Hi Sixto Olson,
No. Capital gains tax and income tax are two separate taxes that never mix.
The dividends paid each year, were treated as income and taxed as income.
Disposing of the shares can create a capital gain subject to capital gains tax or a capital gains loss.
You will need to convert all parts of the capital gains calculation into pounds sterling, using the exchange rate in force
at the time the shares were purchased and sold.
The official exchange rate can be found at
Exchange rates from HMRC in CSV and XML format.
Archived exchange rates can be found at
Foreign exchange rates and spot rates: 1 January 1989 to 31 March 2009
Thank you.
