Copy of their id. To prove age. Copy of a recent bill to prove they are alive. Bank statement showing you sent money to them. The statement to prove you sent them money is kind of bs. I’ve provided a statement showing me sending money from my Taiwan acc to my foreign account before. I’ve heard of people arguing that they don’t need to provide proof they sent money because Taiwanese don’t need to prove they gave money to their parents to get the deduction.
I wonder, can step parents also be listed as dependents, and is there a maximum number of dependents one could have? Both my parents re-married, so with my wife’s parents too, I could potentially list 6 parental dependents.
