Superannuation compliance is one of the most critical payroll responsibilities for Australian employers. Yet, despite its importance, superannuation underpayments remain a widespread issue, leading to financial penalties, back payments, and reputational damage.
With the Australian Taxation Office (ATO) increasing its scrutiny and further super guarantee (SG) rate increases on the horizon, businesses must take a proactive approach to compliance. Preventing errors before they occur not only safeguards employees’ entitlements but also protects businesses from costly consequences.
In this article, we’ll explore the common causes of superannuation underpayments, how to prevent them, and the key steps employers should take to stay ahead of regulatory changes.
Why Do Superannuation Underpayments Occur?
Superannuation underpayments can arise from various payroll and compliance errors, often due to misunderstandings or outdated processes. Some of the most common causes include:
- Incorrect calculation of ordinary time earnings (OTE): The SG is generally based on OTE, but confusion over what qualifies—such as certain allowances and bonuses—can lead to underpayments.
- Failure to update payroll systems for rate changes: With SG rates increasing incrementally, outdated payroll settings can result in ongoing miscalculations.
- Missed super payments for contractors: Some businesses mistakenly assume that super only applies to employees. However, under the ‘deemed employee’ rules, certain contractors are also entitled to super contributions.
- Late or missed payments: Super must be paid at least quarterly. Late payments not only attract penalties but also become non-deductible for tax purposes.
- Payroll system errors: Incorrect settings, data entry mistakes, and integration issues can all lead to inadvertent underpayments.
