What's the difference between personal contributions and salary sacrifice?
That’s why we’re here to help! In this article, we break down the differences between salary sacrifice (before-tax) and personal (after-tax) contributions to help you make the right choice for your future.
Salary sacrifice
Salary sacrifice is where you ask your employer to pay part of your before-tax salary into your super. These are known as concessional contributions.
Here’s how it works:
- You tell your employer how much you want to contribute each pay.
- Your employer pays this on top of the legislated 12% super guarantee (SG) amount.
- These contributions are made before your income tax is deducted, resulting in immediate tax benefits.
Top tip: Stay under the before-tax (concessional) contribution cap of $30,0001 to avoid paying extra tax.
Let's see salary sacrifice in action
Meet Sally
- Age: 30
- Income: $80,000 per year before tax
- Current super balance: Around $80,000
- She salary sacrifices $100 every fortnight into super.
If Sally retires at 67, she could have an extra $141,3002 in her super account.
She’ll also have an estimated tax reduction of $8322 per year.
What are the pros of salary sacrifice?
- It reduces your taxable income, and potentially how much tax you pay.
- Making regular extra contributions to your super over time can make a big difference to your super balance, thanks to the power of compound returns.
- Automatic and regular contributions let your super grow without having to think about it.
Things to keep in mind
- Salary sacrifice contributions are subject to the annual before-tax (concessional) contributions cap of $30,000 per year. The concessional contribution cap also includes your employer SG contributions and personal deductible contributions.
- Salary sacrifice reduces your take-home pay, so consider your current budget before opting-in.
Personal contributions
If salary sacrifice isn’t the right move for you, personal contributions, also known as after-tax contributions, might be a good option.
What are the pros of after-tax contributions?
- You may be able to claim a tax deduction. This will change the contribution to a concessional contribution to reduce your taxable income.
- Earning less than $62,488 before-tax per year? You could be eligible for a government co-contribution.
- Your money will be invested in the tax-effective super environment, to help you build your retirement savings.
Things to keep in mind
- These contributions count towards your after-tax (non-concessional) contributions cap of $110,000 per year.2
