Background

Some abusive tax avoidance transactions (ATAT) encountered by revenue officers are designed to appear, and often are, quite complex and involve various transactions as well as numerous entities including trusts, partnerships, corporations, limited liability companies and offshore entities. These transactions and multiple or layered entities are often used by a taxpayer to make it difficult to identify and locate assets or income sources.

Research and investigation of ATAT cases does not entail techniques or tools unique to ATAT casework; however, some techniques are more commonly applied, such as use of the collection summons to follow income flow or to determine nominees, and nominee/alter ego/transferee relationships regarding title to assets.

Potential fraud indicators may be present in ATAT cases. Contact your local fraud enforcement advisor, when appropriate.

Research to identify the nature of the promotion or transaction used by a taxpayer is important in developing an effective case strategy for resolution of ATAT cases.

Research prior to contact is essential in ATAT cases. Guidance on conducting an initial analysis is located in IRM 5.1.10, Taxpayer Contact. Additional research may be necessary due to the complexity of an ATAT case. Because the goal of ATAT schemes is often to disguise the taxpayer’s beneficial ownership of assets, developing a complete and accurate financial picture of a taxpayer participating in an abusive scheme is crucial.

Awareness of taxpayer rights is remains important in ATAT case work. Taxpayer rights, as identified in Pub 1, Your Rights as a Taxpayer, are addressed in IRM 5.1.9, Collection Appeal Rights, and throughout IRM Part 5.

Reports from the Embedded Quality Review System (EQRS) measure program consistency, effectiveness in case actions and compliance with policy and procedures. Trends from these reports are used to recommend improvements where necessary when errors are identified. Reports from EQRS provide management information used in guiding revenue officers to take timely, effective, and appropriate case actions.

Program Effectiveness:

Collection Policy performs ATAT program reviews as necessary to verify compliance with IRM requirements and address Treasury Inspector General for Tax Administration (TIGTA) and Government Accountability Office (GAO)audit findings.
