The primary difference between these two lies in their creation and the extent of control exert by the settlor (the person who creates the trust). Let's delve into each, their subcategories, and the distinct features that set them apart.

Trust Under Agreement

A trust under agreement, also known as an express trust, is a voluntarily created trust where the settlor states the terms of the trust in an agreement. This could be a standalone document or incorporated into a will.

The unique feature here is that the trust's existence and terms primarily depend on an agreement or contract, providing flexibility in customization. However, it loses effectiveness if the agreement is deemed invalid or unenforceable.

Irrevocable Trusts

Irrevocable trusts are a type of trust under agreement where the settlor relinquishes all control over the trust assets after its creation. This type is particularly appealing for estate tax reduction strategies, as assets are effectively removed from the settlor's taxable estate.

Assets are safeguarded from the settlor's creditors, providing further asset protection. However, the settlor cannot access or modify the trust once it's established.

Revocable Trusts

Revocable trusts, another type under agreement, allow the settlor to retain control over the trust assets. This means the settlor can modify or terminate the trust at any time, providing flexibility during their lifetime.

Revocable trusts can help avoid probate, as assets transfer directly to beneficiaries upon the settlor's death. However, the assets remain part of the settlor's taxable estate until their passing.

A grantor trust is a trust where the grantor (the creator of the trust) is considered the owner of the trust assets for income tax purposes. This is irrespective of whether the grantor has control over the assets or not.

In a grantor trust, the grantor is responsible for filing the trust's tax returns and reporting the income on their personal tax return. This distributes income tax liability, often leading to significant tax savings.

Intentionally Defective Grantor Trusts (IDGT)

IDGTs are a type of grantor trust designed to remove assets from the grantor's taxable estate while allowing the grantor to indirectly benefit from the trust's growth. This is achieved through the strategy of paying gift taxes for the beneficiaries.

IDGTs can be useful for estate planning, as they help lower the taxable value of the estate through gifting strategies. However, their complexity requires careful consideration and guidance from a professional.

Irrevocable Life Insurance Trusts (ILIT)

ILITs are another type of grantor trust that owns life insurance policies. Upon the insured's (usually the grantor) death, the trust collects the death benefit, which is then distributed to the beneficiaries according to the trust's terms.

The primary advantage of an ILIT is that it keeps the life insurance proceeds out of the taxable estate, reducing potential estate tax liability. It also provides asset protection and offers flexibility in how the death benefit is distributed.

Understanding the nuances of trust under agreement and grantor trusts allows for informed decision-making when it comes to wealth management, estate planning, and tax strategies. It's crucial to consult with a trusted financial advisor or estate planning attorney to explore the options that best suit your unique needs and circumstances. This way, you can create a solid foundation for protecting your assets and facilitating a smooth transition to your beneficiaries.
