Transfer Pricing in Gibraltar

The legal framework

Gibraltar has no freestanding transfer pricing code and no OECD Transfer Pricing Country Profile; the arm's length principle enters chiefly through the general anti-avoidance rule in the Income Tax Act 2010. Section 40, substituted by the Income Tax (Amendment) Act 2025 (No. 10 of 2025, in force 11 July 2025), must be construed to secure consistency with internationally accepted principles for determining profit within a multinational group and with the documents the OECD publishes as part of its Transfer Pricing Guidelines (s.40(3)(b)–(c)); the reference is open-ended, so the current Guidelines apply without further enactment. Section 74 separately defines an "artificial and fictitious" arrangement to include one inconsistent with the arm's length principle in the Guidelines "as amended from time to time", but the reformed s.40 no longer uses that term, which survives only in the Schedule 3 start-up relief anti-abuse rule.

The adjustment mechanics sit in Schedule 4. Paragraph 4(1) lets the Commissioner assess a person dealing with a connected person on the profits that would ordinarily have arisen where the course of business yields no profit, reduced profit or an inflated loss. Paragraph 4(2) deems connected-party interest above an arm's length amount to be a non-deductible dividend, and paragraph 4(3) caps connected-party expense deductions at the least of the expense, 5% of gross turnover and 75% of pre-expense net profit. Paragraph 2 adds a 5:1 debt-to-equity thin capitalisation rule for interest on loans from, or secured on the assets of, connected non-corporate persons. Paragraph 7 disapplies the rules where the taxpayer satisfies the Commissioner that the arrangement was bona fide commercial, not tax-motivated and proportionate, and that decision is appealable.

"Connected person" turns on control (Schedule 4 para 9), not a shareholding percentage; the 25% "associated enterprise" test in para 8A serves only the ATAD-derived interest limitation, hybrid and CFC rules. Companies pay 15% on income accruing in or derived from Gibraltar from 1 July 2024, so the pricing question is often entangled with the territorial-source test in s.11(1).

Methods, comparables and benchmarking

The statute is silent on methods: it names none, states no hierarchy and prescribes no tested party, range or point within it. Everything routes through the OECD Guidelines via s.40(3)(c), so Chapters II and III apply. The Income Tax Office has issued no benchmarking guidance and stated no preference between local and regional comparables. With a negligible domestic comparable pool, pan-European sets built on OECD-consistent screens are the working default, supported by a documented interquartile range and a reasoned point within it.

Two statutory overrides sit above any benchmark. Connected-party interest must be arm's length as to both rate and terms (Schedule 4 para 2), and the para 4(3) cap operates mechanically: a benchmarked management fee is still limited by the 5% turnover and 75% profit ceilings unless para 7 is invoked. On Pillar One Amount B, Gibraltar has published nothing; the open-ended s.40(3)(c) reference brings the Amount B annex within the reference text, but no election to apply or accept it exists and a counterparty's adoption does not bind the Commissioner. The Act mandates an arm's length computation in only a few places: connected-party interest (Schedule 4 para 2(1)), the excess-interest deemed dividend (para 4(2)), the CFC rule (para 20(a)) and the para 8A long-term public infrastructure carve-out.

Documentation: what the Income Tax Office expects

Neither the Act (consolidated to 23 March 2026) nor Income Tax Office guidance requires a master file, a local file or any monetary documentation threshold. What exists is the general duty in s.63: records sufficient to support a full and complete return, preserved for six years from the end of the period (longer while an enquiry is open), including contracts, invoices and other underlying documentation significant to the trade, kept in English (s.63(7)). A s.32 production notice in an enquiry allows at least 30 days, and copies suffice.

Section 40(5) reverses the burden of proof, so the taxpayer must show an arrangement was not designed for tax avoidance, and para 7 relief turns on satisfying the Commissioner of commercial purpose and proportionality. The functional analysis, intercompany agreements and benchmarking study are therefore what a Gibraltar company must be able to produce on 30 days' notice; an OECD-format local file is the pragmatic answer even though nothing compels it.

The annual return is Form CT1, filed with signed accounts and a computation nine months after the end of the month in which the period closes; audited accounts are required where assessable income exceeds £1,750,000 for periods ending on or after 1 July 2024. No related-party schedule is published. Country-by-country reporting sits in Part 1B (ss.10L–10ZD): groups at or above EUR 750 million revenue (s.10M) file within 12 months of year end (s.10T), local filing applies where the parent's jurisdiction has no exchange agreement (s.10O), and every Gibraltar constituent entity notifies its filer status by its own return deadline for the preceding year (s.10R). Gibraltar signed the CbC MCAA on 7 May 2020 after exchanging under DAC4 until the end of 2020; filing is via the AEOI portal.

Audits, penalties and the enforcement climate

The Commissioner must open an enquiry within one year of receiving the return (s.31(4)) but may assess or amend within six years of the period end (ss.31A, 34(3)) and within twenty years where fraud, wilful default or neglect is present (s.34(4)).

There is no transfer pricing penalty as such. An adjustment under s.40 or Schedule 4 is collected by assessment; late payment attracts a 10% surcharge the day after the due date and a further 20% after 90 days (s.64), and where the return was negligent, reckless or fraudulent the s.66 penalty runs to 150% of the tax difference, calibrated by the Schedule 8 tables on amount, behaviour and cooperation. Section 66A lets the Commissioner waive or reduce where there was no intent to avoid or defer tax. Ignoring a s.32 notice costs £200, then £1,000 after a month (s.65A), with criminal exposure under s.65B for continued intentional or reckless failure. Late CT1 penalties are size-tiered from 1 January 2025: £100/£450/£750 for micro and small companies rising to £1,500/£3,500/£5,000 for large ones (s.65).

Transfer pricing has become a priority for the Income Tax Office, which has added resources and is upskilling, and the OECD's October 2025 dispute resolution profile notes redesigned cross-border training for assessing officers. Add the GAAR's adviser-referral power (s.40(5)), and a jurisdiction that has never litigated a transfer pricing case now has both the tools and the intent.

Dispute resolution and advance certainty

The OECD dispute resolution profile (24 October 2025) records no mechanism for advance pricing arrangements, unilateral or bilateral, and the Income Tax Office's MAP guidance (para 7.8) confirms MAP will not be used to negotiate one.

Gibraltar's only comprehensive DTA is with the United Kingdom (in force 24 March 2020, effective for Gibraltar income and corporation tax from 1 July 2020). Article 9 carries the associated enterprises rule, including the Article 9(2) corresponding-adjustment obligation in OECD Model form; Article 24 allows a MAP request to either competent authority within three years of first notification, overrides domestic time limits when implementing an agreement, and provides mandatory binding arbitration at the taxpayer's request for issues unresolved after two years. The 2019 Spain–UK International Agreement on Gibraltar (in force 4 March 2021) is not a DTA and offers no Article 9 or taxpayer-initiated MAP, though its competent authorities must eliminate double taxation under domestic law and its Joint Coordination Committee may resolve residency conflicts and interpretive difficulties by mutual agreement where all the authorities so decide. For every other counterparty, relief from economic double taxation depends on the other side's unilateral goodwill.

Where MAP applies it is taxpayer-friendly on paper: no fee, requests in English to MAPRequests@gov.gi, transfer pricing cases admitted, corresponding adjustments made whether or not the treaty contains Article 9(2) wording (para 7.5), and access preserved where domestic anti-abuse rules are engaged or domestic remedies exhausted. Collection is not automatically suspended, though postponement may be requested, and penalties flowing from a MAP outcome may be reduced (para 7.10). Gibraltar has received a single MAP request, a non-transfer-pricing case resolved in 2022 in roughly nine months; none has concerned transfer pricing.

Domestically, an appeal against an assessment or a Schedule 4 counteraction goes to the Commissioner within 28 days and on to the Income Tax Tribunal (s.35, Schedule 2), with a case stated to the Supreme Court on a point of law within 21 days of the determination. No reported Gibraltar transfer pricing judgment exists; the leading tax litigation has been State aid (C-705/20), not pricing.

Pillar Two and what changes in 2026

The Global Minimum Tax Act 2024 (No. 2024-20, assented 23 December 2024, deemed in operation from 31 December 2023) incorporates the OECD GloBE Model Rules and Commentary directly, applying a Domestic Top-up Tax to fiscal years beginning on or after 31 December 2023 and an Income Inclusion Rule from 31 December 2024 for groups at EUR 750 million or more; the UTPR is excluded. Registration on Form GMTAREG1 was due by 28 February 2026 for groups whose first in-scope year ended between 31 December 2024 and 31 August 2025, and within six months of year end otherwise. The first GloBE Information Return (FY2024) fell due 30 June 2026; FY2025 returns are due 31 March 2027, with Form GMTA1 where Gibraltar top-up tax arises. Penalties are modest (£1,000 for a missing GIR or notification, s.43), and the Commissioner will waive local-filing penalties in the OECD's transitional central-filing scenarios.

The transfer pricing angle is s.40(6): the 2025 Rules let a Gibraltar Parent Entity elect out of the Income Tax Act into the GMT Act alone, and the GAAR expressly lets the Commissioner counteract that election where the motive is a tax advantage. Spain removed Gibraltar from its non-cooperative list by Orden HAC/649/2026 of 21 June 2026, published in the BOE on 27 June and in force the next day; the Spanish Ministry of Finance grounds the removal in the 2019 Spain–UK Agreement rather than the 14 July 2026 EU–UK agreement. The Order reaches periodic taxes only for tax periods beginning on or after 28 June 2026 and preserves the old list for periods already running, so a calendar-year Spanish group still treats Gibraltar as non-cooperative for FY2026 and feels the full effect from FY2027; from then Spanish transfer pricing anti-abuse rules bite only on related-party dealings rather than every Spain–Gibraltar transaction, though Spanish audit years from 2022 remain exposed. The 7 July 2026 Budget announced no rate change and no new transfer pricing measures.

How practitioners should respond

Treat Gibraltar as an OECD jurisdiction without an OECD rulebook. Prepare an OECD-format local file and executed intercompany agreements as if s.40(5) will be invoked, because the burden sits with the taxpayer and para 7 relief is won or lost on contemporaneous evidence of commercial purpose. Model the para 4(3) cap and the 5:1 thin-cap ratio before pricing any service fee or loan; a benchmark alone does not clear them. Diary the one-year enquiry window and the six- and twenty-year assessment horizons. For UK counterparties, build Article 9(2), Article 24 MAP and arbitration into the dispute strategy; for everyone else, price conservatively because there is no treaty backstop. Register Pillar Two groups, align the GIR and CbC calendars on the AEOI portal, and revisit Spanish exposure after the June 2026 de-listing, remembering that calendar-year Spanish counterparties feel it only from FY2027. Finally, watch the Income Tax Office: its new resourcing means the first Gibraltar transfer pricing enquiry is a matter of when, not whether.
