Filling Out IRS Form 56: Complete Line-by-Line Instructions
This article provides a clear, step-by-step guide on understanding, filing, and completing IRS Form 56, the Notice Concerning Fiduciary Relationship.

IRS Form 56, Notice Concerning Fiduciary Relationship, is used to notify the Internal Revenue Service (IRS) when someone acts in a fiduciary capacity on behalf of another person or entity. A fiduciary is someone appointed to manage the affairs of another, such as executors of estates, trustees of trusts, guardians, conservators, or those handling bankruptcy estates or assignments for creditors. The form alerts the IRS to this fiduciary relationship for tax matters, ensuring the fiduciary receives tax notices and information related to the person or entity they represent. This ensures proper handling and accountability of tax obligations and rights for the estate, trust, or individual under fiduciary care. The form is important for various tax types, including income, estate, gift, employment, and excise taxes. Filing this form correctly protects the fiduciary’s authority and helps avoid miscommunication with the IRS.
How to File IRS Form 56?
To file Form 56, the fiduciary completes the form with accurate information about the person or entity they represent and the nature of their fiduciary authority. The completed form should be submitted to the IRS office that handles the tax matters of the person or entity in question. This filing formally notifies the IRS of the fiduciary relationship and the fiduciary’s responsibility regarding tax obligations. Form 56 can be filed at any time after becoming a fiduciary but should be done promptly to ensure proper IRS notifications. If the fiduciary relationship ends or changes, a new Form 56 or a termination notice on the form must be filed as well.
