Understanding backpay exposure
What is backpay?
Money owed to employees when they have been underpaid. If wages, penalties, or allowances were incorrect, employers must make up the difference—often going back several years.
How far back?
Under Fair Work, underpayment claims can generally go back six years. Even small per-pay-period underpayments can compound into significant total liability over time.
What adds to the cost?
Beyond base underpayment, employers may owe superannuation (12%), interest on underpaid amounts, and administrative costs. Civil penalties may also apply.
Why backpay exposure matters
Financial impact
Even modest underpayments become significant across employees and years. A $20/week underpayment across 10 staff over 3 years exceeds $31,000 before super and penalties.
Self-disclosure benefits
Businesses that voluntarily identify and remediate underpayment are generally treated more favourably. The Fair Work Ombudsman has formal self-disclosure pathways.
Beyond backpay
Companies may face civil penalties up to $93,900 per contravention (2024 rates). Directors and managers can also be held personally liable in some circumstances.
How to reduce backpay exposure
Audit current pay practices
Review whether employees are being paid correctly under the relevant award, including base rates, penalties, and allowances.
Check award classification
Ensure employees are classified under the correct award and at the right level for their duties and experience.
Implement accurate time tracking
Use digital time and attendance systems to capture actual hours, breaks, and overtime for accurate pay calculations.
Consider self-disclosure
If underpayment is identified, consider self-disclosing to Fair Work Ombudsman for more favourable treatment.
Get professional advice
For significant exposure, consult an employment lawyer or workplace relations specialist to understand your options and obligations.
