Let me save you a little holiday heartbreak. If you filed for divorce this fall, or you are about to, you are almost certainly still going to be married when the ball drops on New Year’s Eve. Texas makes you wait at least 60 days after filing before a judge can sign anything, and between court calendars and everybody’s holiday schedules, “let’s just get it done by Christmas” is a wish for Santa, not a plan.
Here is why that matters for the house. The IRS does not care how you feel about your spouse. It cares about one day: December 31. And that one day can change how much tax you owe when the house sells, who gets to claim what, and even which year your sale counts in.
This is the fourth post in my divorce and the house series. If you are new here, catch up on who keeps it, who sells, and how to handle it without losing your mind, whether to sell before, during, or after the divorce, and why your name off the deed does not mean your name off the mortgage. Today we are talking taxes and timing. Fair warning: I am a real estate broker, not a CPA. My job is to make sure you walk into your CPA’s office with the right questions. Theirs is to answer them.
1. December 31 is the day the IRS takes attendance
Your marital status on the last day of the year is your marital status for the whole year. Divorce final on December 31? You are single for all of 2026, tax-wise. Divorce final on January 2? Congratulations, you were married for every single day of 2026, including the eleven months you spent not speaking to each other.
There is no partial credit. No prorating. The IRS takes attendance once, on New Year’s Eve, and whoever is standing there is who you are.
2. Still married means you pick: jointly or separately
If you are still married on December 31, you have two choices for 2026: Married Filing Jointly or Married Filing Separately. Filing jointly often costs less in tax overall. But a joint return takes two signatures, and here is the part nobody puts in the brochure: when you both sign a joint return, you are each on the hook for the whole tax bill on it. Sound familiar? It is the mortgage problem all over again, just with the IRS instead of the bank.
Filing separately keeps your tax life separate, but it usually costs more and closes the door on some credits and deductions. Which one wins for your family is a math problem for your CPA, and possibly a negotiating point for your attorneys. Just do not assume your soon-to-be-ex is going to cheerfully sign anything in April.
3. The “considered unmarried” door closed on July 1
There is one escape hatch. The IRS will treat you as unmarried, which can let you file as Head of Household, if your spouse did not live in your home for the last six months of the year, you paid more than half the cost of keeping up that home, and it was the main home of your child for more than half the year. There is more fine print, but that is the heart of it.
Now do the math on “the last six months of the year.” That clock started July 1. If your spouse moved out in July or later, this door is already closed for 2026. If they moved out before July and the kids live with you, ask your CPA about it before you file anything.

4. $500,000, $250,000, and the clock that is ticking
When you sell a home you have owned and lived in for at least two of the last five years, a big chunk of the profit can be tax-free. Up to $500,000 on a joint return when you both qualify, or up to $250,000 each when you file separately. In the Katy neighborhoods where folks bought ten or fifteen years ago, that is not a small number.
Here is the trap: the spouse who moved out has a clock running. Once you have been out of the house for more than three years, you no longer meet that two-out-of-five test on your own. There is a rule that can protect the spouse who moved out when the other spouse keeps living there under the divorce or separation paperwork, which is one more reason the house belongs in the conversation while the decree is being written, not after. Bring it up with your attorney and your CPA. Do not let it sit in a drawer.
5. Your closing date decides which tax year the sale lands in
If the house is going on the market, look at the calendar. A closing on December 30 is a 2026 sale. A closing on January 4 is a 2027 sale. Same house, same buyer, same check, and potentially a very different tax picture depending on whether you are married, divorced, filing jointly, or filing separately in that year.
And yes, you can sell a house in Katy over the holidays. The buyers out looking in December are not browsing for fun. Many are relocating for a January start date with their financing lined up, and they are not tripping over a hundred other listings. It is a short, serious season. If landing the sale in a specific tax year matters for your situation, plan backward from the closing date with your CPA, and I will guide you on what it takes to hit it.

6. The 2026 property tax bill is already on the kitchen counter
Texas property tax bills go out in the fall and are due by January 31. So right now, in the middle of your divorce, there is a 2026 tax bill on that house. Who is paying it? If your mortgage has an escrow account, the lender pays it out of escrow, which just moves the question to whose money is sitting in that escrow account.
Same goes for the mortgage interest. The year-end Form 1098 from your lender often lists only one borrower, but that does not automatically settle who gets to deduct what. Who paid it, from whose account, and what the decree says all matter. Write it down. Get it in the agreement. “We’ll figure it out at tax time” is how two grown adults end up fighting over a deduction in March.

7. Buying out your spouse is usually not a taxable sale, but the history comes with the house
If one of you keeps the house and buys the other out, good news: transfers between spouses as part of a divorce generally are not taxable sales. No tax bill just because the deed changed hands.
But here is the catch. The spouse keeping the house also keeps its tax history, starting with what you originally paid for it. If you bought in Cinco Ranch in 2010 and the value has doubled since, all that built-up gain is now one person’s future tax question instead of two people’s. And when that spouse eventually sells, they may only have a single $250,000 exclusion to cover it. Keeping the house is not just keeping the house. It is keeping the gain. Make sure the buyout number accounts for that before anyone shakes on it.
The bottom line
You are probably going to be married on New Year’s Eve. That is not a tragedy. It is just a fact, and facts are something you can plan around. Know what December 31 means for your filing status, watch the two-out-of-five clock, pick your closing date on purpose, and get the property tax bill and the buyout math in writing.

Frequently Asked Questions
Yes. If you are still married on December 31, the IRS considers you married for the entire year. A divorce that becomes final in January does not change your status for the year before.
Texas law says a judge cannot grant a divorce until at least 60 days after the petition is filed, except in certain family violence cases. That is the minimum. Scheduling, paperwork, and any disagreements usually make it longer.
If you are still married on December 31, you can file jointly, but both spouses have to agree and sign, and both are responsible for the full tax on that return. Your CPA can compare joint and separate filing for your situation.
If you owned and lived in the home for at least two of the last five years, up to $500,000 of gain can be excluded on a joint return when you both qualify, or up to $250,000 each on separate returns. The spouse who moved out should watch the timing, and a CPA should confirm the numbers.
Transfers between spouses as part of a divorce generally are not taxable sales. But the spouse who keeps the house also keeps its original purchase price for tax purposes, so the built-up gain becomes their future tax question when they sell.
It depends on your filing status and the size of your gain. The closing date decides which tax year the sale counts in, so plan the date on purpose with your CPA instead of letting the calendar decide for you.
