Opening a business bank account — what you need and why it matters

Opening the corporate bank account is one of the first tasks after incorporating and one of the most often deferred, because the personal account already works. Deferring it has a hidden cost: every week the corporation runs through a personal account adds transactions someone must later separate, and the corporation is not acting as a separate entity.

Set the account up so the bookkeeping can use it from the first transaction and the year-end costs less. An email enquiry covers what the bank will ask for.

Why a corporation genuinely needs its own account

The strongest reason is the one owners think about least. Incorporating creates a separate legal person, and limited liability depends on that separation being real in practice rather than only on paper. A corporation whose money lives in its owner’s personal account is not obviously distinct from its owner, and that is the argument you never want to have to answer.

The second reason is practical. Every downstream process assumes a dedicated account. Reconciliation proves the corporation’s cash against the corporation’s statement. The shareholder loan account only means something if there is a boundary for money to cross. Schedule 100 of the T2 reports a cash balance that has to correspond to something. Mixed accounts break all three at once, which is why separating business and personal money is the habit with the largest payoff.

Third, administration. GST/HST and corporate tax refunds and CRA direct deposit pay to a business account; payroll remittances and pre-authorized debits run from one. A cheque made out to a corporation cannot go into a personal account.

What you need to open a corporate bank account

Requirements vary between institutions, but the pattern is consistent, because banks are verifying that the entity exists and that the people opening the account are entitled to act for it. Expect to be asked for:

• The incorporation documents — certificate and articles of incorporation, federal or provincial. Have the exact legal name to hand, including any numbered-company form.
• Proof of who controls the corporation — typically the director and officer register and the shareholder register from your minute book, plus a banking resolution authorizing who may sign.
• Government photo identification for each signing authority and, under beneficial-ownership rules, information about individuals holding significant ownership.
• The business number issued by the CRA, and often the program account numbers if you already have them.
• A business address and a description of the activity, which the bank uses for its own risk classification.

If the corporation trades under a name different from its legal name, bring the registration for that operating name too. That is what allows the bank to accept cheques payable to it.

Get the business number first

1. Incorporate, and have the exact legal name to hand, including any numbered-company form.
2. Obtain the business number and the program accounts you need — payroll, GST/HST, information returns — before you book the bank.
3. Gather what the bank will ask for: the certificate and articles, the director, officer and shareholder registers, a banking resolution, and photo identification for each signing authority.
4. Open the account in the corporation’s legal name, set up so the bookkeeping can use it from the first transaction.

The sequence that saves a second appointment is: incorporate, obtain the business number and the program accounts you need, then open the account. A federally incorporated company usually receives its business number and corporation income tax account as part of incorporation, and several provinces do the same. Which additional accounts you need — payroll, GST/HST, information returns — depends on your activities, and the structure is explained in the guide to business numbers and CRA program accounts. For anyone asking how to start an incorporated bank account Canada banks will accept, the order is incorporate, get the business number, then open the account.

How to set it up so the bookkeeping works

Open a chequing account and corporate credit card in the corporation’s name together. Most commingling happens on cards, because the wrong card is easier to grab than the wrong account.

Open a second savings account at the same bank as your tax and GST/HST reserve. It is free, hides the money from the operating balance, and is behind almost every business that never has a remittance problem. Then link the accounts to your bookkeeping software from day one; see the guide to QuickBooks and Xero in Canada.

While you are at it, set up CRA direct deposit and pre-authorized debit from the business account, and register online banking with the same signing authorities. Then reconcile from the first month; the guide to bank reconciliation explains why that first month matters most.

Common mistakes

Using a personal account “just until things pick up” is the commonest mistake, and it creates the untangling the account was meant to avoid. A personal account with a business label is still personal: cheques to the corporation may be refused. Two operating accounts with no rule on which pays what recreate the ambiguity. And a former signing authority left on the account is an avoidable exposure.

Opening the account after a BC incorporation

In the Fraser Valley the documents the bank asks for are the BC registry ones: the certificate of incorporation, the notice of articles and the incorporation application, plus the CRA business number once it is issued. A Langley or Abbotsford corporation opening its first account usually has all of them within a day of incorporating; the delay is normally the business number.

The bottom line

The corporate account is the boundary that makes the corporation real. Open it in the legal name with the incorporation documents and business number, add a card and a reserve account, and run all business income and expenses through it from day one. Reconciliation, the shareholder loan, the T2 and any CRA review all get easier.

Just incorporated? The bank account is step one of about nine

Opening the account is one of the first and easier tasks. Others follow: choosing a year-end, deciding whether you need a GST number yet, setting up payroll before the first pay run. Order affects cost; The first 90 days sets them out with dates.
