Sometimes, the CRA identification number doesn’t match the NETFILE Québec number, which can cause error T3BBAS07.

To resolve this, follow these steps:

  2. Select TP1 Internet under T1.
  3. Enter the NETFILE Québec number in both fields: CRA Preparer number and NETFILE QC number.
  4. Select OK.

The error should be resolved.
