Where a return filed by the due date (including a return of refund claim; the same applies in paragraph (3)) has been filed (including where a return filed after the due date has been filed and the proviso to paragraph (1) or paragraph (9) of the following Article applies), if an amended return has been filed or a reassessment has been made, penalty tax for understatement is imposed on the taxpayer in an amount equivalent to the amount calculated by multiplying the tax amount payable under the provisions of Article 35, paragraph (2) (Payment of National Tax using the Self-Assessment System) based on the amended return or reassessment by 10% (or by 5% if the amended return was not filed in anticipation that a reassessment would be made of the national tax pertaining to the return because an examination had been conducted with regard to that national tax).
