Get a GST/HST access code – File your GST/HST return
You may be looking for:
The GST/HST access code is a 4-digit code required for some GST/HST filing methods. It is a personal security key that authenticates you when you are not signed into a CRA account. You should not give your access code to anyone unauthorized.
Your GST/HST access code stays the same for every filing period unless you change it.
Filing without an access code
You do not need an access code if you are filing:
- In your CRA account (My Business Account or Represent a Client)
- Through a participating Canadian financial institution
- By mail
When you need an access code
You do need an access code only if you are filing:
- Online using the GST/HST NETFILE form (outside of a CRA account)
- Using third-party accounting software (GST/HST Internet File Transfer)
- Over the phone using GST/HST TELEFILE
A representative that is legally authorized to sign the paper copy of your GST/HST return may use your access code to file your return if they are using a method that requires an access code.
How to get or change an access code
If you are a non-resident, we send you an access code by mail when you register for the GST/HST. You will also get an access code if you receive your GST/HST filing package by mail. This access code is located near the top of the letter in a box.
You can get a new access code online or by phone.
