Work-from-Home Tax Deductions for Sole Traders 2025-26
A practical guide to claiming home office expenses as a sole trader in the 2025-26 tax year. Learn the ATO rules, approved methods, and how to maximise your tax deductions.
Work-from-Home Tax Deductions Explained
If you're a sole trader working from home, you can claim tax deductions for the expenses you incur. The ATO allows deductions for the business portion of your home office costs, including rent, mortgage interest, utilities, and depreciation. The key principle is that you can only claim expenses that are directly related to earning your income and that you wouldn't have incurred otherwise.
The Two ATO Methods for Claiming Home Office Expenses
Method 1: The Simplified Fixed Rate Method
The ATO provides two approved methods to calculate your home office tax deduction. You can choose whichever method works best for your situation, but you must be consistent year to year unless your circumstances change significantly.
- Use the ATO's fixed rate of 67 cents per hour (2025-26)
- Calculate the hours you actually worked from home during the tax year
- Multiply hours by 67 cents to get your total deduction
- No need to keep receipts or detailed records of expenses
- Maximum claim of 52 weeks per year (1,820 hours)
- Ideal for sole traders with fluctuating home office use
Method 2: The Detailed Calculation Method
This method requires you to calculate the actual expenses of your home office and claim a proportionate share based on the floor area used for work.
- Identify all home office expenses (rent/mortgage interest, council rates, water, electricity, internet, phone, insurance, depreciation)
- Determine the percentage of your home used exclusively for work
- Calculate your claim as: (total home expense × work area percentage)
- Keep detailed records and receipts for all expenses
- Generally suits sole traders with dedicated office space
- Often results in higher deductions than the fixed rate method
Expenses You Can Claim Using Either Method
Certain expenses can be claimed in addition to whichever primary method you choose:
- Office furniture and equipment (desk, chair, filing cabinet)
- Computer equipment and software
- Office supplies (stationery, printer ink, paper)
- Telephone and internet costs (business portion)
- Professional subscriptions and memberships
- Repairs and maintenance to home office items
- Accounting and tax preparation fees
Important Exclusions and Limitations
The ATO has clear rules about what you cannot claim as a work-from-home deduction:
- You cannot claim the full cost of your home mortgage or rent (only interest on the mortgage, not principal)
- General home maintenance and repairs to non-office areas
- Expenses for a room used for multiple purposes (bedroom that's sometimes an office)
- Personal expenses like meals or entertainment
- Capital improvements to your home (kitchen renovation, new roof)
- Loan repayments on your mortgage
- Cost of cleaning or gardening (unless part of a regular service)
The ATO requires that your home office is used exclusively or almost exclusively for work. If your spare room is used for multiple purposes, you'll struggle to justify the claim.
Practical Tips for Maximising Your Claim
- Keep a diary for at least four weeks to establish your typical home working pattern
- Collect and file all receipts for office equipment and supplies
- Take photos of your dedicated office space
- Document your internet and phone bills (identify the business portion)
- Review your home loan statement for the interest component
- Track any home repairs or maintenance related to the office
- Consult with a tax professional if your situation is complex
Using the fixed rate method requires fewer records, but the detailed method often generates larger deductions. Run the numbers both ways before deciding which suits your situation.
