The GloBE computation requires more data per entity than any prior international tax calculation. Four distinct source documents feed the engine, each covering a different aspect of the GloBE framework. Most Pillar Two project delays happen at the data collection stage — not the calculation stage. Understanding what each artefact contains, and where it typically comes from, is the starting point for a workable data collection process.
Artefact 1: Consolidation Pack
The Consolidation Pack (or trial balance) is the primary source of GloBE Income under Art. 3.1. It contains the profit and loss account — revenue, expenses, and net income — for each constituent entity, drawn from the financial statements used for group consolidation.
In practice, this typically comes from the group's consolidation system (SAP BPC, Hyperion, OneStream) as a packaged export. The key fields are: revenue, cost of sales, operating expenses, finance income/expense, and profit before tax. The entity-level trial balance is needed — consolidated or jurisdictional aggregates are not sufficient for the Art. 3.2 adjustments.
Common gap: entities that are excluded from the group consolidation (e.g. securitisation vehicles) may still be GloBE constituent entities. Check the Art. 1.3 exclusions carefully before deciding which entities to include.
Artefact 2: Tax Provision
The Tax Provision is the primary source of Adjusted Covered Taxes under Art. 4.1. It contains: current tax expense, deferred tax expense (and the underlying temporary differences that drive it), the applicable statutory tax rate, uncertain tax positions (UTPs), and any prior year adjustments.
The deferred tax expense needs special handling: under Art. 4.4.1, deferred tax balances must be recast at 15% — deferred tax recorded at rates above 15% is reduced; deferred tax at rates below 15% is excluded. The provision must therefore contain both the deferred tax amount and the rate at which it was recognised.
Common gap: groups that maintain tax provisions at a consolidated or regional level, rather than per entity, will need to disaggregate the provision before it can be used in the GloBE computation.
Artefact 3: Adjustments Schedule
The Adjustments Schedule contains the Art. 3.2 memo items that the trial balance cannot supply. The most common items are:
- Excluded dividends (Art. 3.2.1(b)) — dividends received from subsidiaries that are excluded from GloBE Income
- Stock-based compensation (Art. 3.2.2) — the difference between the financial accounting charge and the tax deduction amount
- Pension adjustments (Art. 3.2.4) — IAS 19 remeasurements excluded from GloBE Income
- Asymmetric FX gains/losses (Art. 3.2.5) — currency movements on intercompany balances denominated in a different functional currency
- Revaluations under fair value accounting (Art. 3.2.6)
This schedule is often the most time-consuming artefact to prepare, as it requires input from both the financial reporting team and the tax team.
Artefact 4: SBIE Schedule
The SBIE Schedule feeds the Substance-Based Income Exclusion under Art. 5.3.3. It contains: eligible payroll costs per entity (wages, salaries, employment taxes for employees performing activities for the CE) and the net book value of tangible assets (property, plant and equipment, averaged over opening and closing balance).
Common gap: payroll attributable to capitalised development costs must be excluded. Groups with significant internal software development or R&D capitalisation will need to split payroll between expensed and capitalised elements before completing this schedule.
