The Global Minimum Tax Arrives: What It Means for Jamaica and the Multinationals Operating Here Denzil Alexander Whyte, Managing Partner, Signature Creed & Associates

The Global Anti-Base Erosion (GloBE) Model Rules of the OECD/G20 Inclusive Framework, commonly described as Pillar Two, establish a minimum effective tax rate of 15 per cent on the profits of large multinational enterprise groups, calculated separately for each jurisdiction in which a group operates. The rules apply to groups with annual consolidated revenue of at least €750 million in at least two of the four preceding fiscal years. Where the effective tax rate on a group’s profits in a particular jurisdiction falls below 15 per cent, a top-up tax is imposed to bring the burden to that floor. For Jamaica, a jurisdiction whose investment policy has for decades rested upon competitive tax incentives, this is not a distant development to be monitored. It is a present consideration with immediate consequences for the multinationals that operate here and for the public revenue.

The mechanics determine which treasury collects

The significance of Pillar Two for a source jurisdiction such as Jamaica lies less in the 15 per cent rate itself than in the order of priority by which the top-up tax is collected. Under the GloBE Rules, where a group’s effective tax rate in a jurisdiction is below 15 per cent, the shortfall is collected first by that jurisdiction if it has enacted a Qualified Domestic Minimum Top-up Tax (QDMTT); failing which it is collected by the jurisdiction of the ultimate parent entity under the Income Inclusion Rule (IIR); and failing that, by other group jurisdictions under the Undertaxed Profits Rule (UTPR). The consequence is straightforward and ought to be stated plainly. If Jamaica taxes the profits of an in-scope group below the 15 per cent floor and has not enacted a QDMTT, the difference does not remain with the taxpayer. It is collected by a foreign treasury. The reduction granted in Jamaica is, in economic substance, transferred abroad.

The compliance obligation is already live

This is not a matter for future planning cycles alone. The first GloBE Information Return (GIR) is due fifteen months after the close of the reporting fiscal year, extended to eighteen months for the transitional first year. For a group with a December year end, the first return covers the 2024 fiscal year and falls due by 30 June 2026. In May 2026 the OECD published further administrative guidance, together with transitional relief from late-filing penalties where a jurisdiction is not yet able to receive return data. That relief is welcome, but it is a concession on penalties and not a deferral of the obligation. Any group within scope that has operations in Jamaica should already have determined where its return is being filed and whether its Jamaican operations are correctly captured within it.

Jamaica’s position: intent signalled, no enactment

Jamaica has signalled its intention to introduce a Qualified Domestic Minimum Top-up Tax as part of its adoption of Pillar Two, and participates in the Inclusive Framework’s pilot programme for developing countries. As matters presently stand, however, no QDMTT has been enacted and no implementation date has been fixed. It is our considered view that this gap, rather than the existence of the global rules as such, is the immediate exposure for Jamaica. Until a domestic top-up tax is in force, the benefit of any sub-15-per-cent effective rate conferred on an in-scope group operating here will, to the extent of the shortfall, accrue to the parent jurisdiction and not to the investor or to the Jamaican fisc.

The tension with Jamaica’s incentive regime

Jamaica’s most significant incentives are precisely the features most likely to depress an effective tax rate below the GloBE floor. The point is best made by reference to the statutory provisions themselves.

By way of illustration:

Paragraph 4(2)(a) of the First Schedule to the Special Economic Zones Act applies a 12.5 per cent corporate income tax rate to an approved occupant, which, after employment tax credits and other reliefs, may yield an effective rate materially below 15 per cent.

The employment tax credit available to Zone occupants further reduces the cash tax borne, and so reduces the GloBE effective tax rate on the relevant profits.

The accelerated capital allowances introduced for new investment in industrial buildings, plant, equipment and information technology in the 2025 and 2026 tax years can depress the effective rate in the very years in which qualifying investment is made.

Where these reliefs reduce an in-scope group’s effective rate in Jamaica below 15 per cent and no QDMTT is in force, the top-up is collected abroad. The incentive then operates to the benefit of a foreign revenue authority rather than to the benefit of the investment it was designed to attract. This is the central implication for both the multinational and the State, and it warrants candid acknowledgement rather than reassurance.

Substance is the mitigant

The position is not, however, one of simple forfeiture. The GloBE Rules provide a Substance-Based Income Exclusion, which removes from the top-up calculation an amount determined by reference to eligible payroll cost and the carrying value of tangible assets in the jurisdiction. The practical effect is that genuine economic presence in Jamaica — real headcount and real plant and equipment — shelters a corresponding portion of profit from the 15 per cent test. For Zone manufacturers and for business process operations with substantial Jamaican payroll, the exclusion may meaningfully reduce, and in some cases eliminate, the top-up exposure. It is our opinion that the exclusion is best understood not as a planning device to be engineered after the fact, but as a recognition, sanctioned by the rules themselves, of investment that is real. Those groups whose Jamaican footprint is substantive have considerably less to be concerned about than those whose presence is thin.

What multinationals operating in Jamaica should do now

Three questions should be addressed, in order. First, is the group within scope, that is, does it meet the €750 million consolidated revenue threshold? Second, if it is within scope, who is filing the GloBE Information Return, and is the 30 June 2026 obligation covered in respect of the group’s Jamaican operations? Third, what is the group’s effective tax rate in Jamaica on the GloBE base, what portion of profit is sheltered by the Substance-Based Income Exclusion, and what therefore is the real top-up exposure? Answering the third question will, for many groups, transform an apparent liability into a manageable and quantified figure, and will identify whether the eventual enactment of a Jamaican QDMTT would alter only the identity of the collecting authority rather than the total tax borne.

What it means for Jamaica

For the State, Pillar Two changes the calculus of tax competition. An incentive that reduces an in-scope group’s effective rate below 15 per cent no longer improves Jamaica’s attractiveness relative to other jurisdictions, because the foregone tax is simply collected elsewhere. The rational response, and the one most jurisdictions in our position are adopting, is to enact a QDMTT so that any top-up attributable to Jamaican profits is retained domestically, while redirecting genuine incentive policy toward measures that survive the GloBE calculation — most notably those rewarding substantive payroll and tangible investment, which the Substance-Based Income Exclusion preserves. Until that legislative step is taken, Jamaica continues to forgo revenue that the rules would otherwise permit it to keep.

We will continue to advise clients on their scope position, their filing obligations, and the modelling of their Jamaican effective tax rate as the domestic legislative response develops. Where a ruling or a representation to the authorities would assist a particular group’s position, we are well placed to pursue it.

We are committed to responsiveness, diligence and integrity.
