Do I need a Sunnyvale business license?
Generally yes. Businesses operating in Sunnyvale — including home-based and online businesses — must register and pay the City's business license tax. Some exemptions exist, so check the City's rules for your situation.
How to register
- Register online with the City of Sunnyvale Finance Department: official business license page.
- Licenses run on a two-year renewal cycle. Renew by the deadline shown on your City notice — late renewals can bring penalties and back taxes.
Other filings that usually come with it
- Zoning: your use must be allowed where you operate. Some uses (restaurants serving alcohol, gyms, massage, late hours) need a use permit from Sunnyvale Planning.
- Working from home: Sunnyvale's home occupation standards limit customer visits, employees, signage and outdoor storage.
- Trade name (DBA): if you trade under a name other than your legal or registered entity name, file a Fictitious Business Name with the Santa Clara County Clerk-Recorder, then publish it once a week for 4 weeks, starting within 45 days. Renew every 5 years.
- Selling products: taxable sales of goods generally need a free California seller's permit from CDTFA. Sunnyvale's combined sales tax rate is 9.750% as of October 1, 2026.
- Hiring: Sunnyvale's minimum wage is $19.50/hour in 2026 — higher than the state minimum.
