Summary

Tax convention information must not be shared with others. But it can be shared in four cases: to people or courts allowed to see it under the treaty; as part of normal rules for asking for treaty relief; under the same rules that apply to tax return information (but if a foreign government gave the information, you must have its written consent); or when the Secretary, after talking with the other treaty party, agrees non-identifying information can be released. “Tax convention information” means agreements with foreign tax authorities, requests for treaty relief, background papers, documents that put an agreement into effect, and other exchanged items marked confidential. “Tax convention” means tax treaties or other pacts to avoid double taxation, prevent tax evasion, share tax information, or help with tax matters. Penalties for improper release of return-related treaty information are in sections 7213, 7213A, and 7431.
