An Individual Pension Plan (IPP) is a defined benefit pension plan that offers higher tax-deductible contributions and accelerated tax-deferred growth compared to a RRSP. It provides a guaranteed lifetime retirement income based on a formula of the member's age, salary, and years of service. Key advantages include guaranteed pension benefits, potential for higher contributions, ability to make past service contributions, and creditor protection. However, it also has disadvantages like reduced RRSP limits, inability to access funds before retirement, and higher setup and administration costs than other plans. An IPP may be suitable for business owners, executives, or employers seeking enhanced retirement benefits for key employees.
