Approximately 10,000 watercraft are registered in the surrounding states to Kansas residents to avoid the 30% property tax rule. Watercraft includes boats, jet-skis, canoes, sailboats, etc. Drive around a marina or place that stores boats and see how many tags are Kansas. I think it's pathetic that if I signed a waiver saying I operated the boat over 50% of the time in Oklahoma that I would save $1,500 bucks a year.
