When you decide to close your business and no longer need your business number (BN), you have to fill in certain forms before the accounts can be closed. If your business is registered in Ontario, go to Registered in Ontario.

Each business account has its own procedures, such as how to meet filing obligations and make payments.

Payroll

Before closing your payroll account, you must:

• remit all payroll source deductions (to learn more, go to When to remit (pay))
• calculate the pension adjustment that applies to your former employees who accrued benefits for the year under your registered pension plan or deferred profit-sharing plan (to learn more, go to Pension Adjustment (PA))
• file your final payroll information returns (to learn more, go to When to file information returns)
• give copies of the T4 or T4A slips to your former employees or recipients (to learn more, go to Distribute the slips)

GST/HST

For more information, go to Open or manage an account – Close.

Corporate income tax

When you want to permanently dissolve your corporation, you should send an application for dissolution to the government body that governs the affairs of your corporation.

Once the corporation has been dissolved, you should consult Form RC145, Request to Close Business Number Program Accounts, to determine whether you need to fill in that form and send a copy of the articles of dissolution to the CRA. Otherwise, the CRA considers that the corporation still exists and it will have to file a return even if there is no tax payable.
