Deductions & credits

Hi, George: Re whether or not for a Sole Proprietor filing Sch. C needs to report the Payroll Tax Credit as an expense on Sch. C after claiming this credit on Form 6765, please refer to, in the thread Kristina K's example for corporation using Form 1120 to reduce corporate expenses after receiving the R&D credits. If we do, and the corporations need to, the R&D credits will defeat the purpose by losing its benefit. Isn't it? Thanks! changli
