After receiving the business tax return, the competent tax authority shall, within six months counting from the day following the expiration of the filing period set forth in Article 35, assess the sales amount and the business tax payable or overpaid.
When a taxpayer voluntarily files a supplementary tax return with the competent tax authority and makes a supplementary payment for the amount of tax owed, the competent tax authority shall assess the filing within six months from the day following its receipt of the same.
With respect to cases required to be assessed by the competent tax authority under paragraph 1 above, if there is no supplementary payment of tax due or refund of tax due, the competent tax authority may make a public announcement, specifying that the assessment is made based on the information in the tax return declared by the business entity, in lieu of delivering a notice of the assessed tax amount.
