Yes — Florida founders get the full federal Section 1202 QSBS exclusion of up to $10 million (or $15 million for stock issued after July 4, 2025), and Florida adds 0% state tax on top. That's the short answer. The longer answer is more interesting.
QSBS confuses founders because it sounds like a state-level benefit and it isn't. The exclusion lives in the federal tax code, so a founder in Miami and a founder in Manhattan claim the exact same $10–15 million break. What makes Florida special isn't the exclusion — it's what happens to every dollar of gain above the cap, and what your state takes on the way out. In Florida, the state takes nothing.
Florida QSBS and Section 1202 in 2026: What Founders Actually Get
Florida founders qualify for the federal Section 1202 QSBS exclusion in 2026 on the same terms as founders anywhere in the US: original-issue C-corporation stock held more than five years can have up to $10 million of gain — or $15 million for stock acquired after July 4, 2025 — excluded from federal capital gains tax, capped at the greater of that amount or 10 times basis. Because Florida levies no state income tax, the entire qualifying gain can be tax-free.
Section 1202 was enacted in 1993 and made permanently 100%-exclusionary for stock acquired after September 27, 2010. The mechanics are federal and identical coast to coast. The variable that swings six and seven figures is your state of residence at the time of sale — which is exactly where Florida wins. You can model the federal-and-state stack alongside other founder tax scenarios in our QSBS dashboard.
Section 1202 Eligibility: The Five Tests Every Florida Founder Must Pass
QSBS is not automatic. The stock has to clear all five of these tests, and missing any one of them disqualifies the gain entirely:
C-corporation only
The issuer must be a domestic C-corp at issuance and substantially through the holding period. LLCs and S-corps do not qualify — this is the single most common disqualifier for early founders who started as an LLC.
Original issuance
You must acquire the stock directly from the company for cash, property, or services — not on the secondary market. Founder shares and priced-round investments qualify; buying someone else's shares does not.
Five-year holding period
Hold more than five years for the full 100% exclusion. Stock acquired after July 4, 2025 unlocks a partial exclusion earlier: 50% at three years and 75% at four years under the OBBBA.
$75M gross-asset test
The company's gross assets must have been $75 million or less (raised from $50 million by the OBBBA) at and immediately after the stock was issued. Later growth past $75M does not retroactively disqualify earlier shares.
Active qualified business
At least 80% of assets must be used in an active trade. Excluded sectors include finance, professional services, hospitality, farming, and mining — most software and product startups qualify.
Florida QSBS vs Other States: What a $50M Exit Actually Costs
Here is the comparison that matters. Take a founder with near-zero basis selling QSBS-eligible stock for $50 million after a 5-year hold. The first $10 million is federally excluded everywhere. The remaining $40 million faces the federal long-term capital gains rate of 20% plus the 3.8% net investment income tax — about $9.52 million — in every state. The difference is entirely the state layer, and whether that state even honors the federal exclusion.
| State | Conforms to §1202? | Top state cap-gains rate | Est. state tax on $50M exit | Total tax (fed + state) |
|---|---|---|---|---|
| Florida | N/A — no income tax | 0% | $0 | ~$9.5M |
| Texas | N/A — no income tax | 0% | $0 | ~$9.5M |
| Washington | N/A — no income tax | 7% (gains over ~$270K) | ~$2.8M | ~$12.3M |
| New York | Yes — excludes $10M | 10.9% | ~$4.4M | ~$13.9M |
| New Jersey | No — taxes full gain | 10.75% | ~$5.4M | ~$14.9M |
| California | No — taxes full gain | 13.3% | ~$6.65M | ~$16.2M |
| Massachusetts | Partial conformity | 5% (+4% over $1M) | ~$3.6M | ~$13.1M |
Illustrative estimates for a founder with near-zero basis, $50M sale, 5-year hold, $10M federal exclusion. Federal layer assumes 20% LTCG + 3.8% NIIT. State figures are approximate and ignore deductions, AMT interactions, and the 7% federal AMT preference add-back on the excluded portion. Not tax advice.
The spread is roughly $6.7 million between Florida and California on the same exit. That is not a rounding error — it is a second seed round's worth of capital that stays with the founder.
Why Florida QSBS Beats California: Conformity Is the Hidden Trap
There are two separate questions stacked on top of each other, and founders routinely conflate them. The first: does your state conform to Section 1202 — meaning, does it honor the federal exclusion at the state level? The second: what is your state's capital gains rate on whatever isn't excluded? Florida sidesteps both because it has no income tax at all.
California is the cautionary tale. It does not conform to Section 1202 — it repealed its state-level QSBS benefit back in 2013 — so a California founder owes 13.3% state tax on the entire gain, including the portion the IRS excludes. New Jersey and Pennsylvania similarly tax the full gain. New York and most income-tax states do conform, so they at least mirror the $10 million federal exclusion, but still tax everything above it. Florida residents never enter this maze: there is no state return on which a capital gain could appear.
This is why South Florida has pulled in founders and funds since 2020 — the QSBS-plus-no-state-tax stack is simply the most efficient in the country. If you're weighing the move, our Florida vs New York tax breakdown runs the full founder math.
The 2025 OBBBA Changes: Bigger Caps and Earlier Exclusions
The One Big Beautiful Bill Act, signed July 4, 2025, made QSBS materially more generous for stock acquired after that date — and Florida founders capture all of it. Three changes matter:
- → Tiered holding periods. The old rule was all-or-nothing at five years. Now newly issued stock gets a 50% exclusion at three years, 75% at four years, and 100% at five — a real benefit for founders facing an earlier acquisition.
- → Cap raised to $15M. The per-issuer gain cap rose from $10 million to $15 million for post–July 4, 2025 stock, and it indexes to inflation beginning in 2027.
- → Gross-asset ceiling raised to $75M. The company can now have up to $75 million in gross assets (up from $50 million) at issuance and still issue qualifying QSBS, expanding eligibility to later-stage rounds.
Stock acquired before July 5, 2025 keeps the legacy rules — five-year hold, 100% exclusion, $10 million cap, $50 million asset test. Many founders will hold both vintages and should track them separately, because the exclusion is calculated per issuer and per acquisition tranche.
How Florida Founders Maximize Section 1202 in 2026
The exclusion is generous but easy to forfeit. A few practical moves separate founders who keep the full break from those who lose it on a technicality:
- → Incorporate as a C-corp early. The five-year clock starts at issuance, and LLC/S-corp years don't count. Converting an LLC to a C-corp resets the basis and the clock — do it before you have meaningful value.
- → Document gross assets at issuance. Keep a dated record showing the company was under the $75 million ($50 million pre-OBBBA) threshold when each tranche of stock was issued. The IRS puts the burden of proof on the taxpayer.
- → Consider QSBS "stacking" and "packing." Gifting shares to non-grantor trusts or family members can multiply the $10–15 million cap across multiple taxpayers, and converting at higher basis can lift the 10x-basis ceiling above the flat cap.
- → Establish Florida residency well before the sale. Residency is determined at the time of sale. Move, get a Florida driver's license, register to vote, and spend the days — high-tax states audit part-year moves aggressively.
