Amortisation of voluntary retirement payments spreads deduction over the prescribed statutory period for computing business profits. Payments under a voluntary retirement scheme are amortisable: an initial portion is deductible in the year of payment and the balance in equal instalments over the four immediately succeeding previous years. The amortisation provisions apply to successor entities on amalgamation, demerger or specified reorganisations as if no transfer had occurred, provided the successor meets the qualifying conditions. No deduction is allowed for the transferor in the year of amalgamation, demerger or succession, and the expenditure is not deductible under any other provision of the Act.
