How to calculate your own sales tax in the state of South Dakota.

So, what does this mean for you, if you are looking into how much sales tax you are going to charged dependant on what sort of county you are residing or working out of. You can go ahead and use a sales tax calculator which will give you a section that is exampled below.


-or- Specify Sales Tax Rate
-or- Specify ZIP Code


You do need to know the purchase ZIP code and purchase amount in order to get an accurate figure. For an example we will use the amount of $700 and see what the ranges could be from the highest area to the lowest.

In Sioux Falls, SD with the highest sales tax of 6.5% would mean that your $700 purchase would incur a $45.5 sales tax, taking the total amount to $745.5.

Whereas in Kyle, SD the sales tax is only 4.5% and a $700 purchase would equate to $31.5 tax, taking the total to $731.5.

The sales tax calculator makes it as easy as it can be to find out what sort of sales tax you will be charged by simply adding the amount and the ZIP code. Though there might be some purchases that are exempt from sales taxes or have some special leniency which do need to be taken into consideration.

You will need to collect sales tax if you have any sort of nexus there, and what this means is that if you have assets that are physical or economic then you need to do this.

Physical meaning having a tangible activity or some sort of presence in any of the states of South Dakota, economic nexus is simply passing the states’ economic threshold for total revenue, or the maximum number of transactions that can occur in the period of time within the state.

What is the best way to file sales taxes?

Before you think of doing anything else there are three things that we recommend that you do in order to make this process as easy and smooth as possible.

First of all, find out how much tax you owe (remember the sales tax calculator we mentioned before) so that you know how much you need to pay the state at the end. Second is get onto the South Dakota Department Of Taxation ready to submit them, and third have the money ready so you can make the payment straight away.

There are two main options as well to filing and paying your South Dakota sales tax, these are:

  • Filing online. This is where merchants are required to file all of their sales taxes through the department of taxation in the state of South Dakota, you can also pay your taxes on this platform, so it is one to keep close to you for future reference.
  • Filing by mail. Simply fill out the form UST-1, but this is not the recommended way of filing your taxes due to the possibilities of them getting lost in the post and then it could mean that you are subject to late fees if they are not filed within the allotted time.
