Northrop Grumman’s Australian operations are under audit for how they structure and price transactions with related subsidiaries, just as the company secures fresh local defence work.
The New York-listed group, valued around $US78 billion ($107.6 billion), has been notified that the Australian Taxation Office will review the movement of hundreds of millions of dollars between its local and overseas entities. Authorities are focusing on related party transactions, a key area in transfer pricing rules that govern how multinationals allocate revenue and costs.
The audit comes as Canberra prepares to lift Defence spending in Tuesday’s federal budget, locking in more money for advanced weapons and support systems.
Northrop Grumman recently secured a new $127 million contract from the Defence Department to supply rocket motors for guided missiles, deepening its role in Australia’s military supply chain. The company already supports the Australian Defence Force with aircraft maintenance and digital communications systems, making it a critical partner in several high-end capability programmes.
An ATO review of its cross-border arrangements could influence how much tax it ultimately pays on those sizeable local revenues.
Pressure on the company arrives amid a more strained phase in Canberra-Washington relations, where economic and security interests increasingly overlap. Australia’s cautious stance on potential conflict involving Iran together with the Albanese government’s plan to force platforms such as Meta and Google to either compensate traditional media or face a 2.25% revenue levy already complicates the bilateral agenda.
A tax dispute involving a major US defence contractor now looks like another sensitive point in that relationship, landing right as both countries push for tighter strategic integration.
