Making Tax Deductible Super Contributions

As of 2017, people under the age of 75 are able to claim an income tax deduction for personal superannuation contributions. The Australian taxation and superannuation systems provide notable benefits and concessions to people who contribute to their own super while they’re working. You must make tax deductible super contributions before June 30.

Contributions limits

Contributions limits, also known as “contributions caps”, limit the tax concessions you can claim — if you contribute too much, you might have to pay extra tax and an additional charge. The cap amount depends on your age, salary, and contributions.


  • Before-tax (concessional) contributions including employee contributions are capped at $25,000 per annum. This will change from July 1, 2021, to $27,500 per annum.
  • The tax payable on concessional contributions depends on your taxable income.
  • People with a taxable income (including super) of more than $250,000 a year or more pay 30%. 
  • After-tax contributions: Non-Concessional tax is payable on amounts up to $100,000 a year (or $300,000 over three years). Your total super balance must be less than $1.6 million. From July 1, 2021, this Non-Concessional cap increases to $110,000 (or $330,000 over three years).

How to contribute

If you want to boost your super, contributions can be done as an individual tax deductible super contribution or by salary sacrificing through your workplace (keeping your individual cap in mind).

Individual tax-deductible contributions

You are eligible to claim a deduction for personal super contributions if you meet the age restrictions, have given your fund a Notice of intent to claim or vary a deduction for personal contributions form (NAT 71121), and your fund has validated your notice of intent form and sent you an acknowledgement. You also need to ensure contributions to your fund was not a:


  • Commonwealth public sector super scheme in which you have a defined benefit.
  • Constitutionally protected fund (CPF) or other untaxed fund that would not include your contribution in its assessable income.
  • Super fund that notified us before the start of the income year that they elected to either treat all member contributions to the super fund as non-deductible or defined benefit interest within the fund as non-deductible.


Salary sacrificing

When you could ask your employer to pay some of your usual salary directly into your super account, instead of your bank account, this is salary sacrificing. Money paid into your super account by your employer is taxed at 15% — much lower than the usual rate.


For example, let’s say you earn $60,000 per year and your employer puts in 9.5% super ($5,700 per year). You decide you’d like to boost your super by salary sacrificing, and ask your employer to also pay a portion of your salary into your super rather than your bank account. Instead of the 34.5% tax you normally pay (income tax plus Medicare levy), this part of your income is only taxed at 15%.



With a contribution cap of 25,000/pa — remember, $5,700 has already been paid by your employer in this scenario — you can salary sacrifice up to $19,300 more per year at the 15% tax rate.


Two heads are better than one

One of the most powerful decisions you can make with your superannuation is whether to run your own self-managed super fund (SMSF) and whether to invest in property through it. Most people know it's possible to use super to buy property. Far fewer know how to do it well. The following seven tips are designed to help you make the right decisions. 1. You Can Borrow Money to Purchase Property in Superannuation. Don't have enough in your SMSF to buy an investment property outright? Since 2008, superannuation held in a self-managed super fund can be used to borrow money for property purchase. This is done through a 'limited recourse loan' using a Bare Trust as the Custodian entity. You can't borrow the total value of the property—typically it's up to 80% for residential properties and 60% for commercial properties, with the required deposit held in the SMSF as security. The SMSF then makes the loan repayments, with rental income received by the fund and property expenses paid by the fund. Importantly, if there is a default on the loan, your other assets in the SMSF are generally protected from standard debt recovery and bankruptcy proceedings. The lender only has recourse to the property itself. Upon completion of the loan repayment, ownership of the property transfers legally to the SMSF. 2. Follow These 8 Steps to Set Up Your SMSF Setting up an SMSF properly can be a complex process. It’s best to set up an SMSF with the assistance of a qualified superannuation advisor, like us! We can assist with both the initial setup and the ongoing management of your fund. There are eight core steps to SMSF set up: Select the appropriate structure and name Sign the trust deed that covers how your SMSF is set up and run (it can have up to four members) Establish a trust for the SMSF by investing assets into the fund Register your SMSF with the ATO Set up a separate bank account for your fund Submit your tax file number (and those of any other trustees) Obtain an electronic service address to receive employer contributions into your fund (if applicable) Roll over funds from your existing superannuation account into your SMSF 3. Keep a Liquidity Buffer If you're buying property through superannuation, make sure you plan to keep a liquidity buffer of cash and/or shares in your fund. Lenders will check for this before lending to you—it should be at least 10% of the value you intend to borrow. But beyond satisfying the bank, it's simply good risk management. Property is an illiquid asset. Having accessible funds in the SMSF means you're not caught short if repairs are needed, the property sits vacant, or an unexpected expense arises. Because superannuation is central to most Australians' retirement security, the government has carefully regulated what can and can't be done with it. They don't want people gambling their retirement away on poor investments or incorrectly using their superannuation fund. 4. Use the Rental Income to Repay Your Loan You cannot live in the property you purchase through your SMSF until after retirement. Most people purchase an investment property and use the rental income generated to repay the loan—which makes excellent financial sense. The key is selecting a property that rents easily and delivers a strong rental return. Your purchasing criteria may look a little different to buying a home you'd live in yourself. For example, proximity to public transport, local amenities, and average rental rates in the area matter more than personal preference. 5. Get It Right and Enjoy Significant Tax Efficiencies One of the most compelling reasons to invest in property through superannuation is the tax efficiency on offer. These benefits can significantly improve the long-term return of a property investment compared to holding it in your own name. Key tax benefits include: No capital gains tax or tax no yearly investment earnings if under super caps. Salary sacrifice advantages if you're sacrificing salary payments into super, loan repayments are effectively tax deductible. Capped tax on investment income—the maximum rate of tax on income after expenses is 15%. Any capital gains on investments held for 12 months or more, is taxed at 10%. Standard investors outside super can pay up to 47%. 6. Follow the Same Due Diligence Rules as Any Property Purchase Buying through superannuation doesn't mean relaxing your standards. If anything, the rules governing SMSFs mean you need to be more rigorous, not less. Property is likely one of the most significant financial decisions of your life. Research, not emotion, should drive your choices. The same rules apply whether you're buying in or out of super: Visit and compare multiple properties Know the values of similar properties in the same area Get all property checks performed by the right professionals Shop around for the right loan structure and lender Don't abandon good investor habits just because the structure is different. 7. Always Get Quality Professional Advice Nothing comes without risk—but the right advice significantly mitigates it. The key is understanding what you're getting yourself into: making informed decisions based on accurate data; keeping a diversified superannuation portfolio that doesn't place all your eggs in one basket; and not underestimating how complex buying property in superannuation can be. Sound Simple? It’s all in the details. If the above tips have made it sound straightforward, know that the detail is where the complexity lives. Getting professional advice from the start helps ensure you make the best possible decisions for your future. When selected according to rigorous property-purchasing criteria, property can be an excellent way to grow your superannuation and increase your chances of building a retirement fund that supports the lifestyle you want.
