With many online stockbrokers offering these days easy access to shares listed on foreign stock exchanges many investors may be paying unnecessary amounts of dividend withholding tax by not claiming back excess deductions or not having filled out the correct paperwork prior to investment.

Once you start receiving dividends, as a UK tax payer, you will usually need to declare this on your self-assessment tax return. You may find that you will be charged tax twice: in the country of origin and in the UK.
