If you pump the water in at the bottom of the tank; yes. You have to consider the whole continous height of the water.
If, for example, you have a 4 feet tall tank standing on a platform 10 feet up, and pump in water at the bottom, the lifting height for the pump will be 10 feet when the tank are empty, and 14 feet when the tank are full. If you have the hose from the pump at the top of the tank, the height will ofcourse be 14 feet.
