Who must collect sales tax

Retailers with a physical presence, a nexus under Illinois law, or those meeting economic thresholds must collect sales tax on taxable transactions made in Aurora. Local municipal taxes that apply inside Aurora are administered through the Illinois Department of Revenue, and the city requires applicable local business licensing for some activities.[2]

If you sell tangible personal property in Aurora, confirm both state registration and any city license requirements.

Rates, calculation and point-of-sale rules

Retailers must charge the combined state, county and municipal sales tax rate that applies to the delivery location. Use the Illinois Department of Revenue rate lookup for current combined rates and district surtaxes before charging customers.[3]

  • Calculate tax using the rate applicable to the buyer's delivery or pickup location.
  • Display sales tax on receipts where required by Illinois rules.
  • Keep sales, exemption and resale records for the period required by Illinois law.
