To open a trustee bank account, you need the trust’s tax identification number, documentation proving the trust exists and that you have authority to act for it, and valid personal ID — then you book an in-person appointment with the bank and open the account titled in the trust’s name. Most banks still require that meeting rather than an online application, and the account title is what keeps trust assets legally separate from your own. The rest is detail, but the details are where first-time trustees get tripped up.
Which Tax ID the Account Uses
Every trust account needs a taxpayer identification number. Which one depends on whether the trust is revocable and whether the grantor is still living.
A revocable living trust with a living grantor uses the grantor’s Social Security Number. The IRS treats this kind of trust as an extension of the grantor, so income flows through to the grantor’s personal return and no separate tax ID is needed.
Once the grantor dies, or the trust becomes irrevocable for any other reason, the trust needs its own Employer Identification Number (EIN). You can apply online at IRS.gov for free and receive it immediately, or file a paper Form SS-4 by mail or fax, which takes weeks instead of minutes.1Internal Revenue Service. About Form SS-4, Application for Employer Identification Number (EIN) Getting the EIN is one of the first things a successor trustee should do after a grantor’s death, because the bank will not open or retitle an account without it.
If you are stepping in after a grantor’s death, also file IRS Form 56 to notify the IRS of the fiduciary relationship and identify yourself as responsible for the trust’s tax obligations.2Internal Revenue Service. Instructions for Form 56
What To Bring to the Bank
Pull everything together before the appointment. A missing document usually means rescheduling.
- Government-issued photo ID (passport or driver’s license) for every person who will sign on the account.
- The trust’s tax ID — the grantor’s SSN for a revocable trust with a living grantor, or the trust’s EIN.
- Trust documentation: either a full copy of the trust instrument or a Certification of Trust.
- The full legal name of the grantor, plus a certified copy of the death certificate if the grantor has died.
- Proof of address, such as a recent utility bill or bank statement matching the trustee’s current address.
Some banks also ask for the Social Security Numbers of trust beneficiaries. The Office of the Comptroller of the Currency has confirmed that national banks may require a beneficiary’s SSN for monetary transactions related to a trust.3HelpWithMyBank.gov. Can a Bank Require a Beneficiary to Provide a Social Security Number? Not every bank asks for this upfront, but having it on hand saves a return trip.
Using a Certification of Trust Instead of the Full Document
You do not have to hand over the full trust instrument. The Uniform Trust Code, adopted in some form by a majority of states, lets a trustee give the bank a Certification of Trust instead — a condensed summary that proves what the bank needs to know without disclosing private terms like distribution amounts or beneficiary conditions.
A proper certification includes the date the trust was created, the names and addresses of the current trustees, whether the trust is revocable or irrevocable, the powers the trustees hold, and the trust’s taxpayer identification number. It also specifies whether all co-trustees must sign off on transactions or whether any one of them can act alone.4Uniform Law Commission. Uniform Trust Code – Section 1013 Certification of Trust Banks that rely on a certification in good faith are protected by law even if it later turns out to contain an error, which is why most are comfortable accepting one.
Some banks have their own certification form; others accept one prepared by an attorney. Either way, the formal trust name on the certification must match the original trust instrument exactly, including the date. Small discrepancies between the certification and the bank’s own application will delay things.
What Happens at the Appointment
Most banks still require an in-person meeting to open a trust account. Chase, for example, states explicitly that trust accounts cannot be opened online and require a meeting with a banker.5Chase. Open a Trust Account A few online banks now allow digital submissions with high-resolution scans of the trust documents, but that remains the exception.
At the appointment, the banker reviews your ID, trust documentation, and tax ID. You then sign a signature card that establishes who is authorized to write checks, initiate transfers, and otherwise conduct business on the account. After submission, the bank’s compliance department performs a secondary review of the trust’s validity, and the account is usually fully active within a few business days. Hold off on large transactions or wire transfers until you have written confirmation the account is open.
You can open most standard account types in a trust’s name: checking, savings, certificates of deposit, and money market accounts. Which ones you need depends on what the trust is doing. A trust paying ongoing expenses needs a checking account; one holding assets for long-term growth might start with savings or a money market account.
Titling the Account Correctly
This is where people make the most costly mistakes. The account title is what legally separates trust property from your personal assets. A poorly titled account can lose its creditor protection, create confusion during audits, and cause problems when the trust eventually distributes.
The standard format includes the trustee’s name, their capacity as trustee, and a reference to the trust with its date. When the grantor is also the trustee, that reads something like: “John Smith, Trustee Under Declaration of Trust Dated March 15, 2020.” When the trustee and grantor are different people, the form is typically: “Jane Smith, Trustee Under Agreement with John Smith Dated March 15, 2020.”6TreasuryDirect. FS Publication 0049 – Registration of Trust The exact wording should match what the trust document specifies. Any checks or debit cards issued for the account should also carry the trust name and your representative capacity, so every payment is clearly identifiable as a trust expenditure.
Extra Steps for a Successor Trustee
If you are opening or retitling an account as a successor trustee after the original trustee has died or become incapacitated, the bank will want proof that the prior trustee’s authority has ended and yours has begun.
You will typically need the trust pages showing your appointment as successor, a certified death certificate or documentation of the prior trustee’s incapacity, and the trust’s new EIN if the trust had been using the deceased grantor’s Social Security Number. Many banks accept the relevant pages rather than the full instrument, since a trust is a private document and the bank has no right to review provisions unrelated to your authority.
This is also when you file Form 56 with the IRS to establish yourself as the responsible fiduciary.2Internal Revenue Service. Instructions for Form 56 If the prior trustee held accounts at several institutions, each bank will run its own verification. Order at least ten certified copies of any death certificate. They get used up faster than most people expect.
Keeping Trust Funds Separate Once the Account Is Open
Opening the account correctly only matters if you then use it correctly. A trustee has a fiduciary duty to manage trust property solely in the interests of the beneficiaries, and that includes never mixing trust money with personal funds.7Cornell Law Institute. Commingling Depositing trust income into a personal account, paying personal expenses from the trust account, or even temporarily parking personal money in the trust account can all count as commingling.
The Uniform Trust Code requires trustees to keep adequate records and to keep trust property designated so that the trust’s interest appears in the records of banks, brokerages, and other third parties.8Uniform Law Commission. Uniform Trust Code – Section 810 Recordkeeping and Identification of Trust Property A trustee who breaches that duty can be held personally liable to the beneficiaries for resulting losses, removed from the role, or ordered by a court to repay what was mismanaged. Proper titling at opening and disciplined record-keeping afterward are your main defense if a beneficiary ever questions how you handled the money.
