Corporate Tax Deductions Available to Incorporated Doctors in Alberta

Incorporating a medical practice can create planning opportunities, but only if the corporation’s expenses are properly deducted and documented. This guide explains the main deductions available to physicians practising through a professional corporation in Alberta. It separates federal Canada Revenue Agency (CRA) rules from Alberta-specific points and flags figures you should verify before relying on them.

Understanding the Corporate Structure for Alberta Physicians

In Alberta, physicians generally practise through a professional corporation. It is incorporated under provincial corporate law, and the physician must hold a corporate permit from the CPSA. Rules about who may hold shares are set by the profession’s regulator, so confirm them with the CPSA and your lawyer. This article assumes a Canadian-controlled private corporation (CCPC) that is a professional corporation with a December 31 or other fiscal year-end.

The main tax feature is the corporate rate. Active business income is taxed at a lower rate than the top personal rate, which allows income to be retained for investing or for later withdrawal. The deductions below determine how much income is taxed in the corporation in the first place.

Federal Versus Alberta Rules: What Applies Where

• Federal (CRA): The Income Tax Act governs which expenses are deductible, capital cost allowance (CCA), shareholder benefits, payroll withholdings, CPP, EI, and GST. The CRA also administers the federal small business deduction.
• Alberta: Alberta administers its own corporate income tax. Corporations generally file an Alberta corporate return (AT1) with Alberta Tax and Revenue Administration in addition to the federal T2. Alberta has its own corporate rates (verify), but it largely follows federal rules for what is deductible.
• No Alberta PST or HST: Alberta has no provincial sales tax. Only the 5% federal GST applies.
• CPP and EI are federal: There are no Alberta-specific CPP or EI rules, unlike Quebec. Alberta employers also have workers’ compensation obligations through WCB-Alberta, so confirm whether coverage applies to your clinic.

Verify before relying on them: At the time of writing, the combined small business rate in Alberta is generally cited as 11% (9% federal after the small business deduction plus 2% Alberta) on the first $500,000 of active business income. The general rate is generally cited as 23% (15% federal plus 8% Alberta). Confirm these with the CRA and Alberta Tax and Revenue Administration.
