The provisions of Article 25, paragraph (3) (Transitional Provisions Concerning Withholding on Pensions Deemed to Be Salary or Other Wage) of the Supplementary Provisions of the new Act apply to pensions prescribed in that paragraph that are to be paid on or after the effective date, and the provisions then in force continue to govern such pensions that were to be paid before that date.

A person who, before the effective date, filed a return under Article 127 (Final Return in the Case of Absence From Japan Partway Through the Year) of the former Act (including as applied mutatis mutandis pursuant to Article 166 (Application Mutatis Mutandis to Nonresidents) of the former Act) for income tax for 1969, and a person who, before that date, received a determination under Article 25 (Determination) of the Act on General Rules for National Taxes (Act No. 66 of 1962) for income tax for that year, may, if a change is to arise as a result of the application of the provisions of the new Act in the particulars stated in that return or the particulars relating to that determination (or, if a Reassessment under Article 24 (Reassessment) or Article 26 (Re-reassessment) of that Act was made with respect to those particulars before that date, the particulars after that Reassessment), file a request for Reassessment under Article 23, paragraph (1) (Request for Reassessment) of the Act on General Rules for National Taxes with the district director by March 31, 1970, with respect to the particulars in which that change is to arise.

In the case where a Reassessment under Article 24 or Article 26 of the Act on General Rules for National Taxes is made based on a request for Reassessment referred to in the preceding paragraph, when interest on refund prescribed in Article 58, paragraph (1) (Interest on Refunds) of the Act on General Rules for National Taxes is calculated for a refund under Article 159, paragraph (2) (Refund of Withheld Tax and Similar Amounts upon Reassessment or Determination) of the new Act (including as applied mutatis mutandis pursuant to Article 168 (Application Mutatis Mutandis to Nonresidents) of the new Act), the period referred to in that paragraph that forms the basis for the calculation is the period from the effective date until the day on which the decision to pay the refund is made or the day on which Appropriation under Article 57, paragraph (1) (Appropriation) of that Act (hereinafter referred to as "Appropriation") of that refund is made (or, if there is a day before that date on which the refund became suitable for Appropriation, that day).

If the amount of income tax collected pursuant to the provisions of Articles 199 through 202 (Withholding on Retirement Income) of the former Act on severance pay or other such compensation that was to be paid in 1969 and was paid before the effective date exceeds the amount of income tax that would result from applying to that severance pay or other such compensation the provisions of Article 201 (Amount of Tax Withheld from Retirement Income) and Article 202 (Withholding on Lump-Sum Retirement Payments Deemed to Be Retirement Income) of the new Act as replaced pursuant to Article 3, paragraph (1) (Special Provisions on the Calculation of Income Deductions and Tax Amounts for Income Tax for 1969) of the Supplementary Provisions, the Resident who received the payment of that severance pay or other such compensation may, as provided by Cabinet Order, claim a refund of the excess amount from the district director with jurisdiction over the place for tax payment by June 30 of that year.

If a claim for refund under the preceding paragraph is made with respect to severance pay or other such compensation prescribed in that paragraph, with regard to the application of the provisions concerning returns, Reassessments or determinations, payment, collection (excluding withholding on severance pay or other such compensation), and refunds (excluding the refund for which that claim is made) for that Resident's income tax for 1969, and the application of the provisions of Article 201, paragraph (1), item (ii) of the new Act as replaced pursuant to Article 3, paragraph (1) of the Supplementary Provisions to severance pay or other such compensation to be paid in that year that is paid on or after the effective date, income tax is deemed to have been collected in the amount obtained by deducting the amount to be refunded under that claim from the amount of income tax collected pursuant to the provisions of Articles 199 through 202 of the former Act on the severance pay or other such compensation for which that claim is made.

In the case where interest on refund prescribed in Article 58, paragraph (1) (Interest on Refunds) of the Act on General Rules for National Taxes is calculated for a refund under paragraph (1), the period referred to in that paragraph that forms the basis for the calculation is the period from the day following the day on which one month has elapsed from the day on which the claim for refund under paragraph (1) was made until the day on which the decision to pay the refund is made or the day on which Appropriation of that refund is made (or, if there is a day before that date on which the refund became suitable for Appropriation, that day).
