The bill introduces a new legal framework for rounding cash transactions to eliminate the need for pennies in Washington State. It allows the total price or change due for in-person cash transactions to be rounded to the nearest five-cent increment, with specific guidelines on how to round based on the final digit of the transaction amount. This rounding applies only to cash payments and does not affect the sales price, taxes, or fees associated with the transaction. Additionally, customers can opt to pay the exact total if they have the exact legal tender. The bill also preempts local regulations that may restrict or penalize rounding practices.

Furthermore, the bill establishes that any taxes and fees must be calculated based on the sales price before rounding adjustments are made. It clarifies that rounding adjustments do not constitute a violation of state or municipal laws and specifies that the rounding provisions do not apply to amounts received from rounding adjustments for tax purposes. The bill includes several new sections added to various chapters of the Revised Code of Washington (RCW), ensuring that the rounding practices are uniformly applied across different types of transactions and do not alter the measures of sales or use tax due.
