Yes, a trust can own stock, and this is one of the most common ways families hold investment portfolios for estate planning. The trustee takes legal title to the shares and manages them for the beneficiaries, which means dividends, voting rights, and sale proceeds all run through the trust. Whether that ownership saves you tax, avoids probate, or costs your heirs a step-up in basis depends entirely on the type of trust you use and how the shares are titled.
How a Trust Holds Shares
A trust is not a separate legal person the way a corporation is. It is a relationship created by a trust document, and that relationship splits ownership: the trustee holds legal title to the shares, and the beneficiaries hold equitable title, meaning the right to the economic benefits like dividends and appreciation.
This split only works if the shares are titled correctly. The brokerage account or stock certificate must be registered in the trustee’s name in a fiduciary capacity, not in the trust’s name alone. A proper registration reads something like “Jane Doe, Trustee of the Doe Family Trust dated January 1, 2024.” If the shares stay in an individual’s name, they remain personal property and will go through probate no matter what the trust document says.
The trustee can vote the shares, collect dividends, and sell positions, but only within the authority the trust document grants. A trust that limits the trustee to blue-chip stocks prohibits a shift into speculative positions. The document is the rulebook.
Revocable vs. Irrevocable Trusts
The type of trust you choose controls how much authority you keep over the stock and what tax treatment applies.
Revocable Trusts
A revocable trust lets the grantor keep complete authority. You can direct sales, change beneficiaries, swap investments, or dissolve the trust. The grantor and initial trustee are usually the same person, so managing the portfolio feels identical to owning the shares personally. The main benefit is probate avoidance: when the grantor dies, a named successor trustee takes over without court involvement. Because the grantor kept full control, the IRS treats the trust as invisible for income tax. Dividends, capital gains, and losses flow onto the grantor’s personal return under the grantor’s Social Security number.
Irrevocable Trusts
Transferring stock to an irrevocable trust permanently removes the shares from the grantor’s personal control. The grantor generally cannot direct sales, reclaim the assets, or change the terms without beneficiary consent or a court order. That loss of control buys tax benefits. Because the grantor no longer owns the assets, the stock can be excluded from the grantor’s taxable estate, which matters for estates approaching the federal estate tax exemption of roughly $14 million per person for 2026.
Within the irrevocable category, the IRS separates grantor trusts from non-grantor trusts. Some irrevocable trusts are intentionally structured so the grantor stays the deemed owner for income tax even after giving up control. These irrevocable grantor trusts still report all income on the grantor’s personal return. Most irrevocable trusts built for estate tax savings are non-grantor trusts, meaning the trust itself is a separate taxpayer with its own EIN and its own tax brackets.
Who Pays Income Tax on the Dividends and Gains
Grantor Trusts
All revocable trusts and some irrevocable trusts are grantor trusts for tax purposes. The IRS disregards the trust, and every dollar of dividend income, interest, and capital gains flows onto the grantor’s Form 1040. The trust does not file its own income tax return while the grantor is alive. This is the simplest arrangement.
Non-Grantor Trusts
When a trust is a separate taxpayer, the math changes sharply. Non-grantor trusts face the same federal rates as individuals, but the brackets compress into a tiny income range. For 2026, the 37% bracket starts at $16,000 of trust income. An individual doesn’t hit that rate until income exceeds roughly $626,000.1Internal Revenue Service. 2026 Form 1041-ES Estimated Income Tax for Estates and Trusts Long-term capital gains show the same compression: the 20% rate kicks in near $16,250 for trusts versus over $500,000 for most individuals. The 3.8% Net Investment Income Tax applies to trust income above the point where the top bracket begins, which is $16,000 for 2026.
This compression creates a strong pull toward distributing income. When the trustee distributes dividends or other income to a beneficiary, that income is taxed at the beneficiary’s individual rate instead of the trust’s. A beneficiary in the 12% or 22% bracket saves real money compared with the trust paying 37%. Distributed income is reported to each beneficiary on Schedule K-1, issued with the trust’s Form 1041.2Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 Income the trustee retains inside the trust is taxed at the trust’s rates.
What Happens to the Basis When the Grantor Dies
This is where trust structure has its largest long-term effect on the tax bill.
Stock held in a revocable trust is included in the grantor’s gross estate because the grantor kept control. That inclusion triggers a step-up in basis under Section 1014: the stock’s tax basis resets to fair market value on the date of death.3Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired From a Decedent Shares bought at $10 and worth $100 at death pass to the beneficiaries with a $100 basis. The $90 of appreciation is never taxed for income tax purposes.
Stock transferred to an irrevocable trust that is excluded from the grantor’s estate does not receive this step-up. The IRS confirmed this in Revenue Ruling 2023-2, holding that assets of an irrevocable grantor trust not included in the grantor’s gross estate do not qualify for a basis adjustment under Section 1014. Beneficiaries inherit the grantor’s original cost basis and owe capital gains tax on the full appreciation when they sell.3Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired From a Decedent
The nuance that catches people out: some irrevocable trusts are deliberately drafted so the assets are still included in the grantor’s estate, specifically to preserve the step-up. Section 1014(b)(9) provides that any property required to be included in the gross estate qualifies for the basis adjustment, regardless of trust structure. Whether an irrevocable trust’s assets land inside or outside the estate depends on the powers the grantor retains and the terms of the document. The estate tax versus capital gains tax trade-off is the core planning question.
S-Corporation Stock Has Its Own Rules
If you are thinking about putting S-corp shares into a trust, check eligibility first. The tax code strictly limits which entities can hold S-corp stock, and an ineligible shareholder terminates the S election entirely, forcing the company to be taxed as a C corporation. That hits every other shareholder too, not just the trust.
Only certain trust types qualify as eligible S-corp shareholders under Section 1361:4Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined
- Grantor trusts wholly owned by a U.S. citizen or resident individual. The deemed owner, not the trust, is treated as the shareholder.
- Former grantor trusts, which remain eligible for two years after the deemed owner’s death. After that window, the trust must convert to a QSST or ESBT or distribute the shares.
- Qualified Subchapter S Trusts (QSSTs), which must have a single U.S. citizen or resident income beneficiary, distribute all income currently, and limit any lifetime principal distributions to that same beneficiary. The beneficiary makes a separate QSST election for each S-corp stock the trust holds.
- Electing Small Business Trusts (ESBTs), which allow multiple beneficiaries but only individuals, estates, or certain charities, none of whom purchased their interest. The trustee files the ESBT election with the IRS, and S-corp income is taxed at the trust level at the highest individual rate.
- Voting trusts created primarily to exercise voting power over transferred stock.
Foreign trusts are flatly ineligible. A standard irrevocable non-grantor trust that does not qualify as a QSST or ESBT is also ineligible. The two-year window after a grantor’s death is a common trap: families assume they have time to sort things out, and the deadline passes without a QSST or ESBT election in place.
How to Move the Stock In
Get the Trust an EIN If It Needs One
Before transferring shares, the trust needs a taxpayer identification number. A revocable trust typically uses the grantor’s Social Security number while the grantor is alive. Non-grantor trusts and any trust that continues after the grantor’s death need their own Employer Identification Number, obtained by filing Form SS-4. You can apply online through the IRS website and receive the EIN immediately.5Internal Revenue Service. About Form SS-4, Application for Employer Identification Number
Publicly Traded Stock
Contact the brokerage firm holding the shares. The firm will ask for proof the trust exists and that the trustee has authority to act, usually the full trust agreement or a Certificate of Trust. The brokerage supplies transfer forms that require the exact registration title (including the trustee’s name and the trust’s date) and the trust’s TIN. Once processed, the account is re-titled in the trustee’s name.
Physical stock certificates require endorsement and a Medallion Signature Guarantee. This is a special stamp from a participating bank, credit union, or broker-dealer that verifies the signature and protects against unauthorized transfers.6Investor.gov. Medallion Signature Guarantees – Preventing the Unauthorized Transfer of Securities Transfer agents will not process the transaction without one.
Privately Held Company Stock
Transferring shares in a private company is more involved. Corporate bylaws, shareholder agreements, or operating agreements often include transfer restrictions such as rights of first refusal, board approval requirements, or outright prohibitions on transfers to certain entities. Review these documents before starting. You may need to notify the board and other shareholders, obtain written consent, and issue new certificates naming the trustee as owner. Skipping steps can void the transfer or trigger buyout provisions. An attorney familiar with trust law and corporate governance should review the transaction.
Foreign Stock Adds Reporting Requirements
If a trust holds stock through a foreign brokerage account or owns shares in a foreign corporation, additional federal reporting applies. Missing these filings triggers some of the steepest penalties in the tax code.
A trust with a financial interest in foreign accounts whose aggregate value exceeds $10,000 at any point during the year must file a Report of Foreign Bank and Financial Accounts (FBAR) with FinCEN.7Financial Crimes Enforcement Network. Report Foreign Bank and Financial Accounts Separately, certain domestic trusts holding specified foreign financial assets must file Form 8938 with the IRS if the total exceeds $50,000 on the last day of the tax year or $75,000 at any point during the year.8Internal Revenue Service. Instructions for Form 8938 These are independent requirements with different thresholds and different agencies. Filing one does not satisfy the other.
Penalties for failing to file Form 8938 start at $10,000 and can reach $60,000 if the IRS sends a notice and the form still is not filed within 90 days. If the trust owns shares in a foreign corporation and fails to file Form 5471, penalties start at $10,000 with additional $10,000 charges for each 30-day period of continued noncompliance, up to $50,000.9Internal Revenue Service.

What the Trustee Has to Do After the Shares Are In
Once the trust owns the stock, the trustee’s duties begin. Nearly every state has adopted a version of the Prudent Investor Rule, which requires managing the portfolio with the care a prudent investor would use. In practice, this means diversifying: a trustee who inherits a portfolio loaded with a single concentrated position generally has a duty to diversify over a reasonable timeframe. Holding the position because a family member always loved that stock is the kind of decision that exposes the trustee to personal liability if the price collapses. The duty is not absolute. A trust document that specifically authorizes a concentrated holding, or a legitimate reason not to sell such as triggering a large capital gains bill in a non-grantor trust, can justify keeping the position. The reasoning has to be documented.
The trustee also receives all corporate communications, proxy materials, and dividend payments. Voting is a fiduciary duty, not an optional task. Board elections, mergers, and compensation proposals must be evaluated in light of the beneficiaries’ interests. Some trust documents assign this authority to a designated investment advisor or trust protector.
On the tax side, a non-grantor trust files Form 1041 annually, reporting all income, deductions, gains, and losses from the portfolio.10Internal Revenue Service. About Form 1041, U.S. Income Tax Return for Estates and Trusts If the trustee distributes income, the trust issues a Schedule K-1 to each recipient. When a grantor dies and a formerly revocable trust becomes irrevocable, the trust needs its own EIN and must begin filing Form 1041. This transition catches many successor trustees off guard, because the trust operated invisibly for tax purposes during the grantor’s lifetime.
