For years, S corporations have been the entity of choice for many closely held businesses. The structure offers pass-through taxation, generally avoids a second layer of tax and provides operational flexibility. But as founders of S corporations begin planning for a future sale, many discover one of the most powerful tax incentives available to business owners is not available to shareholders in S corporations — the Qualified Small Business Stock (QSBS) exclusion under Section 1202.
Under the right circumstances, Section 1202 can allow shareholders to exclude a substantial amount of gain from federal income tax when they sell qualifying stock. The potential benefit is significant enough that many S corporation owners ask the same question: Can an existing S corporation be converted into a structure that qualifies for QSBS?
The answer is yes — but with an important caveat. The path is not as simple as revoking an S election and waiting three to five years to sell their stock.
Section 1202 provides the full or partial exclusion of capital gain realized on the sale of QSBS that is held at least three years. There are requirements that apply to the company that issued the QSBS, and requirements that apply to the shareholder that is selling the QSBS. If these requirements are met, then the selling shareholder can exclude from gross income capital gain in an amount equal to the greater of (i) $15 million or (ii) an annual exclusion of 10 times their basis in the stock sold (for an exclusion amount up to $750 million). There are also specific tax strategies, like stacking and packing, that enable selling shareholders to magnify the tax benefits.
For stock issued on or before July 4, 2025, the exclusion amount is the greater of $10 million or 10 times basis, and the holding period is five years.
The starting point for any QSBS discussion is understanding one critical rule: stock issued by an S corporation can never be QSBS. Even if the entity later converts to a C corporation, the shares originally issued while the company was an S corporation remain permanently tainted for Section 1202 purposes.
That rule surprises many business owners. A common misconception is that converting an S corporation into a C corporation creates QSBS eligibility for existing owners. It does not.
By contrast, a corporation that originally issued stock while it was a C corporation generally can elect S status and later return to C corporation status without destroying QSBS treatment, provided the corporation was classified as a C corporation during substantially all (generally about 80%) of the shareholder’s holding period.
For existing S corporations, the challenge is therefore not preserving QSBS — it is creating it. Below are some options to create QSBS for holders of stock in an S corporation.
The most straightforward approach is to terminate the S election and operate as a C corporation going forward. Once the company becomes a C corporation, it may issue new shares in exchange for fair market value consideration, and those newly issued shares may qualify as QSBS if the remaining requirements of Section 1202 are satisfied.
The important limitation is that the original S corporation shares do not become QSBS. Only the newly issued stock has the potential to qualify. The pre-conversion stock remains ineligible regardless of how long it is held after the conversion.
For some businesses, particularly those expecting additional investors or future equity issuances, this can be a workable solution. For others, it may provide limited value because the founders do not receive QSBS treatment.
A more sophisticated approach involves moving the operating business into a newly formed C corporation through a Section 351 contribution.
Under this structure, the S corporation contributes its assets to a new C corporation in exchange for stock. Because the new stock is issued by a C corporation, the resulting shares may qualify as QSBS. However, this strategy comes with several significant technical considerations.
First, the S corporation cannot simply distribute the C corporation stock to its shareholders. This means that the QSBS must be held inside the S corporation.
Second, dividends received from the C corporation may constitute passive investment income. If the S corporation has accumulated earnings and profits from prior C corporation years, excessive passive income can trigger an entity-level tax and, in some circumstances, threaten the S election itself.
Third, business considerations often become just as important as tax considerations. A direct asset transfer to a new C corporation may affect licenses, customer contracts, permits, employee benefit arrangements, financing agreements, and other legal relationships. For that reason, an F reorganization is typically recommended before implementing the Section 351 transaction.
In a typical F reorganization, shareholders contribute their S corporation stock to a newly formed corporation (Holdco), and the original S corporation subsequently becomes a qualified subchapter S subsidiary (QSub) of Holdco, which is treated as a disregarded entity into Holdco for tax purposes.
After the F reorganization is complete, Holdco converts the QSub to a single-member LLC, which is a tax-free transaction, and then either contributes the equity in the LLC to a newly formed corporation or just checks the box on the LLC to become a corporation. After this series of steps, the stock of the new C corporation that is owned by Holdco may qualify as QSBS, providing the requirements of Section 1202 are met.
This structure preserves the operating entity’s employer identification number (EIN), contracts, licenses, employee arrangements and other business relationships while creating a more flexible platform for later planning.
A more aggressive alternative is to liquidate the S corporation and have the shareholders contribute the business assets to a newly formed C corporation.
This approach has major disadvantages, the first of which is that the liquidation is taxable. Depending on the assets involved, the transaction may trigger corporate-level gain, shareholder-level gain, and even ordinary income through depreciation recapture. In addition, the IRS can challenge the plan under the liquidation-reincorporation doctrine. For these reasons, few shareholders consider the liquidation scenario.
For companies with multiple business lines or valuable non-operating assets, a tax-free divisive transaction under Section 355 may create planning opportunities.
In broad terms, a corporation (Distributing) could separate assets through a spin-off or other divisive restructuring where one of two or more businesses with a five-year operating history is transferred to a subsidiary (Controlled) that is then distributed to shareholders in a tax-free transaction. This strategy generally requires shareholders to hold at least 50% of both entities (Distributing and Controlled) for at least two years following the distribution to avoid causing the distribution to be taxable under Section 355(e).
While this alternative may provide flexibility in certain fact patterns, it is among the most technically demanding restructuring strategies in the tax law. The requirements are extensive, and the costs of implementation can be substantial. As a result, it is generally reserved for situations where one or more shareholders plan to claim a large Section 1202 exclusion under the 10-times-basis rule.
The biggest mistake founders make is waiting until a buyer appears. By then, many of the most effective QSBS strategies are no longer available.
The key takeaway is simple: a business that began life as an S corporation can still position itself to benefit from Section 1202, but doing so typically requires creating newly issued stock in a qualifying C corporation. The optimal approach depends on the company’s value, asset profile, and exit horizon.
For founders expecting significant future growth, the discussion should occur years before a sale — not months before signing a letter of intent. With careful planning, an S corporation’s history does not necessarily prevent a future QSBS opportunity, but it does require a thoughtful restructuring strategy to get there.
