I guess there's more than 1 way looking at it. My opinion is if you do your tax yearly and know it's up to date, I believe there's no reason not to decline the automatic assessment and file your own return.

It's true. My automatic processing sms was for a payment of R3300 but I didn't accept as I know it must be much more, I filed my own and there was a difference of R11000.
