Illinois SaaS Sales Tax: Software Type and License Structure Determine Taxability
Illinois software taxability depends on the nature of the transaction.
Key categories include:
- canned or prewritten software;
- software licenses;
- custom computer software.
Retail sales of canned software are generally taxable. Certain software licenses may be non-taxable if specific conditions are met. Qualifying custom computer software is not taxable.
Canned Software Is Generally Taxable
Illinois treats retail sales of canned software, also known as prewritten software, as taxable when the software is intended for general or repeated use.
The rule applies regardless of the form in which the software is transmitted, including electronic delivery.
Example:
Canned software download USD 500
If the software is prewritten and sold for general or repeated use, the transaction is taxable.
Electronic Delivery Does Not Automatically Make Software Non-Taxable
Illinois specifically states that canned software remains taxable regardless of transmission method.
Example:
Downloaded software license USD 1,000
If the software is canned software, electronic delivery does not remove it from Illinois taxability.
Software Licenses May Be Non-Taxable if Conditions Are Met
A license of computer software is not taxable if specific conditions are met under 86 Ill. Adm. Code 130.1935(a)(1).
Software businesses should review:
- license terms;
- customer usage rights;
- whether software copies are transferred;
- billing structure;
- whether the license satisfies Illinois requirements.
The label “license” alone does not determine tax treatment. The transaction must meet the required conditions.
Custom Computer Software Is Not Taxable if Criteria Are Met
Sales of custom computer software are not taxable if the relevant criteria are satisfied under 86 Ill. Adm. Code 130.1935(c)(1).
Example:
Custom software development USD 20,000
If software is developed for a specific customer and is not canned software intended for general or repeated use, it may qualify as custom computer software.
Businesses should maintain:
- development agreements;
- statements of work;
- invoices;
- project documentation.
SaaS Requires Transaction Analysis
The Illinois source specifically addresses canned software, software licenses, and custom software. For SaaS businesses, the key issue is how the SaaS arrangement is structured.
Example:
Monthly SaaS subscription USD 300/month
A SaaS transaction should be reviewed to determine whether it is treated as:
- taxable canned software;
- a qualifying non-taxable software license;
- custom software;
- or another type of service arrangement.
Common Illinois SaaS Compliance Issues
Assuming downloaded software is exempt
Illinois taxes canned software regardless of whether it is delivered electronically.
Relying only on invoice labels
Labels such as “license fee,” “subscription fee,” or “service fee” do not control tax treatment.
Confusing canned software with custom software
Standard software sold to multiple customers is different from software custom-developed for one customer.
Failing to retain license documentation
Businesses claiming non-taxable license treatment should maintain documentation showing that the license conditions are satisfied.
Compliance Tips for SaaS Businesses
Businesses selling SaaS or software products to Illinois customers should:
- Determine whether the software is canned software;
- Confirm whether the software is intended for general or repeated use;
- Review whether software licenses satisfy Illinois non-taxable conditions;
- Distinguish custom software from standard software;
- Maintain consistent contracts, invoices, and accounting records;
- Retain license agreements and transaction documentation.
Conclusion
Illinois software tax rules can be summarized as follows:
- Canned or prewritten software is generally taxable;
- Electronic delivery does not make canned software non-taxable;
- Software licenses may be non-taxable if specific conditions are met;
- Custom computer software is not taxable if qualifying criteria are met.
For SaaS businesses, Illinois compliance depends on the transaction structure, license terms, and whether the software is canned or custom.
