Note that the 4.2% current state rate is only temporary starting in 2023. It’s slated to return to 4.5% on July 1, 2027. Alcohol, eating establishments, lodging, and admissions can also carry an extra 1% Municipal Gross Receipts Tax on top of the standard combined rate. Sales tax sourcing in South Dakota is destination based. This means you charge sales tax at the rate at your customer’s delivery address. If they are taking delivery in Sturgis, you charge them the sales tax rate at that location. Register, file and pay through South Dakota’s sales tax port, EPath. ### South Dakota Total Sales Tax Rates **City** **State Rate** **Municipal Rate** **Total Combined Rate** Sioux Falls 4.2% 2% 6.2% Rapid City 4.2% 2% 6.2% Aberdeen 4.2% 2% 6.2% Brookings 4.2% 2% 6.2% Watertown 4.2% 2% 6.2% Unincorporated Area 4.2% N/A 4.2% It’s important to note that two 2026 laws can push rates above 6.2%.

Both took effect July 1, 2026. Meade County was the first county to adopt the county tax.

The default in South Dakota is that a sale is taxable. ### SaaS and Digital Products [SaaS](https://www.getsphere.com/blog/are-subscriptions-taxable), software, streaming, apps, and other digital goods are taxable in South Dakota. The state taxes products transferred electronically as a sale of tangible personal property, and it taxes most services by default. Either way, a subscription sold to a South Dakota customer is taxable. Unlike in some other states, taxability does not depend on temporary or permanent access. A three-day rental of a digital product is taxed the same as a permanent download. Also unlike other states, computer support services and consulting services are also listed by the Department of Revenue as taxable services. Selling SaaS or digital goods into South Dakota? [Sphere](https://www.getsphere.com/) classifies your South Dakota digital transactions and applies the correct combined rate automatically. ### Tangible Personal Property (TPP) Physical goods sold at retail are taxable at the combined state and municipal rate unless a specific exemption applies by law or the buyer provides a valid [exemption certificate](/blog/exemption-certificate-management). South Dakota's base is broad, so fewer exemptions exist than you may expect from other states. Unlike in most other states, groceries in South Dakota are taxable at the full combined rate. However, prescription drugs are exempt, and insulin is exempt whether or not it is prescribed. Though over-the-counter drugs and medical devices used on more than one patient are taxable. Delivery (shipping) charges are also taxable in South Dakota. ### Services South Dakota taxes services by default, then carves out specific exemptions. Most states do the reverse, so a service that is untaxed in your home state may be taxable here. Exempt services include: - health services - educational services - social services - financial services - trucking - construction services (these fall under contractor's excise tax) To determine whether you should apply sales tax to your services in South Dakota, check with the state to see if it has been exempted by law. If it hasn’t, then it’s taxable. ## Monitoring: When South Dakota Sales Tax Applies to You You’re required to collect South Dakota sales tax once you have [sales tax nexus](/blog/nexus-tax-software) in the state. ### Economic Nexus Threshold South Dakota's economic nexus threshold is $100,000 in gross sales into South Dakota in the previous or current calendar year. The threshold has applied since November 1, 2018, following the precedent-setting _South Dakota v. Wayfair_ Supreme Court case. Once you cross this threshold, you are liable to collect sales tax in the state. You must register by the first day of the month that begins at least 30 days after you meet the threshold. [Sphere](https://www.getsphere.com/) monitors your South Dakota gross sales and alerts you before you cross $100,000. ### Physical Nexus Any physical presence in South Dakota creates nexus regardless of revenue. That includes an office, employees, contractors or representatives, and inventory stored in the state. The $100,000 threshold does not apply to a business with physical presence. If you have physical presence, you register from your first taxable sale. ### Marketplace Facilitators Starting March 1, 2019, marketplace providers collect and remit South Dakota sales tax on behalf of their third-party sellers. A marketplace must register if it is a remote seller itself, if it facilitates sales for at least one seller that meets the remote seller criteria, or if the combined sales of two or more of its sellers meet the criteria. If a marketplace collects sales tax on your sales, you are not responsible for collecting on those transactions. You should still track them, because marketplace sales count toward your own gross sales into the state and determine whether you have economic nexus. ## Registration: How to Register for South Dakota Sales Tax Register for a South Dakota sales tax license through the Department of Revenue's online Tax License Application before your first taxable sale. ### How to Register Go to the [South Dakota Tax License Application](https://dor.sd.gov/online-services/tax-license-application/) and apply for a Sales & Use Tax license. You will need entity and ownership details plus personal information for owners, partners, or officers. Processing isn’t instant. It will take 1-5 business days for approval and then your permit will arrive by mail 7-10 business days after that. ### Registration Fees South Dakota does not charge a fee to register for a sales tax license. [Sphere](https://www.getsphere.com/) manages the full South Dakota registration process on your behalf, including the supporting documentation. ## Calculation: South Dakota Sales Tax Rates ### State and Local Rate The state rate is 4.2%. Municipal rates run from 1% to 2%, so combined rates land between 4.2% and 6.2% in most of the state. More than 200 municipalities impose a local tax. Additional 2026 tax laws mean some counties can have a sales tax rate up to 7.2%. Municipal rate changes take effect only on January 1 or July 1. County rates adopted under Senate Bill 96 follow the same January 1 and July 1 schedule. Some areas covered by tribal tax collection agreements are treated as special jurisdictions with their own codes and rates. Always verify current rates before collecting. ### Municipal Gross Receipts Tax (MGRT) The Municipal Gross Receipts Tax is an additional 1% tax that participating cities impose on alcoholic beverages, eating establishments, lodging accommodations, and admissions to amusement, athletic, and cultural events. MGRT stacks on top of state and municipal sales tax. In those categories, the total can reach 7.2% in a city charging the full 2% municipal rate. ### What the Rate Applies To The combined rate applies to taxable tangible personal property, products transferred electronically like SaaS and digital products, and taxable services. Prescription drugs and insulin are exempt from sales tax. ## Filing: How and When to File South Dakota Sales Tax Returns File South Dakota sales and use tax returns electronically through EPath. A return is due every period, even when you had no sales. ### Filing via EPath File your South Dakota sales tax return electronically via [EPath](https://sd.gov/taxes). Note that a “zero return” is due even if you made no sales for the taxable period. ### Filing Deadlines All electronic returns are due the 20th of the month following the reporting period, while electronic payments are due the 25th. Paper returns and payments are both due on the 20th. If a due date falls on a weekend or legal holiday, the next business day applies. ### Filing Frequency Thresholds The Department of Revenue assigns your filing frequency based on sales volume. Assignments include monthly, quarterly, semi-annual, annual, and seasonal. South Dakota does not publish dollar thresholds for each tier, so confirm your filing frequency with the Department of Revenue when your license is issued. ### Late Filing Penalties South Dakota assesses a 10% penalty on your tax liability if a return is not received within 30 days following the month it is due. The minimum penalty is $10, and it applies even when no tax is owed. Interest runs at 1% per month on unpaid tax, with a $5 minimum for the first month. Continued failure to file can escalate. The Department can issue an estimated assessment, file a tax lien, or even revoke your license. ## Remittance: How to Pay South Dakota Sales Tax ### Remittance via EPath You can pay South Dakota sales tax through EPath by ACH debit, ACH credit, or card. Visa, MasterCard, and Discover are accepted with a nonrefundable convenience fee. You can also arrange for ACH debit through your own bank. ### Remittance for Foreign Businesses Businesses without a US bank account cannot use the standard ACH debit method. If your entity is based outside the US, [Sphere's](https://www.getsphere.com/) embedded remittance platform submits South Dakota payments on your behalf, so you do not need to open a US account to stay compliant. ## How Sphere Helps With South Dakota Sales Tax Compliance ![South Dakota Sales Tax Compliance](https://cdn.sanity.io/images/jldqsjg6/production/0491cfc907aa8ee83a6237c3e1bd22ce62ccc3b5-3960x2100.png?q=80&fit=max&auto=format&w=3840) Sphere automates South Dakota sales tax compliance end to end: - Monitors your gross sales into South Dakota and flags the $100,000 economic nexus threshold before you cross it. - Handles registration with the South Dakota Department of Revenue. - Classifies digital products, physical goods, and services, then applies the correct combined rate by delivery address. - Files returns in EPath on schedule, including zero returns. - Remits payment, including for businesses without a US bank account. - Manages exemption and resale certificates so exempt sales hold up in an audit.
