Capital Gains Tax When Selling a Tampa Bay Second Home in 2026

How is the sale of a Tampa Bay second home or vacation property taxed?

Selling a Tampa Bay second home or vacation property triggers federal long-term capital gains tax — typically 15% or 20%, plus a 3.8% Net Investment Income Tax for higher earners — on the gain above your adjusted cost basis. Florida charges no state capital gains tax, which is the headline advantage. But the IRS Section 121 exclusion that lets primary-residence sellers exclude $250,000 (single) or $500,000 (married) of gain does not apply to second homes. Three planning levers — basis tracking, a 1031 like-kind exchange for property held for investment, and converting the home to a primary residence before sale — determine how much of the gain you actually keep.

 

You bought a Davis Islands waterfront home as a second residence in 2014 for $900,000. It’s worth $2.6 million today. You’re ready to list. The math you’ve heard about — sell your home, exclude the first $500,000 of gain — doesn’t apply, and the federal tax bill is bigger than most owners expect.

Tampa Bay has been a destination second-home market for decades. Snowbirds from the Northeast and Midwest, out-of-state investors, and retirees in transition all hold properties here that aren’t primary residences. The capital gains conversation lands differently for these owners than it does for the typical primary-residence seller — and the planning window is real, but short.

Here’s how the federal tax math works on a Florida second-home sale, where the planning levers are, and the questions you’ll want to bring to your CPA before you list.

Why the Section 121 exclusion doesn’t apply to a Tampa Bay second home

Most homeowners have heard about the $250,000-or-$500,000 capital gains exclusion. That’s IRS Section 121, and per IRS Publication 523 and 26 U.S.C. §121, it has two requirements an owner must meet to claim it:

• Ownership: Owned the home for at least two of the last five years before sale.
• Use: Used the home as a primary residence for at least two of the last five years before sale.

A Tampa Bay home you bought as a second residence — whether it sits in Snell Isle, Harbour Island, Bayshore Beautiful, or Avila — fails the use test. Per Section 121’s definition, the exclusion applies to a principal residence, not a vacation property or investment home. Owners who file Florida homestead on a primary residence elsewhere, or who simply spend most of the year in another state, generally cannot use the exclusion on the Tampa property.

There’s an exception worth knowing about. Section 121 includes a “look-back” rule that allows a partial exclusion if a sale is forced by a change in employment, a health condition, or other unforeseen circumstances. The math is prorated based on how long the owner met the use test. For owners whose plans changed, this is a CPA conversation, not a do-it-yourself one.

The federal tax stack on a Florida second-home sale

For property held more than a year — which describes virtually every second-home sale — the federal long-term capital gains rates apply. Per IRS Topic 409 and the IRS’s published 2026 brackets, those rates are:

• 0% up to about $49,450 of taxable income for single filers (about $98,900 married filing jointly)
• 15% from there to roughly $545,500 single (about $613,700 married)
• 20% above those thresholds

Most Tampa Bay second-home sellers at the $1M+ price point land in the 15% or 20% bracket once the gain is added to the rest of the year’s income. On top of that, the Net Investment Income Tax (NIIT) adds 3.8% on investment income above $200,000 single or $250,000 married filing jointly.

The state-level math is simple. Florida has no state income tax and no separate state capital gains tax. That’s a meaningful advantage compared to selling a comparable property in California, New York, or New Jersey, where state-level capital gains can run another 5%–13% on top of the federal rate. For owners relocating from a high-tax state to Florida, the timing of the sale relative to establishing Florida residency matters — but for a second home that has never been a primary residence, only the federal stack applies.

There’s a separate rule for any Tampa Bay property that has ever been used as a rental. Per IRS rules, depreciation taken (or that should have been taken) during rental periods is recaptured at sale at a federal rate of up to 25%. That’s the “unrecaptured Section 1250 gain” line item, and it surprises owners who rented the home for a few seasons through a property manager and assumed depreciation was optional. It wasn’t. For a deeper look at how that rental-conversion decision interacts with the broader sell-or-hold question, the Gulf Beach market walks through the kind of waterfront properties that frequently move between primary, secondary, and rental status.

A worked example, $900K basis to $2.6M sale

Walk a representative Tampa Bay second-home sale through the math.

• Purchase price (2014): $900,000
• Improvements over twelve years: $200,000
• Adjusted cost basis: $1,100,000
• Sale price (2026): $2,600,000
• Selling costs (commissions, doc stamps, title): roughly $200,000
• Net amount realized: $2,400,000
• Gain on sale: $1,300,000

If the owners are married filing jointly with other taxable income above $613,700, that gain is taxed at 20% federal long-term capital gains, plus 3.8% NIIT on the portion above the $250,000 NIIT threshold. The federal liability runs about $260,000 in capital gains plus roughly $49,400 in NIIT — call it $309,000 in federal tax.

Same property in California with a similar income profile? Add roughly 13.3% in state-level tax on the gain, or another $172,900. Florida saves the seller close to that figure on this transaction, which is why no-state-tax math is part of why so many luxury second-home owners hold here in the first place.

Three planning levers worth knowing about

These are the three plays Tampa Bay second-home sellers most often discuss before listing. None of them is a substitute for a CPA — but the framing matters because the planning window opens before the listing, not after.

• Track basis carefully. Adjusted cost basis is the purchase price plus capital improvements (roof, kitchen renovation, dock or seawall replacement, addition, pool installation, hurricane-hardening upgrades) minus any depreciation taken. The bigger the basis, the smaller the gain. For a property held since 2014, that documentation often lives in old emails, contractor invoices, and receipts that are easier to assemble before the sale than during the closing.
• Consider a 1031 like-kind exchange — only if held for investment. Section 1031 of the Internal Revenue Code allows a seller to defer capital gains by rolling the proceeds into another investment property. Per IRS guidance, the seller has 45 days from sale to identify replacement property and 180 days to close. The catch: the home must be held for investment or business use, not personal use. A pure second home that’s used by family and friends doesn’t qualify. A property that’s been rented consistently — typically for at least two years before the exchange, though the rules require more nuance than a single threshold — may. This is a CPA-and-qualified-intermediary conversation.
• Convert to a primary residence before sale. If the owner moves into the Tampa Bay home as a primary residence and meets the two-of-five-years use test, a partial Section 121 exclusion may become available — though under current rules, the exclusion is reduced to reflect the years of “non-qualified use” before the conversion. The math has gotten less favorable over the past several Tax Code revisions, but for a long-term holder converting to primary residence at retirement, it can still meaningfully reduce the gain.

Florida-specific notes that matter at sale

Two Florida-specific items show up at the closing table on a second-home sale and don’t always come up before:

• Documentary stamps on the deed are paid by the seller. That’s $0.70 per $100 of sale price in Hillsborough, Pinellas, and Pasco counties. On a $2.6M sale, that’s $18,200 — a real line item on the seller’s net sheet, separate from federal capital gains.
• FIRPTA applies to non-U.S. seller-citizens. If the owner is a foreign person under the Foreign Investment in Real Property Tax Act (FIRPTA), the buyer is required to withhold 15% of the gross sale price at closing for transmission to the IRS, regardless of the actual federal tax liability. Tampa Bay sees its share of foreign-owner second-home sales, and FIRPTA planning happens before closing, not at it.

If you’re weighing the sale of a Tampa Bay luxury second home, particularly one that’s appreciated significantly since purchase, the right sequence is usually CPA first, agent second, listing third. The order matters because the basis review and the entity, exchange, or conversion question are easier to address before a buyer is sitting at the table.

 

Frequently Asked Questions

Does Florida charge a state capital gains tax on a Tampa Bay second-home sale?

No. Florida has no state income tax and no separate state-level capital gains tax. Sellers owe federal long-term capital gains and, for higher earners, the 3.8% Net Investment Income Tax — but no state tax on the gain. That’s a meaningful difference compared with selling a comparable property in California, New York, or New Jersey.

Can I use the $500,000 capital gains exclusion on a Tampa Bay vacation home?

Generally not. The IRS Section 121 exclusion of $250,000 (single) or $500,000 (married filing jointly) applies only to a principal residence. A property held as a second home or vacation home fails the two-of-five-years use test. A partial exclusion may be available if the property is converted to a primary residence and held for the required period, or in narrow change-in-circumstance cases — but those require CPA review.

What is depreciation recapture, and does it apply to my Tampa Bay second home?

Depreciation recapture applies if the property has ever been used as a rental and depreciation was taken (or could have been taken) on tax returns. At sale, that depreciation is recaptured as “unrecaptured Section 1250 gain” and taxed at a federal rate of up to 25%. Pure second homes never used as rentals are not subject to recapture, but owners who rented the home for even a few seasons should verify with their CPA before listing.

Can I do a 1031 like-kind exchange on a Tampa Bay second home?

Only if the home is held for investment or business use, not personal use. Per IRS rules, the seller has 45 days from sale to identify replacement property and 180 days to close, using a qualified intermediary. A second home used primarily for family use generally doesn’t qualify. A property that has been rented consistently — typically for at least two years before the exchange, with limited personal use — may. The mechanics require a CPA and a qualified intermediary set up before the closing.

How much is the documentary stamp tax on a Tampa Bay luxury second-home sale?

In Hillsborough, Pinellas, and Pasco counties, the documentary stamp tax on the deed is $0.70 per $100 of sale price. On a $1.5M sale, that’s $10,500. On a $3M sale, $21,000. The seller customarily pays the doc stamp tax on the deed at closing in Florida, and the line item shows up on the seller’s net sheet alongside title, prorations, and commission.
