QSBS in Florida: No State Income Tax, Healthcare and Fintech Industry Traps, and the California Residency Issue

Florida and Section 1202: the simple answer

Florida imposes no personal income tax and no state capital gains tax.¹ Florida's Constitution (Article VII, Section 5) restricts income taxation to corporations and requires a 60% supermajority of voters to impose any income tax on individuals. This is not merely legislative policy — it requires a constitutional amendment approved at the ballot. Florida's no-income-tax status is therefore structurally more durable than a state like Washington, where the capital gains tax was enacted by statute and has already faced legislative repeal efforts.

Because Florida has no income tax, it has no position on Section 1202 conformity. There is no Florida statute or ruling that says "Florida conforms to §1202" or "Florida does not conform" — the concept is simply inapplicable. When a Florida-resident founder sells QSBS stock and claims the federal exclusion, the state tax column is $0 regardless of whether the exclusion applies, how large it is, or when the stock was issued. The entire QSBS analysis is federal.

For Florida founders, QSBS planning focuses entirely on the eight federal §1202 qualification tests. If those tests are passed, the state tax problem does not exist. But for Florida founders specifically, there is one federal qualification test that deserves special attention given Florida's startup ecosystem: the excluded-industries rule under §1202(e)(3).

The excluded-industries trap: healthcare, biotech, and fintech founders

Section 1202(e)(3) excludes from QSBS qualification any business "in the fields of health, law, engineering, architecture, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, or any trade or business where the principal asset of such trade or business is the reputation or skill of one or more of its employees."² Section 1202(e)(3)(B) separately excludes banking, insurance, financing, leasing, investing, and similar financial businesses.

This matters for Florida founders because Florida's startup ecosystem is concentrated in exactly these industries. Understanding where the lines are drawn is the first step in any QSBS analysis for a Florida-based company.

Healthcare and health services

Florida has the largest healthcare sector of any state by employment, with a major concentration of telehealth companies, digital health platforms, behavioral health firms, and healthcare staffing businesses based in Miami, Tampa, and Orlando. The §1202(e)(3) health exclusion applies to businesses "in the field of health" — which courts and the IRS have interpreted to mean companies whose core revenue comes from the performance of health services. The distinction matters considerably:

• Likely excluded: Telehealth platforms that directly employ physicians and bill for clinical visits. Managed care companies whose product is the delivery of healthcare. Staffing agencies placing nurses and therapists. Clinic networks, regardless of whether technology is used to deliver care.
• Likely qualified: Healthcare software companies (EHR platforms, revenue cycle tools, clinical trial software) where the business develops and sells software but does not perform health services. Medical device companies that design, manufacture, or distribute devices. Biotech and pharmaceutical development companies (drug discovery, gene therapy, diagnostics) — these are technology or manufacturing businesses, not health-service businesses, and are generally not excluded under §1202(e)(3).
• Gray area: Digital health companies with hybrid models — software plus embedded clinical services. AI diagnostic tools that also employ clinicians to review results. Population health platforms that sell analytics and also provide "care management services." The boundary between "health tech" and "performing services in the field of health" is fact-specific and the IRS has not issued comprehensive guidance on every model.

Miami fintech and financial services

Miami has emerged as one of the top fintech hubs in the United States, with a concentration of payment processing, lending, cryptocurrency exchange, wealth management software, and embedded finance companies. Section 1202(e)(3)(A) explicitly excludes "financial services" and "brokerage services," and §1202(e)(3)(B) excludes banking, insurance, financing, leasing, and investing businesses.

For Miami fintech founders, the key question is where the business falls on the spectrum between "technology company that powers financial services" and "financial services company."

• Likely excluded: Companies that hold money transmission licenses and act as principal in money flows. Securities broker-dealers. Registered investment advisors who manage client portfolios as their primary business. Companies whose product is credit origination, insurance underwriting, or investment fund management.
• Likely qualified: Companies whose product is software that financial institutions use — payment infrastructure, compliance tools, core banking platforms — where the company does not itself hold or intermediate funds as a principal. Financial data and analytics platforms that sell data, not financial services. Crypto infrastructure companies that build protocols rather than operating as exchanges or broker-dealers.
• Gray area: Buy-now-pay-later platforms with their own lending operations. Neobanks with banking charters. Embedded finance infrastructure that provides software and holds e-money. Crypto companies with brokerage or custody operations. These businesses often sit on both sides of the technology/financial-services divide, and the QSBS analysis depends on how the company is structured, licensed, and how it earns revenue.

The excluded-industries rule is one of the most commonly overlooked QSBS disqualifiers and is especially relevant to Florida's specific startup ecosystem. A company that looks like "software" in its pitch deck can fall on the wrong side of the §1202(e)(3) line depending on how it earns revenue and is regulated. See the excluded industries guide for the full statutory analysis and industry-by-industry breakdown.

What QSBS saves a Florida founder: worked examples

For a Florida founder with post-OBBBA stock and a full 5-year hold, qualifying QSBS eliminates all $3.56M in federal taxes. Florida's no-income-tax environment means there is no state-level cushion that partially offsets a failed qualification — a Florida founder whose stock fails §1202 faces the full $3.56M federal bill with $0 in state-level offset.

Florida vs. other startup states: QSBS comparison

Florida and Texas are the two largest no-income-tax states with meaningful startup ecosystems. The key QSBS planning difference between them is the industry composition: Texas's startup ecosystem is more heavily concentrated in technology (Austin, Dallas), where §1202 excluded-industry issues are less common. Florida's healthcare, biotech, and fintech sectors make the excluded-industries analysis a more pressing first step for Florida founders than it is for their Texas counterparts.

The California residency trap for founders who moved to Florida

The California-to-Florida migration among startup founders — driven by cost of living, lifestyle, and tax policy — has been substantial, particularly into Miami and Tampa. For these transplants, a critical planning issue exists: California's rules for taxing former residents can create a California tax claim on QSBS gain even after the founder has relocated to Florida.

How the FTB audits post-departure domicile

California taxes residents on worldwide income under Revenue and Taxation Code §17041. The California Franchise Tax Board (FTB) scrutinizes high-income departures closely, particularly when a large capital gain is realized in the first one or two years after a reported move.³ California uses a facts-and-circumstances domicile test: where you maintain your primary residence and spend the majority of your nights; where your spouse and children are based; where your driver's license, voter registration, and professional licenses are registered; where your social and professional connections are; and where your financial accounts and advisors are located.

A founder who reports a Miami address but maintains a home in Los Angeles or the Bay Area, whose spouse and children remain enrolled in California schools, and who returns to California for work or social commitments throughout the year is a likely FTB audit target when a large QSBS gain is reported. The FTB has successfully asserted California residency on founders who believed they had legitimately established domicile in a no-income-tax state.

Florida-specific domicile steps

Florida law provides a formal mechanism to document domicile change: a Declaration of Domicile filed with the county clerk under Florida Statutes §222.17. This establishes a formal legal record of Florida domicile and is stronger evidence than simply updating a mailing address. Other Florida-specific markers include: Florida driver's license, Florida voter registration, Florida professional licenses, enrollment of children in Florida schools, and application for Florida's homestead exemption on your primary residence (which Florida restricts to primary residences — a strong indicator of Florida domicile). Estate planning documents executed under Florida law and naming Florida as your domicile further strengthen the position.

Options compensation sourcing for former California employees

For founders whose equity has a compensation component — ISOs, NSOs, or RSAs granted while working for the company in California — California applies an apportionment formula that allocates a portion of the income to California based on California workdays during the service period from grant to exercise (for options) or from grant to vesting (for restricted stock).⁴ This California-source income may be taxable in California even if the founder is definitively domiciled in Florida at the time of the sale.

Founders who purchased pure founder stock at company formation — shares issued at inception for consideration, not as compensation for ongoing services — generally do not have this California sourcing issue. The gain is a capital event from the outset. The equity-compensation sourcing issue affects primarily founders who held options or restricted stock tied to California employment. See the California QSBS guide for the full analysis of these issues for California-to-Florida transplants.

OBBBA and Florida founders: the 2025 federal changes

The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, made three changes to §1202 that apply to all U.S. taxpayers, including Florida founders.⁵ All three changes are federal — Florida's no-income-tax status does not alter the analysis:

• $15 million exclusion cap for stock issued after July 4, 2025 (up from $10 million). Pre-OBBBA stock issued before that date retains the prior rules: $10 million cap, or 10× adjusted basis, whichever is greater.
• Tiered holding period for post-OBBBA stock: 50% exclusion at 3 years, 75% at 4 years, 100% at 5 years. Pre-OBBBA stock retains the binary rule: 0% before 5 years, 100% at 5 years.
• $75 million gross assets threshold at issuance (up from $50 million). This is particularly meaningful for Florida's capital-intensive healthcare and biotech companies, where research infrastructure and clinical trial costs can push total assets higher relative to a pure software company at the same stage.

The $75M gross assets increase under OBBBA helps Florida biotech and healthcare tech companies specifically. A Florida biotech company with significant IP, laboratory equipment, or clinical infrastructure may have had difficulty staying below the old $50M gross assets threshold by the time it completed a Series B or C. OBBBA's $75M threshold gives these capital-intensive businesses additional qualification room. See the OBBBA changes guide for the full pre/post comparison and the gross assets timing mechanics.

Planning priorities for Florida founders

1. Verify industry qualification before building any QSBS strategy

For Florida founders, industry qualification is the first question — not an afterthought. Have a qualified tax attorney review your company's primary business activity against §1202(e)(3) before assuming QSBS applies. The analysis should address: what the company's primary revenue source is; how the business is described in formation documents, investor materials, and regulatory filings; whether the company holds financial services or healthcare services licenses; and whether revenue comes from delivering health or financial services as principal versus selling software to those industries. See the qualification requirements guide for the full eight-test checklist.

2. Confirm the gross assets test at every issuance date

The §1202 gross assets test applies at the time each tranche of stock is issued — not at the time of sale. For a Florida biotech or healthcare tech company that has raised multiple rounds, the $50M/$75M threshold (pre/post-OBBBA) must have been satisfied at the time each tranche was issued. A company below $50M at Series A but above $75M by Series B may have two classes of stock with different QSBS status. The OBBBA $75M threshold helps later-stage companies, but founders with pre-July 2025 stock from a company that raised substantial capital early need to verify the test was passed at each prior issuance date. See the angel investor guide for how the gross assets trap works across funding rounds.

3. Plan around the 5-year hold threshold for post-OBBBA stock

For founders with post-July 2025 stock, the tiered structure creates a meaningful sub-5-year option (50% at 3 years, 75% at 4 years). But the 28% rate trap makes the 5-year hold by far the most tax-efficient outcome: waiting from year four to year five eliminates over $1.1M in tax on a $15M exit. If a transaction is approaching and you hold post-OBBBA stock, model the year-by-year tax cost before agreeing to a sale timeline. See the holding period guide for how the clock starts for different equity types, including ISOs exercised early, RSAs with an 83(b) election, and SAFEs that converted.

4. Document Florida domicile thoroughly if you moved from California

For California-to-Florida founders, domicile documentation is as important as QSBS qualification documentation. File a Declaration of Domicile with your Florida county clerk (Florida Statutes §222.17). Update driver's license, voter registration, and professional licenses to Florida. Apply for Florida homestead exemption on your primary residence. Track days spent in each state throughout the year. Establish financial relationships with Florida-based or Florida-engaged advisors. Execute estate planning documents under Florida law. Do this well before any transaction — domicile changes that are conveniently timed with a large capital gain draw FTB scrutiny.

5. Use the pre-LOI window for gifting and charitable planning

Florida's no-income-tax environment simplifies the gifting analysis relative to California: there is no Florida gift tax, no state-level apportionment issue on gifted QSBS shares when both donor and donee are Florida residents, and no Florida-specific interaction with the gifted shares. The federal §1202(h) transfer rules and federal gift tax rules govern entirely. Gifting QSBS shares to family members before a definitive agreement or term sheet is signed can multiply the available exclusion by giving each donee their own cap. The IRS issued informal guidance in May 2026 noting that certain "stacking" arrangements may be challenged — have a QSBS advisor review any multi-tier gifting plan before execution. See the gifting and stacking guide for the mechanics, timing rules, and the IRS warning.

6. Plan post-exit federal tax efficiency

Florida's no-income-tax environment eliminates the state tax problem for post-exit investment returns — but federal taxes apply in full. Dividends, interest, capital gains, and ordinary income on reinvested QSBS proceeds are all subject to federal rates. Florida also has no state income tax benefit from Florida-issued municipal bonds beyond what any municipal bond provides (federal tax exemption). Post-exit planning for Florida founders focuses on federal tax efficiency: tax-exempt municipal bonds, direct indexing for tax-loss harvesting, Roth conversion windows in lower-income years after the exit, qualified opportunity zone investments, and estate planning integration. Florida's lack of state estate tax (Florida abolished its estate tax in 2004) also means the post-exit estate plan focuses entirely on federal estate planning — including the $15M federal exemption made permanent under OBBBA. See the post-exit investing guide for the full framework.

Talk to a QSBS advisor about your Florida situation

Florida's no-income-tax environment removes the state QSBS planning problem entirely — but it does not simplify the federal industry exclusion analysis, the qualification verification work, or the pre-transaction planning window. If you hold equity in a Florida healthcare, biotech, or fintech company, that analysis should begin before a term sheet is on the table. If you recently relocated from California, the domicile documentation belongs in that same conversation.
