The 2026 Canadian corporate tax rate, by province.
There isn't one corporate tax rate in Canada — there are four, and which one applies depends on the type of income, the size of the company, and the province.
For an incorporated Canadian business owner, the corporate tax rate is the single most important number on the balance sheet. It determines how much retained earnings actually compound at, the spread between corporate and personal taxation that drives every salary-vs-dividend decision, and the cost of keeping investment capital in the company versus moving it into a tax-exempt structure.
This guide consolidates the 2026 rates federally and across every province for the four income categories that matter — general active income, small-business-deduction (SBD) active income, manufacturing & processing (M&P), and passive investment income — and walks through the planning implications.
Federal corporate rates — 2026
The federal corporate tax begins as a flat 38% but is reduced by two structural credits:
| Step | Adjustment | Resulting rate |
|---|---|---|
| Statutory federal rate | 38% | — |
| Federal abatement (provincial room) | −10% | 28% |
| General rate reduction | −13% | 15% (general) |
| Small business deduction | −9% (CCPC SBD only) | 9% (SBD) |
SBD applies on the first $500,000 of CCPC active business income, subject to the AAII grind and taxable-capital phase-out.
Combined corporate rates by province (2026)
| Province | SBD combined | General combined | M&P combined |
|---|---|---|---|
| British Columbia | 11.0% | 27.0% | 27.0% |
| Alberta | 11.0% | 23.0% | 23.0% |
| Saskatchewan | 10.0% | 27.0% | 25.0% |
| Manitoba | 9.0% | 27.0% | 27.0% |
| Ontario | 12.2% | 26.5% | 25.0% |
| Quebec | 12.2% | 26.5% | 26.5% |
| New Brunswick | 11.5% | 29.0% | 29.0% |
| Nova Scotia | 11.5% | 29.0% | 29.0% |
| PEI | 10.0% | 31.0% | 31.0% |
| Newfoundland & Labrador | 11.5% | 30.0% | 30.0% |
| Yukon | 9.0% | 27.0% | 17.5% |
| NWT | 11.0% | 26.5% | 26.5% |
| Nunavut | 12.0% | 27.0% | 27.0% |
Combined federal + provincial. Provincial budgets can adjust mid-year; verify against current finance department releases before relying on a number for filing.
The headline number — Alberta at 23%, BC and Ontario at ~27% general — masks a wider underlying spread once passive-income and SBD-claw-back rules are applied. The next two sections work through both.
The small business deduction and its grinds
The SBD is available only to Canadian-controlled private corporations (CCPCs) and is subject to two phase-out rules that materially shrink its availability for a successful operating company:
The taxable-capital grind
The $500,000 limit is reduced on a straight-line basis when taxable capital employed in Canada (across the associated group) exceeds $10 million, and is fully eliminated at $50 million. This was relaxed in 2022 — the upper threshold rose from $15 million to $50 million — but most growing operating companies still see partial grinds well before they cross the line.
The passive-income (AAII) grind
The $500,000 limit is reduced by $5 for every $1 of Adjusted Aggregate Investment Income above $50,000 in the associated CCPC group, and is fully eliminated at $150,000 of AAII. This is the binding constraint for HNW operating companies that have accumulated investment portfolios.
| Passive income (AAII) | SBD limit | % of $500K available |
|---|---|---|
| ≤ $50,000 | $500,000 | 100% |
| $75,000 | $375,000 | 75% |
| $100,000 | $250,000 | 50% |
| $125,000 | $125,000 | 25% |
| ≥ $150,000 | $0 | 0% |
The structural cost. Every additional dollar of taxable interest income above $50,000 of AAII costs the operating group up to $50 of lost SBD eligibility. Above the $150K threshold, every dollar of active income that used to be taxed at ~12% is suddenly taxed at ~27% — a structural drag that compounds for as long as it persists.
Passive investment income — ~50% effective rate
Investment income earned inside a CCPC — interest, foreign dividends, taxable capital gains — is taxed at a high integrated rate of approximately 50.17% federally combined with the provincial passive rate, putting the total in the 50% – 55% range across provinces. The mechanism:
| Component | Rate | Note |
|---|---|---|
| Federal Part I tax (general) | 38.67% | Includes the additional refundable tax (ART) on investment income. |
| Provincial passive rate | ~11.5% | Province-dependent; adds to roughly 50% combined. |
| Refundable portion (RDTOH) | 30.67% of investment income | Tracked in non-eligible RDTOH, refundable when taxable dividends are paid. |
Eligible-RDTOH applies to portfolio dividends from public-company shares. For non-CCPCs the rates and refundability differ.
The RDTOH refund recovers about half of the upfront tax, but only when capital is paid out as a taxable dividend — which restarts the personal tax stack. Net of refunds, the integrated end-to-end tax on capital that earns a year of investment return inside a CCPC and is then distributed personally is materially worse than the same dollar earned personally to begin with.
This is the structural reason most HNW corporate balance sheets that exceed $1M of investable capital eventually shift toward tax-exempt structures.
Integration & the personal-corporate spread
"Integration" is the principle that a dollar earned through a corporation and then distributed should produce roughly the same total tax as if it had been earned personally. The system aims for it; in practice it under- and over-shoots by a few points depending on the income type and province.
The two spreads that drive every owner-manager planning decision:
| Spread | Approx. value (Ontario, 2026) | What it drives |
|---|---|---|
| Top personal rate − SBD corporate rate | 53.5% − 12.2% = 41.3% | Deferral benefit of retaining earnings in the corp. |
| Top personal rate − general corporate rate | 53.5% − 26.5% = 27.0% | Deferral benefit above the SBD limit. |
| Personal eligible div rate − corp general rate | 39.34% − 26.5% | Integration mismatch on payout. |
Approximate. Integration is exact in some provinces and not others; consult your CPA for your specific facts.
The deferral spread — typically 25 – 41 percentage points — is the single largest source of compounding for an incorporated owner. It is also the entire economic case for keeping retained earnings in the corp rather than bonusing them out and investing personally.
What the rates imply for planning
Salary vs. dividend mix
The optimal mix depends on the spread between SBD-rate retained earnings and the personal eligible-vs-non-eligible dividend rates. Use our salary-vs-dividends calculator to model 2026 outcomes by province.
Move passive capital out of the CCPC
Once AAII is approaching $50,000, every additional dollar of taxable investment income costs disproportionately. Tax-exempt vehicles that don't generate AAII — corporate-owned permanent life insurance, an IPP, an RCA, or an IRP — preserve the SBD and remove the 50% drag.
Use the IFA to deploy retained capital
An Immediate Financing Arrangement deposits capital into a permanent insurance policy and borrows it back to redeploy into the operating business — preserving liquidity while shifting the underlying capital out of the punitive passive-income environment.
Plan the exit around the corporate rate
An eventual sale typically combines the family trust + estate freeze + LCGE stack. The LCGE shelters up to ~$1.25M per qualifying shareholder; the corporate tax rate applies to everything above. See the 2026 Canadian tax tables for the full reference set.
FAQ
The federal general rate is 15%. Combined federal-plus-provincial general rates in 2026 range from approximately 23% in Alberta to roughly 31% in PEI. CCPC active business income up to the $500,000 SBD limit is taxed at the much lower combined small-business rate of approximately 9% to 12.2% depending on province.
9% federally on the first $500,000 of active business income for a Canadian-controlled private corporation. Combined federal + provincial small business rates in 2026 range from approximately 9% (Manitoba) to 12.2% (Ontario, Quebec).
At an integrated rate of approximately 50% – 55% depending on province. A portion (about 30.67% of investment income) is refundable as RDTOH when the corporation pays a taxable dividend. Net of refunds, the end-to-end tax on corporate-earned-and-distributed investment income is typically worse than personal taxation of the same income.
The $500,000 SBD limit is reduced by $5 for every $1 of Adjusted Aggregate Investment Income (AAII) above $50,000 in the associated CCPC group, and is fully eliminated at $150,000 of AAII. Separately, the SBD is also reduced when taxable capital employed in Canada (across the associated group) exceeds $10 million, fully phased out at $50 million.
By moving capital out of the punitive passive-income category and into vehicles that don't generate AAII: corporate-owned permanent life insurance, an Individual Pension Plan, a Retirement Compensation Arrangement, or an Insured Retirement Program. Each preserves the SBD and removes the year-by-year 50% drag on investment compounding.
No major federal change is in force for 2026. The federal general rate remains 15% and the SBD remains 9%. Provincial rates are subject to in-year budget changes — verify against the current provincial finance department release before relying on a specific number for filing.
