(Olympia, WA)  --  Democratic lawmakers in Washington are proposing a 20-percent tax for businesses that gross more than a quarter-million dollars annually.  Some of those businesses include daycare centers, such as Mini-Skool in Lacey.  Director Mugsy Schumacher tells KING-5 the school has already raised tuition rates twice in the last year to cover cost-of-living increases and a minimum wage-hike.  Schumacher says daycare rates will rise again if the tax passes.
