What is the Step-Up in Basis for Estate Assets? (w/Examples) + FAQs

The “step-up in basis” is a U.S. tax rule that resets the value of an inherited asset to its full market price on the day the original owner passed away. This powerful provision often erases a lifetime of taxable profit for the person who inherits the asset. The primary conflict this rule addresses is a potential tax nightmare for heirs, who could otherwise owe huge sums on appreciation they never personally enjoyed. This problem is created by Internal Revenue Code (IRC) § 1014, which, without its step-up provision, would force heirs to use the original, decades-old purchase price to calculate taxes, leading to a massive and often unaffordable tax bill.

The financial impact of this rule is enormous. The U.S. government loses a significant amount of tax revenue from this provision, with one estimate from the Joint Committee on Taxation projecting nearly $42 billion in lost revenue for 2021 alone. This rule is a cornerstone of estate planning that can save families a fortune, but misunderstanding it can be incredibly costly.

The Building Blocks: Understanding the Core Concepts of Basis

To truly grasp how the step-up in basis works, you first need to understand a few key ideas. These concepts are the foundation for calculating taxes on any property you sell, whether you bought it yourself or inherited it. They are simple ideas that have huge financial consequences.

What Is “Cost Basis” and Why Is It Your Most Important Tax Number?

Cost basis is the amount of your investment in a property for tax purposes. When you buy something, the basis is usually its purchase price plus any extra costs to acquire it. This includes things like sales tax, freight charges, and legal fees. Think of it as your starting point for measuring profit.

For a house, the cost basis also includes settlement fees and money you spend on major improvements, like adding a new room. It does not include costs for getting a loan, like appraisal fees. Your basis can increase with improvements or decrease if you take tax deductions for things like depreciation.

The reason basis is so important is simple: it determines your profit when you sell. The formula is Sale Price – Adjusted Basis = Taxable Gain or Loss. An accurate basis is the only way to calculate the correct amount of tax you owe.

What Does “Fair Market Value” (FMV) Mean to the IRS?

Fair Market Value (FMV) is the price an asset would sell for on the open market. The legal definition, used by the IRS and courts, is the price a willing buyer would pay to a willing seller. This definition assumes both people have reasonable knowledge of the facts and neither is forced to buy or sell.

FMV is an objective standard based on the marketplace, not what an item might be worth to you personally. It assumes both the buyer and seller are acting in their own best interests and have time to make a good decision. This value is critical because it becomes the new starting point for an inherited asset’s basis.

The Main Event: How the Step-Up in Basis Wipes Away Taxes

The step-up in basis is one of the most generous provisions in the entire tax code. It allows wealth to pass from one generation to the next without the tax bill that typically comes with a lifetime of growth. Understanding how this works is key to preserving your family’s assets.

The Magic Eraser: How IRC § 1014 Forgives a Lifetime of Gains

The step-up in basis rule is found in IRC § 1014 of the U.S. tax code. It states that the basis of property inherited from someone who has passed away is generally reset to the asset’s Fair Market Value on the date of death. This legal maneuver effectively erases any capital gains that built up during the original owner’s life.

Imagine your mother bought stock for $10,000 many years ago. On the day she passes away, that stock is worth $150,000. When you inherit it, your new cost basis is “stepped up” to $150,000. The $140,000 of growth is never taxed.

If you sell the stock the next day for $150,000, your taxable gain is zero. This tax forgiveness is a powerful tool for transferring wealth. It is a major reason why many people hold onto their most appreciated assets until death.

The Other Side of the Coin: When a “Step-Down” in Basis Occurs

The basis adjustment at death is not always a step up. If an asset’s value has dropped below its original purchase price, the heir receives a “step-down” in basis. This can be a significant tax disadvantage for the person inheriting the property.

For example, your father bought a rental property for $500,000, but it is only worth $400,000 when he dies. Your new basis is stepped down to $400,000. The $100,000 “paper loss” your father had is gone forever.

If you later sell the property for $450,000, you must pay capital gains tax on a $50,000 gain. This is true even though the sale price is still less than what your father originally paid. This is why it is often a smart strategy to sell assets that have lost value before death to claim the tax loss.

Step-Up in Basis in the Real World: Three Common Scenarios

Abstract rules are one thing, but seeing how they apply to real-life situations makes the impact clear. Here are the three most common scenarios where the step-up in basis plays a critical role in a family’s finances.

Scenario 1: Inheriting the Family Home

The family home is often the most valuable asset a person owns, and it is a classic example of the power of the step-up in basis.

Imagine your parents bought their home in 1985 for $80,000. They lived there for 40 years, and when the last parent passes away, the home’s fair market value is appraised at $500,000. Because you inherit the home, your cost basis is stepped up to $500,000, and the $420,000 of appreciation is tax-free.

The table below shows the staggering difference this makes if you decide to sell.

Your Situation	Tax Outcome
You inherit the home and sell it for $510,000.	Your taxable gain is only $10,000 ($510,000 Sale Price – $500,000 Stepped-Up Basis).
Your parents gifted you the home before they passed, and you sell it for $510,000.	Your taxable gain is $430,000 ($510,000 Sale Price – $80,000 Original Basis).

Scenario 2: Inheriting a Stock Portfolio

Financial investments held in a regular, taxable brokerage account also receive a step-up in basis, which can save heirs a fortune in taxes.

Suppose your uncle bought 1,000 shares of a tech stock for $5 per share ($5,000 total) over two decades ago. At the time of his death, the stock is trading at $200 per share ($200,000 total). You inherit all 1,000 shares, and your new basis is automatically stepped up to $200 per share.

A special rule for inherited assets is that they are always treated as “long-term” holdings, qualifying for lower tax rates, no matter when they are sold.

Your Action	Financial Consequence
You sell all 1,000 shares one week after inheriting them for $205 per share.	Your taxable long-term capital gain is only $5,000 ($205,000 Sale Price – $200,000 Stepped-Up Basis).
Your uncle sold the shares for $205 per share the week before he passed away.	He would have triggered a taxable long-term capital gain of $200,000 ($205,000 Sale Price – $5,000 Original Basis).

Export to Sheets

This encourages a “lock-in” effect, where people avoid selling appreciated assets to prevent triggering taxes, instead holding them to pass to the next generation tax-free.

Scenario 3: Inheriting a Small Family Business

The step-up in basis also applies to private businesses, though it requires an extra step. The value of a private company is not as clear as a public stock. Therefore, the executor of the estate must hire a professional appraiser to determine the business’s fair market value.

Let’s say your mother started a local bakery with a $20,000 investment. After 30 years, the business is a town favorite. When she passes away, a business valuation expert determines the bakery is worth $750,000.

Your new basis in the business becomes $750,000. The $730,000 in growth is not subject to capital gains tax.

Event	Basis and Tax Impact
You inherit the bakery and decide to sell it a few months later for $750,000.	You owe no capital gains tax on the sale because the sale price equals your stepped-up basis.
Your mother sold the business for $750,000 right before she passed away.	She would have owed capital gains tax on a $730,000 profit.

The Rules of the Game: Which Assets Qualify and Which Do Not?

The step-up in basis is a powerful benefit, but it does not apply to everything you own. The IRS makes a clear distinction between assets that get this tax break and those that do not. Knowing the difference is one of the most important parts of smart estate planning.

The “Step-Up” List: Assets That Get the Tax Break

Most assets that you could sell for a profit, known as capital assets, are eligible for a step-up in basis. These assets get their value reset when they are included in the estate of the person who passed away. This is true even if the estate is not large enough to owe any estate tax.

Here are the most common assets that do receive a step-up in basis:

Real Estate (your home, rental properties, land)
Taxable Investment Accounts (stocks, bonds, mutual funds)
Business Interests (shares in a private company or partnership)
Tangible Personal Property (art, antiques, collectibles, jewelry)
Cryptocurrency (like Bitcoin, which the IRS treats as property)
Intellectual Property (patents and copyrights)

The “No Step-Up” List: Assets That Inherit a Tax Bill

A major category of assets is specifically excluded from the step-up rule. These are known as “Income in Respect of a Decedent” (IRD) assets. This is a technical term for money that the deceased person had earned or was entitled to, but had not yet paid income tax on.

When you inherit an IRD asset, you also inherit the tax bill. You must pay income tax on the money when you withdraw it, just as the original owner would have. The step-up in basis does not apply because these accounts already grew with a tax advantage (tax-deferred).

Here are the most common assets that do not receive a step-up in basis:

Traditional Retirement Accounts (IRAs, 401(k)s, 403(b)s)
Pensions and Annuities
Money Market Accounts and CDs
Unpaid Salary or Bonuses
Installment Sale Notes

This creates a clear strategy for retirement. It is almost always better to spend money from your IRA and 401(k) first. This preserves your appreciated stocks and real estate, which can then pass to your heirs with a step-up in basis, saving them from a large tax bill.

Gets a Step-Up in Basis	Does NOT Get a Step-Up in Basis
House, Rental Property, Land	Traditional IRA, 401(k), 403(b)
Stocks & Bonds in a Brokerage Account	Pension Plan Payouts
Shares in a Family Business	Tax-Deferred Annuities
Art, Antiques, and Collectibles	Unpaid Salary and Bonuses
Cryptocurrency	Money Market Accounts

A Tale of Two Transfers: The Critical Choice Between Gifting and Inheriting

There are two main ways to pass your property to your loved ones: giving it to them while you are alive (a gift) or leaving it to them when you pass away (an inheritance). The choice you make has massive tax consequences for the person receiving the asset. One path leads to tax savings, while the other can create a huge tax burden.

The “Carryover Basis” Trap of Lifetime Gifts

When you give someone an asset during your lifetime, the step-up in basis rule does not apply. Instead, a different rule called “carryover basis” takes effect. This rule means the person receiving the gift also gets your original cost basis.

Essentially, the recipient steps into your tax shoes. They inherit not just the asset but also the entire built-up, untaxed profit. When they eventually sell that asset, they will be the one responsible for paying capital gains tax on all the appreciation, going all the way back to when you first bought it.

This is one of the most common and expensive mistakes in estate planning. Giving away a highly appreciated asset, like a stock or house, can feel generous. However, it can unintentionally stick your loved one with a giant tax bill that could have been completely avoided.

Gifting vs. Inheriting: A Side-by-Side Comparison

The financial difference between these two transfer methods can be shocking. Let’s look at an example to see the numbers.

Imagine you own stock you bought for $50,000 that is now worth $400,000. You want to give it to your son, who plans to sell it a year later when it is worth $420,000.

Method of Transfer	Tax Outcome for Your Son
You Gift Him the Stock	His basis is your original $50,000. His taxable gain is $370,000 ($420,000 Sale Price – $50,000 Carryover Basis).
He Inherits the Stock	His basis is stepped up to the $400,000 value at your death. His taxable gain is only $20,000 ($420,000 Sale Price – $400,000 Stepped-Up Basis).

Export to Sheets

As the table shows, inheriting the stock saves your son from paying taxes on $350,000 of gain.

When Does Gifting Make Sense?

The government allows you to give away a certain amount of money or property each year without any tax issues. For 2024, you can give up to $18,000 to as many people as you want (this is the annual exclusion). For gifts above that amount, you start using up your lifetime gift and estate tax exemption, which is a massive $13.61 million per person in 2024.

For the vast majority of people, whose total estate is far below this multi-million dollar limit, the estate tax is not a concern. For them, the main goal should be preserving the step-up in basis. The best strategy is to hold onto highly appreciated assets and let them pass through inheritance. If you want to make gifts, it is much smarter to gift cash or assets that have not grown much in value.

A Tale of Two Marriages: How Your State’s Laws Affect Spousal Inheritance

For married couples, the power of the step-up in basis can change dramatically depending on where you live. The United States has two different systems for marital property: “common law” and “community property.” This geographic difference can lead to vastly different tax outcomes for a surviving spouse.

The “Half Step-Up” in Common Law States

Most states (41 of them) are common law states. In these states, if a married couple owns an appreciated asset together, like a house or a joint brokerage account, a special rule applies when the first spouse dies. Only the deceased spouse’s 50% share of the asset gets a step-up in basis. The surviving spouse’s original 50% share keeps its old, low basis.

For example, a couple in Florida (a common law state) buys stock together for $100,000. When one spouse dies, the stock is worth $500,000.

The deceased spouse’s half gets stepped up to $250,000.
The surviving spouse’s half keeps its original basis of $50,000.
The survivor’s new total basis is $300,000 ($250,000 + $50,000).

If the surviving spouse sells the stock for $500,000, they will have a taxable gain of $200,000.

The “Double Step-Up” Power in Community Property States

Nine states are community property states: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. In these states, most property acquired during a marriage is considered owned 50/50 by both spouses. This provides a huge tax advantage.

When one spouse dies in a community property state, a special rule in IRC § 1014(b)(6) kicks in. Both halves of the community property asset get a full step-up in basis to the current market value. This is often called a “double step-up”.

Let’s use the same example, but now the couple lives in California (a community property state). They buy stock for $100,000, and it is worth $500,000 when the first spouse dies.

The deceased spouse’s half gets stepped up to $250,000.
The surviving spouse’s half also gets stepped up to $250,000.
The survivor’s new total basis is $500,000.

If the surviving spouse sells the stock for $500,000, their taxable gain is zero. The double step-up completely wiped out the $400,000 of appreciation.

Navigating Complex Situations: Trusts, Life Estates, and Digital Assets

The basic rules of step-up in basis cover many situations, but things can get more complicated with advanced estate planning tools. The type of trust you use or the way you own property can change the tax outcome for your heirs. Even modern assets like cryptocurrency have specific rules you need to know.

How Trusts Change the Step-Up in Basis Rules

Trusts are a popular estate planning tool, but not all trusts are treated the same for tax purposes. The key difference is whether the trust is revocable or irrevocable.

Revocable Living Trusts: Assets you place in a revocable trust do get a step-up in basis when you pass away. This is because you keep control over the assets during your life, so the IRS considers them part of your estate at death. A revocable trust is great for avoiding probate while still preserving this important tax benefit.
Irrevocable Trusts: Assets transferred to a standard irrevocable trust generally do not get a step-up in basis. When you move an asset into an irrevocable trust, you give up control, and it is no longer considered part of your estate. Because it is not in your estate at death, it does not qualify for the basis adjustment.

This creates a conflict. Irrevocable trusts can protect assets from estate taxes, but they sacrifice the step-up in basis. With today’s very high estate tax exemption, many families find that avoiding capital gains tax is more important, making revocable trusts a better choice for passing on appreciated assets.

Life Estates: A Way to Pass on Property and Get a Step-Up

A life estate is a way to co-own property, often a house. One person (the “life tenant”) has the right to live in and use the property for their entire life. When they die, the property automatically goes to someone else (the “remainderman”).

Because the life tenant had lifetime use, the property is included in their estate for tax purposes when they die. This is great news for the remainderman. It means they inherit the property with a full step-up in basis to its fair market value at the time of the life tenant’s death.

Sometimes, a life estate can be “implied” even if it is not written in a deed. This can happen if a parent gifts a house to a child but continues to live there and pay all the bills without paying rent. The IRS may argue this was an “implied life estate,” which would pull the house back into the parent’s estate, allowing the child to get a valuable step-up in basis.

Step-Up in Basis for Modern and Unique Assets

The tax rules also apply to newer and less common types of assets.

Cryptocurrency: The IRS treats crypto like property, not cash. This means inherited cryptocurrency like Bitcoin is eligible for a step-up in basis. The heir’s new basis is the crypto’s fair market value at the exact time of the original owner’s death, which must be carefully documented.
Art and Collectibles: Valuable items like art, antiques, and coins also get a step-up in basis. The biggest challenge here is getting an accurate valuation. The IRS has strict rules and may even use its own Art Advisory Panel to review appraisals on very valuable pieces. One important catch: when you sell inherited collectibles, the profit is taxed at a special, higher maximum rate of 28%.

The Executor’s Playbook: How to Secure the Step-Up in Basis

The step-up in basis is a legal right, but it does not just happen on its own. The executor of an estate has a critical job to do. They must take specific administrative steps to properly document the new basis, and heirs must keep good records to defend it.

The Most Important Step: The “Date of Death” Appraisal

The entire step-up in basis process depends on one thing: proving the asset’s fair market value (FMV) on the date the person passed away. This is the executor’s primary responsibility.

For Public Stocks and Funds: This is easy. The value is the average of the high and low trading prices on the date of death, which is found on brokerage statements.
For Real Estate, Private Businesses, and Art: This is much harder. The executor must hire a licensed, professional appraiser to perform a formal “qualified appraisal”. Using a Zillow estimate or a real estate agent’s opinion is not enough and can be easily challenged by the IRS. The appraiser must look back at historical data to determine the value on a specific past date, which can be challenging.

The “Alternate Valuation Date”: A Special Exception

The tax code offers a safety valve if the estate’s assets drop in value right after death. Under IRC § 2032, the executor can choose to value the assets six months after the date of death instead. This is called the Alternate Valuation Date.

This choice has strict rules. It can only be used if it lowers both the total value of the estate AND the amount of estate tax owed. You cannot use it to get a higher basis if the market goes up. While it can save money on estate taxes in a falling market, it will also result in a lower stepped-up basis for the heirs.

IRS Paperwork: Understanding Form 706 and Form 8971

The paperwork required depends on the size of the estate.

Form 706 (Estate Tax Return): This form is only required for very large estates that exceed the federal estate tax exemption ($13.61 million in 2024). A common myth is that you must file Form 706 to get a step-up in basis. This is false. The step-up is automatic by law for all inherited property, whether a tax return is filed or not.
Form 8971 (Consistent Basis Reporting): If an estate is required to file Form 706, the executor has another job. They must file Form 8971 with the IRS and provide a Schedule A to each heir. This schedule officially reports the final value of the property that heir is inheriting.

This rule is called “consistent basis reporting.” It means the heir must use the value reported on Schedule A as their basis. They cannot claim a different value when they sell the asset. This ensures the IRS, the estate, and the heir are all using the same number.

Top 7 Mistakes That Can Erase Your Tax Savings

The step-up in basis is a huge benefit, but it is surprisingly easy to lose. Simple mistakes, often made with good intentions, can lead to unnecessary tax bills for your family. Here are the seven most critical errors to avoid.

The “Deathbed Gift” Giving away a highly appreciated asset right before passing away is a classic tax blunder. This act turns a tax-free inheritance into a taxable gift. The recipient gets stuck with your low original basis instead of a high stepped-up basis, creating a huge tax liability for them.
Adding a Child’s Name to the Deed Many parents put a child’s name on the title to their house to avoid probate. This is treated as a gift of half the property. When the parent dies, only their 50% share gets a step-up, while the child’s share is stuck with the old, low basis, partially defeating the purpose.
Spending from the Wrong Accounts in Retirement If you have both a taxable brokerage account and a traditional IRA, it is a mistake to sell appreciated stocks for living expenses. You should spend down the IRA first. The IRA does not get a step-up, so using it preserves your appreciated stocks for your heirs to inherit with a fresh, high basis.
Using the Wrong Kind of Trust People often assume all trusts work the same way, but they do not. A revocable living trust preserves the step-up in basis. An irrevocable trust, designed to remove assets from your estate, forfeits the step-up in basis for those assets.
Ignoring a “Step-Down” in Basis If you own an asset that has lost value, holding it until death is a mistake. The built-in tax loss will be permanently erased by the step-down in basis. It is better to sell the asset before you pass away to realize that capital loss on your own tax return.
Failing to Get an Appraisal The most critical administrative mistake is not getting a professional appraisal for assets like real estate or a private business right after death. Without this official documentation, it is nearly impossible to prove the correct stepped-up basis to the IRS years later when the asset is sold.
Gifting the Wrong Assets If you want to make lifetime gifts, give cash or assets that have not appreciated much. Gifting your most highly appreciated assets is like gifting a future tax problem to your loved ones. It is far more tax-efficient to let them inherit those specific assets instead.

Do’s and Don’ts for Maximizing the Step-Up in Basis

Navigating the rules of inheritance requires careful planning. Here are some simple do’s and don’ts for both asset owners and their heirs to ensure you get the full benefit of this powerful tax provision.

Do’s and Don’ts for Asset Owners

Do’s	Don’ts
Do keep good records of what you paid for assets and the cost of any improvements.	Don’t add your children’s names to the deed of your house as joint owners.
Do hold your most highly appreciated assets in taxable accounts or revocable trusts.	Don’t gift away your most valuable, low-basis assets just before you pass away.
Do spend down your traditional IRAs and 401(k)s first in retirement.	Don’t assume all trusts will give your heirs a step-up in basis; irrevocable trusts usually won’t.
Do talk to an estate planning attorney to structure your assets correctly.	Don’t forget to sell assets that have lost value to claim the tax loss yourself.
Do review your estate plan regularly, especially if tax laws change.	Don’t leave your executor without the information they need to track your assets’ basis.

Export to Sheets

Do’s and Don’ts for Heirs

Do’s	Don’ts
Do work with the executor to get a professional “date of death” appraisal for all real estate and private businesses immediately.	Don’t make any rash financial decisions in the first few months after inheriting.
Do keep a copy of the appraisal and any Schedule A from Form 8971 for your tax records.	Don’t rely on a Zillow estimate as proof of value for the IRS.
Do consult with a financial advisor and a CPA to understand the tax implications of your inheritance.	Don’t forget to continue paying the mortgage, taxes, and insurance on any inherited property.
Do retitle inherited assets into your name as soon as the estate process allows.	Don’t assume the step-up in basis is handled for you; confirm the new basis with the brokerage or custodian.
Do understand that you will owe capital gains tax on any appreciation that happens after the date of death.	Don’t throw away any documents related to the inheritance; you will need them when you sell.

The Great Debate: Pros and Cons of the Step-Up in Basis Rule

The step-up in basis has been part of U.S. tax law for over 100 years, but it is not without controversy. Policymakers frequently debate whether to keep, change, or eliminate it. Understanding both sides of the argument provides context for why this rule is so important and why its future is uncertain.

Pros (Arguments to Keep It)	Cons (Arguments to Repeal It)
Prevents Double Taxation: It avoids a situation where an estate pays a 40% estate tax and the heir then pays a capital gains tax on the same asset value.	Costs Billions in Lost Revenue: The government misses out on tens of billions of dollars in tax revenue each year, which could fund public services.
Administrative Simplicity: It avoids the nightmare of heirs trying to find purchase records for assets bought 50 years ago, which is often impossible.	Mainly Benefits the Wealthy: Since most wealth is concentrated, the tax savings overwhelmingly go to the highest-income households, increasing inequality.
Protects Family Farms & Businesses: It helps families continue operating a farm or business without being forced to sell it just to pay a massive tax bill.	Creates Economic “Lock-In”: It encourages people to hold onto assets for tax reasons, even if selling and reinvesting would be a better financial decision.
Encourages Long-Term Investment: Knowing this benefit exists at the end of life may encourage people to save and invest for the long term.	Enables Tax Avoidance Strategies: The ultra-wealthy can use “buy, borrow, die” strategies to live off tax-free loans secured by assets that are then sold tax-free at death to repay the loans.
Fairness for Small Estates: For the 99% of estates that owe no estate tax, it is the primary mechanism for passing on assets without a punitive tax hit.	Original Rationale Is Outdated: The original “double tax” argument is irrelevant for most estates today, as very few are large enough to pay any estate tax.

Frequently Asked Questions (FAQs)

1. What is the step-up in basis in simple terms?

Yes. It is a tax rule that resets an inherited asset’s cost basis to its market value on the owner’s date of death. This often erases the taxable gain that built up during the owner’s life.

2. Do I have to pay taxes right when I inherit something?

No. There is no federal inheritance tax paid by the person who inherits. However, six states do have a state-level inheritance tax. You only pay capital gains tax when you sell the asset for a profit.

3. Do I get a step-up in basis for an inherited IRA or 401(k)?

No. Retirement accounts do not get a step-up in basis. You inherit the tax-deferred status and must pay ordinary income tax on withdrawals, just as the original owner would have.

4. Is it better to inherit property or receive it as a gift?

Yes. From a tax standpoint, it is almost always better to inherit an appreciated asset. Inheriting gives you a step-up in basis, while a gift forces you to take the original owner’s low basis.

5. What is the difference between step-up basis and carryover basis?

Yes. Step-up basis applies to inherited assets, resetting the basis to the value at death. Carryover basis applies to gifted assets, where the recipient gets the donor’s original basis and the built-in tax liability.

6. My spouse died. Do I get a full or partial step-up on our joint home?

It depends. In the nine community property states, you get a full “double” step-up on the entire property. In the 41 common law states, you only get a step-up on the deceased spouse’s half.

7. Do assets in a living trust get a step-up in basis?

Yes, if it is a revocable living trust. Assets in a revocable trust are part of your estate and qualify for the step-up. Assets in most irrevocable trusts do not get a step-up.

8. What if the asset went down in value?

Yes. If the asset is worth less at death than the original purchase price, the basis is “stepped down” to that lower value. This erases the original owner’s potential capital loss, which is a disadvantage for the heir.

9. Do I need to file a special form with the IRS to get the step-up?

No. The step-up in basis is an automatic provision of the tax code. However, you must get an appraisal and keep records to prove the new basis if you are ever audited.

10. Can I use Zillow or a real estate agent’s estimate for a house’s value?

No. While they can be a starting point, the IRS is not required to accept them. The only valuation the IRS must accept is a formal appraisal from a certified, independent appraiser.

11. What if I can’t find the original purchase price of an old asset?

Yes. For an inherited asset, the original price does not matter; you only need the value at the date of death. For a gifted asset where the original basis is needed, you may have to reconstruct it using old records.

12. What is the “alternate valuation date”?

Yes. This allows an executor to value estate assets six months after death instead of on the date of death. It can only be used if it lowers both the estate’s value and the estate tax owed.

13. Does cryptocurrency get a step-up in basis?

Yes. The IRS treats cryptocurrency as property, so inherited crypto like Bitcoin is eligible for a step-up in basis to its fair market value at the time of death.

14. What about inherited art or collectibles?

15. Do inherited foreign assets get a step-up for U.S. tax purposes?
