The bank said non-executive director fees will also be cut, by 20 per cent, in the current financial year.
AUSTRAC alleges CBA failed to provide on-time reports of 53,506 cash transactions of $10,000 or more and totalling $625m that were made through the bank's new Intelligent Deposit Machines (IDMs) from November, 2012 to September, 2015.
In a statement on Monday, CBA said a coding error, which occurred following a software update to its IDMs in late 2012, was responsible for the required Threshold Transaction Reports (TTRs) not being generated.
CBA said the fault was fixed within a month of it being discovered in 2015.
CBA is the parent of ASB Bank, which says it uses a different model of ATM and operating system from its parent company.
