If you formed as an S corporation, your shares will never be qualified small business stock. Section 1202(c)(1) requires stock in a C corporation, and shares issued while the corporation was an S corporation do not qualify. Revoking the S election does not fix it either, because there is no new stock issued for Section 1202 to attach to. I have written before about why only C corporations can issue QSBS.
Plenty of owners find this out years in, after the business has become valuable. The question is whether anything can still be done.
Something can. There are two routes, and which one fits depends mostly on what the business is worth today.
Route one: wind up the S corporation and start clean
This is the option if you are early and the business is worth very little.
Liquidate the S corporation, distribute the assets to the shareholders, and have the shareholders contribute those assets to a newly formed C corporation in exchange for stock. The S corporation goes away. You own the C corporation directly.
Owning the stock directly is the real advantage. You are not relying on the Section 1202(g) pass-through rules to get the exclusion to you, you avoid the problems that come with an S corporation holding C corporation stock, and you are in a far better position if you ever want to gift shares to trusts — there is no provision letting a transferee of gifted S corporation stock share in the exclusion.
The catch is that the liquidation is taxable. The S corporation is treated as selling its assets at fair market value, and that gain passes through to you now. When the business is worth almost nothing, that tax is almost nothing. When it is worth real money, this route stops making sense quickly.
Two other things to weigh. A true liquidation means actually assigning contracts, licenses, and permits, and it can expose the owners to the business's obligations along the way. And winding up a business only to reincorporate the same business with the same owners invites an argument that the two steps should be collapsed. This is not something to do casually or on a compressed timeline.
Route two: keep the S corporation and put a C corporation underneath it
This is the option once the business has real value.
The S corporation contributes its business to a newly formed C corporation in a Section 351 exchange and takes back stock. The S corporation survives as the parent; the new C corporation becomes its subsidiary and runs the business. That subsidiary's stock can qualify as QSBS from the day it is issued, and Section 1202(g) passes the eventual exclusion through to you as a shareholder.
Nothing is taxed on the way in. That is the whole reason this route exists for an established business, and it is why almost everyone past the earliest stage ends up here.
There are a few ways to build it, and the right one depends on what needs to stay where — often the original operating entity is preserved rather than moved, so contracts and licenses never have to be reassigned. They all end in the same structure: S corporation on top, C corporation underneath.
The form matters, and there is a case on it. In Leto v. United States, an Arizona LLC taxed as an S corporation merged into a newly formed Delaware C corporation, and the members received C corporation stock in exchange for their LLC interests. A federal district court held the stock failed Section 1202's original issuance requirement: because the LLC interests were stock for federal tax purposes, the exchange was stock for stock, and Section 1202(c)(1)(B) excludes stock acquired in exchange for other stock. The decision came on the government's motion for judgment on the pleadings and the case later settled, so it is not the last word. But the lesson is clear enough. Had the entity instead contributed its assets to the new corporation in exchange for stock, the analysis would have come out differently.
Scott Dolson at FBT Gibbons, formerly Frost Brown Todd, has written the most thorough treatment of the structuring options in Advanced Section 1202 (QSBS) Planning for S Corporations. If you want the full mechanics, start there.
What either route gets you, and what neither does
Both move future appreciation into a QSBS-eligible vehicle. Everything the business grows to be worth from that date forward can qualify for the exclusion.
Neither does anything for the value you have already built. Section 1202(i)(1)(B) sets your basis in the new stock at the fair market value of what you contributed, which takes that value out of eligible gain. Whatever the business is worth on the day you do this stays taxable when you sell.
This is the settled reading rather than an aggressive one, and it is worth seeing stated more than once. WilmerHale describes the fair market value basis rule as designed to prevent holders from using Section 1202 to exclude pre-contribution gain, with the consequence that previously unrecognized gain is taxed in full on a later sale and only subsequent appreciation counts as eligible gain. Smith Anderson puts it the same way: the rules limit the gain eligible for exclusion to gains accruing after the property is transferred to the corporation. Dolson works the arithmetic — property with a tax basis of zero and a Section 1202 basis of $10 million, sold later for $80 million, produces $10 million of recognized gain and a potential $70 million exclusion.
I walk through the numbers in more detail in How to Get $750 Million Out of a Single Company Tax-Free.
The holding period also starts at the contribution, not when you started the business. Under Section 1202(i)(1)(A), the stock is treated as acquired on the date of the exchange.
So this is a forward instrument. It is worth the most to owners who believe the business has substantial growth ahead of it, and the least to owners who are close to selling.
When it is too late for either route
The business is already worth most of what you expect to sell it for. The exclusion reaches only growth after the contribution. Contribute a business worth $50 million and sell for $75 million, and you exclude $25 million. What stays taxable is the built-in gain in what you contributed — its fair market value at contribution, less your basis in those assets at that time. This earns its cost when there is real growth still ahead.
You are planning to sell in the next two or three years. The exclusion does not start until year three. For stock issued after July 4, 2025, you exclude 50% of gain at three years, 75% at four, and 100% at five. Sell before three years and this bought you nothing at all.
You have a signed letter of intent. There is no version of this that shelters gain on a sale already in motion.
The business is worth more than $75 million. Section 1202(d) caps aggregate gross assets immediately after issuance at $75 million for stock issued after July 4, 2025, measured at fair market value for contributed property. Above that, the stock is not QSBS at all.
What to work through before you do it
Real restructurings have moving parts. The ones that come up most:
- An appraisal of the business you are contributing. Its fair market value at contribution sets your basis for Section 1202 purposes, which determines both how much of your eventual gain is excludable and whether you clear the $75 million ceiling. Dolson's guidance is to obtain an independent appraisal, and this is not a number to leave until exit.
- Whether your state follows the federal exclusion. Several do not — see the state-by-state conformity guide.
- On route two, distributions out of the C corporation subsidiary, which can become passive investment income to the S corporation parent and put the S election at risk.
- A non-tax business reason for the restructuring, documented at the time.
- State transfer and gross receipts taxes, which do not follow federal nonrecognition.
None of these are reasons not to do it. They are reasons to do it deliberately.
