What is a Pay adjustment?

Updated 20 Jan 2026 5 min read

A pay adjustment is a modification to an employee's wages to correct errors, account for missed payments, or reflect changes in circumstances. In Australia, pay adjustments may include underpayment corrections, overpayment recoveries, back-pay for award rate increases, or reconciliations for annualised salary arrangements.

Types of pay adjustments

Pay adjustments in Australia may be needed for various reasons. Understanding the different types helps ensure correct processing and Fair Work compliance.

Positive adjustments

  • Underpayment corrections
  • Back-pay for award increases
  • Missed shift payments
  • Salary reconciliation shortfalls

Negative adjustments

  • Overpayment recovery
  • Timesheet corrections
  • Advance repayments
  • Leave taken in advance

Processing underpayment adjustments

When underpayment is discovered, employers must calculate and pay the shortfall promptly:

Underpayment adjustment process

Identify period: Determine dates affected
Calculate shortfall: Correct rate minus paid rate × hours
Include super: Calculate additional super owing
Document: Record calculation method
Pay promptly: Process in next pay run
Itemise: Show clearly on payslip

Recovering overpayments

Overpayment recovery must follow Fair Work requirements. Employers cannot simply deduct the full amount without proper process.

Overpayment recovery rules

Under Fair Work, employers can recover genuine overpayments, but the deduction must be authorised in writing, cannot leave employees below award minimums, and must be reasonable in amount per pay period. Discuss a repayment plan with the employee and document the agreement.

Annual salary reconciliation adjustments

Many Modern Awards require annual reconciliation for employees on annualised salaries. If the salary paid was less than what the employee would have received under the award, a pay adjustment is required.

  • Calculate entitlement: Sum what employee would have earned under award (base + OT + penalties)
  • Compare to salary: Compare award entitlement to salary actually paid
  • Pay shortfall: If salary was less, pay the difference within 14 days
  • Document: Keep records of the reconciliation calculation

Common pay adjustment mistakes

Not adjusting superannuation

When back-paying ordinary time earnings, super must also be adjusted. Forgetting super creates additional compliance issues.

Unilateral overpayment deductions

Deducting overpayments without employee agreement or in amounts that take pay below award minimums violates Fair Work requirements.

Poor documentation

Not keeping records of why adjustments were made and how they were calculated. This creates audit issues and makes disputes harder to resolve.

Delaying corrections

Waiting to process underpayment adjustments. Once an error is discovered, it should be corrected in the next available pay run.

Key takeaways

Pay adjustments correct errors or account for changes in employee wages. They may be positive (underpayment corrections, back-pay) or negative (overpayment recovery). Processing adjustments correctly requires following Fair Work requirements, adjusting super where applicable, and maintaining clear documentation.

Minimising pay adjustments starts with accurate time tracking and correct award rate application. RosterElf's integrated system reduces errors by capturing actual hours worked and automatically applying correct rates for seamless payroll processing.
