This is our main tax information forum which deals with topics concerning Canadians living and working in the U.S., U.S. citizens contemplating working in Canada, and all aspects of Canadian and U.S. income tax and related adminstrative issues.
I moved to the US in 2015, but did not sell the holdings in these 2 accounts to get an increased cost basis (bump up?). Is there anything that I can do now, as I am now just completing my 1040 to take advantage of this? Thank you.
No. Your cost basis was established before your arrived.
After 20 years, I am severely cutting back on responses. Do not ask specifically for my help. There are a few others on this board that can answer most questions. All the best
