TL;DR

Five things to take forward. Business combinations put deferred tax straight into goodwill. Share-based payment can split one award across two statements. A history of losses demands real evidence, not a forecast. Uncertain tax positions are tax balances, never provisions. And Pillar Two currently gets no deferred tax at all — by design, not by oversight.

Key terms in plain English

Carrying amount
The value an asset or liability is shown at on the balance sheet right now.
Fair value
The price you would get for selling an asset (or pay to transfer a liability) in a normal deal between market participants today.
Other comprehensive income
A separate section below profit for certain gains and losses, like revaluations, that don't go through the main profit figure.
Deferred tax
Tax that today's accounting numbers commit you to paying (or saving) in a later year, because the books and the tax rules recognise things at different times.
Temporary difference
A gap between an item's value in the accounts and its value for tax that will reverse in future.
Tax base
The value the tax authority gives an asset or liability.
Provision
A liability where the amount or the timing is uncertain, like a likely legal settlement.
Goodwill
The extra a buyer pays for a business above the fair value of its identifiable net assets, such as reputation and expected synergies.

Full explanation

Overview

Two identical acquisitions. One books seventy-five thousand more goodwill — over a number nobody negotiated.

Part one was the mechanics. Part two is where deferred tax actually shows up — revaluations, pensions, share schemes, group accounts — and the one live rule the IASB had to build a special exception for.

Straight into goodwill

When Meridian buys a company, it fair-values the target's assets — but the tax base of those assets does not move with it. One acquired asset gets fair-valued to eight hundred thousand euros; its tax base, unchanged, stays at five hundred thousand. That gap of three hundred thousand is a taxable temporary difference, and the resulting deferred tax liability — seventy-five thousand euros — does not go through profit or loss at all. It goes straight into GOODWILL.

One award, two homes

Share-based payment splits in a way almost nothing else does. Meridian's cumulative IFRS 2 expense on a share award is two hundred thousand euros. But the tax authority's future deduction is based on the share price at exercise — today, that would be two hundred and eighty thousand. The tax effect of the two hundred thousand goes to profit or loss, fifty thousand. The tax effect of the EXTRA eighty thousand — twenty thousand — goes straight to equity. One award, one deferred tax asset, two different homes.

Two more sources, and then the one everyone in a group structure needs to know.

A temporary difference from exchange rates alone

Where a non-monetary asset's tax base sits in a different currency from your functional currency, retranslating that tax base at each year end creates a temporary difference from EXCHANGE RATES ALONE — even though the asset itself is never retranslated under IAS 21. That deferred tax movement goes through profit or loss, because it didn't come from an OCI or equity item in the first place.

€30,000, only in the consolidated accounts

Sell inventory from parent to subsidiary at a twenty percent markup, and if the subsidiary hasn't resold it externally by year end, consolidation eliminates that unrealised profit. But the PARENT already paid real tax on it, in its own jurisdiction. On a hundred and twenty thousand euros of unrealised profit, that is a thirty-thousand-euro deferred tax asset in the consolidated accounts — assessed entity by entity, jurisdiction by jurisdiction.

Tax follows the item , every time

And two sources you already know from this channel, now filed correctly. A revaluation surplus under IAS 16, and a defined benefit remeasurement under IAS 19, are both recognised in OTHER COMPREHENSIVE INCOME — so their deferred tax sits in OCI too. An IAS 40 fair value gain, and an IAS 37 provision, both run through profit or loss — so their deferred tax does too. Tax follows the item, every time.

All of that assumes there's future profit to use the asset against. When there isn't, the bar gets a lot higher.

€600,000 if recognised in full

Meridian's subsidiary Newco has just posted its third consecutive annual loss. Tax losses carried forward: two million four hundred thousand euros. Recognised in full, that is a six-hundred-thousand-euro deferred tax asset. But a history of recent losses raises the bar — you need either sufficient existing taxable temporary differences, or genuinely convincing other evidence. A management forecast alone is NOT enough. A secured contract, or a firm order book, might be.

A tax balance, never a provision

Uncertain tax positions get their own rulebook. IFRIC 23 asks whether it is probable a tax authority accepts your treatment; if not, you measure the effect using whichever better predicts the outcome — the single most likely amount, or a probability-weighted expected value. And a settled point worth repeating: an uncertain tax position is presented as a tax asset or liability. Never as an IAS 37 provision — even though both standards use the word probable.

Now the one live rule — a genuine global first, and the IASB had to write an exception just to buy time.

A mandatory exception

The OECD's Pillar Two rules set a fifteen percent minimum effective tax rate for large multinational groups, jurisdiction by jurisdiction. Working out the deferred tax consequences of a brand-new global tax system, country by country, was judged too complex to demand immediately — so in May twenty twenty-three the IASB introduced a MANDATORY temporary exception: no deferred tax is recognised or disclosed on Pillar Two legislation, even once it is enacted. Entities still disclose their CURRENT tax exposure, and — before the legislation even takes effect — what is reasonably estimable about it.

One last question, now that all these numbers exist. Where do they actually land on the statement?

The one category with no judgement

From January twenty twenty-seven, IFRS 18 gives income tax its OWN mandatory category — with zero classification judgement involved. Every other category on the statement can shift between operating, investing or financing depending on the entity's main business activity. Income tax never does. It sits after financing, and the statement runs straight through to profit for the period.

Always non-current

One presentation rule survives every one of these sources. Under a classified balance sheet, ALL deferred tax is non-current — regardless of how soon the underlying temporary difference actually reverses. And two deferred tax balances offset only with a legally enforceable right to do so, against the SAME tax authority.

Carrying amount vs tax base, every time

Nine sources, one rule connecting all of them: find the gap between carrying amount and tax base, then check where the ITEM itself landed — profit or loss, other comprehensive income, or equity — because the tax follows it there. Get that right, and every deferred tax number on a real set of accounts traces back to a paragraph you now know.
