QSST - S Corp Stock in a Trust
(Individual)
If you own S corporation stock held in a trust, or you’re planning to set one up, a QSST election keeps the income taxed at the beneficiary’s rate instead of 37%. We handle the return and the coordination.

You own an S corp and a trust is part of the plan
If you own shares in an S corporation and you’re thinking about estate planning, whether passing the stock to your kids, protecting assets, or keeping the business in the family, the trust you set up needs to be an eligible S corp shareholder. Most trusts aren’t, unless they make an election. A qualifying subchapter S trust (QSST) is one of the two elections available, and it’s often the better choice when the trust has a single beneficiary.
The reason: with a QSST, the S corporation income is taxed at the beneficiary’s individual rate, not at the trust level at 37%, which is what happens with the other option (an ESBT). If the beneficiary is in a lower bracket, that’s a real savings.
How a QSST works
The QSST election treats the beneficiary as the owner of the S corp stock for income tax purposes. The S corporation’s income, deductions, and credits flow directly to the beneficiary’s personal Form 1040, as if they held the stock themselves. The trust still exists as the legal owner, but for tax purposes, the beneficiary reports the S corp income.
The trust itself still files Form 1041 for any non-S corp income, interest on a trust bank account and dividends from other investments, but the S corp portion bypasses the trust’s return entirely.
The requirements are strict
A QSST only works if the trust meets several conditions:
- One current income beneficiary: the trust can only have a single person entitled to receive distributions during their lifetime
- All income distributed currently: the trust must distribute (or be required to distribute) all its accounting income to that beneficiary each year
- Corpus to that beneficiary only: any distributions of principal during the beneficiary’s lifetime can only go to them
- U.S. person: the beneficiary must be a U.S. citizen or resident
If the trust has multiple beneficiaries or allows discretionary accumulation, it doesn’t qualify. The ESBT election is the fallback, more flexible, but the S corp income gets taxed at 37%. If you’re drafting a new trust to hold S corp stock, your attorney can structure it to meet the QSST requirements if that’s the tax result you want.
QSST vs. ESBT - which makes sense for you?
The decision comes down to structure and math:
- QSST: S corp income taxed at the beneficiary’s rate. Simpler return. But the trust must have one beneficiary and distribute all income. Less flexibility.
- ESBT: S corp income taxed at 37% at the trust level. Multiple beneficiaries allowed. Discretionary distributions. More flexibility, higher tax cost.
If you’re setting up a trust for one child to inherit the family business, a QSST is often the right call. If you’re setting up a trust for three children with the trustee deciding who gets what, you need an ESBT. We can model the actual tax difference for your situation.
If you’re already the beneficiary
If a QSST election has already been made and you’re receiving S corp income on your 1040, we make sure the K-1 items land correctly. You may get a K-1 from the S corp directly, or the trust may pass the items through on its own K-1; either way, the income goes on your personal return at your rate. If the trust also distributes non-S corp income, that’s a separate K-1 from the trust.
What we need from you
- Your personal income documents (W-2s, 1099s, other K-1s)
- S corporation K-1 (whether issued to you or to the trust)
- Trust document (to confirm QSST eligibility)
- K-1 from the trust for non-S corp income (if any)
- Prior year return for reference
Frequently Asked Questions
I own an S corp. Should I consider a QSST?
If you’re planning to put S corp stock into a trust and the trust will have a single beneficiary who receives all the income, a QSST is worth considering. The S corporation income gets taxed at the beneficiary’s individual rate, which is usually much lower than the 37% flat rate an ESBT would pay. The tradeoff is that the trust structure has to meet strict requirements: one current income beneficiary, all income distributed currently, and corpus distributions only to that beneficiary during their lifetime. Talk to your attorney about whether the trust can be drafted to qualify.
How is the S corp income taxed with a QSST?
The S corporation income flows directly to the beneficiary and is taxed on their personal Form 1040, as if they owned the stock themselves. The trust still files its own return (Form 1041) for any non-S corp income, but the S corp portion bypasses the trust entirely for income tax purposes. This is the key advantage over an ESBT, which taxes the S corp income at 37% at the trust level.
What if the trust has more than one beneficiary?
A QSST must have exactly one current income beneficiary. If the trust has multiple beneficiaries, even if only one is currently receiving distributions, it can’t be a QSST. In that case, the ESBT election is the only option. If you’re setting up a new trust and want QSST treatment, the trust needs to be drafted with a single beneficiary from the start.
I’m the beneficiary of a QSST. What do I need to know?
The S corp income shows up on your personal 1040; you’ll receive a K-1 from the S corporation or from the trust. You may also receive a separate K-1 from the trust for non-S corp income (interest, dividends from other trust assets). Both go on your return. The advantage is that the income is taxed at your rate, not the trust’s. We make sure all the K-1 items land on the right lines.
