Illinois will eliminate their previous 200 transaction count threshold for remote sellers effective January 1, 2026.

Effective January 1, 2026, Illinois will eliminate their previous 200 transaction count threshold for remote sellers. Remote sellers hitting or exceeding $100,000 in sales are now mandated to register in the state. Businesses can deregister or defer initial registration regardless of the number of transactions so long as they are under the $100,000 sales threshold in a 12 month period. Given the new threshold, it is important to stay on top of the states you need to get registered in. Sales Tax and More offers many services to help you stay or get compliant in the necessary states.
