A trust in estate planning is a legal arrangement in which you transfer property to a person or institution to hold and manage for someone else’s benefit, following written rules you set when you create it. By moving assets into a trust, you build a structure that governs how your property is invested, maintained, and eventually distributed, usually without a court getting involved. It is one of the most flexible tools in estate planning, used to skip probate, keep an estate private, plan for incapacity, cut estate taxes, and shield assets from creditors.
A will tells a probate judge what you want to happen after you die. A trust acts on its own, through the trustee you chose, under the instructions you already wrote down.
The Three Roles Inside Every Trust
A trust always involves three roles, though one person can fill more than one of them.
The grantor (also called the settlor or trustor) is the person who creates the trust, puts property into it, picks the beneficiaries, and sets the rules the trustee has to follow.
The trustee is the person or institution that actually manages the property. A trustee owes a fiduciary duty to the beneficiaries, which means acting with care, loyalty, and good faith. They cannot use trust assets for themselves or favor one beneficiary over another unless the trust document specifically allows it. Beneficiaries who believe a trustee has broken those duties can go to court to have the trustee removed or held personally liable for losses.
The beneficiary is whoever receives the benefit of the trust property. Depending on what the trust says, that benefit might be regular income, a lump sum at a certain age, or payments limited to specific purposes like tuition or medical care. A single trust can name multiple beneficiaries and stagger what they get over decades.
Revocable or Irrevocable: The First Choice
Nearly every trust in estate planning falls into one of two camps, and the difference drives almost everything else.
Revocable Trusts
A revocable trust, often called a living trust, is one you can change or cancel at any time while you’re alive. You usually serve as your own trustee, so you keep full control. You can add property, remove it, swap beneficiaries, or dissolve the whole arrangement whenever you want.
Because you keep that control, the IRS treats the assets as still yours. You report the income on your personal return, and the property counts as part of your taxable estate.1Federal Long Term Care Insurance Program.

When you die, a revocable trust automatically becomes irrevocable, and the successor trustee you named takes over to manage and distribute what’s inside according to your written instructions.1Federal Long Term Care Insurance Program. Types of Trusts for Your Estate – Which Is Best for You
Irrevocable Trusts
An irrevocable trust is one you cannot change or cancel after it is created and funded. You give up ownership of whatever you put in. The trust becomes the permanent legal owner. That loss of control is the whole trade-off, and it buys you two things a revocable trust cannot.
First, estate tax savings. Because you no longer own the assets, they are not counted in your taxable estate when you die. For 2026, the federal estate tax basic exclusion is $15 million per person, and estates above that face a rate of up to 40 percent on the excess.2Internal Revenue Service. What’s New – Estate and Gift Tax3Office of the Law Revision Counsel. 26 USC 2010 – Unified Credit Against Estate Tax If your estate could clear that threshold, moving assets into an irrevocable trust during your lifetime can meaningfully shrink what your heirs owe.
Second, stronger creditor protection. Since the assets are no longer yours, your personal creditors generally cannot touch them. Many irrevocable trusts also include a spendthrift clause, which blocks a beneficiary’s own creditors from reaching distributions before the beneficiary gets them, and prevents the beneficiary from pledging their interest as collateral. Most states carve out an exception for child support and alimony, which can be enforced against trust distributions even when a spendthrift clause exists.
Modifying an irrevocable trust is hard but not always impossible. In many states, the grantor and all beneficiaries can agree to change or end it, and a court can order changes when the original purpose has been fulfilled or circumstances have shifted in ways the grantor could not have anticipated. Those are exceptions. The default rule is that the terms are permanent.
What a Trust Actually Does for Your Estate
The reason trusts show up in so many estate plans is that a well-drafted one solves several problems at once.
Avoiding probate. Assets held in a trust pass directly to your beneficiaries when you die. There is no court-supervised probate, which can run months or even years.
Privacy. A will becomes a public court record once it is filed for probate. A trust does not. The details of what you owned and who inherits stay private.
Planning for incapacity. If you become unable to manage your own affairs, the successor trustee named in your trust document steps in right away to handle the finances inside the trust. Without that, your family would likely have to go to court to get a guardian or conservator appointed, which is slow and expensive.
Estate tax reduction. Only an irrevocable trust pulls assets out of your taxable estate. A revocable trust does not, because you kept the power to take the property back.4Office of the Law Revision Counsel. 26 USC 2038 – Revocable Transfers
Step-up in basis. Assets in a revocable trust get a basis reset to fair market value on the date of your death, so beneficiaries who sell shortly afterward owe little or no capital gains tax.5Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent Assets in an irrevocable trust may not get that step-up, depending on how the trust is structured. The trade-off between estate tax savings and capital gains treatment is one of the biggest reasons to talk through options before picking a trust type.
Creditor protection for beneficiaries. A spendthrift clause inside an irrevocable trust can keep a beneficiary’s inheritance out of reach of their creditors.
How a Trust Is Taxed
Trust tax treatment turns on whether the trust is a “grantor trust” or a separate taxable entity.
A revocable trust is the most common grantor trust. The IRS looks past it during your lifetime because you can still take the assets back. You report any income on your own return, and the trust does not need its own tax ID. Once you die, the trust becomes a separate entity and must get its own Employer Identification Number.6Internal Revenue Service. When to Get a New EIN Some irrevocable trusts also count as grantor trusts if the grantor keeps certain powers listed in the tax code, such as the power to swap trust assets for assets of equal value. In those cases, the grantor keeps paying the income tax even though the trust itself cannot be revoked.
An irrevocable trust where the grantor has given up all control is a separate taxpayer. It needs its own EIN and must file IRS Form 1041 if it earns $600 or more in gross income during the year, or has any taxable income at all.7Internal Revenue Service. Instructions for Form 1041
One thing worth knowing before you set one up: trust tax brackets are tightly compressed compared to individual brackets. A trust hits the top federal rate of 37 percent on income above just $16,000 in 2026, while a single filer does not reach that bracket until taxable income is well into six figures.8Internal Revenue Service. 2026 Form 1041-ES That is why many irrevocable trusts distribute income out to beneficiaries, who then report it on their own returns at their lower rates; the trust gets a deduction for what it distributes.
Creating and Funding a Trust
Setting up a trust means drafting a trust agreement, the legal document that names the grantor, trustee, successor trustee, and beneficiaries, and lays out the rules for managing and distributing assets. Attorney fees for a trust-based estate plan generally run $2,000 to $5,000, with simpler plans costing less and plans involving multiple trusts, blended families, or business interests costing more.
The document itself needs full legal names and detailed descriptions of the property going in. For real estate, that means the legal description from the deed. Name a successor trustee too, so someone is ready to step in if the primary trustee dies, resigns, or becomes incapacitated.
Drafting is only half the work. A trust only controls property that has actually been transferred into it, a step called funding. An unfunded trust is an empty container, and anything left outside will likely go through probate anyway. How you fund depends on the asset:
- Real estate: Sign a new deed moving the property from your name into the trust’s name, and record it with the county recorder’s office.
- Bank and investment accounts: Ask the institution to retitle the account in the trust’s name. Most will want a certificate of trust or a copy of the trust agreement to confirm the trustee’s authority.
- Life insurance and retirement accounts: These pass by beneficiary designation, not by title. You can name the trust as beneficiary, but doing so with an IRA or 401(k) can create tax complications, so talk to a tax advisor first.
A pour-over will acts as a safety net. It directs that anything still in your individual name at death gets “poured over” into the trust. Those assets still have to go through probate before they land in the trust, so the goal is to fund the trust as fully as you can while you are alive.
Who Runs the Trust After You’re Gone
When the grantor dies or becomes incapacitated, the successor trustee takes over. They establish authority by presenting a certified copy of the trust agreement, or a shorter certification of trust, along with any required death certificates, to the banks and brokerages holding trust assets.
From there, the trustee has to:
- Inventory and value every asset the trust holds.
- Notify beneficiaries that the trust exists, that administration has begun, and what the trust says about their interests. Most states require this.
- Invest trust assets prudently, balancing current income against long-term growth.
- Make distributions on the schedule and conditions the trust document sets.
- File Form 1041 each year once the trust is irrevocable, if gross income reaches $600.7Internal Revenue Service. Instructions for Form 1041
- Keep detailed records of income, expenses, distributions, and investment decisions.
Professional trustees, usually banks or trust companies, charge annual fees of roughly 0.5 to 1.5 percent of trust value, with larger trusts paying the lower end of that range. Family members or friends serving as trustee often take no fee, though the trust document can authorize a reasonable one.
