- These are published sales and use tax rates by jurisdiction. They are not the tax due on a transaction and not a taxability determination: whether an item is taxable, which location's rate applies (sourcing), whether the seller must collect (nexus) and any exemption all change what is owed. Rates come from the Streamlined Sales Tax files the states publish or, where a result's source says so, from the state revenue department's own files and pages; confirm with the state before relying on them.
- Illinois: from the Illinois Department of Revenue's address-specific file (which location and taxing district an address, ZIP+4 or ZIP is in) and its rate files (combined state and local general merchandise rates with effective dates). These are the destination rates remote retailers and marketplace facilitators collect; Illinois retailers' in-state sales can follow origin rules. Rates for qualifying food, drugs and groceries differ and are not returned. An address needs a ZIP; ZIP+4 is the most precise input.
