How do I make a contribution to my super through Member Online?
You can make contributions to your super in two different ways; before tax (salary sacrifice) or after tax.
You can make after-tax contributions to your account through your employer, by using BPAY® or by cheque or money order. These are known as personal contributions - and we don’t charge you any fees for contributing to your account in these ways.
In Member Online you can submit a request to your employer to start making contributions to your super from your pay. Please note, some employers can’t accept our form, so you’ll need to get a form directly from your employer. Check with your payroll department for details.
To make contributions, we need to have your tax file number (TFN). You can provide your TFN through Member Online in the ‘Personal details’ section, if you haven’t done this already.
To make a contribution, log in to Member Online and visit the ‘Contribute’ page.
![]()
You’ll find a section called ‘Before-tax contributions’ and a section called ‘After-tax contributions’.

If you’d like to make an after-tax BPAY contribution, you’ll find the biller code and your unique BPAY reference number in this section. You can copy or print these details to make your contribution through your bank or financial institution.
You’ll also find links to contribute through your employer or contribute by money order or cheque.
These links will direct you to a form to complete, depending on which type of contribution method you choose.
You can complete and print the money order or cheque form and post in with your contribution.

If you choose to make a contribution through your employer, you can choose whether you would like to make a before-tax (salary sacrifice) or after-tax contribution. You can choose whether you’d like to contribute a set amount or percentage of each pay, if you’re eligible.

Once you’ve completed the form, you’ll need to read and agree to a declaration and submit your form.
We will then send your request to your employer and confirm this with you by email.
Whether you make a BPAY, cheque or money order or an employer contribution, your contributions will appear in your transactions on your ‘Accounts’ page once they’ve been processed.

How does the concessional (before-tax) contribution cap work if I have more than one super fund?
Your concessional contributions cap is the total amount of before-tax contributions you can make in a financial year before you may have to pay extra tax. If you have a GESB Super account and a West State Super account, or a GESB account and an account with another taxed fund, and you make concessional contributions to both, these contributions will be counted towards the cap. However, once you exceed the cap, only additional contributions made to your GESB Super account and other taxed funds over the cap will be taxed at the higher tax rate. Amounts over the cap that are contributed to untaxed funds, such as West State Super, won’t count and therefore won’t be subject to extra tax.
For example, if you make $20,000 in before-tax contributions to your West State Super account and $20,000 to your GESB Super account (including your employer Superannuation Guarantee contributions and any voluntary amounts), $10,000 will be taxed at the higher rate as it will have exceeded the $30,0001 cap for the financial year. However, if you then add another $20,000 to your West State Super account, this won’t be subject to extra tax as it is not counted as exceeding the cap. If you made a further $5,000 in concessional contributions to your GESB Super account - or another taxed fund - that money will be counted as exceeding the cap and be taxed at a higher rate.
For this reason, it’s important you consider before-tax contributions in all your super funds when tracking your contributions, if you have more than one fund or account. You can track contributions to your GESB accounts in Member Online.
1 For the 2024/25 financial year. The concessional contributions cap is indexed annually in line with Average Weekly Ordinary Time Earnings in increments of $2,500 rounded down.
