What is the small business tax rate for incorporated wellness clinics in Ontario?

The combined federal-provincial small business rate in Ontario is about 11.2% since July 1, 2026 (9% federal + 2.2% provincial) on the first $500,000 of active business income — it was 12.2% before Ontario's rate cut, and fiscal years straddling that date pay a prorated blended rate. This compares to personal income tax rates that reach 53.53% at higher income levels.

Can all Ontario wellness practitioners incorporate?

Yes — chiropractors, physiotherapists, RMTs, acupuncturists, and naturopathic doctors can all incorporate in Ontario as professional corporations, subject to their respective regulatory college requirements.

What are the ongoing costs of running an incorporated clinic?

Expect accounting fees of $2,000–$5,000+ per year for corporate bookkeeping and T2 corporate tax returns (in addition to your personal T1), legal fees for maintaining the corporation, and a modest annual corporate filing fee. These are in addition to a personal T1 return.

Can I access the Lifetime Capital Gains Exemption if I incorporate?

Potentially yes. If your professional corporation qualifies as a Qualified Small Business Corporation (QSBC) at the time of sale, you may be able to shelter up to approximately $1,275,000 of capital gains (the limit was set at $1,250,000 for dispositions on or after June 25, 2024, with indexation resuming in 2026) on the sale of your corporation's shares from tax. It applies only where the corporation's shares meet the QSBC conditions at the time of sale.

Should I Incorporate My Wellness Clinic?

The Short Answer

Ontario’s small business corporate tax rate (about 11.2% since July 1, 2026) is lower than the top personal income tax rate (53.53%). Earnings retained in a corporation are taxed at the corporate rate, and personal tax applies only when the money is withdrawn — a timing difference known as deferral. Incorporation also carries added filing and accounting costs. Whether it is worthwhile depends on individual circumstances; the facts below explain how it works.

The Full Explanation

The Tax Rate Gap

The fundamental driver of incorporation savings is the difference between corporate and personal tax rates:

Structure	Tax Rate on Income
Sole proprietor (top bracket Ontario)	Up to 53.53%
Professional corporation (small business)	~11.2%

The difference between the corporate small business rate and a top personal rate can exceed 40 percentage points on income that is retained in the corporation rather than drawn personally.

Note: this is deferral, not permanent elimination. When the money is drawn out as salary or dividends, personal tax applies.

What You Can Do with a Corporation

Share ownership: For chiropractors, physiotherapists, RMTs, acupuncturists, and naturopathic doctors, all shares of the professional corporation must be owned by members of the profession. Ontario’s exception allowing family members to hold non-voting shares applies only to medicine and dentistry. Dividend income-splitting with family through share ownership is therefore generally not available to these professions.

Lifetime Capital Gains Exemption (LCGE): If you eventually sell your professional corporation’s shares and the corporation qualifies as a Qualified Small Business Corporation, the capital gain may be sheltered by the LCGE — set at $1,250,000 for dispositions on or after June 25, 2024 and indexed from 2026 (approximately $1,275,000). This is a major potential benefit for clinic owners planning an eventual sale.

Passive investment inside the corporation: Retained earnings in the corporation can be invested — in mutual funds, stocks, real estate, or other assets — within the corporate structure. Investment income earned inside a corporation has its own tax rules (the passive income rules), but the ability to invest pre-personal-tax dollars is a meaningful long-term wealth-building advantage.

Salary and dividends: A corporation owner can be paid by salary (T4), dividends, or a mix. Salary generates CPP contributions and RRSP contribution room; dividends do not, and are taxed at dividend rates (with the dividend tax credit). The appropriate mix depends on individual circumstances and is determined with a CPA.

The Costs of Incorporation

Incorporation is not free. Ongoing costs include:

Corporate tax return (T2): $1,500–$4,000+ per year, depending on complexity
Corporate bookkeeping: typically more complex than personal bookkeeping, with separate bank accounts, payroll, and shareholder loan tracking
Legal: annual maintenance filings, corporate resolutions, shareholder agreements
Professional college approval: some regulatory colleges require annual notification or approval of your corporation structure

Total additional annual cost: roughly $3,000–$7,000 for a simple professional corporation. These are in addition to a personal T1 return.

Regulatory College Requirements

All five wellness clinic practice types in Ontario can incorporate as professional corporations. Each has specific requirements set by their college:

Chiropractors (CCO): Must obtain CCO approval; share ownership restrictions apply
Physiotherapists (CPO): CPO approval required; eligible shareholders defined by CPO
RMTs (CMTO): CMTO permits incorporation with compliant share structure
Acupuncturists/TCM (CTCMPAO): CTCMPAO approval process applies
Naturopathic Doctors (CONO): CONO approval required; share ownership rules apply

The specific requirements vary by college. Incorporating without proper college approval is a compliance violation. Always work with an accountant and lawyer who understand your regulatory requirements.

What This Means for Your Clinic

Whether incorporation is worthwhile depends on individual income, how much is drawn personally versus retained, and personal goals — it is best modelled with a CPA against your specific numbers.
