Your property tax notice has arrived. Here is the exact penalty calendar, the county’s own payment plan, why the tax lender mailers flooding your mailbox may cost you far more than the original debt, and when Harris County actually moves to foreclose.
If you opened a Harris County property tax notice and felt your stomach drop, you’re not alone. You have until January 31, 2025 to pay. After that, the penalties start and compound in ways the county’s website does not explain clearly — and I mean that literally. I spent time on harriscountytax.com before writing this and could not find a plain-English breakdown of the delinquency schedule anywhere on the front-facing pages.
This piece covers what you actually owe at each stage of delinquency, the installment plan the county offers but doesn’t prominently advertise, a split-payment option most homeowners have never heard of, the deferral program for older and disabled homeowners, and a straight account of the property tax lending industry flooding Houston mailboxes with offers. These are not equivalent options. The differences matter.
Two Dates That Control Everything
The January 31 deadline is firm. Texas law provides no grace period. February 1 is day one of delinquency, and penalties begin immediately. There is no “a few days late” in Harris County tax law. None.
The second date is July 1, and it matters more than most delinquent taxpayers realize. On July 1 of each year, any account still carrying a balance from the prior year’s taxes goes to outside counsel. Harris County holds a contract with private law firms for this work. At that moment, a 20% attorney collection penalty attaches to the outstanding tax, penalty, and interest balance — by statute, not by negotiation. That fee doesn’t disappear if you subsequently pay. It doesn’t shrink if you work out an arrangement. It’s locked in on July 1 and owed, full stop.
Between February 1 and June 30, you’re accumulating penalties and interest. The situation is manageable without that additional 20% layer. After July 1, you cannot avoid it.
The Exact Penalty Calendar
Under Texas Tax Code Chapter 33, delinquency penalties and interest accrue on a fixed schedule. Here’s what that looks like in real numbers, using a $10,000 tax bill as a baseline.
On February 1, a 6% penalty plus 1% interest attaches immediately. You owe $10,700. Each month through June, another 1% penalty adds on: $10,800 in March, $10,900 in April, $11,000 in May, $11,100 in June. Then July 1 hits. The 20% attorney collection penalty attaches to the existing balance and you’re suddenly looking at roughly $13,200 on that original $10,000 bill — about 32% overhead total.
After July 1, interest keeps running at 1% per month on the full balance. By the following January, roughly 18 months after the original deadline, total overhead can exceed 47%. A $10,000 bill has grown by nearly half. That’s not a hypothetical pulled from thin air. That’s what the statute requires.
If a second tax year goes unpaid, a fresh round of delinquency penalties begins on that balance too. Accounts at that stage are almost certainly in active litigation or very close to it.
One clarification worth making: the monthly figures through June combine an escalating penalty structure with a separate 1% monthly interest charge that never stops running. The July 1 attorney collection fee is statutory — it comes from Harris County law, not from administrative discretion.
Harris County’s delinquent tax collection is handled by outside law firms. The dominant contractor is Linebarger Goggan Blair & Sampson, LLP, one of the largest municipal debt collectors in the country, headquartered in Austin. Their fee attaches automatically on July 1 regardless of whether suit has been filed. These are not debt collectors in the consumer-credit sense. They’re attorneys authorized to file suit in Harris County District Court — a distinction worth understanding before you decide how urgently to act. You can confirm the current contractor at harriscountytax.com or by calling 713-274-8000.
The County’s Own Payment Plan and What It Actually Costs
Before you call a number from a mailer or sign anything, know that Harris County offers its own installment agreement for delinquent taxes under Texas Tax Code Sec. 33.02. It’s not prominently displayed on harriscountytax.com. There’s no banner, no tab labeled “payment plan.” You have to ask for it by name.
The phrase to use, whether you call or walk in: “delinquent tax installment agreement.”
To apply, contact the Harris County Tax Assessor-Collector:
- Main office: 1001 Preston St., Houston, TX 77002
- Phone: 713-274-8000
- Website: harriscountytax.com
- Satellite offices in Baytown, Humble, Katy, and Pasadena. Call ahead to confirm services and hours at each location before making the drive.
When you enter the plan, the Tax Assessor structures a monthly payment schedule based on your circumstances. The 1% monthly interest rate continues accruing on the outstanding balance throughout. If the July 1 attorney fee has already attached, it stays in your balance — nothing is forgiven. What the plan actually buys you is time and a predictable payment path. It stops the situation from deteriorating further while you work through it.
The sooner you contact the office, the more flexibility you’ll have. Homeowners who wait until March tend to find fewer options available than those who call in January. If you already know January 31 will be a problem, call now, before penalties even begin. For a broader look at property tax exemptions that may reduce your underlying bill, our property tax exemptions Houston homeowners guide covers overlapping relief programs that can lower the amount you owe before delinquency ever starts.
The Split Payment Option Most Houston Homeowners Don’t Know Exists
If you’re reading this before November 30 and your taxes are still current, there’s a tool that almost nobody uses because almost nobody knows about it. I’m a little baffled it isn’t advertised more prominently.
Texas Tax Code Sec. 31.03 allows qualifying homeowners to split their annual tax payment into two installments with no penalty. Pay at least half the total bill by November 30, and pay the remainder by June 30 of the following year. For a homeowner staring at a $12,000 annual bill who knows the full amount isn’t realistic by January 31, this changes the calculation entirely. Pay $6,000 by November 30 and the remaining $6,000 by June 30. No penalties. No interest. No attorney fees.
Confirm with the Harris County Tax Assessor-Collector at harriscountytax.com or 713-274-8000 that this option is currently available for the 2024 tax year before relying on it. The November 30 cutoff is absolute. Miss it, and the option is gone for this tax year. But if you can come up with half your bill in the next several weeks, you buy yourself six additional months on the rest at zero penalty cost. That’s a genuinely good deal.
If You Are 65 or Older or Have a Disability
The deferral program under Texas Tax Code Sec. 33.06 works differently from everything else in this article, and it’s administered by a different county agency than the Tax Assessor. That distinction trips people up constantly.
The deferral affidavit is filed with the Harris County Appraisal District (HCAD), not the Tax Assessor-Collector. The address is 13013 Northwest Freeway, Houston, TX 77040. The phone number is 713-957-7800. Many homeowners lose time by calling the Tax Assessor first — an easy mistake when you’re stressed and trying to solve something quickly.
Once the affidavit is filed and approved, collection of delinquent taxes on the homestead is deferred. The county cannot initiate foreclosure while the deferral is active and the homeowner remains in the property. The interest rate on a deferred account drops to 5% per year — significantly lower than the standard 1% monthly statutory rate.
Eligibility requires being 65 or older, or qualifying as disabled, and holding a qualifying homestead exemption. Confirm disability qualification requirements and necessary documentation directly with HCAD at 713-957-7800 before applying. Eligibility standards are specific.
Now, the part that’s rarely explained: the deferral does not forgive taxes. It defers them with interest accumulating against the property. A homeowner who defers taxes year after year builds a lien that grows every year and attaches to the estate. Heirs who want to keep the property will need to pay the full deferred amount plus interest. They get 180 days after the homeowner’s death before collection resumes.
For an older homeowner on a fixed income who intends to age in place and whose heirs understand the trade-off, the deferral may be the best option available. It converts an impossible current obligation into a manageable future one at a lower interest rate than any commercial lender will offer. That’s real. But the heirs need to know what’s coming.
Separately, homeowners 65 and older with a homestead exemption are entitled to a school district tax freeze. The school portion of the tax bill cannot increase above the amount assessed in the year the freeze was established. This is an exemption benefit, not a deferral, and it should already be in place if you applied for the over-65 exemption. If you’re 65 or older and your school taxes have been rising, check your exemption status with HCAD directly at 713-957-7800.
The Tax Lender Mailers — What They’re Not Telling You
Shortly after Harris County tax bills arrive — and certainly after February 1 — Houston homeowners start receiving mailers from property tax lenders. The pitch: “We’ll pay your taxes immediately and you pay us back monthly.” In narrow circumstances it may solve the immediate problem. But the terms deserve closer reading than the mailer is designed to encourage.
Property tax lenders pay your bill directly to the county, then place a senior contractual lien on your property. In many cases, that lien is senior to your mortgage. They’re not helping you avoid a lien. They’re replacing the county’s statutory tax lien with their own contractual lien under Texas law. The county gets paid. Now you owe the lender.
The county’s statutory interest rate on delinquent taxes is 1% per month, or 12% annually. Property tax lenders in the Houston market typically charge significantly more — often 18% to 36% APR depending on the lender and the borrower’s profile — plus origination fees and closing costs that can add meaningfully to the total obligation. Some of the most actively advertised lenders in the Houston market include Propel Tax and Tax Ease. To verify whether a lender is legally registered to operate in Texas, use the Texas Office of Consumer Credit Commissioner’s lender lookup tool at finance.texas.gov. Don’t sign anything with any lender whose OCCC registration you haven’t confirmed.
The scenario I’d want every Houston homeowner to understand before signing: a property tax lender’s lien may trigger an acceleration clause in your mortgage. Many standard mortgage agreements contain language treating an additional senior lien on the property as a default event, or requiring the borrower’s consent before one is placed. If your servicer treats the tax lender’s lien as a breach, you could face a mortgage default demand on top of the original tax problem. Before signing anything with a property tax lender, pull out your mortgage documents and look for that language — or call your servicer directly and ask.
Property tax lenders also foreclose faster than Harris County typically does. The county, managing a large delinquent portfolio, often doesn’t initiate suit for two to three years. A property tax lender with a contractual lien and a private financial interest will move sooner. The foreclosure process for a tax lender lien is still judicial in Texas — it requires court action — but a motivated private lienholder reaches the courthouse faster than a county managing thousands of delinquent accounts.
For some homeowners facing the July 1 attorney fee cliff, a lender’s rate may genuinely be lower than the combined county penalties, or the county’s installment terms may not work for their cash flow. There may be a case for it. The point is to make that comparison with accurate numbers, not with the simplified math in the mailer. In our legal & finance coverage, we’ve looked at other situations — from tenant rights to wage claims — where the advertised “easy” option frequently carries hidden costs worth modeling out first.
When Does Harris County Actually Foreclose
Not quickly. But the debt compounds the entire time — and that’s what the slower timeline can obscure.
Under Texas Tax Code Sec. 33.41, Harris County may file suit beginning February 1 of the year following the delinquency. For taxes unpaid from the 2024 tax year, that means suit could theoretically be filed as early as February 1, 2026. In practice, given the volume of delinquent accounts in the third-largest county in the country by population, the county typically doesn’t file suit until two to three years of delinquency have accumulated. Many homeowners facing a 2024 default won’t see active litigation until 2027 or 2028.
Tax foreclosure in Texas is judicial, not the faster non-judicial process used for mortgage default. The county must file suit, obtain a court judgment, and schedule a constable’s sale — a process that takes months even without contested litigation. Foreclosure sales for delinquent taxes are posted on the Harris County District Clerk’s website at hcdistrictclerk.com.
The slower county timeline doesn’t mean the debt is sitting still. It keeps accruing 1% monthly interest on the full outstanding balance, plus any additional years’ taxes that have also gone unpaid, plus attorney fees from subsequent July 1 attachment dates. By the time suit is filed two years later, the obligation has grown substantially. And if a property tax lender has placed a lien, that lender is operating on its own timeline — not the county’s. For context on how the Harris County eviction process operates through the same court system, the parallels in timeline and judicial requirements are instructive.
What to Do This Week
The most common practical mistake Harris County homeowners make is confusing two offices that handle two different things. It costs people time they don’t have.
The Harris County Appraisal District handles exemptions and deferrals: the over-65 freeze, the disability deferral affidavit, homestead exemption applications. HCAD does not collect taxes and cannot set up a payment plan.
- Address: 13013 Northwest Freeway, Houston, TX 77040
- Phone: 713-957-7800
- Website: hcad.org
The Harris County Tax Assessor-Collector handles your bill, payment, and installment agreements.
- Main office: 1001 Preston St., Houston, TX 77002
- Phone: 713-274-8000
- Website: harriscountytax.com
- Satellite offices in Baytown, Humble, Katy, and Pasadena. Call ahead to confirm services and hours before visiting.
In January and February, wait times at 1001 Preston are long. If you’re acting now, you have an advantage over the homeowners who will be standing in that line in six weeks. Use it. When you call or walk in to the Tax Assessor’s office, say: “I want to apply for a delinquent tax installment agreement under Section 33.02.” That tells the staff exactly what you need.
Before you sign anything with a property tax lender, verify their OCCC registration at finance.texas.gov. Call your mortgage servicer and ask specifically whether a tax lender lien would constitute a default event under your loan documents. Then compare the lender’s total cost — APR plus origination fees and closing costs — against the county’s statutory penalty and interest schedule for your actual timeline.
If you’re 65 or older or disabled and haven’t filed a deferral affidavit, contact HCAD at 713-957-7800 before your account goes delinquent. The deferral takes time to process, and the sooner it’s filed, the sooner the 5% annual interest rate applies instead of the standard statutory rate.
If you’re current on your taxes and know January 31 will be difficult, ask the Tax Assessor-Collector whether the split payment option is available for your property this tax year. If it is, the November 30 first-installment deadline may be weeks away. Half your bill by November 30, the rest by June 30, no penalty. That window doesn’t reopen once it closes.
The options here are not equally good, and none of them are free. The penalty calendar above is not hypothetical. It’s what Harris County statutes require, and it runs whether or not you open the envelope.
