Passing Assets to Loved Ones: Understanding the Step-Up in Cost Basis

| October 16, 2026

One of the goals of estate planning is to help loved ones receive assets as efficiently as possible. While many people focus on wills, trusts, and beneficiary designations, an often-overlooked tax benefit is the step-up in cost basis. This provision can significantly reduce capital gains taxes for heirs.

What is Cost Basis?

Cost basis is generally the original value of an asset for tax purposes. For investments, it is typically what you paid for the asset, plus certain adjustments over time.

For example, if you purchased stock for $50,000 and it later grew to $200,000, your cost basis would usually remain $50,000. If you sold the investment during your lifetime, you could owe capital gains tax on the $150,000 increase in value.

How Does a Step-Up in Basis Work?

When certain assets are inherited, the cost basis is generally adjusted to the asset's fair market value on the date of the owner's death.

Using the previous example, if the stock was worth $200,000 when inherited, the beneficiary's new cost basis may become $200,000. If they immediately sold the investment for that amount, there would generally be little or no taxable capital gain.

This adjustment can apply to a variety of assets, including stocks, mutual funds, real estate, and other investments.

Why It Matters

The step-up in basis can help preserve more wealth for the next generation by reducing or even eliminating taxes on appreciation that occurred during the original owner's lifetime.

For families with highly appreciated investments, this benefit may be significant. It can also influence decisions about whether to sell, gift, or hold certain assets as part of a broader estate planning strategy.

A Few Important Considerations

The rules surrounding inherited assets can be complex, and not all assets receive the same tax treatment. State laws, account types, and individual circumstances can affect the outcome.

Because estate and tax planning decisions should be evaluated within the context of your overall financial picture, it is important to consult with qualified tax and legal professionals before making any changes.

Final Thoughts

Passing assets to loved ones involves more than simply transferring ownership. Understanding how a step-up in cost basis works may help families make more informed decisions and potentially reduce future tax burdens. A thoughtful estate strategy can help ensure that more of what you've built is preserved for the people and causes that matter most.
