Tax Affairs Organization Issues New Directive on Currency Conversion Rate for Imports Without Currency Transfer

According to Boursenews, in a report published Saturday, August 8, 2026 (17 Mordad 1405), the head of Iran's Tax Affairs Organization issued a directive to tax offices nationwide setting out how to determine the currency conversion rate in tax reviews of imports made without a currency transfer. Under the directive, the primary basis for calculating an imported good's cost is the rate recorded in the taxpayer's supporting documents, such as contracts and remittance orders, and only when valid documents are missing does the National Iranian Exchange's selling rate on the relevant date apply. The directive also states that if the required currency is later supplied by the central bank or another authorized body after the goods arrive, the tax effects of that supply must be calculated at the time of the review.
