Umm, of course a business' income can be negative. I have been filing Trader of Securities as a business for many years and being a complete inept trader, I have more years with loss than with positive gain from trading and never had problem with negative loss for efiling until this year. So something changed on field check to disallow negative income, I assume it is on the IRS side since Smart Check was fine. So yeah, have to file by paper this year, suck balls.
