Rule version
Version CC-2026-27-v1, approved on 2026-10-18, last validated on 2026-10-18. Rules are effective from 2026-07-01 to 2027-06-30. Published rule versions cannot be edited; corrections are released as a new version.
Calculation assumptions
- Full-year resident employee in the Cocos (Keeling) Islands under Australian income-tax law.
- Annual salary AUD50,000-100,000 excluding employer super, with no study debt, salary sacrifice, reportable fringe benefits, insurance premiums or other deductions.
- The AUD1,000 standard work-related deduction applies under section 25-130 because this wages-only profile claims no competing work-expense deductions. It reduces taxable income, not cash salary.
- Employer super is 12% of qualifying earnings under Payday Super from 1 July 2026. For this ordinary wages-only profile, qualifying earnings equal entered salary; payment deadlines do not change annual cash take-home.
- The Working Australians Tax Offset starts in 2027-28 and is not applied here. Annual liability estimate, not PAYG withholding or a completed-year payslip.
