Even small additional contributions to your account each month can make a big difference to the size of your super account. There are two ways you can make extra contributions to your super: before tax and after tax.

Before tax (concessional contributions)
Salary sacrifice
You can make extra contributions by ‘sacrificing’ some of your salary. The extra contributions go directly from your salary into your super, the same way your normal super guarantee contributions are paid by your employer.
Your take home pay will be less, however there are potential tax benefits worth considering. Your super is taxed at 15%. If your income tax rate is higher than 15%, then you will save money on tax.
After-tax (non-concessional contributions)
Personal contributions
You can make extra contributions in lump sums from your normal take home pay. This is not taxed as you’ve already paid the tax on the income.
Contribution limits
There are limits to the amount you can add to your super account after-tax. The 2018 - 2019 financial year, the non-concessional cap is $100,000 for all individuals 65 years of age or under. Limits also apply depending on much you already have in your super account.
