Please note: This article is general information about how home-sale taxes usually work in the United States. It is not tax advice. Tax situations are personal — a short conversation with a CPA or tax attorney before you close is money well spent.
The tax follows the profit, not the payment method
When you sell a house, the taxable event is the sale itself. Your potential tax is on the gain — roughly, what you sell for (minus selling costs) minus your basis, which is generally what you paid for the house plus the cost of major improvements over the years. If there's a gain, it may be taxable as a capital gain. If you sell for less than your basis, there's no gain to tax. The closing is reported to the IRS on a Form 1099-S in most cases, cash buyer or not, so assume the sale is on the record and plan accordingly.
The primary-residence exclusion does most of the work
For most people selling the home they live in, one rule covers nearly everything: if you've owned the house and used it as your main home for at least two of the five years before the sale, you can generally exclude up to $250,000 of gain if you're single, or $500,000 if you're married filing jointly. Most longtime South Florida homeowners who sell their own home owe no federal tax on the gain at all, even after big appreciation — the exclusion simply absorbs it.
The details have teeth, though: prior use of the exclusion within two years, a home office or rental period, or a sale because of a move for work or health can all change the math. That's CPA territory, and it's exactly the kind of question worth asking before you sign, not after.
