In the case where a remittance return has been submitted by the deadline for filing it (including the case where a remittance return was submitted after the deadline for filing it and the proviso to paragraph (3) or paragraph (9) applies; the same applies in the following paragraph), if a reassessment under the provisions of Article 733-16, paragraph (1) or (3) has been made or an amended return has been submitted, the head of a local government must, where the head finds that there are no justifiable grounds for there having been an error in the amount of the tax base or the amount of tax relating to the remittance return or amended return preceding that reassessment or amended return, collect an amount of additional charge for understatement equal to the amount calculated by multiplying the shortfall amount due to that reassessment or the amount of tax increased by that amended return (referred to as the "covered shortfall, etc." in the following paragraph) by a rate of 10 percent.
