rather than me cut and paste the instructions for who must file, I'll provide a link to them and then once you determine what category you fall into, if any, you can post back providing such additional info as needed to determine if you have to file. based on the 1% you are not a category 1 or 2 filer, but with category 3 if that 1% was $100K yes you have to file, category 4?. you can also use your browser's search engine for more info on who must file.
