i held baltimore tech adr shares with an account in USA
the company was liquidated this year
can i offset this loss against any gain
when you make returns for capital gains do you have to provide proof of gains/loss.
i would appreciate any advice on this matter
I'm sure that you can utilise the losses against future gains (to leave you in a no gain/no loss situation at best), I'm not sure if there is a timeframe (I don't think that there is) in which you have to utilise losses (it's been a while since I did tax).
Wrt to records, I don't think you have to submit receipts etc., but I'm sure you should keep them for at least 5 years or so just in case there are any queries.
