You will need to file the form in the following circumstances:
You are filing an original application for a business that is just starting
Your business has been previously registered, but you moved to a new location
You need to amend your application for an already-existing business
You are applying to add a location to an already-existing business
You are applying to receive a Business Registration Certificate
You employ domestic household employees
You are withholding tax income for employees that reside in New Jersey
As you can see, there are multiple circumstances besides registration of a new business. If your previously-registered business was registered with New Jersey rather than another state, you can fill out the REG-C-L form instead. If you need to amend your application, you’ll be asked to provide the reason for the amendment.
