Taxation and Finance California 4 Minutes Read · published March 08, 2026

Redwood City, California businesses must follow state sales tax rules while complying with local licensing and enforcement. This guide explains when food sales are taxable, how retailers must register and remit tax, and where to find official forms and contacts for both the City and the California Department of Tax and Fee Administration (CDTFA). It highlights common compliance pitfalls and provides action steps to register, collect, remit, and appeal assessments.

How sales tax and food exemptions apply

California law generally exempts most unprepared food for human consumption from sales tax, while prepared foods and some grocery items are taxable. Retailers in Redwood City must review the CDTFA guidance to determine whether a specific product is taxable, including rules about heating, packaging, and on-site consumption. For official taxability criteria, see the CDTFA guidance on food products^[2].

Check CDTFA categories before pricing or advertising food as "tax-exempt".

Registering and collecting tax

Any business selling tangible personal property at retail in Redwood City must generally hold a California seller's permit and collect the appropriate state and local sales taxes. Apply for a seller's permit through the CDTFA; the online registration page explains required information and filing frequency^[3]. Separate Redwood City business license or registration may also be required; contact the City's Business License office for local requirements and filings^[1].
