Claiming amount for partner on line 30300

Hi everyone,

Looking for some advice as I haven’t been able to find much online for my particular situation. I’m currently filing my partner and I’s 2025 return and I’m uncertain if I can claim the amount on line 30300. I’d obviously like to since it’ll increase my return by almost 2.5k but I also want to make sure I’m able to so I can avoid a potential audit from doing it wrong.

My partners income was technically $0 for the year however he is a PhD student with a very decent scholarship. Because of this I don’t fully support him, we mostly split our bills, however he would not be able to afford food, rent etc without us splitting all the bills. Does this count as supporting your spouse? Their income was definitely below my basic personal amount because his scholarships are all non-taxable income and his line 23600 is $0. I’m just not sure about the second qualification of “supporting my partner” as it feels vague in its description.

Any advice is appreciated!
