A Supplemental Executive Retirement Plan is generally an unregistered deferred compensation arrangement designed to provide highly compensated employees with retirement benefits beyond limits available through registered retirement arrangements.
Where the SERP is structured as an unfunded or notional arrangement, the employer normally records the promised benefit as an obligation rather than receiving an immediate deduction for a funded registered-plan contribution. The employer's deduction generally arises when the benefit is ultimately paid and becomes taxable compensation to the executive. Canadian SERP structures commonly use this deferred-deduction treatment.
This is an important distinction from a registered pension plan. A SERP is not simply registered with CRA so that unrestricted deductible contributions may be made. Its principal purpose is precisely to supplement benefits limited by the tax rules governing registered retirement arrangements.
A funded SERP can also involve a Retirement Compensation Arrangement, which brings a separate tax regime, including refundable tax on contributions to the RCA custodian. Therefore, the precise tax consequences depend on funding structure.
For the examination scenario, option C describes the core tax consideration associated with a conventional unfunded SERP: the employer's tax deduction is deferred until the retirement benefit is paid.
