Keep in mind you need to file as a business this form as well on or before that date. The sooner you focus on this in the new year, the better off you'll start that year without a headache.
In short, no. You need no one else to make this form. It all depends on how complex your business is with your employees, but these types of documents are pretty templated and straightforward with us. We made sure to have each section vetted by our own internal tax attorneys, so it will be like filling out a real W-2 for the IRS every time, whether for yourself or your employee.
