Deductions are amounts taken from an employee’s gross pay before net pay is calculated.
What are deductions?
Deductions are amounts withheld from gross pay for mandatory or authorised purposes. In Australia, mandatory deductions typically include income tax, while other deductions may be voluntary, such as salary sacrifice arrangements, union fees or employee contributions to benefits.
From a payroll and compliance perspective, deductions must be lawful, correctly calculated and clearly authorised. Incorrect or unauthorised deductions can lead to disputes, underpayments or compliance action, which makes accurate setup and record‑keeping essential.
