All your financial decisions are inter-related and therefore you need to consider the consequences of one action on other areas of your finances. Investments may affect your tax liabilities and unexpected expenditure on an overseas property may impact on your liquid savings for retirement income. For example, if you invest £100,000 in a portfolio of collective funds with no structuring to limit tax and you sell them as soon as you make gains, you will be subject to capital gains tax on these investments. The gains from the investments will be reduced by tax without careful planning and any tax efficient investments.
