If the person required to file is required to pay an additional tax under this article pursuant to such amended return, he shall pay such additional tax, together with interest as provided in section 39-23.5-109, at the same time he files the amended return, subject, however, to any extension or installment election under section 39-23.5-108.

If any additional tax is due under this article by reason of such determination or redetermination, the person required to file shall pay the same, together with interest as provided in section 39-23.5-109, at the same time he files such notice, subject, however, to any extension or installment election under section 39-23.5-108.
