Ind AS 21: Tax Effects, Disclosures and Differences from IAS 21
Updated 5 October 2026 · Fact-checked
Under Ind AS 21, tax on exchange differences follows Ind AS 12: tax goes to profit or loss if the exchange difference is in profit or loss, and to OCI if the exchange difference is in OCI. You then disclose exchange differences, the equity reserve reconciliation and currency facts. Know how Ind AS 21 relates to IAS 21.
Understand Tax Effects, Disclosures and Differences from IAS 21
Exchange differences arise when foreign currency items are settled or reported at rates different from those at which they were first recorded. Ind AS 21 decides where the difference goes: profit or loss for transaction differences on monetary items, and OCI (foreign currency translation reserve, FCTR) for translation of a foreign operation into the presentation currency. The cumulative FCTR is reclassified to profit or loss on disposal of the foreign operation.
Tax follows the item. Ind AS 21 does not have its own tax rules. It says that the tax effects of exchange differences are accounted for under Ind AS 12. So if the exchange gain or loss is in profit or loss, its current or deferred tax is also in profit or loss. If the exchange difference is in OCI, the related tax is in OCI. This is the principle of backward tracing.
Deferred tax arises when the tax law taxes or allows an exchange gain or loss in a different period from the books, for example only on settlement. That creates a temporary difference. On translating a foreign subsidiary, Ind AS 12 lets you skip a deferred tax liability on the translation difference in the net investment if the parent controls the timing of reversal and reversal is not probable in the foreseeable future.
Disclosure is the second half of the topic. You must disclose exchange differences recognised in profit or loss (other than those on financial instruments measured at FVTPL under Ind AS 109), the net exchange differences in OCI with a reconciliation of the separate equity component, and facts about functional and presentation currency. Examiners may also ask how Ind AS 21 relates to IAS 21, so know the one carve-out clearly.
On IAS 21, remember that Ind AS 21 largely follows IAS 21: exchange differences on monetary items go to profit or loss. The key difference is para 46A of Ind AS 21, a carve-out from IAS 21. It deals with long-term foreign currency monetary items recognised in the financial statements for the period ending immediately before the beginning of the first Ind AS reporting period. For these items, exchange differences may be accumulated in a Foreign Currency Monetary Item Translation Difference Account (FCMITDA) and amortised, instead of going straight to profit or loss.
Keep this separate from Ind AS 101 para D13AA. That is a first-time adoption exemption. It lets a first-time adopter continue its previous GAAP policy for exchange differences on long-term foreign currency monetary items recognised before the beginning of its first Ind AS reporting period. Para 46A sits in Ind AS 21. Para D13AA sits in Ind AS 101. For a hyperinflationary functional currency, Ind AS 21 refers to Ind AS 29, as IAS 21 refers to IAS 29. Always confirm the exact wording in the study material for your attempt.
Key rules to remember
- Tax follows the item
- Tax on an exchange difference is recognised where the exchange difference is recognised
- Profit or loss item gives profit or loss tax. OCI item gives OCI tax. Applied through Ind AS 12.
- Deferred tax on timing difference
- Deferred tax = Exchange difference × Applicable tax rate
- Use it when tax is allowed or charged only on settlement. A deferred tax asset needs probable future taxable profit.
- Exchange difference on a monetary item
- Foreign currency amount × (Closing rate − Rate at initial recognition or last reporting date)
- Use the rate at initial recognition, or the rate at the last reporting date if the item existed then. Taken to profit or loss for monetary items. For a liability, a rise in rate is a loss.
- FCTR reconciliation
- Closing reserve = Opening reserve ± Net exchange difference in OCI for the year
- Disclosure requires opening and closing balances of the separate component of equity. Show the reconciliation. The cumulative amount is reclassified to profit or loss on disposal of the foreign operation.
- Exchange difference disclosure in profit or loss
- Disclose exchange differences recognised in profit or loss, other than those arising on financial instruments measured at FVTPL under Ind AS 109
- Differences on instruments at fair value through profit or loss are outside this disclosure, as para 52(a) of Ind AS 21 provides.
- Currency disclosures
- Disclose: presentation currency differs from functional currency, reason, and any change in functional currency with reason
- Also disclose convenience translations as supplementary information with the currency and the method of translation.
How to solve Tax Effects, Disclosures and Differences from IAS 21 questions
Use this order for any question on tax, disclosure or differences from IAS 21. It keeps you in provision-facts-conclusion form.
- 1Identify the item: a monetary item in a transaction, or the translation of a foreign operation. This decides profit or loss versus OCI.
- 2Compute the exchange difference using foreign currency amount multiplied by the change in rate. Mark it gain or loss.
- 3Check the tax law treatment: is the difference taxed or allowed on accrual or only on settlement? A mismatch creates a temporary difference.
- 4Compute deferred tax at the enacted or substantively enacted rate. Check recoverability before recognising a deferred tax asset.
- 5Place the tax with the item. Profit or loss exchange difference gives profit or loss tax. OCI exchange difference gives OCI tax. Apply the subsidiary exemption in Ind AS 12 only if its conditions are met.
- 6List the disclosures: exchange differences in profit or loss other than those on FVTPL instruments, OCI differences with reserve reconciliation, and currency facts.
- 7If the question asks about IAS 21, state it in one line: Ind AS 21 largely follows IAS 21 and takes monetary item differences to profit or loss, but retains para 46A as a carve-out for long-term foreign currency monetary items (accumulated in FCMITDA and amortised). Mention separately that Ind AS 101 para D13AA is the first-time adoption exemption on the same subject.
- 8Write the conclusion with the amount and the account affected.
Quickest way: Three-line check for tax and disclosure questions
When to use it: Use it when time is short, especially in the 30% case-scenario MCQs.
- Ask where the exchange difference sits: profit or loss or OCI. Put the tax in the same place.
- Multiply the difference by the tax rate only if a temporary difference exists. Otherwise no deferred tax.
- For disclosure, remember two numbers (profit or loss amount, OCI reserve reconciliation) and two currency facts (reason for presentation currency, reason for change in functional currency).
- For IAS 21, remember: Ind AS 21 largely follows IAS 21 but retains para 46A as a carve-out for long-term foreign currency monetary items. Ind AS 101 para D13AA is the separate first-time adoption exemption.
Common mistakes in Tax Effects, Disclosures and Differences from IAS 21
Taking tax on an OCI exchange difference to profit or loss.
Students treat tax as always a profit or loss item.
Fix: Apply tax follows the item. If the exchange difference is in OCI, the related tax is in OCI.
Recognising a deferred tax asset on an exchange loss without checking future taxable profit.
Students stop after multiplying the loss by the tax rate.
Fix: State that the asset is recognised only to the extent that future taxable profit is probable, and say so in the answer.
Including exchange differences on FVTPL financial instruments in the profit or loss disclosure of exchange differences.
Students read the disclosure as total exchange differences.
Fix: Disclose exchange differences recognised in profit or loss other than those arising on instruments measured at fair value through profit or loss under Ind AS 109.
Leaving out Ind AS 21 para 46A when asked for the key difference from IAS 21, or mixing it up with Ind AS 101 para D13AA.
Students assume Ind AS 21 is identical to IAS 21, or treat the two paragraphs as one rule.
Fix: Say Ind AS 21 retains para 46A as a carve-out from IAS 21 for long-term foreign currency monetary items (accumulated in FCMITDA and amortised). Then distinguish it from Ind AS 101 para D13AA, the first-time adoption exemption.
Forgetting the reconciliation of the foreign currency translation reserve.
Students give only the year's OCI amount.
Fix: Always show opening balance, movement for the year, and closing balance.
Recognising deferred tax on translation differences of a subsidiary without testing the exemption.
Students apply deferred tax mechanically to every temporary difference.
Fix: Check whether the parent controls the timing of reversal and reversal is not probable in the foreseeable future. If so, no deferred tax liability.
Worked examples
Example 1
Alpha Ltd (functional currency INR) took a USD 1,00,000 loan on 1 December 2026 when the rate was ₹83. The closing rate on 31 March 2027 is ₹85. Under the tax law, the exchange loss is allowed only when the loan is repaid. The tax rate is 25.17%, and Alpha expects sufficient taxable profit in future. Show the accounting.
Show the solution
- The loan is a monetary liability, so the exchange difference goes to profit or loss.
- Exchange loss = USD 1,00,000 × (85 − 83) = ₹2,00,000.
- The tax law allows the loss only on settlement, so a deductible temporary difference of ₹2,00,000 arises.
- Deferred tax asset = ₹2,00,000 × 25.17% = ₹50,340.
- Future taxable profit is probable, so the asset can be recognised.
- The exchange loss is in profit or loss, so the deferred tax credit also goes to profit or loss under Ind AS 12, as Ind AS 21 directs.
Answer: Recognise an exchange loss of ₹2,00,000 in profit or loss and a deferred tax asset of ₹50,340 with the credit in profit or loss. The net effect on profit is ₹1,49,660.
Example 2
Beta Ltd presents INR financial statements. Its foreign subsidiary uses USD as its functional currency. During the year, total exchange differences in profit or loss are ₹4,00,000, of which ₹1,50,000 relates to derivatives measured at FVTPL. The foreign currency translation reserve opened at ₹12,00,000 (credit) and the translation gain for the year taken to OCI is ₹3,50,000. Beta controls the timing of any reversal and reversal is not probable in the foreseeable future. State the exchange difference disclosures and the tax position on the translation gain.
Show the solution
- Disclose exchange differences in profit or loss other than those on FVTPL instruments. The ₹1,50,000 on FVTPL derivatives is outside this disclosure, so the amount to disclose is the remaining ₹2,50,000 of the ₹4,00,000.
- The OCI exchange difference is accumulated in the foreign currency translation reserve.
- Reconciliation: opening ₹12,00,000 + translation gain ₹3,50,000 = closing ₹15,50,000.
- Ind AS 12 allows no deferred tax liability on the temporary difference from the net investment in the subsidiary when the parent controls reversal timing and reversal is not probable in the foreseeable future. Both conditions are met.
- So no deferred tax is recognised on the ₹3,50,000 OCI gain, and no tax is shown in OCI on it.
- Beta's presentation currency equals its own functional currency (INR), so no presentation-currency disclosure arises for Beta. The subsidiary's USD functional currency is handled by translation into INR.
Answer: Disclose ₹2,50,000 as exchange differences in profit or loss (other than those on FVTPL derivatives) and a reserve reconciliation from ₹12,00,000 to ₹15,50,000. No deferred tax is recognised on the translation gain.
Exam tips
- In written answers, state the Ind AS 12 link in one line: tax on exchange differences follows the item to profit or loss or OCI.
- For disclosure questions, list items with numbers: profit or loss amount, OCI amount with reconciliation, then the currency facts.
- For IAS 21 questions, say Ind AS 21 largely follows IAS 21 but retains para 46A as a carve-out for long-term foreign currency monetary items. Then distinguish it from Ind AS 101 para D13AA, the first-time adoption exemption.
- In case-scenario MCQs, look for FVTPL derivatives or a tax-on-settlement clause. They usually decide the answer.
- There is no negative marking for MCQs, so always attempt every option-based question.

Tax Effects, Disclosures and Differences from IAS 21: frequently asked questions
How are tax effects of exchange differences treated under Ind AS 21?
Ind AS 21 sends you to Ind AS 12. Tax on an exchange difference is recognised in the same place as the difference: profit or loss or OCI. Deferred tax arises when the tax treatment timing differs from the books.
What is the relief for long-term foreign currency monetary items?
Ind AS 21 retains para 46A, a carve-out from IAS 21. For long-term foreign currency monetary items recognised before the beginning of the first Ind AS reporting period, exchange differences may be accumulated in FCMITDA and amortised. Separately, Ind AS 101 para D13AA lets a first-time adopter continue its previous GAAP policy for such items. Check your study material for the exact wording.
What must be disclosed under Ind AS 21?
Disclose exchange differences recognised in profit or loss, other than those arising on financial instruments measured at FVTPL under Ind AS 109. Disclose net exchange differences in OCI with a reconciliation of the separate equity component. Also disclose the reason when presentation currency differs from functional currency and the reason for any change in functional currency.
Is Ind AS 21 the same as IAS 21?
It is largely the same, including its reference to Ind AS 29 for hyperinflationary functional currencies. The key difference is para 46A of Ind AS 21, which allows exchange differences on certain long-term foreign currency monetary items to be accumulated and amortised. Do not confuse it with the first-time adoption exemption in Ind AS 101 para D13AA.
