If your property taxes went unpaid on February 1 and the penalty notices are stacking up, you’re not alone and you haven’t lost the house yet. But Texas property taxes are some of the highest in the country, the penalty-and-interest schedule is steep and front-loaded, and the taxing units have a powerful tool most homeowners underestimate: a statutory lien that attaches to your home on January 1 every year, and a judicial path that ends with a sheriff selling the property on the courthouse steps.
This guide walks through what actually happens when you fall behind — the 2026 penalty math, how fast the county can really sell, and the realistic menu of options: paying off or getting on an installment plan, the over-65/disabled deferral that can freeze the clock, and selling before the tax sale to protect the equity you’d otherwise lose at auction. We’ll lay out what each path costs and what you keep, so you can pick the one that fits your situation.
We are not attorneys, CPAs, or tax advisors, and this is not legal or tax advice. The numbers and statutes below track the Texas Property Tax Code as of 2026, but penalty schedules, attorney-fee percentages, and timelines vary by taxing unit and county, and your specific situation may differ. Before you make a decision with this much money on the line, talk to your county tax office and a licensed Texas property-tax attorney or CPA. What we can give you is the operator-side view from buying Texas houses with delinquent taxes and watching the math play out.
What happens when you don’t pay Texas property taxes — the delinquency timeline
Texas property taxes run on a calendar that’s worth understanding, because every date on it costs you money.
- January 1 — A tax lien automatically attaches to your property for that year’s taxes, before you’ve even gotten the bill. This is why delinquent taxes follow the house and have to be cleared at any sale.
- October–December — Tax bills go out. Taxes are due upon receipt and payable through January 31 without penalty.
- February 1 — Unpaid taxes become delinquent. Penalty and interest start immediately (see the math below).
- Spring/summer — The taxing units send dunning notices. Around July 1, most units turn the account over to a collection law firm, which adds an additional penalty for attorney fees.
- The lawsuit — If the balance stays unpaid, the taxing unit’s attorney files suit in district court to foreclose the tax lien. You’re served, and you have a chance to respond.
- Judgment and sheriff’s sale — Once the court grants judgment, the property is posted and sold at a public tax sale on the first Tuesday of the month, the same courthouse-steps auction used for mortgage foreclosures.
The key thing to understand: unlike a mortgage foreclosure, a Texas property-tax foreclosure is judicial — the county has to sue you and win in court first. That makes it slower, but it does not make it optional. And the slower it goes, the more penalty, interest, and attorney fees pile onto the balance you’ll eventually have to clear.
The penalty math — how the balance snowballs
This is the part that catches people off guard. Texas property-tax penalties are front-loaded and they compound monthly. Under Texas Tax Code §33.01, a delinquent tax incurs a 6% penalty the first month plus 1% interest, then the penalty rises 1% per month while interest also rises 1% per month — until July 1, when the penalty caps at 12% (interest keeps climbing 1% per month after that).
Here’s the standard schedule for a tax that goes delinquent February 1, 2026. The “collection fee” column reflects the additional penalty most taxing units add around July 1 under §33.07/§33.08 to cover collection-attorney costs. By statute that penalty can’t exceed the fee the unit agreed to pay its attorney — in practice it’s commonly set up to 20% of the taxes, penalties, and interest due, depending on your jurisdiction.
| Month (2026) | Penalty | Interest | Subtotal | + Collection fee (up to ~20%) | Total |
|---|---|---|---|---|---|
| February | 6% | 1% | 7% | — | 7% |
| March | 7% | 2% | 9% | — | 9% |
| April | 8% | 3% | 11% | — | 11% |
| May | 9% | 4% | 13% | — | 13% |
| June | 10% | 5% | 15% | — | 15% |
| July 1 | 12% | 6% | 18% | + up to ~20% | up to ~41.6% |
| Each month after | 12% (capped) | +1%/mo | — | (already added) | grows ~1%/mo |
Run a real number on it. Say you owe $6,000 in property taxes for the year. Pay in February and you add about $420 (7%) in penalty and interest — roughly $6,420. Let it ride to July, and the 18% penalty-and-interest plus a collection fee of up to ~20% push the balance toward roughly $8,500 — about $2,500 more than the tax itself. Wait longer and interest keeps grinding higher at ~1% a month. The math is brutal precisely because it’s designed to get your attention early.
How long before the county can actually sell?
Because Texas requires a lawsuit and a court judgment before a tax sale, the timeline is measured in months, not days — but the exact length depends on the county’s docket and whether you respond to the suit. From the law firm filing the petition to the sheriff’s sale is commonly several months to well over a year. Once judgment is entered, the property is posted and sold the first Tuesday of an upcoming month.
Two more things to know. First, the redemption period. If your home was your residence homestead and it does sell at a tax sale, Texas gives you two years to redeem it — but you have to pay the buyer back everything they paid plus a redemption premium of 25% in the first year, or 50% in the second year (under Tax Code §34.21). That’s an expensive way to recover a house, and it’s why protecting the equity before the sale beats trying to claw it back after. Second, this guide covers the tax-foreclosure clock specifically. If you also have a mortgage in default, that’s a separate and faster track — see the full Texas foreclosure timeline for how mortgage foreclosure moves, and use the foreclosure countdown tool to gauge how much time is realistically left.
First, figure out where you stand
Before you pick an option, get three facts straight:
- How much do you actually owe, all-in? Call your county tax office (or pull a tax certificate) for the exact balance including current penalty, interest, and any attorney fees. The headline tax number is rarely the real number.
- Has a lawsuit been filed yet? If you’ve been served, you’re further down the timeline and your window is shorter. If not, you likely have more room to negotiate a plan.
- Do you have equity? Roughly: what could the home sell for, minus the mortgage payoff, minus the delinquent taxes. If there’s real equity, a sale protects it. If you’re upside-down, the calculus changes.
With those three numbers, the options below stop being abstract.
Option 1 — Pay it off or set up an installment agreement with the county
If the hardship is temporary and you can catch up, paying the balance (taxes + penalty + interest + any fees) ends it cleanly and releases the lien.
If you can’t pay it all at once, ask about an installment agreement under Texas Tax Code §33.02. A tax collector may enter an installment plan on delinquent taxes for any owner — and for a residence homestead with a §11.13 homestead exemption, the collector must offer a payment plan (at least 12 months, up to 36) if you haven’t had an agreement with that taxing unit in the prior 24 months. Read the agreement carefully: on a homestead plan the §33.01(a) penalty stops accruing while the agreement is in force, but interest generally keeps adding up, and missing a payment can void the plan and restart collection.
Cost: the taxes plus accrued interest (and penalty/attorney fees if you’re past July 1 or not on a homestead plan). Time: spreads over months/years. What you keep: the house. Best for: a temporary cash crunch where you can realistically make the monthly payments.
Option 2 — Texas deferrals and exemptions (over-65, disabled, homestead)
This is the most overlooked lifeline in the code. Under §33.06, a homeowner who is 65 or older, disabled, or a qualifying disabled veteran can file a tax-deferral affidavit on their residence homestead. Filing it stops a pending tax suit or tax sale and pauses collection for as long as you own and live in the home. Taxes keep accruing during the deferral, but at a reduced 5% annual interest instead of the punishing standard schedule, and the full balance only comes due when you sell, move out, or pass away — at which point your heirs get a window to pay it. The lien stays on the home, so this defers the bill rather than erasing it.
Separately, homeowners who are 65+ or disabled can pay current-year homestead taxes in four installments without penalty and interest under §31.031, and your homestead exemption itself lowers the taxable value going forward. If an elderly parent or relative is behind on taxes, the deferral affidavit alone can buy years of breathing room.
Cost: 5% annual interest while deferred (much cheaper than the standard penalty schedule). Time: indefinite, while you own and occupy. What you keep: the house, and you stay in it. Best for: qualifying seniors and disabled owners who want to keep the home.
Option 3 — Sell before the tax sale to protect your equity
If the hardship isn’t temporary, you don’t qualify for a deferral, or the lawsuit is already moving and the math no longer works — selling the house before the county does is often the move that actually protects you. Here’s why: a tax sale can erase the equity above what’s owed. The auction’s job is to satisfy the tax debt, not to maximize what you walk away with. A normal sale, by contrast, pays the taxes off the top and hands you whatever’s left.
There are two ways to sell:
- Traditional listing — usually nets the most if you have 60–90+ days, the house shows well, and you can handle repairs and showings. The delinquent taxes get cleared at closing out of the proceeds.
- Cash, as-is sale — closes in roughly one to two weeks, no repairs, no commission, no financing contingency to fall through. Best when the sale date is closer than a normal closing or the house needs work you can’t fund.
Either way, the title company clears the taxes at closing. It runs a tax certificate, pays the delinquent taxes plus all penalty, interest, and attorney fees directly to the taxing units, and the statutory lien is released so the buyer takes clear title. You never write the county a separate check — it comes off the top. For a line-by-line look at how the two selling paths compare on net proceeds, see cash offer vs. listing — the real math.
What each option actually costs — side by side
| Option | Out of pocket | Time to resolve | What you keep | Best when |
|---|---|---|---|---|
| Pay in full | Taxes + P&I (+ fees if past July 1) | Immediate | The house | You can catch up now |
| Installment plan (§33.02) | Taxes + interest, spread out (penalty paused on homestead plan) | 12–36 months | The house | Temporary cash crunch, can make payments |
| Deferral (§33.06) | 5%/yr interest, deferred | Indefinite while you live there | The house + you stay | You’re 65+, disabled, or disabled vet |
| Sell — traditional listing | Commission + repairs (taxes paid at closing) | 60–90+ days | Equity after taxes/payoff | House shows well, you have time |
| Sell — as-is cash | $0 repairs, no commission (taxes paid at closing) | ~1–2 weeks | Equity after taxes/payoff | Clock is short, house needs work |
| Do nothing → tax sale | Loses control of price; redemption costs +25–50% | Months to 1+ year | Often little to nothing | Never the goal |
Pay, defer, or sell? A simple decision framework
Pay off or set up a plan when the hardship is temporary, you qualify for or can negotiate an installment agreement, and you can realistically make the payments without falling behind again.
File a deferral when you (or the homeowner you’re helping) are 65+, disabled, or a disabled veteran, the home is the residence homestead, and the goal is to stay in the house. This freezes the clock at 5% interest — almost always the right move if you qualify and want to keep the home.
Sell when any of these are true:
- The hardship isn’t temporary and a plan would just keep you behind.
- You don’t qualify for a deferral and can’t fund the catch-up.
- There’s real equity a tax sale would erase — selling protects it.
- The tax suit is already filed and the timeline is closing in.
- The taxes are stacked on top of other problems (deferred repairs, a mortgage default, an inherited house you can’t carry).
And within “sell,” list it if the house shows well and you have 60+ days; sell as-is for cash if the clock is shorter than a normal closing or the home needs work you can’t or won’t fund.
How selling as-is clears the taxes — and protects what’s left
If you’ve read this far and the honest answer is “I’m out of runway” — the penalties are climbing faster than you can catch up and the tax-sale clock is running — then selling before the county does is often the cleanest exit. A sale pays off the taxes and any mortgage, stops the foreclosure before it hits the public record and erases your equity at auction, and lets you walk away with whatever equity is left instead of losing it on the courthouse steps.
A traditional listing usually nets the most if you have the time and the house shows well. But if the home needs repairs you can’t fund, or the first-Tuesday sale is closer than a normal closing, selling as-is to a cash buyer can close in as little as one to two weeks — no repairs, no agent commission, no financing contingency, and the delinquent taxes and lien paid directly to the county at the title company. A fair as-is cash offer is built off the home’s after-repair value at roughly 75–80%, minus the cost of the repairs the house needs — so the more work it needs, the further the offer sits below full retail. That’s the honest tradeoff you’re accepting in exchange for speed and certainty. It won’t beat a clean retail sale on price, but when the clock is the enemy, a definite closing date can be worth more than a higher number you can’t reach in time.
The bottom line
Falling behind on Texas property taxes is a math problem with a deadline, not a moral failing — and you have more options than the penalty notices suggest. Catch up or get on a plan if the hardship is temporary. File the §33.06 deferral if you qualify; it’s the most powerful tool in the code for keeping the home. And if neither fits, sell before the tax sale erases the equity you’ve built.
Knowing your options is free. If you want to see what an as-is cash offer would actually look like for your situation — including exactly what the taxes take and what you’d walk away with — you can tell us about the property and we’ll run honest numbers. If listing it the traditional way, getting on a county payment plan, or filing a deferral is genuinely the better move for you, we’ll tell you that too. No pressure, no fees, and no obligation.
