Understanding WFH Tax Deductions in Australia
Since the widespread shift to remote and hybrid work arrangements, the Australian Taxation Office has provided two methods for claiming work from home expenses. The fixed-rate method, introduced from 1 July 2022, allows taxpayers to claim 67 cents for every hour worked from home. This rate covers the costs of electricity, gas, phone, internet, stationery, and computer consumables. Under the fixed-rate method, you cannot claim separate deductions for these items, as they are already included in the 67 cents per hour rate. However, you can claim additional deductions for items not covered by the fixed rate, such as the decline in value (depreciation) of office furniture and technology equipment used for work, as well as any repairs to that equipment.
The actual-cost method requires you to calculate the exact costs associated with working from home and claim them individually. This involves working out the work-related proportion of your electricity, gas, phone, internet, and other running expenses, as well as claiming the decline in value of any depreciating assets used for work purposes. The actual-cost method typically requires more detailed record-keeping, including receipts, bills, and a diary or log of your work from home hours. You also need to calculate the percentage of each expense that relates to work use, which can vary for different items. For example, you might use your internet 50% for work and 50% for personal purposes, while your home office occupies 15% of your total floor space for electricity calculations.
The choice between the two methods depends on your individual circumstances. Workers who have high actual expenses, particularly those with dedicated home offices, expensive equipment, or high utility costs, may benefit more from the actual-cost method. Those with modest expenses or who work from home part-time often find the fixed-rate method simpler and sometimes more generous. The key to maximising your deduction is understanding both methods and choosing the one that gives you the larger claim. This calculator helps you estimate the tax saving under each method so you can make an informed decision before lodging your tax return.
WFH Tax Deduction Formulas
Fixed-Rate Deduction: WFH Hours/Week × Weeks/Year × $0.67
Tax Saving: Deduction Amount × Marginal Tax Rate ÷ 100
Effective Per-Week Saving: Tax Saving ÷ Weeks/Year
Where:
- Fixed Rate = 67 cents per hour (covers electricity, gas, phone, internet, stationery, consumables)
- Actual Cost = Total of individual WFH expense claims based on actual receipts
- Marginal Tax Rate = Your highest tax bracket rate (19%, 32.5%, 37%, or 45%)
Record-Keeping Requirements
Regardless of which method you choose, the ATO requires you to keep records that support your claim. For the fixed-rate method, you need a record of the total hours you worked from home during the income year. This can be a timesheet, roster, diary, or similar document that shows the hours you worked from home. You do not need to keep receipts for the expenses covered by the 67 cents per hour rate, but you do need receipts for any additional claims such as equipment depreciation. For the actual-cost method, you need receipts and bills for all expenses you claim, plus a record of your work from home hours and the method you used to calculate the work-related percentage of each expense. The ATO may ask to see these records if your return is selected for review, so keeping thorough documentation is essential.
Choosing the Right Method for Your Situation
Consider using the fixed-rate method if you work from home regularly but do not have a dedicated home office, if your running expenses are relatively low, or if you prefer a simpler approach with less record-keeping. Consider the actual-cost method if you have a dedicated home office space, if you have invested in expensive equipment or furniture, if your utility bills are high, or if your internet and phone plans have significant work-related usage. In many cases, it is worth calculating your deduction under both methods to see which gives you the larger claim. This calculator allows you to compare both approaches quickly.
Example Calculation
Worker: 24 hours/week WFH, 48 weeks/year, 32.5% tax rate
- Total WFH Hours = 24 × 48 = 1,152 hours
- Fixed-Rate Deduction = 1,152 × $0.67 = $771.84
- Tax Saving = $771.84 × 32.5% = $250.85
- Effective Per-Week Saving = $250.85 ÷ 48 = $5.23
Frequently Asked Questions
What is the ATO fixed rate for working from home?
The ATO fixed rate for working from home is 67 cents per hour, effective from 1 July 2022. This rate covers the additional running expenses you incur when working from home, including electricity and gas for heating, cooling, and lighting, phone and internet usage, stationery and computer consumables. You cannot claim separate deductions for these items if you use the fixed-rate method. However, you can still claim the decline in value of depreciating assets like office furniture and computers on top of the 67 cents per hour.
Do I need to keep a diary of my WFH hours?
Yes, the ATO requires you to keep a record of the hours you work from home during the income year. This can be a timesheet, roster, diary, or any other document that shows your actual hours worked from home. For the fixed-rate method, this is the primary record you need. For the actual-cost method, you also need receipts and bills for all expenses claimed, plus documentation showing how you calculated the work-related percentage of each expense.
Can I claim WFH deductions if I only work from home part-time?
Yes, you can claim WFH deductions even if you only work from home part of the time. Under the fixed-rate method, you simply claim 67 cents for each actual hour worked from home. If you work from home 2 days per week and in the office 3 days, you only claim for the hours worked from home. Under the actual-cost method, you calculate the work-related proportion of your expenses based on your actual usage patterns.
Which WFH method gives a bigger tax deduction?
The method that gives the bigger deduction depends on your individual circumstances. The fixed-rate method tends to be better for people who work from home frequently (many hours per week) but have relatively low running expenses. The actual-cost method can be better if you have high expenses such as expensive internet plans, high electricity costs, or significant equipment depreciation. This calculator allows you to estimate both and compare them to choose the optimal method for your situation.
What marginal tax rate should I use for the WFH calculation?
Your marginal tax rate is the highest rate of tax you pay on your income. For the 2025-26 Australian tax year, the rates are: 0% for income up to $18,200, 19% for $18,201 to $45,000, 32.5% for $45,001 to $120,000, 37% for $120,001 to $180,000, and 45% for income above $180,000. Most full-time workers will use either 32.5% or 37%. Your tax deduction reduces your taxable income, so the tax saving equals the deduction multiplied by your marginal rate.
