How do our calculation engines work? All financial estimators on WHM Super Claim operate on statutory tax rates established under Commonwealth law, specifically the Superannuation (Departing Australia Superannuation Payments Tax) Act 2007 and its 2016 WHM amendments. Calculations execute client-side in real time using verified Australian Taxation Office (ATO) withholding formulas.
1. Main DASP Net Payout Formula
To determine the net payout arriving in a user's bank account, our engine applies statutory withholding tax rates ($T$) directly to the gross super balance ($B$):
Where the Statutory Tax Rate ($T$) is assigned using the following multi-variable decision tree:
| Visa / Account Scenario | Applied Rate ($T$) | Statutory Authority |
|---|---|---|
| Account containing Working Holiday (417/462) contributions | 65.0% | Superannuation (DASP Tax) Amendment Act 2016 |
| Account with ONLY non-WHM contributions (Student 500 / Skilled 482) | 35.0% | Taxed element of fund-held super (Ordinary Rate) |
| Untaxed Element (Rare public sector schemes) | 45.0% | Untaxed element of fund-held super |
| ATO-Held Unclaimed Super (Transferred ~6 months post-departure) | 65.0% | Unclaimed Superannuation Money Act 1992 (All visas) |
2. Super Guarantee (SG) Balance Estimator Engine
When users do not know their exact super balance, Tool 2 estimates total accrued super based on gross earnings in Australia ($W$) and the statutory Super Guarantee rate ($R_{SG}$) applicable during their period of employment:
Our calculator dynamically applies historical and current Super Guarantee rates enacted under Australian law:
| Employment Period | Statutory SG Rate ($R_{SG}$) |
|---|---|
| Prior to 1 July 2021 | 9.50% |
| 1 July 2021 – 30 June 2023 | 10.00% – 10.50% |
| 1 July 2023 – 30 June 2025 | 11.00% – 11.50% |
| 1 July 2025 onwards | 12.00% (Current Statutory Standard) |
3. The 6-Month ATO Deadline Tracking Logic
The deadline checker calculates the date at which super funds are legally required to transfer unclaimed former temporary resident super balances to the ATO under the Superannuation (Unclaimed Money and Lost Members) Act 1992:
For Student (500) and Skilled (482) visa holders, crossing this 183-day threshold triggers an automated alert indicating that their tax withholding rate has increased from 35% to 65%.
