SB 1810 requires businesses and public entities accepting cash payments to round transactions to the nearest nickel when exact change isn't available, directly affecting retailers, service providers, and government offices handling cash. It specifies that amounts ending in 1-2 cents or 5-6 cents round down, while 3-4 cents or 7-9 cents round up, using the hundredths place to determine the rounding point. The rule applies only to cash transactions, excluding electronic payments and mixed-tender payments (where only the cash portion is rounded). It explicitly preserves exact sales tax calculations and does not alter non-cash payment systems or tax remittance requirements.
