The Superannuation Guarantee (SG) is Australia's mandatory employer retirement savings system. Employers are legally required to contribute a percentage of an employee's ordinary time earnings (OTE) into a complying superannuation fund on their behalf. The SG rate has been progressively increasing and stands at 11% from 1 July 2023, rising to 11.5% on 1 July 2024, and reaching the legislated 12% on 1 July 2025. OTE includes regular wages, commissions, shift loadings, and most allowances, but excludes overtime payments. Contributions are taxed at a concessional rate of 15% inside the fund, making super a highly tax-efficient savings vehicle for most workers. There are two types of contribution caps: the concessional (before-tax) contributions cap of $27,500 per year (which includes SG and salary sacrifice amounts), and the non-concessional (after-tax) cap of $110,000 per year. Low-income earners may receive the Low Income Super Tax Offset (LISTO) of up to $500, which effectively refunds the 15% contributions tax for those earning under $37,000. Understanding how the super guarantee works helps employees verify their entitlements and plan for retirement, as even small shortfalls compounded over decades can significantly reduce retirement savings.
SG Contribution = OTE × SG Rate; Concessional Tax = SG Contribution × 0.15; Net Super Added = SG Contribution − Concessional Tax
- 1Determine the employee's Ordinary Time Earnings (OTE) for the quarter — this includes base salary, commissions, shift loadings, and allowances but excludes overtime.
- 2Apply the current SG rate (11% in 2023-24, 11.5% in 2024-25, 12% from 2025-26) to calculate the required employer contribution amount.
- 3The employer must pay the SG contribution into the employee's nominated super fund by the quarterly due dates: 28 October, 28 January, 28 April, and 28 July.
- 4The super fund deducts 15% contributions tax on all concessional contributions (employer SG plus any salary sacrifice amounts), which is reported as a deduction on the fund's annual return.
- 5Check whether the total concessional contributions (SG + salary sacrifice) exceed the $27,500 annual cap. Excess concessional contributions are included in assessable income and taxed at the marginal rate plus a charge.
- 6Low-income earners (below $37,000) may be eligible for the Low Income Super Tax Offset (LISTO) — up to $500 — effectively making their contributions tax-free.
- 7Employees can view their super balance, contributions received, and investment earnings via their fund's online portal or through myGov linked to the ATO.
Contribution is below the $27,500 concessional cap.
The employer must pay $9,200 into the employee's super fund. After 15% contributions tax ($1,380), $7,820 is added to the account balance. This grows tax-effectively inside the fund.
The $500 excess is included in taxable income and taxed at marginal rate plus 2% charge.
High earners must monitor concessional contributions carefully. Total concessional contributions are $28,000, exceeding the $27,500 cap by $500. The ATO issues an excess concessional contributions determination.
LISTO refunds the full 15% tax for earners under $37,000.
The $552 in contributions tax is refunded to the super fund via LISTO, meaning the full $3,680 employer contribution effectively goes into the account. The LISTO is capped at $500, so the refund here is $500 as the tax exceeds the cap.
Even part-time workers are entitled to SG on all OTE.
Employers pay SG quarterly. For $6,500 OTE, the employer owes $747.50 per quarter ($2,990/year). If the employer pays late, the Superannuation Guarantee Charge (SGC) applies, which is higher than the standard SG.

What is Ordinary Time Earnings (OTE)?
OTE is the amount you earn for your ordinary hours of work. It includes base salary, commissions, shift loadings, and most allowances. It excludes overtime payments, expense reimbursements, and certain bonuses paid irregularly. The ATO provides a checklist to help employers determine what counts as OTE. This is particularly important in the context of super guarantee calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise super guarantee calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
When does the SG rate reach 12%?
The SG rate increases incrementally: 11% (2023-24), 11.5% (2024-25), and 12% from 1 July 2025. This was legislated by the Superannuation Guarantee (Administration) Amendment Act. This is particularly important in the context of super guarantee calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise super guarantee calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What happens if my employer doesn't pay my super?
Employers who fail to pay super on time must pay the Superannuation Guarantee Charge (SGC) to the ATO. The SGC includes the unpaid SG amount, a nominal interest component (10% p.a.), and an administration fee. Employees can report unpaid super to the ATO via the online tip-off form. This is particularly important in the context of super guarantee calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise super guarantee calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the concessional contributions cap?
The concessional contributions cap is $27,500 per financial year (2023-24 and 2024-25). It covers all before-tax contributions including employer SG, salary sacrifice, and personal deductible contributions. Contributions above this cap are included in your assessable income and taxed at your marginal rate, less a 15% offset. This is particularly important in the context of super guarantee calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise super guarantee calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the LISTO?
The Low Income Super Tax Offset (LISTO) is a government payment of up to $500 for individuals with income up to $37,000. It effectively refunds the 15% contributions tax paid by the super fund on concessional contributions, ensuring low-income earners don't pay more tax on super than on their regular income.
Can I salary sacrifice to reduce my taxable income?
Yes. Salary sacrifice contributions are made from pre-tax income and taxed at 15% inside the fund, which is lower than most people's marginal tax rate. However, salary sacrifice plus employer SG must not exceed the $27,500 concessional cap or the excess will be taxed at your marginal rate. This is particularly important in the context of super guarantee calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise super guarantee calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Is SG paid on bonuses?
SG is paid on OTE, and whether a bonus qualifies as OTE depends on its nature. Regular performance bonuses paid for ordinary work are typically OTE. Discretionary or irregular bonuses may not be OTE. Employers should review each bonus type against ATO guidelines. This is particularly important in the context of super guarantee calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise super guarantee calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the Division 293 tax?
Division 293 tax applies an additional 15% tax on concessional contributions for individuals whose income plus concessional contributions exceed $250,000. This effectively raises the contributions tax rate for high earners from 15% to 30%, reducing the super tax advantage compared to paying income tax at the top marginal rate of 45%.
Pro Tip
Use the ATO's Super Guarantee eligibility checker to confirm whether each worker in your business is entitled to SG. Always cross-check OTE components carefully — getting this wrong in either direction leads to either underpayment (ATO penalty) or overpayment that's difficult to recover.
