According to Canada Revenue Agency (CRA), for the 2022 tax year, prior to filing your tax return electronically with NETFILE you will be asked to enter an Access code. While this access code is not mandatory, if you do not enter your Access code, you will not be able to use any information from your 2022 tax return when confirming your identity with the CRA. You will have to rely on other information for authentication purposes.
This code does not apply to you if you are filing your tax return for the first time.
For more information, please see TurboTax webpage: NETFILE Access Code
