Section 2 — Income Splitting & Structuring
Sole Proprietor vs CCPC
Sole proprietor: all business income taxed at personal marginal rates. Simple, low compliance cost. Business losses offset personal income. No payroll remittances (except CPP).
Canadian-Controlled Private Corporation (CCPC): first $500,000 of active business income taxed at 9% federal (+ provincial, typically 2–4% = ~11–13% combined). Profits retained at corporate rate; extracted via salary or dividends. Integration principle: in theory, combined corporate + personal tax approximates personal tax alone. In practice, small gaps create planning opportunities.
When to incorporate: generally beneficial when annual business profit consistently exceeds ~$70,000–$80,000 and the owner can leave profits in the corporation. Below that, sole proprietorship is simpler and equally tax-efficient.
Salary vs Dividends (CCPC Owner-Manager)

Minimal (T5) |
Optimal mix: pay enough salary to maximise RRSP room ($33,810 limit for 2026 → requires ~$187,833 salary). If RRSP room is not needed, eligible dividends may produce slightly lower combined tax. Model annually — provincial rates create different break-even points.
TOSI (Tax on Split Income) — s 120.4
Income paid to family members (spouse, children) from a related business is subject to top marginal tax rate unless an exclusion applies:
- Excluded business: family member works ≥20 hours/week in the business
- Excluded shares: family member aged 25+, owns shares of a corporation where <90% of income is from services, 10%+ equity
- Reasonable return: compensation proportional to labour, capital, risk contributed
- Prescribed rate loans: lend funds to spouse at CRA prescribed rate (3% Q1 2026); spouse invests, attributes interest income back to lender, keeps excess returns

Accelerated Investment Incentive (AII)
For assets acquired after 20 November 2018 and available for use before 2028: enhanced first-year CCA. Effectively 1.5× the normal CCA rate in Year 1 (eliminates the half-year rule and adds a 50% bonus). Applies to most CCA classes.

CCPCs can immediately expense up to $1.5 million per year of eligible property (Classes 2–6, 8, 10, 12, etc.) acquired after 18 April 2021 and available for use before 2025 — verify ongoing extensions.
Section 5 — Loss Utilization
Non-Capital Losses
Carry back 3 years or carry forward 20 years (s 111(1)(a)). Business losses of a sole proprietor offset all personal income in the current year. Corporate losses stay in the corporation.
Capital Losses
Net capital losses carry back 3 years or forward indefinitely (s 111(1)(b)). Can only offset capital gains. At death, net capital losses can offset any income in the year of death and prior year.
Allowable Business Investment Losses (ABIL)
Loss on shares or debt of a small business corporation (s 38(c)). 50% of the loss is an ABIL, deductible against all income (not just capital gains). Excess becomes a non-capital loss.
Loss Planning
- Time capital gains and losses in the same year to offset
- Crystallise unrealised losses before year-end (beware superficial loss rule: 30-day rule, s 54)
- Consider transferring losing investments to a spouse at FMV to trigger loss (but attribution rules may apply)
Section 6 — Timing Strategies
| Strategy |
Detail |
| RRSP contribution by March 1 |
Contributions made by 1 March deductible in prior tax year. Carry forward deduction if in lower bracket now |
| Defer income |
Self-employed: delay invoicing past 31 December. Employees: defer bonuses to January |
| Accelerate deductions |
Prepay deductible expenses before 31 December. Purchase CCA-eligible assets before year-end |
| Charitable donations |
Carry forward donations up to 5 years. Consolidate to one spouse for higher credit rate (29%/33% on amounts >$200) |
| Capital gains deferral |
Hold assets >1 year (no discount, but defer realisation). Use CCPC to shelter passive income until extraction |
| LCGE crystallisation |
Trigger capital gain on QSBC shares up to $1,250,000 LCGE while still eligible. Useful before selling active business |
| Prescribed rate loan before rate increase |
Lock in lower CRA prescribed rate before quarterly adjustments |
Section 7 — GST/HST Optimization
| Topic |
Detail |
| Small supplier exemption |
Gross revenue ≤$30,000 in 4 consecutive quarters → no mandatory registration. But voluntary registration allows ITCs |
| Quick method |
Simplified GST remittance for businesses ≤$400,000 revenue. Remit a reduced percentage; keep the difference. Often advantageous for service businesses with few inputs |
| Input Tax Credits (ITCs) |
Claim GST/HST on business purchases. Documentation requirements: supplier name/BN, invoice date, total, GST amount |
| ITCs on vehicles |
Claim proportional to business use. Maintain logbook |
| Real property |
Self-supply rules on real property conversions. New residential property GST/HST rebate ($350,000–$450,000 threshold) |
| Place of supply |
GST vs HST depends on province of delivery. Optimise for lower-rate provinces where legitimately possible |
| Zero-rated exports |
Exports are zero-rated (0% GST) but ITCs on inputs still claimable |
Section 8 — CPP/EI & Social Security Optimization
CPP Contributions (2026)
- CPP1: 5.95% employee + 5.95% employer on pensionable earnings $3,500–$73,200 (max employee contribution ~$4,147)
- CPP2: 4% employee + 4% employer on earnings $73,200–$81,200 (second ceiling)
- Self-employed pay both halves (11.9% CPP1 + 8% CPP2)
- CCPC owner-manager paying dividends only: no CPP contributions → no CPP pension accrual. Trade-off: lower current cost vs lower retirement benefit
EI Premiums
- Employees: 1.64% on insurable earnings up to $65,700 (2026)
- Self-employed: can opt in for special benefits (maternity, sickness)
- CCPC dividends: no EI — but also no EI eligibility
Optimisation
- If owner-manager does not need CPP/EI benefits, dividends avoid these premiums (~$6,000+ annual saving)
- If building CPP entitlement, pay minimum salary to maximise CPP credits
- Balance against RRSP room generation (requires earned income)
Section 9 — Investment & Retirement
| Account |
2026 Limit |
Tax Treatment |
| RRSP |
$33,810 (or 18% of prior-year earned income) |
Contributions deductible; growth tax-deferred; withdrawals taxed as income |
| TFSA |
$7,000 (cumulative $109,000 since 2009) |
No deduction; growth and withdrawals tax-free |
| FHSA |
$8,000/year ($40,000 lifetime) |
Deductible like RRSP + tax-free withdrawal for first home (like TFSA). Best of both worlds |
| RESP |
$2,500/year to maximise CESG ($500 grant) |
No deduction; growth tax-deferred; grants from government; withdrawals taxed to student |
| RDSP |
Up to $200,000 lifetime |
Government grants/bonds up to $3,500/year. Must have DTC |
Strategy Framework
- FHSA first if qualifying first-time buyer — deductible AND tax-free withdrawal
- Employer RRSP match — capture free money before any other investment
- TFSA — fill annually, especially if in a lower bracket now (preserve RRSP room for higher-income years)
- RRSP — maximise in years with high marginal rate, plan to withdraw in lower-rate retirement
- RESP — trigger CESG grant ($500/child/year)
- Non-registered — use Canadian eligible dividends and capital gains (50% inclusion) for tax efficiency
Section 10 — Red Lines (GAAR & Scrutiny Triggers)
GAAR (s 245 ITA)
Applies when a transaction (i) results in a tax benefit, (ii) is an avoidance transaction (not primarily for bona fide non-tax purposes), and (iii) is abusive — misuses or frustrates the provisions of the Act. Consequence: tax benefit denied; potential penalties.
CRA Scrutiny Triggers
| Trigger |
Risk |
| TOSI-offending dividends to family members |
Top-rate tax + interest |
| Superficial losses (repurchase within 30 days) |
Loss denied (s 54) |
| Excessive salary to family members not working in business |
TOSI + reasonableness challenge |
| Personal expenses through corporation |
Shareholder benefit (s 15(1)) or deemed dividend (s 15(2)) |
| Automobile benefits |
Standby charge + operating benefit if personal use not properly reported |
| Non-arm's length transactions at non-FMV |
Transfer pricing rules (s 69, s 247) |
| Foreign reporting non-compliance |
T1135 (≥$100,000 foreign property). Penalties: $2,500/year late filing |
| Underground economy / unreported income |
CRA uses third-party data matching |
| RRSP over-contribution |
1% per month penalty tax on excess >$2,000 |
| Aggressive tax shelters |
CRA mandatory disclosure rules (s 237.3, 237.4) — expanded 2023 |
Absolute Prohibitions
- NEVER advise claiming personal expenses as business deductions
- NEVER advise hiding income or assets offshore without proper disclosure (T1135, T1134)
- NEVER advise ignoring TOSI rules when splitting income with family members
- NEVER advise repurchasing securities within 30 days to trigger a loss (superficial loss)
- NEVER advise backdating transactions or documentation

Section 12 — Cash Impact Examples
Example 1 — CCPC Salary vs Dividend Mix (Ontario, 2026)
Scenario: CCPC earns $200,000 active business income. Owner is sole shareholder.
All salary ($200,000): Corporate tax $0 (fully deductible). Personal tax ~$52,700 (Ontario combined). CPP: ~$8,300. RRSP room created: $33,810. Net after tax: ~$138,000.
All eligible dividends: Corporate tax at ~12.2% = $24,400. Remaining $175,600 as dividends. Personal tax on grossed-up dividends ~$25,200. No CPP. No RRSP room. Net after tax: ~$150,400. Saving: ~$12,400 but no CPP accrual or RRSP room.
Optimal blend: $100,000 salary + remainder as dividend. Balance of RRSP room, CPP accrual, and tax efficiency.
Example 2 — TFSA vs RRSP
Profile: 30-year-old earning $60,000 (20.5% federal bracket).
RRSP $7,000: tax refund ~$1,435 (20.5%). Invested for 30 years at 6% → $40,159 (pre-tax). Withdrawal at 14% bracket → $34,537 net. Advantage: $8,102 vs taxable.
TFSA $7,000: no refund. Same growth → $40,159. Withdrawal tax-free = $40,159 net. Advantage: $5,622 more than RRSP if future bracket is similar.
Example 3 — LCGE on Business Sale
Owner sells qualifying small business corporation shares. Capital gain: $1,000,000. LCGE shelters the full gain (within $1,250,000 lifetime limit). Tax at 50% inclusion × 33% rate = $165,000 avoided. Cash saving: $165,000.

Owner is sole shareholder.265266**All salary ($200,000):** Corporate tax $0 (fully deductible). Personal tax ~$52,700 (Ontario combined). CPP: ~$8,300. RRSP room created: $33,810. **Net after tax: ~$138,000.**267268**All eligible dividends:** Corporate tax at ~12.2% = $24,400. Remaining $175,600 as dividends. Personal tax on grossed-up dividends ~$25,200. No CPP. No RRSP room. **Net after tax: ~$150,400. Saving: ~$12,400** but no CPP accrual or RRSP room.269270**Optimal blend:** $100,000 salary + remainder as dividend. Balance of RRSP room, CPP accrual, and tax efficiency.271272### Example 2 — TFSA vs RRSP273274**Profile:** 30-year-old earning $60,000 (20.5% federal bracket).275276**RRSP $7,000:** tax refund ~$1,435 (20.5%). Invested for 30 years at 6% → $40,159 (pre-tax). Withdrawal at 14% bracket → $34,537 net. **Advantage: $8,102 vs taxable.**277278**TFSA $7,000:** no refund. Same growth → $40,159. Withdrawal tax-free = $40,159 net. **Advantage: $5,622 more than RRSP if future bracket is similar.**279280### Example 3 — LCGE on Business Sale281282Owner sells qualifying small business corporation shares. Capital gain: $1,000,000. LCGE shelters the full gain (within $1,250,000 lifetime limit). Tax at 50% inclusion × 33% rate = $165,000 avoided. **Cash saving: $165,000.**283284---285286## Disclaimer287288This skill and its outputs are provided for informational and computational purposes only and do not constitute tax, legal, or financial advice.
