Setting up a business trust means creating a legal arrangement in which a trustee holds and manages your business assets for named beneficiaries under the terms of a written trust agreement. To set it up, you choose between a revocable and an irrevocable structure, work with an attorney to draft and execute the trust agreement, obtain an Employer Identification Number if the trust needs one, and then retitle each business asset into the trust’s name. The choices you make at the structure stage decide how much control you keep, whether the assets are shielded from creditors, and how the IRS taxes what the trust earns.
Pick the Structure First: Revocable or Irrevocable
Every other decision follows from this one.
A revocable trust keeps you in charge. You can change the terms, swap beneficiaries, add or remove assets, or dissolve the trust entirely. Because you still control the assets, creditors can reach them as if you owned them outright, and the trust is not a separate taxpayer during your lifetime. Income flows onto your personal return under your Social Security number. What you get in exchange is succession planning: when you die or become incapacitated, your successor trustee keeps the business running without probate.
An irrevocable trust is much harder to unwind. Once assets go in, you generally cannot take them back or rewrite the terms on your own. In return, the assets legally belong to the trust rather than to you, so your personal creditors typically cannot reach them, and the transferred value comes out of your taxable estate. The trust becomes its own taxpayer, and trust tax brackets are steep. Some modern irrevocable trusts include a trust protector who can make limited changes, but permanence is the default.
If day-to-day liability protection is your only goal, a limited liability company is usually the cleaner tool. Trusts earn their keep when the priority is succession planning, controlled distributions to family beneficiaries, or centralized management of multiple business and investment holdings.
Decisions to Lock Down Before Drafting
Your attorney can only draft what you have decided. Before the first meeting, work through these:
- Purpose. Asset protection, succession, and charitable goals each pull the trust terms in different directions.
- Assets. List exactly what goes in: real estate, bank accounts, equipment, intellectual property, ownership interests in other entities. Vague descriptions cause problems at the funding stage.
- Trustee. Yourself (common with revocable trusts), another individual, or a corporate trustee such as a bank or trust company. Corporate trustees offer continuity but charge annual fees, often a percentage of trust assets.
- Successor trustee. Whoever takes over if the original trustee dies, resigns, or cannot serve. This is the person who keeps the business running through a transition.
- Beneficiaries. Family members, business partners, charitable organizations, or some combination.
- Distribution terms. Regular income, trustee’s discretion, or milestones such as a beneficiary reaching a certain age.
Changing these later is easy with a revocable trust and difficult or impossible with an irrevocable one. Also pull together your personal identification, property deeds, business registration documents, existing EIN, financial account statements, and any insurance policies on assets being transferred. Having the paperwork ready shortens the drafting cycle.
Drafting and Signing the Trust Agreement
The trust agreement is the operating manual. It should identify the grantor, trustee, and beneficiaries; describe the assets; set out the trustee’s powers and limits; specify distribution rules; name successor trustees; and state when the trust terminates. For a business trust, pay particular attention to how the trustee can operate the business, whether the trustee can hire employees or sign contracts, and what happens if the business needs to borrow.1Bank of America Private Bank. Understanding Your Trust
This is not a do-it-yourself document. An experienced trusts-and-estates attorney will translate your decisions into enforceable provisions, plan for scenarios you have not thought about (a beneficiary’s divorce, a trustee’s bankruptcy), and make the agreement fit your state’s trust laws. Expect legal fees running from a few thousand dollars to well over $10,000 depending on complexity.
Once the agreement is drafted and reviewed, the grantor and trustee sign it. Most states require notarization, and some require witnesses. Keep the original secure and give copies to the trustee, successor trustee, and your attorney.
Getting an EIN for the Trust
An irrevocable business trust needs its own Employer Identification Number from the IRS. A revocable trust where the grantor is also the trustee can generally use the grantor’s Social Security number during the grantor’s lifetime, but a separate EIN is required once the grantor dies or the trust otherwise becomes irrevocable.2Internal Revenue Service. Instructions for Form SS-4
You apply online through the IRS at no cost. The application must be completed in a single session because you cannot save progress, and it times out after 15 minutes of inactivity. You will need the trust’s name as it appears on the agreement, the trustee’s name and address, and the Social Security number or taxpayer ID of the responsible party, which for a trust is the grantor. The IRS allows one EIN application per responsible party per day.3Internal Revenue Service. Get an Employer Identification Number
The trust must be legally formed before you apply. Submitting the EIN application before the trust agreement is executed can cause processing delays.
Funding the Trust
A signed trust agreement with no assets in it is an empty container. Funding is where people most often drop the ball, and any asset you forget to transfer stays outside the trust and remains subject to probate and creditor claims.
Funding means formally transferring ownership of each asset from you (or your existing entity) into the trust’s name. How you do that depends on the asset:
- Real estate. An attorney prepares a new deed transferring the property to the trust. Sign, notarize, and record the deed with the county recorder’s office. Notify your mortgage lender, property insurer, and local tax authority.
- Bank and investment accounts. Contact each institution to retitle the account in the trust’s name or open new trust accounts and move the funds over. Expect to provide a copy of the trust agreement or a trust certification.
- Business entity interests. To move LLC membership interests or corporate stock into the trust, execute an assignment document and update the entity’s operating agreement or corporate records.
- Vehicles and equipment. Retitle through the appropriate state agency and update insurance to name the trust as owner.
Review your asset list periodically and transfer newly acquired business property into the trust promptly. A trust only protects what it actually holds.
How the IRS Taxes a Business Trust
Tax treatment turns on whether the IRS classifies your trust as a grantor trust or a non-grantor trust, and this is where most business owners underestimate the complexity.
Grantor Trust Treatment
If you keep certain powers over the trust, the IRS treats you as the owner for income tax purposes no matter what the agreement says. Triggering powers include the ability to revoke the trust, control over who benefits from the trust’s income or assets, a reversionary interest worth more than 5 percent of the trust’s value, and the power to borrow from the trust without adequate security.4Office of the Law Revision Counsel. 26 USC Subtitle A, Chapter 1, Subchapter J, Part I, Subpart E Every revocable trust is a grantor trust by definition because the power to revoke is itself a triggering power.
In a grantor trust, income, deductions, and credits flow to your personal return, and the trust files no separate income tax. That simplifies life, but the trust delivers no income tax savings.
Non-Grantor Trust Brackets
An irrevocable trust where the grantor has given up enough control is a non-grantor trust, a separate taxpayer that files Form 1041. Trust brackets are heavily compressed. For 2026, the top 37 percent federal rate kicks in at just $16,000 of taxable income:5Internal Revenue Service. 2026 Form 1041-ES
- 10 percent on taxable income up to $3,300
- 24 percent from $3,300 to $11,700
- 35 percent from $11,700 to $16,000
- 37 percent over $16,000
An individual does not hit the 37 percent rate until well over $600,000 of income. Because of that gap, trustees often distribute income out to beneficiaries rather than accumulate it inside the trust. Distributed income is taxed at the beneficiary’s rate, which is almost always lower. The trustee issues a Schedule K-1 to each beneficiary showing their share of trust income, and a copy goes to the IRS with Form 1041.6Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1
Filing Deadline
Trusts generally use a calendar year. Form 1041 is due by the fifteenth day of the fourth month after the tax year ends, which is April 15 for most trusts.7Internal Revenue Service. Forms 1041 and 1041-A: When to File Filing Form 7004 extends the filing deadline to September 30, but not the deadline to pay.
Beneficial Ownership Reporting
As of March 2025, domestic entities, including business trusts formed in the United States, are exempt from the Corporate Transparency Act’s beneficial ownership information reporting requirements. FinCEN revised the rule so that only entities formed under foreign law and registered to do business in a U.S. state must file.8Financial Crimes Enforcement Network (FinCEN). Beneficial Ownership Information Frequently Asked Questions Earlier guidance saying domestic entities must report is out of date.
Ongoing Trustee Duties
Signing and funding are the start. A business trust needs continued attention to hold up legally and work in practice.
The trustee has a fiduciary duty that goes beyond following the trust agreement. That means acting with reasonable care, managing investments prudently by evaluating each one in the context of the whole portfolio, and putting beneficiaries’ interests ahead of the trustee’s own. A trustee who self-deals, takes excessive risks, or ignores administrative duties can be held personally liable.
Keep detailed records of every transaction, distribution, and change to assets or beneficiaries. If the trust runs an operating business, maintain separate books and separate bank accounts for trust activity. Commingling trust funds with personal funds is one of the fastest ways to undermine the trust’s protections.
Review the agreement periodically with your attorney. Tax laws change, family circumstances change, and business valuations shift. A revocable trust can be amended directly. An irrevocable trust may still be adjustable through decanting into a new trust or a trust protector’s modification powers if the agreement provides for one. And make sure the people who will need the trust, the successor trustee, key beneficiaries, and your professional advisors, know it exists and can find it when the time comes.
