Selling a Florida Second Home: Why the $250,000 Exclusion Does Not Apply

The Question Ted and Marlene Asked Before Listing

Ted, 66, and Marlene, 64, have owned a beach condo in New Smyrna Beach for nine years. They drove down from Atlanta on long weekends, watched the Atlantic from the balcony, and assumed they had built up a tidy gain. When a neighbor recently sold a similar unit for close to the Zillow Home Value Index typical value of $455,000 for the area (July 2026), they started doing the math. They also started wondering whether the IRS would take a large slice of it.

Their first question to their Atlanta accountant was the same one I hear from sellers all along the Florida coast, from Palm Coast down through New Smyrna Beach and over to DeLand: "We have owned it for more than two years. Do we get the $250,000 or $500,000 exclusion?" The answer is no, and this guide explains precisely why, what the rules actually require, and what options a couple in their position should consider before signing a listing agreement. Ted and Marlene are a composite example, not actual clients, but their situation reflects what I see regularly in practice.

What Section 121 Actually Requires

The federal tax code, at Internal Revenue Code Section 121, allows a homeowner to exclude up to $250,000 of capital gain from income when selling a primary residence, or up to $500,000 for a married couple filing jointly. That is the rule that generates the most optimism among vacation-home sellers, and the most disappointment once they read the fine print.

Ownership alone is not enough. The law imposes two separate tests. First, the owner must have owned the property for at least two of the five years immediately before the sale. Second, the owner must have used the property as a primary residence for at least two of those same five years. Ted and Marlene pass the ownership test easily after nine years of title. They fail the use test completely. Weekend and vacation use, no matter how frequent or how affectionate, does not count as primary-residence use under the statute. The IRS treats the word "principal" seriously: it means the one place where you primarily live, sleep, and receive mail as your permanent home.

Because they fail the use test, the Section 121 exclusion is simply unavailable. Their entire net gain is subject to federal capital gains tax. Florida imposes no state income tax, no state capital gains tax, and no state estate or inheritance tax, which is a genuine advantage. But the federal bill can still be substantial.

How Big Could the Tax Bill Be

Assume Ted and Marlene paid $240,000 for the condo in 2017 and sell it today for $455,000. After accounting for closing costs and any capital improvements (a topic for their CPA), suppose their net taxable gain is roughly $190,000. Because they have held the property for more than one year, that gain qualifies as a long-term capital gain rather than ordinary income, which is the better outcome.

For 2026, the long-term capital gains rate is 0% for taxable income up to $49,450 for a single filer, 15% for income between $49,450 and $545,500, and 20% above $545,500, for single filers. For married couples filing jointly in 2026, the 20% rate begins above $613,700. Because Ted and Marlene have retirement income and Social Security, their combined taxable income will likely place at least a portion of the gain in the 15% bracket. An additional 3.8% Net Investment Income Tax applies if their modified adjusted gross income exceeds $250,000 for a couple filing jointly, which is a real possibility in the year of a sale. Their CPA, not their real estate agent, must run these numbers.

The takeaway is that a couple at their income level could easily face a combined federal rate of 15% to nearly 19% on their gain, with no state tax layered on top. That is the baseline from which every planning strategy tries to depart.

Could They Convert the Condo to a Primary Residence

Technically, yes. If Ted and Marlene moved to New Smyrna Beach, established Florida domicile, and lived in the condo as their primary residence for at least two of the five years before they eventually sold it, they would pass the use test and qualify for the exclusion on the portion of the gain attributable to that period of qualifying use.

Here is the complication the tax law added after 2008. Congress enacted what practitioners call the nonqualified-use rule, which provides that the exclusion does not apply to the portion of gain allocated to periods of nonqualified use. In plain terms, if you owned the property for nine years before you moved in, and you then live there for two years before selling, the gain is prorated. Only the fraction of the ownership period that represents qualified use can be sheltered. Roughly two-elevenths of an eleven-year total hold (two years of qualified use divided by eleven years of total ownership) would be excludable, and the remaining nine-elevenths would still be taxable. For a large gain, that proration still leaves a meaningful tax bill. The conversion strategy is not useless, but it rarely eliminates the problem the way sellers hope it will.

There is also the practical matter of actually living there. Selling an Atlanta home, establishing Florida domicile for property-tax purposes (the homestead application deadline is March 1 of the first year you claim the benefit), and committing to two full years of Florida residency is a real life change, not a tax footnote.

The Step-Up Option: Holding Until Death

Federal law provides that assets included in a decedent's estate receive a stepped-up income-tax basis equal to the fair market value at the date of death. If Ted held the condo until he died and it was worth $455,000 at that point, Marlene (or any heir who inherited it) would take a basis of $455,000. A subsequent sale at or near that price would produce little or no capital gain and no federal income tax on the appreciation that built up during Ted's lifetime.

This is a powerful planning tool, but it requires either dying before selling (not a plan most clients endorse) or holding the asset long enough that the strategy aligns with natural events. For a couple in their mid-sixties with a meaningful unrealized gain, the step-up conversation belongs in an estate planning session with an attorney, not just a closing meeting. It is worth knowing that Florida imposes no state estate tax or inheritance tax of its own, so the only estate-tax layer to consider is the federal one.

The 1031 Exchange Option for a True Rental

If Ted and Marlene had been renting the condo to tenants rather than using it personally, a 1031 exchange under Internal Revenue Code Section 1031 would allow them to defer the gain by rolling proceeds into a replacement investment property. The IRS requires strict adherence to identification and closing deadlines (forty-five days to identify replacement property and one hundred eighty days to close), and the property must be held for investment or productive use in a trade or business, not for personal enjoyment.

Because their condo was a personal-use vacation property, not a rental, a straight 1031 exchange is not available on a clean basis. Some owners with a mixed-use property have converted it to a full rental for a period before attempting a 1031, but that strategy carries its own risks and requires careful guidance. I have written separately about how real estate commissions work in Florida after the NAR settlement, which affects what sellers net after a sale and is worth reviewing before setting your listing price.

What This Meant for Ted and Marlene

After reviewing their situation, Ted and Marlene faced a clear-eyed choice. Selling now meant paying long-term capital gains tax on the full gain, with no Section 121 exclusion available because they had never used the condo as their primary residence. Depending on their total income in the year of sale, their federal rate on the gain would likely fall between 15% and 18.8%, with no Florida state tax on top. On a rough gain of $190,000, that could represent $28,500 to $35,700 in federal taxes owed. That is a real number, but it is also the cost of nine years of appreciation in one of Florida's most popular beach markets.

They decided the smarter step before listing was a meeting with their CPA to calculate the actual gain after accounting for closing costs paid in 2017, capital improvements over the years, and the likely income picture in 2026. The CPA would also model whether a two-year conversion to primary residence made sense given the nonqualified-use proration, and whether holding the property as part of their estate plan had merit. Only after that conversation would they be ready to price the condo and list it.

From a pricing and market standpoint, New Smyrna Beach remains a sought-after destination, and the Zillow Home Value Index placed the typical home value there at $455,000 as of July 2026. Getting the listing price right, understanding disclosure obligations under Florida law, and negotiating a contract that protects their interests are all places where having an attorney-REALTOR® on the same side of the transaction adds real value.

The Bottom Line Before You List

The Section 121 exclusion is one of the most valuable tax benefits in the federal code. It is also one of the most frequently misunderstood. Ownership time does not substitute for primary-residence use time. A beach condo in New Smyrna Beach, a weekend retreat near Flagler Beach, or a vacation home anywhere along the Volusia or Flagler County coast will not qualify simply because you have loved it for a decade.

Before you list a second home or vacation property, take these steps:

• Meet with a CPA or tax professional to calculate your actual adjusted basis and projected gain, not an estimate.
• Ask your tax advisor to model the conversion-to-primary-residence scenario using the nonqualified-use proration, so you know the real tax savings, not a theoretical maximum.
• If the property has rental history, ask whether a 1031 exchange is feasible given your hold period and use pattern.
• If you are in your sixties or older with a large unrealized gain, discuss the step-up-at-death strategy with an estate planning attorney before deciding to sell.
• Once you have the tax picture, work with a REALTOR® who understands both the market and the legal landscape to price the property competitively and protect your interests through closing.
