QSBS: A Quick Overview
Qualified Small Business Stock (QSBS) is a tax benefit that can make angel investing even more attractive. Under Section 1202 of the Internal Revenue Code, if you invest in the right kind of startup and hold long enough, you may be able to exclude up to 100% of your gains from federal taxes when you sell your shares. That’s not a typo. The potential tax savings can be enormous, and they’re designed to reward investors willing to take risks on early-stage companies.
Two Schedules, Split by July 4, 2025
The One Big Beautiful Bill Act rewrote Section 1202 on July 4, 2025, and the date you acquired your stock decides which set of rules you live under. This is the single most important thing to understand about QSBS today, because a portfolio can hold two positions in the same company running on two different schedules.
Stock acquired after July 4, 2025 earns a tiered exclusion:
- 3 years: 50% of the gain excluded
- 4 years: 75% excluded
- 5 years: 100% excluded
The cap is the greater of $15 million or 10x your basis, and the company-side gross-assets ceiling rose to $75 million.
Stock acquired on or before July 4, 2025 keeps the older all-or-nothing rule: nothing at all until you pass five years, then 100%, capped at the greater of $10 million or 10x basis, against a $50 million gross-assets ceiling.
Note that the tiers are cliffs, not an accrual. A lot on the new schedule is worth 0% at two years and eleven months and 50% a month later. There is no partial credit for partial time.
What Still Has to Be True
The tiers only matter if the stock qualifies in the first place, and those rules didn’t loosen:
- The stock must be issued by a U.S. C corporation (not an LLC or S corp).
- The company’s gross assets must be under the ceiling at the time of issuance — $75M for stock issued after July 4, 2025, $50M before.
- You must acquire the shares directly from the company, not from another investor.
- The company must be an active business (not an investment holding company, for example).
One subtlety worth internalizing: the holding period starts the day after you acquire the stock, so the earliest qualifying sale is one day past the anniversary. That is exactly the kind of detail worth tracking rather than eyeballing.
Federal vs. State Tax Treatment
At the federal level the rules are relatively clear and generous. But it’s not all champagne and confetti: state tax treatment of QSBS varies. Many states follow the federal exclusion, but some — like California — do not recognize it. That means if you’re a California resident, you’ll still owe California state taxes on your gains even if you’re fully exempt federally. Other states, such as New Jersey and Pennsylvania, also do not conform. Always check your specific state’s tax code or consult a tax professional before celebrating those potential windfalls.
SAFEs and QSBS: A Complication
SAFEs (Simple Agreements for Future Equity) are a popular way for startups to raise early capital. But when it comes to QSBS, SAFEs add a wrinkle: because a SAFE is not stock, the QSBS holding period generally doesn’t begin until the SAFE converts into actual shares. That conversion date also decides which schedule you land on — a SAFE signed in 2024 that converts in 2026 is new stock on the tiered schedule, not old stock on the five-year one.
Eligibility also depends on the company’s gross assets at the time the stock is issued, not when the SAFE was purchased, so a later conversion could jeopardize eligibility if the company has grown past the ceiling. Importantly, gross assets are not the same as valuation: a company can be valued well above $75M and still qualify if its actual assets remain below the limit, though large financings can push it over. If you’re investing via a SAFE and aiming for QSBS treatment, track conversion timing and company growth carefully — which Signed can help with, naturally — and consult your tax advisor. The company itself is a good resource too; they can often tell you plainly whether your shares qualify.
Making the Most of QSBS
QSBS can be a powerful incentive for angel investors, but it comes with fine print, and since 2025 that fine print depends on a date. Track your acquisition dates carefully, note the types of shares you receive, and keep an eye on both federal and state treatment.
If you’re serious about angel investing, understanding QSBS could help you keep a great deal more of your gains — just make sure you’re working with a good tax advisor to navigate the details. This is general information, not tax advice.
