Your numbers
Business revenue minus deductible expenses (your T2125 net income).
Employment, rental, or other taxable income. CPP is not applied to this.
Corporate net income before deducting your own salary.
Deducted from corporate income; taxed personally. Employer CPP is also deducted corporately.
Taxed at the CCPC investment rate (not the small-business rate). Over $50,000, this also grinds the SBD limit — $5 of limit lost per $1 over.

What this estimate includes — and what it doesn't
- 2026 federal and provincial brackets and basic personal amounts, verified against CRA and Revenu Québec published rates (including the 14% federal bottom rate and BC's new 5.60% bottom rate).
- CPP/QPP and CPP2 at 2026 ceilings (YMPE $74,600, YAMPE $85,000), with the correct split between the credit and deduction portions.
- Ontario surtax and Ontario Health Premium; Quebec's 16.5% federal abatement.
- Federal BPA clawback between $181,440 and $258,482 (Yukon mirrors it).
- Passive investment income inside the corporation is taxed at the CCPC investment rate (38.67% federal + the provincial general rate), not the small-business rate. A portion of the federal tax is refundable later when you pay dividends (NERDTOH) — that refund is not netted here.
- Not modelled: other personal credits (spousal, medical, donations), provincial low-income reductions, EI (self-employed and >40% shareholders are generally exempt), Quebec's health services fund contribution, AMT, Part IV tax on portfolio dividends, and the taxable-capital SBD grind. Dividends are planned in our Dividend vs. Salary Calculator.
