Earning more is a goal. Keeping more of it? That's a strategy.
If your household income is above $200,000 or you own a business, hold investments, or receive dividends, the standard tax tips don't fully apply to you. Your tax situation is more complex, and the cost of not planning is proportionally higher. In Ontario, the top combined federal and provincial marginal rate hits 53.53% on income above $253,414. That means without proactive planning, more than half of every additional dollar you earn goes to tax.
This week's deep dive covers the most effective, CRA-compliant strategies available to high-income Canadians in 2025 with the numbers to back them up.
The High-Income Tax Challenge
Canada's progressive tax system means that as your income grows, an increasing share of each additional dollar earned goes to the government. Here's how the combined federal + Ontario marginal rates stack up for 2025:
Taxable Income (Ontario) | Combined Marginal Rate (2025) |
Up to $57,375 | 20.05% |
$57,376 – $102,894 | 26.30% |
$102,895 – $111,733 | 33.30% |
$111,734 – $150,000 | 43.41% |
$150,001 – $177,882 | 46.41% |
$177,883 – $220,000 | 48.19% – 51.97% |
Above $253,414 | 53.53% |

The goal of high-income tax planning isn't avoidance, it's using every legitimate tool available to reduce the amount of income exposed to those top rates. Here's where to start.
1. Income Splitting Strategies
The most powerful lever available to high-income Canadians is shifting taxable income from a high-rate earner to a lower-rate family member, legally and permanently.
Prescribed Rate Loans (Spousal Loans)
A prescribed rate loan allows the higher-income spouse to lend money to the lower-income spouse at the CRA's official prescribed rate. The lower-income spouse invests the funds, and the investment income is taxed at their lower rate, not attributed back to the higher earner.
📌 Key Facts: Prescribed Rate Loans (Q2 2026) Current CRA prescribed rate: 3% (Q1-Q2 2026, per Investment Executive, verified March 2026) Interest must be paid by January 30 of the following year, not a day late Rate is locked in at the time the loan is established Funds must be used for investment purposes A formal written loan agreement is required |
With a 3% prescribed rate, this strategy becomes most beneficial when the investment return on the loaned funds exceeds 3%, the net spread is taxed at the lower spouse's rate. The larger the rate differential between spouses, the greater the long-term saving.
⚠️ Important If the January 30 interest payment deadline is missed by even one day, the attribution rules apply for that year and all future years. The loan must be restructured at the current prescribed rate to restart the strategy, which may trigger capital gains. |
Family Trusts
An inter vivos (living) family trust can distribute income to adult beneficiaries in lower tax brackets, including adult children, a lower-income spouse, or parents. The trust pays tax only on income it retains; distributed income is taxed in the hands of beneficiaries.
Family trusts are more complex to establish and administer than prescribed rate loans, and the Tax on Split Income (TOSI) rules significantly restrict income splitting with minor children and, in some cases, adult family members who are not actively involved in the business. Professional legal and tax advice is essential before establishing a family trust.
2. Canadian Controlled Private Corporation (CCPC) Structures
For business owners, incorporating as a CCPC offers some of the most powerful tax deferral tools available in Canada.
The Small Business Deduction
A CCPC can access the small business deduction (SBD) on the first $500,000 of active business income, reducing the federal corporate tax rate to 9% (versus the general rate of 15%). Ontario's combined rate on SBD income is approximately 12.2% compared to the top personal marginal rate of 53.53%.
The difference between the corporate rate and your personal marginal rate creates a significant deferral opportunity. Retaining earnings inside the corporation and drawing them out strategically in lower-income years amplifies this advantage.
⚠️ Passive Income Grind-Down If your CCPC earns more than $50,000 of passive investment income in a year, the SBD is gradually reduced, it's eliminated entirely at $150,000 of passive income. Managing passive income accumulation inside a CCPC is an important planning consideration. |
Salary vs. Dividend Optimization
A key decision for incorporated professionals and business owners is how much to pay yourself as salary versus eligible dividends. There's no universal answer, it depends on your corporate tax rate, personal marginal rate, CPP contribution goals, RRSP room, and provincial rules.
Factor | Salary |
CPP contributions | Creates contribution room, builds benefit |
RRSP room | Creates 18% contribution room |
Personal marginal rate | Fully taxable at marginal rate |
Corporate cost | Deductible expense |
Complexity | Simpler payroll |
Most CCPC owners benefit from a combination of enough salary to maximize RRSP room and CPP benefits, with eligible dividends making up the balance. A CPA should run an annual optimization model for your specific numbers.
3. RRSP Maximization
At a 53.53% marginal rate, the math on RRSP contributions is compelling. Every $32,490 contributed (the 2025 maximum) generates up to $17,382 in immediate tax relief at the top rate plus decades of tax-deferred compound growth.
For high-income earners, the key strategies go beyond simply contributing the maximum:
Carry-forward room: If you have unused RRSP contribution room from prior years, this can be deployed in high-income years for outsized deductions.
Pension income splitting: Converting RRSP to RRIF after age 65 allows up to 50% of eligible pension income to be attributed to a lower-income spouse. A powerful late-stage income splitting strategy.
Late deduction: Contribute now, but defer claiming the deduction to a future year when income is higher or claim it against specific income events like a business sale or bonus year.
4. Individual Pension Plan (IPP)
An Individual Pension Plan is a defined benefit pension plan for incorporated business owners and professionals, typically those over age 40 with T4 income exceeding $100,000. An IPP allows contributions significantly larger than RRSP limits, the older the plan member, the larger the permitted contribution.
📌 IPP vs. RRSP: Key Differences IPP contributions are 30-65%+ higher than RRSP limits for individuals over 50 All contributions are corporate tax deductions The defined benefit structure provides pension income certainty in retirement Creditor protection is generally stronger than an RRSP Setup and administration costs are higher, typically requires an actuary Transfers to a RRSP or RRIF are possible on wind-up |
An IPP makes the most sense for business owners who have already maximized their RRSP and are looking for additional tax-sheltered retirement savings. Consult a pension specialist to determine if the contribution advantage justifies the administration costs at your income level.
5. Capital Dividend Account (CDA)
When a CCPC sells capital property, only the taxable portion of the capital gain (50% under the current 2025 rules) is included in corporate income. The other 50%, the non-taxable portion flows into the Capital Dividend Account (CDA).
Amounts in the CDA can be paid out to shareholders as capital dividends, completely tax-free to the recipient. This is one of the most tax-efficient ways to extract wealth from a corporation.
The CDA election requires a T2054 filed with the CRA before or on the date of payment. This is an area where working with a CPA is essential, errors can be costly.
6. Tax-Efficient Charitable Giving
High-income Canadians who give to registered charities can structure those gifts to maximize both the social impact and the tax efficiency.
Donating Appreciated Securities
Instead of selling securities, paying capital gains tax, and donating the after-tax proceeds, you can donate the securities directly to a registered charity. The result:
The capital gains tax on the appreciated securities is eliminated (the inclusion rate drops to zero on donation)
You receive a donation receipt for the full fair market value of the securities
At a 53.53% marginal rate, the combined tax benefit, capital gains elimination plus donation credit can exceed 50 cents per dollar donated
This strategy is most powerful for long-held, highly appreciated stocks, mutual funds, or ETFs held in non-registered accounts.
Donor-Advised Funds (DAF)
A Donor-Advised Fund lets you make a large, lump-sum donation in a high-income year (generating a large immediate tax deduction), then distribute the funds to charitable recipients over multiple years on your own timeline. In Canada, several community foundations and financial institutions offer DAF programs.
This is particularly useful in years with outsized income events, a business sale, large bonus, or significant capital gain where you want the deduction now but may not have a specific charity in mind yet.
⚠️ AMT and Charitable Donations Under the 2024 AMT changes (effective for 2024 tax year), the donation tax credit is limited to 80% for AMT purposes (reduced from 100%). If you're subject to AMT, large charitable donations may not offset AMT as efficiently as regular income tax. A tax professional should model both scenarios before you give. |
7. Alternative Minimum Tax (AMT): What High Earners Must Know in 2025
The AMT was significantly overhauled for the 2024 tax year, and the changes directly target high-income earners who benefit from preferential tax treatment on capital gains, dividends, and charitable donations.
📌 Key AMT Changes: Effective 2024 Tax Year (Source: CRA / PwC Canada) AMT rate increased from 15% to 20.5% Basic AMT exemption raised from $40,000 to $173,205 (2024) / $177,882 (2025), indexed annually 100% of capital gains are included in AMT income (vs. 50% under regular rules) Only 80% of the charitable donation credit is permitted under AMT (down from 100%) Many non-refundable credits are limited to 50% for AMT purposes AMT can be carried forward 7 years and recovered against future regular tax Eligible dividends alone do not trigger AMT |
The AMT is a parallel tax calculation, you pay the higher of your regular tax or AMT. It's most likely to apply in years where you have significant capital gains (especially from eligible property like QSBC shares), large charitable donations, or substantial resource property deductions.
If you're planning a business sale, major asset disposition, or large charitable gift, model the AMT impact before the transaction closes. AMT paid in one year can be recovered over the following 7 years, but only to the extent your regular tax exceeds AMT in those years.
8. Estate Planning Considerations
High-income earners often have significant assets that will be subject to a deemed disposition at death, meaning capital gains tax on everything from non-registered investments to shares in a CCPC. Planning ahead can substantially reduce the eventual tax burden.
Spousal rollovers: Assets can transfer to a surviving spouse at cost, deferring the tax event until the second death.
Graduated Rate Estates (GRE): For the first 36 months after death, the estate can benefit from graduated tax rates rather than being taxed at the top rate on all income.
Trusts in wills: Testamentary trusts can provide income-splitting opportunities for surviving family members, particularly beneficial where there are significant non-registered assets.
Life insurance: Corporately-owned life insurance can be structured to fund tax liabilities at death, protect business assets, and flow insurance proceeds through the CDA tax-free.
Estate freeze: Allows a business owner to lock in the current value of their shares for tax purposes, transferring future growth to the next generation or a family trust at lower tax cost.
Estate and succession planning is highly fact-specific. The earlier the planning begins, the more options are available. For business owners, an annual review with a tax and estate lawyer is strongly recommended.
9. When to Hire a Tax Professional and What Kind
At the income levels where these strategies apply, the cost of professional advice is almost always recovered many times over. The question isn't whether to hire help, it's who.
Need | Best Resource |
Annual return with T4, investments, rental income | CPA (Chartered Professional Accountant) |
Corporate structure, CCPC optimization, salary/dividend split | CPA with small business or corporate tax specialization |
Prescribed rate loans, family trust setup | Tax lawyer + CPA working together |
IPP setup and actuarial calculations | Pension consultant + CPA |
Estate planning, will structure, business succession | Estate lawyer + tax specialist |
CRA audit, objections, appeals | Tax lawyer |
Engaging a CPA year-round, not just at tax time is the standard for high-income earners. Year-end planning meetings in October or November allow for proactive adjustments before December 31 deadlines.
Your High-Income Tax Planning Checklist
Verify your 2025 RRSP contribution room and make the maximum contribution by March 2, 2026 (or carry forward any unused room to apply in a future high-income year)
If incorporated: review your salary vs. dividend mix with your CPA before filing your corporate return
If you have a lower-income spouse: explore a prescribed rate loan at 3% for 2026, new loans can be established now
If your CCPC has capital gains: confirm your CDA balance and consider a capital dividend election
If you made large charitable donations: calculate your AMT exposure before filing
If you're over 40 and incorporated: ask your CPA about an IPP feasibility analysis
Book a year-end planning meeting with your advisor for fall 2026
