Do you need a separate bank account for your business in Québec?

Short answer: if you're incorporated, in practice yes: the corporation is a separate legal person, and its money should stay in its own account. If you're a sole proprietor, no law forces you to open one, but we strongly recommend it. Mixing personal and business transactions makes your bookkeeping slower, your expenses harder to prove and an audit more painful.

Sole proprietor: why bother?

As a sole proprietor, the business and you are the same taxpayer. Your profit goes on your own T1 and TP-1. Still, a separate account (and ideally a separate credit card) changes your day-to-day:

  • Cleaner books. Every transaction in the account is a business one. No sorting groceries from supplies.
  • Easier to prove. If the CRA or Revenu Québec asks about an expense, the statement and the receipt line up.
  • GST/QST is easier to track. The taxes you collect and pay all flow through one place.
  • A clear picture. You see what the business actually earns, separate from your household spending.

A plain personal chequing account used only for the business can do the job at the start. A true business account becomes worth it once clients pay you under your business name.

Corporation: separate by definition

A corporation owns its own money. Paying personal bills from the company account, or depositing company revenue into your personal account, blurs that line and creates tax issues.

  • Revenue goes into the company's account. Always, including e-transfers.
  • Expenses are paid by the company when they are company expenses.
  • Anything else is a transaction with you, the shareholder, and has to be recorded as one.

How the shareholder loan account works

The shareholder loan account (often called "due to/from shareholder") tracks money between you and your company.

  • You pay a company expense personally: the company owes you. It can repay you later with no tax cost.
  • The company pays a personal expense for you: you owe the company.

The second situation has a deadline. Under subsection 15(2) of the Income Tax Act, a loan from a corporation to a shareholder (or to a person connected to one) can be added to that person's income. There are a few exceptions. The one that matters most for owner-managers is subsection 15(2.6), which applies when the loan is repaid within one year after the end of the corporation's tax year in which it was made, as long as the repayment isn't part of a series of loans and repayments.

Example

Your company has a December 31 year-end. In March 2026, it pays $3,000 of your personal expenses.

  1. The $3,000 is recorded as owed by you to the company.
  2. To fall under the one-year exception, you repay it by December 31, 2027.
  3. If it's still unpaid then, the $3,000 can be included in your income for 2026, unless it's dealt with another way (for example a salary or dividend, which has its own tax treatment).

Setting it up right

  1. Open the account in the exact legal name of the business (or corporation).
  2. Get a business credit card for expenses.
  3. Pay yourself by transfer, never by paying personal bills from the business account.
  4. Connect the account to your bookkeeping software and reconcile it every month.

Frequently asked questions

Is a separate bank account mandatory for a sole proprietor in Québec?

No law requires it for a sole proprietor, but you must keep adequate records. A dedicated account makes that much easier and makes your expenses easier to support if you are reviewed.

What is a shareholder loan account?

It is the account in your corporation’s books that tracks money between you and the company: what the company owes you and what you owe the company.

What happens if I owe my corporation money at year-end?

Under subsection 15(2) of the Income Tax Act, the amount can be added to your income unless it is repaid within one year after the end of the corporation’s tax year in which the loan was made, and the repayment is not part of a series of loans and repayments.
