Remove the bolts and nuts which connect the tank to the bowl as well as the lines for water distribution. After this, it'll be simple to take the tank off. If there's an elbow that runs between the bowl and the tank then you must get rid of it first. 

Then, remove the screws used to fix the tank onto the walls. Take extra attention and keep the tank securely in your hands so that it does not fall when it is removed away from wall.

The next step is to take off the bowl that is fixed to the floor using bolts and nuts. The bolts are typically hidden beneath caps. You can remove by placing an screwdriver under the caps, and pushing them upwards.
