Offshore Compliance Initiatives Overview

  1. The Offshore Compliance Initiatives (OCI) office promotes voluntary compliance with U.S. tax and foreign information reporting laws through strategic enforcement actions directed at identifying U.S. taxpayers involved in abusive offshore tax schemes. In addition, OCI focuses on banks, other financial institutions and third parties that provide, facilitate, or enable offshore financial arrangements and structures. OCI also conducts information gathering and data analysis activities to identify promoters or facilitators of abusive offshore schemes for compliance activities, participates in international forums for improving voluntary compliance, sharing best practices, and leveraging resources, focuses on taxpayers who did not report offshore activity through application of tax treaties and provides technical and procedural guidance on international issues associated with offshore arrangements.

  2. OCI also includes the Joint International Taskforce on Shared Intelligence and Cooperation (JITSIC). JITSIC is a global network of national tax administrations, facilitating, and operationalizing the sharing of intelligence and working together to tackle operational risks in tax administration focusing on abusive transactions.

WEIIC Practice Networks (Inbound and Outbound) Overview

  1. The WEIIC Inbound and Outbound Practice Networks (PN) develop campaigns and provide training and technical support for field teams on individual inbound and outbound transactions as well as transactions involving digital assets.

  2. The WEIIC PN office focuses on compliance issues related to international individual outbound transactions and international individual inbound transactions as well as transactions involving digital assets.

  3. The WEIIC Practice Area includes the following PNs:

    1. Foreign Entities: The Foreign Entities PN considers how U.S. persons with ownership in a foreign entity, such as a controlled foreign corporation, a passive foreign investment company or a foreign pass-thru entity (including foreign partnerships, foreign trusts, and foreign disregarded entities), may need to report their ownership and may also be subject to current U.S. tax on the income earned by that entity.

    2. Foreign Tax Credit: The Foreign Tax Credit PN deals with how a U.S. taxpayer (U.S. citizens, resident aliens, and in very rare cases nonresident aliens) can claim a foreign tax credit on their U.S. individual income tax returns.

    3. Jurisdiction to Tax - Outbound: The Jurisdiction to Tax - Outbound PN considers U.S. taxpayers (U.S. citizens or resident aliens) whose activities generate income that is sourced outside the United States.

    4. Offshore Arrangements: The Offshore Arrangements PN addresses the activities of U.S. individuals (U.S. citizens and resident aliens) using offshore banking, offshore merchant accounts, foreign entities, nominees, other arrangements and schemes, and digital assets to conceal income and ownership of assets to avoid or evade U.S. taxes. This PN also addresses issues related to the reporting of foreign financial assets under Titles 26 and 31.

    5. U.S. Business Activities: The U.S. Business Activities PN considers the business activities of nonresident alien (NRA) individuals. Business activities can include being engaged in a U.S. trade or business (USTB) and the income and expenses effectively connected with a USTB.

    6. Withholding: The Withholding (WIT) PN considers situations where foreign persons engage in U.S. investment activities and the related U.S. withholding tax requirements on income from those investments. The strategic priorities of the WIT PN are to collect the tax before the assets leave the U.S. and apply to two categories of taxpayers: 1) those making payments to others (payers) and 2) those receiving payments from others (payees). The U.S. imposes these withholding taxes as a vehicle to encourage a foreign person’s voluntary compliance.

WEIIC Planning and Special Programs Overview

  1. Planning and Special Programs (PSP) is responsible for the identification, classification, risk assessment, and return delivery of the IIC filing population. It supports the field teams with inventory and workflow by monitoring actual performance against the compliance plan and providing updates and status reports necessary to allocate time and resources properly. PSP responsibilities include:

    • Claims processing

    • Compliance functional automation support

    • Exchange of information screening and examination

    • FinCEN information requests

    • Operation assistance requests (OARs)

    • Competent authority determination/disposition memorandum

    1. Providing compliance oversight of chapter 3 (IRC Sections 1441-1446 and 1461-1464) and chapter 4 (IRC Sections 1471-1474) information reporting and withholding tax matters with an emphasis on servicewide coordination of technical issues, processing, and other information relating to nonresident aliens and foreign corporations.

    3. FATCA operations and compliance, financial intermediary implementation (qualified intermediary, withholding foreign partnership and withholding foreign trusts agreements), and centralized withholding agreements pertaining to nonresident alien athletes and entertainers.

    4. Verifying foreign withholding with respect to credits/claims for refunds on Form 1120-F or Form 1040-NR.

  2. Automatic Exchange of Information (AEOI) is responsible for:

    1. Administering and coordinating all automatic exchanges of information between the U.S. and host country tax authorities (i.e., exchanges occurring on a regular and systematic basis, without the need for specific requests for information).

      Note:

      Automatic exchanges include exchanges of FATCA financial account data, certain information related to the OECD’s base erosion and profit shifting project (country-by-country reporting), and information on U.S.-sourced fixed determinable annual periodic (FDAP) payments to foreign persons and foreign-sourced FDAP payments to U.S. persons (traditional automatic).

    2. Coordinating activities with internal business units and foreign tax authorities with respect to FATCA intergovernmental agreements, confidentiality and data safeguards, and competent authority arrangements relating to AEOI.

    3. Ensuring compliance for foreign financial institutions that fall under FATCA Models 1 and 2 intergovernmental agreements.
