How reporting works

Many cities, including Riverside, base certain local business taxes on gross receipts or have classifications that refer to gross receipts tiers. Businesses should keep accurate sales and revenue records, prepare an annual or periodic business tax return as required by the city, and remit any payment by the due date stated on the notice or return. If your business holds franchise agreements (for utilities, cable, or similar), separate franchise fees or taxes may be assessed by contract terms or by state rules.
