Step-Up in Basis: A Powerful Tool for Tax-Efficient Wealth Transfer

What Is a Step-Up in Basis?

If you own investments that have grown in value over the years — stocks, real estate, or other assets — there's a hidden tax bill embedded in those gains. If you sell them during your lifetime, you'll owe capital gains tax on the difference between what you paid (your "basis") and what you sell for.

But here's where it gets interesting: when you pass those assets to your heirs at death, the tax code provides what's called a "step-up in basis." This means your heirs' new cost basis becomes the fair market value of the asset on the date of your death — effectively erasing all the unrealized capital gains that accumulated during your lifetime.

For families who have built wealth over decades, this can represent tens or even hundreds of thousands of dollars in tax savings.

A Simple Example

Let's say you purchased stock 30 years ago for $50,000, and today it's worth $500,000. If you sold it during your lifetime, you'd owe capital gains tax on $450,000 of gain. At current long-term capital gains rates, that could mean a tax bill of $67,500 or more.

But if you hold that stock until death and pass it to your children, their new basis becomes $500,000. If they sell it the next day for $500,000, they owe zero in capital gains taxes. The $450,000 in gains is never taxed.

Why This Matters for Christian Families

For families who view their wealth through the lens of biblical stewardship, understanding the step-up in basis is essential for two reasons:

First, it impacts how you give during your lifetime. If you want to make a charitable gift of appreciated stock, you can donate it directly to a charity or donor-advised fund, avoid the capital gains tax yourself, and receive a tax deduction for the full market value. This is often more tax-efficient than selling the stock and donating the cash.

Second, it impacts how you transfer wealth to your heirs. Sometimes the wisest stewardship decision is to hold highly appreciated assets and let the step-up in basis eliminate the embedded tax liability for your children. This requires coordination between your estate plan and your investment strategy.

Integrating Faith and Tax Planning

Now, I want to be clear: tax planning should never be the tail that wags the dog. As a Certified Kingdom Advisor, I believe that our financial decisions should be driven by biblical principles first and tax strategy second. Romans 13:7 tells us to "render to all what is due them: tax to whom tax is due."

But being a faithful steward also means being a wise steward. Taking advantage of legal provisions in the tax code — like the step-up in basis — isn't about avoiding responsibility. It's about maximizing the resources available for your family and for Kingdom purposes.

Common Mistakes to Avoid

Here are a few things I see families get wrong when it comes to the step-up in basis:

• Selling appreciated assets unnecessarily before death. If the assets are going to heirs anyway, holding them may save significant taxes.
• Not coordinating with an estate plan. The step-up in basis applies to assets included in your estate. Joint ownership, trusts, and beneficiary designations all affect how this works.
• Ignoring the opportunity to give appreciated assets to charity. If you're going to give, giving stock instead of cash can be dramatically more tax-efficient.
• Assuming the rules won't change. Tax laws evolve, and the step-up in basis has been debated in Congress multiple times. Stay informed and plan flexibly.

Working With an Advisor Who Understands Both Worlds

The best estate and tax planning happens at the intersection of technical expertise and biblical wisdom. You need an advisor who can run the numbers and help you think through the stewardship implications of your decisions.

Proverbs 15:22 says, "Without counsel, plans fail, but with many advisers they succeed." If you haven't reviewed your estate plan and investment portfolio together with your advisor recently, now is a great time to start.

The step-up in basis is just one tool in the toolbox — but it's a powerful one. Used wisely, it can help your family transfer wealth with integrity, minimize unnecessary tax burdens, and free up more resources for the things that matter most.
