What is the first step for processing a not authorized state tax exempt transaction?

The first step for processing a not authorized state tax exempt transaction involves entering "HL" followed by five nines. This code is specifically designed to signal the point-of-sale system that you are initiating a transaction that requires special handling due to tax-exempt status. By entering this specific code, the cash register recognizes that the transaction needs to bypass standard tax calculations and allows the cashier to proceed with processing the payment accordingly.

This step is crucial because it sets up the system for the next actions to be taken, ensuring that the transaction is recorded correctly and the customer receives the appropriate tax exemption. Factors such as using the total button, scanning the customer's ID, or calling for a manager would come later in the process but are not the initial actions required to handle the situation.
