Step-Up in Basis and Estate Tax Threshold Explained
When you think about passing on your wealth, whether it’s your childhood home, a beloved collection, or your investment portfolio, the details matter. You may have heard terms like “step-up in basis” or “estate tax threshold,” but what do they really mean for everyday families?
Let’s break it down in simple terms. By understanding these concepts, you’ll gain the clarity to make informed decisions about your financial legacy.
What Is Step-Up in Basis?
A step-up in basis adjusts the value of an inherited asset to its fair market value (FMV) at the time of the original owner’s death.
For example, imagine you inherit Grandma Edna’s house. She bought it for $100,000, but it’s worth $300,000 today. The “cost basis” steps up to $300,000 so if you later sell it for $350,000, you’re only taxed on $50,000 in capital gains.
Without the step-up, you’d owe tax on $250,000 in gains. That’s a big difference.
How Step-Up in Basis and Estate Tax Help Heirs
According to the Internal Revenue Service Publication 551, dated December 2024, inherited property generally gets a new cost basis based on its fair market value at the time of the original owner’s death. This means heirs aren’t taxed on the gains that happened during the original owner’s lifetime. Instead, they only pay capital gains tax on any increase in value after inheriting the asset. For example, if someone inherits a home worth $400,000 that was originally bought for $150,000, their new “stepped-up” basis is $400,000. If they sell it later for $420,000, they’re only taxed on the $20,000 difference. Additionally, the IRS states that in 2025, estates valued under $13.99 million per person are not subject to federal estate taxes. This exemption helps most families avoid the estate tax altogether. Together, the step-up in basis and the estate tax threshold protect heirs from large tax bills and help preserve inherited wealth.
Why Step-Up in Basis Matters for Inheritors
This provision significantly reduces capital gains taxes for beneficiaries. By resetting the asset’s value, it helps families preserve more of their inheritance.
Key takeaway: The step-up helps heirs save money when selling inherited property, making it a powerful estate planning tool.
2025 Estate Tax Threshold: What You Need to Know
The federal estate tax is a tax on the transfer of wealth at death. But not every estate is taxed.
- As of 2025, the federal estate tax exemption is $13.61 million per person, or $27.22 million for a married couple.
- If your estate is valued below this threshold, no federal estate tax applies.
- If your estate exceeds this amount, the excess may be taxed at rates up to 40%.
Understanding how the step-up in basis and estate tax threshold work together can help you minimize tax burdens and maximize what your heirs receive.

Step-Up in Basis in Action
Let’s break it down with a real-world comparison:
| Asset Type | Original Value | Fair Market Value at Death | Final Sale Price | Gain Taxed Before Step-Up | Gain Taxed After Step-Up |
|---|---|---|---|---|---|
| Stock | $100,000 | $150,000 | $160,000 | $60,000 | $10,000 |
| House | $200,000 | $400,000 | $450,000 | $250,000 | $50,000 |
As shown, a step-up significantly reduces taxable gains, making it easier for heirs to keep more of their inheritance.
Importance of State-Level Estate Taxes
Even if your estate avoids federal estate taxes, your state might have its own rules.
- Massachusetts and Oregon, for example, have estate tax exemptions around $1 million.
- Connecticut and New York also impose estate taxes with different thresholds.
If you live in a state with a lower exemption, your heirs could face state taxes even if they’re clear federally. That’s why it’s important to work with a local estate planner.
Real-Life Family Example
Consider the Johnson family. Mr. Johnson inherited his father’s antique car collection, originally purchased for $150,000 but worth $500,000 at the time of his death.
If Mr. Johnson’s children later sell the collection for $550,000:
- With step-up: Only $50,000 is taxed as capital gains.
- Without step-up: They’d be taxed on a $400,000 gain.
That’s the financial value of proper estate planning.
Common Misconceptions About Estate Taxes
“I’m not rich, so this doesn’t apply to me.”
False. Home values, retirement accounts, and investments add up quickly. Many middle-class families could exceed state-level thresholds without realizing it.
“Everything goes to my spouse automatically, so I don’t need a plan.”
Not always. Laws vary by state. Without an estate plan, you could unintentionally create legal complications or disputes among heirs.
Why Estate Planning Still Matters
Estate planning is more than just tax avoidance; it’s about clarity, love, and preserving family harmony.
A professional estate planner or tax advisor can help you:
- Use tools like trusts or lifetime gifts
- Strategize around federal and state taxes
- Ensure your wishes are legally protected
Planning today can prevent stress tomorrow for your loved ones.
