Commonwealth Bank will hand over as much as $53.1 million it owes staff in unpaid entitlements.
The nation's biggest lender has been reviewing employee entitlements since 2017 and broadened the investigation the following year to include payroll.
CBA has so far notified or repaid approximately 41,000 current and former employees with $13.2 million of back pay plus interest, with a further $14.9 million to follow by the end of next week.
The bank on Friday said it expects to make a further $25 million in remaining payments by the end of the financial year.

"It is unacceptable that some of our people were not paid the correct entitlements," CBA chief executive Matt Comyn said in a release.
"This should never have happened and I apologise to anyone impacted by these past errors."
CBA - which reported a cash profit of $8.49 billion in FY19 - said the issue came to light after the bank commenced a review in 2017 of superannuation payable to part-time employees working additional hours at single-time rates.
The installation of a new payroll system in March 2018 helped the bank support a broader review of employee entitlements, with the first assessments made under that review and payments made to affected staff beginning in December last year.
Shares in CBA were 0.97 per cent higher at $80.49 after 30 minutes of trade on Friday.
