A trust is not a single type of entity with one clean answer. Under traditional common law, a trust is a fiduciary relationship, not a separate legal entity: one person (the trustee) holds and manages property for the benefit of another (the beneficiary), and the trust itself has no independent legal existence. Tax law changes that picture for some trusts, treating them as standalone taxpayers. And a handful of states have created statutory trusts that genuinely are legal persons, able to own property and sign contracts in their own name. So the honest answer to what type of entity a trust is depends on which trust and which body of law is asking.
The Common-Law Answer: A Trust Is a Relationship
Start with the traditional rule, because it still governs the vast majority of family and estate-planning trusts. A corporation can sign contracts, own property in its own name, and be sued. A common-law trust cannot do any of those things directly. The trustee does everything on behalf of the trust. When someone needs to sue over trust property, they sue the trustee in a representative capacity, not the trust.
A trust has no birth certificate from the state and no articles of organization filed with a secretary of state. It springs into existence when a person transfers property to a trustee under terms that create enforceable duties. The relationship is governed by the trust document, the applicable state’s trust code, and centuries of case law. The trust is a web of duties, not a standalone participant in the legal system.
Split Ownership Is What Makes It Work
The structural feature that defines a trust is split ownership. The trustee holds legal title to the trust property, which gives the trustee the authority to manage, invest, and make decisions about those assets. The beneficiary holds equitable title, which is the right to benefit from the property. This split is the whole point: the person with decision-making power is legally bound to act in the interest of someone else, and courts enforce that obligation.
Because the trustee holds legal title, the fiduciary duties attached to that position are the primary mechanism protecting the beneficiary. The duty of loyalty, duty of care, duty of impartiality among beneficiaries, and duty to inform and account are enforceable in court, and a trustee who breaches them can be held personally liable. That is the practical face of “a trust is a relationship.” The protection runs through the trustee’s obligations rather than through any separate corporate shell.
The Parts of a Trust
Every trust involves at least three roles and a pool of property.
- Grantor (also called the settlor or trustor): the person who creates the trust and transfers property into it. In many revocable trusts, the grantor also serves as the initial trustee.
- Trustee: the person or institution responsible for managing the trust property according to the trust document’s instructions. A trustee can be an individual, a group of co-trustees, or a corporate trustee such as a bank or trust company.
- Beneficiary: the person or group entitled to receive distributions or income from the trust. A trust can have current beneficiaries receiving income now and remainder beneficiaries who receive assets when the trust ends.
- Trust property (also called the trust res or corpus): the actual assets held in the trust. Without property, there is no functioning trust. The property can include cash, real estate, investment accounts, business interests, or nearly anything else of value.
Some modern trusts also name a trust protector, a person given specific powers the trustee does not hold, such as the ability to modify administrative provisions, change the trust’s governing state, or remove and replace the trustee. Trust protectors are especially useful in long-term trusts where circumstances will change over decades.
How Tax Law Classifies a Trust
The IRS does not care about the common-law “it’s a relationship” framing. For federal income tax purposes, every trust is sorted into one of two categories, and the sorting changes whether the trust is treated as its own entity or ignored.
Grantor Trusts: Ignored as a Separate Entity
If the grantor keeps certain powers over the trust, such as the power to revoke it, the IRS disregards the trust as a separate tax entity.1Office of the Law Revision Counsel. 26 US Code 676 – Power to Revoke All income, deductions, and credits flow through to the grantor’s personal Form 1040. The trust files nothing of its own. This applies to every revocable trust by definition and to some irrevocable trusts where the grantor retains specific economic interests or powers described in IRC sections 671 through 679.2Internal Revenue Service.

Because the grantor never truly gives up control of a revocable trust, the law treats it as an extension of the grantor’s personal financial identity. Creditors pursuing the grantor can generally reach revocable trust assets as if the grantor still owned them outright. The trust does not need its own tax identification number during the grantor’s lifetime.
Non-Grantor Trusts: A Separate Taxpayer
When the grantor retains none of the triggering powers, the trust becomes its own taxpayer. It must obtain an Employer Identification Number and file Form 1041 annually if it has any taxable income or gross income of $600 or more.3Internal Revenue Service. 2025 Instructions for Form 1041 and Schedules A, B, G, J, and K-1 The tax code imposes income tax on trust income under the same rate structure as individuals, but the brackets are severely compressed, so trusts hit the top rate at a far lower income level than individuals do.4Office of the Law Revision Counsel. 26 US Code 641 – Imposition of Tax
A revocable trust typically crosses this line when the grantor dies. At that point the trust becomes irrevocable, obtains its own EIN, begins filing its own returns, and operates as a separate entity for tax and legal purposes.
Revocable vs. Irrevocable: How Much Separation Exists
The common-law question of whether a trust is a meaningful separate thing tracks closely with whether it is revocable or irrevocable.
A revocable trust is one the grantor can amend, rewrite, or dissolve at any time. The lack of real separation is why creditors can reach the assets and why the IRS treats the trust as part of the grantor. The appeal of a revocable trust is not creditor protection or tax savings; it is probate avoidance. When the grantor dies, properly funded revocable trust assets pass to beneficiaries outside probate.
An irrevocable trust creates a hard boundary. Once property goes in, the grantor typically cannot reclaim it or change the trust’s terms. That loss of control is the point: because the grantor no longer owns or controls the assets, the trust stands on its own. Assets are generally excluded from the grantor’s taxable estate. Creditors pursuing the grantor typically cannot reach them. And if the trust includes a spendthrift clause, even the beneficiary’s own creditors are blocked from seizing trust assets before the trustee makes a distribution. Most states recognize valid spendthrift provisions, though the exact scope of protection varies.
In both cases, though, the trust is still a common-law trust. The separation is a matter of degree and of tax treatment, not of entity status. Neither type is filed with a secretary of state. Neither has independent legal personhood under state law.
Statutory Trusts: When a Trust Really Is a Legal Person
Several states have created a different animal: the statutory trust. A statutory trust is formed by filing a certificate of trust with a secretary of state, and the resulting entity is treated as a separate legal person by statute. It can own property, enter contracts, and sue or be sued in its own name, much like a corporation or LLC.
Delaware’s statutory trust framework is the most widely used, particularly in structured finance and commercial real estate. Delaware statutory trusts serve as the underlying vehicle for many real estate investment trusts and asset securitization transactions. They offer advantages over common-law trusts in commercial settings, including a clear statutory framework governing internal affairs, the ability to appear as a party to contracts in its own name, and features that limit the risk of the entity being pulled into bankruptcy proceedings.
Formation costs vary by state but typically run between $35 and $125 in state filing fees, comparable to forming an LLC. Because statutory trusts are created by filing with a state office, the question of federal beneficial ownership reporting has come up. Under the Corporate Transparency Act, a domestic entity created by filing a document with a secretary of state would normally qualify as a reporting company required to file beneficial ownership information with FinCEN. However, an interim final rule published in March 2025 exempted all entities formed in the United States from this requirement.5FinCEN.gov. Beneficial Ownership Information Reporting As of 2026, only foreign entities registered to do business in the U.S. must file beneficial ownership reports.6FinCEN.gov. Frequently Asked Questions
The statutory trust matters because it represents a genuine departure from the traditional answer. For common-law trusts, the answer is that a trust is a relationship. For statutory trusts, the answer is that a trust is a legal person. Both carry the same name and operate under fundamentally different frameworks.
What the Classification Actually Changes
The entity question is not academic. It drives several practical consequences.
- Lawsuits over trust property are brought by or against the trustee in a representative capacity, not against a common-law trust directly. A statutory trust can be named as a party in its own right.
- Property is titled in the name of the trustee “as trustee of” the trust for common-law trusts. A statutory trust can hold title in its own name.
- Revocable trusts use the grantor’s Social Security number during the grantor’s lifetime; irrevocable non-grantor trusts and statutory trusts need their own EIN.
- Creditor exposure follows the degree of separation. A revocable trust gives essentially none; an irrevocable trust generally does; a statutory trust’s exposure depends on the structure of the deal and the governing statute.
So when you need to answer what type of entity a trust is, the useful move is to ask which trust. A revocable living trust is a legal relationship that the IRS ignores and that creditors see through. An irrevocable common-law trust is a legal relationship that functions as a separate taxpayer and a meaningful shield. A statutory trust is a filed entity with its own legal personhood. All three answer to the word “trust,” and the differences between them are larger than the word suggests.
