Can ABN tradies claim phone and internet?
Yes, claim the business-use portion of phone and internet costs, supported by bills and a reasonable work-use calculation.
Last updated: 7 July 2026. General information for Australian tradies. Not personal tax advice.
Business phone use
Client calls, supplier calls, job photos, maps between sites, quoting apps, emails and invoice follow-ups can all support business use.
Internet use
Cloud accounting, job management, email, online supplier orders and BAS preparation can support a business-use internet percentage.
Avoid double counting
If phone/internet are already included in a home office fixed-rate claim, do not claim the same cost again as an actual ABN expense.
Where to enter it in TradieCalc
