What Is Illinois Sales Tax Exemption and Who Qualifies?
Illinois sales tax exemptions give businesses a smart way to cut costs and run more smoothly. Businesses that qualify can save a lot with these exemptions. And they can still follow Illinois tax rules.
Understanding the Basics of Illinois Sales Tax Exemption
Illinois has four main tax types. Each one covers something different:
Retailers' Occupation Tax (ROT): Charged on the sale of tangible personal property (physical goods).
Service Occupation Tax (SOT): Covers services that involve handing over physical goods.
Service Use Tax (SUT): Paid by people who use services that involve handing over physical goods.
Use Tax: Charged on goods bought for use in Illinois when no tax was paid at the point of sale.
Exemptions lower or remove these taxes for businesses that qualify. For instance, nonprofits can avoid paying ROT on purchases key to their mission. Manufacturers save tax on equipment they need to make their products.

2026 Grocery Tax Repeal: What Illinois Businesses Need to Know
Starting January 1, 2026, Illinois dropped its 1% state grocery tax on qualifying food and drinks. So the state sales tax rate on groceries is now 0%. But local areas may still charge up to 1% in local grocery taxes. That means the real rate on qualifying grocery items varies by location. Businesses that sell food and drinks should check their local rate. Then they should update their point-of-sale systems to match. This keeps them from collecting too much tax from customers.
Who Can Benefit from Sales Tax Exemption in Illinois?
Several industries qualify for Illinois sales tax exemptions. These include nonprofits, manufacturers, farm businesses, and resellers. Each one gains its own benefits:
| Eligible Businesses | Exemptions and Benefits |
|---|---|
| Nonprofits | Exempt from sales tax on purchases supporting charitable, educational, or religious activities. |
| Manufacturers | Machinery, equipment, and replacement parts used primarily in manufacturing or assembling products are exempt. This includes production-line machinery, testing equipment integral to the manufacturing process, and pollution-control facilities used in manufacturing. |
| Agricultural Operations | Farm machinery and parts used in production qualify for exemptions. |
| Resale Businesses | Items purchased for resale are tax-exempt, preventing double taxation. |
| Grocery Retailers | As of 2026, qualifying food and beverage items are exempt from Illinois state sales tax (0% state rate). Local jurisdictions may still levy up to 1%. |
Key benefits also include rolling stock exemptions for transport between states. Some industries also get exemptions on certain software licenses. Businesses that want to use these exemptions can review the papers they need, such as the Illinois Tax-Exempt Certificate. This makes the process smoother.
Common Misconceptions About Illinois Sales Tax Exemption
Businesses often get confused or make errors when they apply for sales tax exemptions. Common issues include:
Eligibility Confusion: Some businesses think they qualify just because of their industry. But what counts is how the item is used.
Misapplied Exemptions: For example, items stored in Illinois for a short time before resale may not meet the rules.
Documentation Mistakes: Missing or incomplete exemption certificates can cost you the exemption. They can also lead to audits or penalties.
Grocery Tax Assumptions: Some retailers think the grocery tax repeal removes all tax on food. In fact, prepared foods, candy, and soft drinks are still taxable at the standard rate. And local grocery taxes of up to 1% may still apply.
For more on exemptions, see the Illinois Department of Revenue's page on Applying for Sales Tax Exemption.
Example Scenario: Misunderstanding Eligibility
A manufacturing company thought all its business purchases were tax-exempt. But tools used for general upkeep were taxable, since they were not tied directly to production. Using the exemption the wrong way led to back taxes and penalties after an audit.
Use resources like Illinois Revenue's Illinois Sales Tax Rules for Businesses. They help businesses stay compliant and avoid needless risk. They also help you make sure every sale is backed by the right tax exemption card.

How to Apply for Illinois Sales Tax Exemption for Your Business
Illinois lets businesses lower their costs through tax exemptions. If you follow a clear set of steps to apply, you can get tax-exempt status and save a lot.
How Do I Get Tax-Exempt Status in Illinois?
To get tax-exempt status in Illinois, businesses must register with the Illinois Department of Revenue (IDOR). They must also get a valid exemption certificate or resale certificate. The process depends on the type of business. But it generally includes these steps:
| Step | Details |
|---|---|
| Register with IDOR | Apply for an Illinois Department of Revenue (IDOR) identification number through the IDOR Registration Portal. |
| Submit Exemption-Specific Applications | Complete applications specific to your industry, such as agricultural, nonprofit, or resale exemptions. |
| Provide Required Documentation | Submit documentation proving eligibility, such as proof of nonprofit status or industry-specific details. |
| Renew Exemptions as Needed | Certain exemptions require periodic renewal to remain valid. |
Documentation for Sales Tax Exemption in Illinois
Accurate paperwork is key for businesses that want tax exemptions. If you don't provide or keep the right records, you could face audits or penalties. You could also lose your exemptions.
| Documentation Type | Purpose |
|---|---|
| Resale Certificate | Used by resale businesses to claim tax exemptions on items intended for resale. |
| Exemption Certificate | Proves eligibility for specific exemptions, such as those for nonprofits or manufacturers. |
| Proof of Industry | Documentation supporting eligibility, such as agricultural certifications or nonprofit status. |
Which Illinois Exemption Form to Use
Illinois uses two forms for exemptions. Which one you use depends on why the purchase is tax-free:
| Form | Covers | When to Use It |
|---|---|---|
| Form CRT-61, Certificate of Resale | Resale | You are buying inventory you will sell. |
| Form ST-587, Equipment Exemption Certificate | Manufacturing, production agriculture, and coal or aggregate mining | You are buying machinery, equipment, or supplies used directly in producing goods. |
Both work the same basic way. The buyer fills in the certificate and gives it to the seller before the sale. The seller keeps it on file to show why it didn't collect tax. Using the wrong form can get the exemption denied. One example is treating a resale certificate as if it also covers equipment purchases. This can happen even when the business qualifies for a different exemption.
