"Shani is an enormous young talent in Swiss football who, without a doubt, will have a great future," Everton boss Roberto Martinez told the club's official website.
"We're delighted to have found a young player who believes that our club is the perfect step for him to enhance his quality and to grow his career.
"He fits in really well to our style and the way we want to play the game. He is a family boy, hungry and he is desperate to fight for his place in our talented young squad."
Tarashaj has scored eight goals in 18 games for Grasshoppers this season.
He told evertontv: "It is a dream for me to sign here at Everton. I am proud and so happy to be here."
