Two grandfathers each create a trust with 9 million but paid 9 million because the grandfather structured it as a grantor trust and paid the taxes himself. Same goal. Same assets. Structure determined everything.
HIGH-FREQUENCY: The three-axis classification system (revocable/irrevocable, grantor/non-grantor, simple/complex) is the foundation of nearly every trust question. Classify first, then analyze.
A revocable trust can be amended or terminated by the grantor at any time. Because the grantor retains control, the trust is ignored for tax purposes during life. All income is reported on the grantor's return. All assets are included in the gross estate under Section 2038.
A revocable trust provides no income tax savings and no estate tax savings. Its benefits are purely non-tax: probate avoidance, privacy, incapacity management through the successor trustee, and elimination of ancillary probate.
An irrevocable trust cannot be changed once established. The grantor has permanently parted with the assets. The transfer is a completed gift.
Common mistakes
- Revocable trust as tax shelter. Candidates attribute estate tax savings to revocable trusts. A revocable trust provides zero estate tax benefit. Assets are fully included in the grantor's estate.
- TRAP: "The revocable trust shelters assets from estate tax", the opposite is true. Only irrevocable trusts remove assets.
- Grantor trust = estate inclusion. A trust can be an irrevocable grantor trust, excluded from the estate but income-taxed to the grantor. Grantor trust status and estate inclusion are governed by different code sections.
Bottom line
- Revocable trusts avoid probate and manage incapacity but provide zero estate tax benefit; assets are fully included in the gross estate.
- Irrevocable trusts remove assets from the estate but require surrendering control, making the transfer a completed gift.
- Grantor trust status (income tax) and estate inclusion (estate tax) are independent; an IDGT is irrevocable for estate tax but grantor for income tax.
- Non-grantor trusts hit the 37% bracket at roughly $16,000 of income; distribute to lower-bracket beneficiaries.
Exam shortcut
Classify every trust along three axes before answering: revocable or irrevocable (estate inclusion), grantor or non-grantor (income tax), simple or complex (distribution). For married couples, evaluate QTIP (marital deduction + remainder control), bypass (exemption + appreciation shelter), or both. The strongest plans for large estates use both trusts together.
