Navigating the Basis Step-Up Minefield on Inherited Property

February 19, 2026

When clients come to us with questions about capital gains tax after inheriting property, one of the most common misconceptions involves the “step-up in basis.” Many Texans assume that all jointly owned property automatically receives a full step-up at death. The reality is more nuanced. Whether you receive a full or partial basis adjustment depends largely on how the property is owned and who owns it.

This article explains how the step-up in basis works for property held as joint tenants with right of survivorship (JTWROS) in Texas and why proper titling can make a significant difference in your tax outcome.

What Is a Step-Up in Basis?

The “basis” of property is generally what you paid for it. When someone dies, the tax law under Internal Revenue Code § 1014 typically adjusts the basis of property included in that person’s taxable estate to its fair market value on the date of death.

This matters because capital gains tax is calculated based on:

Sale Price – Adjusted Basis = Taxable Gain

A higher basis means less taxable gain if the property is sold later.

Joint Tenancy with Right of Survivorship — The Basics

Joint tenancy with right of survivorship is a form of ownership where:

  • Two or more people own property together, and
  • When one owner dies, their interest passes automatically to the survivor(s), outside probate.

While survivorship determines who inherits the property, it does not determine how much of the property receives a step-up in basis. That is controlled by federal tax law and depends on ownership classification.

Scenario 1: Non-Spouse Joint Tenants

If the co-owners are not married (for example, siblings, business partners, or a parent and child), only the deceased owner’s share receives a step-up.

Example

Two siblings purchase a property for $200,000 and hold title as JTWROS. Each owns 50%.

  • Value at first sibling’s death: $400,000
  • Deceased sibling’s share value: $200,000

Result:

  • Deceased sibling’s half steps up to $200,000 basis
  • Surviving sibling’s half remains at original $100,000 basis

Total new basis for survivor = $300,000, not $400,000.

If the survivor later sells for $400,000, taxable gain is $100,000.

Scenario 2: Married Couples in Texas

Texas is a community property state, which changes the analysis significantly.

If married spouses own property as community property, then at the death of the first spouse:

Both halves of the property receive a step-up in basis.

That means the survivor’s half also adjusts—even though they were already the owner of that half.

Example

Married couple purchases property for $200,000 (community property).

  • Value at first spouse’s death: $400,000

Result: Entire property basis becomes $400,000.

If the surviving spouse sells for $400,000 shortly after, there is no capital gain.

Scenario 3: Married Couple in Texas With One Spouse Owning Separate Property

Even in a community property state like Texas, a spouse can still have some separate property.  For example, anything they bring into the marriage, or any property a spouse receives after marriage by gift or inheritance, is deemed separate property.

If a married spouse owns a piece of property as separate property, and his basis in the property is $400,000. He then retitles it so that he and his wife own as joint tenants with rights of survivorship.  At the death of the husband, the property is worth $500,000.

All the property receives a step-up in basis, since the deceased spouse owned 100% of the property as his separate property, even though he retitled it as joint tenants with right of survivorship.

But what if the wife passes away first, when the property is worth $500,000?  There is no step-up in basis, as the wife didn't have a community property interest in the property.  If the husband later sells the property for $500,000, there will be a gain of $100,000 that will need to be reported.

Why Titling Matters for Estate Planning

The difference between a full and partial step-up can mean tens or hundreds of thousands of dollars in capital gains tax.

Improper titling is especially common with:

  • Brokerage accounts
  • Real estate deeds
  • Bank accounts
  • Out-of-state property
  • Assets retitled after refinancing or transfers

Even financially sophisticated individuals often assume survivorship language automatically provides optimal tax treatment. It does not.

Planning Considerations

When evaluating jointly owned property, consider:

  • Are the owners married?
  • Is the property actually community property?
  • Is survivorship language properly drafted?
  • Were contributions unequal?
  • Does estate tax inclusion differ from ownership percentage?
  • Would a trust structure produce better tax results?

These factors can change both inheritance mechanics and tax consequences. However, you have to be careful as well that when titling assets that you don't defeat the purpose of your overall estate plan. For example, you may own a parcel of real estate as your separate property, because you received that residence or tract of land as an inheritance or gift from a parent or a deceased spouse. If your intention is to pass that property to your children, and not to a second marriage spouse, then you should not consider ownership as joint tenants with right of survivorship. If you do that, then the second marriage spouse will receive the property rather than your children. You should always consult with a trusted advisor, such as your attorney, when thinking about titling of assets, especially in blended family situations.

Practical Takeaway

In Texas, a full step-up in basis is not automatic for joint tenancy property.

  • Non-spouse joint tenants generally receive only a partial step-up.
  • Married couples typically receive a full step-up only if the asset qualifies as community property.
  • Separate property will only receive a full step-up when the separate property owner passes away.
  • The exact wording of title documents can determine whether heirs save or lose significant tax benefits.

Final Thoughts

The step-up in basis is one of the most valuable tax advantages in estate planning, but it only works optimally when assets are structured correctly. Titling decisions that seem minor today can have major financial consequences for heirs later.

If you want to confirm whether your property ownership is optimized for both probate avoidance and tax efficiency, a review of your asset titles is an excellent place to start.
