What is back pay?

Back pay is the recovery of wages or entitlements an employee was underpaid, usually subject to a six-year time limit.

Back pay is money owed to an employee for wages or entitlements they should have been paid but were not — for example because they were paid below the award rate, missed penalty rates or allowances, or had super underpaid. The employer is required to pay the shortfall.

Underpaid employees can recover back pay through the Fair Work Ombudsman or by court action. There is generally a six-year time limit on recovering underpayments under the Fair Work Act 2009, so it is best to raise a claim as soon as the underpayment is identified.
