RIDGE 3: TAX EFFICIENCY
IPP vs RRSP for Business Owners in Canada
An Individual Pension Plan lets your corporation contribute significantly more to your retirement than an RRSP allows, and the gap gets wider every year after age 40. In 2026, the maximum RRSP contribution is $32,490 regardless of your age. An IPP contribution for a 50-year-old earning a T4 salary of $175,000 can exceed $58,000, all as a tax-deductible expense to your corporation. That is an additional $25,000 or more per year sheltered from tax that your RRSP simply cannot accommodate. The IPP is a defined benefit pension plan, which means your retirement income is guaranteed based on a formula, and if the investments underperform, your corporation can make tax-deductible top-up contributions to cover the shortfall. Your RRSP has no such mechanism. An IPP also offers full creditor protection as a registered pension, and it allows you to buy back past service years going as far back as 1991, potentially creating a large one-time corporate deduction. The catch: an IPP requires actuarial setup, annual valuations, and regulatory filings. It is not for everyone. But if you are an incorporated professional over 40 earning a T4 above $100,000, the math almost always favours the IPP.
The Tax Landscape
How Canadian tax brackets actually work, and why it matters for planning.
Canada uses a progressive tax system. That means you do not pay one flat rate on all your income. Instead, each dollar is taxed at the rate for the bracket it falls into. Your first $55,867 (federally) is taxed at 15%, and only the income above that threshold moves into the next bracket.
This distinction between marginal rate (the rate on your next dollar) and average rate (your total tax divided by total income) is the foundation of every tax strategy. When someone says "I'm in the 30% bracket," they mean their marginal rate is 30%, not that all their income is taxed at 30%.
Why this matters for planning: RRSP deductions save tax at your marginal rate. If you contribute $10,000 while in the 30.5% bracket, you save $3,050 in tax. If you withdraw that same $10,000 in retirement while in the 25% bracket, you pay $2,500. The difference is the planning opportunity.

TFSA vs RRSP
The most common question in Canadian financial planning. Here is how to think about it.
Feature
RRSP
TFSA
Tax on contribution
Deductible (reduces taxable income)
After-tax dollars (no deduction)
Tax on growth
Tax-deferred (taxed on withdrawal)
Tax-free (never taxed)
Tax on withdrawal
Fully taxable as income
Completely tax-free
Contribution room
18% of earned income (max ~$32K)
$7,000/year (2025), cumulative
Impact on benefits
Withdrawals count as income (GIS, OAS)
No impact on income-tested benefits
Best when
High income now, lower in retirement
Lower income now, or want flexibility
Spousal option
Yes (income splitting strategy)
No (but each spouse has own room)
The decision is not "which is better." It is "which is better for your situation right now." Most Canadians benefit from using both. The question is which to prioritize when you cannot max out both. The flowchart below walks through the key decision points.
If your tax rate is the same at contribution and withdrawal, the TFSA and RRSP produce mathematically identical after-tax results. The RRSP gives you a bigger account balance (because you invested the tax savings), but you owe tax on withdrawal. The TFSA gives you a smaller balance, but it is all yours. The difference shows up when rates change between contribution and withdrawal, or when government benefit clawbacks enter the picture.
Corporate Tax Concepts
How incorporated professionals and business owners think about tax structure.
Corporate tax planning is complex and highly specific to your situation. This section explains general concepts for educational purposes. Implementation requires a CPA and, in many cases, a tax lawyer. Do not act on this information without professional guidance.
When a Canadian professional incorporates (doctors, dentists, lawyers, consultants, business owners), they gain access to the small business deduction. The first $500,000 of active business income is taxed at the small business rate, which in Alberta is approximately 11% combined (federal 9% + provincial 2%). Compare that to the top personal marginal rate of 48%.
The gap between the corporate rate and the personal rate creates a tax deferral opportunity. Money left inside the corporation is taxed at the lower rate. It is only taxed again at the personal level when it is paid out as salary or dividends. The strategy is not about avoiding tax permanently. It is about controlling when you pay it.
Illustrative: $300,000 Business Income in Alberta
As Personal Income
~$102,000
estimated tax (avg ~34%)
~$198,000 after tax
Kept in Corporation
~$33,000
corporate tax (~11%)
~$267,000 to invest
The $69,000 difference is a deferral, not a savings. It will be taxed when paid out personally. The benefit is having more capital working for you in the meantime.
Many incorporated professionals set up a holding company (HoldCo) above their operating company (OpCo). Surplus cash flows up from OpCo to HoldCo as inter-corporate dividends (generally tax-free between connected Canadian corporations). The holding company then invests those funds, providing asset protection if the operating company faces liability.
This structure also facilitates estate planning (shares of HoldCo can be structured for estate freezes) and can provide flexibility for income splitting with family members who are shareholders, subject to the Tax on Split Income (TOSI) rules.
Income Splitting
Legal ways to shift income to lower-taxed family members.
Because Canada taxes individuals (not families), a household where one spouse earns $200,000 and the other earns $0 pays significantly more tax than a household where both earn $100,000. Income splitting strategies attempt to shift income from the higher-rate spouse to the lower-rate spouse within the rules.
The CRA's attribution rules and Tax on Split Income (TOSI) rules limit many splitting strategies. Understanding what is permitted and what triggers attribution is essential before implementing any approach.
Spousal RRSP
Permitted
Higher earner contributes, claims deduction. Lower earner withdraws at their rate after 3-year hold.
Pension Income Splitting
Permitted (age 65+)
Up to 50% of eligible pension income can be allocated to spouse on tax return.
Spousal Loan at Prescribed Rate
Permitted (with formalities)
Lend to lower-income spouse at CRA prescribed rate. They invest, report income at their rate.
CPP Sharing
Permitted (both 60+)
Spouses can share CPP benefits based on years of cohabitation during contribution period.
Paying Salary to Family
Must be reasonable
Corporation can pay family members for actual work performed at a reasonable rate.
Gifting to Adult Children
No attribution (adults)
Gifts to adult children (18+) do not trigger attribution. Investment income is theirs.
Withdrawal Order
The sequence you draw from accounts in retirement can save or cost thousands per year.
Accumulation gets most of the attention, but the order in which you draw from your accounts in retirement has a significant impact on your after-tax income and government benefit eligibility. Drawing too much from the RRIF too early can trigger OAS clawbacks. Drawing too little can result in a large taxable estate.
The general framework below is a starting point. Your optimal withdrawal sequence depends on your specific income sources, account balances, tax bracket, and benefit eligibility. A retirement income plan models this in detail.
General Withdrawal Priority
This is a simplified framework. Your optimal order depends on your specific tax situation.
Non-Registered
Withdraw first (only gains taxed)
RRSP / RRIF
Convert at 71, draw strategically
TFSA
Withdraw last (tax-free, no clawback)
CPP + OAS
Government benefits (income-tested)
Non-registered accounts generate annual taxable events (interest, dividends, capital gains) whether you withdraw or not. Drawing from these accounts first reduces the ongoing tax drag. Only the capital gains portion is taxable (at 50% inclusion rate for the first $250,000 annually), and you recover your original cost base tax-free. Meanwhile, your RRSP and TFSA continue to grow tax-sheltered.
