It is written for retailers, nonprofit purchasers, tax preparers, and residents seeking clear action steps to verify exemption status and resolve disputes.

Which items are typically exempt or taxable

Exemptions commonly cover food for home consumption and certain basic necessities; however, definitions vary by category and by whether the item is prepared for immediate consumption. Retailers must rely on the Illinois Department of Revenue definitions and City of Chicago collection rules when deciding tax treatment.

  • Groceries for home consumption — generally exempt under state rules but subject to specific definitions.
  • Prepared food and restaurant sales — often taxable under state definitions.
  • Beverages and candy — classification depends on state criteria and may be taxable.
  • Medical necessities and certain hygiene products — some are exempt, others are not, per statutory language and administrative guidance.
Check item definitions with the Illinois Department of Revenue before deciding tax treatment.

How exemptions are applied in Chicago

Chicago collects local sales taxes that are administered in coordination with Illinois tax authorities. Retailers register with state filing systems and apply exemptions at the point of sale when a sale clearly meets the exemption criteria or when the purchaser presents an authorized exemption certificate. Nonprofit purchases may require documentation per state or municipal guidance.

  • Exemption certificates and resale certificates — used when applicable by purchaser type.
  • Recordkeeping — maintain supporting documentation to prove exemption eligibility.
  • Registration — businesses must register to collect and remit taxes as required by state and local rules.
Retain exemption documentation for the entire audit period specified by tax authorities.
