Do I Owe Taxes on Inherited Property?

You just inherited a home. Maybe it's the house you grew up in. Maybe it's a property in Fremont your parents bought decades ago for a fraction of what it's worth today. And somewhere between the grief and the paperwork, someone mentions taxes — and suddenly you're terrified you're about to owe the government an enormous amount of money.

Here's the good news: most heirs in California owe far less in taxes than they expect — sometimes nothing at all. The reason is a powerful tax provision called the step up in basis — and understanding it could save your family hundreds of thousands of dollars.

What Is a Step Up in Basis?

A step up in basis refers to the readjustment of the value of an asset for tax purposes when that asset is inherited. Specifically, when someone inherits property, the asset's cost basis — the original value used to determine capital gains — is "stepped up" to its current fair market value at the time of the decedent's death.

Here's a real Fremont example that puts this in perspective.

Say your parents purchased their Fremont home in 1985 for $200,000. Over the decades, as the East Bay market grew, that home appreciated to $1,600,000 — right at today's Fremont average — at the time of their passing. If you inherit that home, your new cost basis becomes $1,600,000 — not $200,000. If you sell it shortly after for $1,600,000, you owe zero capital gains tax on the $1,400,000 in appreciation that occurred during your parents' lifetime.

That is the step up in basis — and in Fremont and across the Bay Area, where property values have climbed dramatically over decades, it is one of the most valuable tax provisions a family can benefit from.

Understanding Cost Basis

Before going further, it helps to understand what cost basis means.

Cost basis is essentially what was originally paid for an asset — the purchase price plus any additional costs associated with the acquisition, such as closing costs or improvements made over time. When an asset is sold, the owner is taxed on the difference between the sale price and the cost basis. This difference is known as a capital gain.

When you inherit an asset, you do not keep the decedent's original cost basis. Instead, the IRS allows the asset to be revalued at the time of death, giving the beneficiary an adjusted cost basis. This adjustment significantly reduces — and often eliminates — the capital gains tax burden when the beneficiary decides to sell.

The Importance of Fair Market Value

Fair market value is a crucial concept in this process. It refers to the price that an asset would sell for on the open market at the time of the decedent's death. For real estate, this is typically determined through a professional appraisal or a Broker Price Opinion from a licensed Realtor familiar with local market conditions.

This date of death valuation becomes the new cost basis for the heir. If the asset is later sold, capital gains taxes are calculated based on the difference between this new value and the eventual sale price — not the original purchase price decades ago.

Consider this Alameda County example. A parent purchased a home for $200,000 and it appreciated to $1,000,000 at the time of their death. If the heir sells the property for $1,100,000 shortly after, they pay capital gains tax only on the $100,000 difference — not on the $800,000 gain that accumulated over a lifetime of ownership.

Estate Tax vs. Capital Gains Tax

One of the most significant benefits of the step up in basis is the potential to eliminate — or dramatically reduce — capital gains tax liability on appreciated assets.

If the beneficiary sells the inherited property shortly after inheriting it, and there has been little change in value since the date of death, they may owe little or no capital gains tax. In Fremont and across Alameda County, where even modest homes have appreciated enormously over time, this can translate to savings of $200,000, $300,000 or more depending on the estate.

Compare this to what happens when an asset is gifted during someone's lifetime. In that scenario, the recipient receives the asset with a carryover basis — meaning the original cost basis of the giver transfers to the recipient. If the asset has appreciated significantly, the recipient faces a much larger tax bill when they eventually sell.

Inheriting the same asset rather than receiving it as a gift produces a dramatically different — and far more favorable — tax outcome.

Capital Gains Tax and the Step Up in Basis

These are two different taxes that apply to different situations, and it's important not to confuse them.

Estate tax is applied to the total value of a deceased person's estate before assets are distributed to heirs. In the United States, only estates exceeding $13,990,000 as of 2025 — increasing to $15,000,000 effective January 1, 2026 — are subject to federal estate tax. Most Bay Area families, even those with valuable real estate, fall well below this threshold.

Capital gains tax on the other hand is applied when an asset is sold, based on the increase in value from the time of acquisition to the time of sale. This is where the step up in basis provides its greatest benefit — by resetting the basis to fair market value at death, it minimizes or eliminates the taxable gain.

Understanding the difference between these two taxes helps families make informed decisions about when and how to sell inherited property in California.

Date of Death Valuation: Why It Matters

The date of death valuation is the foundation of the entire step up in basis calculation. It establishes the fair market value of the inherited property on the exact day the decedent passed away — and this number becomes the new cost basis for the beneficiary.

This valuation must be documented carefully and accurately. In cases involving real estate, a professional appraisal or Broker Price Opinion reflecting actual market conditions on that specific date is essential. In Fremont and the greater Bay Area, where market values can shift significantly month to month, precision matters enormously.

The executor of the estate may also elect an alternate valuation date — six months after the date of death — but only if doing so results in a lower overall estate value and a reduction in estate taxes. This option cannot be used solely to reduce capital gains taxes.

Whether the standard or alternate date is used, accurate documentation is critical. These numbers form the foundation for all future tax calculations related to the estate.

Types of Assets That Receive a Step Up in Basis

The step up in basis applies to a broad range of inherited assets, including:

Real estate — primary homes, rental properties, investment properties, and land
Stocks and bonds — publicly traded securities and mutual funds
Businesses — interests in closely held or private businesses
Collectibles — art, antiques, coins, jewelry, and similar items
Other personal property — vehicles, valuables, and items with documented worth

Assets held in a revocable living trust also receive a step up in basis upon death, as they are treated as part of the taxable estate. This is one of the reasons a properly structured living trust remains a powerful estate planning tool in California.

Assets That Do Not Receive a Step Up in Basis

Not every inherited asset qualifies for a step up in basis. These are the most common exceptions:

Retirement accounts — Traditional IRAs, 401(k)s, and similar tax-deferred accounts do not receive a step up. Beneficiaries pay ordinary income tax on distributions.
Annuities — Most non-qualified annuities pass to heirs with income tax obligations intact.
Lifetime gifts — Assets gifted during the giver's lifetime transfer with a carryover basis, not a stepped-up one.

Understanding which assets qualify and which do not is critical for smart estate administration — and for making informed decisions about whether to sell, hold, or transfer inherited assets.

Planning Strategies to Maximize the Step Up in Basis

For families working through an estate in the Bay Area, understanding these strategies can make a significant financial difference.

1. Act Quickly on Valuation The date of death valuation must be established promptly and documented accurately. Delays can create complications with tax authorities and courts. Engage a licensed appraiser or Realtor familiar with Bay Area market conditions as early as possible.

2. Hold Appreciated Assets Until Death For those still in the estate planning phase, holding appreciated assets — particularly real estate — until death allows heirs to benefit from the stepped-up basis, rather than selling during one's lifetime and triggering capital gains taxes.

3. Use a Revocable Living Trust Assets placed in a revocable living trust are still considered part of the taxable estate and therefore still receive a step up in basis. Trusts also allow for more streamlined asset transfers, often avoiding the lengthy California probate process entirely.

4. Be Cautious With Lifetime Gifting Gifting appreciated property during one's lifetime transfers the original basis — potentially creating a significant tax burden for the recipient. In most cases, inheriting the same asset produces a far better tax outcome.

5. Understand California Community Property Rules California is a community property state. When a spouse passes away, the surviving spouse typically receives a step up in basis on the entire community property — not just the deceased spouse's half. This is a significant advantage unique to community property states and is worth discussing with a qualified CPA familiar with California estate law.
