Moved to USA from Canada in May 2025
Hello, I moved to the USA in May 2025 as a green card holder.
I am unsure about the rules for filing a full-year return versus a dual-status return. Since I am unable to file a dual-status return through TurboTax online (there is no where I can indicate my move date), does this mean I need to report all income on a full-year return, including the period from January to April?
If so, would this result in double taxation for that period, given that I also filed a final return in Canada? I understand that foreign tax credits may be available for the non-resident period, but I am unclear how to determine those amounts, particularly since deemed dispositions were reported on departure.
Would it be acceptable not to report income earned from January to April if none of it was U.S.-source income?
I want to ensure I am complying with the rules, but I would appreciate guidance on the most appropriate approach that would be acceptable to the IRS.
Thank you very much in advance for your assistance.
