Community Property in Texas: What It Means for Your Estate Plan

If you’re married and living in Texas, community property law is already shaping what you own—whether you know it or not. It affects how your assets are characterized, what you can give away in your will, and the tax consequences your family will face when you or your spouse dies.

Full disclosure: matrimonial property was an entire semester of law school. There is a lot of ground to cover. This post isn’t going to get into all of it—but it will give you a practical overview of the issues most relevant to your estate plan, in a few minutes rather than a semester.

Texas is one of nine community property states. Understanding how these rules work—and where they intersect with your estate plan—is one of the most important things you can do to make sure your plan actually works the way you intend.

The Basic Rule: Marriage as an Economic Partnership

In Texas, when you’re married, generally every dollar either spouse earns during the marriage is community property—half yours and half your spouse’s. When those community dollars are used to purchase property—a house, a car, an investment account—the purchased item takes on that community character. Think of it like pouring community dollars out of a pitcher into whatever you’re buying. The source of the funds is what drives the characterization, not whose name is on the title.

This is an important distinction that trips up a lot of people: ownership and management are not the same thing. If only one spouse’s name is on the house deed, that house is generally treated as that spouse’s sole-management community property—meaning that, during the marriage, that spouse has the primary right to manage and control it, even though the other spouse still owns an undivided one-half community interest. Title reflects who manages the asset, not necessarily who owns it.

What Counts as Separate Property

Your separate property includes:

• Everything you owned before the marriage

• Generally, anything you received during the marriage as a gift or inheritance—property acquired through something other than the labor of either spouse

The underlying principle is that the labor of both spouses, and everything purchased with the fruits of that labor, belongs to both. Gifts and inheritances are carved out because they come from outside the marital partnership.

The Commingling Problem

Under Texas law, property owned by a married person is presumed to be community property. The burden falls on the person claiming separate property to rebut that presumption by clear and convincing evidence—a meaningful legal standard.

For some assets, that’s straightforward. A house purchased before marriage has a title that shows the acquisition date, and you can trace the source of funds. Bank accounts are a different story.

Here’s how I explain it: imagine a soft-serve ice cream cone with chocolate and vanilla swirl. If you want to pick out the vanilla, you might be able to do it right away—but let it sit on the counter for an hour and melt together, and at that point, you can no longer tell the vanilla from the chocolate. Since the law presumes the whole cone is community property (chocolate), that indistinguishable swirl is now effectively all community.

The best solution if you want to keep separate property separate: don’t commingle it in the first place. Keep inherited funds or premarital assets in a dedicated account and document the source carefully. A premarital or marital property agreement between spouses can also help by documenting what is separate from the outset—and by opting out of the default rule that income from separate property is community. 

This concern also shapes how we think about leaving assets to the next generation. When a parent leaves an inheritance outright to a child, that child has to be intentional—and disciplined—about keeping it separate from marital funds. Many people don’t think about this until it’s too late. One reason we often encourage clients to leave assets to their children in lifetime trusts, rather than outright, is that the trust provides a built-in structure for doing exactly that: the inherited assets stay in trust, the child benefits from them, but they’re never commingled with marital property in the first place. It’s a cleaner solution than asking the next generation to manage the tracing problem on their own.

A Note on Income from Separate Property

Here’s a nuance that surprises a lot of people: generally, income generated by separate property during the marriage is community property. Dividends, rent, interest—even if the underlying asset is separate, the income it produces during the marriage belongs to both spouses by default.

If you want the income from your separate property to remain separate, that requires a premarital or marital property agreement between the spouses that opts out of this default rule. If you have significant income-producing separate assets—a rental property, a brokerage account, an inherited business interest—this is worth discussing with an attorney before you assume the income is yours alone.

A Word of Caution: Community Property Has Tradeoffs

Before we get to the tax benefits of community property, it’s worth naming the other side of the ledger. Separate property that gets transmuted into community property—whether through commingling or intentional retitling—may become subject to equitable division in a divorce and, depending on who has management rights over the asset, may be exposed to the other spouse’s creditors during the marriage. That’s not a trivial consideration.

Think of it like the tradeoff in trust-based estate planning between control and creditor protection: a revocable trust gives you full control but no asset protection, while an irrevocable trust offers stronger protection at the cost of flexibility. There’s no universally right answer—the best structure depends on your circumstances and priorities. Tax considerations need not be the tail that wags the dog, but they are absolutely worth factoring in.

The goal is to make a thoughtful, intentional decision—not to drift through inertia and end up with a result you didn’t intend. That’s exactly the kind of thing a good estate planning conversation should surface.

The Step-Up in Basis: A Significant Tax Benefit of Community Property

This is where community property can be particularly valuable, and it’s worth understanding clearly.

When an asset is sold during life, capital gains tax is calculated based on the original purchase price (the tax basis). If you and your spouse bought your home in 1980 for $50,000 and it’s now worth $1 million, a sale today would generate a taxable gain of $950,000.

Here’s what changes at death: when a spouse dies, the income tax basis of community property is generally “stepped up” to the fair market value at the date of death—and that step-up can apply to both halves of the community property, not just the decedent’s half, provided at least one-half of the property is includible in the decedent’s estate.

So, if your spouse dies and the house is worth $1 million, your basis is reset to $1 million. If you sell it for $1 million the next day, you owe no capital gains tax. And when you later die, your heirs get another step-up to whatever the value is at that point.

Compare this to property held as joint tenants with right of survivorship (JTWROS), where only the decedent’s half receives a step-up. On that same $1 million house, in a simplified example, a surviving spouse holding as JTWROS would have a basis of $525,000—their original $25,000 half-basis, plus the $500,000 step-up on the decedent’s half. The difference in after-tax outcome can be substantial for long-held appreciated assets.

For assets properly characterized as community property, this step-up is a meaningful benefit. 

What Your Will Can and Can’t Do with Community Property

A will can only give away what you actually own. As a married person in Texas, you own:

• An undivided one-half interest in all community property

• 100% of your separate property

• All of this subject to your surviving spouse’s homestead rights and other statutory protections

This means you cannot validly will away your spouse’s half of community property—no matter what your documents say—so documents drafted on incorrect ownership assumptions may not operate as intended. If your estate plan was drafted without a clear understanding of how your assets are characterized under Texas law, it may not work the way you intend.

A Note on Blended Families

I’ll keep this brief, because it deserves its own post. The short version: in blended families, the intersection of community property rules and Texas intestacy law can force surviving spouses and stepchildren into an unwanted co-ownership situation that nobody planned for and nobody is happy about. If you’re in a blended family and haven’t done estate planning—or haven’t updated your plan since remarrying—please reach out. The cost of planning is a fraction of the cost of untangling things after death.

Questions Worth Asking Yourself

• Did you bring significant assets into the marriage—savings, investments, real estate, or an inheritance?

• Are those assets still in separate accounts, or have they been mixed with joint funds?

• Have you and your spouse discussed a premarital or marital property agreement?

• When did you last review your estate plan to make sure it reflects how your assets are actually titled and characterized?

If any of those questions give you pause, that’s worth a conversation. Proper characterization matters not just for estate planning purposes, but for the tax consequences your family will face down the road.
