§6105 Confidentiality of Information Arising Under Treaty Obligations

Title 26 › Subtitle Subtitle F— Procedure and Administration › Chapter 61— INFORMATION AND RETURNS › Subchapter B— Miscellaneous Provisions › § 6105

Summary

Information that the United States shares with other countries under tax treaties must be kept secret. That covers agreements made with foreign tax authorities, applications for treaty relief, background materials, documents that carry out those agreements, and any other information a treaty treats as confidential. A "tax convention" means an income, gift, or estate tax treaty, or any other agreement with a foreign country or U.S. possession on avoiding double taxation, stopping tax evasion, or sharing tax information. There are limited exceptions. The information can go to courts, agencies, or others the treaty itself allows, and certain disclosures permitted under section 6103(i) can be made — though if the information came from a foreign government, that government must give written consent first. Information not tied to a specific taxpayer can be released if the Secretary, after consulting the treaty partners, decides it would not harm tax administration. Leaking this information without permission can bring penalties under other sections of the tax code.
