Professional Corporation vs. Regular Corporation in Alberta: Key Tax and Liability Differences

Choosing the right business structure is one of the most important decisions any professional or business owner will make. For doctors, dentists, lawyers, accountants, engineers, and other licensed practitioners, understanding the difference between a Professional Corporation in Alberta and a regular corporation is essential – especially when it comes to tax planning, liability protection, ownership rules, and regulatory compliance.

Although both structures are incorporated under the Alberta Business Corporations Act, they operate very differently. Professional corporations are governed not only by provincial corporate law but also by professional regulatory colleges, making them more restrictive but also uniquely beneficial for certain individuals. Regular corporations offer greater flexibility, but they lack the specialized features that regulated professionals may require.In this comprehensive guide, we break down the major differences between these corporate structures, compare tax and liability rules, and highlight when each option is appropriate. We also explain how we,  at Business Alberta Online, help professionals set up their corporation correctly, efficiently, and in full compliance with Alberta requirements.

What Is a Professional Corporation in Alberta?

A Professional Corporation in Alberta is a specialized type of corporation reserved exclusively for members of regulated professions. While it is formed under the Alberta Business Corporations Act, it is also governed by rules and policies from the applicable professional college or association.

Key characteristics include:

  • Only licensed members of the same regulated profession may be shareholders and directors.
  • The corporation can ONLY provide services related to that profession.
  • The Articles of Incorporation must include restricted professional purpose clauses.
  • A professional college must approve the corporation’s name and structure before or after incorporation (varies by profession).
  • A professional corporation permit must be obtained annually from the regulatory body.

Examples of professions that qualify:

  • Physicians & Surgeons (CPSA)
  • Dentists (ADA&C)
  • Lawyers (Law Society of Alberta)
  • Chartered Professional Accountants (CPA Alberta)
  • Optometrists
  • Psychologists
  • Chiropractors
  • Pharmacists
  • Veterinarians
  • Professional Engineers & Geoscientists (APEGA — Permit to Practice)

Because these corporations are highly regulated, they must follow strict requirements regarding naming, ownership, voting rights, and business activities.

What Is a Regular (Standard) Corporation in Alberta?

A regular Alberta corporation, sometimes referred to as a general or standard corporation, is much more flexible and accessible. It is governed solely by the Alberta Business Corporations Act, without oversight from professional regulatory organizations.

Key characteristics:

  • Anyone can own shares, including individuals, holding companies, or investors.
  • No restricted purpose clause is required.
  • No professional permits are necessary.
  • Broad business activities are allowed, including trade, retail, services, and investments.
  • No restrictions on directors’ qualifications.

Regular corporations are ideal for most businesses not governed by a professional regulatory college.

Key Differences: Professional Corporation vs Regular Corporation

Below is a detailed comparison of the most important distinctions.

Liability Protection

Professional Corporation Liability (Regulated Professionals)

A professional corporation provides:

  • Limited liability for business or operational debts
  • No liability protection for professional negligence or malpractice

Regulated professionals remain personally responsible for:

  • Malpractice
  • Professional misconduct
  • Violations of college standards

Regular Corporation Liability

A regular Alberta corporation provides:

  • Limited liability for all business-related matters
  • No professional negligence liability issues, because regular corporations do not provide regulated professional services

Both types offer business liability protection, but professional negligence is NOT shielded by a professional corporation.

Tax Treatment

Understanding tax differences is crucial – especially for high-earning professionals.

Corporate Tax Rates

Both professional and regular corporations benefit from Alberta’s competitive small business tax rate if they qualify.

Small Business Deduction (SBD)

Professional corporations may qualify for the Small Business Deduction, allowing income to be taxed at a lower rate, significantly reducing the tax burden.

Tax Deferral

Professionals earning high income benefit from:

  • Leaving profits inside the corporation at lower tax rates
  • Deferring personal tax until funds are withdrawn

Income Splitting Rules

Professional corporations face stricter rules:

  • Only individuals actively involved in the business may receive dividends (varies by federal rules)
  • Family income splitting is limited

Dividend vs Salary Flexibility

Like regular corporations, professional corporations can:

  • Pay dividends
  • Pay salaries
  • Use a combination for tax planning

While both structures offer tax planning benefits, professional corporations are specifically optimized for long-term income deferral and retirement planning.

Ownership & Share Structure

Professional Corporations

  • Only licensed members of the same profession may hold voting shares
  • Some colleges restrict any outside ownership
  • Shareholders must be approved or recognized by the regulatory college
  • Family members may own non-voting shares in some professions, but rules vary

Regular Corporations

  • Shares can be owned by anyone
  • No restrictions on voting or non-voting shares
  • Investors, partners, or holding companies can participate freely

Professional corporations have significantly tighter ownership rules.

Regulatory Oversight

Professional Corporations

Subject to both:

  • Alberta Corporate Registry
  • Professional regulatory college

Annual Requirements:

  • Corporate Annual Return
  • Professional Corporation Permit Renewal
  • Compliance with college rules
  • Use of restricted professional purpose

Regular Corporations

Subject only to:

  • Alberta Corporate Registry requirements

No additional permits, approvals, or regulatory supervision.

Naming Rules

Professional Corporation Naming Rules

Must include:

  • The profession (e.g., “Medicine,” “Law,” “Dentistry”)
  • Surname of the professional (varies by college)
  • “Professional Corporation”

Examples:

  • John Doe Medical Professional Corporation
  • Smith Dental Professional Corporation

Naming must be approved by the regulatory college.

Regular Corporation Naming Rules

Must include:

  • A distinctive element
  • A descriptive element
  • A legal ending (Ltd., Inc., Corp.)

No profession-specific requirements.

Permitted Activities

Professional Corporations

  • May only provide services within the regulated profession
  • Some passive investment activities are allowed
  • No unrelated business activities permitted

Regular Corporations

  • Can engage in any lawful business
  • No restrictions on additional business interests

Tax Advantages of a Professional Corporation in Alberta

A Professional Corporation in Alberta offers several important tax advantages, including:

  • Tax deferral through retained earnings
  • Eligibility for the small business tax rate (subject to federal restrictions)
  • Corporate savings access for retirement planning
  • Potential investment income in the corporation
  • Flexible compensation planning (salary vs dividends)

However, income splitting is more limited due to federal tax reforms.

Liability Differences in Detail

Professional corporations DO NOT protect regulated professionals from:

  • Professional negligence
  • Errors or omissions
  • Breaches of ethical standards

Only business liabilities (leases, loans, contracts) receive limited liability protection.

Regular corporations do not have these restrictions because they do not involve professional conduct oversight.

Professional colleges can still:

  • Investigate
  • Discipline
  • Suspend or revoke licenses
  • Enforce ethical standards

This remains entirely separate from corporate liability protection.

When a Professional Corporation Is the Better Choice

A professional corporation is ideal when:

  • You are a doctor, dentist, lawyer, accountant, optometrist, psychologist, pharmacist, chiropractor, or veterinarian
  • You expect high personal income
  • You want long-term tax deferral
  • You plan to grow your professional practice
  • Your regulatory college encourages or requires incorporation

You want formal business structure and succession planning

When a Regular Alberta Corporation Makes More Sense

A regular corporation is better suited for:

  • Entrepreneurs
  • Retail businesses
  • Construction companies and trades
  • Consultants who are not part of a regulated profession
  • Startups and tech companies
  • Businesses that plan to seek investors

Regular corporations offer maximum flexibility in ownership and business activities.
