Capital Gains Tax on the Sale of a Home

Most Jacksonville homeowners who sell a primary residence never pay capital gains tax on the sale, because Section 121 of the Internal Revenue Code excludes up to two hundred fifty thousand dollars of gain for a single filer and up to five hundred thousand dollars for a married couple filing jointly, provided the owner lived in the home as a principal residence for at least two of the five years before the sale. For most homeowners in Duval, Clay, St. Johns, and Nassau counties, this exclusion fully absorbs the gain on a typical home sale, meaning no federal capital gains tax and no Florida state tax, since Florida does not tax income at the state level.

The calculation changes once the gain exceeds the exclusion amount, which has become more common as Northeast Florida home values have risen over the past decade, particularly in coastal and near-downtown neighborhoods. Gain above the two hundred fifty thousand or five hundred thousand dollar threshold is taxed as a long-term capital gain if the home was owned for more than one year, at federal rates up to twenty percent, plus a possible three and eight-tenths percent net investment income tax for higher earners. A homeowner should also account for capital improvements made over the years, such as a kitchen renovation, an added room, or a new roof, all of which increase the cost basis and reduce the taxable gain, as well as selling costs such as real estate commissions and closing fees, which also reduce the gain.

The home sale exclusion under Section 121 applies only to a primary residence and is unavailable for a rental property, a vacation home used primarily for personal enjoyment, or a property that was never the seller's main home. A 1031 exchange, by contrast, applies only to property held for investment or business use, not to a personal residence, so a homeowner selling a primary residence generally cannot combine the Section 121 exclusion with a 1031 exchange on the same property, though special rules exist for a home that was converted from a rental into a residence, or a residence that includes a home office or rental unit used for business purposes.

Homeowners who anticipate a gain above the exclusion amount, who have used part of the home for rental or business purposes, or who are selling a property that was inherited or received in a divorce should review their specific facts before listing, since the two-year ownership and use tests, the frequency limitation on using the exclusion more than once every two years, and the treatment of any depreciation claimed on a home office can each change the outcome. For homeowners converting a former rental into a primary residence, or vice versa, understanding how the two tax provisions interact before a sale can prevent an unexpected tax bill.
