Accounting profit and GloBE income: understanding the difference

A finance team asked for its Pillar Two position usually reaches for the profit figure it already reports. That figure is the starting point, but the GloBE rules then adjust it, and the adjusted number is what the minimum rate is tested against.

The same is true on the tax side. The tax charge in the accounts is not the same as adjusted covered taxes, and the statutory corporate income tax rate is not the effective tax rate the rules calculate.

GloBE income is built for each constituent entity from its financial accounting net income, determined under the accounting standard the ultimate parent uses to prepare the consolidated financial statements, and before the consolidation adjustments that eliminate transactions between group entities.

That single sentence carries a lot of work. Entities reporting locally under a different standard may need to be restated. Figures that exist only after consolidation, or only in a local statutory account, are generally not the right input. Groups that discover this late often find the data gathering, rather than the calculation, is the long part of the project.

From that starting point the rules add back net tax expense and make a series of defined adjustments: excluded dividends and excluded equity gains and losses, fines and penalties above a threshold, prior period errors and changes in accounting principle, and an election for the treatment of stock-based compensation, among others.

The effect is not cosmetic. A holding company whose accounting profit is largely dividend income from subsidiaries can have very little GloBE income once excluded dividends are removed, while an entity with modest accounting profit can have more. The jurisdictional result is what counts: GloBE income and covered taxes are combined for all the group’s entities in a jurisdiction, so one entity rarely tells the story.

The numerator of the effective tax rate is adjusted covered taxes, not the tax line in the accounts. It includes current tax on covered income and a deferred tax amount, with deferred tax recast at the minimum rate where the local rate is higher, and with defined exclusions and adjustments.

Timing is where this becomes practical. Deferred tax liabilities that do not reverse within the prescribed period can be subject to a recapture rule, which requires an earlier year to be recalculated. A group that treats deferred tax as an accounting detail tends to be the group that has to reopen a prior period later.

A jurisdiction with a headline rate above 15% can still produce an effective tax rate below it, through incentives, exempt or partially exempt income, credits, timing differences or losses. A jurisdiction with a low headline rate may test above 15% once the calculation is done.

This is why a jurisdiction is assessed rather than assumed. The statutory rate is a reason to test, in either direction; it is not a conclusion.
