You’ve spent a lifetime building something worth passing on: your home, your investments, the wealth you’ve carefully accumulated over the years. But one of the most common estate planning mistakes could hand a significant portion of that inheritance straight to the IRS.
The good news? There’s a powerful tax provision baked right into the federal tax code that, when used correctly, can eliminate capital gains taxes for your heirs entirely. It’s called the step-up in basis, and understanding it is one of the most important steps you can take to protect your family’s financial future.
What Is the Capital Gains Tax and Why Should It Concern You?
Before we talk about the solution, it helps to understand the problem.
Let’s say you purchased your home decades ago for $50,000. Today, that same home is worth $450,000. The $400,000 increase in value is what the IRS calls a capital gain. If you sold the home, you could owe taxes on that gain.
Now imagine you decide to gift that home to your children while you’re still alive, thinking it will keep things simple. Here’s the costly mistake most families don’t see coming: when you gift an asset, you also transfer your original cost basis.
That means your children inherit the house and your original $50,000 basis. If they sell it for its current market value of $450,000, they face capital gains taxes on $400,000 of appreciation. Depending on their income and state of residence, that tax bill could reach tens, or even hundreds, of thousands of dollars.
There is a limited workaround called the home sale exclusion (IRC §121): if your children move into the home and live there for at least two years before selling, they may be able to exclude up to $250,000 of that gain ($500,000 for a married couple). But that requires a major lifestyle change on their part, and it doesn’t fully solve the problem for larger estates or investment properties.
There’s a far more effective strategy: the step-up in basis.
What Is the Step-Up in Basis? (IRC § 1014 Explained)
The step-up in basis is one of the most valuable tax provisions in the entire Internal Revenue Code, specifically Section 1014. And yet, many families never take advantage of it because they don’t know it exists.
Here’s how it works:
When you pass away and leave an appreciated asset to an heir, the asset’s cost basis is “stepped up“ to its fair market value on the date of your death. All the appreciation that occurred during your lifetime is effectively wiped clean for income tax purposes. As with most things in the law, exceptions apply, but they are complex, and this is the general rule.
Using the same example: you bought your home for $50,000, and it’s worth $450,000 on the date you pass away. Instead of inheriting your $50,000 basis, your children inherit the home with a new, stepped-up basis of $450,000. If they sell it the next day for that same price, their capital gain is zero. Their tax bill? Zero.
By simply allowing the asset to pass through your estate rather than gifting it early, your heirs could save a fortune in taxes. This single distinction, inheriting versus receiving a gift, can mean the difference between a legacy that thrives and one that’s diminished by an avoidable tax burden.
Which Assets Qualify for the Step-Up in Basis?
The step-up in basis applies to most capital assets, including:
- Your primary residence
- Vacation and investment properties
- Stocks and mutual funds held in a taxable brokerage account
- Collectibles and fine art
- Business interests (in many cases)
This is why it often makes more strategic sense to hold onto your most appreciated assets rather than gifting them during your lifetime. Letting them pass through your estate allows your heirs to benefit from the step-up.
What Assets Do NOT Qualify?
This is a critical distinction: not everything receives this favorable treatment.
Assets classified as “Income in Respect of a Decedent” (IRD) do not receive a step-up in basis. IRD refers to income that was earned but not yet taxed. The most common examples include:
- Traditional IRAs
- 401(k)s and 403(b)s
- Other pre-tax retirement accounts
When your heirs inherit a traditional IRA, they will owe ordinary income tax on every dollar they withdraw, just as you would have. The step-up rule does not apply to these accounts. This is why the strategy for transferring retirement accounts requires entirely different planning.
Trusts and the Step-Up in Basis
If you have a Revocable Living Trust, you’re in luck. Assets held in a revocable trust still receive the step-up in basis at death because they remain part of your taxable estate.
However, the rules can be significantly more complex and less favorable for certain types of irrevocable trusts. The treatment varies depending on how the trust is structured and funded, so it’s important to work with a qualified estate planning attorney before transferring appreciated assets into an irrevocable trust.
A Special Benefit for Married Couples in Community Property States
If you and your spouse live in a community property state, such as California, Arizona, or Washington, you may be entitled to a significant additional advantage.
In these states, when the first spouse passes away, the entire value of a community property asset receives a step-up in basis, not just the deceased spouse’s half. This “double step-up” can provide a remarkable tax benefit to the surviving spouse.
(Note: Florida is not a community property state, but understanding how other states handle this can be relevant for families with property or ties to community property jurisdictions.)
Why This Matters More Than Ever in 2026
As of 2026, the federal estate tax exemption stands at $15 million per person. This means the vast majority of American families will not owe any federal estate tax at all.
As a result, estate planning has evolved. The conversation has shifted from avoiding estate taxes to managing income taxes for heirs. And maximizing the step-up in basis is one of the most important and underutilized strategies for doing exactly that.
The key takeaway: gifting a highly appreciated asset during your lifetime can create a significant tax problem for your children. Allowing them to inherit it instead could save your family a substantial amount of money.

Frequently Asked Questions
Step-Up in Basis: Common Questions Answered
Q: What is the step-up in basis in estate planning?
The step-up in basis is a federal tax provision (IRC § 1014) that resets the cost basis of an inherited asset to its fair market value on the date of the original owner’s death. This means heirs who sell the asset shortly after inheriting it typically owe little to no capital gains tax, regardless of how much the asset appreciated during the decedent’s lifetime.
Q: How does the step-up in basis save my heirs money?
When you gift an asset during your lifetime, your heirs receive your original (often low) cost basis. If they sell the asset, they owe capital gains tax on all the appreciation. By contrast, if the asset passes through your estate, the basis resets to the current market value, potentially eliminating decades of taxable gain entirely.
Q: Do retirement accounts like IRAs get a step-up in basis?
No. Traditional IRAs, 401(k)s, and other pre-tax retirement accounts are classified as “Income in Respect of a Decedent” (IRD) and do not receive a step-up in basis. Your heirs will owe ordinary income tax on withdrawals from inherited pre-tax accounts, just as you would have. Planning for retirement account transfers requires a separate strategy.
Q: Does a Revocable Living Trust get the step-up in basis?
Yes. Assets held in a standard Revocable Living Trust are still considered part of your taxable estate, so they receive the step-up in basis at death. However, certain types of irrevocable trusts are treated differently, and the rules can be complex. It’s important to work with an estate planning attorney to understand how your specific trust is structured.
Q: Is it better to gift property to my children or let them inherit it?
In most cases, it is more tax-efficient to allow appreciated assets to pass through your estate rather than gifting them during your lifetime. Gifting transfers your original cost basis along with the asset, which can result in a large capital gains tax bill for your children when they sell. Inheriting the same property triggers the step-up in basis, which can eliminate that tax liability entirely.
Q: What assets qualify for the step-up in basis?
Most capital assets qualify, including your primary residence, vacation and investment properties, stocks and mutual funds in taxable brokerage accounts, collectibles, art, and many business interests. Assets that do not qualify include pre-tax retirement accounts (IRAs, 401(k)s) and other IRD assets.
Q: Do I need an estate planning attorney to take advantage of the step-up in basis?
While the step-up in basis applies automatically to qualifying assets that pass through your estate, working with an estate planning attorney ensures your assets are structured correctly to maximize this benefit. Mistakes — like transferring appreciated assets into certain irrevocable trusts or gifting them prematurely can inadvertently eliminate the step-up. A qualified attorney can review your current plan and identify opportunities to preserve your family’s wealth.
