Yes and no. According to my CPA accountant, starting in tax year 2011, you were to report cash and credit card sales separately. However, the IRS has backed off on this rule(due to lots of small business complaints) and likely won’t enforce it this year. What the IRS is doing is they are requiring credit card companies to 1099 businesses, and then comparing these numbers to the businesses credit card sales figures. They are especially scrutinizing restaurants with this program. The problem is that the 1099 numbers from CC companies includes tips and tax so the numbers aren’t so easily compared. My CPA said that his tax software company sent out a memo telling him to disregard the separation of cash from CC sales for tax year 2011. The separation of sales may be a firm requirement next year.
