①A person who, before the effective date, filed a return under Article 29, paragraph (2) or the second sentence of paragraph (3) (Returns in the Case of Absence From Japan) of the former Act for income tax for 1965, or who, before that date, received a determination with respect to income tax for that year, may, if the particulars stated in that return or the particulars concerning that determination (or, if a Reassessment of those particulars was made before that date, the particulars after that Reassessment) come to change as a result of the application of the provisions of the new Act, make a request for Reassessment under Article 23, paragraph (1) (Requests for Reassessment) of the Act on General Rules for National Taxes to the district director by June 30 of that year with respect to the particulars that come to change.

②Where a Reassessment is made based on a request for Reassessment under the preceding paragraph, when interest on refund 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 Article 58, paragraph (1) (Interest on Refunds) of the Act on General Rules for National Taxes which serves as the basis for that calculation is the period from the effective date to the date on which the decision to pay out that refund is made or the date on which an Appropriation of that refund is made (or, if there is a date before that date on which the refund became suitable for Appropriation, that date).
