Only Certain Trusts Qualify
An S corporation can have only eligible shareholders, and most trusts are not eligible. Put your stock in the wrong one and the company loses its S election and is taxed as a C corporation, for every owner. These are the trusts that work.
- A grantor trust (taxed to you while you live), which is what your revocable living trust is.
- A QSST (Qualified Subchapter S Trust).
- An ESBT (Electing Small Business Trust).
- Your estate, during a reasonable administration period, and a testamentary trust for up to two years.
Can a Revocable Trust Own S-Corp Stock After You Die?
A common question I hear is, "My shares are already in my living trust, so that is handled, right?" While you are alive, yes. The day you die is when it stops being handled.
What owners miss is the switch. Your revocable trust is a grantor trust while you are alive, so it holds the stock cleanly. But a trust stops being a grantor trust the moment you die. After death the trust can usually hold the stock for up to two years; to keep the S election alive past that, the trust (or the subtrusts that receive the stock) must qualify and make a QSST or ESBT election, generally within 2.5 months of the transfer. Miss it, and the S election terminates, turning the company into a C corporation for everyone. The documents looked fine while you were alive, which is exactly why the trap is so common.
Practice pointer. Write the 2.5-month election deadline into the trust instrument itself, next to the share transfer, rather than trusting anybody to remember it. The person who has to act is a grieving trustee or beneficiary who has never heard of a QSST, and the clock starts on a date nobody is thinking about.
QSST vs ESBT
| QSST | ESBT | |
|---|---|---|
| Beneficiaries | One income beneficiary (U.S. citizen/resident) | Multiple beneficiaries allowed |
| Income | All income distributed to the beneficiary | Can accumulate income |
| Tax on the S portion | At the beneficiary’s rate | At the top federal rate |
| Who elects | The beneficiary | The trustee |
| Good for | A single-beneficiary trust, lower tax | A discretionary or multi-beneficiary trust, flexibility |
A trust can sometimes be drafted to allow either election, so the family can choose at the right time. Each election has its own requirements, deadline and signer. See the QSST requirements and election, the ESBT rules and its flat 37% rate, or the five questions that decide between them.

Beyond death, watch for a shareholder marrying a non-resident alien or losing U.S. citizenship or residency; stock landing in an ineligible trust or with a foreign person; a second class of stock (different voting is fine, different distribution or liquidation rights are not); and a QTIP or marital trust that is not drafted to run like a QSST. Each can convert the company to a C corporation, for all owners, often before anyone notices.
Practice pointer. Ask your co-owners to tell you when any of these happens to them, and put it in the shareholders' agreement as a notice obligation. Your S election can be destroyed by a marriage or a move you never hear about, and the tax bill lands on every owner including the ones who did nothing.
If the Election Was Blown
Relief exists, at a cost. For a genuinely inadvertent termination, the IRS can grant relief under a simplified procedure (Rev. Proc. 2013-30) within roughly three years, or through a private letter ruling under Section 1362(f), which works but commonly runs $40,000 to $50,000 plus fees. The far cheaper path is drafting the trust correctly now. For owners who want outside investment or to give a key employee equity (which a plain S corp cannot do), restructuring into a holding-company structure can solve it.
Frequently Asked Questions
Can a Trust Own S-Corporation Stock?
Only certain trusts can. An S corporation can have only "eligible" shareholders, and most trusts are not on the list. The ones that work are a grantor trust (taxed to the living owner, which is what your revocable living trust is), a Qualified Subchapter S Trust (QSST), and an Electing Small Business Trust (ESBT). An estate can hold the stock during a reasonable administration period, and a testamentary trust for up to two years. Put S-corp stock into the wrong trust, and the corporation loses its S election and is taxed as a C corporation, for every owner.
What Happens to My S-Corp Stock When I Die?
Your revocable trust was a grantor trust while you were alive, which is fine. The problem is that a trust stops being a grantor trust the moment you die. After death, the trust can usually hold the stock for up to two years, but to keep the S election going past that, the trust (or the subtrusts that receive the stock) must qualify and make a QSST or ESBT election, generally within 2.5 months of the transfer. Miss the deadline and the company’s S election terminates. This is the trap most owners never see, because the documents looked fine while they were alive.
QSST vs ESBT: What’s the Difference?
A QSST can have only one income beneficiary (a U.S. citizen or resident), must distribute all of its income to that beneficiary, and is taxed at the beneficiary’s rate; the beneficiary makes the election. An ESBT is more flexible, it can have multiple beneficiaries and accumulate income, so it suits a discretionary or sprinkle trust, but the S-corporation portion is taxed at the top federal rate, which can cost more if the beneficiaries are in lower brackets. The trustee makes the ESBT election. Which one fits depends on your beneficiaries and your goals; a trust can sometimes be drafted to allow either.
What Else Can Terminate an S Election in Estate Planning?
Several quiet events can do it, including a shareholder marrying a non-resident alien or losing U.S. citizenship or residency (which can end grantor status and start a short election clock), stock landing in an ineligible trust or with a foreign person, creating a second class of stock (different voting rights are fine; different distribution or liquidation rights are not), and a QTIP or marital trust that is not drafted to run like a QSST. Each can convert the company to a C corporation, for all owners, often before anyone notices.
Can I Gift S-Corp Stock to a Trust During My Life?
Yes, if the trust qualifies, and the drafting is what carries the risk. A lifetime transfer works cleanly when the trust is a grantor trust (one taxed to you personally, which many irrevocable trusts used for gifting are drafted to be). A trust that is not taxed to you must qualify as a QSST or ESBT and make its election, generally within 2.5 months of the transfer, or the company’s S election terminates for every owner. And because grantor status can later end without warning, careful drafting plans the fallback election at the same time as the gift. We confirm the trust is eligible before a single share moves.
We Missed the Election, or the IRS Says We Terminated. Now What?
There is relief, but it costs time and money. For a genuinely inadvertent termination, the IRS can grant relief under a simplified procedure (Rev. Proc. 2013-30) within roughly three years, or through a private letter ruling under Section 1362(f), which works but commonly runs $40,000 to $50,000 plus professional fees. Separately, when S stock is transferred to a grantor trust, the IRS sometimes wrongly flags a termination; the fix is usually a rebuttal letter, not a crisis. The cheapest path by far is drafting the trust correctly in the first place.
How Do You Fix This in My Plan?
We make sure any trust that may hold your S-corp stock is drafted to be QSST-able or ESBT-eligible, with the right elections planned and the deadlines flagged, and we coordinate it with your buy-sell agreement and operating documents. For owners who want outside investment or to issue equity to a key employee, we can look at restructuring (for example, an F-reorganization into a holding company with a disregarded LLC underneath). It starts with reviewing what you have at a free consult.
Why Nobody Catches This Until It Is Expensive
The calls I take about this almost always come from an accountant rather than an owner, in the spring, after a return would not file the way it always had. By then the S election has usually been gone for a year or more and nobody in the company knows which event ended it.
In my practice the reason is structural rather than careless. The estate planning attorney drafted a good trust and never asked what the company was. The corporate attorney set up a clean S corporation and never asked where the shares would go at death. The accountant filed what he was handed. Three competent professionals, none of whom had the whole picture, and the one question that connects them takes about eight seconds to ask.
What I have not seen a document do is warn anybody about the calendar. A trust that qualifies as a QSST still terminates the election if nobody signs the election, and the signing falls to a beneficiary who has just buried a parent and has no idea the company's tax status is sitting in their hands with roughly two and a half months on it.
The arithmetic is what makes this worth an afternoon. Confirming a trust is eligible and drafting the fallback election costs a few hours of legal work at the planning stage. Fixing an inadvertent termination through a private letter ruling commonly runs $40,000 to $50,000 before professional fees, and the C-corporation tax in the meantime falls on every shareholder, including the ones who had nothing to do with your estate plan.
Avoid moving a single share into any trust before somebody has said out loud whether the company is an S corporation. Asked first, the question is free. Asked afterward, it is the most expensive sentence in the file.
