Protecting Limited Liability: Separating Personal Finances from Your Corporation — CPA Firm Near You, Montreal

Introduction

Many small business owners in Quebec believe that simply incorporating provides full protection from personal liability. But limited liability only works if you respect the legal separation between yourself and your corporation. Mixing personal and business finances, failing to maintain records, or using the corporation’s bank account improperly can cause courts or tax authorities to “pierce the corporate veil,” making you personally responsible for corporate debts. This guide explains how to properly separate personal and corporate finances to protect limited liability, reduce audit risk, and maintain tax compliance.

Legal and Regulatory Framework

Under the Quebec Business Corporations Act (QBCA), Canada Business Corporations Act (CBCA), and the Income Tax Act, a corporation is a separate legal and tax entity. For limited liability to apply, owners must maintain proper corporate records, respect corporate formalities, operate through corporate accounts, issue proper resolutions, and avoid using the corporation for personal purposes. CRA requires accurate books, separate bank accounts, shareholder loan tracking, documented dividends or salaries, and compliance with GST/QST and payroll rules. Failure to keep finances separate may create taxable shareholder benefits or reclassification of income.

Key Court Decisions

Courts have repeatedly held that shareholders who mix personal and corporate finances risk losing liability protection. Judges have allowed creditors to pursue personal assets when corporate formalities were ignored. In tax cases, courts confirmed that personal expenses paid through the corporation become taxable shareholder benefits. Several decisions show that incomplete minute books, undocumented loans, and mixed accounts invalidate the corporation’s separate legal identity. Courts emphasize that maintaining proper financial separation is essential.

Why CRA and Revenu Québec Scrutinize Financial Separation

Financial mixing is one of the most common triggers for audits. CRA examines whether owners use corporate funds for personal purchases, whether shareholder loans comply with Section 15(2) rules, whether dividends or salaries were properly declared, and whether expenses are business-related. Revenu Québec reviews GST/QST claims, shareholder benefits, and compliance with QBCA requirements. Corporations that mix finances often face reassessments, denied deductions, and penalties.

How to Properly Separate Personal and Corporate Finances

Use a dedicated corporate bank account

All business income and expenses must flow through the corporation’s account.

Pay yourself through salary or dividends

Compensation must be formally recorded and documented.

Track shareholder loans accurately

Any withdrawals must be repaid or cleared with dividends or bonuses.

Avoid paying personal expenses through the corporation

Doing so triggers taxable benefits.

Keep accounting records separate

Personal and business bookkeeping must be distinct and documented.

Maintain a complete minute book

All dividends, salaries, borrowing, and major decisions must be documented.

Update GST/QST, payroll, and tax accounts

Corporate accounts must reflect corporate—not personal—activity.
