakota
1. Use cashback apps on every purchase. Since South Dakota sales tax hits nearly everything you buy, cashback rebates help recover some of that cost. Even 2–3% back on groceries and clothing adds up over a full year of shopping.
2. Ask about prescription alternatives. Prescription drugs are exempt from sales tax. If your doctor can write a prescription for a medication you currently buy over the counter, you’ll avoid tax on every refill.
3. Shop in Montana for big-ticket items. Montana charges zero sales tax on anything. If you live in western South Dakota near the border, driving to Montana for a large purchase can save you real money. A $1,000 appliance saves you $62 in tax compared to buying it in Sioux Falls.
4. Make major purchases before July 2027. The state rate jumps from 4.20% to 4.50% on July 1, 2027. Specifically, that extra 0.30% adds $3 per $1,000 spent. Plan ahead for furniture, electronics, and other large buys.
5. Check your delivery address for online orders. South Dakota uses destination-based taxation. Shipping to an address outside city limits may lower your total rate. However, always verify the exact rate for your specific location before ordering.
