Frequently asked questions
What is the Illinois sales tax rate?
6.25% state on general merchandise, with local taxes on top. Chicago exceeds 10%. Qualifying food, drugs and medical appliances are taxed at a reduced 1% state rate.
What is the difference between ROT and Use Tax?
Retailers' Occupation Tax is charged on sellers with a physical presence in Illinois and includes local rates; Use Tax was historically the state-only rate for remote sellers. The rules shifted so that remote sellers now generally collect destination rates — confirm current guidance, as this has changed more than once.
Is shipping taxable in Illinois?
It depends on whether the delivery charge is part of an inseparable transaction. Separately stated charges where the customer had a genuine option to collect are generally not taxable; bundled charges are.

$100,000 in sales or 200 separate transactions into Illinois over the preceding twelve months.
