When you’re thinking about opening a business in South Dakota, or you’re contemplating expanding your service area into the state, it’s important to learn about the sales tax laws there and how they will impact you. While there are many similarities between the sales tax laws in South Dakota when compared with those in other states, there are also some details that are specific to South Dakota that you’ll need to be aware of to ensure you stay compliant at all times.

South Dakota Sales Tax Rates

Like most states, South Dakota has a blanket state sales tax rate of 4.5% that applies everywhere. This is supplemented in most parts of the state by local taxes that bring the total effective rate up to between 5.5% and 6.5%. A few local jurisdictions in the state like Pine Ridge and Blackhawk don’t add their own tax, which means customers in that area will only pay the 4.5% state rate.

South Dakota is a destination-based state when it comes to sales tax, which means that the applicable rate will be that at the place the customer takes possession of the product purchased or the location of services rendered. If you have a physical store, that means your customers will all pay the rate that is in effect at the store’s location. If you’re shipping products to your customers, however, the applicable rate will be that of the delivery address.

Nexus Regulations in South Dakota

South Dakota can only compel retailers and service providers to collect and remit sales tax on purchases by customers within the state if the seller has a significant presence, or nexus, there. Of course, if you operate a physical store or office in the state, you will be considered to have nexus, and other qualifying conditions include:

  • Storing goods in a warehouse in the state
  • Having an employee or other representative operating in the state regularly
  • Making deliveries in vehicles owned by the seller
  • Maintaining contracts for realty improvement in the state

There are currently no Amazon fulfillment centers in South Dakota, so if you use fulfillment by Amazon, you won’t have to worry about a nexus being triggered simply +by your goods being stored in one of their warehouses. South Dakota did recently pass an economic nexus law, however, and so that is something to be aware of if you are a remote seller making sales to South Dakota customers.

South Dakota’s economic nexus law requires any out-of-state business to collect and remit sales tax to the state if, in the previous calendar year:

  • They have more than $100,000 in sales of tangible personal property, electronically-delivered products, or services rendered in South Dakota; or
  • They sold tangible personal property, electronically-delivered products, or rendered services in 200 or more separate transactions.

At first this law was considered unconstitutional, and several retailers sued South Dakota as a result. The case was finally settled in June, 2018 by the U.S. Supreme Court, in a decision known as South Dakota v. Wayfair, Inc. In this case, the Supreme Court overturned the 1992 decision that prevented states from being able to compel retailers with no physical presences to collect sales tax on purchases made within a given state. So it’s important to know the economic nexus law in South Dakota and to understand if your sales are high enough to meet the threshold.

What’s Taxable?

Most sales of tangible personal property, including groceries, are taxable in South Dakota, as are the vast majority of services. Some notable exemptions include:

  • Food stamp and WIC purchases
  • Water
  • Warranty parts and services
  • Raw materials
  • Repair services
  • Lottery sales
  • Advertising services
  • Livestock
  • Farm machinery
  • Medical devices
  • Health services
  • Prescription medicine
  • Raw materials

All types of digital products and software are taxed, including custom software, and that is true regardless of whether the product is delivered electronically or on physical media. Shipping and handling charges are also taxable as long as the product being shipped is taxable. Certain organizations or individuals may qualify for exemption certificates in order to purchase tax-free items that would normally be taxed, but they will need to obtain an exemption certificate from the state ahead of time and present it at the time of purchase.

Registration and Filing

If you are obligated to collect and remit sales tax in South Dakota, you will have to register with the state. This can be done online through the state website or in person. Because South Dakota is also a full member of the Streamlined Sales and Use Tax Agreement (SSUTA), you can also register for a sales tax license through the SSUTA website. However, registering in that way requires you to register with all member states at once, and that may or may not make sense for you depending on your situation.

Regardless of how you register, there is no fee, and you may begin making taxable sales in South Dakota as soon as you receive your license in the mail. When you obtain your license, you will also be assigned a filing frequency by the state based on your expected sales, and this can be monthly, bi-monthly, semi-annual, annual, or seasonal. Returns can be filed either online or through the mail.

Due Dates and Penalties

South Dakota recently updated its due dates for sales tax returns and payments. As of July 2017, returns are due on the 20th of the month following the close of the period in question for those filing both electronically and non-electronically. Payments made electronically need to be received by the 25th of that same month, while payments for returns filed by mail must accompany those returns. If any of these due dates falls on a weekend or holiday, the returns and payments will be considered timely if received by the next business day.

Late filing of your South Dakota sales tax returns or late payment of the tax due will result in penalties imposed by the state. The penalty for a failure to pay within 30 days of the due date is 10% of the tax due for every month you are delinquent, with a minimum charge of $10. Interest also accrues at a rate of 1.25% per month, with a minimum of $5 for the first month.
