Standard disclaimer etc. but you may want to defer your filing and use this opportunity to load some losses into this year, which you can offset against any future gains. Also, it is rarely zero. You have interest on savings and money that you have spent in the process of working on your startup. You may want to account all the money you have spent so far and load it as a debt on your company - giving you a big negative number on your personal tax. In short, don't put zero - because it isn't.
