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.
US citizen (husband), GC holder (wife), resident in Canada, haven't filed US tax returns for several years. Are now filing past 1040's. How far can they file back to collect the child tax credit of previous years.
They need to file three to be compliant. IRS only allows three year back to collect a credit.
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
