Pre-1 July 1983 amount and tax
If you are a Gold State Super or West State Super member and have an eligible service period that commenced before 1 July 1983, this page is designed to provide important information about your eligible service period and how your tax components are calculated. If you would like to confirm whether this applies to you, please contact your Member Services Centre on 13 43 72.

This page is not intended to be a substitute for the Gold State Super essentials brochure or the West State Super Product Information Booklet (PIB). These documents include all of the information you should consider before making a decision. You should read the relevant brochure or PIB and consider seeking professional legal, taxation or personal financial advice before you act. All examples and scenarios used on this page are for illustrative purposes only.
Impact of pre-1 July 1983 service on untaxed super funds
The eligible service period before 1 July 1983 forms part of the tax-free component of your super benefit. This portion is commonly referred to as the pre-1 July 1983 amount. Determining the pre-1 July 1983 amount to be included in the tax-free component of your super benefit will depend on the tax status of your super fund.
For taxed super funds such as GESB Super, the pre-1 July 1983 amount was calculated as at 30 June 2007 and was included as part of the tax-free component on that date. This is referred to as crystallisation, as the amount became fixed and formed part of the tax-free component.
For untaxed super funds, like West State Super and Gold State Super, the crystallisation of the pre-1 July 1983 amount for the untaxed element in the fund is only calculated when a lump-sum benefit is withdrawn or rolled over into a taxed super fund.
How pre-1 July 1983 service is calculated
Calculating your pre-1 July 1983 amount will have an impact on the tax components of your super benefit and therefore how much tax is payable when you withdraw your benefit from the fund. The tax-free component of your benefit is increased, and the untaxed element is reduced, by your pre-1 July 1983 amount.
Meet John
John is a Gold State Super member who retired on 1 July 2021, aged 60. John started working for the WA public sector on 1 July 1981 and had continuous service until he retired. John’s member contributions were made after-tax and totalled $60,000. John withdraws his Gold State Super benefit of $600,000 on 1 July 2024.
John's total service period of 43 years can be divided to show the pre-1 July 1983 service period of 2 years1 and the post-30 June 1983 period of 41 years1.
Calculating John’s tax components
The pre-1 July 1983 amount is calculated by multiplying his benefit by the pre-1 July 1983 service period divided by the total service period. i.e. $600,000 x 2/43 = $27,907.
The tax-free component of his benefit is the sum of his after-tax member contributions and his pre-1 July 1983 amount i.e. $60,000 + $27,907 = $87,907.
The taxable - untaxed element of his benefit is $512,093.
The amount of tax payable on the taxable component will depend on how John accesses his benefit.
Here are two scenarios involving John and the impact of having a pre-1 July 1983 service period on his tax payable.
Scenario 1 Taking his full benefit as a cash payment
If John took his Gold State Super benefit as a cash payment, the taxable-untaxed element of $512,093 is subject to tax of 17%2,3.
This will result in tax payable of $87,056. If John was under the age of 60 when he took the cash benefit, then the rate of tax could be higher.
More information on tax rates can be found in the Tax and super brochure.
Scenario 2 Rolling over his full benefit to a taxed super fund
If John rolled over his Gold State Super benefit to a taxed super fund, such as our RI Allocated Pension, the taxable component of $512,093 is subject to tax of 15%3 by the taxed fund, resulting in tax payable of $76,814.
The table below illustrates the tax impact of having pre-1 July 1983 service when rolling over to a taxed super fund, such as our RI Allocated Pension.
| Component | Amount | Tax component |
|---|---|---|
Tax-free | $87,907 | Tax free and no tax applies |
Taxable – untaxed element (i.e. the remainder of the benefit) | $512,093 | Taxable – untaxed element and is subject to tax |
Gross benefit | $600,000 | |
Tax payable on rollover of 15% | $76,814 | |
Net benefit (after tax) | $523,186 |
The net benefit (after tax) comprises a tax-free component of $87,907 and a taxable component – taxed element of $435,279 (i.e. $512,093 less tax of $76,814).
John gains a tax saving of $10,242 (scenario 1 tax of $87,056 less scenario 2 tax of $76,814). This is because the Medicare Levy is not payable on rollovers as it is with cash payments (as in scenario 1 above). As John is over age 604, any regular income payments or lump-sum payments from his allocated pension will also be tax free.

Maximising your tax-free component
Members who have pre-1 July 1983 eligible service and have an untaxed super fund, such as Gold State Super or West State Super, may be able to maximise their tax-free component by making personal after-tax contributions to their untaxed super fund before accessing their benefit.
This is a complex area and we recommend you seek professional legal, taxation or personal financial advice.
Gold State Super members who are currently employed in the WA public sector may be eligible to open a West State Super account, provided they have pre-1 July 1983 service. Please contact your Member Services Centre on 13 43 72 to find out more.
Other considerations
Untaxed plan cap
Moving from one untaxed super fund, such as Gold State Super, to another untaxed super fund, such as West State Super, will not trigger the pre-1 July 1983 crystallisation in Gold State Super.
It is important to understand that rolling over your entire benefit to West State Super will mean you only have one untaxed plan cap3 when you access your Final Benefit. Effectively, the untaxed benefit in Gold State Super is assessed twice. First, in Gold State Super when you roll over to West State Super (i.e. against your untaxed plan cap3 in Gold State Super), and then again when you access your benefit in West State Super (i.e. against your untaxed plan cap3 in West State Super).
Non-concessional contributions cap
If you are considering making additional after-tax contributions into your West State Super account, then the non-concessional contributions cap of $120,000 per annum for the 2025/26 financial year will apply5.
If you are aged under 75 at any time in the financial year, you may be able to bring forward one or two years of non-concessional contributions i.e. $120,000 plus $240,000, giving you a cap of $360,000 over three years. Where a bring forward arrangement has been triggered, the future years' entitlements are not indexed and they must be made before you turn 75.
If your total super balance is equal or greater than $2 million on 30 June of the previous financial year then your non-concessional contributions cap is nil for the financial year. This is tested each 30 June, including during the bring-forward period.
The amount available under the bring-forward rule depends on your total super balance as at 30 June in the previous financial year.
1 Please note, the formula is based on number of days, however we have used years to simplify.
2 Includes 2% Medicare Levy.
3 There is an untaxed plan cap per super fund which is $1.865 million for the 2025/26 financial year (indexed annually in line with Average Weekly Ordinary Time Earnings, in increments of $5,000 rounded down). The untaxed plan cap are taxed at 15% on rollover to a taxed fund. Amounts above your untaxed plan cap are taxed at 47% prior to rollover.
4 If you are aged 60 or over, your regular income stream payments or lump-sum payments will be tax free and you will not be required to include these payments in your income tax return.
5 Non-concessional contributions to all of your super funds will count towards your non-concessional contributions cap (including non-concessional contributions made to Gold State Super and West State Super).
