This is a new Safe Harbour included in the January 2026 OECD Side-by-Side Tax Package (see: Tax Challenges Arising from the Digitalisation of the Economy – Global Anti-Base Erosion Model Rules (Pillar Two), Side-by-Side Package) that deems the top-up tax for a jurisdiction to be zero insofar as it relates to ‘Qualified Tax Incentives’ (QTIs).
The Top-up Tax that relates to QTIs is the difference between:
(i) the Top-up Tax for the jurisdiction calculated with the amount of QTIs used in the year being added to covered taxes (subject to a cap), and
(ii) the Top-up Tax if the SBTI Safe Harbour election hadn’t been made.
A QTI is defined as a generally available tax incentive calculated based on expenditure incurred, or on the amount of tangible property produced in the jurisdiction.
The SBTI Safe Harbour is to apply from fiscal years beginning from January 1, 2026.
Aside from the main election for the SBTI Safe Harbour to apply, the detailed rules for this contain two additional elections.
Tax Credits Election (Art 4)
An MNE group can make an annual election to treat a Qualified Refundable Tax Credit or a Marketable Transferable Tax Credit as a QTI.
Substance Cap Election (Art 4)
The substance cap referred to above for determining the amount added to covered taxes is generally 5.5% of the higher of (1) Eligible Payroll Costs in the jurisdiction or (2) the depreciation and depletion recorded in FANIL for Eligible Tangible Assets located in the jurisdiction.
However, an MNE group can make a 5 year election for the jurisdiction for the substance cap to be 1% of the carrying value of Eligible Tangible Assets located in the jurisdiction (excluding land and other non-depreciable assets) for that Fiscal Year
