This form is designed for retailers and those registered for use tax, providing a structured method to calculate and remit taxes owed to the state. Key elements of the ST-455 include sections for reporting gross proceeds from sales and rentals, deductions, and net taxable sales.

By adhering to the instructions and submitting the ST-455 on time, businesses can ensure compliance with state tax regulations while avoiding unnecessary penalties.
