My husband and I are purchasing the company he currently works for. I understand that we will have to obtain new tax id numbers under his and my name. However, how does that work? If his boss technically ownes the name until the final papers are signed and we need to get started on the "prep" work...such as transferring our credit to the vendors, banking, accounting. We want it to be a smooth transition so that the customers receive no delay in service. How do you apply for a tax id number for a business you are purchasing when the seller still ownes the business?
