Hong KongTrusts: revocable, irrevocable, and what each achieves
A revocable trust can be amended or revoked, avoids probate on funded assets, manages incapacity, and provides no estate tax or creditor benefit. An irrevocable trust generally removes assets from the estate at the cost of control.
One question separates them: can the grantor take it back? Everything else follows.
The comparison
| Revocable | Irrevocable | |
|---|---|---|
| Can be amended or revoked | Yes | Generally no |
| Avoids probate on funded assets | Yes | Yes |
| Manages incapacity | Yes | Yes |
| In the grantor's taxable estate | Yes | Generally no |
| Creditor protection for the grantor | No | Generally yes |
| Separate taxpayer | No - grantor trust | Depends on the terms |
| Step-up in basis at death | Yes | Generally no |
The last row is easily missed and matters. Assets in an irrevocable trust outside the estate generally do not receive a step-up, so removing an appreciated asset from the estate can cost more in capital gains than it saves in estate tax - particularly at a USD 15 million exclusion.
What a revocable trust is for
Probate avoidance, privacy, incapacity management, and a single structure for property in several states.
The incapacity point is underrated. The successor trustee steps in without a court process, which a durable power of attorney also does but which institutions sometimes resist.
A revocable trust achieves nothing for assets never retitled into it. Incomplete funding is the most common failure in estate planning, and a pour-over will catches the remainder - through probate, which was the thing being avoided.
Irrevocable trusts
The grantor gives up control, and in exchange the assets are generally outside the taxable estate and beyond the grantor's creditors.
Common uses include an irrevocable life insurance trust holding a policy outside the estate, a trust for minor beneficiaries, a special needs trust preserving benefit eligibility, and asset protection structures.
Grantor trust status
A trust can be irrevocable for estate tax purposes and still treated as owned by the grantor for income tax purposes, if it contains specified powers.
That is deliberate. The grantor pays the income tax on trust earnings, which is itself a tax-free transfer to the beneficiaries - the trust grows undiminished while the grantor's estate shrinks by the tax paid.
The three parties
Grantor creates and funds it. Trustee holds and manages it under a fiduciary duty. Beneficiary receives the benefit.
One person can hold more than one role, and which roles they hold determines the tax and creditor treatment. A grantor who is also trustee with broad discretion has generally not given anything up, which is what questions about failed asset protection describe.
The transfer tax exclusion was changed by the 2025 reconciliation act and is indexed thereafter. Confirm the current figure before relying on it, and check state law separately.
Common questions
What is the difference between a revocable and irrevocable trust?
A revocable trust can be amended or revoked, remains in the taxable estate and offers no creditor protection. An irrevocable trust generally removes assets from the estate at the cost of control.
Does a revocable trust save estate tax?
No. Assets remain in the taxable estate. It avoids probate, provides privacy and manages incapacity, and presenting it as a tax strategy is wrong.
What is the biggest risk with a revocable trust?
Incomplete funding. Assets never retitled into it pass through probate anyway, and a pour-over will catches them - through the process the trust was meant to avoid.
Do irrevocable trust assets get a step-up in basis?
Generally not, if they are outside the taxable estate. Removing an appreciated asset can cost more in capital gains than it saves in estate tax at a high exclusion.
What is a grantor trust?
A trust treated as owned by the grantor for income tax purposes while being irrevocable for estate tax purposes. The grantor paying the income tax is itself a tax-free transfer to beneficiaries.
