Income Tax Act Article 100

The tax authority shall, after having determined the annual income of a taxpayer, make out and serve on him/her/it a tax demand notice giving the balance of the tax payable for the full taxable year after deducting the provisional payment, the tax withheld yet to be offset, the amount of tax credits as specified in Paragraph 4 of Article 15, and other payments of the tax. However, the withholding tax from income subject to separate taxation in accordance with this Act shall not be deductible.In case the tax as determined payable for annual settlement falls short of the total amount of tax paid, the tax authority shall make out and issue to the taxpayer a refund notice or an exchequer's check for refunding the overpaid amount of income tax.If, thereafter any tax is decided upon as additionally payable or refundable pursuant to a recheck result, or a decision made on an administrative appeal or an administrative litigation, the tax authority shall make out and deliver to the taxpayer a tax demand notice, a revenue refund notice, or an exchequer's check for refunding the overpayment or for demanding the full payment of the tax payable. The taxpayer liable for additional tax shall, within ten days after service of the foregoing tax demand notice, fully pay the income tax obligation.In the case of a refund as provided in the preceding two paragraphs, the tax authority shall, promptly and no later than ten days from the date of verification, fill out and serve to the taxpayer a tax refund notice or an exchequer's check. The period for refunding the overpayment shall be three months commencing from the date of service of the tax refund notice to the taxpayer. Upon expiration of the said refunding period, no refund will be made.Where the amount of retained surplus profits declared by a taxpayer under Article 102-2 hereof is verified as being underdeclared or overdeclared, the provisions set out in Paragraphs 1 through 4 of this article shall apply mutatis mutandis to the supplemental payment of the shortfall tax or the refund of the overpaid tax.
