| 17 | |
| 18 | ## Section 1 — Quick Reference |
| 19 | |
| 20 | | Field | Value | |
| 21 | |---|---| |
| 22 | | Country | Canada | |
| 23 | | Currency | CAD | |
| 24 | | Tax year | Calendar year (1 January – 31 December) | |
| 25 | | Primary legislation | Income Tax Act (R.S.C., 1985, c. 1 (5th Supp.)) | |
| 26 | | Anti-avoidance | GAAR (s 245 ITA); TOSI (s 120.4) | |
| 27 | | Tax authority | Canada Revenue Agency (CRA) | |
| 28 | | Filing deadline | 30 April (employees); 15 June (self-employed, but tax owing still due 30 April) | |
| 29 | | Individual top federal rate | 33% (on income >$253,414) | |
| 30 | | Combined top rate (varies by province) | ~50–54% | |
| 31 | | CCPC small business rate (federal) | 9% on first $500,000 active business income | |
| 32 | | General corporate rate (federal) | 15% | |
| 33 | | Capital gains inclusion rate | 50% (66.7% increase was cancelled) | |
| 34 | | GST rate | 5% (HST varies by province: 13%–15%) | |
| 35 | |
| 36 | ### Federal Tax Brackets (2026) |
| 37 | |
| 38 | | Taxable Income (CAD) | Rate | |
| 39 | |---|---| |
| 40 | | 0 – 57,375 | 14% | |
| 41 | | 57,376 – 114,750 | 20.5% | |
| 42 | | 114,751 – 158,468 | 26% | |
| 43 | | 158,469 – 220,000 | 29% | |
| 44 | | 220,001 – 253,414 | 33% | |
| 45 | |
| 46 | Note: The lowest bracket rate was reduced to 14% (from 15%) effective 2026 via Bill C-4. |
| 47 | |
| 48 | --- |
| 49 | |
| 50 | ## Section 2 — Income Splitting & Structuring |
| 51 | |
| 52 | ### Sole Proprietor vs CCPC |
| 53 | |
| 54 | **Sole proprietor:** all business income taxed at personal marginal rates. Simple, low compliance cost. Business losses offset personal income. No payroll remittances (except CPP). |
| 55 | |
| 56 | **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. |
| 57 | |
| 58 | **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. |
| 59 | |
| 60 | ### Salary vs Dividends (CCPC Owner-Manager) |
| 61 | |
| 62 | | Factor | Salary | Dividends | |
| 63 | |---|---|---| |
| 64 | | Corporate deduction | Yes | No | |
| 65 | | CPP contributions | Yes (creates room) | No | |
| 66 | | RRSP room created | Yes (18% of earned income) | No | |
| 67 | | Childcare expense room | Yes | No | |
| 68 | | Personal tax treatment | Marginal rates | Gross-up + dividend tax credit | |
| 69 | | Payroll admin | Required (T4, remittances) | Minimal (T5) | |
| 70 | |
| 71 | **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. |
| 72 | |
| 73 | ### TOSI (Tax on Split Income) — s 120.4 |
| 74 | |
| 75 | Income paid to family members (spouse, children) from a related business is subject to top marginal tax rate unless an exclusion applies: |
| 76 | - **Excluded business:** family member works ≥20 hours/week in the business |
| 77 | - **Excluded shares:** family member aged 25+, owns shares of a corporation where <90% of income is from services, 10%+ equity |
| 78 | - **Reasonable return:** compensation proportional to labour, capital, risk contributed |
| 79 | - **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 |
| 80 | |
| 81 | --- |
| 82 | |
| 83 | ## Section 3 — Deductions Most People Miss |
| 84 | |
| 85 | | Deduction | Provision | Notes | |
| 86 | |---|---|---| |
| 87 | | Home office expenses | s 8(1)(f), 8(1)(i), 18(12) | Employees: T2200 required. Self-employed: proportion of rent/mortgage interest, utilities, insurance, property tax | |
| 88 | | Moving expenses | s 62 | Must move ≥40 km closer to new work/business location. Deduct against income at new location | |
| 89 | | Carrying charges | s 20(1)(c) | Interest on money borrowed to earn investment income. Includes investment counsel fees | |
| 90 | | Medical expenses | s 118.2 | Tax credit at 15% federal on expenses >3% of net income or $2,759 (lesser). Include premiums, dental, prescriptions, travel for treatment | |
| 91 | | Disability tax credit | s 118.3 | $9,872 federal credit (2026). Transferable to supporting person. Unlocks RDSP eligibility | |
| 92 | | Northern residents deduction | s 110.7 | Residency deduction + travel benefits for prescribed zones | |
| 93 | | Capital cost allowance (CCA) on rental property | s 20(1)(a), Sch II | Class 1 (4%), Class 8 (20%). Accelerated Investment Incentive (triple declining balance in year 1) | |
| 94 | | Apprentice mechanic tools | s 8(1)(s) | Cost exceeding $1,368 (2026 indexed) | |
| 95 | | Union/professional dues | s 8(1)(i) | Full deduction | |
| 96 | | Child care expenses | s 63 | $8,000/child under 7; $5,000/child 7–16. Must be claimed by lower-income spouse (exceptions apply) | |
| 97 | |
| 98 | --- |
| 99 | |
| 100 | ## Section 4 — Capital Allowances Optimization |
| 101 | |
| 102 | ### Accelerated Investment Incentive (AII) |
| 103 | |
| 104 | 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. |
| 105 | |
| 106 | ### Key CCA Classes |
| 107 | |
| 108 | | Class | Rate | Assets | |
| 109 | |---|---|---| |
| 110 | | 1 | 4% | Buildings acquired after 1987 | |
| 111 | | 8 | 20% | Furniture, fixtures, equipment, machinery | |
| 112 | | 10 | 30% | Motor vehicles (cost limit $37,000 + tax for passenger vehicles) | |
| 113 | | 10.1 | 30% | Passenger vehicles over cost limit (separate class per vehicle) | |
| 114 | | 12 | 100% | Computer software, tools <$500 | |
| 115 | | 50 | 55% | Computer hardware and systems software | |
| 116 | | 54 | 0% (expensed) | Zero-emission vehicles up to $61,000 + tax | |
| 117 | |
| 118 | ### Immediate Expensing (CCPCs) |
| 119 | |
| 120 | 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. |
| 121 | |
| 122 | --- |
| 123 | |
| 124 | ## Section 5 — Loss Utilization |
| 125 | |
| 126 | ### Non-Capital Losses |
| 127 | |
| 128 | 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. |
| 129 | |
| 130 | ### Capital Losses |
| 131 | |
| 132 | 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. |
| 133 | |
| 134 | ### Allowable Business Investment Losses (ABIL) |
| 135 | |
| 136 | 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. |
| 137 | |
| 138 | ### Loss Planning |
| 139 | |
| 140 | - Time capital gains and losses in the same year to offset |
| 141 | - Crystallise unrealised losses before year-end (beware superficial loss rule: 30-day rule, s 54) |
| 142 | - Consider transferring losing investments to a spouse at FMV to trigger loss (but attribution rules may apply) |
| 143 | |
| 144 | --- |
| 145 | |
| 146 | ## Section 6 — Timing Strategies |
| 147 | |
| 148 | | Strategy | Detail | |
| 149 | |---|---| |
| 150 | | RRSP contribution by March 1 | Contributions made by 1 March deductible in prior tax year. Carry forward deduction if in lower bracket now | |
| 151 | | Defer income | Self-employed: delay invoicing past 31 December. Employees: defer bonuses to January | |
| 152 | | Accelerate deductions | Prepay deductible expenses before 31 December. Purchase CCA-eligible assets before year-end | |
| 153 | | Charitable donations | Carry forward donations up to 5 years. Consolidate to one spouse for higher credit rate (29%/33% on amounts >$200) | |
| 154 | | Capital gains deferral | Hold assets >1 year (no discount, but defer realisation). Use CCPC to shelter passive income until extraction | |
| 155 | | LCGE crystallisation | Trigger capital gain on QSBC shares up to $1,250,000 LCGE while still eligible. Useful before selling active business | |
| 156 | | Prescribed rate loan before rate increase | Lock in lower CRA prescribed rate before quarterly adjustments | |
| 157 | |
| 158 | --- |
| 159 | |
| 160 | ## Section 7 — GST/HST Optimization |
| 161 | |
| 162 | | Topic | Detail | |
| 163 | |---|---| |
| 164 | | Small supplier exemption | Gross revenue ≤$30,000 in 4 consecutive quarters → no mandatory registration. But voluntary registration allows ITCs | |
| 165 | | 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 | |
| 166 | | Input Tax Credits (ITCs) | Claim GST/HST on business purchases. Documentation requirements: supplier name/BN, invoice date, total, GST amount | |
| 167 | | ITCs on vehicles | Claim proportional to business use. Maintain logbook | |
| 168 | | Real property | Self-supply rules on real property conversions. New residential property GST/HST rebate ($350,000–$450,000 threshold) | |
| 169 | | Place of supply | GST vs HST depends on province of delivery. Optimise for lower-rate provinces where legitimately possible | |
| 170 | | Zero-rated exports | Exports are zero-rated (0% GST) but ITCs on inputs still claimable | |
| 171 | |
| 172 | --- |
| 173 | |
| 174 | ## Section 8 — CPP/EI & Social Security Optimization |
| 175 | |
| 176 | ### CPP Contributions (2026) |
| 177 | |
| 178 | - **CPP1:** 5.95% employee + 5.95% employer on pensionable earnings $3,500–$73,200 (max employee contribution ~$4,147) |
| 179 | - **CPP2:** 4% employee + 4% employer on earnings $73,200–$81,200 (second ceiling) |
| 180 | - Self-employed pay both halves (11.9% CPP1 + 8% CPP2) |
| 181 | - CCPC owner-manager paying dividends only: no CPP contributions → no CPP pension accrual. Trade-off: lower current cost vs lower retirement benefit |
| 182 | |
| 183 | ### EI Premiums |
| 184 | |
| 185 | - Employees: 1.64% on insurable earnings up to $65,700 (2026) |
| 186 | - Self-employed: can opt in for special benefits (maternity, sickness) |
| 187 | - CCPC dividends: no EI — but also no EI eligibility |
| 188 | |
| 189 | ### Optimisation |
| 190 | |
| 191 | - If owner-manager does not need CPP/EI benefits, dividends avoid these premiums (~$6,000+ annual saving) |
| 192 | - If building CPP entitlement, pay minimum salary to maximise CPP credits |
| 193 | - Balance against RRSP room generation (requires earned income) |
| 194 | |
| 195 | --- |
| 196 | |
| 197 | ## Section 9 — Investment & Retirement |
| 198 | |
| 199 | | Account | 2026 Limit | Tax Treatment | |
| 200 | |---|---|---| |
| 201 | | RRSP | $33,810 (or 18% of prior-year earned income) | Contributions deductible; growth tax-deferred; withdrawals taxed as income | |
| 202 | | TFSA | $7,000 (cumulative $109,000 since 2009) | No deduction; growth and withdrawals tax-free | |
| 203 | | FHSA | $8,000/year ($40,000 lifetime) | Deductible like RRSP + tax-free withdrawal for first home (like TFSA). Best of both worlds | |
| 204 | | RESP | $2,500/year to maximise CESG ($500 grant) | No deduction; growth tax-deferred; grants from government; withdrawals taxed to student | |
| 205 | | RDSP | Up to $200,000 lifetime | Government grants/bonds up to $3,500/year. Must have DTC | |
| 206 | |
| 207 | ### Strategy Framework |
| 208 | |
| 209 | 1. **FHSA first** if qualifying first-time buyer — deductible AND tax-free withdrawal |
| 210 | 2. **Employer RRSP match** — capture free money before any other investment |
| 211 | 3. **TFSA** — fill annually, especially if in a lower bracket now (preserve RRSP room for higher-income years) |
| 212 | 4. **RRSP** — maximise in years with high marginal rate, plan to withdraw in lower-rate retirement |
| 213 | 5. **RESP** — trigger CESG grant ($500/child/year) |
| 214 | 6. **Non-registered** — use Canadian eligible dividends and capital gains (50% inclusion) for tax efficiency |
| 215 | |
| 216 | --- |
| 217 | |
| 218 | ## Section 10 — Red Lines (GAAR & Scrutiny Triggers) |
| 219 | |
| 220 | ### GAAR (s 245 ITA) |
| 221 | |
| 222 | 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. |
| 223 | |
| 224 | ### CRA Scrutiny Triggers |
| 225 | |
| 226 | | Trigger | Risk | |
| 227 | |---|---| |
| 228 | | TOSI-offending dividends to family members | Top-rate tax + interest | |
| 229 | | Superficial losses (repurchase within 30 days) | Loss denied (s 54) | |
| 230 | | Excessive salary to family members not working in business | TOSI + reasonableness challenge | |
| 231 | | Personal expenses through corporation | Shareholder benefit (s 15(1)) or deemed dividend (s 15(2)) | |
| 232 | | Automobile benefits | Standby charge + operating benefit if personal use not properly reported | |
| 233 | | Non-arm's length transactions at non-FMV | Transfer pricing rules (s 69, s 247) | |
| 234 | | Foreign reporting non-compliance | T1135 (≥$100,000 foreign property). Penalties: $2,500/year late filing | |
| 235 | | Underground economy / unreported income | CRA uses third-party data matching | |
| 236 | | RRSP over-contribution | 1% per month penalty tax on excess >$2,000 | |
| 237 | | Aggressive tax shelters | CRA mandatory disclosure rules (s 237.3, 237.4) — expanded 2023 | |
| 238 | |
| 239 | ### Absolute Prohibitions |
| 240 | |
| 241 | - NEVER advise claiming personal expenses as business deductions |
| 242 | - NEVER advise hiding income or assets offshore without proper disclosure (T1135, T1134) |
| 243 | - NEVER advise ignoring TOSI rules when splitting income with family members |
| 244 | - NEVER advise repurchasing securities within 30 days to trigger a loss (superficial loss) |
| 245 | - NEVER advise backdating transactions or documentation |
| 246 | |
| 247 | --- |
| 248 | |
| 249 | ## Section 11 — Annual Tax Planning Calendar |
| 250 | |
| 251 | | When | Action | |
| 252 | |---|---| |
| 253 | | January | New TFSA room available ($7,000). Review prescribed rate for spousal loans. Ensure FHSA contribution on track | |
| 254 | | February | Final month for prior-year RRSP contribution (deadline 1 March). Model optimal RRSP vs TFSA split | |
| 255 | | March 1 | RRSP contribution deadline for prior-year deduction | |
| 256 | | April 30 | Personal tax return filing deadline. Tax balance owing due. CPP/EI self-employed remittance due | |
| 257 | | June 15 | Filing deadline for self-employed (but tax was due April 30) | |
| 258 | | June 30 | CCPC fiscal year-end (if elected). Review salary vs dividend mix | |
| 259 | | September | Model year-end tax position. Review quarterly instalment obligations | |
| 260 | | October–November | Execute capital gains/loss harvesting. Make charitable donations. Prepay deductible expenses | |
| 261 | | December 31 | **Critical date.** TFSA contributions. RESP contributions to trigger CESG. SRS/RRSP contributions for current year. Year-end trust distributions. Ensure T5013 / T3 slips timing. Pay salary/bonus before year-end for earned income | |
| 262 | |
| 263 | --- |
| 264 | |
| 265 | ## Section 12 — Cash Impact Examples |
| 266 | |
| 267 | ### Example 1 — CCPC Salary vs Dividend Mix (Ontario, 2026) |
| 268 | |
| 269 | **Scenario:** CCPC earns $200,000 active business income. Owner is sole shareholder. |
| 270 | |
| 271 | **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.** |
| 272 | |
| 273 | **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. |
| 274 | |
| 275 | **Optimal blend:** $100,000 salary + remainder as dividend. Balance of RRSP room, CPP accrual, and tax efficiency. |
| 276 | |
| 277 | ### Example 2 — TFSA vs RRSP |
| 278 | |
| 279 | **Profile:** 30-year-old earning $60,000 (20.5% federal bracket). |
| 280 | |
| 281 | **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.** |
| 282 | |
| 283 | **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.** |
| 284 | |
| 285 | ### Example 3 — LCGE on Business Sale |
| 286 | |
| 287 | 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.** |
