Most heirs walk into inherited property conversations expecting a large tax bill. The number they're picturing is usually the difference between what the house is worth today and what the original owner paid decades ago — and that gap can look alarming. The reality is almost always friendlier than that, because federal tax law treats inherited property differently than most people realize.
This post explains what you actually owe, what you don't, and where the exceptions are. It's part of our broader resource on selling an inherited house in Tennessee, which covers probate, sale options, and what to expect from the process end to end.

The Single Most Important Concept — Step-Up Basis
In tax law, basis is your starting value for capital gains calculation. When you buy an investment property, your basis is typically what you paid. When you sell, you owe tax on the difference between that basis and the sale price.
Inherited property works differently. Federal law provides a stepped-up basis: your basis in inherited property is the fair market value at the date of the original owner's death — not what they paid for it years ago.
Worked example: Your parent bought a house in 1990 for $68,000. By the time they passed, the house was worth $225,000. That $225,000 is your stepped-up basis. If you sell the house for $230,000, your taxable gain is $5,000. If you sell it at $225,000, your gain is zero.
Without the step-up, you'd be calculating gains against that original $68,000 — a $162,000 taxable gain. The step-up eliminates that decades-long appreciation from your calculation entirely.
One additional rule worth knowing: inherited property is treated as long-term capital gains regardless of how long you've actually held it. Long-term rates (currently 0%, 15%, or 20% at the federal level depending on your income) are lower than short-term rates, which apply to assets held under a year and are taxed as ordinary income. Even if you sell the day after inheriting, you get long-term treatment.
How Capital Gains Are Actually Calculated on Inherited Property
The formula: sale price minus stepped-up basis equals taxable gain.
But the stepped-up basis isn't the only number that works in your favor. You can also subtract:
- Selling costs: agent commissions, title fees, attorney fees paid at closing — these come directly off the net proceeds
- Capital improvements: money spent improving the property after you inherited it (renovations that add value typically qualify; routine maintenance generally doesn't — a CPA can confirm what counts)
Worked example: You inherit a house with a stepped-up basis of $190,000. The estate does $9,000 of pre-sale work on the property. You sell for $197,000 with $13,000 in closing costs and commissions.
- Adjusted basis: $190,000 + $9,000 (if the work qualifies as improvement) = $199,000
- Net proceeds: $197,000 − $13,000 = $184,000
- Result: $184,000 − $199,000 = a loss of $15,000 — no capital gains tax owed
This is the math that surprises most heirs. Modest appreciation, selling costs, and repair expenses often combine to produce little or no taxable gain — particularly when selling within six to twelve months of inheriting, when market value hasn't moved far from the date-of-death basis.
These examples are illustrative only. Your actual numbers will differ. Consult a CPA before assuming your situation matches.
When You Do Owe Capital Gains on an Inherited Home
The step-up resets the clock — it doesn't stop it. Appreciation after the date of death is fully taxable when you eventually sell.
Holding the property for years before selling: If you inherit a house worth $200,000 and sell it four years later for $275,000, your capital gain is $75,000. At long-term rates, a taxpayer in the 15% bracket would owe roughly $11,250 in federal tax — real money, but a fraction of what it would be without the step-up protecting the earlier decades.
Renting the property before selling: This is genuinely complicated. When you rent inherited property, you can claim depreciation deductions against rental income. But when you sell, the IRS may recapture those depreciation deductions — taxing them at rates up to 25%. The interaction between step-up basis, depreciation, and recapture is one of the more complex areas of inherited property taxation. If you've rented an inherited property at any point, do not attempt this calculation without a CPA.
High-value estates: Federal estate tax applies only above the applicable exemption — a threshold that adjusts periodically and is set high enough that most middle Tennessee estates don't come close. A probate attorney will identify whether an estate tax return is required. If it is, a CPA should be involved from the beginning.
Selling below stepped-up basis: If the property has declined in value since the date of death and you sell below your stepped-up basis, you may have a capital loss. Whether and how you can use that loss depends on your broader tax picture — ask a CPA.
If you're navigating an inherited property with siblings who have different plans for timing or the property itself, the tax implications for each heir are separate. See our post on selling an inherited house with siblings in Tennessee for more on that scenario.
Tennessee-Specific Tax Situation
Tennessee is straightforward for heirs:
No state income tax on capital gains. Tennessee does not tax capital gains at the state level. Tennessee eliminated its Hall income tax on investment income in 2021, and no replacement applies to capital gains. See the Tennessee Department of Revenue for confirmation.
No state inheritance tax. Tennessee repealed its state inheritance tax in 2016. Heirs receive inherited property without state inheritance tax regardless of the estate's size.
No state estate tax. Also abolished in 2016.
The practical result: for most Tennessee heirs, federal capital gains is the only real tax exposure — and the step-up basis typically reduces or eliminates it for heirs who sell relatively soon after inheriting. The combination of step-up basis, long-term treatment, selling cost deductions, and no state tax layer makes the tax picture significantly better than most heirs expect when they start asking questions.
Documentation You Need to Get the Step-Up Basis Right
The step-up only works as intended if you can document what the property was worth on the date of death. Without solid documentation, the IRS can dispute your basis claim.
Date-of-death appraisal: A licensed real estate appraiser produces a formal written appraisal with an effective date matching the date of death. This is the gold standard. Estate attorneys typically order this as a standard part of probate — it's also needed for estate accounting purposes.
What if no appraisal was done at the time: This happens more often than it should. Options for reconstructing value:
- Retroactive appraisal: Many appraisers will assign a value to a past date if sufficient comparable sales data exists from that period. The sooner you do this, the easier it is.
- County assessor records: Property tax assessment records around the date of death can provide a starting point, though assessments often lag market value and carry less IRS weight than a formal appraisal.
- Comparable sales analysis: A real estate professional can assemble sold data from the relevant period, which supports — but doesn't replace — a formal appraisal.
The further you are from the date of death, the harder retroactive documentation becomes. If the estate is still in probate or was recently closed, getting an appraisal done now is far easier than attempting it years from now. Ask an estate attorney or CPA to advise on what documentation will hold up for your specific situation.
When to Talk to a CPA (and Why You Probably Should)
This post gives you the framework — not a substitute for professional advice. A CPA familiar with inherited real estate is worth consulting if any of these apply:
High-value property: The step-up math gets more consequential at higher values, and a small error in basis documentation can be expensive.
Property held years after inheriting: New appreciation is fully taxable. The calculation matters more the longer you've held it.
Inherited rental property: Depreciation recapture makes this genuinely complex. Don't assume step-up basis covers the full picture.
Multiple heirs with different timing plans: Each heir's tax situation is individual. One sibling selling in month three and another holding for five years have different exposures even though they started with the same stepped-up basis.
Large estate with federal considerations: If the estate approaches the federal exemption threshold, get a CPA and probate attorney working together from the start.
For background reading before your CPA appointment, IRS Publication 559 ("Survivors, Executors, and Administrators") covers the federal tax treatment of inherited property in authoritative detail. It's dense, but it's the source document.
Frequently Asked Questions
Do I pay capital gains tax on an inherited house in Tennessee?
Usually less than heirs expect. The stepped-up basis means your taxable gain is measured from the date-of-death value, not the original purchase price. If you sell within a reasonable period and the property hasn't appreciated significantly since the date of death, your gain may be small or zero after subtracting selling costs. Tennessee has no state income tax on capital gains and no state inheritance or estate tax, so federal capital gains is the primary exposure — and it's often minimal.
What is stepped-up basis and how does it work?
Basis is the IRS starting value for capital gains calculations. For inherited property, federal law steps that value up to the fair market value on the date of the original owner's death. If a parent paid $55,000 for a house in 1985 and it was worth $210,000 at death, your basis is $210,000. That protects three decades of appreciation from capital gains when you sell.
Do I have to pay tax if I sell an inherited house immediately?
Often no. Selling quickly means the sale price is usually close to the stepped-up basis. Subtracting selling costs often produces little or no net taxable gain. Inherited property also gets automatic long-term capital gains treatment — lower rates than ordinary income — regardless of how quickly you sell. Ask a CPA to confirm your specific numbers before assuming.
Does Tennessee have an inheritance tax?
No. Tennessee repealed its state inheritance tax in 2016 and eliminated its Hall income tax on investment income in 2021. There is no state estate tax and no state tax on capital gains. For most heirs selling an inherited Tennessee property, federal capital gains is the only real exposure.
What if the house was inherited years ago — do I still get step-up basis?
Yes. The stepped-up basis was set at the date of death and doesn't expire. However, any appreciation after that date is fully taxable when you sell. The longer you've held the property since inheriting, the more likely it is you have a real capital gain above your stepped-up basis. A CPA can calculate your actual exposure.
Tax questions stop a lot of inherited property decisions that shouldn't be stopped — heirs assume the worst and delay unnecessarily. Understanding step-up basis usually changes the picture.
