How Do I Calculate Superannuation?

In Short

  • Superannuation Contributions: Employers must contribute 11.5% of an employee’s ordinary time earnings (OTE) to their superannuation, increasing to 12% from 1 July 2025.
  • Ordinary Time Earnings (OTE): OTE includes regular earnings such as commissions, shift loadings, allowances, and bonuses, but excludes overtime payments.
  • Payment Deadlines: Super contributions are due quarterly, with deadlines on 28 January, 28 April, 28 July, and 28 October.

Tips for Businesses

Ensure you calculate super contributions accurately by understanding what constitutes OTE. Keep track of quarterly deadlines to avoid penalties. Regularly review employee earnings and stay updated on legislative changes to maintain compliance. Utilise tools like the ATO’s Super Contribution Calculator for assistance.

As an employer in Australia, you are responsible for ensuring that your employees receive their rightful superannuation (super) contributions, which form a critical part of their retirement savings. The Superannuation Guarantee (SG) laws require you to make regular payments to your employees’ super funds. Failing to meet these obligations can lead to significant financial penalties and legal consequences, so understanding how much super to pay and when to pay it is essential.

The laws surrounding super contributions can appear complex. Still, with a solid grasp of the rules and an effective process for managing super payments, you can stay compliant and secure your employees’ financial futures. This article will guide you through the essentials of determining how much super to pay, what income qualifies for super contributions, and the importance of adhering to deadlines.

Superannuation Guarantee Contribution Rate

The SG is the minimum amount of super you must pay eligible employees. Currently, the SG contribution rate is set at 11.5% of your employee’s ordinary time earnings (OTE), which will increase to 12% starting 1 July 2025.

This percentage is calculated based on an employee’s OTE, which includes most of their regular earnings. You are required to pay this contribution for every eligible employee, and it applies whether they are full-time, part-time, or casual. The SG also applies to contractors in certain situations.

Understanding the SG payable amount is crucial because it forms the foundation of your super obligations. If you underpay your employees’ super, even accidentally, you may be liable for the Super Guarantee Charge (SGC), which is a financial and administrative burden.

Ordinary Time Earnings

To calculate the correct SG contributions, you need to understand the concept of OTE. OTE refers to the amount your employees earn for their ordinary work hours. It includes:

  • certain overtime payments;
  • shift loadings;
  • annual leave loadings;
  • bonuses;
  • certain allowances; and
  • commissions.

If your employees work overtime beyond the ordinary hours outlined in their employment agreement, you do not include these amounts in their OTE or pay super on them.

However, you must include overtime payments in OTE if the ordinary work hours are not specified in an award or agreement, or if overtime hours are not separated from other hours.

To ensure compliance, it is important to understand what counts as OTE in your business context. Miscalculating your employees’ OTE can result in paying too much or too little super, which can have consequences.

The Australian Taxation Office (ATO) provides a helpful tool called the Super Contribution Calculator to assist you in determining the correct amount of super to pay.

Maximum Contribution Base

While you are required to pay super on your employees’ OTE, there is a cap on the earnings you need to consider for SG contributions. This is known as the maximum contribution base. The maximum contribution base for the 2024-2025 financial year is $65,070 per quarter.

This means that if an employee earns more than $65,070 in OTE in a single quarter, you are only required to make super contributions on the first $65,070. Any amount above this threshold is not subject to the SG contribution requirement, although you can contribute more if you wish. Going over this threshold may mean the employee is subject to additional tax.

The maximum contribution base is adjusted annually, so it is essential to stay informed about the latest figures to ensure that you are not underpaying or overpaying your super contributions.

Deadlines for SG Contributions

SG contributions must be paid at least quarterly, with deadlines on the 28th day of the month following the end of each quarter. These deadlines are:

  • 28 January for the October to December quarter;
  • 28 April for the January to March quarter;
  • 28 July for the April to June quarter; and
  • 28 October for the July to September quarter.

It is crucial to meet these deadlines, as missing a payment or paying late can lead to significant penalties under the SGC. The SGC is not just the unpaid super amount; it also includes a penalty of up to 200% of the unpaid SCG,  interest, and an administration fee. If you miss a deadline, you will need to lodge an SGC statement with the ATO and pay the charge, which is non-deductible for tax purposes.

From 1 July 2026, employers will be required to pay their employees’ superannuation in addition to their salary and wages.

Payments for Former Employees and Back Pay

Sometimes, you may need to make super contributions for employees who no longer work for you, especially in cases of back pay or outstanding payments. If these payments relate to OTE, you must still make the appropriate super contributions, even if the employee has left your company.

Moreover, this obligation also applies to back pay, which is any payment you make to employees after they have left your employment. If the back pay relates to periods when they were earning OTE, super contributions must be made on this amount.

To avoid non-compliance, accurate records of all payments and correct calculation of super contributions should be kept for at least five years.

Key Takeaway

Any employer in Australia must ensure that their employees receive the correct amount of superannuation. The current SG rate is 11.5% of OTE but will increase to 12% from 1 July 2025. Super contributions must be paid quarterly, and failure to meet deadlines can result in hefty penalties under the SGC.
