The 1997 tax law many longtime Huntington Beach homeowners still misunderstand.

If you've owned a home in Huntington Beach for a long time, there's a good chance you're carrying around a tax rule in your head that hasn't existed since 1997. It's one of the most common things Ratowsky Group at Compass hears when longtime owners start thinking about selling, and it's completely understandable, because the rule used to work the way people remember.

Here's the calm version. The Taxpayer Relief Act of 1997 changed how the gain on your primary home is treated when you sell. Generally, a single filer can exclude up to $250,000 of gain, and a married couple filing jointly can exclude up to $500,000, as long as you meet the ownership and use tests. The rest of this page walks through what that means, what it replaced, and why it lands differently in a town where homes have appreciated for decades. None of this is tax advice, and your situation is your own, so a CPA is the right person to run your actual numbers.

Before 1997, two rules shaped how people thought about selling a home. The first was the old rollover, technically Section 1034, where you could defer the gain by buying a replacement home that cost at least as much as the one you sold. Buy up, push the tax down the road. The second was a one-time exclusion for owners over 55, often remembered as the $125,000 break you could use once in your life. A lot of people built their entire mental model of home selling around those two ideas.

The 1997 law replaced both. There's no more rollover, so buying a more expensive home doesn't defer your gain the way it once did. And the one-time over-55 exclusion is gone too. In their place is a single, cleaner framework: the primary-residence exclusion that generally allows up to $250,000 of gain for a single filer or up to $500,000 for a married couple filing jointly. The big mental shift is that this newer exclusion can generally be used more than once over a lifetime, not just one time, as long as you keep meeting the rules each time you sell.

The current exclusion generally turns on whether the home was truly your primary residence. The common framing is the ownership and use tests: generally, you need to have owned the home and lived in it as your main home for at least two of the last five years before the sale. Meet the tests, and a single filer can generally exclude up to $250,000 of gain, while a married couple filing jointly can generally exclude up to $500,000.

Two details trip people up. First, the exclusion applies to your gain, not your sale price, and gain is the sale proceeds minus your basis, which we'll get to next. Second, those dollar figures are the long-standing statutory amounts, and there are particular rules around second homes, rentals, partial use, and special situations that are well beyond a web page. The takeaway isn't to memorize the fine print. It's to know the framework exists, then let a CPA apply it to your actual numbers, because the exceptions are where real money lives.

Here's where it gets real for longtime owners in this town. Picture someone who bought near the wetlands, in Old Town, or over in Huntington Harbour decades ago, at a price that sounds almost made-up today. Their original basis is low, the home has appreciated for years, and the gain on a sale can run far above $250,000 or $500,000. When that happens, the exclusion may cover part of the gain, and the rest may be taxable. That's the part that genuinely surprises people, and it's better to learn it months before a sale than at the closing table.

This isn't a reason to panic, and it's definitely not a reason to avoid selling. It's a reason to understand your real numbers early. Craig and Justin Ratowsky have worked with owners who held a home for 30-plus years, and the calm move is always the same: get a realistic read on your potential gain, loop in a CPA before you make decisions, and plan with eyes open. The goal is no surprises, just a clear picture of what a sale actually looks like for your household.

Since the exclusion applies to gain, anything that lowers your taxable gain matters, and basis is the lever you actually have some control over. In general terms, your basis starts with what you originally paid, and qualifying improvements over the years can add to it. A higher basis generally means a lower taxable gain, which is exactly why the boxes of old receipts matter more than people think.

If you've owned for decades, the new roof, the addition, the kitchen and bath remodels, the re-piping, the seawall work on a harbor property, all of that can potentially factor into basis under the rules. Routine repairs and maintenance generally don't count the same way as capital improvements, and the line between them has its own definitions, so this is another spot to defer to a CPA. The practical, non-advice takeaway is simple: keep your records. The owner who can document what they put into the home over thirty years generally hands their tax professional a much better starting point than the owner who can't.

Two other topics come up constantly alongside this one, and they're worth naming so you don't blur them together. The first is stepped-up basis at death. In general, when property passes to heirs, the basis can reset to the value at the date of death, which is a separate mechanism from the primary-residence exclusion we've been discussing. The rules are specific, and estate planning belongs with an estate attorney and a CPA, not a real estate page.

The second is Proposition 19, which California voters passed in 2020. Prop 19 affects property-tax basis and certain transfers, and it's a property-tax issue, not an income-tax issue. People sometimes hear "basis" in both conversations and assume they're the same thing. They're not. Income-tax gain on a sale, stepped-up basis at death, and Prop 19 property-tax rules are three different tracks, each with its own professionals. The honest move is to separate them, then bring in the right advisor for each. Ratowsky Group is not a tax or legal advisor, and we're glad to point you toward the right professional for the question you're actually asking.
