To open a trust brokerage account, you gather the trust document (or a certification of trust), obtain the correct tax identification number for the trust, choose a brokerage firm that handles fiduciary accounts, complete the application with the trust titled exactly as its governing document requires, and fund the account. Most trustees finish the process in a few weeks. Irrevocable trusts usually take longer because the brokerage firm’s compliance team reads the document more closely.
The steps below assume you are the trustee, or are about to be. If you are the grantor of a revocable living trust and also serve as your own trustee, the process is short. If you are opening an account for an irrevocable trust, or stepping in as successor trustee after someone has died, several extra pieces have to be in place before the firm will let you trade.
Start With the Trust Type: Revocable or Irrevocable
The first question the brokerage firm will ask is which kind of trust it is, because that answer decides what tax ID goes on the application.
A revocable living trust is one the grantor can change or dissolve at any time. Because the grantor retains that control, the IRS treats the trust as if it doesn’t exist for income tax purposes during the grantor’s lifetime, and investment income flows through to the grantor’s personal return.1Internal Revenue Service. Abusive Trust Tax Evasion Schemes – Questions and Answers For a revocable trust where the grantor is alive and serving as trustee, most brokerage firms open the account using the grantor’s Social Security Number. No separate tax ID is needed.
An irrevocable trust is a permanent transfer. The grantor has given up ownership, so the trust is its own taxpayer. Before you can open the account you need an Employer Identification Number for the trust. The fastest route is the IRS online application, which issues the number immediately.2Internal Revenue Service. Get an Employer Identification Number You can also apply on paper with Form SS-4, but that takes days or weeks.3Internal Revenue Service. Instructions for Form SS-4
Brokerage firms review irrevocable trust applications more closely because the trustee’s authority is narrower and defined entirely by what the trust document says. Expect the compliance team to actually read the provisions on trustee powers.
Documents to Have Ready Before You Apply
If you assemble everything before contacting the firm, the application usually moves in one pass instead of stalling for weeks.
The Trust Document or a Certification of Trust
The firm needs proof the trust exists and that you’re authorized to act as trustee. Most firms accept a certification of trust, sometimes called a trust abstract, instead of the full trust agreement. A certification is a condensed version confirming the trust’s name, its date, the trustee’s identity, and the trustee’s powers, while omitting private matters like beneficiary names and distribution terms. That protects the grantor’s privacy while giving the firm what it needs.
A firm can still insist on the full trust agreement. It’s within their rights, though uncommon for standard accounts. Have both versions ready.
The Tax Identification Number
For a living revocable trust, that’s the grantor’s Social Security Number. For an irrevocable trust, it’s the EIN you obtained from the IRS. Enter it exactly as it was issued.
Trustee Identification
Every acting trustee has to provide a government-issued photo ID, such as a driver’s license or passport. Co-trustees each provide their own. This comes from federal anti-money-laundering rules that require financial institutions to verify the identity of anyone with authority over an account.4FFIEC BSA/AML InfoBase. FFIEC BSA/AML Manual – Trust and Asset Management Services
Getting the Account Title Exactly Right
Incorrect titling is one of the most common reasons brokerage firms reject trust account applications. A sloppy title can also create real legal trouble later if anyone challenges whether an asset actually belongs to the trust.
The standard format includes the trust’s full legal name, the date it was created, and the trustee’s name. For example:
The Jane Doe Family Trust dated October 15, 2018, John Smith, Trustee
If there are co-trustees, list both: John Smith and Mary Smith, Co-Trustees. The application will have separate fields for the trust name, date, trustee name, and tax ID. Copy the trust name exactly as it appears in the trust document, including any leading “The.” Small discrepancies between the account title and the trust document cause problems later when you transfer assets, add accounts, or hand things over to a successor trustee.
Choosing a Brokerage Firm
Not every brokerage firm handles trust accounts well. The major online discount brokerages all offer them, but their support for anything nonstandard varies widely. A few things to weigh:
- Fiduciary account experience. A firm that regularly handles trust accounts will have staff who understand distributing income to beneficiaries, processing trustee changes, and producing the right tax documents. Firms that treat trust accounts as an afterthought create months of frustration when something unusual comes up.
- Fees. Some firms charge higher account maintenance fees for trust accounts than for individual ones; others charge the same. Ask specifically about annual account fees, trade commissions, and whether the firm charges extra for trust-specific services like annual accountings or trustee changes.
- Investment options. A trustee has a fiduciary duty to diversify the portfolio unless the trust document says otherwise. The platform needs a broad enough range of stocks, bonds, mutual funds, and other asset classes to build a properly diversified portfolio.
- Margin and options. Most trust accounts are cash-only by default. If the trust document authorizes margin borrowing, the firm will want to see that language before enabling it. Even when it’s authorized, leverage in a trust carries heightened fiduciary risk and needs a documented reason.
Submitting the Application
Once you’ve picked a firm and gathered your documents, the application itself is mostly paperwork. Many firms let you enter the data online, though the trust certification and trustee ID usually need to be uploaded as scans or dropped off in person. The compliance team then reviews everything to verify the trustee’s authority and the trust’s legal standing.
Expect that review to take anywhere from a few days to a couple of weeks. Irrevocable trusts with unusual provisions run longer. If the reviewer flags a discrepancy between the certification and the application (a mismatched date, a missing co-trustee, a name that doesn’t match the tax ID records), fix it right away rather than trying to argue past it.
Funding the New Account
After approval, you move money or securities in. For cash, there are two normal options:
- ACH transfer. Free at most firms, one to three business days to settle.
- Wire transfer. Same-day arrival, but banks typically charge $15 to $50 per wire.
Money transferred in should come from an account already titled in the name of the trust, or should be accompanied by documentation showing the deposit is a contribution to the trust. Mixing personal funds into a trust brokerage account without a clear paper trail is one of the fastest ways for a trustee to create later problems.
If you’re moving an existing investment portfolio from another brokerage firm, you use the Automated Customer Account Transfer Service, or ACATS. This system transfers securities without liquidating them, which preserves the existing cost basis and avoids triggering taxable events. You start the transfer at the receiving firm and provide the old account number and a recent statement.5FINRA. Customer Account Transfers
Under FINRA rules, the delivering firm has three business days to validate the transfer instruction and three more business days to complete it after validation.6FINRA. FINRA Rule 11870 – Customer Account Transfer Contracts The full process usually runs one to two weeks once you count paperwork on both ends. Certain asset types, like limited partnerships or proprietary mutual funds, can cause delays or fail to transfer at all.
Who Does What Once the Account Is Open
Every trust brokerage account involves four roles, and it helps to keep them straight when talking to the firm.
The grantor (sometimes called the settlor) is the person who created the trust and contributed the assets. In many revocable trusts the grantor also serves as the initial trustee.
The trustee manages the account: makes investment decisions, executes trades, files tax returns, and distributes income or principal to beneficiaries according to the trust document. The trustee owes a legal duty of loyalty and prudence, meaning acting solely in the beneficiaries’ interest and investing with the care a reasonable person would apply to someone else’s money.7Office of the Law Revision Counsel. 26 USC 676 – Power to Revoke
The beneficiaries are the individuals or entities entitled to receive income or assets from the trust. Some receive income during the trust’s existence; others receive whatever remains when it terminates.
The brokerage firm holds the securities, executes trades the trustee directs, and issues tax reporting documents. Its relationship is with the trust as an entity, represented by whoever is serving as trustee at any given time.
What Changes When the Grantor of a Revocable Trust Dies
If you’re opening a revocable trust brokerage account now with the grantor’s Social Security Number, know that the setup changes the moment the grantor dies. This trips up a lot of successor trustees, so it’s worth flagging even at the opening stage.
On the grantor’s death the revocable trust becomes irrevocable. The trust is now its own taxpayer, and the successor trustee must obtain a new EIN because the grantor’s SSN can no longer be used.2Internal Revenue Service. Get an Employer Identification Number The brokerage firm will want the new EIN, the grantor’s death certificate, and documentation establishing the successor trustee’s authority before allowing the successor to trade.
The trust’s assets generally receive a stepped-up cost basis to their fair market value as of the grantor’s date of death under IRC Section 1014.8Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent The successor trustee should work with the brokerage firm to update the basis records, because the firm’s records will still show the original purchase price.
From that point forward the trust files its own return on Form 1041 and pays tax under compressed brackets that reach the top federal rate at a fraction of the income an individual would need to earn.9Internal Revenue Service. About Form 1041, U.S. Income Tax Return for Estates and Trusts Understanding that shift matters when you’re setting up the account, because the same brokerage account that quietly reported to a Form 1040 during the grantor’s life will face a very different tax picture the year after the grantor dies.
