The Home Sale Tax Break Has Not Changed Since 1997. It Still Stops at $500,000.

A married couple filing jointly can exclude up to $500,000 of gain on a main home sale. A single homeowner can exclude $250,000. Those caps were written in 1997 and have never been adjusted for inflation.

I have spent 17 years in this market. The conversation I have most often with homeowners is not about price. It is about what they kept.

Most homeowners I sit down with can find the closing papers from the day they bought. Almost none of them can find what they spent in the twenty years after. That gap is the expensive part.

The Cap Was Set in 1997 and Has Not Moved

The exclusion comes from Section 121 of the federal tax code. The numbers are short. $250,000 of gain for a single homeowner, $500,000 for a married couple filing jointly.

Those figures have not changed since 1997. Fort Lauderdale prices have.

A couple who bought here fifteen years ago and held the home is often not near the cap. They are past it.

One thing to be clear about. The exclusion applies to the gain, not to the sale price. Sell at $3,000,000 a home you bought for $2,700,000 and the gain is $300,000. All of it is covered.

You Have to Pass Two Tests First

The exclusion is not automatic. The IRS requires two things.

• Ownership. You owned the home for at least 24 months out of the five years before the sale.
• Use. You lived in it as your residence for at least 24 months of those same five years.

The 24 months do not have to be consecutive. For a married couple filing jointly, only one spouse has to meet the ownership test. Each spouse has to meet the residence test individually.

There is also a look-back. You can take the exclusion only once in any two-year period. Sell another home and exclude the gain, and the next sale inside two years does not qualify.

The Gain Above the Cap Is Taxed, Then Taxed Again

Whatever sits above the exclusion is a long-term capital gain. Federal rates run 0%, 15% and 20%. The 20% rate applies to the extent income passes the 15% threshold.

Then there is a second layer. The net investment income tax adds 3.8%. It starts when modified adjusted gross income passes $250,000 for a married couple filing jointly. For a single homeowner it starts at $200,000.

Here is the part worth knowing. The IRS says excluded home sale gain is not net investment income. The excluded portion is out of reach of the 3.8%. Only the amount above the cap is exposed.

Florida helps. There is no state income tax here, so there is no state capital gains tax on the sale. The federal bill is the whole bill.

I am not going to put this year's bracket thresholds in this post. They move every year, and the number that matters is yours rather than the table's. Your CPA has the current figure.

Basis Is the Only Number You Control

Your gain is the amount you realize minus your adjusted basis. You cannot change what a buyer pays. You can change your basis, and this is where homeowners lose money without knowing it.

Two things raise it. Capital improvements, and selling expenses.

Selling expenses are the easy half. Sales commissions and costs directly tied to the sale come off the price before the gain is figured. Your closing statement captures those.

Improvements are the hard half. They happened years ago, and nobody kept the paperwork.

What Counts as an Improvement, and What Does Not

The IRS test has three parts. Work counts if it adds to the value of the home, prolongs its useful life, or adapts it to new uses. Publication 523 names these:

• Additions. Bedrooms, bathrooms, decks, garages, porches, patios.
• Exterior work. New roofs, new siding, storm windows and doors, insulation.
• Systems. Heating systems, central air conditioning, security systems, lawn sprinklers.
• Interior work. Built-in appliances, kitchen modernization, wall-to-wall carpeting, fireplaces.

There is one rule people miss. Repairs done as part of a larger project count as improvements. Replacing every window during an extensive remodel goes into basis. Replacing one window on its own does not.

What does not go into basis:

• Repairs and maintenance that keep the home in good condition without adding value or prolonging its life. Painting, fixing leaks, filling cracks.
• Improvements that are no longer part of the home.
• Anything with a life expectancy of less than one year when it went in.

The distinction is not about what it cost. A $40,000 paint job is maintenance. A $9,000 built-in is an improvement.

Three Exceptions Worth Knowing

• Partial exclusion. Failing the two-year tests does not always cost you the whole break. Three reasons can preserve part of it. A work relocation of 50 miles or more, a health reason, or an unforeseeable event such as death, divorce, casualty loss or unemployment.
• Surviving spouse. A surviving spouse can use the full $500,000 rather than $250,000. The sale has to happen within two years of the spouse's death, and the survivor cannot have remarried.
• Reporting. A Form 1099-S means you report the sale. It goes on Schedule D and Form 8949, even when the entire gain is excluded.

The Folder I Ask Homeowners to Keep

This is the part I ask about first, and it costs nothing to start today.

Keep one folder for the life of the home. Put the closing statement from the purchase in it. Then add every invoice for work that changed the house rather than maintained it. Contractor invoices, architect fees, the cabinet order, the roof contract.

The IRS says to keep basis records until three years after the return is due for the year you sell. In practice that means records from the year you bought, held three years past the year you leave.

I have watched homeowners rebuild fifteen years of improvements in the three weeks before closing, from memory and bank statements. It is miserable, it is incomplete, and the number always comes in low.

Start the folder now. If you already sold without one, your CPA can still work from bank and card records. It is worth the afternoon.

Before You Go to Market

I am not a CPA, and none of this is tax advice. Take it to one before you act on it.

What I can tell you is when the conversation should happen. It belongs before we talk about price, not in the week before closing. A homeowner who knows their basis knows what the sale actually nets. That changes how they think about timing.
