Fixed Rate vs Actual Cost: Which WFH Tax Deduction Method Is Best
When you work from home, you can claim tax deductions for your home office expenses through the Australian Taxation Office. There are two main ways to do this: the fixed rate method and the actual cost method. Each option has its own set of rules, and the best choice depends on your personal situation. We’re here to help you understand these methods so you can make the most of your working from home tax deductions.
Understanding the Fixed Rate Method
Introduced to simplify record keeping, the revised fixed rate method allows taxpayers to claim 70 cents per hour worked from home during the 2024–25 income year, up from 67 cents per hour in previous years. This rate covers additional running expenses such as energy expenses (electricity, gas), home internet, mobile phone expenses, stationery expenses, and computer consumables. These expenses covered are considered common working from home expenses and are included in the fixed rate calculation for the entire income year.
How It Works
To use the revised fixed rate method, taxpayers must maintain detailed records of actual hours worked from home across the income year. Acceptable documentation includes timesheets, spreadsheets, diaries, or employer rosters. The ATO emphasizes that estimates or retrospective calculations are not sufficient-records must be contemporaneous. For example, an individual working 38 actual hours weekly could claim $1,383.20 annually under the new fixed rate method.
Pros and Cons
The fixed rate method’s primary advantage is its simplicity. By applying a flat rate per hour, taxpayers avoid complex calculations and detailed expense tracking for running expenses. However, this approach has limitations:
It excludes high-value home office equipment or office furniture and technology depreciations, which must be claimed as a separate deduction.
Taxpayers cannot claim additional deductions for expenses already covered by the fixed rate, such as internet bills or energy expenses, in their tax return.
This method suits those with predictable home expenses and limited time for administrative tasks. However, it may disadvantage individuals with higher-than-average home office expenses, such as business owners or freelancers requiring specialised office equipment or a dedicated home office space.

Exploring the Actual Cost Method
The actual cost method offers flexibility by allowing deductions for actual expenses incurred while working from home. This includes running expenses like energy bills, home internet, mobile phone expenses, stationery, and depreciation of home office equipment, office supplies, and home office furniture used for employment duties.
Eligibility and Requirements
To use the actual cost method, taxpayers must:
Incur additional running expenses directly tied to work activities (for example, lighting costs in a dedicated home office).
Maintain detailed records, including receipts, bills, and logs apportioning work related use versus private portion for each expense. For example, a four-week diary tracking mobile phone usage could establish a work-related portion for annual claims.
Pros and Cons
The actual cost method often yields higher tax deductions for those with significant working from home expenses. For example, a business owner with a dedicated home office or dedicated home office space could claim portions of occupancy expenses (like mortgage interest, rent, land taxes, and house insurance premiums) if their home is their principal place of business. However, the administrative burden is substantial:
Taxpayers must catalog every expense and justify the work related portion.
Incorrect apportionment or insufficient documentation risks ATO audits and rejected claims, making record keeping essential.
This method benefits self-employed individuals, freelancers, or employees with a dedicated home office and substantial overheads. Conversely, those with minimal tasks or hybrid work arrangements may find the effort outweighs potential benefits.
Key Factors to Consider When Choosing a Method
1. Nature of Work and Expenses
Employees with minimal working from home hours or standard running expenses often prefer the fixed rate method for its ease. Conversely, those with high-speed home internet, specialised office equipment, or a dedicated home office may save more with the actual cost method, especially if they can claim occupancy expenses.
2. Record-Keeping Capacity
The fixed rate method requires only hourly logs, while the actual cost method demands meticulous record keeping for all home office expenses and a clear separation of work related and private portion for each item. Taxpayers lacking time or organizational systems may struggle with the latter.
3. Impact of Recent ATO Changes
The 2024 rate increase to 70 cents per hour enhances the revised fixed rate method’s appeal, but it also consolidates previously separate deductions (e.g., home internet, stationery expenses). Taxpayers must evaluate whether the streamlined rate compensates for lost individual claims in their tax return124.
4. Long-Term Financial Planning
Investments in home office furniture, office equipment, or other depreciating assets may justify the actual cost method due to the ability to claim decline in value over multiple years. This is particularly relevant for those with a dedicated home office or principal place of business.

Practical Recommendations for Taxpayers
Use the ATO’s Home Office Expenses Calculator
The Australian Taxation Office provides a home office expenses calculator to help estimate deductions under both the fixed rate and actual cost method, giving a data-driven starting point for your tax return.
Consult a Tax Agent or Tax Professional
Complex scenarios-such as mixed-use spaces, claiming occupancy expenses, or being a business owner-often require tailored advice to optimise home tax deductions and ensure compliance with ATO rules.
Leverage Time Tracking Apps and Digital Tools
Apps and cloud-based spreadsheets can automate hourly tracking and expense categorization, reducing administrative strain for both methods.
Stay Informed on Updates
ATO policies for working from home tax deductions evolve annually. Subscribing to updates from trusted sources ensures compliance with rate changes, eligibility criteria, and record keeping requirements.
Conclusion: Making the Right Choice for Your Situation
Choosing between the fixed rate and actual cost method for your WFH tax deduction hinges on balancing simplicity against potential tax savings. For most employees, the revised fixed rate method offers a hassle-free solution, particularly with the 2024 increase to 70 cents per hour. However, those with higher home office expenses, a dedicated home office, or significant occupancy expenses should carefully compare both methods-the actual cost method could unlock substantial tax deductions worth the extra effort.
Whichever method you select, rigorous record keeping remains non-negotiable. The Australian Taxation Office’s focus on working from home expenses means incomplete documentation risks penalties or rejected claims. By understanding both options and planning ahead, Australians can confidently claim working from home tax deductions and maximise their entitlements at tax time.
