Before You Pop the Champagne on That Sale Price, Read This

The market in Westchester is doing something remarkable right now. Bidding wars. Strong offers. Home sale prices that are making longtime homeowners do a double-take at their bottom line.

If you're thinking about selling — or already in the process — that's genuinely exciting news. But there's a conversation I keep having with sellers that doesn't always happen early enough: What are the tax implications of this sale?

I'm a Realtor, not a tax advisor. But part of my job is making sure you walk into this transaction with your eyes open — and that means raising the questions your CPA and real estate attorney will want you to be thinking about before you get to the closing table.

Here's what every seller in today's market should understand.

What Is a Capital Gain — and Why Does It Matter?

When you sell your home for more than your adjusted purchase price (your original price, plus qualifying improvements and certain costs), the profit is called a capital gain. The federal government taxes it. In many cases, New York State does too.

In a market where values have climbed significantly over the past several years, this isn't a hypothetical concern — it's a real number you should know before you list.

The Good News: The Primary Residence Exclusion

Here's where many sellers catch a break. The IRS offers a meaningful exclusion for the sale of a primary residence:

• Single filers can exclude up to $250,000 in capital gains

• Married couples filing jointly can exclude up to $500,000

To qualify, you must have owned and lived in the home as your primary residence for at least two of the last five years before the sale.

What About Married Couples Who File Separately?

If you and your spouse file separate returns, each of you may individually claim up to the $250,000 exclusion — as long as you both meet the ownership and use requirements. That said, filing separately comes with its own set of complications and could limit other benefits. This is exactly the kind of nuance your tax professional needs to walk you through.

Your Receipts Are Worth Money — Here's Why

Now that you understand the exclusion, let's talk about something surprisingly overlooked that can work hand in hand with it: capital improvements you made to your home can directly reduce your taxable gain — but only if you can prove them.

Here's the logic. Your gain isn't simply sale price minus what you paid. It's sale price minus your adjusted cost basis — which is your original purchase price plus documented capital improvements. Every qualifying dollar you spent improving the property increases your basis, which lowers your gain, which reduces what you owe in taxes.

What counts as a capital improvement? Think meaningful, permanent upgrades: a new roof, a kitchen or bathroom renovation, an addition, new windows, a finished basement, a new HVAC system, or significant landscaping. Routine repairs and maintenance — painting a room, fixing a leaky faucet — generally don't qualify.

The catch: you have to prove it. The IRS will want documentation. That means invoices, contracts, and receipts from the contractors who did the work. If you paid and have nothing in writing, that improvement may not count.

Here's a simple example of why this matters:

• You bought your home for $500,000

• You made $150,000 in documented improvements over the years

• Your adjusted cost basis is now $650,000

• You sell for $1,000,000

• Your gain is $350,000 — not $500,000

For a married couple filing jointly, that $350,000 gain falls entirely within the $500,000 primary residence exclusion. Without those documented improvements, you'd be looking at a $500,000 gain — and potentially owing taxes on the portion that exceeds the exclusion.

Start pulling those records now. If you're planning to sell in the next year or two, this is the time to gather whatever documentation you have.

Busting a Common Myth: Buying Another Home Doesn't Defer Your Taxes

I hear this one often: "If I buy another house right away, I won't owe taxes on the sale, right?"

Not under today's tax code — at least not for your primary residence.

Your capital gain is calculated based on the sale itself, regardless of what you do with the proceeds afterward. Knowing this ahead of time can meaningfully change how you think about timing, pricing strategy, and your next steps.

However — and this is where the conversation gets more interesting for some sellers — there is a legal strategy that allows you to defer capital gains taxes when selling real estate. It's called a 1031 exchange, and if you own investment property, it's one of the most powerful tools in the tax code.

What Is a 1031 Exchange — and Could It Apply to You?

A 1031 exchange (named for Section 1031 of the IRS tax code) allows an investor to sell an investment or business property and defer capital gains taxes — as long as the proceeds are reinvested into a qualifying "like-kind" property.

Important distinction: A 1031 exchange does not apply to your primary residence. It is specifically for investment properties — think rental homes, multi-family buildings, commercial real estate, or a second home that has been used as a rental.

But here's why this matters in today's conversation: many of the sellers I work with own more than one property. If you're selling a rental or an investment property alongside — or instead of — your primary home, a 1031 exchange could allow you to defer a significant tax liability while continuing to build wealth through real estate.

Here's how it works:

1. You sell your investment property. Rather than receiving the proceeds directly, the funds go to a qualified intermediary — a neutral third party who holds the money on your behalf. This step is non-negotiable. If the proceeds ever touch your hands, the exchange is disqualified.

2. You identify a replacement property within 45 days. From the date of your sale, you have exactly 45 days to formally identify the property (or properties) you intend to purchase. This deadline is strict — no extensions.

3. You close on the replacement property within 180 days. You must complete the purchase of your like-kind replacement property within 180 days of the original sale. Again, no flexibility here.

4. The gain is deferred — not eliminated. The capital gains tax doesn't disappear; it carries forward into the new property. But deferring it can be enormously valuable, especially if you plan to continue holding real estate long-term or intend to pass property to heirs, where a step-up in cost basis may eventually come into play.

The timing requirements are not suggestions. The 45-day identification window and 180-day closing deadline are IRS rules with no grace period. Missing either deadline means the exchange fails and the full tax liability comes due. Planning has to begin before you close on the sale — ideally months before.

What You Can Do Right Now

Whether you're selling your primary residence, an investment property, or both, here's what I encourage sellers to do proactively:

Gather your improvement records. Invoices, contracts, receipts — anything that documents money you put into the property. These can meaningfully reduce your taxable gain, but only if you can substantiate them.

Think about timing. The two-year ownership and use rule for the primary residence exclusion isn't just a technicality. If you're close to a threshold, a few months can make a significant financial difference.

If you own investment property, ask your advisor about a 1031 exchange early. The planning has to happen before closing — not after. Once the sale is complete, the window has already started.

Talk to your tax advisor before you list — not after you close. The best time to plan is before the transaction, not when you're staring at a closing disclosure.

Loop in your real estate attorney. They and your CPA should be coordinating on your behalf. As your Realtor, I'll make sure we're all aligned.

The Bottom Line

Today's market is giving sellers in our region a real opportunity to maximize their sale price. That's something to celebrate. But the sellers who come out ahead aren't just the ones who get the highest offer — they're the ones who understand the full picture.

My job is to help you get there with clarity, confidence, and as few surprises as possible.
