[Organizers] registration with the state

Hi all, A question for bookkeepers / treasurers: Are you a nonprofit group registered as such with state,  filing the appropriate regular tax returns with the state? We (Queen City Contras, in Burlington, Vermont) receive a nice corporate donation every year, partly because we are a 501c3 with IRS, through CDSS.  But we have not registered with the state. Here is the problem: Our bank has stopped accepting checks payable to our dance group, because regulations require that we have a business account, using a business name that is registered with the state. Thanks, -Brian Appleberry
