For high-earning incorporated professionals, executives, and business owners drawing substantial T4 salary compensation ($200,000+), the annual Registered Retirement Savings Plan (RRSP) contribution limit represents a restrictive artificial ceiling. While an RRSP caps tax-sheltered contributions at approximately $32,490, federal pension legislation permits incorporated enterprises to sponsor a registered Defined Benefit pension plan for a single controlling shareholder: the Individual Pension Plan (IPP). For individuals aged 45 and older, an IPP unlocks drastically higher corporate tax deductions while shielding assets from corporate creditors.
An Individual Pension Plan is a federally registered, CRA-approved Defined Benefit pension established for incorporated business owners. Contributions are 100% tax-deductible to the corporation, bypass personal payroll deductions, and scale exponentially with age—exceeding $45,000 to $60,000+ annually for individuals aged 50 to 65. Furthermore, IPPs allow corporations to make massive one-time past-service funding contributions and absorb investment shortfalls through tax-deductible corporate top-ups.
What Is an Individual Pension Plan (IPP)?
An Individual Pension Plan (IPP) is a CRA-approved defined benefit pension plan sponsored by an incorporated business for a single business owner or key executive. Designed as a superior corporate alternative to an RRSP for individuals over age 40 earning $180,000+ in T4 salary, it provides significantly higher contribution room, corporate tax deductions for past service, and statutory creditor protection.
Unlike an RRSP, where contributions are funded with personal after-tax dollars (and subsequently deducted on a personal T1 return), IPP contributions are paid directly by the corporation as a business expense, reducing corporate taxable income. The investments inside the plan grow completely tax-sheltered until retirement withdrawals begin.
IPP vs. RRSP: Head-to-Head Comparative Architecture
| Feature / Benefit | Traditional RRSP | Individual Pension Plan (IPP) |
|---|---|---|
| Annual Contribution Limit | 18% of earned income capped at ~$32,490 | Actuarially determined; scales from $35,000 to $65,000+/year with age |
| Funding Entity & Deduction | Funded personally; deducted on T1 personal tax | Funded by corporation; 100% deductible corporate expense |
| Past Service Contributions | Not available (restricted to unused room) | One-time corporate deduction of $100k–$300k+ for prior years of T4 |
| Market Deficit Absorption | Market losses permanently destroy capital | Company can make tax-deductible top-up contributions to cover losses |
| Creditor Protection | Varies by province; vulnerable in bankruptcy | 100% protected under provincial and federal Pension Benefit Acts |

When Does an IPP Make Financial Sense? The Threshold Checklist
An IPP is an institutional financial instrument requiring recurring actuarial triennial valuations and administrative compliance. It does not make sense for every entrepreneur. An IPP becomes vastly superior to an RRSP when three conditions are met:
- Age 40–45 or Older: Because actuarial formulas require higher funding reserves to guarantee defined retirement payouts as retirement approaches, contribution room accelerates rapidly after age 45. Below age 40, RRSP limits often exceed IPP baseline room.
- Consistent T4 Salary Over $175,000: IPPs are funded strictly on T4 employment earnings, not corporate dividend draws. If a business owner pays themselves exclusively in dividends, their IPP contribution room is zero.
- Corporate Profitability & Free Cash Flow: The sponsoring company must maintain sufficient recurring net income to support annual mandatory defined benefit pension contributions regardless of market fluctuations.
Past Service Buybacks: The Six-Figure Immediate Corporate Deduction
The single most powerful liquidity event in IPP implementation is the Past Service Buyback. If an incorporated business owner has taken T4 salary from their corporation for 10, 15, or 20 years prior to establishing the IPP, the plan can actuarially credit those past service years.
While an existing RRSP balance is partially transferred to fund the buyback (creating a qualifying transfer), the remaining actuarial past service liability can be funded with a direct cash injection from the corporation. This frequently generates an immediate $100,000 to $300,000 corporate tax deduction in the year of setup, slashing corporate active income taxes during banner fiscal years.
If you are an incorporated entrepreneur over age 45 drawing a six-figure salary, sticking with a generic personal RRSP is leaving massive corporate tax deductions on the table. An IPP allows your corporation to absorb higher contributions, deduct all ongoing investment and management fees, shield your wealth from creditors, and build a fortress-like defined retirement nest egg.
People Also Ask (PAA)
Can I have both an IPP and an RRSP in Canada?
Yes, but IPP contributions generate a Pension Adjustment (PA) that eliminates most of your new annual RRSP contribution room. You retain any previously accumulated unused RRSP contribution room.
Are investment management fees deductible for an IPP?
Yes. All administrative, actuarial, and investment management fees associated with an IPP can be paid directly by the corporation and deducted as a business expense.
What happens to an IPP when the business owner retires or dies?
Upon retirement, the owner can draw a monthly defined pension, purchase an annuity, or transfer the commuted value to a Locked-in Retirement Account (LIRA). On death, surplus assets can roll over tax-free to a surviving spouse’s pension.
