How to Set Up an Irrevocable Trust: Draft, Fund, and File

To set up an irrevocable trust, you gather information on the people and property involved, choose how the trust will be taxed, have an attorney draft the trust instrument, sign it before a notary, transfer assets into it, and get the trust its own tax ID number. Once assets are inside, they leave your taxable estate — the federal estate tax exemption is $15 million per individual in 2026 — and gain protection from most creditors. You also give up control permanently, so every step below matters before you sign.

Gather the Information You Will Need

Drafting starts with three groups of people. The grantor is you, the person providing the assets. The trustee is the person or institution who will manage them. The beneficiaries are the people who will eventually receive distributions. For each beneficiary, record full legal name, date of birth, and Social Security or taxpayer identification number.

Then build an inventory of what you plan to transfer. Real estate needs legal property descriptions and parcel numbers. Financial accounts need institution names and account numbers. Life insurance needs policy numbers and current death benefit amounts. You also need a mailing address where the trust will receive legal notices and tax documents, which is usually the trustee’s address.

Finally, decide how you want distributions to work. You can tie them to specific milestones such as a beneficiary turning 30, finishing college, or buying a first home. Or you can give the trustee broad discretion to distribute funds for health, education, maintenance, and support. Whatever you choose gets written into the document, so working it out now avoids expensive amendments later.

Choose Grantor or Non-Grantor Tax Status

Before drafting, decide who will pay income tax on the trust’s earnings. In a grantor trust, you continue to pay income taxes on everything the trust earns, under the grantor trust rules in Subpart E of Subchapter J of the Internal Revenue Code.¹ Those tax payments further reduce your taxable estate without counting as additional gifts.

In a non-grantor trust, the trust is a separate taxpayer and files its own return. The catch is that trusts hit the top 37% federal bracket at just $16,000 of taxable income in 2026.² An individual does not reach 37% until income is well into six figures. A non-grantor trust holding income-producing assets can face a steep tax bill unless the trustee distributes income to beneficiaries each year. Talk this through with a tax professional before the document is drafted.

Draft the Trust Document

The trust document — sometimes called the trust instrument or trust agreement — is the legal blueprint governing what the trustee can and cannot do. Standardized templates exist, but most irrevocable trusts are complex enough to warrant hiring an estate planning attorney. Fees for a standard irrevocable trust typically run $2,000 to $5,000, depending on asset complexity and the distribution plan.

Certain provisions deserve close attention:

A spendthrift clause prevents beneficiaries from pledging their trust interest as collateral and shields trust assets from a beneficiary’s creditors. Most irrevocable trusts include one.
Successor trustees. Name at least one backup who steps in if the original trustee resigns, becomes incapacitated, or dies. Without this, a court may have to appoint a replacement.
Distribution standards. Clear language on when and how the trustee may distribute funds prevents disputes among beneficiaries.
Crummey withdrawal rights. If you want each contribution to the trust to qualify for the annual gift tax exclusion, the trust should give beneficiaries a temporary right to withdraw newly contributed funds. That right turns a gift of a future interest into a present interest, which is what the annual exclusion requires. The trustee must send written notice to each beneficiary whenever a contribution is made, giving them at least 30 days to exercise the right.³

Both grantor and trustee should read the finished document and confirm it reflects what you actually want. Ambiguous language leads to disputes and unintended tax consequences later.

Sign the Document Properly

A drafted trust becomes legally binding through a formal signing. At minimum, the grantor and the trustee must both sign in the presence of a notary public, who verifies their identities, witnesses the signatures, and attaches an acknowledgment with a seal and commission expiration date. Notary fees are modest, generally capped by state law somewhere between $2 and $25 per signature.

Most states do not require witnesses for a trust signing, unlike the stricter rules for wills. A handful, including Florida, New York, Louisiana, and Delaware, do require one or two witnesses. Even where witnesses aren’t required, having two disinterested adults observe the signing helps defend the document against later claims of undue influence or lack of capacity.

If your state’s signing formalities aren’t followed, a court can declare the trust void. Once properly executed, the document governs every asset that gets transferred in.

Fund the Trust

An executed trust document without assets in it has no practical effect. Funding is the step that actually moves property out of your personal ownership and under the trustee’s control. Each asset type has its own transfer method:

Real estate. Sign and record a new deed, either a warranty deed or a quitclaim deed, with the county recorder’s office. Recording fees vary by location, and some jurisdictions add transfer taxes on top.
Bank and brokerage accounts. Contact the institution and ask to retitle the account in the name of the trust. You will typically need a copy of the trust document or a certificate of trust, plus new signature cards authorizing the trustee.
Life insurance. File a change of beneficiary form with the insurance company designating the trust as beneficiary of the death benefit.
Other personal property. Vehicles, valuable collections, and similar items are transferred through an assignment document attached to the trust.

As you transfer each asset, record it on Schedule A, an attachment to the trust instrument that serves as a running ledger of what the trust owns. Without the actual transfer of title, the trust is an empty shell with no legal control over the property you intended to put in it.

Get an EIN From the IRS

Every irrevocable trust that will earn income or file tax returns needs its own Employer Identification Number, which functions as the trust’s tax ID. Apply online at IRS.gov/EIN and get the number immediately, or submit Form SS-4 by fax (about four business days) or by mail (four to five weeks).⁴ The application asks for the legal name of the trust as it appears on the trust instrument, the trustee’s Social Security number, and the date the trust was created.

The EIN is used to open bank accounts in the trust’s name, file the trust’s annual return (Form 1041), and report income to the IRS. If a return is due before the EIN arrives, write “Applied for” and the application date in the EIN field.⁵ The number stays with the trust for its entire life.

Report the Transfers as Gifts

Transferring assets to an irrevocable trust is treated as a gift under federal tax law because you are permanently giving up ownership. The federal gift tax applies to any transfer of property by gift during a calendar year.⁶ Two exemptions usually keep the actual tax at zero.

The annual exclusion lets you give up to $19,000 per beneficiary in 2026 without triggering gift tax or a filing requirement.² Married couples electing gift-splitting can give up to $38,000 per beneficiary. To qualify when funding an irrevocable trust, you generally need the Crummey withdrawal provision described above, because the annual exclusion applies only to gifts of a present interest.³

The lifetime gift and estate tax exemption shelters up to $15 million in combined gifts and estate transfers for 2026.⁷ Any gift over the annual exclusion reduces this lifetime exemption dollar for dollar, and you owe no actual gift tax unless you use the entire lifetime amount.

Whenever you transfer more than the annual exclusion to the trust in a single year, you must file IRS Form 709 by April 15 of the following year.⁸ The return is required to report the gift and track exemption used, even if no tax is due.

Two Cautions Before You Fund

Retirement Accounts

Naming an irrevocable trust as the beneficiary of an IRA or 401(k) is one of the most common and expensive mistakes in trust planning. When a trust rather than an individual is the designated beneficiary, the favorable distribution rules available to individual beneficiaries generally do not apply.⁹ Depending on the type of trust and circumstances, the balance may need to be fully distributed within five years of the owner’s death. If the trust is a non-grantor trust, that concentrated income gets taxed at the compressed trust brackets. Consult a tax professional before naming any trust as a retirement account beneficiary.

Medicaid Lookback

If part of your reason for setting up the trust is Medicaid planning, timing matters. Federal law allows states to impose a penalty period on anyone who transfers assets for less than fair market value within 60 months before applying for Medicaid nursing home benefits.¹⁰ Transfers into an irrevocable trust fall within this window. An irrevocable trust only works as a Medicaid planning tool if you fund it well before you need long-term care. Transferring assets while you already owe creditors can also expose you to fraudulent transfer claims regardless of Medicaid timing.

What Happens After Setup

Once the trust is running, the trustee has ongoing legal duties. A non-grantor irrevocable trust files Form 1041 every year it earns income; for calendar-year trusts, the return is due April 15.¹¹ Each beneficiary who receives a distribution also gets a Schedule K-1 for their own return.⁵ A grantor trust can use simplified reporting because the income flows onto the grantor’s personal return instead.

The trustee must keep trust assets completely separate from personal funds. Commingling money, even temporarily, is a breach of fiduciary duty. That means a dedicated bank account for the trust and clear records of every transaction. Most states also require the trustee to keep beneficiaries reasonably informed and provide periodic accountings of income received, expenses paid, and distributions made. Failing on these obligations can lead to personal liability and removal by a court.

The name “irrevocable” is not always literal. In states that have adopted the Uniform Trust Code, the trust can be modified if the grantor and all beneficiaries agree, even if the change conflicts with the original purpose. If the grantor is no longer living, beneficiaries can petition a court for modification, though the court will generally only approve changes consistent with the trust’s material purposes. Modification exists as a safety valve, but it requires either unanimous consent or judicial involvement, so don’t count on it as a routine option.
