I do know that between the two of us, even converting my spouses' income to USD, we'd still be below the standard deduction for joint filing, but it would bring our income up to the required for getting healthcare coverage for myself, which is why we discussed and decided that was the way to go since them being Candian they have healthcare in their Country already, but I didn't qualify for the ACA due to low threshold for being married, but would with the combined income for joint.
So, I know nothing of my income would change, it would just be declaring joint and then inputting their income in the correct places as far as I can tell based on what I've read so far.
And as far as I know, they only have work income, their bank account total was less than required for reporting (if I read it correctly, there was a specific limit before you had to report them).
I think at most they might have a small amount of unearned income from investments, but I'm not sure if that's setup as a trust for them by their grandparents of if it's in their name, but I'd assume that would be simple to add into the foreign income if there's a spot for that.
I'm still learning how it works reading over everything, but I think in terms of income for them it's work only and maybe some small investment income, but they are getting that info for me, that may not even be in their name it may be a trust type thing setup for them.
So, until I find out otherwise, I'm going with that it's just income from work and how to get the deduction since they are already taxed in Canada, the only other thing they get that I know of is some taxes back a few times a year, but I don't think that's income since that's from the Canadian government, but I could be wrong on that one.
I do appreciate all the help though, definitely filling in the blanks with how to best approach it.
