I have S-Corp for last 8 years. First few years i used professional and all went fine he filed 1120s and 1040 for me. But last 3 years i did it myself and did a huge mistake i did not file 1120s and filed only 1040 as sole proprietor. Even though i am only employee in my s-corp but was reading that i needed to file 1120s anyways. Can someone please suggest what to do? I still have to file 2015 taxes should i file them as 1120s?
