CFM10508 - Currency transactions and accounting: a brief history of the legislation

The legislative history of the taxation of foreign currency transactions

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

The table below gives a brief history of the tax rules dealing with currency transactions and currency accounting, and how they have evolved over the last decade. For details of the specific guidance that applies to APs beginning before 1 October 2002, please see the relevant instructions in the CT manual.

CT14030Before FA 1993Before FA 1993, there was virtually no statute law on foreign currency issues. Case law had established that corporation tax is a sterling tax in the sense that returns of profits are required to be made in sterling. Case law, particularly Pattison v Marine Midland (57TC219) established some guidelines, but disputed issues remained.

A company which accounted in a non-sterling currency had to translate its accounts into sterling in order to compute its profits chargeable to Corporation Tax.
CT13620+FA 1993FA93/S92 laid down the general rule that a company must compute its trading profits in sterling, and Chapter 2 Part 2 FA 1993 (the FOREX legislation) gave rules for the computation of exchange gains and losses on monetary assets, including the exchange rate to be used on translation.

Local currency rules allowed a company to follow its accounts treatment where the profits or losses (but not capital allowances) of a trade carried on by an overseas branch were translated into sterling using the closing rate/ net investment (CR/NI) method (see CFM8xxx), but it had to elect to compute the branch profits in the local currency.

The local currency rules also allowed companies that did not account in sterling to compute their trading profits (but not capital allowances) in the local currency, if they elected to do so.
CT14000+FA 2000A new system applied to APs beginning on or after 1 January 2000, and ending after 20 March 2000.

The rules on overseas branches were extended to apply to business (rather than just trade) profits and losses, and to include capital allowances. The requirement for an election was abolished.

These changes also applied to companies that draw up accounts in non-sterling currency.
CFM10510+FA 2002For APs beginning on or after 1 October 2002, there have been changes to link the tax treatment of both currency transactions and currency accounting closer to accounting practice.

On currency transactions, FA93/S94AAnow sets out the exchange rate to be used where FA93/S92 applies. FA 2002 also assimilated exchange gains and losses on monetary items into the loan relationship and derivative contract rules.

A new section, FA93/S93A, was inserted into FA 1993 to set out more specific provisions for cases where a company (or a UK branch) uses the CR/NI method to incorporate the results of a part business into its accounts. Exchange rates to be used in these cases are given by FA93/S94AA.

FA93/S93 now deals wholly with currency accounting - the cases where a company (or a UK branch) prepares local currency accounts. *
