How Chicago sales and use tax works

Retailers must collect applicable sales tax at the point of sale on taxable goods and certain services, and remit those taxes through the appropriate returns. The total tax rate typically includes state, county, and city components and may vary by product type, delivery method, and point of sale nexus. For official rate schedules and locality breakdowns consult the municipal finance page cited above [1].

Penalties & Enforcement

The City and state enforce sales and use tax compliance through assessments, penalties, and collection actions. Specific monetary penalties and interest schedules for late payment, late filing, or failure to collect may be set out on the enforcing authority's pages; where amounts or escalation rules are not reproduced on the cited municipal page, the text below states that fact and points to the enforcement office.

  • Monetary fines and interest: not specified on the cited page; consult the enforcing office for exact rates and interest calculations.
