A pooled registered pension plan (PRPP) is a type of pension plan that is similar to a defined contribution plan; however, employer contributions are not mandatory. A PRPP pools contributions together to achieve lower costs in relation to investment management and plan administration.

You should verify with your employer if they are contributing to a PRPP on your behalf. Any voluntary contributions made by your employer are not included in your income, and therefore not deductible on your income tax return.
