To open a trust account, you bring three things to the bank: proof the trust exists and names you as trustee, a tax identification number for the trust, and your government-issued photo ID. Most banks can open the account in a single in-person appointment once those pieces are in hand. How to open a trust account depends slightly on whether the trust is revocable or irrevocable, because that distinction controls which tax ID the bank uses and how deposit insurance is calculated.
Documents to Gather Before the Appointment
The Trust Agreement or a Certification of Trust
The bank needs to see that the trust exists and that you have authority to open accounts in its name. You can prove this with the full trust agreement or with a shorter document called a certification of trust. More than 35 states have adopted some version of the Uniform Trust Code, which specifically authorizes the certification as a way to establish your authority without exposing private distribution terms.
A certification of trust usually states the date the trust was created, the name of the person who established it, the current trustee’s name and address, the trustee’s powers, whether the trust is revocable or irrevocable, and the trust’s tax ID number. It leaves out who inherits what.1Maine State Legislature. Maine Revised Statutes Title 18-B 1013 – Certification of Trust If an attorney drafted the trust, they can usually prepare the certification for you. Some banks will accept the full trust agreement instead, though the representative will typically photocopy only the pages that show the trustee’s powers.
The Right Tax ID Number
Not every trust needs its own tax ID, and this is where people get stuck.
If you created a revocable living trust and you’re still alive and serving as trustee, the bank uses your personal Social Security number on the account. The IRS treats a grantor-owned revocable trust as a disregarded entity, so it files no separate return and needs no separate number.2Internal Revenue Service. Employer Identification Number
An irrevocable trust is a separate taxable entity and needs its own Employer Identification Number. The same applies when a revocable trust becomes irrevocable after the grantor’s death; at that point, the grantor’s Social Security number can no longer be used, and the successor trustee has to get an EIN before the bank will allow further transactions.
The fastest way to get an EIN is the IRS online application, which is free and issues the number immediately. You can also apply by fax or mail using Form SS-4, but those methods take days or weeks.3Internal Revenue Service. Get an Employer Identification Number You’ll need the trust’s legal name, the type of trust, and the Social Security number of the responsible party. If the bank doesn’t receive a valid tax ID, it must withhold 24 percent of any interest the account earns and send it to the IRS as backup withholding.4Internal Revenue Service. Topic No. 307, Backup Withholding
Your Photo ID
Federal anti-money-laundering rules require banks to run a Customer Identification Program on every new account. For a trust account, that means the bank verifies both the trust and you as trustee. Bring unexpired government-issued photo ID such as a driver’s license or passport, along with your Social Security number, date of birth, and home address. The bank will also record the trust’s name, principal address, and taxpayer identification number.5eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks Every name on your ID must match the trust document exactly. A middle initial on your license that doesn’t appear in the trust agreement can stall the process.
Choosing Where to Open the Account
Banks, credit unions, and brokerage firms all offer trust accounts. A large commercial bank typically has stronger online fiduciary banking tools and handles wires and automated bill pay smoothly. A local credit union may charge lower fees and require smaller minimum balances, but its digital features can be limited. If the trust holds stocks, bonds, or mutual funds rather than just cash, a brokerage firm is usually the better fit because it can hold those securities and cash under the trust’s name in one place.
The trust document itself often points to the account type. If the trust pays recurring expenses like property taxes or a beneficiary’s living costs, a checking account fits. If the trust is holding funds long-term with no near-term distributions, a savings or money market account earns more interest while staying accessible. A trustee has a legal duty to manage assets prudently, which means avoiding unnecessary fees and not parking large balances in accounts earning nothing. Read the trust’s investment and distribution provisions before choosing.
What Happens at the Bank
Most banks still require an in-person appointment to open a trust account. The representative reviews the certification of trust or the full trust agreement to confirm your authority, enters the trust’s information into the bank’s system, and generates a signature card. You sign it not personally but as trustee. The bank keeps the card on file to verify future checks and withdrawals.
Get the account title right at this stage. It should mirror the exact name on the trust document, typically something like “Jane Smith, Trustee of the Smith Family Trust dated January 15, 2024.” A title mismatch can create problems at tax time and weakens the legal separation between trust assets and your personal finances.
Funding the Account and Retitling Other Assets
A trust account is an empty shell until money goes in. You can make the initial deposit with a personal check, wire transfer, or cash. Banks generally require a minimum opening balance, which ranges from a nominal amount to several thousand dollars depending on the account tier. Once the deposit clears, you can begin setting up transfers into the account.
Cash is the easy part. The harder work is retitling non-cash assets into the trust’s name. For brokerage holdings, you typically open a new trust brokerage account at the same firm and request an internal transfer, which moves the securities without triggering a sale. The firm will need a copy of the trust document. For real estate, you’ll need a new deed, usually a quitclaim deed or grant deed depending on your state, transferring title from your individual name to the trust. The deed must be notarized and recorded with the county recorder’s office. Vehicles, business interests, and other titled property each have their own retitling process through the relevant agency or transfer agent.
This funding step is where people most often drop the ball. Signing a trust document and opening the bank account accomplishes nothing if you never move assets into the trust’s name. Property left in your individual name stays outside the trust, exposed to probate and potentially beyond the trustee’s control.
Deposit Insurance on Trust Accounts
Trust accounts at FDIC-insured banks get more deposit insurance coverage than a standard personal account. Rather than the usual $250,000 per depositor, a trust account is insured up to $250,000 per eligible beneficiary, with a maximum of $1,250,000 per trust owner when five or more beneficiaries are named.6FDIC. Trust Accounts A trust with three beneficiaries would be insured up to $750,000 at a single bank.
Credit union trust accounts work the same way. The National Credit Union Share Insurance Fund covers revocable trust accounts at $250,000 per beneficiary, calculated on the same formula.7National Credit Union Administration. Share Insurance Coverage If the trust holds more than the insured maximum, consider spreading deposits across institutions. This higher coverage applies automatically based on the trust’s beneficiary designations, but the bank does need to know the account is held in trust.
Tax Reporting After the Account Is Open
A revocable trust during the grantor’s lifetime creates no separate tax obligations. All income earned in the trust account is reported on the grantor’s personal return under their Social Security number, and there’s no separate trust return to file.
Once a trust becomes irrevocable, either by design or because the grantor has died, it becomes its own taxpayer. If the trust earns $600 or more in gross income during the tax year, the trustee must file Form 1041 with the IRS.8Internal Revenue Service. 2025 Instructions for Form 1041 The trust also issues Schedule K-1 forms to beneficiaries who receive distributions, since income generally passes through to them for tax purposes. If you’re stepping into the trustee role after someone’s death, an accountant familiar with fiduciary returns is worth the cost. The rules around distributable net income and the compressed trust tax brackets are genuinely complex, and mistakes are expensive.
Successor and Co-Trustee Situations
If you’re taking over an existing trust account rather than opening a new one, the bank will want a certified copy of the death certificate or medical certification of incapacity, the trust document showing you as the named successor, and often a signed affidavit confirming that you’ve accepted the role. If the trust was revocable and the grantor has died, you’ll also need a new EIN before the bank allows ongoing transactions.2Internal Revenue Service. Employer Identification Number Some banks process the changeover in a single visit; others send the trust document to their legal department, which can add a week or more. Bringing both the full trust agreement and a certification of trust gives them everything at once.
When two or more co-trustees are named, the bank needs to know whether each can act independently or whether they must act together. This matters more than people expect. Many financial institutions prefer, and some insist, that the trust allow each co-trustee to act alone, because they don’t want to verify dual signatures on every transaction. If the trust requires joint action and the bank won’t accommodate that, the co-trustees can end up unable to access the account without both being present. Sorting this out in the trust document before opening the account avoids a real headache later.
