Why write thank you and not thanks you?
As George M. Cohen would reply:
"I thank you, my sister thanks you, and my parents thank you."
Apart from "I thank you" :
singular person - use 'thanks' - my cousin thanks, my uncle thanks you
persons in the plural -use 'thank' - my cousins thank you, my aunts thank you.
