In the event a business entity subject to calculation of business tax under Section 1 of Chapter 4 of the Act fails to submit the input tax vouchers for deduction from the output tax in the current reporting period, it may defer submission of the vouchers until the following reporting period. If the business entity still fails to do so in the following reporting period, it shall, in the reporting period when it actually submits the vouchers for deduction from the output tax, specify the reasons. However, the time period for submission of the input tax vouchers for deduction from the output tax shall be limited to ten years.
