Direct answer: resources tax outcomes follow the project lifecycle, asset location, joint-venture model, mobile workforce, technical functions, financing and decision-making. An overseas project can create a taxable presence before a local company is incorporated, while a founder or executive already offshore can alter company control and service attribution.
Key cross-border tax risks
Project, exploration, joint-venture and branch structures
Permanent establishments and profit attribution across project phases
Transfer pricing for management, technical, procurement and marketing services
Cross-border debt, guarantees, interest and withholding taxes
Mobile workforce, payroll, contractor and immigration exposure
Farm-ins, acquisitions, disposals, rehabilitation and exit readiness
What changes the tax result
Which entity holds the licence, asset and project risk?
The licence holder, operating entity, joint-venture participants and service companies should reflect the actual allocation of capital, geological risk, construction risk and operating responsibility.
Where are technical and strategic functions performed?
Exploration planning, engineering, procurement, project control, treasury and offtake decisions can support service charges or create taxable presence depending on where people operate.
How long do people and projects remain in-country?
Project duration, recurring site visits, offices, equipment and dependent agents affect permanent establishments, payroll and local registrations.
Where is the group managed and financed?
Board authority, treasury, guarantees and senior management should be mapped across Australia, the project country and any regional hub.
Worked scenario
An Australian resources-services group wins a multi-year African project. Australian engineers rotate through site, a local project company is formed, equipment is imported and the Australian headquarters provides procurement, treasury and technical oversight.
The tender economics should be revisited for project permanent establishments, service attribution, payroll, withholding, equipment charges and financing. Intercompany contracts and time records must support who performs each function and bears each risk.
Evidence to assemble
Licences, joint-venture and project agreements
Tender assumptions, project schedules and site-presence records
Technical, procurement, management and secondment agreements
Employee, contractor, payroll and travel data
Debt, guarantees, treasury and equipment records
Board, investment and disposal documentation
How Extax helps
Extax supports tender-stage modelling, project and joint-venture structures, permanent establishments, service attribution, financing, mobile workforces and transactions. The review can begin before mobilisation or after a project has already created exposure.
