Taxation and Finance California 4 Minutes Read · published February 09, 2026 Flag of California

Retailers in Riverside, California must register to collect sales tax before making taxable sales. Most sellers register for a California seller's permit through the California Department of Tax and Fee Administration (CDTFA) and also confirm city-level business tax or license requirements with the City of Riverside Finance Department. This guide explains the registration steps, required forms, enforcement and appeals, and practical action steps to start collecting sales tax legally in Riverside.[1] For city business tax registration and local compliance, check the City of Riverside Business Tax page.[2]

Overview

To collect sales tax you typically need a state seller's permit and compliance with any Riverside business tax or licensing rules. The seller's permit authorizes you to collect and remit California sales and use taxes; the City of Riverside may require a business tax certificate or registration for local business tax purposes. Begin registration before opening for sales or immediately on first taxable sale.

How to register online

  • Apply for a California seller's permit via CDTFA Online Services; follow the registration prompts and supply business details, ownership, and estimated sales.[1]
  • Register with the City of Riverside for any required business tax or business license through the Finance Department or Business Tax portal.[2]
  • Keep records of sales, exemptions, resale certificates, and local tax applicability for audits and returns.
  • Collect the correct combined rate for each sale (state, county, and city components) and remit according to CDTFA filing frequency.
Register the seller's permit before making taxable sales to avoid retroactive liabilities.

Penalties & Enforcement

Enforcement is primarily by the California Department of Tax and Fee Administration for state sales and use tax, and by the City of Riverside for local business tax compliance. Exact monetary fines and schedules are provided on the enforcing agency pages or in applicable statutes; if a specific amount or schedule is not shown on the cited page it is noted below.
