For most small business owners, the QSBS exclusion doesn't apply, because it covers only C-corporation stock bought directly from the company, and Apollon Wealth Management checks those two facts before a sale plan relies on it. Rule of thumb: QSBS deserves an hour with your CPA only if three answers are yes. The company was a C corporation when your shares were issued, you got the shares from the company itself (or by gift or inheritance from someone who did) after August 10, 1993, and the business isn't in an excluded field such as health, law, accounting, consulting or financial services. The ordinary moment this comes up isn't a tax seminar. It's an owner sitting with a letter of intent from his employees, wondering whether to sign it himself or give some shares to his kids first. These are the kinds of questions we hear in first meetings, and they usually come down to paperwork from decades ago, not anything that happens at the closing table.

We ask for the stock ledger before we ask anything else, because the issue date on each block decides this whole question, not the company's current tax return.
CPA and Tax Director
A gift made after the letter of intent is signed is the single most expensive sequencing mistake we see with QSBS, because it can undo the exclusion entirely.

If an owner is seriously ill, we usually lean toward holding the shares for the stepped-up basis rather than gifting them, because death resets the tax cost to zero on the built-in gain.

Step 1: Check what the company was on the day your shares were issued
Pull the articles of incorporation, the stock ledger and the corporate return filed for each year a block of shares was issued. Form 1120 means a C corporation. Form 1120-S means an S corporation. Only stock issued while the business was a domestic C corporation can ever be QSBS.
Stock issued during the S corporation years never turns into QSBS, even after the business converts to a C corporation. Only shares issued after the conversion date can count.
An owner sees 'C corporation' on this year's return and assumes every share he holds qualifies. That's the slip. Apollon Wealth Management advisors date each block of stock separately, because one company can hold qualifying and non-qualifying shares side by side.
Pulling the right documents
Why one company can have two answers
Step 2: Trace how each block of shares reached you
Shares bought from another shareholder, such as a retiring partner or a sibling cashing out, are not QSBS. The rule requires original issue from the corporation itself, in exchange for money, property or services.
Shares received by gift or inheritance keep the QSBS status and the holding period of the person who gave them. You'll want the gift letter or Form 709, or the estate inventory, plus proof of the giver's original purchase, like a cancelled check or board minutes authorizing the issue.
A shop a father started often carries two blocks: his original shares, and shares the owner bought later when the company raised money. List them on one page, with a date, source and basis for each.
Step 3: Test the business, not just the shares
At least 80 percent of the company's assets have to be used in an active qualified business during substantially all of the holding period. A machine shop or manufacturer usually passes this test. A company that also owns its building and leases out half of it may not.
Excluded fields include health, law, engineering and architecture, accounting, actuarial work, consulting, financial services, farming, hotels and restaurants. A machine shop that sells parts is manufacturing. One that mostly sells design work needs a CPA to look closer.
The company's gross assets also had to sit under a dollar ceiling at the moment the shares were issued. Congress has adjusted that ceiling for newer stock, so check the current IRS limit and pull the balance sheet from the issue date itself.
The 80 percent active business test
Fields the exclusion doesn't reach
How long must the shares be held, and which dates count?
The dates run in calendar order: the issue date (after August 10, 1993), the fifth anniversary of that date, the gift date if there is one, the letter of intent, the closing date, and the sale-year return, where the exclusion is reported on Form 8949 with code Q.
A gift above the $19,000 annual exclusion per recipient (2026) needs Form 709 by April 15 of the following year. Gift tax itself usually isn't due until lifetime gifts exceed the $15,000,000 exclusion.
Two timing errors cost the most. One is selling a month before the fifth anniversary and losing the exclusion entirely. The other is gifting shares once the buyer's signed letter of intent is on the table, which lets the IRS treat the sale as the giver's own, not the recipient's. At Apollon Wealth Management, the decisions run in a short list by deadline, and the gift date goes on that list ahead of any signature on deal terms.
Dates in order
Where owners get the sequence backward
The gift has to happen before the letter of intent is signed. Afterward, the IRS can treat the sale as yours, not your child's, and the exclusion disappears.
Step 4: Run the numbers for yourself and for the person who inherits the shares
Merle (hypothetical) is 68 and widowed, and owns the machine shop his father started, worth about $2.5 million. He holds two blocks of stock. The first is 60 percent, inherited from his father, issued before August 10, 1993, with a $500,000 basis. The second is 40 percent he bought directly from the company more than five years ago for $200,000. At a $2.5 million sale price, the old block is worth $1.5 million, a $1 million gain, and the newer block is worth $1 million, an $800,000 gain.
Say the newer block passes every QSBS test, and Merle gives it to his two daughters before any deal is negotiated. They keep his basis and his holding period, so their combined $800,000 gain can be excluded. If he gave them the old block instead, they'd owe capital gains tax on the full $1 million. If he keeps the old block until he dies, it gets a stepped-up basis and that gain disappears altogether.
The table below compares three sale prices on the same two blocks: the QSBS gain grows with the price, but its share of total gain slips from about 46 percent to about 43 percent, because the inherited block's gain grows faster as the price rises.
Three options, same criteria of Merle's cash, his daughters' tax cost, and who controls the shop. Option A: Merle sells both blocks himself, excludes the $800,000 and pays capital gains tax on $1 million. Option B: he gives the QSBS block to his daughters, 20 percent each, before any letter of intent, and they sell it with the exclusion. Option C: same gift, but he keeps the inherited block until death for the stepped-up basis. Option C leaves him with the least cash while he's alive. For a 68-year-old who wants the deal done while he's healthy, we'd lean toward Option B.
There's a Medicare angle too. Excluded QSBS gain stays out of adjusted gross income, so it doesn't count toward IRMAA. The $1 million taxable gain does. For a single filer, under 2026 figures, that can push the Part B premium from $202.90 to $689.90 per month two years later. Merle also needs to keep the sale year clear of his first required minimum distribution at 73. A household running this math themselves can use our calculator to see how the excluded share shifts at different sale prices.
Merle's two blocks
Three ways to handle the sale
| Shop sale price | Gain on QSBS block | Gain on inherited block | Gain that could be excluded |
|---|---|---|---|
| $2,000,000 | $600,000 | $700,000 | $600,000 |
| $2,500,000 | $800,000 | $1,000,000 | $800,000 |
| $3,000,000 | $1,000,000 | $1,300,000 | $1,000,000 |
Step 5: Keep the shares titled in your own name until the deal closes
Retitling QSBS shares into a family LLC taxed as a partnership, often done by an estate attorney for convenience, can strip the QSBS status. Contributions to a partnership aren't among the transfers that carry the exclusion over. Moving the shares back out afterward doesn't reliably restore it. On Merle's numbers, that mistake puts the full $800,000 gain back on the tax return, so the fix is simple: stop the transfer before anyone signs anything.
How much the sale price, a spouse and the buyer's terms change the result
Below the dollar cap, the cap doesn't matter at all. Above it, the exclusion is limited to the greater of the cap (check the current IRS limit) or ten times the shareholder's basis. Each recipient of a gift gets a separate cap, which is why owners of larger companies spread gifts across several children.
A widowed owner like Merle files alone. A married owner should ask a CPA how the cap applies on a joint return. At death, shares get a stepped-up basis and the heir keeps QSBS status, so a very sick owner may gain little from gifting low-basis shares now rather than waiting.
QSBS applies only when shareholders sell stock. If the employees' lender insists on buying the shop's assets instead, the exclusion is lost outright. Apollon Wealth Management clients put 'stock sale' in the first draft of deal terms for this reason.
Congress has changed QSBS rules before and can again, and the employees' financing can shrink the final price too. Plan the gift and the spending so the plan still holds up if the exclusion disappears. Returns on sale proceeds are never certain, and invested money can lose value.

Spouse, timing and the buyer's deal structure
Before the buyer's draft arrives, the QSBS question for Apollon Wealth Management
Bring one question to the first conversation: which of my share blocks can be shown, on paper, to be original-issue C-corporation stock held long enough, and should those go to my children before a letter of intent? Bring the stock ledger and the issue-year tax return, and nothing more.
The gift has to happen before the letter of intent, not after it, or the exclusion can disappear with it.
Your questions about qsbs exclusion small business, answered
Is the QSBS exclusion real money for a $2.5 million machine shop, or is it only a tax break for tech startups?
It applies to any qualifying C corporation, not just startups. In Merle's hypothetical case, $800,000 of gain on a $2.5 million machine shop could be excluded, the same rule a software founder would use.
If Dad gives me his shares a few months before the employees buy the shop, do I still get the QSBS exclusion?
Usually yes, as long as the gift happens before any letter of intent is signed and the shares already passed every QSBS test. Gift after the letter of intent is signed, and the IRS can treat the sale as your father's, not yours.
