The guidance provides two additional 'guiding principles' in determining whether a minimum tax is functionally
equivalent to the GloBE Rules and therefore qualifies as a QDMTT. The minimum tax must (1) be consistent with
the design of the GloBE Rules; and (2) provide for outcomes that are consistent with the GloBE Rules.
Generally, QDMTT computations will require the same data points as the GloBE Rules. However, the guidance
allows f or variation in design, stating “[s]ome degree of customisation of a QDMTT in each jurisdiction is to be
expected” and “[v]ariations in outcomes between the minimum tax and GloBE Rules will not prevent that tax from
being treated as a QDMTT if those variations systemically produce a greater incremental tax liability.” The guidance
notes that a QDMTT is not required to have a substance-based carveout or de minimis income exception; if it does,
it cannot be more expansive than those exceptions permitted under the GloBE Rules.
The guidance notes that the IF will consider providing further guidance on the information collection and reporting
requirements under a QDMTT. The guidance also states that the IF will work on a 'QDMTT safe harbour' measure
and a multilateral review process for assessing countries’ QDMTTs.
B. CFC taxes
To be a Qualified Domestic Minimum Top-up Tax, the regime must exclude tax paid or accrued by domestic
constituent entities (CEs) with respect to the income of foreign CEs under its own CFC regime. A jurisdiction under
a QDMTT regime can go even further and exclude all taxes that it imposes on a f oreign CFC or hybrid entity.
QDMTTs must also generally exclude cross-border taxes paid by a CE owner under a CFC regime that are
allocable to a domestic CE, as well as taxes paid by a main entity that are allocable to a permanent establishment
located in the QDMTT jurisdiction.
Observation : In practice, this means that a QDMTT will apply first (i.e., before CFC allocations and application of
the IIR or UTPR). For countries that adopt a QDMTT, any allocation of taxes paid under GILTI will not be taken into
account when determining the local QDMTT liability. The guidance notes that this approach would remove the need
f or “the complex calculations required in some cases to allocate CFC taxes… to be reported to a jurisdiction that
implements a QDMTT.” It will be important to clarify whether a QDMTT will be creditable for US foreign tax credit
(FTC) purposes. Further, for US taxpayers that are 'excess GILTI credit,' this ordering rule is expected to result in
double taxation as none of the additional QDMTT is expected to be creditable in the United States against the
GILTI tax liability (normally arising from expense apportionment).
Observation: While there could be a tendency to view the GloBE Rules as impacting only large MNE Groups (e.g.,
those with revenue over the EUR 750 million threshold), a QDMTT can be applied to small MNE Groups and to
purely domestic groups. The QDMTT guidance explicitly provides that “the application of a QDMTT could be
extended to groups whose UPE is located in the jurisdiction but that are not within the scope of the GloBE Rules
because their revenues are below the EUR 750 million threshold … [f]urthermore, a QDMTT could also apply to
purely domestic groups, i.e. groups with no foreign subsidiaries or branches.”
III. Allocation of taxes arising under a Blended CFC Tax Regime (e.g., GILTI)
Article 4.3.2(c) of the GloBE Rules require the allocation of some CFC taxes from the CE-Owner that is subject to a
CFC regime to the CFC that gave rise to the CFC charge. However, a specific methodology is not prescribed and
the Commentary states that CFC taxes should be allocated based upon a CE’s share of the underlying income.
The guidance clarifies how CFC taxes should be allocated when such taxes are generated under a 'Blended CFC
Tax Regime.' This is a CFC tax that is “computed based on a blend of income, losses and / or creditable taxes of
multiple CFCs whose ownership interests are held by a constituent entity-owner (or multiple constituent entity-
owners that f ile a single tax return)”. The guidance specifically confirms that GILTI, in its current form, meets the
def inition of a CFC Tax Regime under the GloBE Rules. The guidance also states that GILTI is an example of a
