What Does the Stepped-Up Basis Mean for Your Tax Bill?

Here is the concept in plain terms. When you buy a house, your “cost basis” for tax purposes is generally what you paid for it. When you inherit a house, the rule works differently: your cost basis resets, or “steps up,” to the property’s fair market value on the date of the original owner’s death, not what they paid for it years or decades earlier. This matters enormously, because capital gains tax is calculated on the difference between your basis and your eventual sale price. If your parent bought a Plano home in 1995 for $140,000 and it is worth $520,000 today, you do not inherit their original $140,000 basis. Your basis becomes approximately $520,000, the value at the date of death. If you sell for close to that amount, there is little to no taxable gain, even though the home appreciated enormously over the decades your parent owned it.

The stepped-up basis is the single most important thing to understand before you do anything else with an inherited Plano property, and it is also the piece most heirs have never heard explained clearly. This federal rule, established under the Internal Revenue Code, applies regardless of what state the property is in. What changes state to state is whether there is an additional state-level tax on top of it, which is where Texas becomes genuinely good news.

Greatness is demonstrated, not declared. On a topic like this, that means giving you the accurate mechanism early, in plain language, instead of a vague reassurance that leaves you still worried.

What Texas does and does not tax

Texas removes two layers of tax exposure that heirs in many other states have to think through. First, Texas has no state inheritance tax. Texas repealed its inheritance tax in 2015, so heirs here do not owe a state-level tax simply for inheriting property, separate from any federal question (Texas Comptroller of Public Accounts). Second, Texas has no state income tax, which means there is no state-level capital gains tax on top of any federal gain either. Combined with the stepped-up basis, this is why the realistic tax picture for most heirs selling a Plano house is far simpler, and far less costly, than people initially assume.

There is one more figure worth knowing, mostly so you can set it aside rather than dwell on it: the 2026 federal estate tax exemption is $15 million per person, $30 million for a married couple. That threshold is simply irrelevant for the overwhelming majority of families going through this. Unless the estate as a whole is worth an amount most people will never personally encounter, federal estate tax is not something you need to plan around (U.S. Internal Revenue Service, federal estate tax exemption figures, 2026).

What this does not replace

None of this is a substitute for your CPA or probate attorney’s specific read on your situation. Every estate has its own wrinkles: whether the property was held in a trust, whether there were multiple owners, whether improvements were made after the date of death, whether you are one of several heirs splitting proceeds. We always frame this as general, educational information, not tax or legal advice, and we say plainly: talk to your CPA before you file anything, and your probate attorney if there is any question about the estate itself.

How Does Value Now Compare to the Stepped-Up Basis?

The clearest way to see why most heirs owe little or nothing is to look at a few realistic scenarios side by side. These are illustrative examples built around plausible Plano price points and typical holding periods, not a quote for your specific property, since your basis depends on your loved one’s actual date of death and a formal valuation as of that date, not an estimate months or years later.

A few things matter in reading this table honestly. First, selling costs, typically 7 to 8% of the sale price between commission, title, and closing costs, reduce the net gain further, and in the first scenario can absorb the entire taxable gain. Second, any capital improvements you make to the home after inheriting it, a new roof, a renovated kitchen, get added to your basis, which further reduces gain when you sell. Third, the longer you hold the property after the date of death and the more the market moves, the larger the gap between your stepped-up basis and your eventual sale price can grow, which is why heirs weighing whether to sell quickly or wait often ask us for a real, current value first rather than guessing.

None of this is tax advice. It is meant to show the mechanism, not to calculate your number. Your CPA needs your actual date-of-death valuation and your actual sale price to give you a real figure.

When Can You Actually List an Inherited House in Probate?

Taxes are only half the picture. The other question heirs ask early is when they are actually allowed to list the house, which depends on the probate process, not the tax rule. In Texas, most estates move through Independent Administration, which lets the court-appointed executor list and sell real property once Letters Testamentary are issued, commonly four to eight weeks after the probate application is filed depending on the court’s hearing schedule, without needing separate court approval for that specific sale, provided the will grants power of sale or the heirs have agreed to it (Texas Estates Code §§402.002, 402.052; or §401.006 when the heirs agree in place of will language). If the will names co-executors, which is common when several siblings inherit together, Texas law generally requires them to act jointly on a sale unless the will says otherwise, so agreement among co-executors matters before a listing goes out.

The full estate, distributing remaining assets, resolving creditor claims, filing the final accounting, commonly takes four to eight months to close in full, but the house itself is often under contract well before that finish line.

If you are still waiting on Letters Testamentary, are not sure whether your estate is an Independent or Dependent Administration, or are not sure whether all co-executors have agreed to a sale, that is exactly the kind of question worth a short call before you assume you are stuck waiting. Once you hold Letters Testamentary with the proper authority in place, you can typically move forward with listing a Plano inherited home, starting with a real number from our Plano home value guide, and the tax questions above become relevant at the point you actually sell, not before.

If there is no probate at all

Not every inherited Plano house goes through a full probate process. If the property passed via a transfer-on-death deed, a living trust, or joint ownership with right of survivorship, the transfer of title may already be resolved, and you may be able to list sooner than a traditional probate timeline would suggest. If you are not sure which situation applies to you, that is exactly the kind of question worth a short call before you assume you are stuck waiting.

How Do You Sell an Inherited House From Out of State?

A large share of the inherited-property sales we handle involve heirs who do not live in Texas. A parent or grandparent lived in Plano for decades, the adult children scattered to Colorado, California, or the East Coast, and now someone has to manage a house, and a sale, from a distance. This is common enough that we have built our process around it, not around the assumption that you can be here in person for every step. A Dallas-area probate attorney regularly refers estate and probate sales her way for exactly this reason: out-of-state heirs need boots on the ground they can trust, someone local who over-communicates and handles the property in person.

What “boots on the ground” actually looks like

In practice, that means we walk the property and send you a straightforward, honest assessment of what it needs, coordinate a locksmith, cleanout crew, or handyman without you managing three separate vendors from out of state, handle showings and offer negotiation entirely by phone and email, and coordinate with the title company and your probate attorney or CPA so your paperwork is in order before you are asked for it. You stay in control of every decision. You simply are not required to be physically present for the ones that do not need you there.

Remote closing is normal, not an exception

Texas closings routinely happen with an out-of-state seller signing through a mobile notary or via mail-away closing documents, coordinated by the title company. The seller’s disclosure obligations and standard closing paperwork are the same regardless of where you are signing from (Texas Real Estate Commission, seller disclosure and closing requirements). Knowing that upfront tends to remove one more unknown from a process that already has enough of them.

How Do You Price and Prepare an Inherited Plano Home?

An inherited home, especially a parent’s or grandparent’s longtime house, often has not been updated in years, and that is completely normal, not a problem to apologize for. The honest approach is to price it for what it is, a home with real deferred maintenance and dated finishes, rather than dress it up as something it is not. Homes in the Collin County portion of Plano carry a combined property tax rate of approximately 1.71% (City of Plano; Collin County; Plano ISD, FY2025-26), which is a number worth having ready for any buyer’s monthly-payment math, and it is also a detail we factor into pricing conversations, since buyers weighing an inherited home against a newer, updated listing are doing that math too.

We also coordinate the practical side that inherited-property sales almost always involve: a cleanout of years or decades of belongings, minor repairs that materially affect a sale price like a roof or foundation issue, and a straightforward conversation about whether it makes more sense to invest in a few targeted repairs or sell as-is and let the price reflect the home’s condition. You are not expected to make an inherited house look like a model home. You are expected to make one clear decision, sell as-is or make targeted repairs, and we will give you the real numbers behind each option so that decision is not a guess.

If you are the executor of an estate rather than a direct heir, you also have a fiduciary duty to sell for a fair, defensible price, not simply the first offer that arrives (Texas Real Estate Commission, seller disclosure and agency guidance). A documented comparative market analysis and a normal marketing period protect you in that role.

Plano’s homeownership rate of 61.4% (U.S. Census Bureau, ACS 2024) is a reminder that most eventual buyers of an inherited home are owner-occupants doing their own monthly-payment math, not just investors, so a fairly priced, honestly disclosed home draws a wider, more competitive buyer pool. See our home value guide for how that valuation process works in more detail.
