If the amount of income tax collected pursuant to the provisions of Articles 199 through 202 (Withholding from Retirement Income) of the former Act on severance pay or other such compensation payable during 1975 which was paid before the effective date exceeds the amount of income tax that would result from applying the provisions of Articles 201 and 202 of the new Act to that severance pay or other such compensation, the Resident who received payment of that severance pay or other such compensation may, pursuant to the provisions of Cabinet Order, request the district director with jurisdiction over the place for tax payment to refund the excess amount by June 30 of that year.
