On January 1, 2021, Illinois changed their sales tax filing requirements for remote sellers without a physical presence in the state. By the way, having inventory in an FBA warehouse does not count as having a physical presence in Illinois. 

The reason why Illinois made these changes was to level the playing field for remote vs. in-state sellers. In-state sellers have already been collecting both the Use tax and the local rates. But remote sellers didn’t have to worry about the local tax responsibility. That is, until now. 

What Rates Should You Be Collecting as a Remote Seller vs. An In-state Seller? 

Previously, remote sellers simply collected 6.25% sales tax and filed a Use Tax return. That is now changing as remote sellers are now required to pay the local tax rates, as well. If you fit the criteria, you must switch over to collecting Retailers’ Occupational Tax. This is a destination-based tax and is collected at both the state & local levels. 

What Do You Need to Do to Comply with the New Illinois Sales Tax Law? 

In order to comply with this law, you’ll need to do two things: 

  1. Switch your account from a Use Tax acct to a Retailer’s Occupational Tax acct. 
  1. Fill out an ST-1 form AND an ST-2 form when you file. 

Why Are You Getting All These Registration Certificates All the Time? 

So, you may be wondering why you keep getting identical registration certificates in the mail all the time. Now’s a good time to break out our food truck analogy. 

Imagine that you own a traveling food truck. Some days you park in a neighborhood parking lot to sell to the lunch crowd there. 

 

Other days you go to a carnival in another town to sell your delicious food to the partygoers.

At each location, you’ve created a physical presence just by being there. You charge the local sales tax rate, as well as the state rate.  

In Illinois’s eyes, they view remote sellers like this “food truck” that is traveling all over the state, selling its wares. Where it stops is the customer’s location, and it’s required to collect sales tax at that location’s rate. 

So, what’s with all the registration certificates? 

A brick-and-mortar store, by its definition, has a physical presence where it is located. By law, it is required to display its sales tax license.  

With this food truck analogy, each stop on the food truck’s route / new ecommerce customer is a new location. Thus, the state’s system automatically sends out a new sales tax license for it. 

So, the certificates may LOOK the same because the same location code is used, but they are all for different places. Don’t worry about keeping track of the differences, though. Thankfully their system is doing that. 

Since each location generates a new license, and Illinois renews their licenses every year, it’s safe to assume you’ll just keep receiving new ones in the mail all the time. Just store them and don’t worry about it. 

How to Fill Out the Illinois Sales Tax Forms ST-1 & ST-2

Before the changes on January 1, 2021, everything for remote sellers was reported on Line 6a. You’d put your sales in, and it would automatically multiply them by 6.25% and add it to Line 6b.

Line 6a would match Line 1, and there really wasn’t much more information you had to add to the form. Then it would calculate net tax due in Step 6, and you’d be set. Remit it and you were done. 

 

Unfortunately, that is no longer the case. Now you have to fill out Form ST-2, too.

You now need to report every location (customer address), how much the transaction was, along with the specific rate associated with it. It’ll autofill the total amount of sales tax owed. And yes, this is customer by customer.  The info will feed back into the corresponding line numbers on Form ST-1. It’ll fill out this part now. 

By the way, it’s for this reason that we recommend using a sales tax tool for Illinois. It’s so you’re not having to do all this by hand.
