@ xavier 
beacuse of inert pair effect , by this effect nuclear attraction increase on s electron , so, that 
it doesnot participate in oxidation process , 
thatswhy the +5 oxidation state decrease down the group .

It is due to inert pair effect.It is the reluctance of valence s-shell effect due to the penetration of heavy sub shell. Hope it clears
