[ASKKPOP] G-Dragon's yearly royalties from songwriting revealed on 'One Night of TV Entertainment'

This particular broadcast featured a special corner which explored many thingsBig Bang-related, including the reasons for the group's fandom--attributed to their addictive music and vocal ability (perhaps their good looks and humor, as well?). The segment also focused on the fact that Big Bang make their own music, which led to the talk of how much G-Dragon makes for writing the songs. 

Taking into account that songwriting is only one of many activities that fills GD's deep coffers, the revelation doesn't come as much of a surprise.
