How fixed rate works

We multiply your estimated WFH hours by the ATO 67c/hour rate for the 2025-26 planning comparison.

How actual cost is estimated

We use your electricity bill, WFH hours, and workspace size as a conservative signal, not a lodging-ready claim.

What TaxBoy does next

Forward WFH receipts into TaxBoy during the year, then export evidence for your accountant at EOFY.

Important note

The fixed-rate method uses the ATO 67c/hour rate. The actual-cost figure is a simple running-cost estimate from your electricity bill, WFH hours, and home office area. It is an estimate only.
