Accounting Intelligence for Canadian Businesses — Patent Pending

Led by Bader A. Chowdry, CPA, CA, LPA — an AI Inventor and AI Specialist — our firm serves CCPCs, holding companies, and Canadian businesses across Mississauga, the GTA, Toronto, and throughout Ontario, helping them legally minimize tax liabilities while ensuring full compliance with Canada Revenue Agency (CRA) regulations.

Effective corporate tax planning isn’t just about filing returns—it’s about structuring your business for optimal tax efficiency year-round. Whether you’re operating a growing SME in Mississauga, managing a multi-entity corporate structure across Ontario, or expanding internationally from your Toronto headquarters, our strategic tax advisory services deliver measurable results.

Why Corporate Tax Planning Matters for Canadian Businesses

Canadian corporate tax law is complex and constantly evolving. The 2024 federal budget introduced significant changes, including the new capital gains inclusion rate of 2/3 effective June 25, 2026, modifications to the alternative minimum tax (AMT), and ongoing adjustments to the small business deduction thresholds. Without proactive planning, businesses across Canada risk overpaying taxes by tens or even hundreds of thousands of dollars annually.

Our Accounting Intelligence approach leverages advanced analytics to identify tax optimization opportunities that traditional accounting methods often miss. We serve businesses throughout the GTA and across Canada, providing the sophisticated tax strategies previously available only to large corporations with dedicated in-house tax departments.

Comprehensive Corporate Tax Services

CCPC Small Business Deduction ($500K Threshold)

The Canadian-Controlled Private Corporation (CCPC) small business deduction represents one of the most powerful tax advantages available to Canadian entrepreneurs. Qualifying CCPCs benefit from the small business deduction (SBD), which provides a reduced federal tax rate of approximately 9% on the first $500,000 of active business income.

However, accessing and optimizing this benefit requires careful planning:

Associated Corporations Rules: If you or related persons control multiple corporations, the $500,000 business limit must be shared among associated companies. Strategic restructuring can help maximize this limit across your corporate group.

Passive Investment Income Impact: Starting in 2019, the small business deduction is gradually reduced when a CCPC and its associated corporations earn more than $50,000 of aggregate investment income. For every dollar of investment income above this threshold, the business limit is reduced by $5. Our planning ensures your corporate structure balances operational income with investment activities to preserve SBD eligibility.

Specified Corporate Income Restrictions: Income from personal services businesses or certain intercorporate arrangements may not qualify for the SBD. We review your revenue sources and client relationships to ensure your active business income maintains its preferred tax status.

Provincial Variations: Ontario’s small business deduction parallels the federal system but has its own nuances. The Ontario small business limit is also $500,000, with a provincial rate of 3.2%, making the combined federal-provincial rate approximately 12.2% for qualifying income. Businesses operating across multiple provinces face additional complexity that our tax planning addresses.

Salary vs. Dividend Optimization

One of the most impactful decisions owner-managers face is how to extract income from their corporation. The choice between salary and dividends has significant tax implications affecting both the corporation and the shareholder personally.

Salary Advantages:

Creates RRSP contribution room (18% of earned income)
Qualifies for Canada Pension Plan (CPP) contributions
May be more tax-efficient at certain income levels
Deductible to the corporation, reducing corporate taxable income
Can help optimize the small business deduction by reducing corporate income

Dividend Advantages:

Lower personal tax rates due to dividend tax credits
No CPP premiums required (saving both employer and employee portions)
No payroll tax remittances or T4 filing requirements
Potential for income splitting with family members (subject to TOSI rules)
More flexible timing of personal income recognition

The Integration Principle: Canada’s tax system is designed with integration in mind—meaning the total tax paid on business income should be roughly equivalent whether taken as salary or dividends. However, optimal extraction strategies vary based on:

Your personal marginal tax bracket
The corporation’s tax rate and available tax credits
RRSP contribution priorities
CPP benefit considerations
Access to lifetime capital gains exemption
Income splitting opportunities
Alternative Minimum Tax (AMT) implications

Our sophisticated modeling analyzes your specific situation to determine the optimal compensation mix. For many clients in Mississauga and the Toronto area, a hybrid approach—combining salary to maximize RRSP room and CPP benefits with dividend distributions—provides the best overall tax outcome.

Holding Company Structures

Holding companies serve as powerful tools for tax deferral, asset protection, and estate planning. By interposing a holding company between operating companies and shareholders, businesses across Ontario and Canada can achieve significant tax and operational benefits.

Tax Deferral Benefits: When operating companies pay tax-paid dividends to a holding company, these dividends are generally received tax-free under Section 112 of the Income Tax Act. This allows surplus cash to accumulate in the holding company without triggering immediate personal tax, effectively deferring taxation until funds are needed personally.

Asset Protection: Separating operating assets from investment assets limits liability exposure. If an operating company faces legal claims, assets held in a separate holding company may be protected from creditors.

Estate Freezing: Holding companies facilitate estate freezing techniques, allowing business owners to lock in the current value of their business for tax purposes while transferring future growth to the next generation. This can significantly reduce the tax burden on estate transfers.

Investment Income Segregation: By routing dividends through a holding company, investment activities can be separated from operating activities. This preserves the small business deduction for operating companies while allowing investment income to accumulate in a separate entity.

Succession Planning: Holding company structures provide flexibility for bringing in new shareholders, implementing buy-sell agreements, and facilitating gradual ownership transitions—critical for family businesses in the GTA planning multi-generational transfers.

Section 55 Considerations: Recent changes to Section 55 of the Income Tax Act have limited the tax-free intercorporate dividends in certain circumstances, particularly where dividends are part of a series of transactions to dispose of shares or property. Our tax planning ensures holding company structures remain compliant while achieving your objectives.

Income Splitting Strategies (Post-TOSI Rules)

The Tax on Split Income (TOSI) rules, significantly expanded in 2018, have fundamentally changed income splitting opportunities for private corporations. While many traditional strategies are now restricted, legitimate income splitting remains possible with proper structuring.

Understanding TOSI: TOSI applies to “split income” received by certain related individuals, taxing it at the highest marginal rate rather than at their personal rate. The rules are complex, with numerous exceptions based on the recipient’s involvement in the business.

Excluded Shares Exception: Adult children (18+) who own at least 10% of the corporation’s shares (by votes and value) may receive dividends at their personal tax rates if the corporation is not a professional corporation and less than 90% of its income is from services. This exception requires careful share structuring and business model considerations.

Reasonable Return Exception: Family members who contribute to the business—through work, capital, or assumed risk—may receive income based on a “reasonable return” for their contributions. Documenting these contributions and establishing reasonable compensation levels is essential.

Excluded Business Exception: Adults aged 18-24 who work in the business at least an average of 20 hours per week during the portion of the year the business operates may receive income at their personal tax rates. Hours tracking and documentation are critical.

Retained Earnings Strategies: While direct income splitting faces restrictions, distributing corporate earnings to a family trust and then investing those funds can provide indirect benefits. The investment income earned by family members from these distributions is not subject to TOSI.

Prescribed Rate Loans: Lending funds to a spouse or family member at the CRA prescribed rate (currently 5%, locked in at the time of the loan) allows investment income to be taxed in their hands. This strategy remains viable and can produce significant long-term tax savings when properly implemented.

Our tax planning for clients in Toronto, Mississauga, and across Ontario focuses on compliant structures that maximize family wealth while navigating the complex TOSI landscape.

Capital Gains Planning (New 2/3 Inclusion Rate 2026)

The 2024 federal budget announced significant changes to capital gains taxation, with the inclusion rate increasing from 1/2 to 2/3 for capital gains realized on or after June 25, 2026. This change substantially increases the tax cost of selling appreciated assets and makes proactive capital gains planning more critical than ever.

Understanding the Change: Currently, 50% of capital gains are included in income. After June 25, 2026, individuals will pay tax on 2/3 of capital gains above $250,000 annually. Corporations and trusts will face the 2/3 inclusion rate on all capital gains with no threshold.

Impact on Business Sales: For entrepreneurs planning to sell their businesses, the tax increase is substantial. A $2 million capital gain that previously generated $500,000 in taxable income will now generate approximately $1.28 million in taxable income (depending on the allocation between individuals and corporations).

Lifetime Capital Gains Exemption (LCGE): The LCGE allows qualifying individuals to shelter up to $1,250,000 (indexed) of capital gains on shares of a qualified small business corporation (QSBC). Proper structuring is essential to ensure shares qualify:

Asset Test: At least 90% of the corporation’s assets must be used in an active business carried on primarily in Canada
Holding Period: Shares must be held for at least 24 months prior to sale
Basic Asset Test: Throughout the 24-month period, more than 50% of the corporation’s assets must be used in an active Canadian business

Crystallization Strategies: Before the new inclusion rate takes effect, business owners may consider crystallizing gains to utilize their LCGE or rebasis shares at current values. This requires careful analysis of the tax costs versus benefits.

Charitable Giving: Donating appreciated securities to registered charities eliminates capital gains tax entirely while providing a donation tax credit. This strategy becomes even more attractive with the higher inclusion rate.

Capital Dividend Account (CDA): Corporate capital gains generate CDA credits, allowing tax-free distributions to shareholders. Strategic management of the CDA, including crystallizing unrealized gains at the current 50% inclusion rate before June 2026, can maximize tax-free extraction opportunities.

Estate Planning Implications: The higher inclusion rate makes it more important than ever to plan for the deemed disposition on death. Estate freezes, life insurance funding, and charitable bequests should be reviewed in light of the new rules.

Our tax advisors work with clients throughout Ontario to develop capital gains strategies that address the new 2/3 inclusion rate while preserving long-term wealth transfer objectives.

Estate and Succession Planning

Transferring your business to the next generation or preparing for an eventual sale requires sophisticated tax planning. Without proper structuring, estate taxes can consume up to 50% or more of your business value, leaving your heirs with a fraction of what you built.

The Deemed Disposition Problem: Under Canadian tax law, you’re deemed to have sold all your assets at fair market value immediately before death. For highly appreciated private company shares, this can trigger substantial capital gains tax even if no actual sale occurs.

Estate Freezing Techniques:

1. Section 86 Reorganization: Converts common shares into preferred shares with fixed values, while new common shares representing future growth are issued to the next generation or a family trust.

2. Section 85 Rollover: Allows assets to be transferred to a corporation at an elected amount (often the tax cost) rather than fair market value, deferring tax on the built-in gain.

3. Trust Structures: Family trusts can hold shares for the benefit of multiple family members, providing flexibility in income distribution and estate planning while potentially multiplying the LCGE among beneficiaries.

Life Insurance as Tax Shelter: Corporate-owned life insurance can fund tax liabilities on death through the capital dividend account mechanism. Upon death, the insurance proceeds (net of adjusted cost basis) flow into the corporation’s CDA, enabling tax-free distributions to shareholders or estate beneficiaries.

Succession Planning for Family Businesses: Transitioning management and ownership to the next generation involves more than tax planning—it requires developing capable successors, establishing governance structures, and managing family dynamics. Our holistic approach addresses both the technical tax aspects and the practical challenges of family business succession.

Third-Party Sales: For business owners planning to sell to outside buyers, pre-sale planning can significantly enhance after-tax proceeds. This includes:

Purifying the corporation to meet QSBC status
Accelerating discretionary expenses before sale
Timing the sale to optimize personal and corporate tax years
Structuring the transaction (share sale vs. asset sale)
Negotiating earn-outs and vendor take-backs

International Tax Considerations

Canadian businesses expanding internationally or foreign companies entering the Canadian market face complex tax challenges. Our international tax planning services help businesses navigate cross-border transactions, permanent establishment issues, and foreign tax credit planning.

Permanent Establishment (PE) Risk: Operating in foreign jurisdictions can create PE status, triggering local corporate tax obligations and compliance requirements. Proper structuring—using subsidiaries, branches, or limited-risk distributors—can optimize global tax efficiency.

Foreign Accrual Property Income (FAPI): Canadian corporations with controlled foreign affiliates earning passive income face immediate Canadian tax on that income through the FAPI rules. Understanding and planning around these rules is essential for international investment structures.

Withholding Tax Planning: Cross-border payments of dividends, interest, and royalties are subject to withholding taxes. Canada’s tax treaties reduce these rates, but proper structuring can further optimize withholding tax outcomes.

Cross-Border Employee Arrangements: Sending employees to work in foreign jurisdictions or bringing foreign workers to Canada creates payroll tax, social security, and permanent establishment risks. We help structure arrangements to minimize these exposures.

GST/HST on International Transactions: The GST/HST implications of importing goods, exporting services, and international drop-shipping arrangements are complex. Proper classification and documentation ensure compliance while optimizing cash flow.

Foreign Tax Credits: Canadian corporations claiming foreign tax credits must navigate complex computational rules and limitations. Proper planning ensures maximum utilization of credits while avoiding double taxation.

Transfer Pricing Basics

For businesses engaged in cross-border transactions with related parties, transfer pricing rules require that prices charged between entities be consistent with arm’s length principles. Non-compliance can result in significant adjustments, penalties of up to 10% of the adjusted amount, and double taxation.

Documentation Requirements: The CRA requires contemporaneous transfer pricing documentation for certain taxpayers. This includes a master file (global business overview), local file (Canadian-specific information), and country-by-country reporting for large multinational groups.

Arm’s Length Principle: Transactions between related parties must be priced as if they were conducted between unrelated parties. This applies to:

Sale of tangible goods
Provision of services
Use of intangible property
Financing arrangements
Cost sharing agreements

Common Adjustments: The CRA frequently challenges:

Management fees charged to Canadian subsidiaries
Royalty payments for intellectual property
Interest rates on intercompany loans
Pricing of goods in distribution arrangements
Cost allocations in shared service centers

Advance Pricing Arrangements (APAs): For complex arrangements or significant exposure, obtaining an APA from the CRA provides certainty and reduces audit risk. Both unilateral (CRA-only) and bilateral (treaty partner involvement) APAs are available.

Penalty Protection: Maintaining contemporaneous documentation meeting CRA standards provides penalty protection even if adjustments are ultimately made. Documentation should be prepared annually and updated for significant changes.

Scientific Research Credits (SR&ED)

Canada’s Scientific Research and Experimental Development (SR&ED) program provides substantial tax incentives for businesses conducting R&D. Understanding how SR&ED credits interact with your overall tax position is essential for maximizing benefits.

Federal Credits: CCPCs can earn refundable investment tax credits (ITCs) of 35% on qualified SR&ED expenditures up to a threshold amount, and 15% on expenditures above the threshold. Non-CCPCs and large CCPCs receive 15% non-refundable ITCs.

Provincial Credits: Ontario provides additional credits, including:

Ontario Innovation Tax Credit (OITC): 8% refundable credit for qualifying corporations
Ontario Research and Development Tax Credit (ORDTC): 3.5% non-refundable credit

Proxy Method vs. Traditional Method: SR&ED claimants can calculate overhead and administrative support costs using either the traditional method (actual cost tracking) or the proxy method (calculated as 55% of salaries). The optimal method varies by company and should be evaluated annually.

Contracted SR&ED: Payments to third parties for SR&ED work may qualify for credits, but limitations apply (generally 80% of the payment amount for Canadian contractors, different rules for foreign contractors).

Interaction with Other Incentives: SR&ED expenditures affect other tax calculations, including the small business deduction limit and investment tax credit clawbacks. Comprehensive planning ensures SR&ED claims don’t inadvertently increase tax in other areas.

CRA Scrutiny: SR&ED claims face high audit rates, and the CRA has taken increasingly aggressive positions on what constitutes eligible work. Proper documentation, contemporaneous time tracking, and technical descriptions are essential for successful claims.

Frequently Asked Questions

What is corporate tax planning, and why does my business need it?

Corporate tax planning is the strategic analysis and structuring of your business affairs to legally minimize tax liability while ensuring compliance with CRA regulations. Every business earning taxable income needs tax planning—without it, you’re likely overpaying taxes and missing opportunities for wealth preservation and growth. Proactive planning can reduce your effective tax rate, optimize cash flow, and position your business for long-term success.

How does the new capital gains inclusion rate affect my business?

Effective June 25, 2026, the capital gains inclusion rate increases from 1/2 to 2/3 for corporations and for individual gains exceeding $250,000 annually. This significantly increases the tax cost of selling appreciated assets, including your business. If you’re considering a sale, estate freeze, or major asset disposition, planning before this deadline could save substantial tax. Contact us to discuss crystallization strategies and LCGE utilization.

Can I still income split with my family members after the TOSI rules?

Yes, but the rules are more restrictive. Adult children who own at least 10% of the corporation may receive dividends at their personal tax rates if the corporation meets certain criteria. Family members who work in the business or contribute capital may qualify for “reasonable return” exceptions. We can evaluate your structure and identify compliant income splitting opportunities specific to your situation.

What’s the difference between a share sale and an asset sale?

In a share sale, you sell your corporate shares, and the buyer acquires the entire corporation including all assets, liabilities, and tax history. This typically qualifies for the Lifetime Capital Gains Exemption if conditions are met. In an asset sale, the corporation sells specific assets to the buyer, often resulting in double taxation (corporate tax on the gain, plus personal tax when proceeds are distributed). The optimal structure depends on your specific situation and negotiation dynamics.

How can a holding company benefit my corporate structure?

A holding company provides several benefits: tax deferral by receiving tax-paid dividends from operating companies without triggering personal tax; asset protection by separating operating risks from investment assets; estate planning flexibility through freeze structures and multi-generational wealth transfer; and investment income segregation to preserve the small business deduction for operating companies. The benefits must be weighed against compliance costs and complexity.

What should I do to prepare for a CRA tax audit?

Maintain organized, contemporaneous records including source documents, accounting records, and supporting calculations for all tax positions taken. Ensure related party transactions are properly documented with written agreements and transfer pricing analysis. Keep SR&ED documentation current and comprehensive. Consider audit insurance to cover professional fees. Most importantly, work with a tax advisor who can represent you effectively—having experienced representation significantly improves audit outcomes.

How do I know if my corporation qualifies for the small business deduction?

To qualify, your corporation must be a Canadian-Controlled Private Corporation (CCPC) with active business income earned in Canada. The $500,000 limit must be shared with associated corporations. Your corporation’s investment income, specified corporate income, and taxable capital can all impact eligibility. We can review your structure and identify strategies to maximize your small business deduction entitlement.
