Allowable Business and Owner Type Diagram
The following diagram shows the restriction on business types during submission and possible combinations. Many of these restrictions come directly from ETRAN. Even so, some of the business types are less restrictive than best practices.
We encourage vendors to follow proper business law when determining Owner types and whether you should enter SSN or an EIN for an entity.
For example, entering an SSN is allowed for an LLC. However and EIN is more appropriate here except in the case of a single-member disregarded entity where no EIN has ever been established.
