Capital gains tax or income tax - forex trading

What's the difference between capital gains tax and income tax? Which of the two does retail forex trading fall under?

Forex Trading for the purposes of making a profit and not to hold as an investment will be treated as revenue, i.e. the same as if you are employed and earning a salary. Capital Gains tax is part of Income Tax, but it's taxed at a different rate. So the actual difference is between revenue and capital which both makes up income tax.
