Client Checklist & Process Documentation
Document Version: 1.0 | Effective Date: January 2026 | Classification: Client Use
WHAT IS THE TRIPLE LOCK?
The Triple Lock is a comprehensive IRS notification protocol that establishes and documents fiduciary relationships for trusts, estates, and business entities. It consists of three coordinated IRS filings that work together to:
- Designate the Responsible Party with the IRS
- Establish Fiduciary Authority for tax matters
- Create Official Record of the trust/entity relationship
The Three Components
| Form | Purpose | Function |
| Form 8822-B | Change of Responsible Party | Designates who receives IRS correspondence and is accountable for the entity |
| Form 56 | Notice Concerning Fiduciary Relationship | Establishes fiduciary authority to act on behalf of the entity with the IRS |
| Form 56-F | Notice Concerning Fiduciary Relationship (Financial Institution) | Specialized notice for entities with financial/banking functions |
WHY IS THE TRIPLE LOCK IMPORTANT?
Benefits of Completion
- IRS Communication Control: All correspondence directed to designated party
- Fiduciary Authority: Legal standing to act on entity's behalf with IRS
- Audit Protection: Clear documentation of who is authorized to respond
- Compliance Foundation: Required foundation for ongoing tax compliance
- Asset Protection: Proper structural documentation supports entity separation
Risks of Non-Completion
- IRS notices sent to wrong address or person
- Missed deadlines due to misdirected correspondence
- Lack of authority to resolve tax matters
- Penalties for failure to respond to IRS inquiries
