Yes. Intra-group service arrangements — including management fees, shared services allocations, and royalty payments — are a frequent target of FNS field audits directed at foreign-owned groups. The FNS challenges these arrangements under Article 54.1 by questioning whether the services were actually performed, whether they had a business purpose beyond tax reduction, and whether the counterparty actually performed the services under the contract. The defence requires contemporaneous documentary evidence of the services' performance, including contracts, acts of performance, communications, and evidence of the counterparty's capacity to perform.
