Long term capital gains tax on forex investments can be a tricky subject to understand. As a general rule, taxes are due when profits from forex trading exceed 600 EUR in a year. While it is possible to reduce or even eliminate your taxes using certain exemptions or deductions, investors must be careful not to make mistakes when filing taxes on their forex trades. Factors such as the duration of the trade, your nationality, and the type of transaction must all be taken into account. Staying informed of the changing tax policies in your country and with the currency pair you are trading is essential in order to make sure you remain compliant.
