What the 70c fixed rate covers
- Electricity and gas for heating, cooling and lighting your work area.
- Home and mobile internet and data, and home and mobile phone use.
- Stationery and computer consumables such as printer ink and paper.
You can't claim those costs again separately. Office furniture, computers and other equipment are claimed on top: items costing $300 or less can be deducted straight away, and more expensive items are depreciated.
Car expenses at 91c per km
For work trips in your own car (not your normal trip to and from work), the cents per kilometre rate is 91c for 2026-27 and 88c for 2025-26, up to 5,000 km a year: a maximum claim of $4,550. You don't need receipts, but must be able to show how you worked out the kilometres.
Frequently asked questions
How does the work from home calculator work?
It multiplies the hours you worked from home by the ATO fixed rate of 70c an hour, which covers electricity and gas, internet, phone and stationery, then works out how much tax that deduction saves at your marginal rate plus the 2% Medicare levy. You can add work kilometres in your own car at 91c a km.
How much can I claim for working from home 2 days a week?
About $515: 16 hours a week for 46 weeks is 736 hours at 70c. On a $90,000 income that deduction saves about $164.80 in tax.
What records do I need for the work from home fixed rate?
A record of the actual hours you worked from home for the whole year, made at the time (a timesheet, roster, diary or spreadsheet), and one bill or receipt for each type of running expense the rate covers. Estimates are not accepted.
What is the work from home rate for 2026-27?
The ATO has not yet published a 2026-27 rate. 70c an hour applied in 2024-25 and 2025-26 (67c in 2022-23 and 2023-24), and we use it until the ATO announces the new rate.
