This webinar will provide trust tax advisers with a comprehensive and practical guide to the tax calculations, benefits and potential hazards involved with making a Section 645 election to treat qualified revocable trusts (QRTs) as estates. The panel will detail the impact of the “separate share rule” of IRC 663 in calculating DNI, making tax allocations, and reporting the separate shares impact on the Form 1041.


A powerful but misunderstood post-mortem planning tool for estate advisers is the IRC Section 645 Election to Treat a Qualified Revocable Trust as Part of an Estate. While this election can provide significant flexibility in minimizing income tax, advisers must be aware of the potential tax consequences of failing to properly allocate income and distributions between the estate and its component trust.

The election provides tax advisers to qualified revocable trusts with several key advantages. The ability to treat a QRT as an estate allows advisers and fiduciaries to select a fiscal year, rather than defaulting to a calendar year as required under trust reporting. This provides fiduciaries with greater flexibility in timing income and distributions. The election also waives the material participation requirement for purposes of the passive loss rules.

While making a 645 election allows the fiduciary to file a single Form 1041 Income Tax Return, the tax adviser must treat the estate and the component QRT as separate shares for purposes of calculating distributable net income (DNI).

Fiduciaries and compliance professionals must be aware of the application of the separate share rule to trusts making a Section 645 election to ensure income and distributions are properly allocated and avoid unnecessary entity-level income tax.

Listen as our experienced panel provides a comprehensive and practical guide to using a Section 645 election to reduce income tax on qualified revocable trusts.
