Apply the IAS 21.9 primary indicators first: the currency that mainly influences the entity's sales prices, the currency of the country whose competitive forces and regulations mainly determine those prices, and the currency that mainly influences labour, material, and other costs. Use the IAS 21.10 secondary indicators (the currency in which financing is generated and in which operating receipts are usually retained) and, for a foreign operation, the IAS 21.11 factors only as supporting evidence when the primary indicators are not decisive. Functional currency is a matter of fact, not a free choice; where the indicators are mixed, management applies judgement and gives priority to the primary indicators.
Complete the functional currency assessment under IAS 21.9-12 before any translation into the presentation currency.

Presentation currency is the currency in which the financial statements are presented, and IAS 21.38 permits an entity to present in any currency. It is distinct from functional currency, which is determined by fact under IAS 21.9; a group commonly presents in a single currency even though its subsidiaries have several functional currencies, which requires translation on consolidation. Document the election and the reason for any presentation currency that differs from the functional currency (IAS 21.53), and apply it consistently across all periods presented.
Document the presentation currency election and its translation policy under IAS 21.38 before finalizing the statements.

When functional and presentation currency differ, IAS 21.39 requires assets and liabilities to be translated at the closing rate at the reporting date, income and expenses at the rates at the dates of the transactions (a period average is acceptable only when it approximates the actual rates), and the resulting exchange difference to be recognized in other comprehensive income. Translate equity components at historical rates. The common error is applying an average or closing rate uniformly to every line, for example translating income and expenses at the closing rate or restating equity, which distorts the translation reserve.
Translate assets and liabilities at the closing rate under IAS 21.39(a) and recalculate the balance sheet translation.
Official guidance: IFRS issued standards
Exchange differences arising on translating a foreign operation into the presentation currency are recognized in other comprehensive income and accumulated in a separate foreign currency translation reserve within equity (IAS 21.32; IAS 21.39(c)). Test whether the item is a translation difference on a foreign operation (OCI) or an exchange difference on the entity's own foreign-currency monetary item (profit or loss, IAS 21.28), because the two are frequently confused. The cumulative reserve stays in equity and is reclassified to profit or loss only on disposal or partial disposal of the operation (IAS 21.48).
Reclassify the foreign operation translation differences from profit or loss to OCI and the translation reserve under IAS 21.39(c).
Official guidance: IFRS issued standards
At each reporting date, remeasure foreign-currency monetary items (cash, receivables, payables, and loans) at the closing rate and recognize the exchange difference in profit or loss in the period it arises (IAS 21.23(a); IAS 21.28). Non-monetary items carried at historical cost are not retranslated, and those carried at fair value use the rate at the date fair value was measured (IAS 21.23(b)-(c)). The trap is routing these entity-level monetary differences to OCI, which is reserved for translating a foreign operation into the presentation currency.
Remeasure foreign-currency monetary items at the closing rate with the differences in profit or loss under IAS 21.28.
Official guidance: IFRS issued standards
Test functional currency at each reporting date for a genuine change in the underlying transactions, events, and conditions. A change in functional currency is applied prospectively from the date of the change (IAS 21.35), translating all items at that date's rate and treating the translated non-monetary amounts as historical cost (IAS 21.36). Do not restate comparatives for a functional currency change; only a change in presentation currency is applied retrospectively.
Complete the functional currency change assessment and, if a change occurred, apply it prospectively from the change date under IAS 21.35.
Official guidance: IFRS issued standards
A change in presentation currency is a change in accounting policy applied retrospectively under IAS 8.19, so each period presented is re-translated into the new presentation currency using the IAS 21.39 method and comparatives appear as if the new currency had always been used. Contrast this with a change in functional currency, which is prospective (IAS 21.35) and does not require comparative restatement. Confirm the direction of the change before deciding whether comparatives move.

Temporary differences can arise when the tax base of a foreign operation's net assets differs from the translated carrying amount. Under IAS 12.61A the tax follows the underlying item, so deferred tax on differences recognized in OCI is itself recognized in OCI, while entity-level exchange differences that IAS 12.41 charges to profit or loss are treated in profit or loss. Reconcile the OCI deferred tax to the translation reserve movement.
Recognize or reallocate deferred tax on the translation-related temporary differences to OCI under IAS 12.61A.

First determine whether the foreign operation's functional currency is that of a hyperinflationary economy, using the IAS 29.3 indicators, notably a cumulative inflation rate approaching or exceeding 100 percent over three years. If so, restate its financial statements to the measuring unit current at the reporting date under IAS 29 before translating every amount, including comparatives, at the closing rate into the presentation currency (IAS 21.42-43). The error is translating unrestated hyperinflationary results, or translating non-monetary items at historical rates, both of which understate the amounts.
Apply IAS 29 restatement to the hyperinflationary operation before translating into the presentation currency (IAS 29.8; IAS 21.43).

Verify that the consolidation tool applies the closing rate to all balance sheet items, transaction-date or approximating average rates to income and expenses, and historical rates to equity, with the net exchange difference posted to the translation reserve as the balancing entry (IAS 21.39). Reconcile the reserve movement and confirm that goodwill and fair value adjustments arising on acquisition of a foreign operation are treated as assets of that operation and translated at the closing rate (IAS 21.47). The trap is a system configured with a single rate across all statements, or one that fails to translate goodwill, leaving the reserve unable to reconcile.
Correct the consolidation translation rates and recalculate the translation reserve and goodwill translation under IAS 21.39 and IAS 21.47.
Official guidance: IFRS issued standards
IAS 21.52 requires disclosure of the amount of exchange differences recognized in profit or loss (other than those on financial instruments measured at fair value through profit or loss) and the net exchange differences recognized in other comprehensive income and accumulated in the translation reserve, with a reconciliation of that reserve from opening to closing balance. Tie the rollforward to the statement of changes in equity and the OCI statement. The trap is presenting a closing reserve balance without the movement, which prevents users and auditors from tracing cumulative differences by period.
Add the exchange difference disclosure and the translation reserve rollforward required by IAS 21.52.

The accounting policy note must state the functional currency of the entity and each significant operation, the presentation currency where it differs from the functional currency together with the reason for using a different one, and a description of the translation methods applied (IAS 21.53). Include the treatment of goodwill and fair value adjustments, which are translated at the closing rate as assets of the foreign operation (IAS 21.47). The trap is a boilerplate policy that omits the reason for a different presentation currency or the goodwill translation basis.
Functional and presentation currency translation is applied and disclosed under IAS 21.39, IAS 21.52, and IAS 21.53. Complete the currency and translation method disclosure in the accounting policies under IAS 21.53.
