Can get a result if you restrict the space, e.g. try Solve[{0 == y - 1/2 Tan[(\[Pi] x)/2], 0 == x - 1/2 Tan[(\[Pi] y)/2], -10 <= x <= 10, -10 <= y <= 10}, {x, y}]

What you have there is a system of transcendental equations that are difficult to solve in general. If you don't mind approximate solutions, you can use FindRoot[] or FindAllCrossings2D[].
