Can forex trading (UK) be a full-time job?

  • 3 min read
  • Last updated 11 Feb 2025

If you start forex trading (UK), you need to make sure that you’re doing it at volumes that can support your livelihood. It’s the same with any other pursuit that you take on freelance. You have to ensure that you have enough business (and income) to do it full-time.

What is forex trading?

Let’s start from the beginning. Forex trading is basically foreign currency exchange. You bet on the movement on currencies to make a profit. And as so many currencies are very volatile when it comes to the movement in their value, the space is very popular for traders. 

The two popular methods of trading are:

  1. Derivative products
    • Spread betting
    • CFD trading
  2. Via a forex broker

Why start forex trading (UK)?

Unlike your standard 9-5, the forex market is open 24/7. This means that you can easily dabble in it during your spare time before you take it on full-time. Another advantage is that it’s a very accessible pursuit. You can start forex trading from you phone, laptop – and all from your sofa. 

Here’s a list of other features that make forex trading attractive to take on full-time:

  • Lots of resources online to learn how to trade forex
  • High profits (although high risk)
  • Low transaction costs
  • Big selection of currency pairs to choose from
  • It’s decentralised – the market isn’t owned by one central power

Are there disadvantages?

There are disadvantages to going freelance, in any industry. The lack of stability is the major disadvantage and one that’s even more pronounced when you’re just starting out. When it comes to forex trading specifically, the risk can be significant.So it’s not something that you should give up the day job for without ample research and preparation. 

Another risk in forex trading is that fraud is rife in the space. Not every broker will have your best interests at heart so it’s very wise to tread carefully. 

Tax implications of forex trading

Working as a full-time investor will mean that you’re responsible for paying your own taxes. You’ll have to do this via a tax return after the end of each tax year. There are potentially three types of tax that you might owe

1. Income Tax

This is he tax that we all have to pay on our earnings when we earn more than the Personal Allowance.
