founder who forms a C-corporation, holds the stock for five years, and keeps the company inside the § 1202 guardrails can walk away from a sale owing zero federal tax on up to $10 million of gain. That is the deal Congress wrote into IRC § 1202, and as of 2018 it is the single most valuable piece of paper planning a founder can do.
This guide is about planning for QSBS eligibility from the formation papers forward, because the rules are unforgiving and almost every disqualifier happens before the company has revenue.
The five requirements, stated plainly
Qualified Small Business Stock is a creature of IRC § 1202. The statute sets five conditions, and every one of them has to hold continuously or at the moment the statute specifies. A miss on any single one disqualifies the stock.
The issuer has to be a domestic C-corporation. § 1202(c)(1) is explicit. An LLC does not qualify, and neither does an S-corporation. If you plan to rely on § 1202, you incorporate as a C-corp from the start. Converting an LLC to a C-corp later does not cure the pre-conversion period; the holding-period clock starts only when the C-corp issues stock for the member's interests.
The corporation has to pass a gross-assets test. Under § 1202(d), at all times from August 10, 1993 through the moment immediately after the stock is issued, the corporation's aggregate gross assets cannot exceed $50 million. "Gross assets" means cash plus the adjusted basis of other property, with contributed property measured at its fair market value on the contribution date rather than basis. The test is measured at issuance; you can blow through $50 million later and the stock already issued stays qualified. But you cannot issue new QSBS once you have crossed the line. For a company raising a Series B that will push gross assets past $50 million, the Series B round itself may be the last round eligible for QSBS treatment, and only if the closing balance sheet immediately after the closing stays under.
The corporation has to satisfy the active-business requirement. Under § 1202(c)(2) and (e), during substantially all of the taxpayer's holding period, at least 80% of the value of the corporation's assets has to be used in the active conduct of one or more qualified trades or businesses. Cash counts as an active-business asset for the first two years after receipt, and thereafter only if it is reasonably required working capital. Investment securities generally do not. A startup sitting on $40 million of Series B proceeds in a money-market fund three years after the raise is a candidate for failing the 80% test.
The shareholder has to have acquired the stock at original issuance, directly from the corporation, in exchange for money, property (other than stock), or services. § 1202(c)(1)(B). Secondary-market stock does not qualify. Stock bought from a departing founder does not qualify. Stock received in a tax-free reorganization can carry QSBS status forward under § 1202(h), but the planning answer for a new issuance is always to issue new stock from the company rather than transfer old stock.
The shareholder has to hold the stock for more than five years. § 1202(b)(2). The holding period runs from the date of issuance. Options and warrants start their clock on exercise, not on grant. Restricted stock under a § 83(b) election starts its clock on grant; restricted stock without a § 83(b) election starts its clock on vesting. This is the single most common planning error. A founder who takes restricted stock on day one and forgets to file the § 83(b) within 30 days has just pushed the QSBS clock to the far end of the vesting schedule.
What a "qualified trade or business" actually excludes
§ 1202(e)(3) lists the businesses Congress decided were not the kind of small business it wanted to subsidize. The list is narrower than founders usually assume, and broader than founders usually hope.
Excluded: any trade or business involving the performance of services in the fields of health, law, engineering, architecture, accounting, actuarial science, performing arts, consulting, athletics, financial services, or brokerage services. Any business whose principal asset is the reputation or skill of one or more employees. Banking, insurance, financing, leasing, investing, or similar businesses. Farming (including the raising or harvesting of trees). Any business involving the production or extraction of products of a character for which percentage depletion is allowed (oil, gas, minerals). Hotels, motels, restaurants, or similar businesses.
The consulting and financial-services exclusions catch a lot of what founders pitch as a software business. A firm that bills hourly for advisory work, even with a software product on the side, risks being characterized by its principal service. A fintech that holds customer deposits or earns fee income on managed assets can look like a financial- services business under the statute. The operational question is where enterprise value comes from. If the answer is "our people's advice," § 1202(e)(3) is probably in the way.
The classic safe harbor is a product company that sells software, hardware, or a consumer good. Manufacturing is in. SaaS, in the ordinary case, is in. Most device and biotech companies are in, provided they are not structured as professional service firms. Health-tech sits on a fault line: a software company that sells to hospitals is usually fine; a telemedicine company whose product is the clinicians themselves is usually out.
The exclusion percentages and the cap
§ 1202(a) sets the exclusion percentage by reference to when the stock was acquired. Stock acquired before February 18, 2009 gets the original 50% exclusion. Stock acquired after February 17, 2009 and on or before September 27, 2010 gets 75%. Stock acquired after September 27, 2010 gets 100%.
The Protecting Americans from Tax Hikes Act of 2015 (P.L. 114-113) made the 100% exclusion permanent. Before PATH, the rate had been extended year to year and was a perennial source of end-of-year uncertainty. As of 2018, a founder who forms a qualifying C-corp this week and sells in five years gets the 100% rate as a matter of permanent law.
The cap is at § 1202(b)(1). The gain a taxpayer can exclude in any tax year, with respect to any one issuer, is capped at the greater of $10 million (reduced by prior excluded gain from that issuer) or ten times the taxpayer's aggregate adjusted basis in the QSBS of that issuer disposed of in the year. The cap is per issuer, per taxpayer. Married filing jointly is one taxpayer, not two. Trusts and family limited partnerships are sometimes used to multiply the cap across related taxpayers (QSBS stacking), and the IRS has not issued comprehensive guidance on the outside limits.
The planning order at formation
The planning is almost entirely about day-one and first-year decisions. Here is the order that actually works.
Incorporate as a Delaware C-corporation. The state choice is not a § 1202 requirement; any state will do. Delaware is the default because the rest of the capital stack assumes it. If the business is an operating LLC today, incorporate a new C-corp and either convert the LLC by statutory conversion or contribute the LLC interests in a § 351 exchange. Either path starts a new QSBS holding period on the issue date. For the state- level filing mechanics, see our Delaware formation guide.
Issue founder stock on day one. Issue the full number of shares the founders expect to own, at a nominal price, before any priced round. Price matters here: the cheaper the stock and the earlier the issuance, the longer the five-year clock has been running when the big exit happens, and the more likely the 10x-basis prong of the cap is moot. A founder who pays $0.0001 per share for 5 million shares has a total basis of $500, which makes the $10 million prong the governing cap in any realistic exit.
File the § 83(b) election within 30 days of issuance if the stock is subject to vesting. This tells the IRS to treat the stock as fully transferred on the issue date. Without the election, the QSBS clock restarts on each vesting event. The 30 days cannot be extended.
Watch the gross-assets line at every financing. Model the post-closing balance sheet against the $50 million ceiling before the round closes. If the round would push the company over, consider whether the founders and early employees want to issue additional QSBS to themselves (via bonus stock, option exercises, or a dividend of rights) in the same closing, before the new cash lands. This is unglamorous, and it is the single most valuable planning move for a company that knows its next round will cross the line.
Keep a written active-business narrative. If the company holds material cash or non-operating assets, have the CFO or outside accountant document, at each year-end, why those assets are reasonably required for the active business. This is the record the company will want if § 1202(e) ever gets audited.
The § 1045 rollover, and the secondary holder problem
§ 1045 is the sibling statute. If a taxpayer holds QSBS for more than six months and sells before the five-year clock runs, the taxpayer can roll the gain into other QSBS acquired within 60 days of the sale and tack the old holding period onto the new stock. The election is made on the return for the year of sale. It is the mechanic that lets a founder who sells Company A at year four buy into Company B and keep QSBS status alive.
The rollover is also a trap. The replacement stock has to be QSBS itself, which means the replacement issuer has to satisfy every § 1202 requirement at the time of the replacement issuance. A taxpayer who rolls into a company that turns out to be in an excluded trade or business, or that was already over the $50 million gross-assets line, gets no rollover and no QSBS on the new stock.
And the secondary-holder problem: a taxpayer who buys founder stock from a departing founder does not inherit QSBS status. The original-issuance requirement at § 1202(c)(1)(B) is hard. This is why early employees who buy founder stock on a secondary basis are usually worse off than early employees who exercise options and receive newly issued shares.
TCJA and the interaction with the 21% rate
The Tax Cuts and Jobs Act (P.L. 115-97), signed December 22, 2017, cut the corporate rate to a flat 21% effective for tax years beginning after December 31, 2017 and repealed the corporate AMT. Before TCJA, the case for an early-stage C-corp over an LLC taxed as a partnership was narrower: the C-corp paid 35% at the entity level and the shareholders paid again on dividends, while partners in an LLC paid once at their individual marginal rate. QSBS was the counterweight that made the C-corp structure worth the double layer for founders who planned to exit.
At 21% plus 100% QSBS on exit, the arithmetic tips decisively for any founder who expects the enterprise to exit rather than distribute cash. A founder who holds for five years and clears the § 1202 gates faces a combined federal effective rate near zero on the first $10 million of gain per holder. For the non-QSBS portion, the long-term capital gains rate tops out at 20% plus the 3.8% net investment income tax under § 1411, and 23.8% is still lower than the 37% top individual rate that would apply to pass-through operating income.
The counter-cases are real. A business that will distribute operating cash flow to owners rather than reinvest, or one in an excluded trade under § 1202(e)(3), or one that will stay small and never sell, is usually worse off in a C-corp than in a pass-through. The § 199A deduction, enacted by TCJA and effective for 2018 forward, gives owners of qualifying non-service businesses a 20% deduction on qualified business income and strengthens the pass-through case.
The traps worth naming
Five things dispose of QSBS most often, in order of frequency.
Redemptions. Under § 1202(c)(3), a corporation that redeems stock from the taxpayer (or a related party) within four years of the QSBS issuance, or redeems more than 5% of the aggregate value of its stock within one year before the issuance, can taint the QSBS. Founder buybacks, even at nominal amounts, are the quiet killer. A company that bought back a co-founder's shares last year and is now issuing new shares to a replacement founder has a § 1202(c)(3) problem on the new shares.
Conversions from LLC without care. The § 351 contribution of LLC interests to a newco C-corp works, but the mechanics have to be clean. Basis in the contributed interests carries over. The five-year clock starts on the C-corp stock issuance.
Cash on the balance sheet. The active-business test does not care that the company "will" deploy the cash; it cares whether the cash is reasonably required for the business as of the measurement. Sitting on a war chest for acquisitions is defensible; sitting on it because the board has not decided is less so.
Professional-services framing. Companies that pitch themselves as "the consulting firm for X" or "the law firm of the future" may be QSBS- disqualified out of the gate. The statutory language is about the trade or business, not about the marketing. The fix, where possible, is to make sure the enterprise value sits in a product, a dataset, or a platform rather than in the hours of named people.
Cap confusion. The $10 million prong is per issuer per taxpayer, and married-filing-jointly is one taxpayer. Trusts can multiply the cap in some configurations, but the planning is fact-specific and needs a tax lawyer rather than a founder's hunch.
A rule of thumb
If the company is a product business, plans to exit rather than distribute, and can be formed as a C-corp from day one, set up for QSBS now and file the § 83(b) within 30 days. The five-year clock is the most valuable thing on your founding to-do list.
