Registration with Canada Revenue Agency (CRA)

Region: Ontario Answer # 0203

Most businesses are required to collect and remit federal taxes and will first need to register with Canada Revenue Agency (CRA) to do so. CRA assigns each business just one Business Number (BN) to simplify correspondence with them.


Applying for a Business Number (BN) with CRA

To apply for a Business Number you must fill out a form available from CRA. Once you are assigned a Business Number, you can use it as a reference number for collecting and remitting HST, import or export taxes, payroll deductions, and corporate income tax.

Other business taxes

There are other taxes and premiums that businesses pay that are administered by other government offices and do not use the Business Number assigned by CRA. These include Workplace Safety and Insurance and the Employer Health Tax.

Visit Canada Revenue Agency for more information regarding registration and applying for a Business Number.
