## Selling into Cook County: Illinois rules

- **What's taxable:** At the state level, SaaS is exempt, clothing is taxable, groceries are partly taxable and digital goods are exempt.
- **Economic nexus:** Illinois economic nexus is triggered when your cumulative gross receipts from sales into the state reach $100,000 over the preceding 12 months. The 200-transaction test was removed effective January 1, 2026, so the dollar threshold is the only economic trigger.
- **Filing:** Illinois assigns monthly, quarterly, or annual filing based on prior-year liability. Returns (Form ST-1) are due the 20th of the month following the reporting period.
