Corporate Tax Rates Canada 2025: What Business Owners Need to Know

Corporate income tax rate Canada varies significantly depending on your business structure and location. In 2025, the standard corporate tax rate stands at 26.50 percent, a substantial decrease from the all-time high of 50.90 percent recorded in 1981. However, small businesses operating as Canadian-controlled private corporations (CCPCs) benefit from a much lower federal tax rate of just 9%.

Understanding these tax differences is crucial for effective business planning. The federal corporate income tax basic rate starts at 38%, but after applying a 10% federal tax abatement and a 13% general tax reduction, the effective rate for general corporations drops to 15%. Additionally, businesses involved in zero-emission technology manufacturing can enjoy temporary rate reductions of up to 50%, lowering the general rate to 7.5% and the CCPC rate to 4.5% through 2031. Whether you’re managing a small business or a larger corporation, we’ll help you navigate the complex landscape of corporate taxation in Canada throughout this guide.

Federal Corporate Income Tax Rates (2025)

In 2025, Canadian businesses face a tiered federal corporate tax structure that varies based on company size, activities, and ownership. Understanding these rates forms the foundation of effective tax planning for any corporation operating in Canada.

Basic federal rate and general reduction

The federal corporate tax system starts with a basic rate of 38% on taxable income. This rate undergoes two major adjustments for most corporations. First, a federal tax abatement of 10% reduces the rate to 28% for income earned in Canadian provinces and territories. Subsequently, a general tax reduction of 13% further lowers the rate to a net federal tax of 15% for most corporations.

This 15% rate applies to general corporations including public companies, their Canadian subsidiaries, and Canadian-resident private companies controlled by non-residents. Nevertheless, certain types of income don’t qualify for the general rate reduction, such as personal services business income, which faces a substantially higher federal tax rate of 33%.

Small business deduction (SBD) explained

For Canadian-controlled private corporations (CCPCs), the small business deduction offers substantial tax savings, reducing the federal tax rate to just 9% on qualifying active business income. This preferential rate applies to the first CAD 696,680.10 of active business income in 2025.

The SBD is subject to important limitations:

1. The business limit must be shared among associated CCPCs
2. The limit begins to reduce when a CCPC’s taxable capital exceeds CAD 13.93 million in the previous tax year
3. The deduction is completely eliminated when taxable capital reaches CAD 69.67 million
4. For taxation years after 2018, the SBD is also reduced if a CCPC earns passive investment income exceeding CAD 69,668.01 in the preceding tax year and eliminated when this income exceeds CAD 209,004.03

Notably, Ontario and New Brunswick have enacted legislation that does not parallel the federal SBD reduction with respect to passive investment income. This means eligible small businesses in these provinces can receive their provincial small business deduction regardless of passive income levels.

Zero-emission technology tax incentives

As part of Canada’s green initiatives, federal tax rates are temporarily reduced by 50% for qualifying zero-emission technology manufacturing and processing activities. For general corporations, the rate drops from 15% to 7.5%, while eligible CCPCs benefit from a reduced rate of 4.5% instead of the standard 9% small business rate.

To qualify for these incentives:

• At least 10% of the company’s gross revenues from all active businesses in Canada must come from eligible zero-emission technology manufacturing and processing activities
• The reduced rates apply to taxation years beginning after 2021
• The incentives will be gradually phased out starting in taxation years beginning in 2032
• The rates will return to standard levels for taxation years beginning after 2034

This temporary measure aims to boost Canada’s clean technology sector while supporting the country’s environmental objectives.

Special rules for banks and insurers

Financial institutions face additional tax burdens beyond the standard corporate rates. Banks and life insurers are subject to an additional tax of 1.5% on taxable income, effectively increasing their federal tax rate from 15% to 16.5%.

This supplementary tax includes an exemption threshold of CAD 139.34 million in taxable income, which must be shared among members of a financial group. The exemption helps shield smaller financial institutions while ensuring larger banks and insurers contribute additional tax revenue.

Furthermore, Canada introduced a one-time 15% Canada Recovery Dividend for the 2022 taxation year, applicable to a financial institution group’s average 2020-2021 taxable income (subject to a CAD 1.39 billion exemption shared by group members). This special dividend is payable over a five-year period ending in 2026.

The federal corporate tax landscape consequently reflects Canada’s policy priorities: supporting small businesses, encouraging green technology adoption, and requiring larger financial institutions to contribute proportionally more to government revenues.

Provincial and Territorial Corporate Tax Rates (2025)

Beyond the federal tax framework, Canadian businesses must navigate a complex provincial and territorial tax landscape in 2025. Each jurisdiction imposes its own corporate tax rates, creating significant regional variations that smart business owners must factor into their financial planning.

Overview of provincial tax structures

Throughout Canada, provinces and territories generally maintain two distinct corporate tax rates – a lower rate for small businesses eligible for the small business deduction (SBD) and a higher rate for all other income. These rates vary considerably across the country, creating important financial implications for business location decisions.

In 2025, the lower SBD rates range from as little as 0% in Manitoba and Yukon to 3.2% in Ontario and Quebec. For general corporate income not eligible for the SBD, the higher rates span from 8% in Alberta to 15% in Newfoundland and Labrador and Prince Edward Island (after July 1, 2025).

Recent provincial tax changes include:

• Nova Scotia reduced its small business rate from 2.5% to 1.5% effective April 1, 2025
• Prince Edward Island announced a reduction in its general corporate tax rate from 16% to 15% effective July 1, 2025
• Newfoundland and Labrador reduced its small business rate from 3% to 2.5% effective January 1, 2024

Coupled with federal rates, these provincial taxes create combined corporate tax rates for general corporations typically ranging between 23% and 30%, depending on location.

Small business limits by province

In essence, the small business limit determines how much active business income qualifies for the preferential SBD rate. Unlike the federal limit of $696,680.10 in 2025, provinces can set their own thresholds.

Most provinces align with the federal limit, yet several exceptions exist:

• Saskatchewan maintains a higher limit of $836,016.12
• Nova Scotia increased its limit from $696,680.10 to $975,352.14 effective April 1, 2025
• Prince Edward Island will increase its limit to $836,016.12 effective July 1, 2025

Interestingly, Quebec imposes unique eligibility requirements for its SBD. Quebec-based corporations must meet a minimum threshold of 5,500 paid hours annually to access the full SBD. The deduction reduces linearly when hours fall between 5,500 and 5,000, disappearing entirely below 5,000 hours.

The provincial small business deduction is typically subject to the same restrictions as the federal SBD regarding taxable capital. In particular, the limit begins phasing out when taxable capital exceeds $13.93 million and disappears entirely at $69.67 million. Nevertheless, Ontario and New Brunswick diverge from federal practice by not implementing the passive investment income restriction to their provincial business limits.

Manufacturing and processing rate reductions

Several provinces offer preferential tax treatment for manufacturing and processing (M&P) activities, recognizing their economic importance. In contrast to the general rates, these specialized rates encourage industrial development and innovation.

Ontario provides the most substantial M&P benefit, with a reduced rate of 10% compared to its general 11.5% rate. Similarly, Saskatchewan offers M&P businesses a preferential rate of 10% versus its 12% general rate.

Yukon offers the most dramatic reduction for M&P income with a rate of just 2.5% compared to its general 12% rate, representing a 9.5 percentage point difference.

The eligibility for manufacturing and processing benefits remains relevant even though the federal M&P deduction now matches the general rate reduction. As a matter of fact, determining what qualifies as M&P activity follows specific guidelines that consider factors such as:

• The nature of processing activities
• Capital equipment investment
• Manufacturing facility operations

Prior to making investment decisions based on these rates, businesses should consult tax professionals to ensure they meet all eligibility requirements for these specialized provincial tax treatments.

Combined Corporate Tax Rates by Region

Understanding the actual tax burden for Canadian businesses requires looking at the combined effect of federal and provincial rates. For business owners making strategic decisions about where to operate, these combined rates often carry more weight than individual tax components.

How federal and provincial rates combine

The combined corporate tax rate in Canada is straightforward to calculate—simply add the applicable federal rate to the provincial or territorial rate. Yet this simplicity belies important regional differences that can significantly impact a company’s bottom line.

For general corporations, the combined rate equals the federal general rate of 15% plus the applicable provincial higher rate. For Canadian-controlled private corporations (CCPCs) eligible for the small business deduction, the combined rate equals the federal small business rate of 9% plus the provincial lower rate.

Effectively, the calculation differs based on whether your business income qualifies for the small business deduction:

1. For general corporate income: Federal rate (15%) + Provincial/territorial higher rate
2. For active business income eligible for SBD: Federal rate (9%) + Provincial/territorial lower rate

Moreover, businesses involved in manufacturing and processing activities may enjoy additional provincial rate reductions in certain jurisdictions. Specifically, Ontario offers a reduced rate of 10% instead of 11.5%, while Saskatchewan provides a 10% rate rather than 12% for manufacturing operations.

Examples of total tax rates in key provinces

The provincial variations create a diverse tax landscape across Canada. Here’s how the 2025 combined corporate tax rates break down for major business jurisdictions:

Alberta: With the lowest general provincial rate in the country at 8%, Alberta businesses face a combined general rate of 23% (15% federal + 8% provincial). Small businesses eligible for the SBD enjoy a combined rate of 11% (9% federal + 2% provincial).

Ontario: Canada’s largest provincial economy imposes a combined general rate of 26.5% (15% federal + 11.5% provincial). For manufacturing and processing businesses, this decreases to 25% (15% federal + 10% provincial). Small businesses benefit from a combined rate of 12.2% (9% federal + 3.2% provincial).

British Columbia: Companies face a combined general rate of 27% (15% federal + 12% provincial). For small businesses, the combined rate sits at 11% (9% federal + 2% provincial).

Quebec: Corporate entities encounter a combined general rate of 26.5% (15% federal + 11.5% provincial). Small businesses meeting Quebec’s unique 5,500 paid hours eligibility requirement pay a combined rate of 12.2% (9% federal + 3.2% provincial).

Nova Scotia: Following recent changes effective April 1, 2025, Nova Scotia offers a combined small business rate of 10.5% (9% federal + 1.5% provincial) on eligible income up to $975,352.14. The general rate remains at 29% (15% federal + 14% provincial).

Prince Edward Island: Starting July 1, 2025, PEI will reduce its general rate to 15%, creating a combined rate of 30% (15% federal + 15% provincial). Additionally, PEI will increase its business limit to $836,016.12, allowing more income to qualify for its combined small business rate of 10% (9% federal + 1% provincial).

For investment income earned by corporations, the combined rates are substantially higher. The federal component alone is 38.67%, which when added to provincial rates results in combined rates ranging from 46.67% in Alberta (38.67% federal + 8% provincial) to 54.67% in Prince Edward Island (38.67% federal + 16% provincial).

Ultimately, these combined corporate tax rates play a crucial role in business location decisions, with rate differences of up to 7 percentage points between provinces offering potential tax savings for businesses with the flexibility to choose their operating jurisdiction.

Corporate Tax Rates for Small Businesses (CCPCs)

Small businesses structured as Canadian-controlled private corporations (CCPCs) enjoy significant tax advantages that can substantially boost profitability and growth potential. The preferential tax treatment for CCPCs represents one of Canada’s most important fiscal policies to support domestic entrepreneurship and economic development.

Eligibility for CCPC status

First and foremost, qualifying as a CCPC requires meeting several specific criteria. A corporation must be a private corporation that was resident in Canada and was either incorporated in Canada or resident in Canada from June 18, 1971, to the end of the tax year.

To maintain CCPC status, a company cannot be:

• Controlled directly or indirectly by one or more non-resident persons
• Controlled directly or indirectly by one or more public corporations (except prescribed venture capital corporations)
• Controlled by a Canadian resident corporation that lists its shares on a designated stock exchange outside of Canada
• Controlled by any combination of the above entities

In essence, a CCPC must be genuinely controlled by Canadian residents, with no class of its shares listed on any designated stock exchange. This status serves as a prerequisite for numerous tax incentives, including the valuable small business deduction.

Federal and provincial small business rates

In 2025, the federal small business tax rate for CCPCs stands at 9% on qualifying active business income up to the small business limit. This represents a substantial reduction from the general corporate tax rate of 15%, creating meaningful tax savings for smaller enterprises.

At the provincial level, small business rates vary considerably:

• 0% in Manitoba and Yukon
• 1% in Prince Edward Island and Saskatchewan
• 1.5% in Nova Scotia (reduced from 2.5% effective April 1, 2025)
• 2% in British Columbia, Alberta, and Northwest Territories
• 2.5% in New Brunswick and Newfoundland and Labrador
• 3% in Nunavut
• 3.2% in Ontario and Quebec

When combined with the federal rate, these create total small business tax rates ranging from 9% in Manitoba and Yukon to 12.2% in Ontario and Quebec. Certainly, this represents a significant advantage compared to the combined general corporate rates that typically range between 23% and 31%.

Additionally, several provinces have increased their small business limits beyond the federal threshold of $696,680.10:

• Saskatchewan: $836,016.12
• Nova Scotia: $975,352.14 (effective April 1, 2025)
• Prince Edward Island: $836,016.12 (effective July 1, 2025)

Impact of passive investment income

Despite these advantages, CCPCs face restrictions when they generate substantial passive investment income. Since 2019, passive income (like interest, rent, and royalties) exceeding $69,668.01 in the previous tax year reduces the small business deduction limit in the current year.

This reduction occurs at a rate of $6.97 for each $1.39 of passive income above the threshold. Once passive income reaches $209,004.03, the small business deduction is completely eliminated. Notably, Ontario and New Brunswick have opted not to implement this passive income restriction for their provincial small business limits.

Passive income earned within a CCPC is typically taxed at approximately 50% across Canada. This elevated rate comprises both refundable and non-refundable portions. The refundable portion returns to the corporation when dividends are distributed to shareholders.

Capital gains receive somewhat more favorable treatment, being taxed at about half the passive income rate since only 50% of capital gains are taxable. The non-taxable portion gets added to the Capital Dividend Account, which can later be distributed tax-free to shareholders.

Understanding these restrictions remains vital for tax planning. For business owners expecting to withdraw corporate earnings immediately as salary or dividends, the impact of losing the SBD may be minimal due to integration principles. Nevertheless, for those planning to retain earnings within the corporation, protecting access to the SBD through careful planning of passive investments becomes a critical consideration.

Corporate Tax on Investment Income and Capital Gains

Corporations that accumulate surplus cash often generate investment income beyond their core business activities. For tax purposes, this passive income faces distinct treatment from active business income, with higher rates and complex refundable mechanisms designed to prevent companies from using corporate structures as tax shelters.

What qualifies as investment income

Investment income for Canadian corporations encompasses several distinct categories that attract specific tax treatment. Initially, this includes interest income, rental income, royalty income, foreign dividend income, and taxable capital gains. Essentially, any income derived from property rather than active business operations qualifies as investment income.

To determine aggregate investment income, corporations must calculate their worldwide source income by adding eligible portions of taxable capital gains and income from property, then deducting exempt income, AgriInvest receipts, taxable dividends, and business income from certain trusts. Meanwhile, losses from property-related activities are subtracted from this calculation.

For Canadian-controlled private corporations (CCPCs), investment income (other than most dividends) faces a substantially higher federal tax rate of 38⅔%, which includes a base rate of 28% plus a refundable federal tax of 10⅔%. This elevated rate discourages businesses from using corporations primarily as investment vehicles.

Capital gains inclusion rate

The capital gains inclusion rate represents the portion of capital gains that is taxable. Throughout 2025, the inclusion rate for corporations remains at 50%, meaning only half of realized capital gains are subject to tax. The non-taxable half of capital gains is added to the capital dividend account (CDA), which can later be distributed tax-free to shareholders.

In early 2025, the federal government had announced plans to increase the inclusion rate from one-half to two-thirds on all capital gains realized by corporations, effective January 1, 2026. This change would have substantially increased the tax burden on corporate investment activities. The implementation date was originally set for June 25, 2024, but was subsequently deferred to January 1, 2026.

However, on March 21, 2025, Prime Minister Carney announced the cancelation of this proposed capital gains inclusion rate increase. According to the announcement, this decision was made to strengthen “Canada’s ability to catalyze the enormous private investment needed to create jobs and opportunities”. As a result, corporations will continue to pay tax on only 50% of capital gains for the foreseeable future.

Refundable tax on investment income

A distinctive feature of corporate investment taxation is the refundable dividend tax on hand (RDTOH) system. For CCPCs, 30.67% of investment income is added to their non-eligible RDTOH (NERDTOH) account. This system allows corporations to recover a portion of taxes paid when they distribute dividends to shareholders.

Since 2019, RDTOH has been divided into two accounts:

1. NERDTOH: Tracks refundable taxes paid on investment income (interest, foreign income, taxable capital gains)
2. ERDTOH: Tracks refundable taxes paid on eligible Canadian dividends

When a corporation pays taxable dividends to shareholders, it receives a dividend refund at a rate of CAD 1.39 for every CAD 3.64 of dividends paid, up to the balance in the respective RDTOH account. Non-eligible dividends generate refunds from NERDTOH first, before potentially drawing from ERDTOH.

The dividend refund mechanism achieves an important principle known as “integration” in the Canadian tax system. Perfect integration means an individual would be indifferent between earning investment income personally or through a corporation. In practice, the combined corporate and personal tax rates on investment income often exceed 50% in many provinces.

For corporations receiving dividends from other Canadian corporations, special rules apply. Dividends from “non-connected” Canadian corporations (portfolio dividends) are subject to a 38.33% refundable tax, which is added to the ERDTOH account. Meanwhile, dividends can flow tax-free between connected corporations where appropriate ownership thresholds are met.

Global Tax Framework and Canada’s Response

The international tax landscape is rapidly changing, with major reforms affecting how multinational enterprises (MNEs) operate across borders. Canada, as a G7 nation, actively participates in these global tax initiatives while developing its own responses to digital economy challenges.

Overview of Pillar One and Pillar Two

The OECD’s two-pillar approach represents a fundamental shift in international taxation principles. Pillar One reallocates taxing rights to market jurisdictions where customers reside, primarily targeting large digital businesses and consumer-facing MNEs with global revenue exceeding €20 billion. This approach moves beyond the traditional physical presence requirement for establishing tax nexus.

Pillar Two introduces a global minimum corporate tax rate of 15% for MNEs with annual revenue above €750 million. This framework includes:

• Income Inclusion Rule (IIR): Allowing parent jurisdictions to top-up tax on low-taxed income
• Undertaxed Payments Rule (UTPR): Denying deductions or requiring adjustments when income isn’t subject to minimum taxation
• Subject to Tax Rule (STTR): Permitting source jurisdictions to tax certain related-party payments not taxed at the minimum rate

Canada has officially endorsed both pillars as part of its commitment to international tax cooperation and preventing base erosion.

Canada’s digital services tax (DST)

Concurrently, Canada has developed its own Digital Services Tax as a stopgap measure until Pillar One becomes fully implemented. The Canadian DST applies a 3% tax on revenue derived from certain digital services reliant on Canadian users’ engagement and data.

The tax targets businesses with:

• Global revenue of €750 million or more
• In-scope Canadian revenue exceeding CAD $20 million

Covered activities include online marketplaces, social media platforms, online advertising, and user data sales. Uniquely, Canada’s DST is designed as a backstop, with retroactive application intended to prevent revenue loss during the Pillar One implementation process.

Implementation timeline and impact on MNEs

Canada originally planned to implement its DST effective January 1, 2022, but postponed application pending Pillar One developments. Presently, the DST legislation remains in place but with delayed enforcement until 2025 or until major trading partners implement similar measures.

For multinational enterprises, these changes create both challenges and opportunities:

1. Increased compliance complexity across multiple jurisdictions
2. Potential double taxation risks during transition periods
3. Need for revised transfer pricing and business structuring strategies

Throughout this evolution, Canadian businesses must balance domestic tax planning with international tax considerations. Notably, these global frameworks may eventually reduce the competitive advantage of Canada’s relatively moderate corporate tax rates compared to lower-tax jurisdictions.

As tax authorities worldwide cooperate more closely, proactive tax governance becomes increasingly vital for companies with cross-border operations.

Tax Rate Changes and Historical Trends

Looking back at Canada’s tax landscape reveals a pattern of gradual reductions coupled with strategic adjustments to support economic priorities. As 2025 unfolds, several noteworthy changes continue this evolutionary trend.

Recent changes in federal and provincial rates

Over the past year, multiple provinces implemented significant tax adjustments. Nova Scotia lowered its small business rate from 2.5% to 1.5% effective April 1, 2025. Meanwhile, Prince Edward Island announced a reduction in its general corporate tax rate from 16% to 15% starting July 1, 2025. Earlier, Newfoundland and Labrador decreased its small business rate from 3% to 2.5% effective January 1, 2024.

In Saskatchewan, the small business rate first decreased from 2% to 0% in October 2020, then rose to 1% in July 2023, with legislation now maintaining this rate indefinitely. Throughout these changes, the federal general corporate tax rate has remained stable at 15% since 2012.

Trends in small business limits

Perhaps more important than rate changes is the evolving threshold for small business deductions. Between 2001 and 2019, the federal small business limit more than doubled from CAD 278,672.04 to CAD 696,680.10. This expansion made preferential rates accessible to more businesses with higher taxable income.

Several provinces now exceed the federal threshold:

• Saskatchewan: CAD 836,016.12
• Nova Scotia: CAD 975,352.14 (effective April 1, 2025)
• Prince Edward Island: CAD 836,016.12 (effective July 1, 2025)

Furthermore, the upper limit of taxable capital at which the SBD is fully eliminated increased dramatically from CAD 20.90 million to CAD 69.67 million, benefiting medium-sized CCPCs.

Comparison with historical highs and lows

Today’s rates represent historic lows compared to past decades. The federal general corporate rate peaked at 47% in the 1950s before declining to 36% in 1980, 28% in 1990, and 21% by 2007. Currently, Canada’s combined federal-provincial corporate tax rates average around 26.5%, down substantially from 42.4% in earlier years.

For small businesses, the combined federal-provincial tax rate decreased from 20% in 2001 to approximately 14% by 2019. This downward trajectory reflects Canada’s deliberate strategy to improve business competitiveness while balancing revenue needs.

Canada vs USA: Corporate Tax Comparison

When examining corporate taxation across North America, the divergent approaches between Canada and the United States create meaningful implications for businesses operating on either side of the border.

Federal and state tax structures in the US

To begin with, the United States employs a flat federal corporate tax rate of 21%, distinctly higher than Canada’s general federal rate of 15%. In addition to this federal layer, American corporations face state-level taxes ranging from 0% to over 11%, depending on their location.

The US corporate tax structure includes:

• Federal corporate tax (21%)
• State corporate income taxes (0-11+%)
• Local government taxes that vary by jurisdiction

As opposed to Canada’s provincial system, American state corporate taxes can be deducted when calculating federal taxable income, effectively reducing the combined tax burden.

Effective tax rate comparison

After accounting for state tax deductibility, the average net effective rate for US corporations reaches approximately 28%. For comparison, Canadian businesses typically face combined federal-provincial rates between 23% and 31%.

This marks a significant shift from pre-2017, when Canada enjoyed a substantial competitive advantage with rates approximately 27% versus America’s former 39%. The 2017 US tax reforms dramatically altered this landscape, reducing the US marginal effective tax rate from around 35% to 19%.

First thing to remember for small businesses—both countries offer preferential treatment. Canada provides the small business deduction for CCPCs, while the US offers Section 199A deductions for certain pass-through entities. For Canadian-controlled private corporations, federal rates can be as low as 9% on eligible income, whereas US small businesses often utilize partnerships, S corporations, or sole proprietorships to achieve tax efficiency.

Cross-border tax planning considerations

Equally important for businesses operating across the border is understanding recent US tax enhancements, including the “Big Beautiful Bill” that makes 100% bonus depreciation permanent for qualified property placed into service after January 2025. This immediate expensing advantage may influence capital investment decisions between the two countries.

For instance, cross-border businesses should carefully time capital investments to maximize deductions while matching depreciation schedules between jurisdictions. Given that each country’s tax system treats foreign-source income differently, proper structuring becomes essential to avoid double taxation while maintaining compliance with “permanent establishment” rules.

Overall, the tax systems have converged in recent years, with the US gaining competitive ground through its 2017 reforms. Businesses must now evaluate location decisions based on total tax burden rather than just headline rates.

Conclusion

Navigating the complex world of Canadian corporate taxation requires meticulous planning and up-to-date knowledge. Throughout 2025, businesses face a tiered system with federal rates ranging from 9% for eligible CCPCs to 15% for general corporations, while provincial rates add another layer of complexity. Small business owners benefit significantly from the small business deduction, though passive income restrictions may limit these advantages. Additionally, the substantial differences between provincial tax structures create strategic opportunities for businesses with flexibility in their operations.

The historical downward trend in corporate tax rates has positioned Canada competitively on the global stage, despite recent US tax reforms narrowing this advantage. Meanwhile, international developments like the OECD’s two-pillar approach and Canada’s digital services tax will reshape how multinational enterprises manage their tax obligations. Capital gains taxation remains stable at a 50% inclusion rate after the government’s decision to cancel the proposed increase, thus preserving investment incentives.

Business structure, location, and activity type clearly impact your effective tax rate. CCPCs enjoy preferential treatment with combined rates as low as 9% in Manitoba and Yukon, while manufacturing businesses benefit from special provincial rate reductions in jurisdictions like Ontario and Saskatchewan. Therefore, selecting the optimal corporate structure and provincial home base could save your business thousands of dollars annually.
