Are Foreign Exchange Gains and Losses Taxable? BIR Rules Under RMC No. 12-2024
Only a realized foreign exchange gain or loss — one that comes from a closed and completed transaction, such as actually collecting a foreign-currency invoice or repaying a foreign-currency loan — is taxable income or a deductible expense for Bureau of Internal Revenue (BIR) purposes. An unrealized gain or loss, the kind that shows up only when a foreign-currency-denominated asset or liability still outstanding at year-end is restated at a new exchange rate, is neither taxable nor deductible. Revenue Memorandum Circular (RMC) No. 12-2024 is the BIR issuance that clarifies this distinction.
This post explains the realized-versus-unrealized line, how foreign currency amounts are converted to Philippine peso, and where the resulting gain or loss goes on the income tax return.

RMC No. 12-2024, issued by the BIR on January 22, 2024, clarifies the accounting and tax treatment of foreign currency transactions for both financial reporting and internal revenue tax purposes. It sets out how a taxpayer should record and disclose foreign exchange transactions when preparing financial statements and when reporting income and deductions to the BIR, so that the two sets of books are not treated as automatically interchangeable for tax purposes.
The circular responds to a practical problem: accounting standards require foreign-currency assets and liabilities to be restated at the closing rate at every reporting date, which produces a book gain or loss even when no cash has moved. RMC No. 12-2024 addresses whether that book-level movement is also a tax event, and answers that it is not, unless the underlying transaction has actually closed.
What is the realized-versus-unrealized distinction? #
The core distinction is whether the foreign exchange gain or loss comes from a transaction that has actually closed, or merely from restating a balance that is still open. A realized gain or loss arises from a closed and completed transaction — the foreign currency has actually been received, paid, or otherwise settled. An unrealized gain or loss arises from remeasuring a foreign-currency-denominated asset or liability that remains outstanding at the reporting date; it is a paper fluctuation, not an amount anyone has collected or paid.
- Realized gain or loss: Comes from a closed and completed transaction, such as collecting a foreign-currency receivable or repaying a foreign-currency loan. It is taxable income (gain) or a deductible expense (loss).
- Unrealized gain or loss: Comes from period-end restatement or remeasurement of a foreign-currency asset or liability still outstanding at year-end. It is not taxable income and not a deductible expense.
- Substantiation: A realized foreign exchange gain or loss must be substantiated with sufficient evidence showing it arose from a closed and completed transaction — proof of actual receipt, payment, or settlement, not just a journal entry.
| Feature | Realized gain/loss | Unrealized gain/loss |
|---|---|---|
| Trigger | Transaction actually closes (collection, payment, settlement) | Period-end restatement of a balance still outstanding |
| Taxable/deductible for BIR purposes | Yes | No |
| Evidence needed | Proof the transaction closed | None required for tax purposes — it has no tax effect |
| Where it appears | Income tax return (other income or itemized deductions) | Financial statements only (book entry) |
How is foreign currency converted to Philippine peso? #
A foreign currency transaction is converted to Philippine peso using the exchange rate at the time the related asset, liability, income, or expense is recognized or remeasured, with the spot rate on the transaction date used for initial recognition. This means the peso value first recorded on an invoice, loan drawdown, or similar transaction uses the exchange rate prevailing on that transaction date. Any later remeasurement, for financial-statement purposes, uses the rate applicable at that later date — but as explained above, that later remeasurement does not itself trigger a tax consequence unless the transaction has closed.
Where does a realized forex gain or loss go on the income tax return? #
A realized foreign exchange gain is reported as part of other taxable income, while a realized foreign exchange loss is reported as part of ordinary allowable itemized deductions. This placement matters for return preparation: the gain or loss is not reported as a separate line item with its own tax rate, but folded into the ordinary computation of taxable income alongside the taxpayer’s other income and deduction items. Attachments supporting the figures, such as proof that a receivable was collected or a loan was repaid, should be kept on file in case the BIR asks for substantiation.
Worked example: realized gain on collection vs. unrealized year-end restatement #
A single invoice can illustrate both sides of the distinction — the same receivable produces an unrealized book adjustment at year-end and a realized, taxable gain only once it is actually collected. The figures below are fictional and for illustration only.
Pacific Freight Forwarders Inc. invoices a United States client USD 50,000 in November, when the exchange rate is ₱56 per USD. The company books a receivable of ₱2,800,000 (USD 50,000 × ₱56).
At the company’s December 31 fiscal year-end, the USD 50,000 receivable is still uncollected. For financial-statement purposes, the company restates the receivable at the December 31 closing rate. That restatement produces a book gain or loss, but because the receivable has not actually been collected, it is an unrealized amount — not taxable income, and not reported on the income tax return for that year.
In January, the client pays the invoice in full. The company receives USD 50,000, converted at the prevailing rate of ₱58 per USD, for ₱2,900,000. Comparing the ₱2,900,000 actually received to the ₱2,800,000 originally booked produces a ₱100,000 difference. Because the transaction has now closed — the cash has actually been collected — this ₱100,000 is a realized foreign exchange gain, taxable as part of other taxable income in the year of collection (here, the following year, when payment was received).
| Event | Date | Rate used | Peso amount | Realized or unrealized? |
|---|---|---|---|---|
| Invoice issued, receivable booked | November | ₱56/USD | ₱2,800,000 | — (initial recognition) |
| Year-end restatement, still uncollected | December 31 | Closing rate at year-end | Book adjustment only | Unrealized — not taxable |
| Client pays in full | January | ₱58/USD | ₱2,900,000 | Realized gain of ₱100,000 — taxable |
The same logic applies in reverse to a foreign-currency loan: restating an outstanding loan balance at year-end produces an unrealized, non-deductible book loss or gain, while actually repaying the loan at a rate different from the drawdown rate produces a realized, deductible loss or taxable gain.
Frequently asked questions #
Is a foreign exchange gain always taxable income? #
No. Only a realized foreign exchange gain — one that arises from a closed and completed transaction, such as actually collecting a foreign-currency receivable — is taxable income. An unrealized gain from simply restating a still-outstanding foreign-currency balance at a new exchange rate at period-end is not taxable.
What is the difference between a realized and an unrealized foreign exchange gain or loss? #
A realized foreign exchange gain or loss comes from a transaction that has actually closed, such as collecting a receivable or paying off a loan in foreign currency. An unrealized gain or loss is a book or paper fluctuation that appears only when a foreign-currency-denominated asset or liability still outstanding at year-end is remeasured at a new rate, with nothing actually collected or paid.
Can I deduct an unrealized foreign exchange loss on my income tax return? #
No. An unrealized foreign exchange loss, such as one that appears only from restating an outstanding foreign-currency liability at year-end, is not a deductible expense for BIR income tax purposes. Only a realized loss, substantiated as arising from a closed and completed transaction, may be deducted.
What issuance governs the tax treatment of foreign exchange gains and losses? #
Revenue Memorandum Circular No. 12-2024, issued by the BIR on January 22, 2024, clarifies the accounting and tax treatment of foreign currency transactions for both financial reporting and internal revenue tax purposes, including how realized and unrealized foreign exchange gains and losses are recorded and disclosed.
Where does a realized foreign exchange gain or loss appear on the income tax return? #
A realized foreign exchange gain is reported as part of other taxable income, and a realized foreign exchange loss is reported as part of ordinary allowable itemized deductions, on the taxpayer’s income tax return.
Summary #
RMC No. 12-2024 draws a clear line for taxpayers who deal in foreign currency: a foreign exchange gain or loss is a tax event only once the underlying transaction actually closes. Year-end restatement of a still-outstanding foreign-currency receivable or liability produces an unrealized, non-taxable, non-deductible book figure; collecting or paying that same amount later produces a realized gain or loss that belongs on the income tax return, as other taxable income or as part of ordinary allowable itemized deductions. Keep evidence that a transaction actually closed before treating any forex movement as taxable or deductible.
