California has enacted A.B. 1793, establishing rounding rules for cash transactions across the state. The law affects a wide swath of businesses: retailers, restaurants, personal-service providers — essentially any merchant accepting cash from the public.
The practical impact falls heavily on point-of-sale systems. POS and ERP providers serving California merchants will need to implement the rounding logic, and businesses should confirm their systems are updated before enforcement begins.
Beyond the registers, businesses should train cash-handling staff on the new rules and review how rounding affects cash drawer reconciliation and sales tax reporting.
California businesses should watch for implementing regulations clarifying edge cases, and multi-state retailers should note this is a California-specific requirement.
