Understanding the Core: Investment Taxes Explained

What Are Investment Taxes?

Investment taxes are levies applied to the earnings you make from various assets such as stocks, bonds, mutual funds, ETFs, property, and other investments. Types of taxable investment income include:

• Capital Gains: Profits from selling an investment for more than you paid.
• Dividends: Earnings distributed by companies to shareholders.
• Interest Income: Earnings from savings accounts, bonds, and other fixed-income products.

Why Are They Important?

Every pound paid in unnecessary taxes is a pound lost from your future wealth. By understanding the rules and applying strategic planning, you can significantly minimise the impact of taxes on your investment returns.
