Marketplace Seller laws in Illinois
IDOR’s CRT-63 instructions require a marketplace facilitator assuming a retailer’s or serviceperson’s rights and duties to provide a certificate or similar document showing which taxes it will collect and remit on marketplace sales. The seller or serviceperson keeps it with its books and records; do not mail it to IDOR. Equivalent proof must identify the seller and facilitator, required identifiers, facilitator contact information and dated signature, certification effective date and description of the taxes collected and remitted. The certificate must be renewed annually. This source explains marketplace collection documentation, not every direct-sale obligation, fee, sourcing issue or retained legal-status field.
