Does it matter if you close before December 31 in Flower Mound?
Yes, for three reasons. In Texas, your homestead exemption turns on whether the home is your principal residence on January 1, so a buyer who closes and moves in by December 31 can apply for the next tax year, while a January closing can cost a buyer a full year of savings. The 2026 Denton County tax bill is due January 31 and goes delinquent February 1, so the closing date decides who pays it and how it is prorated. And the calendar year you close in decides which tax year your mortgage points, property taxes, and sale gain land in.
Here is the part nobody puts on the listing: a December 31 closing is a tax-and-timing decision, not just a date on a contract. It is also a decision you should never let override a good deal. Let's walk through what actually changes.
The January 1 line: what it means for buyers
The Texas Comptroller says a home qualifies for the residence homestead exemption when it is your principal residence on January 1 of the tax year. That is the whole game for a buyer. Close and move in before the ball drops, and you are positioned to claim the exemption for the coming year. Close on January 4, and you may be waiting.
The Texas Tribune reported in October 2026 that a buyer who purchases after January 1 can apply right away if the prior owner had no exemption on the property. If the previous owner did have one, the new owner has to wait until the new year to apply for their own. On a Flower Mound home, that can mean carrying a full year of taxes without your exemption in place. Confirm how it works on your specific property with the Denton Central Appraisal District.
A few practical points that trip people up:
- Closing is not moving in. The exemption follows principal residence, so plan the move-in, utilities, and your address change around the same week.
- The application is due by April 30 of the tax year, using Comptroller form 50-114. The Comptroller says a late application can be filed up to two years after the delinquency date, but do not plan around that.
- Your driver's license address generally has to match the property. Update it early.

What happens to the 2026 tax bill at the closing table
Taxing units start mailing bills in October. In most cases the bill is due by January 31, and taxes still unpaid on February 1 are delinquent, when the tax collector adds a 6% penalty and 1% interest (Texas Comptroller). That deadline sits right on top of a late-year closing, which is why the proration matters.
TREC contract 20-19, Paragraph 13, says taxes for the current year are prorated through the Closing Date, and that if the actual bill differs from the amount prorated, the parties adjust when the statements are available. If taxes are not paid at or before closing, the buyer pays the current year's taxes. If the buyer's lender escrows taxes, the lender normally pays them.
In practice, when the 2026 bill is already out by closing, a Texas title company explains that the seller pays the whole bill and the buyer credits the seller from the closing date through the last day of the year. Here is an illustration with made-up numbers: say the 2026 bill is $24,000 and you close on December 18. The buyer's share is the 13 days from December 19 through December 31, which is $24,000 x 13 / 365, or about $855. Your title company's figure is the one that counts, and some use a different day-count method.
The takeaway: a December closing is usually clean because the bill is real. An early-year closing can pile a tax bill and a deadline into the same two weeks. If you are closing in January, ask your title officer on day one whether the 2026 bill will be paid at the table.

The tax-year effects, and the calendar risk
For buyers. The IRS says you can generally deduct points on a mortgage for your principal residence in the year you pay them, if you itemize, the points are clearly labeled as points on the settlement statement, and you meet the other conditions in IRS Topic 504. Otherwise points are deducted over the life of the loan. Whether any of that helps you depends on whether you itemize. Kiplinger puts the 2026 standard deduction for married couples filing jointly at $32,200, so a December closing only pays off when your itemized total beats it.
Property taxes you pay count toward the state and local tax (SALT) deduction. For 2026, Kiplinger reports the cap at $40,400, which begins to phase down when modified adjusted gross income passes $505,000, reduced by 30% of the excess, with a floor of $10,000. For many Northwest DFW households, that phase-down is the whole conversation. Your CPA should run it before you move a closing date for tax reasons.
For sellers. The calendar year you close in is the year the sale is reported. Texas has no state income tax, so the question is federal: a December closing puts any gain on your 2026 return, and a January closing pushes it to 2027. Our guide to capital gains when selling a Flower Mound home covers the home-sale exclusion. Run your own numbers with a CPA.
The calendar itself. December 31, 2026 is a Thursday. Friday, December 25 and Friday, January 1 are bank holidays. Federal rules require the buyer to receive the Closing Disclosure at least three business days before signing, and Sundays and federal holidays do not count in that math. For a Thursday, December 31 signing, that usually means the Closing Disclosure lands by Monday, December 28. Add year-end title and lender volume, and one missed item (an appraisal, a payoff, a repair) can push you past the line. Our post on what happens if closing gets delayed walks through the contract mechanics, and what actually happens on closing day covers the signing itself.

If you want a December 31 closing, ask five questions in the first week of your contract:
- Is the 2026 tax bill out, and who is paying it at the table?
- Does the property currently carry a homestead exemption?
- What is the lender's last day to fund, and does my rate lock cover it?
- When will the Closing Disclosure be delivered, and how?
- Is the title commitment clear, with any objections cured?
Five answers now beat a scramble on December 29.
A clean way to decide: do not trade price, inspection rights, or a thorough title review for a date. If the numbers are close, pick the better deal. If the deal is the same either way, pick the date that gets you in the home, with the exemption on file, by January 1.
Frequently Asked Questions
Can I get the Texas homestead exemption if I close on December 30?
Generally yes, if the home is your principal residence on January 1. You apply through the appraisal district by April 30 of the tax year. Plan to move in right away and update your driver's license address, since closing alone does not make it your residence.
Who pays the 2026 property tax bill if I close in December?
Under TREC contract 20-19, Paragraph 13, taxes are prorated through the Closing Date. When the bill is already available, the seller typically pays it and the buyer credits the seller from the closing date through December 31. If your lender escrows taxes, the lender normally pays the bill when it comes due.
Are mortgage points deductible in the year I close?
Often yes, if you itemize and the points are on your principal residence, clearly shown as points on the settlement statement, and meet the other IRS Topic 504 conditions. Otherwise they are deducted over the life of the loan. Ask your CPA whether itemizing beats the standard deduction for you.
What if I close in early January instead of December?
You can still buy a great home. The risk is the homestead exemption: the Texas Tribune reports that if the prior owner already had an exemption, a new owner generally waits until the next year to apply. Ask your agent to check the property's exemption status before you pick a closing date.
