What’s Your Basis in Inherited Rental Property? (w/Examples) + FAQs

This article reflects federal tax rules as of June 2026 and covers tax year 2025 (the 2026 filing season). State rules are noted where they differ. Tax law changes — confirm current figures with the IRS or a licensed professional before you file. This guide is educational and is not a substitute for personalized advice from a CPA, tax attorney, or estate attorney for your specific situation.

Quick Answer

Your basis in inherited rental property is its fair market value on the date the previous owner died — not what they originally paid. This “stepped-up basis” usually wipes out decades of gain and resets the depreciation clock for tax year 2025. You may also use a value six months after death if the estate elects it.

Why This Matters Right Now

When you inherit a rental house, the single number that controls your future tax bill is your basis — the dollar figure the IRS lets you subtract from a future sale price before it taxes your profit. Your basis is reset to the property’s fair market value on the date of death, so every dollar the property gained while your relative owned it can disappear from your taxable gain. Get this number wrong and you may overpay capital gains tax by tens of thousands of dollars, or hand the IRS an excuse to set your basis at zero.

Inherited real estate is not a small corner of the tax code. The IRS expects a historic wave of wealth transfer, and real estate is the largest single asset in most estates, according to the Federal Reserve’s wealth data. That means millions of new landlords are about to face the same question you have, often under a filing deadline, while also deciding whether to keep renting the property or sell it.

What “Basis” Actually Means

Basis is your investment in a property for tax purposes. It is the starting number the IRS uses to measure your gain or loss when you sell, and the number you depreciate over time while you rent the property out.

For property you buy, basis starts at your purchase price plus closing costs and improvements. For property you inherit, the rules change completely. Under Internal Revenue Code Section 1014, your basis is the fair market value of the property on the date the owner died. This is called a “stepped-up basis” because real estate values usually rise, so the basis steps up from the old cost to today’s value.

The consequence is enormous. If your aunt bought a rental in 1985 for $40,000 and it was worth $400,000 when she died in 2025, your basis is $400,000, not $40,000. The $360,000 of gain that built up during her lifetime is simply erased for income-tax purposes. If you sold the day after you inherited it for $400,000, your taxable gain would be zero.

A common misconception is that you inherit the previous owner’s original cost or their “adjusted basis.” You do not. The death of the owner severs the old basis history, and a fresh number takes its place — which is exactly why heirs so often pay far less tax than they fear.

What you should do: get the date-of-death value documented in writing right away, because that single figure anchors every tax calculation you will make for as long as you own the property.

How to Calculate Your Stepped-Up Basis

The default rule is simple to state and powerful in effect: your basis equals the property’s fair market value on the date of death. Fair market value is the price a willing buyer and willing seller would agree on, neither under pressure, both informed.

The Date-of-Death Value

The valuation date is the date the owner died, full stop. Market swings before or after that date do not matter under the default rule. For a rental property, you establish this value with a qualified appraisal, a broker’s price opinion, or — less ideally — comparable sales near that date.

If your relative died on March 3, 2025, you need the property’s value as of March 3, 2025. A retroactive appraisal (an appraiser valuing the property “as of” a past date) is the gold standard because it gives you defensible written support if the IRS ever questions your number. The consequence of skipping documentation is steep: with no proof, the IRS can argue your basis is low or even zero, taxing nearly the entire sale price.

What you should do: order a date-of-death appraisal within a few months of the death, while comparable sales and the property’s condition are still easy to document.

The Alternate Valuation Date

The estate can instead elect to value all assets six months after the date of death under IRC Section 2032. This is the “alternate valuation date.” It is an all-or-nothing election covering the entire estate, not a single asset, and it can only be elected if it lowers both the gross estate value and the federal estate tax due.

There is a key wrinkle for rentals you sell quickly. If the property is sold, distributed, or otherwise disposed of within those six months, it is valued on the date of disposal, not the 6-month date, per the rule in Section 2032.

A common misconception is that any heir can pick the alternate date to suit their own income taxes. Only the estate’s executor can elect it, only on the federal estate-tax return (Form 706), and only when an estate is large enough to owe estate tax. For 2025, the federal estate tax exemption is $13.99 million per person, so most estates never file Form 706 and the alternate date never comes into play.

What you should do: ask the executor which valuation date the estate used, then use that same value as your basis — the two numbers must match.

Adding Your Own Costs After You Inherit

Your basis does not freeze at the date-of-death value. Capital improvements you make — a new roof, an addition, a full kitchen remodel — add to your basis. Routine repairs and maintenance do not; they are deductible expenses instead.

While you rent the property, depreciation you claim reduces your basis over time, producing an “adjusted basis.” This matters because your gain at sale is measured against adjusted basis, not the original stepped-up figure. The consequence of forgetting this: you may understate your gain and underpay tax, which can trigger IRS penalties and interest.

The Land vs. Building Split

You cannot depreciate land — only the building and certain improvements. So before you can claim depreciation on an inherited rental, you must split your stepped-up basis into a land portion and a building portion, because land is never depreciable.

Say your total stepped-up basis is $400,000. If the land is worth $100,000 and the building $300,000, only the $300,000 building portion is depreciable. Skipping this step and depreciating the full $400,000 overstates your deductions, and the IRS can disallow the excess, hitting you with back taxes and penalties.

The most common methods to find the split are the county tax assessor’s land-to-building ratio applied to your basis, or a qualified appraisal that separates the two. The assessor method is popular because it is cheap and accepted: if the assessor shows land as 25% of total value, you treat 25% of your basis as land.

What you should do: document your land/building split in writing the first year you rent the property, and keep it consistent every year after.

Depreciation Recapture Vanishes at Death

Here is one of the biggest hidden gifts of inheriting a rental. When the original owner rented the property, they claimed depreciation deductions each year. Normally, when a landlord sells, the IRS “recaptures” that depreciation and taxes it at rates up to 25%, called unrecaptured Section 1250 gain.

At death, that built-up recapture is wiped clean. Because your basis steps up to fair market value, the previous owner’s depreciation history does not carry over to you. You start fresh, with zero accumulated depreciation, even though your relative may have depreciated the property for 20 years.

Then a new depreciation schedule begins for you, based on your building basis. Residential rental property is depreciated over 27.5 years using the straight-line method on Form 4562; commercial rental uses 39 years. So if your building basis is $300,000 and the property is residential, you get a fresh deduction of about $10,909 per year.

A common misconception is that heirs “inherit” the recapture tax along with the property. They do not — the recapture from the decedent’s ownership simply disappears, and your own recapture clock starts at zero from the date you inherit.

What you should do: do not copy the prior owner’s depreciation figures onto your return; set up a brand-new schedule using your stepped-up building basis.

Full Step-Up vs. Half Step-Up

Whether your entire property steps up or only half of it depends on how it was owned. This is where many heirs miscalculate, so match your situation carefully.

If you inherit from a single owner, the whole property steps up to date-of-death value. If you co-owned or were married to the owner, the answer splits along ownership and state lines.

Joint Owners Who Were Not Spouses

If you and your sibling owned a rental 50/50 and your sibling dies, only their half steps up. Your original half keeps its old basis. So if the property is worth $400,000 at death, your sibling’s half steps up to $200,000, but your half stays at whatever you originally paid for it.

The consequence: when you later sell, you owe more tax on your “old” half than on the inherited half. Knowing this lets you plan, because a future sale price is allocated across both halves.

Married Couples in Common-Law States

In the roughly 41 common-law (non-community-property) states, when one spouse dies, only the deceased spouse’s half of jointly owned property steps up. The surviving spouse keeps their own half at the original basis. So a property worth $400,000 with a $100,000 original cost gets a basis of $250,000 — $200,000 for the stepped-up half plus $50,000 for the survivor’s unchanged half.

Married Couples in Community Property States

In the nine community property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — the rule is far more generous. Under IRC Section 1014(b)(6), when one spouse dies, both halves of community property step up to full fair market value. This is the famous “double step-up.”

So that same $400,000 property with a $100,000 original cost gets a full $400,000 basis when the first spouse dies, not $250,000. The surviving spouse could sell the next day with almost no taxable gain. A second step-up then occurs when the surviving spouse dies and the property passes to the children.

Which Situation Applies to You?

Use this quick branch to find your path, then read the matching section above.

You inherited the whole property from one person → full step-up to date-of-death value.
You already owned half and a co-owner died → only their half steps up; yours stays put.
You are a surviving spouse in a common-law state → half step-up.
You are a surviving spouse in a community property state → full double step-up.
The estate was large enough to file Form 706 → confirm whether the alternate valuation date was used.
You plan to keep renting → focus on the land/building split and a new 27.5-year schedule.
You plan to sell soon → focus on date-of-death value and Form 8949/Schedule D.

A Fully Worked Example

Let’s run the numbers end to end for a sale, because this is the math IRS publications never quite show you.

Maria inherits a single-family rental from her father, who died on April 10, 2025. He bought it in 1990 for $60,000 and had claimed $40,000 of depreciation over the years, leaving him an adjusted basis of $20,000. A retroactive appraisal sets the date-of-death value at $450,000.

Maria’s stepped-up basis: $450,000 (her father’s $20,000 adjusted basis is irrelevant).
His $40,000 of past depreciation recapture: wiped out at death.
Maria sells eight months later for $470,000, paying $30,000 in selling costs.

Her amount realized is $470,000 − $30,000 = $440,000. Her gain is $440,000 − $450,000 = a $10,000 loss. Because the property was held for investment, that loss may be deductible. Maria owes no capital gains tax and may even claim a loss — a swing of well over $100,000 compared with using her father’s old basis.

Now change one fact: Maria keeps renting it. She splits the $450,000 basis into $90,000 land and $360,000 building (a 20/80 assessor ratio). Her new annual depreciation is $360,000 ÷ 27.5 = $13,091 per year, deducted on Schedule E with Form 4562, starting fresh from April 2025.

Three Common Scenarios

Scenario 1: Sell the inherited rental right away

If you do this	Here is the tax result
Get a date-of-death appraisal at $450,000	Your basis is $450,000, locking in the step-up
Sell within months near that value	Little or no gain; possible deductible loss after selling costs
Report the sale on Form 8949 and Schedule D	Gain is automatically long-term, taxed at lower rates if any
Skip the appraisal	IRS may set basis low or at zero, taxing most of the sale price

Scenario 2: Keep renting the inherited property

If you do this	Here is the tax result
Split basis into land and building	Only the building is depreciable
Start a fresh 27.5-year schedule	New annual depreciation deduction, ignoring the prior owner’s
Make a capital improvement	Adds to basis and a separate depreciation schedule
Forget to track depreciation	Gain is understated at sale; penalties and interest can follow

Scenario 3: Surviving spouse in a community property state

If you do this	Here is the tax result
Treat the property as community property	Full double step-up to fair market value
Sell shortly after the first spouse dies	Almost no taxable gain
Hold until the second spouse dies	A second step-up for the children
Mislabel it as separate property	Only half steps up; you overpay capital gains tax

More Named Examples

James sells immediately. James inherits a duplex worth $320,000 when his mother dies in 2025. He sells it three months later for $325,000 with $20,000 in costs. His amount realized is $305,000 against a $320,000 basis, so he reports a small loss on Schedule D and owes no tax — even though his mother paid only $70,000 decades earlier.

Priya keeps renting. Priya inherits a rental valued at $500,000. The assessor shows land at 30%, so her building basis is $350,000. She begins a fresh 27.5-year schedule for $12,727 a year on Form 4562, ignoring the $200,000 her late uncle had already depreciated.

The Nguyens use community property. Mr. Nguyen dies in California owning a rental with his wife. Their original cost was $150,000; date-of-death value is $600,000. Because California is a community property state, the entire property steps up to $600,000. Mrs. Nguyen sells for $610,000 and owes tax on just $10,000.

Forms and Process Walkthrough

Several forms come into play, and using the right one at the right time keeps you out of trouble.

To establish basis, the estate’s executor may file Form 706 (the estate tax return) if the estate exceeds the $13.99 million 2025 exemption, and may issue Form 8971 with a Schedule A to report each heir’s basis. Most estates fall below the threshold and file neither, so your appraisal becomes your primary basis proof.

If you sell, report the transaction on Form 8949 and carry the totals to Schedule D of your Form 1040. Inherited property is always treated as long-term, no matter how briefly you held it, so any gain gets the lower long-term capital gains rates. For a step-by-step on the sale forms, see our guide on how to fill out Schedule D.

If you keep renting, report rental income and expenses on Schedule E, and claim depreciation on Form 4562 using your building basis over 27.5 years for residential or 39 years for commercial. The deadline for all of these is your normal April 15 filing date (April 15, 2026 for tax year 2025), or October 15 with an extension.

Deadlines, Costs, and Timing

The estate tax return, Form 706, is due nine months after the date of death, with a six-month extension available. Miss it and the estate can face penalties — and if a step-up election depends on it, you can lose valuable basis treatment.

A date-of-death appraisal typically costs $300 to $600 for a single-family rental and a few days to a couple of weeks to complete. Doing your own return is free, while a CPA handling an inherited-rental return often runs $400 to $1,000. The cost of a good appraisal is tiny next to the tax it can save.

Mistakes to Avoid

Using the decedent’s original cost as your basis — you overpay tax by ignoring the step-up.
Skipping a date-of-death appraisal — the IRS can set your basis low or at zero.
Carrying over the prior owner’s depreciation — you wrongly start with a reduced basis and lose deductions.
Depreciating the land — the IRS disallows it and assesses back taxes plus penalties.
Assuming a full step-up on jointly owned property in a common-law state — only half steps up.
Mislabeling community property as separate property — you forfeit the double step-up.
Forgetting that depreciation lowers your adjusted basis — you understate gain at sale and face penalties.
Treating inherited-property gain as short-term — it is always long-term, and you may overpay.
Letting the executor and heirs report different values — mismatched basis numbers invite an audit.

Do’s and Don’ts

Do’s

Do get a written date-of-death appraisal, because it is your defense if the IRS questions basis.
Do confirm the valuation date with the executor, because your basis must match the estate’s value.
Do split basis into land and building, because only the building can be depreciated.
Do start a fresh depreciation schedule, because the prior owner’s history does not transfer.
Do keep every improvement receipt, because improvements raise your basis and cut future gain.

Don’ts

Don’t reuse the decedent’s adjusted basis, because it produces a far higher and wrong tax bill.
Don’t depreciate the land portion, because it is never depreciable and triggers IRS adjustments.
Don’t assume your state mirrors federal rules on spousal step-up, because community property states differ.
Don’t ignore depreciation recapture on your own future ownership, because it returns when you later sell.
Don’t guess at fair market value, because an unsupported number is the weakest position in an audit.

Pros and Cons of the Stepped-Up Basis Rules

Pros

Erases the decedent’s lifetime gain, because basis resets to current value and slashes capital gains tax.
Wipes out the decedent’s depreciation recapture, because a fresh basis carries no prior depreciation.
Resets depreciation, because you get larger new deductions on a higher building basis.
Treats all gain as long-term, because inherited property always qualifies for lower rates.
Offers a double step-up for community property, because both spousal halves reset at the first death.

Cons

Requires solid valuation proof, because a missing appraisal can collapse the entire benefit.
Only half steps up in many joint-ownership cases, because the survivor’s share keeps its old basis.
A higher basis means a smaller deductible loss is rare, because gains are already minimized.
Future appreciation is fully taxable, because the reset only covers value built up before death.
State conformity varies, because not every state treats spousal property the same way.

What to Do Next

Get a qualified date-of-death appraisal of the rental, valuing it as of the day the owner died.
Ask the executor whether the estate filed Form 706 and which valuation date it used, then match it.
Decide whether you will sell or keep renting, since each path uses different forms.
If selling, prepare Form 8949 and Schedule D, treating the gain as long-term.
If renting, split your basis into land and building and start a fresh schedule on Form 4562.
Gather and store all valuation and improvement records in one place for as long as you own the property.
Call a CPA or tax attorney if the estate owes estate tax, the property crosses state lines, or co-ownership makes the step-up unclear.

FAQs

Is inherited rental property basis the same as the purchase price?

No. Your basis is the property’s fair market value on the date of death, not what the decedent paid. For tax year 2025, this stepped-up basis usually wipes out the gain that built up during their lifetime.

Do I owe tax on the decedent’s depreciation when I inherit?

No. The previous owner’s depreciation recapture is wiped out at death because your basis steps up to fair market value. Your own depreciation clock then restarts at zero from the date you inherit.

How do I prove the date-of-death value to the IRS?

A qualified appraisal valuing the property “as of” the date of death is the strongest proof. Without it, the IRS can set your basis low or at zero, taxing nearly the full sale price.

What is the alternate valuation date?

Six months after death. Under IRC Section 2032, the estate may elect to value all assets six months later, but only if it lowers both the estate’s value and the federal estate tax due.

Can I depreciate the inherited rental again?

Yes. You start a fresh 27.5-year residential schedule (39 years commercial) on your building basis, using Form 4562, regardless of how long the prior owner depreciated it.

Does the whole property step up if my spouse and I owned it?

It depends on your state. In community property states, the full property steps up at the first spouse’s death. In common-law states, generally only the deceased spouse’s half steps up.

Is gain on inherited rental property short-term or long-term?

Always long-term. Inherited property automatically qualifies for lower long-term capital gains rates, even if you sell it the day after you inherit it.

Do I need to file Form 706?

Usually no. For 2025, only estates exceeding the $13.99 million federal exemption must file Form 706. Most heirs rely on an appraisal instead of an estate tax return.

Can I deduct a loss if I sell the inherited rental?

Yes, often. Because investment property is held for profit, a loss after selling costs can be deductible. A personal residence you never rented would be treated differently.

Do states follow the federal stepped-up basis rule?

Mostly yes. Most states conform to federal Section 1014 for income tax, but community property states give a more generous full step-up at the first spouse’s death.

What happens if I keep the original owner’s old basis by mistake?

You overpay tax. Using the decedent’s lower cost basis inflates your taxable gain by the full lifetime appreciation, often costing tens of thousands of dollars you did not owe.

Does a mortgage on the property change my basis?

No. An outstanding mortgage does not reduce your stepped-up basis. Your basis is the property’s full fair market value at death, regardless of any debt still owed against it.
