Does S-Corp Stock Go Through Probate?

Yes, Unless the Owner Planned Around It

S-corporation stock is personal property, and like all personal property, it passes through probate if the deceased held it in their individual name with no transfer mechanism in place. The shares go into the estate, the executor manages them during the probate period, and they are eventually distributed to the beneficiaries named in the will — or to the intestate heirs if there is no will.

The exceptions are the same ones that apply to any asset:

• Revocable living trust: If the shares were titled in the name of a trust, they transfer to the successor trustee outside of probate
• Community property with right of survivorship: In community property states, shares held as community property with survivorship transfer directly to the surviving spouse
• Buy-sell agreement with funded mechanism: A properly structured cross-purchase agreement transfers shares directly to the surviving shareholders upon death, funded by life insurance proceeds

If none of these apply, the shares go through probate. The practical impact: the personal representative generally needs court appointment and Letters Testamentary to act for the estate's shares. Depending on state law and the case, opening probate often takes 30 to 90 days.

The S-Election Preservation Problem

Here is where S-corp stock gets more complicated than ordinary probate assets. The IRS imposes strict eligibility requirements on who can hold S-corporation shares. Eligible shareholders include:

• U.S. citizens and resident aliens (not nonresident aliens)
• Estates (while in administration)
• Certain types of trusts (Qualified Subchapter S Trusts, Electing Small Business Trusts, grantor trusts, and testamentary trusts for a limited period)
• Tax-exempt organizations under Sections 401(a) and 501(c)(3)

Ineligible shareholders include non-resident aliens, partnerships, corporations, and most irrevocable trusts that do not qualify as a QSST or ESBT.

If S-corp shares pass — through probate or any other mechanism — to an ineligible shareholder, the S-election terminates. Not just for that shareholder's portion. The entire corporation loses its S status and reverts to a C-corporation, effective on the date the ineligible transfer occurs.

The consequences of losing S-corp status are severe. C-corporations pay tax at the entity level and shareholders pay tax again on distributions, creating double taxation. Any built-in gains from the S-corp period may be taxed at the corporate level. And once the S-election is lost, the corporation cannot re-elect S status for five years without IRS consent.

Common Scenarios That Trigger Ineligibility

The deceased's spouse is a nonresident alien. If the will leaves the S-corp shares to a nonresident alien spouse, the S-election terminates when the shares pass to that ineligible shareholder. A trust may be an option only if it independently qualifies as an eligible S-corp shareholder; confirm the structure with an estate and tax professional.

The will directs shares to a family trust that is not S-corp eligible. Many estate plans include irrevocable trusts for tax planning or asset protection. Unless the trust document specifically includes QSST or ESBT language, it is not an eligible S-corp shareholder.

Intestate succession distributes shares to an ineligible heir. When the deceased dies without a will, state intestacy law controls distribution. If any heir in the intestacy chain is ineligible (a non-resident alien relative, for example), the shares cannot pass to them without terminating the S-election.

What the Executor Must Do

The moment the executor learns that S-corp stock is part of the estate, three things need to happen:

Verify eligibility of all beneficiaries. Before distributing any shares, confirm that every intended recipient is an eligible S-corp shareholder. If any are not, work with an attorney to structure the transfer through an eligible trust.

File a QSST or ESBT election if needed. If shares will pass to a trust, the income beneficiary or legal representative (for a QSST) or the trustee (for an ESBT) generally must file the election within the 16-day-and-two-month period beginning on the day the stock is transferred to the trust.

Monitor the two-year testamentary trust window. A testamentary trust that receives stock under the deceased's will is automatically eligible to hold S-corp stock for two years beginning on the day the stock is transferred to the trust. After that, the trust must qualify as a QSST or ESBT, or the shares must be distributed to an eligible shareholder. Missing this two-year deadline terminates the S-election.

The Estate Itself Is a Temporary Safe Harbor

One piece of good news: the estate is an eligible S-corp shareholder for the entire period of administration. While the estate is open, the shares are safe from triggering an ineligibility event. This gives the executor time to plan the distribution carefully.

Federal tax law sets no fixed 12-to-24-month deadline for distributing the shares. The executor should administer the estate under state law and plan with a tax professional before distributing stock to a beneficiary or trust.
