It sounds like you are the secretary / treasurer of the company. If this is true your "job title" alone makes all those records available to you. I would first contact the cpa get all records and then find a new CPA.

Second, as an owner of the company with more then 20% you have rights to all records of pretty much everything. Anything and everything that goes on in that business you the right to know. You dont have veto power, but you knew that already.

Good luck.
