@Hal_Al @xmasbaby0 , thank you for your feedback but you didn't misread. My daughter and grandchildren are living in another house, different physical address than where I live & have been since 2018, solely because where I live is not large enough to accommodate them (otherwise they would be at same address with me). Premise of the tax law assumes one living in another house would be paying separate mortgage or rent expenses on their own, but this is not the case here. I own the house daughter & grandkids are living in free & clear, no mortgage, I pay all taxes, upkeep, utilities, etc. I also pay 85% of daughter & kids living expenses. My adult daughter & her children pay no rent to me or anyone else for occupying the property. Given the financial support facts, it does not make sense that I could only claim the grandchildren for Child Tax Credit if we live at the same physical address - why would that matter? Purpose of the qualification test would seem to be whether I pay for their housing and living expenses, which I do. I can find no rationale for why same physical address would qualify while separate address would not, with all other financial support factors being exactly the same. Definition of "living with you" is ambiguous in the tax law verbiage, & the basis for my original question.
