1. 1 Using link analysis to develop indirect and multi-tiered ownership structures Larry R. May Intelligent Business Solutions Group June, 2012

2. 2 Enterprise structures are an attempt to identify all economic activity under the common control of a taxpayer. Currently limited to flow-trough relationships, parent/subsidiary links, and primary/secondary SSN associations. Also limited to structures with at least two business returns. What is an Enterprise?

3. 3 What is common control? Control is direct and indirect ownership of 50% or more of another entity consistent with the rules set forth in IRC section 267(c) and section 707(b). Allocation proportions are used as a proxy for ownership percentage. Other items which may assist in identifying related parties include name similarities, TIN sequencing, common address and common preparer.
