In This Tax Optimization Guide:
1. ATO Work From Home (WFH) Deduction: 67¢/hr vs Actual Cost Method
Under ATO Practical Compliance Guideline PCG 2023/1, Australian workers carrying out employment duties from home have two statutory deduction paths:
Covers your energy expenses (electricity and gas), phone and internet usage, and computer consumables (stationery/printer ink). You do not need dedicated home office space, but you must maintain an active record or timesheet of all hours worked throughout the entire year.
Requires itemizing actual running expenses by calculating the exact cost per kilowatt-hour of electricity, apportioning home internet bills, and calculating mobile phone call percentages.
2. Sole Trader & ABN Tax Deductions Checklist

4. Legislated Stage 3 Tax Cuts & Take-Home Pay Impact
The Australian Parliament enacted the revised Stage 3 tax framework under the Treasury Laws Amendment (Cost of Living Tax Cuts) Act 2024. The revised schedule provides broad-based relief across every Australian taxpayer:
| Taxable Income Tier | Marginal Tax Rate | Base Tax Payable |
|---|---|---|
| $0 – $18,200 | 0.0% (Tax-Free Threshold) | $0 |
| $18,201 – $45,000 | 16.0% (Reduced from 19%) | $0 + 16¢ for each $1 over $18,200 |
| $45,001 – $135,000 | 30.0% (Reduced from 32.5%) | $4,288 + 30¢ for each $1 over $45,000 |
| $135,001 – $190,000 | 37.0% (Threshold lifted to $190k) | $31,288 + 37¢ for each $1 over $135,000 |

5. HECS/HELP Debt Repayment Thresholds & WPI Indexation Relief
The Commonwealth Government reformed Higher Education Loan Program (HELP) indexation to eliminate debt ballooning. Key statutory changes include:
- Lower of CPI or WPI Indexation Cap: HECS-HELP debt indexation is permanently capped at whichever is lower between the Consumer Price Index (CPI) and the Wage Price Index (WPI).
- Retrospective Relief Credits: The statutory reform backdated credits to counteract the 7.1% indexation spike from 2023, wiping out billions in accumulated graduate balances.
- Compulsory Repayment Tapers: Repayments begin when statutory repayment income exceeds the legislated minimum threshold, scaling progressively up to 10% for high earners.
