I am holding common shares of Diageo, a British company quoted in GBP currency ( https://finance.yahoo.com/quote/DGE.L/ ) that I purchased several years ago. Recently I initiated the ADR Conversion of those shares into the corresponding American Depositary Receipt (ADR), Ticker-Symbol:DEO.
In addition to the handling fee that my broker charges, I was also told that there will be a charge for "Stamp Duty Reserve Tax" for this ADR conversion in the amount of 1.5% of the value of the shares converted. (FWIW I found this info about this levied tax: https://www.sec.gov/Archives/edgar/data/806968/000119312505222886/dex2.htm ).
Can I add this Stamp Duty Reserve Tax to the cost basis of my ADRs?
