ATO work from home calculator - 70c per hour 2025-26 (free)
A single offline HTML page for the ATO revised fixed rate.
Type hours worked from home in 2025-26. It multiplies by 70 cents. Optional daily log stays in this browser; export CSV if you want a file.
Double-click wfh.html. Works from file://. No account.
Not tax advice. Not an ATO product. The ATO expects a record of actual hours for the whole year (not a 4-week estimate) plus one record of each running expense the rate covers. Confirm on ato.gov.au.
