The main trends shaping Spain’s transfer pricing land - scape for 2026 are clear: • intensified scrutiny of financial transactions (with cash pool symmetry, short-tenor benchmarks and debt capacity narratives front and centre); • tighter discipline in respect of intra-group services (narrow low value-adding services (LVAS) eligibility, stronger benefit tests and better cost traceability amid cross-border mobility); • development, enhancement, maintenance, protec - tion and exploitation (DEMPE)-driven allocation of returns for intangibles in increasingly digital busi - nesses (with synergies, location savings and work - force in place treated as comparability factors); and • a pragmatic administrative practice that relies on interquartile narrowing and, when needed, median- based adjustments. These trends are unfolding alongside greater expec - tations for contemporaneous documentation, year- by-year testing and governance that integrates tax, treasury, HR and legal aspects, thereby raising the premium on data quality, defensible narratives and audit-ready files. Financial Transactions: Cash Pooling, Leverage and Debt Capacity Intercompany financing remains one of the most scru - tinised areas in Spanish transfer pricing audits. Cash pooling structures, short-dated liquidity bridges and group lending arrangements are common treasury tools but also frequent sources of controversy. The central theme for 2026 is accurate delineation: align - ing the pricing outcome with the actual functions

performed, assets used and risks controlled. Spanish case law and the OECD Transfer Pricing Guidelines converge on a fact-driven approach, with particular attention to the mutual liquidity function of pools, the very short-term nature of intra-pool balances and the typically administrative role of the pool leader. Where facts support that profile, symmetry between credi - tor and debtor rates and the absence of a bank-like spread for the leader are consistent with arm’s length behaviour. Design principles for cash pooling A robust cash pool policy should be explicit on: • the pool mechanics (zero-balancing versus notion - al, sweep frequency, overdraft rules); • decision rights and constraints on the leader; • allocation of credit and liquidity risks (including who monitors counterparty risk and sets limits); and • the reference benchmarks for pricing. Policies should avoid ambiguity that could imply the leader sets rates at discretion or intermediates risk like a bank, unless that is the intended operating model supported by capabilities and third-party references. Where the leader simply co-ordinates daily sweeps, keeps records and neither allocates funds at dis - cretion nor bears credit or liquidity risk, the leader’s remuneration should mirror a low-risk co-ordinator fee, not a financial intermediary margin. This aligns with Spanish jurisprudence describing the leader as a mere administrator in a zero-balancing system and with the OECD’s focus on control over risks and finan -
