What is a Trust in Estate Planning?

A trust is a legal arrangement in which one party, the trustee, holds and manages assets on behalf of another, the beneficiary, according to terms set by the person who created it. Trusts are a core estate planning tool because they let you control how and when assets pass to others, often while avoiding probate.

The money and property held inside a trust are often called a trust fund, a phrase that in everyday use usually means assets set aside for a child or other family member.

How Does a Trust Work?

A trust has three roles. The grantor (also called the settlor) creates the trust and funds it. The trustee manages the assets and is bound by fiduciary duty to follow the trust’s terms. The beneficiary receives the benefit, whether that is income, principal, or both. One person can occupy more than one role, which is why a revocable living trust typically names its creator as both grantor and trustee during their lifetime, with a successor trustee who takes over at incapacity or death.

The trust document sets the rules: who receives what, when, and under what conditions. It only controls assets actually titled in the trust’s name.

Revocable vs. Irrevocable Trusts

A trust is either revocable or irrevocable, depending on whether it can be changed after it is created.

A revocable trust can be amended or dissolved by the grantor at any time. Because the grantor retains control, the assets are still considered theirs for tax and creditor purposes. Revocable trusts avoid probate and provide privacy, but they do not reduce estate taxes or shield assets from creditors.

An irrevocable trust generally cannot be modified once established without beneficiary consent or court approval. Giving up that control is the point: a properly structured irrevocable trust can remove assets from the grantor’s taxable estate and may protect them from creditors, though both depend on which powers and benefits the grantor keeps. The tradeoff is permanence, and there are tax costs too: the transfer is generally a taxable gift, and amounts not covered by the annual gift tax exclusion (which applies to a gift in trust only when beneficiaries have a present right to it) use up part of your lifetime estate and gift tax exclusion. Assets outside your estate generally don’t receive a step-up in basis at death.

Types of Trusts

Living trusts are created during the grantor’s lifetime, as opposed to testamentary trusts, which are established by a will and only take effect at death. A testamentary trust does not avoid probate, since the will itself must be probated first. Beyond that basic split, most trusts are named for the job they do.

A spendthrift clause does not by itself limit how much a beneficiary receives; the distribution terms do that. Once money is paid out, it is generally reachable by the beneficiary’s creditors.

Trusts are also classified as grantor or non-grantor trusts, which is a tax distinction rather than a type of arrangement. It determines who pays income tax on what the trust earns, covered below.

Benefits of a Trust

The first benefit is probate avoidance. Assets held in a trust pass directly to beneficiaries under its terms rather than going through the court process, which saves time and keeps the distribution private. Probate is a public proceeding; a trust is not.

The second is control over timing and conditions. A will usually distributes assets outright. A trust can hold them and release them on a schedule, at certain ages, or subject to conditions, which is why trusts are common where beneficiaries are young or where the grantor wants to protect an inheritance from being spent quickly.

Estate tax reduction applies to a narrower group. For 2026, the federal estate tax basic exclusion amount is $15,000,000 per person, and a married couple can combine their exclusions if the estate of the first spouse to die elects portability on a Form 706 filed after the first death (estates not otherwise required to file have up to five years). Below that threshold, a trust is about probate, privacy, and control rather than federal estate tax. Some states levy their own estate or inheritance taxes at much lower thresholds (Oregon requires an estate tax return at $1 million, Massachusetts above $2 million), so the calculation depends on where you live. Because both federal and state thresholds change, confirm current figures when planning.

How Are Trusts Taxed?

Income tax depends on whether the trust is a grantor or non-grantor trust.

A grantor trust is ignored for income tax purposes. Every revocable trust is a grantor trust, and some irrevocable trusts are deliberately drafted as grantor trusts too. The grantor reports the trust’s income on their own return and pays tax at their own rates, as if the trust did not exist.

A non-grantor trust, which includes many irrevocable trusts and any trust that continues after the grantor’s death, is a separate taxpayer. It files its own return, Form 1041, and pays tax on income it keeps. Trust brackets are compressed: for 2026, the 37% rate applies to retained trust income above $16,000, compared with $640,600 for a single filer.

Income the trust distributes is generally taxed to the beneficiaries instead. Distributions carry out the trust’s distributable net income (DNI), roughly its taxable income for the year, so a beneficiary is taxed on what they receive up to their share of DNI and the trust deducts the same amount. The trust reports each share on a Schedule K-1, and beneficiaries pay at their own rates. Amounts paid out beyond the year’s DNI, such as a return of contributed principal, generally aren’t taxable to the beneficiary. That is why many trusts distribute income rather than accumulate it, though the trust terms, not taxes alone, decide what can be paid out.

How to Set Up a Trust

A trust that is never funded does nothing, so after signing the trust document you also have to retitle accounts and property into the trust’s name. Assets left outside it still go through probate.

The other decisions that matter are choosing a trustee who will actually be able to serve, drafting terms specific enough to be administrable, and coordinating the trust with the rest of your estate plan so a will and beneficiary designations do not contradict it. Beneficiary designations on retirement accounts and life insurance override what a will or trust says.

You can draft a trust with an estate planning attorney or with online document software. Online templates cost less and can handle a simple revocable living trust, but they won’t flag state-specific issues, coordinate the trust with your other documents, or help you fund it correctly. An attorney costs more and is generally the safer choice for irrevocable trusts, special needs trusts, blended families, property in several states, or estates near the tax thresholds, where drafting details carry real consequences.

Frequently Asked Questions

What is the difference between a trust and a will? A will directs how assets are distributed after death and must go through probate. A trust holds assets during your lifetime and after, passes them outside probate, and can control the timing of distributions. Many estate plans use both.

Do I need a trust if I already have a will? Not necessarily. A trust is most useful if you want to avoid probate, own property in multiple states, want privacy, or need to control distributions over time. A straightforward estate with named beneficiaries on the major accounts may be adequately served by a will.

Does a trust avoid estate taxes? A revocable trust does not. Certain irrevocable trusts can remove assets from your taxable estate, but for estates below the $15,000,000 per-person federal exclusion for 2026, giving up the step-up in basis can raise taxes for your heirs.

Who should be the trustee? Someone capable of administering assets impartially and willing to take on the responsibility. You can serve as trustee of your own revocable living trust and name a successor. Corporate trustees are an option where the assets are complex or family dynamics are difficult.
