I find myself in the unenviable position of having to run payroll, this afternoon, for all my employees. I have never run payroll before, nor do I have access to any software that runs payroll. I have a theoretical understanding of taxes and withholdings, but that is all. I know it is possible to run payroll without software, but googling leads me only to advertisements for payroll software. I really need a set of step by step instructions. I am in Colorado, which I am sure makes some kind of difference.
