Key Highlights

• Concessional contributions are made from before-tax income and taxed at 15% within the super fund

• Non-concessional contributions come from after-tax income and are not subject to additional tax unless caps are exceeded

• Exceeding contribution caps results in higher tax rates on amounts above the limit

• Personal injury payments and downsizer contributions have specific exclusions from contribution caps

Australian Superannuation is typically taxed at lower rates compared to most Personal Income and investments. However, the tax system applies specific thresholds called contribution caps to manage how much you can contribute within favourable tax treatment. The amount of tax you pay on super contributions depends on the contribution source, whether you have exceeded the applicable caps, and your income level. Understanding these mechanics is essential for effective retirement planning.

Concessional Contributions Explained

Concessional contributions are contributions made from income that has not yet been taxed, commonly referred to as before-tax contributions. These include employer superannuation guarantee contributions, salary sacrificed amounts, personal contributions claimed as tax deductions, and paid parental leave superannuation contributions. When you make concessional contributions, they are taxed within your super fund at a consistent rate of 15%, which is typically lower than your personal marginal tax rate. This creates a tax advantage that encourages retirement savings. All your concessional contributions across multiple super funds are combined for cap calculation purposes.

Non-Concessional Contributions Defined

Non-concessional contributions are payments made from income that has already been taxed, or after-tax contributions. These include personal contributions you have not claimed as tax deductions, contributions from your current spouse, and retirement benefits re-contributed to super. Unlike concessional contributions, non-concessional contributions are not subject to additional tax provided you remain within the specified cap. However, exceeding the cap results in taxation at significantly higher rates. Many types of contributions fall into this category, and it is important to track these across all your super funds.

Special Contribution Exclusions

Certain contributions are excluded from non-concessional contribution cap calculations. Personal injury payments receive special treatment, allowing the compensation portion to be excluded when you make a specific election. Downsizer contributions from home sale proceeds also receive exemption. Capital Gains Tax amounts arising from small Business exemptions can be excluded through election. COVID-19 early release superannuation amounts that are re-contributed are similarly excluded. These exclusions require you to formally notify your super fund using appropriate forms before or when making the contribution.

Conclusion

Concessional and non-concessional contributions form the foundation of how superannuation taxation operates. By understanding the differences between before-tax and after-tax contributions, and how contribution caps function, you can structure your retirement savings efficiently. Keeping track of both types across all your super accounts ensures you remain within caps and maximise the tax benefits available to you.
