To switch to the Access ATO Gateway:
We recommend that all users log out of HandiTax for the changes to take effect.
One user must open HandiTax via HSoft\Apps\HTxx.exe or a HandiTax desktop shortcut - i.e. not via Practice Manager Contact.
Go to Options, Set ATO Credentials.
Select Access ATO Gateway, enter the keystore password, and click OK.
Restart HandiTax and attempt a connecting by completing a lodgment or prefill.
Other users can now log in.
If you receive a rejection error: 'AUTH.006', you are required to register the Software ID with the ATO, see How do I notify the ATO of my Software ID? for more information.
