In recent years, several laws have given states more power to collect these internet sales taxes. This article will discuss recent laws relating to internet sales, what the current laws mean for online sellers, and how to get help when you need it. 

South Dakota v. Wayfair Inc. 

In June 2018, the Supreme Court published a decision in the case of South Dakota v. Wayfair, Inc. (Wayfair) that changed the way states regulate internet sales taxes. South Dakota filed a suit because, as there was no required sales tax for out-of-state companies, the state lost between $48 and $58 million each year because they couldn’t collect internet sales taxes. The ruling upheld a South Dakota law that required out-of-state sellers to collect and pay sales tax “as if the seller had a physical presence in the state.” This decision gave other states a way to enact similar laws requiring online sellers to collect and pay sales taxes on internet sales, even if they did not reside in that state.   The 2018 decision overturned several previous Supreme Court decisions, most recently Quill Corp. v. North Dakota. In that case, the state of North Dakota filed an action against the Quill Corporation—an out-of-state mail-order office equipment retailer—to charge North Dakota use tax on the merchandise being used within the state. The court ruled in favor of the Quill company, deeming the state’s use tax to be unconstitutional because it interfered with interstate commerce.

What the Law Means for You

At issue in these cases is the concept of connection between a taxing entity such as a state and the business being taxed, called a tax nexus. Before the Internet, that connection was physical, because all businesses had a physical location (a building, warehouse, retail store, etc.).  In the case of Quill, the concept of physical presence was upheld, but in Wayfair, the Court took away the physical presence requirement for online transactions.  In the years after the Quill decision, many states enacted new laws to try to get around the physical nexus rule. In fact, at the time of the Wayfair decision, 31 states had some version of an internet sales tax law. Since this decision, more and more states are updating or enacting internet sales tax laws.  

Complying With Internet Sales Tax Laws

As an online seller, you must figure out a way to charge customers the correct amount of sales tax, add the amount to your accounting system, and report and pay the amounts to your state taxing agency. 

Familiarize Yourself with Internet Sales Tax Laws 

The first step is to understand how the state laws work and to see if your small business must pay these taxes. Sales taxes are complex, with many taxing entities. Forty-five states and the District of Columbia collect sales taxes, while local sales taxes are collected in 38 states. Five states—Alaska, Delaware, New Hampshire, Montana, and Oregon—have no state sales tax but Alaska allows localities to charge local sales taxes.

Sales Tax Base and Rates 

To charge sales tax—internet or physical—to a customer, you must know the sales tax base and rates.  The sales tax base is the products or services that are taxable in your state. Some states exempt necessities like groceries from sales tax, and other states exempt clothing or tax it at a lower rate. Most other products are taxable, and states may also tax certain services. 

The Sales Tax Process

To collect, report, and pay sales taxes for internet transactions appropriately, you need to do the following steps: As mentioned, each state has its own requirements for the process. Florida, for example, requires sellers to report gross sales, exempt sales, the taxable amount, and the tax due. The report is due on the first of each month for the previous month, along with the total tax due for the month.

State Sales Tax Registration

When it comes to registering in specific states, the process can be complicated. You have no way of knowing where your internet sales will come from or if you will go over the threshold in any state, so you may need to register in every state.  You can simplify the registration process by registering with the Streamlined Sales Tax Governing Board, Inc. (SSTI). This organization administers an agreement between 24 states for uniformity of sales tax systems. However, among the states that don’t participate are six of the largest: California, Florida, Texas, New York, Illinois, and Pennsylvania. Through the SSTI, you can use the free registration process (SSTRS) to set up an account and report and pay sales taxes directly to each participating state. You will also need to register with SSTRS if you want to contract with one of their Certified Service Providers (CSPs). If you want to register with a state that isn’t an SST member, you will have to register with that state separately. 

Consider Using an Online Sales Tax Service

Your business can use an online service to register with states and manage your sales tax collections, reports, and payments too. Some of these services are also CSPs for Streamlined Sales Tax, including Avalara, TaxCloud, Sovos, and Accurate Tax.
