@Kat271 , so from your post and recognizing that Canada ( like many countries ) is pretty much residency based tax regime. Therefore once you have become a resident of US ( deemed Non-Resident at GreenCard definitely but K-1 may also qualify for Canada purposes), at the earliest date you were legally in the USA -- see -- Residency starting and ending dates | Internal Revenue Service.
(a) Thus for your form 1040 , you are recognizing only US income ( per your post -- all US income were post entering US ) -- this is your world income. So I do not understand why you have to deal with foreign income/ foreign tax etc. ( I am assuming that your post was describing your total income );
(b) Assuming that you plan to file MFJ, we would run into an issue . Because your residency start date is April 8th 2024, you must use itemized deduction -- you do not meet the requirement for an entire calendar year. So if your spouse does meet the entire calendar year requirement, generally there is no mechanism to have one partner as standard and the other as itemized.
Am I missing something here ?
I do recognize my colleague @DaveF1006 's post and agree as to what he is saying but I am still stuck with "there is no foreign income / tax" to consider as I read your post.
Please excuse , if I am reading your post wrong.
