If you incorporate your business, it would not be a separate legal body. Corporations need addresses, and it is preferable for the company’s address to be in the same state as its incorporation for fundability reasons.
Don’t use aged shelf companies from Delaware and Nevada. Don’t use shelf companies that were dissolved and reinstated. Don’t use addresses that involve a UPS Store or MailboxEtc., or a careless virtual office.
Obtain a shelf company from New Mexico, Colorado, Montana, or other state where the business owners are not reported on the public record. This is important so you’re respected as the first and original owner.
