There’s a misunderstanding about the “$250,000 exclusion” that I hear constantly. People think it means: if my house sells for more than $250,000, I owe taxes. That’s not what it means. Not even close.
This confusion is keeping people from making moves they’re financially ready to make. If you’re thinking about downsizing in Tampa Bay and a tax bill is holding you back, read this first.
What the exclusion actually covers
The IRS lets most homeowners exclude up to $250,000 in profit from federal capital gains tax when they sell their primary home. Married couples filing jointly get up to $500,000. To qualify, you generally need to have lived there as your primary residence for at least 2 of the last 5 years.
The key word is profit. Not sale price. Profit. That’s the part most people miss.
How your cost basis changes the picture
To figure out if you have a taxable gain, you need your cost basis. Think of it as what the home actually cost you over the years.
Cost basis = purchase price + capital improvements + eligible buying costs
Capital improvements are things that permanently added value: a new roof, a kitchen renovation, an added room, a new HVAC system. Regular repairs don’t count. Eligible buying costs from your original purchase can also be added in, like transfer taxes and title fees you paid when you bought.
This is for informational purposes only. I’m not a tax professional and nothing here is tax advice. Talk to a qualified CPA before you make any decisions based on your specific numbers.
Taxable gain = sale price minus selling costs minus your cost basis
If the result is under the exclusion threshold and you meet the residency requirement, you likely owe nothing.
A real example of how capital gains tax plays out when you downsize
Say you bought in Land O Lakes for $185,000 in 2006. You added a new roof ($18,000) and renovated the kitchen ($22,000). You paid $3,500 in eligible buying costs at closing. Your cost basis is now $228,500.
You sell today for $510,000 and pay $35,000 in selling costs. Your taxable gain: $246,500. Single? Under the $250,000 exclusion. Married? Well within $500,000. Either way, no federal capital gains tax.
That’s a completely different picture than “I’m selling for over $250,000 so I owe taxes.”
Who actually gets hit?
People most likely to face a taxable gain bought decades ago at a low price, made few improvements, and are selling in a market that’s appreciated a lot. Values across Pasco, Hillsborough, Pinellas, and Hernando counties have climbed substantially over the past decade.
I spoke recently with a woman who was sure she couldn’t downsize because her home was worth $450,000 and she was single. When we worked through the numbers together, her taxable gain came in well under the exclusion threshold. She owed nothing. She’d been putting off a move she was ready for because of a number she’d misunderstood. If you’re wondering whether you’re actually ready to downsize, the tax piece might not be the obstacle you think it is.
What to do before you assume anything
Gather what you know: your original purchase price, a list of major improvements with rough costs, and a realistic sense of what your home is worth today. Take those numbers to a CPA before you make any real estate decisions.
IRS Topic 701 outlines the primary residence exclusion rules. But your CPA is the one who applies them to your situation. What I can help with is the real estate side: what your home is worth now, what selling costs will look like, and what your timeline to downsize and sell realistically looks like.
Again: this is for informational purposes only. Not tax advice. Talk to a CPA before making any decisions.

Questions about capital gains tax when downsizing a home
Does the $250,000 exclusion apply to my sale price or my profit?
It applies to your profit, not your sale price. Profit is your sale price minus selling costs and your cost basis. If your gain is under the exclusion threshold and you meet the residency requirements, you likely won’t owe federal capital gains tax. Have a CPA confirm your specific numbers before you draw any conclusions.
What counts as a capital improvement for my cost basis?
Capital improvements are permanent upgrades that increase your home’s value or extend its useful life: a new roof, added square footage, a kitchen or bathroom renovation, a new HVAC system. Routine maintenance like painting or replacing a faucet generally doesn’t qualify. Your CPA can help identify what counts based on your records.
What if I can’t find all my improvement records?
Do what you can to reconstruct them: permit records, bank statements, old contractor invoices. Even partial documentation helps reduce your taxable gain. A CPA who handles real estate transactions can work through what’s provable and what the IRS allows when records are incomplete.
Downsizing in Tampa Bay? You don’t have to figure this out alone.
I work with homeowners across Pasco, Hillsborough, Pinellas, and Hernando counties who are ready to downsize but have real questions about the process. I can’t give you tax advice, but I can tell you what your home is worth, what selling costs look like, and what the timeline typically is. Once you have that picture, your CPA fills in the tax piece.
