Direct Indexing in Florida: Retirees, Transplants, and the 23.8% Math

Florida has no state income tax — the same no-state-tax picture as Texas and Nevada. The combined capital gains rate is 23.8% federal only. But Florida's investor population is unlike any other state: it's dominated by wealthy retirees who care deeply about §1014 step-ups and IRMAA management, tens of thousands of former California and New York high-earners who relocated specifically to cut their tax bill, and a rapidly growing Miami finance and private equity community. For all three groups, direct indexing offers something specific and valuable — if the portfolio size and income picture support it.

Florida's capital gains tax picture

Florida has permanently prohibited a personal income tax by constitutional amendment (Art. VII, §5 of the Florida Constitution). This means no state tax on wages, dividends, capital gains, interest, or any other investment income — for any Florida resident.¹

Florida also has no state estate tax and no intangibles tax (the latter was repealed in 2007). For wealthy investors, this makes Florida one of the most complete no-tax environments of any major state — and a logical destination for investors planning a multi-decade accumulation and distribution sequence.

Florida vs. the high-tax states: what moving here actually saves

That last column explains Florida's wealth migration story: a $5M gain realized as a Florida resident instead of a California resident saves $665,000 in state tax. The domicile change strategy is often worth more in dollar terms than direct indexing itself — but the two work together.

The three Florida investor profiles that benefit most from DI

1. Wealthy retirees: §1014 step-up, IRMAA management, and 0% gain harvesting

Florida's largest high-net-worth cohort is retirees. Moving from accumulation to distribution changes the DI calculus in important ways — and makes direct indexing potentially more valuable, not less.

§1014 step-up asymmetry. When a taxpayer dies, the cost basis of taxable account assets resets to fair market value on the date of death (IRC §1014). Unrealized gains vanish. Unrealized losses also vanish — they cannot be harvested posthumously.² A direct-indexed portfolio exploits this asymmetry: harvest losses in life (locking in the deduction), hold positions with embedded gains for the step-up at death. The portfolio progressively shifts toward holding positions where the future tax cost is minimized, while systematically converting loss positions into current tax savings.

IRMAA management. Medicare Part B IRMAA surcharges begin at $109,000 MAGI (single) or $218,000 MAGI (MFJ) for 2026.³ Each additional dollar of capital gain income can push a retiree into the next surcharge tier, adding $81.20–$487 per month to Medicare premiums. A direct-indexed portfolio gives lot-level control: choose which positions to sell, which to hold, and how much gain to realize in a given year — keeping MAGI precisely below a threshold rather than being subject to the uncontrolled capital gains distributions that mutual funds generate.

0% gain harvesting. Florida retirees with taxable income below $96,700 (MFJ) in 2026 qualify for the 0% federal LTCG bracket. For those investors, the right move is often to harvest gains — not losses — up to the bracket limit, realizing appreciation tax-free and resetting cost basis to a higher level. DI's lot-level precision makes this straightforward: identify lots with long-term embedded gains you'd eventually sell anyway, realize them at 0%, and hold loss positions either for future harvesting or for the §1014 step-up.

2. CA/NY transplants: domicile change timing and loss bank deployment

Florida is the most common destination for high-net-worth California and New York residents relocating to reduce their tax burden. The tax savings are real and potentially large — but the domicile change must be done correctly.

Timing matters above everything. Capital gains on assets sold after you become a legal Florida resident are taxed at the federal-only rate. Sell appreciated stock before your FL domicile is established, and California or New York will assert the right to tax those gains at their full rate. The correct sequence: (1) establish FL domicile — Florida driver's license, voter registration, Declaration of Domicile filed with the county clerk, physical presence in Florida as your primary home — then (2) realize appreciated assets.⁴

California and New York audit aggressively. Both states look at where you spend the most days, where your family is, where your doctors, social memberships, and significant possessions are. If you cannot prove Florida is your domicile, they will tax the gains as if you still lived there. Planning the domicile change 12–24 months before a major liquidity event gives time to build a defensible record.

Loss bank deployment. Transplants often arrive with capital loss carryforwards from prior DI years. Those carryforwards deploy against Florida-taxed gains with the same federal benefit — a $100K loss still offsets $20,000–$23,800 in federal tax regardless of your current state. Former Californians who built large loss banks at 37.1% may find those losses remain valuable at 23.8%, particularly against a concentrated stock position or business sale earnout.

RSU coordination. Executives who relocate from California to Florida with unvested RSUs face multi-state sourcing at vesting. The ordinary income component is sourced to the grant-to-vest period, and California will assert tax on the California-sourced fraction. But the long-term capital appreciation after vesting — shares held past a one-year holding period — is taxed where you reside at sale. That gain, realized as a Florida resident, is taxed at federal-only rates. A DI account funded with vest proceeds builds the loss bank against that future appreciation.

3. Miami finance, private equity, and the growing South Florida wealth community

South Florida has become a significant financial services hub. Citadel relocated its headquarters from Chicago to Miami in December 2022; hedge funds, family offices, and crypto firms have followed. PE firms, venture capital, and wealth management practices have established or expanded Miami operations driven by the combination of no state income tax and a growing talent pool.

For this community, the DI use case resembles the K-1 investor and PE professional profile: large, lumpy capital gain events from fund realizations, carried interest dispositions, and concentrated equity positions — but at a 23.8% combined rate. The math is less compelling per dollar than in California or New York, but the absolute stakes are often large enough to justify sophisticated multi-account coordination.

Carried interest — the performance allocation from PE and hedge funds — qualifies for long-term capital gains treatment when the underlying assets are held more than three years (IRC §1061).⁶ A DI loss bank that absorbs a $2M carried interest realization offsets up to $476,000 in federal tax at the 23.8% rate. How much of that offset is achievable depends on how aggressively the DI account can harvest — but the scale of the numbers makes DI compelling even at the lower Florida rate.

Break-even math at 23.8%: platform cost discipline matters more here

At a 23.8% combined rate, each harvested dollar saves 23.8 cents. Whether DI nets positive after fees depends more on platform selection in Florida than in high-tax states.

Break-even harvest rate = fee premium ÷ combined tax rate. Advisor-coordinated platforms often generate higher harvest rates through true cross-account wash-sale protection and tax-year timing, which offsets the higher cost — but the bar is meaningfully higher in Florida than in California, where even expensive platforms clear break-even easily.

Dollar benefit by portfolio size in Florida

Assumes 1.5% annual harvest rate and 0.25% DI fee premium. Actual harvest rates vary with market volatility. A Florida investor with a $5M portfolio still keeps $5,350/year after fees — comparable to what a $1.75M California portfolio generates at the same harvest rate.

When direct indexing doesn't make sense in Florida

• Portfolio under $500K with a mid-cost platform. At 23.8%, the net after-fee benefit at $250K is only $268/year with a 0.25% fee premium. Drop to Frec's 0.06% fee premium and the same portfolio nets $893/year — a meaningfully better case for choosing the low-cost option.
• Retirees already in the 0% LTCG bracket. If your taxable income is below $96,700 MFJ, you pay 0% on long-term gains. Loss harvesting generates no tax benefit and disallows gains that could otherwise be realized tax-free. The correct strategy here is gain harvesting — and a simple brokerage account with careful lot selection achieves it without DI overhead.
• Simple tax pictures with no income events. No K-1 income, no RSU, no concentrated stock, no IRMAA concern, low ordinary income — a low-cost ETF or tax-managed fund delivers most of the benefit at a fraction of the cost.
• Short investment horizons. DI defers taxes, it doesn't eliminate them. If the capital is needed within 3–5 years, the deferral benefit is too short to recoup the fee premium at the 23.8% rate.

Finding a specialist for Florida investors

A direct indexing advisor serving Florida clients needs to understand: §1014 step-up planning in distribution-phase portfolios, IRMAA threshold management using lot-level gain/loss selection, domicile change coordination for CA/NY transplants, and platform selection at the 23.8% rate where fee sensitivity is highest. Most generalist advisors implement DI as a product recommendation without integrating it into the broader estate, Medicare, and domicile plan.
