When planning your financial legacy, one tax concept can have a significant impact on your heirs: stepped-up basis. Though often labeled a “loophole,” this long-standing tax rule is perfectly legal—and potentially very beneficial.
While the stepped-up basis rule remains in effect today, it continues to face scrutiny in Washington. Several tax reform proposals have targeted it for potential repeal or modification—changes that could significantly impact your estate strategy and long-term planning.
Understanding how the stepped-up basis loophole works is crucial to minimizing your heirs’ capital gains tax exposure, both legally and efficiently. This guide walks you through what the loophole is, how it works, and what smart estate planning strategies you can use to adapt.
What Is a “Stepped-Up” Basis?
When someone inherits an asset, like real estate, stocks, or a business, the IRS allows them to “step up” the asset’s cost basis to its fair market value on the date of the original owner’s death.
Why Does This Matter?
Capital gains tax is calculated based on the difference between what you paid for an asset (the basis) and what you sell it for. A stepped-up basis reduces the taxable gain significantly for the person inheriting the asset.
Simple Example
Let’s say your mother bought a rental property for $200,000 in 1990. By the time she passes away in 2025, the property is worth $900,000. If you inherit the property, your basis is now $900,000. If you sell it soon after for $910,000, you only pay capital gains tax on inherited property of $10,000.
Without the step-up, your gain would have been $710,000.
>> Important twist: Basis can also step down if the fair market value at death is lower than the decedent’s original basis.
Why Is It Called a “Loophole”?
While stepped-up basis is not illegal or shady in any way, it’s often called a loophole because:
- Unrealized gains go untaxed: Wealth that has appreciated over time avoids capital gains taxes entirely upon death.
- High-income families benefit most: Households with large portfolios or valuable real estate gain the most.
- Revenue loss to the government: Some estimates suggest that the U.S. Treasury loses over $40 billion annually due to this provision.
That said, this rule also simplifies recordkeeping, eases tax burdens on grieving families, and supports multi-generational wealth planning, which many argue are legitimate goals. The stepped-up basis loophole remains one of the most powerful and contentious tax planning tools available to individuals and families seeking to preserve their wealth.
Who Benefits from a Stepped-Up Basis?
While it’s easy to think of billionaires passing down stock empires, this tax rule also affects everyday families.
Common Examples:
- A parent leaves a family home to their children.
- Long-held investment accounts, with decades of growth, are inherited.
- A small business is passed to the next generation.
In all these cases, the step-up in basis can reduce or eliminate capital gains tax that would otherwise be owed if those assets were sold.
For families in Maryland or D.C., it’s worth noting that while the federal rule applies, state-level estate or inheritance taxes can still impact what heirs owe.
Inherited vs. Gifted Assets
One of the most critical tax planning strategies is understanding the difference between inheritances and gifts. How you transfer assets has significant tax consequences.| Transaction Type | Basis Adjustment | Tax Impact |
|---|---|---|
| Inheritance | Stepped up to market value | Potentially no capital gains tax if sold soon after death of original owner |
| Lifetime gift | Carries the original basis | Higher risk of capital gains tax when sold |
Important Tip: Giving appreciated assets during your lifetime may unintentionally pass along a significant tax burden. Talk to a fee-only financial advisor before making significant gifts.
Paperwork reminder: If a federal estate tax return is required, the estate must provide heirs with consistent basis information. This ensures the IRS and heirs are working from the same numbers.
Spouses, Joint Ownership & Community Property
How much of an asset steps up depends on ownership and state law:
- Community property states (e.g., CA, TX, AZ, WA): both halves of the property generally receive a full step-up at the first spouse’s death.
- Common-law states: typically only the deceased spouse’s share receives a step-up.
This difference can mean thousands, or millions, in future tax savings.
What About Assets in Trusts?
Think “estate inclusion”:
- If the asset is included in the taxable estate (like those in revocable or certain grantor trusts), it usually qualifies for a step-up.
- If it’s excluded (like assets in many irrevocable trusts), it typically won’t.
Retirement Accounts ≠ Step-Up
IRAs, 401(k)s, and similar retirement accounts do not receive a step-up in basis. Instead:
- Traditional accounts are taxed as income when withdrawn by heirs.
- Roth accounts can be tax-free if distribution rules are met.
- Under current rules, many non-spouse heirs must take annual required minimum distributions (RMDs) and empty the account within 10 years, unless they qualify for exceptions.
The 6-Month “Alternate Valuation Date”
Executors can elect to value assets six months after death instead of the date of death, only if:
- It reduces the overall value of the estate, and
- It reduces the estate tax owed.
Assets sold within those six months use their sale price instead.
Recordkeeping Your Heirs Will Thank You For
- Get a professional appraisal shortly after the date of death for real estate.
- Save brokerage statements for investment accounts.
- Keep all basis records consistent with any estate tax return filed.
Rental property note: Depreciation claimed during the original owner’s life is not “recaptured” at death. Heirs can begin new depreciation schedules based on the stepped-up basis.
Why Some Want to Change It
Several tax policy proposals in recent years have targeted the stepped-up basis. The main arguments for reform include:
- Equity: Critics say it gives wealthy families an unfair advantage.
- Revenue: Ending the rule could result in billions of dollars for the federal budget.
- Economic behavior: The rule may discourage the sale or diversification of assets, creating economic inefficiencies.
Biden’s 2021 Proposal (For Context)
While not passed, a proposal included:
- Triggering capital gains tax at death on unrealized gains above $1 million.
- Carve-outs for family-owned businesses and farms.
- Deferrals for illiquid assets.
Nothing is final, but future legislation could affect how you plan for your legacy.
What Happens If The Loophole Is Repealed?
If the step-up is eliminated or reduced, families may face new challenges:
- Capital gains tax at death could become the norm.
- Asset valuations would be required at the time of death, even for long-held property or investments.
- Cash flow issues could arise if taxes are owed but the asset isn’t sold.
This would create a new layer of complexity in estate planning.
Proactive Steps to Consider
Whether you’re actively estate planning or simply building your nest egg, here are steps to help protect your family:
1. Re-Evaluate Your Gifting Strategy
Before gifting appreciated assets, it’s important to understand the potential tax consequences. Consider consulting a financial professional to evaluate the tax implications of making lifetime gifts.
2. Update Your Estate Plan
Review your will, trusts, and asset titles with a professional. Ensure your plan reflects current laws and can adapt to future changes.
3. Consider a Trust Structure
Some trust types may still offer stepped-up basis benefits, depending on their structure. For example:
- Grantor trusts: Assets may still be included in your estate, thereby qualifying for a step-up in basis.
- Irrevocable trusts: Typically remove assets from your estate, potentially resulting in the loss of the step-up.
4. Keep Detailed Records
Ensure your heirs can verify the value of assets. Appraisals and statements can help establish the basis after inheritance.
Should You Wait and See?
It’s tempting to delay action until the law changes. However, proactive planning can still provide you with flexibility.
- Create a “dual-path” plan: Prepare for current law while leaving room to pivot.
- Stay informed: Tax laws evolve. Partnering with a fiduciary financial advisor helps you make informed decisions.
- Communicate with heirs: Make sure loved ones understand your intentions—and the financial logistics that come with inheriting assets.

Estate & Inheritance Taxes in the DMV
Maryland
- Estate tax threshold (2025): $5 million
- Rate: Up to 16% on amounts above the threshold
- Inheritance tax: 10% on most transfers to non-immediate family (spouses, children, parents, siblings, and certain others are exempt)
District of Columbia
- Estate tax threshold (2025): $4,710,000
- Rate: Progressive, up to 16%
- No inheritance tax
- No state-level estate or inheritance tax
Why it matters even with a federal step-up:
- Federal law controls the step-up in basis, but state-level taxes are separate and can significantly impact what heirs actually receive.
- Even if your estate avoids federal estate tax, you could still owe state-level taxes if your assets exceed local thresholds.
- Strategies like lifetime gifting, trust structures, or charitable bequests can help mitigate both federal and state liabilities.
Local planning tip: DMV residents often have multi-state connections (e.g., a home in Virginia, a rental in Maryland). Work with a financial planner who understands the cross-border estate tax rules so you can minimize tax exposure on all fronts.
Frequently asked questions
1. What is the 6-month rule for stepped-up basis?
It refers to an alternate valuation date used for estate tax purposes. Executors can elect to value assets six months after death if it reduces both the estate’s value and tax liability.
2. What are the exceptions to stepped-up basis at death?
While most inherited assets get a step-up in basis, there are several exceptions to be aware of:
- Assets in irrevocable trusts that are not included in the decedent’s estate typically do not qualify for a step-up.
- Gifts made during life retain a carryover basis (no step-up).
- Foreign property, or property owned outside the U.S., may not qualify depending on the ownership structure and the tax treaty status.
- Income in Respect of a Decedent (IRD) assets — such as traditional IRAs, 401(k)s, or deferred compensation — do not get a step-up because they haven’t been taxed yet. These are taxed as ordinary income to the beneficiary when withdrawn.
- Joint tenancy with rights of survivorship (for married couples) may result in only a partial step-up, depending on state law and ownership structure.
Always check with a financial advisor or tax professional, especially when trusts or non-standard assets are involved.
3. How does the IRS verify the cost basis of real estate?
The IRS expects you (or your heirs) to provide reasonable documentation to support the claimed basis. Here’s how cost basis is typically verified:
- Appraisals: For inherited property, a certified appraisal as of the date of death (or 6-month alternate valuation date) is the gold standard.
- Tax assessor records: These may be used to estimate market value, although they are not always accurate.
- Comparables (comps): Sales of similar nearby properties at the time of death can support fair market value (FMV) estimates.
- Broker price opinions or CMA (Comparative Market Analysis): Sometimes used for lower-value properties.
Tip: It’s a smart move to proactively get an appraisal shortly after inheriting real estate to avoid future disputes or confusion. It is also smart to keep records of any improvements made to the property, which could increase your cost basis.
4. Do inherited IRAs receive a step-up basis?
No. Tax rules for inherited retirement accounts follow income-tax rules, not capital-gains rules.
5. Does a revocable living trust affect step-up in basis?
No. Assets in a revocable trust are included in your estate and do receive a step-up in basis.
6. If I add my child to my deed now, will they get a step-up later?
Not on the portion you’ve already gifted. That share keeps your original basis, which could mean higher taxes for them.
7. Is stepped-up basis the same in all states?
The federal rule is uniform, but states like Maryland and D.C. have their own estate or inheritance taxes that affect overall outcomes.
In Summary: What You Need to Know
- Stepped-up basis resets the cost basis of inherited assets to their value at the time of death, often eliminating capital gains tax.
- It’s perfectly legal—but increasingly under scrutiny.
- If you plan to leave assets to heirs, understand how this rule works—and how to prepare if it changes.
- Work with a team that monitors tax law, strategizes thoughtfully, and consistently prioritizes your goals.
