The answer is no. Each business was established with its own identification number, and that is how IRS
expects the results to be reported; by taxpayer number.
They can't be combined. Even a merger or other sale/purchase could not include the results before merger into one taxpaying entity combined income and expense.
If you were correcting an error, you might be able to do what you suggest. Let's say that the Schedule C business was open for years, and the new corporation, designed to replace it, was opened 1/1/2012. Both entities would still have identification numbers, and separate banking. Let's go further, and assume that some 2012 business was deposited in the old schedule c bank account, and checks drawn as well.
I could see filing the corporation return reporting
all the income and expense, but the schedule c business would have to file as well, reporting the items that went through its bank account. I could then add a line item for the net results as an adjusting gain or loss, noted as "received by ABC Services, Inc.". This would allow the schedule C reporting of net income
of $0, and filing of a final schedule C result.
