How an IPP Helps Incorporated Business Owners Reduce Taxes
If you run an incorporated business, taxes probably feel like a partner who takes too much and contributes too little. And if you’re like most owners, retirement planning usually gets pushed to “later.”
That’s where an IPP — an Individual Pension Plan — can help.
It’s one of the cleanest, most efficient ways for your corporation to save on taxes while building your retirement income.
What an IPP Really Is
An IPP is a pension plan your corporation sets up for you.
You earn T4 income.
Your business makes contributions.
Those contributions grow for your retirement — and the corporation gets the tax deduction.
Think of it as the corporate version of an RRSP, but with more room and more benefits once you’re over 40.
How an IPP Reduces Taxes
1. Corporate Contributions Are Fully Deductible
With RRSPs, you contribute personally.
With an IPP, your business pays, and every dollar is a deductible expense.
This lowers corporate taxable income immediately.
Simple and effective.
2. Higher Contribution Limits After Age 40
Once you hit 40, an IPP allows larger contributions than an RRSP every single year.
More room =
bigger deductions
more tax-efficient savings
faster retirement growth
It’s also a great way to “catch up” if you spent years building the business instead of saving.
3. Extra Deductions RRSPs Don’t Offer
IPP rules include additional corporate deductions, such as:
Past service (buying back earlier working years)
A final large contribution at retirement
Deductible plan and actuarial fees
None of these benefits exist with an RRSP.
Why the CRA Is Fine With This
The government wants incorporated professionals to have reliable retirement income.
A well-funded pension reduces future strain on public programs.
So the CRA essentially says: “If your corporation builds you a real pension, we’re OK giving you the deduction.”
