San Francisco states business registration renewal is due the last day of February beginning in 2026 (unified annual registration and tax form)

An official SF.gov small business newsletter indicates that beginning in 2026, San Francisco business registration renewal is due on the last day of February and will be part of a unified Annual Business Registration and Tax Form (linked to Proposition M business tax reform). Vendors operating in San Francisco should update compliance calendars and ensure renewal and associated annual filing processes are completed by the new end-of-February deadline to maintain active registration for lawful operations and city contracting eligibility where applicable.
