If you own a brownstone in Brooklyn, a co-op in Manhattan, or a highly appreciated stock portfolio, you’ve likely watched your net worth grow significantly over the years. But with great appreciation comes a looming question: What happens to capital gains taxes when these assets are passed down to heirs?
Fortunately, the tax code features a highly generous provision known as the step-up in basis. For New York City residents, understanding how this rule works is one of the most critical elements of local estate planning. Here is a practical breakdown of how the step-up in basis works and how it can protect your family from a massive tax bill.
What is a “Step-Up in Basis”?
To understand the step-up, you first need to understand cost basis. Your cost basis is typically what you originally paid for an asset (plus the cost of any major capital improvements, in the case of real estate).
When you sell an asset during your lifetime, you pay capital gains tax on the difference between your cost basis and the sale price.
However, if you hold that asset until you pass away, the tax rules reset the board. Under Internal Revenue Code Section 1014, the cost basis of the inherited asset “steps up” to its fair market value on the date of your death.
The Bottom Line: Any appreciation that occurred during your lifetime is completely erased for tax purposes. Your heirs only owe capital gains taxes on any appreciation that happens after they inherit the property.
A Real-World NYC Example: The Brooklyn Brownstone
To see the massive financial impact of this rule, let’s look at a typical New York City scenario:
- The Purchase: In 1985, a couple purchased a brownstone in Park Slope, Brooklyn for $150,000 (their original cost basis).
- The Passing: The surviving parent passes away, leaving the home to their daughter. At the time of death, the home is appraised at $2.5 million.
- The Sale: The daughter decides to sell the home a few months later for $2.6 million.
Scenario A: Selling Without a Step-Up (Lifetime Gift)
If the parents had gifted the brownstone to their daughter while they were still alive, she would have inherited their original $150,000 cost basis (known as a carryover basis).
| Metric | Amount |
| Sale Price | $2,600,000 |
| Carryover Basis | $150,000 |
| Taxable Gain | $2,450,000 |
| Estimated Taxes Owed (Federal + NY State + NYC) | ~$800,000+ |
Scenario B: Inheriting with a Step-Up in Basis (At Death)
Because the daughter inherited the property after her parent’s death, her cost basis stepped up to the $2.5 million fair market value on the date of death.
| Metric | Amount |
| Sale Price | $2,600,000 |
| Stepped-Up Basis | $2,500,000 |
| Taxable Gain | $100,000 |
| Estimated Taxes Owed | ~$35,000 |
By waiting to pass down the property at death rather than gifting it during their lifetime, the family saved over $750,000in combined capital gains taxes.
The NYC Tax Angle: Why Local Planning Matters
The step-up in basis is incredibly valuable nationwide, but it is a absolute game-changer for New York City residents. NYC is one of the few jurisdictions in the country subject to three layers of income tax:
- Federal Capital Gains Tax: Up to 20% (plus a 3.8% Net Investment Income Tax for high earners).
- New York State Capital Gains Tax: Taxed as ordinary income, reaching up to 10.9%.
- New York City Income Tax: Up to 3.876%.
Combined, a high-income NYC beneficiary could face a tax rate of nearly 38% on capital gains. Utilizing the step-up in basis is often the single most effective way to protect family wealth from these steep local tax rates.
Crucial Rules for New York Heirs
If you have recently inherited an asset or are currently planning your estate in New York, keep these key rules in mind:
- Get a Professional Date-of-Death Appraisal: For real estate or physical assets, do not rely on websites like Zillow. You must hire a licensed appraiser to document the property’s fair market value precisely on the date of death. This appraisal is your shield if the IRS or NYS Department of Taxation and Finance ever questions your new basis.
- Holding Periods Do Not Apply: Normally, you must hold an asset for over a year to qualify for lower long-term capital gains tax rates. Inherited property is automatically treated as a long-term capital gain, meaning you can sell it immediately without facing high short-term tax rates.
- Joint Ownership Rules: New York is not a community property state. If a married couple owns a home jointly and one spouse passes away, typically only the deceased spouse’s 50% share of the property receives a step-up inbasis.
- Watch the NYS Estate Tax “Cliff”: While the federal estate tax exemption is quite high ($15 million per person in 2026), New York State’s estate tax exemption is significantly lower (~$7.16 million). If your estate exceeds this New York threshold even slightly, you risk hitting the state’s estate tax “cliff,” which can retroactively tax the entire estate.
FAQs
1. How does the step-up in basis work for inherited property in New York?
In New York, when you inherit real estate or investments, the tax “cost basis” of those assets is adjusted—or “stepped up”—to their fair market value on the date of the deceased owner’s death. This means if you sell the inherited asset shortly after inheriting it, you will owe zero capital gains taxes on any appreciation that occurred during the original owner’s lifetime.
2. Why this matters for NYC residents:
If you inherit a family brownstone in Brooklyn or a co-op in Manhattan that was purchased decades ago for a fraction of today’s value, the step-up in basis eliminates federal, New York State, and NYC local capital gains taxes on millions of dollars of appreciation. Heirs only owe taxes on any appreciation that occurs after the date of death.
3. Do you pay capital gains tax on inherited property immediately in NY?
No. Inheriting a property does not trigger an immediate capital gains tax in New York. You only trigger capital gains tax if and when you decide to sell the property.
If you sell the property, your taxable gain is calculated using the stepped-up basis (value on the date of death) rather than what the deceased originally paid. Furthermore, the IRS automatically treats inherited property as a “long-term” holding, meaning even if you sell it a week after inheriting it, you qualify for lower long-term capital gains tax rates instead of high short-term ordinary income rates.
4. What is the risk of gifting my NYC home to my children before I die?
Gifting your home to your children during your lifetime strips them of the step-up in basis. When you gift a property, the children receive a “carryover basis” (your original purchase price). When they eventually sell the home, they will owe massive federal, state, and city capital gains taxes on all the appreciation since you bought it.
Example:
- If you gift the home: Your children inherit your 1990 purchase price of $200,000. If they sell it for $2 million, they will owe capital gains tax on $1.8 million of profit.
- If they inherit it at death: Their basis steps up to $2 million. If they sell it for $2 million, they owe $0 in capital gains tax.
5. How does a married couple get a step-up in basis on jointly owned NYC property?
Because New York is a “common law” (non-community property) state, if a married couple owns a home jointly with rights of survivorship, only the deceased spouse’s 50% share of the property receives a step-up in basis when they pass away.
The surviving spouse’s own 50% share retains its original cost basis. If the surviving spouse later sells the property, their new cost basis is a “hybrid” calculation: half of their original purchase basis plus half of the fair market value on the date of their spouse’s death.
Note: Married couples can work with a New York estate planning attorney to utilize strategies to maximize basis adjustment strategies depending on their financial situation.
6. What is the New York estate tax “cliff” and how does it impact inheritance?
While the step-up in basis saves heirs from capital gains taxes, high-value estates in NYC must still watch out for the New York State estate tax. In 2026, the NYS estate tax exemption is $7.35 million. Under New York’s unique “cliff” rule, if an estate exceeds this exemption threshold by more than 5% (over $7,717,500), the entire exemption is retroactively wiped out.
When this happens, New York taxes the entire estate from dollar one, resulting in a state tax bill that can easily reach hundreds of thousands of dollars on a modest overage. Heirs still get the capital gains step-up in basis, but the estate itself will face heavy taxation before distribution. Proper trust planning is essential for NYC homeowners to avoid falling off this tax cliff.
Protect Your Legacy with Smart Planning
The temptation to sign a deed over to your children while you are still alive to “get it over with” is incredibly common. However, doing so can strip your heirs of their greatest tax advantage.
Before making any lifetime transfers of real estate or highly appreciated stocks, consult with a qualified local estate planning attorney. They can help you structure your estate—potentially using trusts or life estate deeds—to ensure your family receives the full benefit of a stepped-up basis while avoiding unnecessary probate and tax exposure.
