Can ABN tradies claim home office expenses?
Yes, if the home office cost relates to running your ABN business and you keep records showing the business-use portion.

What ABN home office covers
ABN tradies often work from home on quotes, invoices, bookkeeping, BAS, rosters, client emails and ordering materials. Running costs, office furniture and equipment can be relevant when the work connection is clear.
Fixed rate vs actual costs
If using a fixed-rate style calculation, avoid double counting phone, internet, energy and stationery. If using actual costs, keep bills and a business-use calculation.
What records help
Keep a diary of admin hours, floor-area notes for a dedicated office, bills, invoices, and a short explanation of how the business percentage was calculated.
