Banking for Incorporated Businesses in Canada 2025

Updated March 2025 · 10 min read

Once you incorporate a business in Canada, your company becomes a separate legal entity from you personally. This has profound implications for banking — the corporation must have its own accounts, its own tax obligations, and its own financial records entirely separate from your personal finances. This guide covers everything incorporated Canadian businesses need to know about banking and financial management.

Opening a Corporate Bank Account

To open a corporate bank account in Canada, you'll need:

• Certificate of Incorporation (federal or provincial)
• Articles of Incorporation
• Corporate registry search confirming current directors (some banks require this)
• Government-issued photo ID for all directors and authorized signatories
• Corporate resolution or minutes authorizing the account opening and naming signing officers
• Business Number (BN) from the CRA

Most major banks require an in-person meeting for corporate account opening. Bring all documents in original form where possible. The process typically takes 1–2 business days once documents are verified.

Corporate Signing Authority

A corporate bank account requires defined signing authority — who is permitted to authorize transactions, sign cheques, and access online banking. Common structures:

• Solo signatory: One individual (usually the sole director/officer) can authorize all transactions independently. Simple for one-person corporations.
• Dual signing: Two signatures required for transactions over a threshold amount. Common in multi-owner corporations for control purposes.
• Full board resolution: Major transactions (opening credit facilities, purchasing real estate) may require a formal corporate resolution passed at a board meeting.

Your banking resolution — the corporate document that establishes signing authority — should be reviewed by your lawyer when setting up the account and updated whenever signing officers change.

Corporate Tax Obligations

Incorporated businesses in Canada have distinct tax obligations from individuals:

T2 Corporate Tax Return

All Canadian corporations must file a T2 corporate income tax return annually. The T2 is due 6 months after your fiscal year-end. However, any taxes owing are due 2–3 months after year-end (2 months for most CCPCs, 3 months if you qualify for the extended deadline). Filing late results in penalties of 5% of the outstanding balance plus 1% per month up to 12 months.

Federal Small Business Tax Rate

Canadian-controlled private corporations (CCPCs) benefit from the small business deduction, reducing the federal corporate tax rate to 9% on the first $500,000 of active business income annually. This is one of the lowest effective corporate tax rates in the G7. Above $500,000, the general federal corporate rate of 15% applies.

Provincial Corporate Tax

Provincial corporate tax rates add to the federal rate. Combined federal + provincial rates on the first $500,000 of active business income (the "small business rate") vary by province:

• Ontario: ~12.2% combined
• British Columbia: ~11%
• Alberta: ~11%
• Quebec: ~14.5%
• Nova Scotia: ~14%

Corporate Tax Installments

If your corporation's federal or provincial tax owing exceeds $3,000, you must pay monthly tax installments throughout the year. Most small incorporated businesses pay quarterly installments. Your accountant will help you calculate the required installments based on prior-year taxes and current-year projections.

Paying Yourself from a Corporation

As an owner-operator of a Canadian corporation, you can extract money in two primary ways:

Salary

The corporation pays you a salary as an employee. The corporation deducts CPP employer contributions and income tax withholding. The salary is a deductible expense to the corporation, reducing its taxable income. You report the salary as employment income on your personal T1 return. Salary creates RRSP contribution room.

Dividends

The corporation pays retained earnings to shareholders as dividends. Dividends are paid from after-tax corporate income. They're taxed personally at reduced "eligible" or "ineligible" dividend tax rates, which account for the corporate tax already paid. Dividends do not create RRSP room and are not subject to CPP.

The optimal mix of salary and dividends is a key tax planning decision — work with a CPA who understands owner-manager compensation to optimize your annual structure.

Director's Loans and Shareholder Loans

A shareholder loan arises when you take money from the corporation without declaring it as salary or dividends. The CRA has strict rules: shareholder loans must be repaid within one year of the corporation's fiscal year-end in which they arose, or they're included in the shareholder's personal income. Keeping shareholder loan balances low and properly documented is essential to avoid CRA reassessments.

Corporate Banking Best Practices

• Never commingle personal and corporate funds — not even temporarily
• Pay yourself through declared salary or dividends, not ad hoc withdrawals
• Maintain a separate savings account for corporate tax reserves — set aside 15% of revenue
• Set up an HST/GST clearing account to hold collected tax until remittance
• Reconcile accounts monthly and close your books quarterly
• Have your accountant review quarterly financial statements, not just at year-end
• Review signing authority and bank access annually, especially if ownership or management changes

Multiple Corporate Bank Accounts

Growing corporations often benefit from multiple accounts:

• Operating account: Day-to-day transactions — revenue, payroll, supplier payments
• Tax reserve account: Hold corporate tax installments and HST/GST collected
• Payroll account: Some businesses run payroll from a dedicated account for clarity
• USD account: If billing US clients in US dollars, avoid FX conversion costs with a dedicated USD account
