EFILING (also referred to as e-filing)

Where an e@syfile (also referred to as easyfile) user have difficulties submitting returns or syncing data the following can be done to try and rectify this:

User rights
Please log into eFiling and go to Organisation (at the top of the page), then click on Rights groups (Left side of the page), then click on Manage groups and untick and tick the company again under manage payers then click on update.
There after go to Manage groups, click open and ensure that System Default is ticked and then update.

Then navigate to User (at the top of the page), then click on User (on the left side of the page), then click on Change Details and update rights, untick and tick the correct rights and the correct group (System default if the company is under that group).
Log out and in again on eFiling

Please use the username used to log onto eFiling together with your current eFiling password. Please also make sure that the password does not have the “$”,”%” and “ampersand” character.

Lastly, go on e@syfile and try again.
