I started a corp 4 years back to run a business from home. I never actually used the corp for anything because I just couldn't fit it in to my life. 4 years later I still have this corp and I simply want to close it out. I never file any returns for the 4 years I had it because I never use it. My question is do I file for those years and if so how? And how do I close it once and for all?
