How it works in practice
Understanding the Actual Cost Method
For the 2026 financial year in Australia, the actual cost method for work-from-home deductions allows you to claim the exact work-related portion of specific expenses incurred while working from home. This method requires meticulous record-keeping to substantiate every claim.
Eligible Expenses and Record-Keeping
Under this method, you can claim the work-related percentage of expenses such as electricity (for heating, cooling, and lighting your workspace), internet service, phone usage, stationery, and the decline in value (depreciation) of office furniture and equipment. To do this, you must keep all receipts, bills, and a diary or logbook detailing your work-related usage (e.g., hours worked from home, internet data usage for work, or phone call logs).
Calculating Your Claim
To calculate the work-related portion, you typically need to determine the area of your dedicated home office as a percentage of your home's total area. For shared utilities like electricity, you'd then apply this percentage, or a specific usage calculation, to the relevant bills. For depreciating assets, you'd calculate the decline in value based on their cost and effective life, then claim the work-related percentage.
Important exceptions
You cannot claim general household occupancy expenses like rent, mortgage interest, property rates, or house insurance, unless your home is genuinely treated as a place of business, which has significant capital gains tax implications.
Expenses that are reimbursed by your employer are not claimable. You also cannot claim the personal-use portion of any expense. Tax rules are subject to change each financial year, so always check the latest ATO guidance for the 2026 financial year closer to the time.

Maintain detailed records, including receipts, invoices, and bank statements for all work-from-home expenses.
