Capital Gains Tax When You Sell a Knoxville Home (Including a Relocation Move)

Do you owe capital gains tax when selling a house in Tennessee? Tennessee charges no state income tax on the gain, so you only face federal capital gains tax — and most sellers owe nothing thanks to a $250,000 exclusion for single filers and $500,000 for married couples.

When a Knoxville home has gone up in value, the first worry I hear is: “How much of that gain does the government take?” It’s a fair question, and the answer is friendlier in Tennessee than in most states — but there are rules worth understanding before you sign anything, especially if you’re moving out of the area.

I’m Hilmar Castillo, Broker at Castillo Realty here in Knoxville. This is a plain-English walk through how capital gains tax works when you sell, and the relocation exception that helps sellers who haven’t lived in the home very long. One note up front: I’m a Realtor®, not a tax advisor, so treat this as a starting map and confirm your specifics with a CPA.

Tennessee’s part: no state capital gains tax

Tennessee has no state income tax on wages or on investment income. The Hall tax on interest and dividends was fully repealed in 2021, so there’s no state-level tax on the capital gain from selling your home. That means the only capital gains tax you might owe when selling a house in Tennessee is federal.

The federal exclusion most sellers use

The federal government lets you exclude a large chunk of your gain under what’s called the Section 121 home-sale exclusion:

  • $250,000 of gain excluded if you file as single.
  • $500,000 of gain excluded if you’re married filing jointly.

“Gain” is not your sale price — it’s roughly your sale price minus what you paid, minus selling costs, minus qualifying improvements. For a lot of Knoxville homeowners, the gain lands well under those limits, so the federal tax owed is zero.

The two tests you have to meet

To claim the full exclusion, you generally need to pass two tests during the five years before the sale, per IRS Section 121 rules:

  • Ownership test: you owned the home for at least 2 of the last 5 years.
  • Use test: you lived in it as your primary residence for at least 2 of the last 5 years.

Those two years don’t have to be back-to-back, and you generally can’t have used the exclusion on another home sale within the prior two years. Second homes and pure investment properties don’t qualify for this exclusion — that’s a different conversation.

The relocation exception: a partial exclusion

This is the part that matters most for sellers leaving the Knoxville area for a job. If you have to sell before hitting the two-year mark because of a qualifying move, you may still get a partial exclusion. A move generally qualifies when your new job is at least 50 miles farther from your old home than your previous job was.

The partial amount is prorated by how much of the two years you completed. For example, a single filer who lived in the home 12 months before a qualifying job move would get roughly (12 ÷ 24) × $250,000 = $125,000 of exclusion. Health reasons and certain unforeseen circumstances can also trigger a partial exclusion.

If you’re relocating into Knoxville and selling a home elsewhere, the same federal rules apply to that sale — and once you’re a Tennessee resident, future gains skip state tax entirely.

How this fits into your net proceeds

Capital gains is only one piece of what you walk away with. Your true net is your sale price minus mortgage payoff, minus selling costs, minus any tax owed. I build that full picture for every Castillo Realty seller in a personalized net sheet, so you’re not guessing at the number that actually lands in your account. Pair that with a quick call to your CPA and you’ll know exactly where you stand.

Frequently asked questions

Do I pay capital gains tax when I sell my house in Tennessee?

Tennessee has no state income tax on the gain, so you’d only face federal capital gains tax. Most sellers owe nothing because the federal exclusion covers up to $250,000 of gain for single filers and $500,000 for married couples filing jointly.

How do I qualify for the home-sale capital gains exclusion?

You generally must have owned the home at least 2 of the last 5 years and lived in it as your primary residence for at least 2 of those years. The two years don’t need to be continuous, and you can’t have used the exclusion on another sale in the prior two years.

What if I have to sell before two years because of a job move?

You may qualify for a partial exclusion if your new job is at least 50 miles farther from your old home than your previous job was. The amount is prorated by how much of the two-year period you completed; health and certain unforeseen circumstances can also qualify.

Is capital gains based on my sale price?

No. It’s based on your gain — roughly your sale price minus your original cost, selling costs, and qualifying improvements. That figure is usually far smaller than the sale price, which is why many homeowners owe no federal tax.
