How to Set Up an Irrevocable Trust: 7-Step Guide

Setting up an irrevocable trust requires an estate planning attorney, a chosen trustee, and properly funded assets — most families complete the process in 3–8 weeks at a cost of $1,500–$5,000 in attorney fees.

What Is an Irrevocable Trust and Who Should Create One?

An irrevocable trust permanently transfers ownership of your assets to a separate legal entity that you — as the grantor — can no longer control or reclaim, which is precisely why it shields those assets from lawsuits, creditors, and Medicaid recovery.

Unlike a revocable living trust, which you can change or cancel at any time, an irrevocable trust is essentially permanent once signed. That loss of control is not a bug — it is the feature. Because the law no longer considers the trust assets yours, they cannot be seized by your creditors, counted as your personal assets in a Medicaid eligibility review, or included in your taxable estate.

Common reasons to create an irrevocable trust in 2026:

• Medicaid asset protection: Transferring a home into a Medicaid Asset Protection Trust (MAPT) at least five years before applying for nursing-home Medicaid shields it from state recovery. See Medicaid Asset Protection Trust: How a MAPT Works.
• Estate-tax reduction: Assets held in an irrevocable trust are removed from your taxable estate, reducing exposure to the federal estate tax (which kicks in at $13.61 million per individual in 2026).
• Lawsuit and creditor protection: Business owners, physicians, and others with professional liability exposure use Domestic Asset Protection Trusts to shield personal assets from judgments. See Domestic Asset Protection Trust: How It Works.
• Special-needs planning: A special-needs trust funds care for a disabled beneficiary without disqualifying them from Medicaid or SSI.

According to the Internal Revenue Service, an irrevocable trust is one where the grantor has permanently given up all rights to amend, revoke, or reclaim the property — and the trust itself becomes a separate taxpayer responsible for filing its own annual return.

Step-by-Step: How to Set Up an Irrevocable Trust in 2026

The process has seven core steps, and the one most people skip — actually funding the trust — is the one that makes everything else worthless if left undone.

Step 1: Decide which type of irrevocable trust you need

Different trusts serve different goals:

Start with your goal. If your primary concern is nursing-home costs, you need a MAPT. If it is lawsuit protection, look at a DAPT. If it is estate-tax planning for a large life insurance policy, consider an ILIT.

Step 2: Hire a qualified estate planning attorney

Do not use a generic online form service for an irrevocable trust. The legal language must be precisely tailored to your state's statutes, your specific assets, and your goals. A poorly drafted trust may fail to provide its intended protection — or worse, create unintended tax liability.

The American College of Trust and Estate Counsel (ACTEC) advises consumers to seek an attorney who focuses specifically on trusts and estates, ideally one who is board-certified in estate planning by their state bar. Attorney fees for a simple irrevocable trust typically run $1,500–$3,000; complex structures like DAPTs, GRATs, or ILITs can cost $3,000–$7,500 or more.

Step 3: Choose an independent trustee

For most irrevocable trusts, the grantor cannot serve as their own trustee — doing so may collapse the asset protection or disqualify the trust for Medicaid purposes. See Can a Grantor Be Trustee of an Irrevocable Trust? for the specific rules.

Options include a trusted adult family member (low cost but potential conflicts of interest), a professional trust company or bank trust department (ongoing annual fee of 0.5%–2% of assets), or a private professional trustee such as an elder law attorney or CPA.

Step 4: Draft and sign the trust document

Your attorney drafts the formal trust agreement naming the grantor, trustee, successor trustees, and beneficiaries. The document defines:

• Which assets will be placed into the trust
• How distributions are made to beneficiaries
• Who steps in as trustee if the primary trustee cannot serve
• What happens when the trust terminates

You sign the document before a notary. Most states also require two witnesses.

Step 5: Fund the trust — this is not optional

An unfunded trust is a legal document with no practical effect. To transfer assets:

• Real estate: Execute a new deed in the trust's name (e.g., "The [Your Name] Irrevocable Trust dated [Date]") and record it at the county registry of deeds.
• Bank and investment accounts: Retitle existing accounts or open new accounts in the trust's name at your financial institution.
• Brokerage accounts: Complete the trust-accounts paperwork with your broker.
• Personal property: A written bill of sale or assignment document transfers ownership.

Real estate funding typically takes the longest — two to four additional weeks for deed preparation, title company review, and county recording.

Step 6: Obtain an EIN from the IRS

The IRS treats a non-grantor irrevocable trust as a separate taxpaying entity. You must apply for an Employer Identification Number (EIN) — even if the trust holds only a single asset. Applications are free and processed instantly online at irs.gov.

"If you have a trust that qualifies as an irrevocable trust, you'll need to apply for a separate EIN for that trust — it files its own tax return as a separate entity from you." — IRS.gov, Employer Identification Numbers for Trusts guidance.

Step 7: File the trust's annual tax return

Once funded, the trustee must file IRS Form 1041 (U.S. Income Tax Return for Estates and Trusts) every year the trust earns income. Non-grantor irrevocable trusts pay federal income tax at compressed rates — the top 37% bracket starts at just $15,200 in 2026. Many trustees therefore distribute income to beneficiaries annually, who pay tax at their own (often lower) individual rates.

How Much Does It Cost to Set Up an Irrevocable Trust?

The total first-year cost for a simple MAPT protecting a family home typically runs $2,000–$5,000 all-in.

Common Mistakes to Avoid

• Never funding the trust. The most common and fatal error — the trust document alone protects nothing.
• Funding too close to Medicaid. A five-year Medicaid look-back rule applies. Assets transferred within 60 months of applying can trigger a penalty period.
• Choosing the wrong trust type. A standard revocable living trust provides zero asset protection; only an irrevocable trust removes assets from your estate.
• Naming yourself as sole trustee. For Medicaid and creditor-protection trusts, the grantor typically cannot be the trustee. This instantly defeats the purpose.

In Short

Setting up an irrevocable trust means choosing the right trust type for your goal, hiring an estate planning attorney, selecting an independent trustee, having the document drafted and signed, and then transferring your assets into the trust. Get a separate EIN from the IRS and file Form 1041 annually. The process takes 3–8 weeks from first attorney meeting to fully funded trust and costs $1,500–$7,500 depending on complexity. An unfunded trust is worthless — the funding step is not optional.

What You Also May Want To Know

Can I set up an irrevocable trust without a lawyer?

Technically yes using online forms, but it is strongly inadvisable. State-specific legal requirements, funding rules, and tax treatment make DIY irrevocable trusts legally risky. A poorly drafted document may fail to protect your assets and could create unintended tax liability.

What is the difference between a revocable trust and an irrevocable trust?

A revocable living trust can be changed or cancelled by the grantor at any time and provides no protection from creditors or Medicaid. An irrevocable trust permanently transfers asset ownership out of your estate, providing asset protection and potential Medicaid eligibility — but you give up control over those assets.

How long does an irrevocable trust last?

An irrevocable trust lasts as long as needed to fulfill its purpose — typically until all beneficiaries have received their distributions or the last beneficiary dies. The trust document specifies the exact termination conditions. See How to Close an Irrevocable Trust After Death.

Do I need a new EIN every time I add assets to the trust?

No. One EIN per trust, regardless of how many times you add assets later. The EIN stays with the trust for its entire life.

Who pays taxes on income earned inside an irrevocable trust?

In a non-grantor irrevocable trust, the trust itself pays income tax on retained income at compressed trust tax rates. Income that is distributed to beneficiaries is taxed at the beneficiaries' individual rates instead.
