  2. A seller located outside Illinois but that has a contract with a person located in Illinois under which the person, for a commission or other consideration based upon the sale of tangible personal property by the seller, directly or indirectly refers potential customers to the seller by providing to the potential customers a promotional code or other mechanism that allows the seller to track purchases referred by such persons. The provisions of this paragraph (2) shall apply only if the cumulative gross receipts from sales of tangible personal property by the seller to customers who are referred to the seller by all persons in Illinois under such contracts exceed $10,000 during the preceding 4 quarterly periods ending on the last day of March, June, September, and December.

A retailer, who does not have a physical presence or any selling activities in Illinois (see 86 Ill. Adm. Code 270.115), that sells tangible personal property to Illinois purchasers and meets a tax remittance threshold. A remote retailer is considered an Illinois retailer and is liable for all applicable state and local sales tax administered by IDOR on all retail sales to Illinois purchasers. A retailer that fulfills any orders from its inventory in Illinois is not a "remote retailer".

Sales Tax (Retailers' Occupation Tax [ROT])

A tax imposed on retailers selling tangible personal property to purchasers in Illinois. It includes the taxes levied under the Retailers' Occupation Tax Act (35 ILCS 120) and all applicable local retailers' occupation taxes administered by IDOR. Out-of-state sellers, remote retailers, and marketplace facilitators, see the Leveling the Playing Field for Illinois Retail Act Flowchart to determine which tax you are to collect. There is no authority for remote retailers to voluntarily collect sales tax. 

Destination rate sales tax - The tax rate in effect at the location to which the tangible personal property 

  • is shipped or delivered or 
  • at which possession is taken by the purchaser.

Origin rate sales tax - The tax rate in effect at the location of the Illinois inventory from 

  • which a sale is fulfilled or 
  • where selling activities occur (e.g., brick and mortar store in Illinois or your home office in Illinois). 

Tax remittance thresholds - marketplace facilitator

A marketplace facilitator selling tangible personal property at retail in Illinois is subject to Illinois sales tax if either of the following thresholds is met:

  • $100,000 or more in cumulative gross receipts from sales of tangible personal property to purchasers in Illinois made through the marketplace by the marketplace facilitator and by marketplace sellers; or 

  • 200 or more separate transactions for the sale of tangible personal property to purchasers in Illinois by the marketplace facilitator and marketplace sellers selling through the marketplace.

Tax remittance thresholds - remote retailer

A remote retailer selling tangible personal property at retail in Illinois is subject to state and local sales tax if either of the following thresholds is met:

  • $100,000 or more in cumulative gross receipts from sales of tangible personal property to purchasers in Illinois; or 

  • 200 or more separate transactions for the sale of tangible personal property to purchasers in Illinois.

Use

The exercise by any person of any right or power over tangible personal property incident to the ownership of that property.

Use Tax

A tax imposed upon the privilege of using in Illinois tangible personal property purchased at retail from a retailer. Use Tax is not a destination-based tax. It is flat rate throughout the state of 6.25% for general merchandise and 1% for qualifying food, drugs and medical appliances. Out-of-state sellers, remote retailers, and marketplace facilitators, see the Leveling the Playing Field for Illinois Retail Act Flowchart to determine which tax you are to collect. 

Voluntary use tax collector

Although not required, a remote retailer who does not meet either threshold may collect Illinois Use Tax as a courtesy to its customers. Illinois purchasers incur an Illinois Use Tax liability on out-of-state purchases that do not have Illinois sales or use tax collected and remitted by the seller.
