Currency Translation: How to Avoid Booking Profit You Never Earned

When the exchange rate can move several fold within one fiscal year, translation stops being a technical year-end entry. It decides whether your company reports profit or loss, and what it pays tax on. This note is for finance managers in importing, exporting and foreign-currency-borrowing businesses.

The core problem: profit that exists only on paper

A translation gain brings no cash into the company. It still enters taxable income and it still influences dividend decisions. The result is a situation I have seen repeatedly: a company reporting healthy book profit that has to borrow in order to pay the tax on it.

The cause is usually a classification error rather than a sophisticated financial decision. Businesses that revalue every foreign currency balance at year end are effectively converting exchange rate inflation into revenue. Fixing that costs nothing but care.

Monetary versus non-monetary

Iranian accounting standard 16 on the effects of changes in foreign exchange rates carries the whole logic in one sentence: monetary items are retranslated at the balance sheet date, non-monetary items carried at historical cost are not.

A monetary item is a right to receive, or an obligation to deliver, a fixed or determinable amount of money. If what changes hands at maturity is cash, it is monetary. If it is goods or services, it is not.

Choosing the rate

Multiple official and market rates have made translation one of the most disputed lines in Iranian tax assessments. The professional standard is to use the rate at which the entity genuinely obtains currency or settles obligations, and to be able to evidence it.

Three things that have worked in practice when defending a file:

1. Approve the rate basis once, in writing, as part of the company's accounting policies, and keep the board minute.
2. Repeat the same basis in later years. Consistency matters more than the rate itself.
3. Disclose the basis and the resulting gain or loss explicitly in the notes to the financial statements. What is disclosed is not treated as concealment.

Tax treatment

Two rules need to be kept apart.

Translation losses. Paragraph 24 of Article 148 of the Direct Taxes Act treats them as allowable expenses under accepted accounting principles, provided a uniform method is applied across years. The condition is about consistency, not about the loss itself. A company that books a translation loss one year and switches method the next year, when the rate has moved in its favour, hands the assessor the reason to disallow it. The general conditions for expense deductibility are covered in allowable tax expenses.

Translation gains. In principle these are income of the period and enter taxable income even when unrealised. Temporary provisions have applied to particular sectors in some years, so check the current circular rather than relying on precedent.

Year-end procedure

1. Extract every foreign currency balance from the ledger; if currency balances are not separated in your chart of accounts, fix that first.
2. Split each balance into monetary and non-monetary, recording the reason for the classification.
3. Agree each monetary balance to bank documents and counterparty confirmations.
4. Take the approved rate at the balance sheet date and file a printed copy of the source.
5. Compute the difference item by item, not as a single aggregate entry.
6. Book gains and losses in separate accounts so they remain traceable in the return.
7. List non-monetary items in the working paper marked "not retranslated" so it is clear they were considered.
8. File the summary with your year-end closing documentation.

Management implications

If translation gains are not separated from operating profit, performance analysis becomes meaningless. A manager who credits a currency jump to sales efficiency will see an apparent collapse the following year while nothing in the business has changed. Keep a distinct line for FX effects in internal reporting; the broader logic is in inflation and financial statements.

The second implication is dividends. Distributing profit that arose from unrealised translation drains working capital. I usually recommend computing distributable profit after removing the translation effect, even where the law does not require it.

Key takeaways

• Only monetary items are retranslated; revaluing inventory, fixed assets or advances manufactures phantom profit.
• Consistency of method and documentation of the rate carry more weight in an audit than the rate chosen.
• Translation losses are allowable subject to consistent method; gains are in principle taxable when unrealised.
• Keep FX gains and losses in separate accounts for clean analysis and a clean return.
• Strip out unrealised translation effects before deciding on distributions.
