MTR – ETR
where—
MTR |
is the minimum tax rate, and |
ETR |
is the effective tax rate of the jurisdiction for the fiscal year calculated in accordance with section 111AC. |
(3) The jurisdictional top-up tax for a fiscal year shall be the positive amount, if any, calculated as follows:
(TUTP × EP) +ATUJ – D
where—
TUTP |
is the top-up tax percentage for the jurisdiction for a fiscal year determined in accordance with subsection (2), |
EP |
is the excess profit determined for the jurisdiction for a fiscal year in accordance with subsection (4), |
ATUJ |
is the additional top-up tax for the jurisdiction for a fiscal year determined in accordance with section 111AF, and |
D |
is the amount of qualified domestic top-up tax payable for the jurisdiction for the fiscal year. |
(4) The excess profit for the jurisdiction for the fiscal year referred to in subsection (3), is the positive amount, if any, calculated as follows:

where—
NQI |
is the positive amount, if any, of the net qualifying income of all the constituent entities in the jurisdiction determined in accordance with section 111AC(3), and |
SBIE |
is the substance-based income exclusion amount for the jurisdiction for the fiscal year determined in accordance with section 111AE. |
(5) Subject to subsection (6), the top-up tax of a constituent entity for a fiscal year shall be calculated as follows:
JTUT × (QI / AQI)
where—
JTUT |
is the jurisdictional top-up tax for a fiscal year as determined by subsection (3), |
QI |
is the qualifying income of the constituent entity for a jurisdiction for a fiscal year, and |
AQI |
is the sum, if any, of the qualifying income of all the constituent entities for a fiscal year located in the jurisdiction. |
(6) Where—
(a) the jurisdictional top-up tax for a fiscal year is a result of a recalculation to which section 111AF applies, and
(b) there is no net qualifying income in respect of the jurisdiction for the fiscal year,
the top-up tax shall be allocated to each constituent entity using the calculation provided for in subsection (5), based on the qualifying income of the constituent entities in the fiscal year, for which the recalculations pursuant to section 111AF are performed.
(7) The top-up tax of each stateless constituent entity shall be calculated, for each fiscal year, separately from the top-up tax of all other constituent entities.
