Because of the way my bank accounts are set up it is very easy to do a transfer from my account to the smsf and vice versa.
Tr 2010/01 says anything that increases the capital is a contribution.
The error may not be detected until end of year reconciliation. Surely, if a mistake like this if corrected when known cannot be a breach and/or contribution.
Apart from anything, the practice when making a contribution is to notify in writing that one is to be made.
The error can occur in the other direction, that the smsf transfers a large sum to the wrong trading account. Obviously, the member may not want this to be a pension payment particularly if it is a large amount. Can it be reversed with NO consequences.
