In fiscal 2010, La Mesa-based Comic-Con took in $10.1 million—mostly from the sale of membership “badges.” As a nonprofit educational corporation “dedicated to creating awareness of, and appreciation for, comics related popular art forms,” it doesn’t sell tickets. It also doesn’t pay taxes—. But it also brings in as much as $60 million to the San Diego economy, according to one estimate. Does it deserve tax-exempt status? Or would that threaten its super-draw?
