CFM10522 - Currency transactions and accounting: pre IAS transactions n other currencies

Transactions in other currencies

This guidance describes the post-FA 2002 taxation of loan relationships, derivative contracts and FOREX.

As described at CFM10521, a UK-resident company which accounts in a non-sterling currency can submit foreign currency accounts to HMRC and, under FA93/S93, compute its corporation tax profits or losses in its reporting currency. In the same way, a non-resident company which is chargeable to CT on the profits of a UK branch can submit to HMRC a return of accounts for the branch in the company's reporting currency, and compute taxable profits in that company.

But to draw up those accounts (or return of accounts for the UK branch) the company still has to translate into its reporting currency any receipts, expenses, assets or liabilities that are denominated in some other currency (including sterling). Exactly the same principles apply here as in the case of a company that accounts in sterling ( CFM10511). The exchange rate that the company uses in its accounts also applies for tax purposes, provided that it is an arm's length rate for the relevant day.
