What products and services are taxable in Illinois?
Physical products
There are a few exceptions, but almost all physical products are taxable when sold at retail in Illinois. Common examples include:
- General merchandise like furniture, appliances, and clothing
- Titled or registered items like vehicles
- Qualifying food, prescriptions, and medical appliances
Certain manufacturing equipment is tax-exempt.
Labor, in most cases, isn’t taxable in Illinois. For instance, let’s say you broke the screen of your cell phone and take it to a cell phone repair shop to have it fixed. Sales tax would be added to the selling price of the new screen and any additional parts to fix the phone. The labor to replace the screen isn’t taxable. However, a business that makes furniture will indirectly have a sales tax on labor. In this instance, let’s say this business is building a dining room table for a customer. Through labor, the pieces of wood are shaped, sanded, and painted to build this piece of furniture. While the labor isn’t directly taxable, sales tax is charged to the final selling price of the table.
Digital Products
Digital products, with the exception of canned software (pre-made software), aren’t taxable.
Services
Most services aren’t taxable in Illinois, however, there are a few exceptions.
- Short-term lodging
- Automobile rentals
- Coin-operated amusement devices
A list of common sales tax exemptions is found on the Illinois Department of Revenue’s website.

Sales tax reporting
How is sales tax collected?
When a business sells a taxable product or service, the business charges the appropriate sales tax rate to the customer. This tax is collected by the company and then sends it to the Illinois Department of Revenue.
There are two ways to submit sales tax to the Illinois Department of Revenue. One is by filing online through MyTaxIllinois, and the other is by mailing form ST-1. The ST-1 is only available to businesses with less than $20,000 in annual sales tax liability.
How much is the Illinois sales tax?
The sales tax rate that is charged varies depending on the address of the business if the purchase is made or shipped from a business located in the state. If the seller is based out of the state, the sales tax rate is based on the buyer’s address.
In addition to the statewide tax, there are additional sales taxes that may be added by cities and municipalities. The Illinois Department of Revenue has a Sales Tax Rate Finder to determine how much sales tax to charge.
When are Illinois sales tax returns due?
The Department of Revenue will determine a filing frequency based on the expected volume of annual sales, which will be monthly, quarterly, or annually. Generally, a business selling over $30,000 annually in taxable sales will file monthly. The frequency is re-evaluated annually.
The due date for filings is the 20th day of the month following the reporting period unless the 20th falls on a weekend or federal holiday, which would move to the next business day.
Even if the business had no sales during the reporting period, a filing is still required indicating no sales.
Common Sales Tax Permit Questions
How much is a sales tax permit in Illinois?
There is no cost for a sales tax permit in Illinois.
How long does it take to get an Illinois sales tax permit?

How do I get a wholesale license in Illinois?
A wholesale license allows a business to purchase items to resell without paying state sales tax. The tax liability is passed from the distributor to the retailer, who will then charge sales tax to the end-user of the item.
Wholesalers and distributors will require a sales tax number and a completed Illinois Certificate of Resale (also referred to as a resale certificate, resale license, or sales tax exemption certificate) to document the items being purchased are for resale.
Is a business license the same thing as a sales tax license?
In addition to registering for a sales tax permit, there may be other business licenses needed before starting a business in Illinois.
Do you have to renew your Illinois sales tax permit?
The sales tax permit is a one-time registration, and no renewals are needed. Be mindful that if any information about the business changes, such as the mailing address, additional locations, or change in ownership, those changes need to be updated with the Department of Revenue.
