Register for a GST/HST account

Generally, you will need to register for your business number (BN) before you can register for a GST/HST account.

You may register for a BN by using the online service at Business Registration Online (BRO). This is the quickest way to register for a BN. Once you have obtained your BN, you can then continue in the same session to register for a GST/HST account.

Note

When you register for a BN using BRO, you will be provided with a new nine-digit BN. You must retain this new BN for your own records and future interactions with the CRA.

If you already have a BN and only need to register for a GST/HST account, you can still use the following button.

For other methods of registration, see How to register for a business number or Canada Revenue Agency program accounts.

Once you have obtained your BN, read the information below on opening a GST/HST account.

If you are a non-resident and want to register for a GST/HST account, see Guide RC4027, Doing Business in Canada – GST/HST Information for Non-Residents.
