How is forex trading taxed in the UK?

What is forex trading?

Forex trading refers to the conversion of one currency to another in the hope of making a profit. For example, if you believe the pound will strengthen in value compared to the US dollar, you could sell some dollars in exchange for pounds with the view of buying back those dollars at a later date, hopefully at a lower price.

Currencies are always traded in pairs, so when you buy one (base currency) you sell another (quote currency).

Forex is the world’s largest financial market. With no centralised exchange, it’s very accessible and can be traded almost 24/7 so you can get exposure to rising and falling currency values around the clock.

It’s worth noting, however, that the forex market is often volatile and while this creates trading opportunities, it also exposes you to greater risk so you could gain or lose money faster than expected.

How is forex trading taxed in the UK?

How forex trading is taxed depends on the instrument you choose to trade it with. In the UK, the most accessible way to trade forex is through spread bets and CFDs.

These derivative products are taxed differently from one another. The main distinction being the treatment of capital gains tax (CGT). For most people, spread betting is tax-free so you’re not required to pay any tax.¹

With CFD trading however, profits may be subject to CGT. The rate at which you pay is dependent on your income. If you’re a basic rate taxpayer, you’ll pay 10% and if you’re in a higher threshold you’ll pay 20%.

If forex trading is your secondary form of income, the first £1000 of profit is tax-free.¹

It's also important to note that tax laws are subject to change and differ depending on individual circumstances and the country you live in.

Forex trading tax example

Here’s an example of how you could be taxed when trading forex in the UK. It’s based on the assumption that you believe that the pound will rise against the US dollar and, where applicable, you’re exempt from CGT and stamp duty.

Because you believe GBP will rise against USD, you decide to buy GBP/USD. This means you’ll profit if the pound does rise against the dollar.
