The bill introduces new provisions to Washington state law regarding the adjustment of cash transaction prices to eliminate the need for pennies. It adds two new sections to chapters 82.08 and 82.12 of the Revised Code of Washington (RCW). Under these provisions, if a transaction's total price ends in one cent, two cents, six cents, or seven cents, it will be rounded down to the nearest amount divisible by five cents. Conversely, if the total ends in three cents, four cents, eight cents, or nine cents, it will be rounded up to the nearest amount divisible by five cents. These adjustments apply only to transactions made with legal tender and do not affect payments made through other methods such as credit cards or electronic payments.

Additionally, the bill defines key terms such as "legal tender," "total price," and "transaction" to clarify the scope of the new regulations. It mandates that the department will establish rules for transactions that involve a combination of legal tender and other payment forms. This legislative change aims to streamline cash transactions and reduce the inconvenience associated with handling pennies in everyday purchases.
