Individual stocks should not be a problem on a US return. The purchase price will have to be calculated in £s and the selling price in £s so exchange rate swings will probably be more volatile than the share price. I do this in reverse selling US shares.
Any dividends should be converted to £s on the date the dividend is paid out and will get the lower tax rate in the US as well as in the UK.
When completing the appropriate IRS forms then name the stock along with the ticker symbol.
Any HMRC taxes can be offset against IRS taxes on those same shares using a foreign tax credit.
Thanks larrabee and Durhamlad!
Yes, larrabee, I suspect you are right. Any of us who got the invitation will probably be checking it out.
Durhamlad: It's a UK stock, so the purchase (and eventual sell) price will already be in £s, as well as any dividends. I assume you meant I'd need to convert to dollars for IRS reporting purposes? At what point would I make each conversion? At the time of purchase and sell, and on receipt of dividends, or December 31 Oanda rate, or some other calculation heretofore unknown to me?
I'll probably keep a spreadsheet for this, and I need to know what to track.
So far, I've only had to file 1040s and FBARs, as most of our assets are in my husband's name. What additional IRS forms would this kick up?
