Step-Up in Basis at Death: What Martinez, CA Homeowners and Heirs Need to Know

If you’ve inherited property in Martinez, California, or expect to in the future, it’s crucial to understand the step-up in basis rule and how it impacts capital gains taxes. This overlooked tax benefit could potentially save heirs thousands of dollars—but only if it’s done correctly and documented at the right time.

Let’s break it down in simple terms.

What Is the Step-Up in Basis?

The step-up in basis is a provision in U.S. tax law that resets the value (or “basis”) of an inherited property to its fair market value at the time of the owner’s death.

Here’s a Real-World Example in Martinez:

  • Your parents bought a home in Martinez in 1990 for $150,000.
  • At the time of their passing in 2024, the home is worth $950,000.
  • Thanks to the step-up in basis, your new tax basis becomes $950,000, not $150,000.
  • If you sell the home shortly afterward for $960,000, your taxable gain is only $10,000.

Without the step-up in basis, you would owe capital gains taxes on the $810,000 increase in value—a potentially massive and unnecessary tax burden.

Why So Many Families in California Miss Out

Many families miss this tax-saving opportunity simply because they don’t get an appraisal at the time of death. Later on, when heirs want to sell the property, it becomes difficult or impossible to prove what the home was worth when it was inherited.

The IRS requires proof of fair market value—and without it, you could end up paying far more in capital gains tax than necessary.

The Importance of a Timely Real Estate Appraisal

To take full advantage of the step-up in basis:

  • Get a certified real estate appraisal as soon as possible after the homeowner’s death.
  • Keep detailed records of the appraisal, property condition, and market comps.
  • Work with a local CPA or estate attorney who understands California real estate laws.

In a high-appreciation market like Martinez and the East Bay, the difference between accurate documentation and guesswork can amount to tens or even hundreds of thousands of dollars.

What If There’s No Historical Appraisal?

If you didn’t get an appraisal at the time of inheritance, it’s still worth consulting a real estate professional. In some cases, retrospective appraisals may be possible, although they are often less reliable and may be challenged by the IRS.
