No, You Won't Avoid Capital Gains by Buying Another Home

It's one of the most common things I hear from senior homeowners: 'We're not worried about capital gains — we're buying another place with the money.' I understand why people believe this. It used to be true. It hasn't been true for nearly thirty years. And the misunderstanding can be an expensive one.

Where the Myth Came From

Before 1997, the tax code included what was known as the rollover rule — a provision that allowed homeowners to defer capital gains tax if they used the proceeds from a home sale to purchase a new home of equal or greater value within a certain timeframe. For decades, this was how it worked. Buy a bigger house, defer the tax. It was real, it was widely used, and it became deeply embedded in how people thought about selling a home.

In 1997, Congress replaced the rollover rule with something entirely different through the Taxpayer Relief Act. The rollover rule was eliminated. In its place came the exclusion most homeowners know today — but many don't fully understand.

The problem is that a generation of homeowners bought their homes before 1997, lived in them for decades, and carried the old understanding with them. Nobody sent a notice. Nobody corrected the assumption. And so here we are, nearly thirty years later, still having this conversation.

How It Actually Works Today

Under current tax law, what matters is not what you do with the money after you sell. What matters is whether you qualify for the home sale exclusion — and if so, how much of your gain it covers.

Here is how the exclusion works:

•       If you are single and have owned and lived in the home as your primary residence for at least two of the last five years, you can exclude up to $250,000 of capital gains from federal tax.

•       If you are married filing jointly and meet the same ownership and residency requirements, you can exclude up to $500,000.

•       Anything above those thresholds is taxable — regardless of whether you buy another home, rent, move to a senior community, or put the money in the bank.

What you do with the proceeds after closing has no bearing on your tax liability. Buying another home does not defer, reduce, or eliminate capital gains. The old rollover rule is gone.

What This Means for Long-Time Homeowners

For seniors who have owned their homes for twenty, thirty, or forty years, this matters enormously. Home values in Orange County have appreciated significantly over that time. Many homeowners who paid $200,000 or $300,000 for their home decades ago are now sitting on properties worth well over a million dollars. That appreciation is a gain — and depending on your cost basis and individual circumstances, a meaningful portion of it may be taxable.

Here's a simple example: a couple who purchased their home for $250,000 in 1990 and sell it today for $1,200,000 have a gross gain of $950,000. After the $500,000 married exclusion, $450,000 remains potentially taxable. Buying a $900,000 condo with the proceeds changes nothing about that number.

This is why I always recommend that any senior homeowner considering a sale connect with their CPA or tax advisor before listing — not after. The timing and structure of a sale can sometimes affect the tax outcome. That conversation is worth having early.

A Few Situations Worth Knowing About

When One Spouse Has Passed Away

This is one of the most important and least understood scenarios. When a spouse passes away, the surviving spouse typically has a two-year window from the date of death during which they can still claim the full $500,000 married exclusion — provided they sell within that period and meet the other requirements. After two years, they file as single and the exclusion drops to $250,000. For homeowners with significant appreciation, the difference can be substantial. Timing matters.

Your Cost Basis May Be Higher Than You Think

Capital gains are calculated on the difference between your sale price and your cost basis — and your basis isn't just what you paid for the home. It also includes the cost of capital improvements made over the years: a kitchen remodel, a room addition, a new roof, upgraded systems. If you've made significant improvements and kept the receipts, your taxable gain may be meaningfully lower than a back-of-the-envelope calculation suggests. This is another reason to talk to a CPA before you sell, not after.

The Step-Up in Basis at Death

For homeowners who inherit a property, the cost basis is typically stepped up to the fair market value at the date of death — which can significantly reduce or even eliminate capital gains on a subsequent sale. This is a separate topic covered in its own post on this blog, but worth mentioning here because it affects how inherited homes are treated differently from homes sold by their original owners.

The Bottom Line

If you are planning to sell a home you've owned for a long time, the single most important thing I can tell you is this: talk to your CPA or tax advisor before you do anything else. Not because the tax picture is necessarily dire — for many homeowners, the exclusion covers a significant portion of the gain — but because knowing your numbers in advance gives you options. Waiting until after the sale does not.

My role is real estate, not tax advice. But part of what I do for my senior clients is make sure they have the right people around them before a transaction — not scrambling to find them after. If you need a referral to a CPA who works with senior homeowners on real estate transactions, I'm happy to make that introduction.

And if you've been carrying the assumption that buying another home protects you from capital gains — now you know. The rule changed in 1997. The conversation with your tax advisor is worth having today.
