Short Answer
Most Naples sellers owe nothing: if you owned and lived in the home as your primary residence for two of the five years before the sale, up to $250,000 of gain is excluded for single filers and up to $500,000 for married couples filing jointly. The limits are fixed, and Florida has no state capital gains tax.
It is one of the questions sellers ask the most, and the good news is that most Naples sellers owe no capital gains tax at all. The federal home sale exclusion is generous, and Florida adds no state income tax on top of it. But the rules have details, and there is a widespread misconception that the exclusion grows with inflation, which it does not.
The Exclusion Most Sellers Get
Under the federal home sale exclusion, a single filer can exclude up to $250,000 of gain on the sale of a primary residence, and a married couple filing jointly can exclude up to $500,000. To qualify, you must have owned and used the home as your principal residence for at least two of the five years ending on the date of sale. The two years do not need to be consecutive, and the ownership and use tests do not have to overlap. In Naples, where a well-held home has appreciated significantly, that exclusion is the difference between a taxable event and a non-event for most sellers.
It Is Not Indexed for Inflation
The $250,000 and $500,000 limits have been fixed by statute since 1997, and they are not adjusted for inflation. You will see occasional claims that the exclusion rises with the cost of living, but for a sale in 2026 the limits remain exactly what they have been: $250,000 for single filers and $500,000 for married couples filing jointly. If your gain exceeds the exclusion, the excess is taxable at federal capital gains rates, so the planning question is not whether you qualify, but how much of your gain sits above the line.
Florida Has No State Capital Gains Tax
Florida has no personal income tax, which means there is no state capital gains tax on the sale of your home. The federal exclusion is the entire tax picture for most sellers, and the state's homestead exemption and property tax rules are separate questions that affect your annual bill, not the sale itself. For a Florida resident selling a qualifying primary residence, the federal exclusion is the number that matters.
What Does Not Qualify
The exclusion applies to a principal residence, not to an investment property or a second home. If you rented the Naples home out, or used it only part of the year, the ownership-and-use test can fail, and the gain is treated differently. If you sell before owning two years, the exclusion is reduced or lost unless you sold because of a change in health, employment, or an unforeseen circumstance, which can qualify you for a partial exclusion. If a sale falls short of the two-year test, that partial-exclusion question is worth a conversation with your tax advisor.
Plan Before You List
The sale price, your cost basis, and any improvements you made all feed into the gain, so keep the records of capital improvements. A renovation that is documented can raise your basis and lower the taxable gain. None of this replaces advice from a CPA, and I am not one, but I see the consequences of unplanned sales every year, so I raise the tax question with every seller early, before the timing is locked in.
Key Things to Remember
- Single filers can exclude up to $250,000 of gain, married couples filing jointly up to $500,000, on a qualifying primary residence.
- You must have owned and lived in the home two of the five years before the sale; the two years need not be consecutive.
- The exclusion has been fixed by law since 1997 and is not inflation-indexed.
- Florida has no state income tax, so there is no state capital gains tax on the sale.
- Investment properties and second homes do not qualify; keep records of capital improvements to raise your basis.
