Tax Changes Coming in 2027:
What to Prepare For
Canadian tax law is evolving rapidly — and the decisions business owners make in 2026 will significantly affect their tax position under the rules taking shape for 2027 and beyond. From the ongoing capital gains inclusion rate debate and expanded Clean Economy Investment Tax Credits, to the global corporate minimum tax, enhanced CRA data matching, and new digital economy reporting obligations, the 2027 tax landscape requires proactive planning. This guide covers every major Canadian tax change on the horizon, what it means for your business, and the specific actions to take now while planning windows remain open.
1. Why 2026 Is the Critical Year to Plan for 2027
Tax planning is most valuable before the year in question — not during it, and certainly not after. The tax decisions that reduce a business owner’s 2027 tax bill are made in 2026: structuring decisions, capital expenditure timing, disposition timing, salary and dividend optimization, and RRSP and retirement planning all have 2026 action points that affect 2027 outcomes.
The 2027 tax environment in Canada is shaped by a convergence of proposed legislative changes, regulatory expansions, and economic pressures that represent the most significant potential shift in Canadian business taxation in a decade. Some changes are law; some are proposed; some are the subject of ongoing political debate. The appropriate response to all of them is the same: understand the change, model its impact on your specific situation, and take the planning actions available to you while time remains.

2. Capital Gains Inclusion Rate — The Biggest Risk for Business Owners
The proposed change: the federal government proposed increasing the capital gains inclusion rate from 1/2 (50%) to 2/3 (66.7%) for corporations and trusts — and for individuals on capital gains above $250,000 in a calendar year. As of May 2026, the legislative status of this change remains in political flux — it has been proposed but the exact implementation timeline should be confirmed with a CPA as legislation evolves.
Why it matters for incorporated business owners: for a business owner selling shares of their company with a $2M capital gain above the Lifetime Capital Gains Exemption (LCGE): at 1/2 inclusion = $1M included in taxable income. At 2/3 inclusion = $1.33M included. The additional $330,000 of inclusion at the corporate or personal tax rate creates a material additional tax cost.
LCGE protection becomes more critical: the LCGE (approximately $1.25M for Qualified Small Business Corporation shares in 2026) shelters capital gains from this increased rate — making QSBC compliance monitoring more important than ever. One year of non-compliance (passive assets test, 90% active business test, 24-month holding period) can disqualify the exemption.
3. Clean Economy Investment Tax Credits — The Largest Opportunity
Why 2026–2027 is the critical window: Canada’s suite of Clean Economy Investment Tax Credits are among the most significant capital cost incentives in the country’s history. By 2027, these credits are fully operational — and the labour and Indigenous participation requirements that determine the credit rate are fully enforced. Businesses that invest in qualifying clean technology, manufacturing, and energy assets receive refundable credits — cash from CRA even if the business has no tax payable.
4. Corporate Alternative Minimum Tax & Global Minimum Tax
Individual AMT changes (in effect for 2024+): the federal government significantly expanded the Alternative Minimum Tax for individuals, raising the AMT rate from 15% to 20.5% and broadening the base to include 100% of capital gains (vs. 80% previously), limited inclusion of charitable donation credits, and other adjustments. This primarily affects high-income individuals with large capital gains, significant stock option income, or substantial resource sector investments. The AMT is a “shadow tax” — if the AMT calculation exceeds regular tax, the individual pays the higher amount. AMT paid can be recovered in future years when regular tax exceeds AMT.
Global Minimum Tax — Pillar Two (in effect for fiscal years beginning 2024): a 15% global minimum tax applies to large multinational groups with consolidated revenues above EUR 750M. Canada implemented the Qualified Domestic Minimum Top-Up Tax (QDMTT) to capture minimum tax on Canadian profits of qualifying groups before other countries can. This primarily affects large multinationals with complex international structures — not most Canadian SMEs. However, subsidiaries of large foreign parents operating in Canada may be affected.
5. Digital Services Tax & Gig Economy Reporting
Digital Services Tax (DST): Canada’s 3% tax on large digital companies’ Canadian revenues from specific digital services was implemented as part of broader international digital economy taxation measures. The DST primarily targets companies with global revenue above EUR 750M and Canadian revenue above CAD $20M from covered services — primarily large US technology companies. Direct impact on Canadian SMEs is limited, but indirect effects (advertising cost changes, platform fee changes) may be felt.
Gig Economy & Platform Reporting (OECD DAC7 / CRA equivalent): the more impactful change for Canadian small businesses and individuals is CRA’s implementation of platform reporting requirements modeled on the OECD’s DAC7 framework. Digital platforms (Airbnb, Vrbo, eBay, Etsy, Uber, DoorDash, Amazon Marketplace, TaskRabbit, and similar) are increasingly required to collect and report seller and service provider income information to CRA. The implication: CRA now has direct access to income data from gig economy platforms that was previously unreported by many participants. Failing to report this income on T1 or T2 returns is increasingly detectable — and CRA is actively matching platform reports to filed returns.
6. Expanded CRA Data Matching & Enforcement
What CRA now receives automatically: CRA’s data matching capabilities have expanded dramatically in recent years and continue growing. By 2027, CRA has data-sharing agreements and mandatory reporting relationships that include:
| Data Source | Information CRA Receives | Risk for Non-Reporters |
|---|---|---|
| Digital platforms (Airbnb, eBay, Etsy, Uber, etc.) | Annual gross income earned by Canadian sellers and service providers on the platform; SIN or BN if collected | High — CRA matches platform reports to T1/T2 returns; unexplained income gaps generate automatic review letters |
| Cryptocurrency exchanges | Canadian resident customer account information; transaction volumes (for larger accounts); KYC data from Canadian-registered exchanges | High — crypto dispositions are taxable; unreported gains from Bitcoin/Ethereum/alt-coin sales are a growing audit target |
| Real estate land registries | Buyer and seller identity on all real property transactions; purchase price; mortgage information | High — property flips not reported as business income; foreign buyers not reporting Canadian real estate gains; land registry cross-referencing is active |
| Foreign financial assets (T1135) | Foreign financial assets above $100,000; offshore accounts; foreign investment income; automatic exchange under CRS (Common Reporting Standard) | Very high — CRS produces automatic information from 100+ participating countries to CRA; offshore accounts that were previously invisible are now reported |
| Payment processors (VISA, MasterCard, PayPal) | Merchant payment volumes for Canadian businesses processing above threshold levels | Medium-High — merchant payment volumes used to cross-reference against reported business income |
7. CPP Enhancements & Payroll Changes
CPP2 — the second-tier enhancement: CPP2 is a second tier of Canada Pension Plan contributions that applies on earnings between the Year’s Maximum Pensionable Earnings (YMPE) and the Year’s Additional Maximum Pensionable Earnings (YAMPE). Both the employee and employer contribute at 4% on the earnings in this band. As the YMPE and YAMPE increase annually (indexed to wages), both employees and employers face growing CPP contribution obligations. For employers with higher-paid staff (engineers, executives, professionals): the employer’s CPP2 matching contribution is an increasing payroll cost that must be factored into 2027 compensation modeling.
EI premium rate adjustments: EI premium rates are set annually by the EI Commission based on actuarial projections of the EI fund balance. Rates fluctuate year-to-year. For payroll planning, always use CRA’s published rates for the current year — never assume prior-year rates apply.
8. Impact by Business Type — Who Is Most Affected
| Business / Taxpayer Type | Most Relevant 2027 Changes | Priority Actions |
|---|---|---|
| Incorporated business owner planning to sell in 2–5 years | Capital gains inclusion rate change (highest impact); LCGE eligibility; AMT for large gains | QSBC compliance review; model tax cost under current vs. proposed rates; consider whether to accelerate or delay sale timeline; estate freeze assessment |
| Real estate investor / landlord | Capital gains inclusion rate (on property dispositions); expanded CRA land registry data matching; short-term rental platform reporting | Review tax position on rental portfolio; model any planned dispositions under both rates; ensure all rental income is correctly reported; confirm GST/HST on new construction |
| Clean energy / renewable developer | Clean Technology ITC (30%); Clean Electricity ITC (15–20%); CCUS ITC; labour requirements (fully enforced by 2027) | Identify all qualifying capital investments; confirm ITC eligibility; implement prevailing wage and apprenticeship tracking; integrate ITC into project financial model |
| Technology / innovation company | SR&ED (ongoing — confirm no planned rate changes); Clean Technology Manufacturing ITC; DST indirect effects; gig economy platform reporting for contractors | SR&ED claim documentation; assess Clean Tech Manufacturing ITC eligibility; correctly classify contractor income vs. employment |
| Gig economy worker / platform seller | Platform reporting requirements; CRA data matching (Airbnb, Etsy, Uber, etc.); crypto tax reporting | Ensure all platform income is reported; maintain expense documentation for deductible business costs; crypto transaction log; consider incorporation if income is substantial |
| High-income professional (doctor, lawyer, dentist) | Capital gains rate (professional corporation IP and share sales); individual AMT (large income years); TOSI rules (income splitting) | Professional corporation restructuring review; LCGE eligibility for professional corporation shares (province-specific); AMT modeling for high-income years |
| Manufacturing & industrial company | Clean Technology Manufacturing ITC; SR&ED for process improvements; minimum wage compliance increases | Assess Clean Tech Manufacturing ITC for any qualifying equipment investment; SR&ED documentation for R&D activities; update payroll for provincial minimum wage changes |
