If you own a home in Houston or Harris County, you’ve probably noticed that nobody agrees on what the property tax rate actually is. Ask a Midtown neighbor, a Katy friend, and a coworker in Pearland. Three different answers, all technically correct for their address. This isn’t confusion — it’s how Texas built the system, stacking multiple taxing entities on top of each other, varying sharply by whether you live inside city limits, in a suburb with a Municipal Utility District, or across a county line. This guide walks through the full pipeline: how the Harris County Appraisal District values your home, what lands in your mailbox in November, real dollar figures, current rates, and the details first-year owners miss until it costs them money.
Two Houses, Same Price, Very Different Bills
The spread is larger than most people expect.
Take a $350,000 home in Midtown Houston (ZIP 77002) and a $350,000 home in Katy’s Cinco Ranch area (ZIP 77494, Harris County side). Same purchase price, same county. The bills are nowhere close.
Midtown Houston (77002) — inside City of Houston limits, HISD
After the standard homestead exemption, the taxable value on a $350,000 home drops by $100,000 for the school district portion (per the 2023 legislative increase) and by $20,000 for county purposes. Rates below are drawn from published figures; verify against each entity’s 2024 adopted rate documents at hcad.org and harriscountytx.gov before using them for any financial calculation.
| Taxing Entity | Rate per $100 (approx.) | Notes |
|---|---|---|
| Houston ISD (on $250,000 taxable) | ~$0.8520 | Post-TEA takeover and 2023 compression; confirm 2024 adopted rate |
| Harris County General Fund | ~$0.3764 | Verify 2024 adopted rate from harriscountytx.gov |
| Harris County Flood Control | ~$0.0328 | Post-Harvey bond program |
| Port of Houston Authority | ~$0.0045 | Appears on every Harris County bill |
| Harris Health System | ~$0.1659 | Ben Taub, LBJ Hospital, county indigent care |
| Harris County Dept. of Education | ~$0.0052 | Intermediate service agency; not HISD |
| City of Houston | ~$0.5336 | Inside Houston city limits only |
(Taxable value for county lines: $330,000 after $20,000 homestead exemption. School district line: $250,000 after $100,000 exemption. All rates require confirmation from each entity’s 2024 Truth-in-Taxation certified documents. Blended effective rate for a home in Houston proper runs roughly 2.0–2.2% of appraised value.)
Katy/Cinco Ranch (77494) — unincorporated Harris County, Katy ISD, with a MUD
Same $350,000 home, outside Houston city limits. No City of Houston tax. Instead, a Municipal Utility District rate appears, and Katy ISD’s rate differs from HISD’s. Both must be confirmed from each entity’s Truth-in-Taxation notice. Katy-area new construction MUD rates alone frequently run $1.00 to $1.50 per $100 on top of county and ISD rates.
The assumption that you pay more taxes inside Houston often reverses once MUD debt service enters the picture. On an identical $350,000 home in Cinco Ranch, the MUD line alone can add $1,200 to $1,750 annually compared to the City of Houston line in Midtown. This is why the tax complaints you hear in the suburbs sound different than the ones inside the Loop. The levies actually are structured differently, and the numbers back it up.
Who Is Actually Taxing You
Every Harris County tax bill contains separate levies from separate governmental entities. Knowing which line is which tells you something useful: which ones you can influence, which you can’t, and which appear on every bill regardless of your address.
Harris County General Fund pays for the county’s basic operations — courts, the sheriff’s department, county roads and infrastructure. Current rate: approximately $0.3764 per $100; confirm the 2024 adopted rate at harriscountytx.gov. This line is on every bill in the county, no exceptions.
Harris County Flood Control District funds regional detention basins, bayou projects, and the ongoing bond work accelerated after Harvey. Rate: approximately $0.0328 per $100. Small on a per-home basis, but it supports billions in infrastructure spread across the entire watershed. If you were here during Harvey, you may have complicated feelings about whether the spending is sufficient. That’s a legitimate debate. Either way, every Harris County homeowner carries a share.
Port of Houston Authority is one of the country’s largest ports by tonnage, funded partly through property tax. The levy is modest — approximately $0.0045 per $100 — but it appears on every Harris County bill regardless of how far you live from the Ship Channel. A Cypress homeowner paying to maintain a port facility 30 miles away might reasonably ask why. The answer is that Harris County taxes have historically funded regional infrastructure this way. You won’t win that argument, but at least you know where the line comes from.
Harris Health System operates Ben Taub, LBJ Hospital, and the county’s indigent care network. Rate: approximately $0.1659 per $100. The system carries the region’s safety-net responsibilities, and the tax base is what funds it.
Harris County Department of Education is not HISD. It’s not any independent school district. This trips up nearly every first-year owner who looks at the bill closely. It’s an intermediate service agency providing shared services to school districts across multiple counties — teacher training, special education consulting, that kind of operation. Its levy is minimal, approximately $0.0052 per $100, but it appears on every bill and genuinely looks like a duplicate school district charge if you don’t already know what it is.
City of Houston applies only if your property sits inside Houston city limits. At approximately $0.5336 per $100, it’s the second-largest line on the bill for anyone in 77002 or other central Houston addresses. Properties in unincorporated Harris County — most of Katy, Cypress, Humble — pay nothing on this line. Cross into city limits, you pay it. Stay outside, you don’t. It’s the most dramatic on-off switch in the entire bill structure.
Your ISD is usually the single largest line on the bill. HISD’s approximate 2024 rate is $0.8520 per $100, but this is also the most volatile element and requires direct confirmation from HISD’s adopted budget documents. Following the Texas Education Agency state takeover in 2023 and House Bill 3’s compression requirements, HISD’s rate has declined from prior years. The compression formula ties district M&O rates to state funding recapture, meaning the rate can keep moving — sometimes down, sometimes back up — based on state funding decisions largely outside HISD’s control. If you own in HISD, treat that line as a variable, not a fixed cost.
The MUD Factor
Municipal Utility Districts are the most underreported element in Houston-area property tax coverage. They’re also the main reason a suburban home at the same price point can carry a meaningfully higher tax burden than one inside the Loop.
Here’s the basic mechanic: when a developer builds a master-planned community in unincorporated Texas, the county doesn’t extend water, sewer, and drainage infrastructure to the site. Instead, the developer forms a MUD under state law, the MUD issues bonds to finance the utility infrastructure, and the homebuyers who move in become the district’s tax base. They repay the bonds through their annual MUD levy — for decades, in many cases. The developer is long gone. The debt stays with the neighborhood. That’s the honest description of how it works.
MUD rates vary enormously depending on how much infrastructure was financed, how aggressively it was bonded, and how much the tax base has grown since. A well-established MUD in older Katy or Pearland may have largely retired its debt. A newer MUD in Bridgeland or the outer Cypress corridor may still be at peak debt service and will likely stay there for another decade or more.
Some figures from recent Truth-in-Taxation notices:
Cypress-area MUDs (northwest Harris County): Districts like Harris County MUD 249 and MUD 358 carry MUD-only rates in the range of $0.90 to $1.20 per $100. A homeowner at the high end of that range, stacked on top of Harris County rates, an ISD rate, and a flood control district, can reach a combined effective rate approaching or exceeding 2.5 percent. That’s higher than Midtown Houston.
Katy/Cinco Ranch MUDs (west Harris County): New construction buyers in this corridor regularly encounter MUD rates of $1.00 to $1.50 per $100. This is the top tax complaint in buyer discussions for the corridor, and it’s a legitimate one. A buyer expecting a $7,000 annual bill finds out it’s actually $8,500 or $9,000 once the MUD is included — after closing, once the first November rolls around.
Bridgeland (Cypress): A newer master-planned community still in build-out. Associated MUD rates are likely to stay elevated for another decade or more. Pull the specific district rate from the Comptroller’s transparency site before purchasing here.
Sienna/Missouri City (Fort Bend County): Fort Bend County’s rate structure differs from Harris County — generally lower county-level rates — but Sienna MUDs have historically run $0.40 to $0.65 per $100. The lower county base actually helps here, even accounting for the MUD.
Pearland: Split between Harris and Brazoria counties. Neighborhoods that feel like one continuous community are sometimes in different counties with different rate structures. Brazoria County’s base rates run lower than Harris County’s. Always confirm your county before comparing bills with a neighbor across the subdivision line.
Sugar Land sits almost entirely in Fort Bend County. The Woodlands is in Montgomery County — a separate rate stack entirely, with different county, flood control, and ISD lines. Rate comparisons across county lines are nearly meaningless unless you’re working from actual certified rolls for each specific address.
To look up your specific district: go to the Texas Comptroller’s Property Tax Transparency Website at comptroller.texas.gov/taxes/property-tax/. Enter your address and you’ll see every taxing unit that applies, with current adopted rates. This is the authoritative source. Not a Zillow estimate, not a lender’s pre-closing guess. If you’re choosing between two neighborhoods in different MUD districts, this is where you settle the question.
How HCAD Arrives at Your Appraised Value
HCAD values approximately 1.8 million property accounts annually. It does not send an appraiser to inspect your home. It uses mass appraisal — a statistical modeling process applying cost, income, and sales-comparison methods across large groups of similar properties. Your home gets a value based on how comparable sales and property characteristics cluster in your neighborhood.
The legally controlling date is January 1. HCAD values your property based on market conditions and physical condition as of that date. If your roof was damaged in a storm on January 2, it doesn’t affect that year’s appraisal — it may matter the following year. If you purchased on January 2, the prior owner’s exemption status controlled that year’s bill. Your exemptions begin the year after. This timing distinction is why first-year owners often get a surprise bill in year two, and it’s the kind of thing nobody mentions at closing.
HCAD draws comparable sales data primarily from deed transfer records filed with the county clerk, not MLS data. That distinction matters when you protest. HCAD’s automated model may not have complete access to listing-level data showing condition, seller concessions, or unusual circumstances affecting a sale price. That gap can work in your favor, especially when you have specific knowledge of comparable sales the model missed or misclassified.
The 10 percent cap limits how much HCAD can increase the appraised value of a homesteaded property in a single year, regardless of market movement. If HCAD’s model calculates your home at $420,000 but it was appraised at $350,000 last year, the cap holds your taxable appraised value at $385,000. Three things routinely catch owners off guard here. First, the cap applies only to properties with a qualifying homestead exemption — investment properties, rentals, and vacant land get nothing. Second, the cap covers only the improvement, not the land. A large land reassessment can partially offset the benefit if land values have jumped sharply. Third, and this surprises buyers more than the other two combined: the cap resets to full market value when the property sells. If you paid $500,000 for a home the prior owner had capped at $380,000, your first HCAD notice will show a number much closer to your purchase price. That reset is the main reason escrow accounts run short in year two for new buyers who assumed continuity with the previous owner’s bill.
Exemptions That Lower Your Bill and How to Apply
The homestead exemption is the foundational reduction, and it doesn’t happen automatically. You must apply.
You must own the property and occupy it as your primary residence as of January 1 of the tax year. The application deadline is April 30. Your Texas driver’s license or state ID must show the property address at the time of application. This is the most common reason HCAD rejects applications — the ID still shows an old address. Update your license first.
Apply at hcad.org or mail a paper form to HCAD at 13013 Northwest Freeway, Houston TX 77040. HCAD charges no fee. Services charging you to file a homestead exemption are marking up a free government process, and they exist specifically because buyers don’t know it’s free.
Once approved, the homestead exemption provides a $20,000 reduction in taxable value for county purposes and a $100,000 reduction for the school district M&O calculation — the latter increased from $40,000 under the 2023 Texas legislative session. On a $350,000 home, that difference is roughly $850 annually in school taxes alone. For a fuller picture of the exemptions Houston homeowners frequently overlook beyond the standard homestead, our property tax exemptions guide for Houston homeowners covers the senior freeze, disability exemptions, and partial exemptions that many owners never claim.
The over-65 exemption and tax ceiling is the most misunderstood benefit in Texas property tax law, and also the most valuable one available to any Houston homeowner. Once you qualify — you must be 65 by January 1 of the tax year and have a homestead exemption in place — the school district portion of your bill stops increasing. HISD or whatever ISD applies cannot collect more than it collected in the year you first qualified, regardless of rising appraisals or rising rates. A homeowner who first qualifies when their school tax bill is $3,200 will pay $3,200 in school taxes that year and every year afterward, even if their home appreciates to $600,000.
What the freeze doesn’t cover: the county portion, city taxes, Flood Control and Port Authority levies, and any MUD rate. Those can still rise. The ceiling also transfers proportionally if you sell and buy a new homestead — it applies proportionally to the new home’s value rather than carrying over in full. A surviving spouse who is at least 55 may maintain the freeze. Apply at hcad.org alongside the standard homestead form.
The 100 percent disabled veteran exemption eliminates all property taxes on the homestead for veterans rated at 100 percent disabled by the VA. A full exemption, not a reduction — it applies to all taxing entities including any MUD levy. Surviving spouses of qualifying veterans may also be eligible. If you know a veteran who might qualify and hasn’t applied, that’s a conversation worth having.
One more thing first-year owners need to know: the exemption does not apply retroactively. If you bought your home in July, you get no homestead exemption for that tax year. The prior owner’s exemption status controlled. You’ll apply for the exemption that takes effect January 1 of the following year. Many first-year buyers discover this in February when the bill arrives, the escrow account is short, and the servicer charges them for the overage. Plan ahead.
How to Protest Your Appraisal and What Evidence Actually Works
HCAD mails appraisal notices in April. The protest deadline is May 15, or 30 days from the postmark on your notice, whichever is later. If you miss it, your only remaining option is district court — far more expensive and slow than the appraisal review process you bypassed.
The process runs in two stages. First, an informal hearing with an HCAD staff appraiser, usually by phone or through the online portal. Most protests that succeed resolve here. Second, if the informal hearing doesn’t work, you can take your case to the Appraisal Review Board, an independent panel that hears formal evidence and issues a binding determination. You can bypass the informal stage and go straight to the ARB, but most people start with the informal hearing because it’s faster and requires less documentation.
File through the iFile portal at hcad.org.
Two distinct protest arguments exist. Using the wrong one wastes your time.
The market value argument says your home is worth less than HCAD says. You support it with comparable sales — homes similar to yours that sold for less than your appraised value in the months before January 1. The limitation: HCAD may have sales data you don’t, or may dispute your comps’ comparability. You can argue your home is smaller, older, or in worse condition than HCAD’s selections, but you’re working against an agency with a larger dataset. If you have comps showing lower values in your immediate neighborhood, the argument is worth making. If you don’t, it isn’t.
The unequal appraisal argument is different, and often more effective. It says your home is appraised at a higher percentage of market value than comparable properties in HCAD’s own records — not compared to outside sales, but to HCAD’s own numbers. Texas law requires appraisals to be equal and uniform, not merely accurate. Even if HCAD is correct that your home is worth $420,000, if similar homes in your neighborhood sit on HCAD’s rolls at $370,000, you have a legitimate case. The data source is HCAD’s own system, which means they can’t dispute where it came from. In neighborhoods like The Heights and East Downtown, unequal appraisal arguments have become standard practice because comparable properties are frequently assessed at meaningfully different levels. This approach requires more homework but is usually more defensible than relying on outside sales data.
HCAD’s comparable sales and property data is publicly accessible at hcad.org before your hearing. Pull it before you file. Look at properties HCAD considers comparable to yours and see what they’re assessed at per square foot. If the median among your comps is 10 to 15 percent below your own assessment ratio, document the discrepancy with each property’s address and assessed value, and bring that list to your hearing. It doesn’t need to be elaborate. It needs to be specific.
How Houston Compares to Dallas, San Antonio, and Austin
Texas property taxes are high by national standards regardless of which city you’re in. The structural reason is straightforward: Texas has no state income tax, and the services income taxes fund elsewhere are funded here primarily through local property taxation. The Texas Comptroller’s biennial report on state and local taxes documents this trade-off explicitly. You save on income tax; you pay it back through property and sales tax. Whether that trade benefits you depends almost entirely on your income level and your home value — and most people never actually run the numbers.
The differences across Texas metros are real. Using effective rate data on a $400,000 home with a standard homestead exemption applied:
| County/Metro | Effective Rate (approx.) | Est. Annual Tax on $400K Home |
|---|---|---|
| Harris County (Houston) | ~2.0%–2.2% with city/MUD | ~$8,000–$8,800 |
| Dallas County (Dallas) | ~1.9%–2.1% | ~$7,600–$8,400 |
| Bexar County (San Antonio) | ~1.8%–2.0% | ~$7,200–$8,000 |
| Travis County (Austin) | ~1.6%–1.9% | ~$6,400–$7,600 |
(Effective rates reflect combined levy across all taxing entities, with homestead exemption applied. Ranges reflect variability by ISD and special district within each county. Source: Texas Comptroller of Public Accounts property tax data.)
Austin’s position surprises people. Travis County’s effective rate is actually lower than Harris County’s. But Austin home values have risen so sharply over the past decade that the absolute dollar bills often match or exceed Houston’s, depending on the neighborhood. A homeowner with a $750,000 appraised value and a 1.75 percent effective rate pays about $13,125 annually — more than most Houston homeowners pay despite the lower rate. Rate comparisons only make sense anchored to actual home values.
Dallas sits in the middle. Lower effective rates than Houston, but higher home values in many central neighborhoods than comparable Houston locations, often producing similar absolute bills. San Antonio has the lowest effective rates and generally lower home values, leaving its homeowners with the lightest absolute burden in the peer group.
The Payment Calendar, Escrow Traps, and Delinquency Costs
Harris County tax bills are mailed between October and November. Full payment without penalty is due January 31.
On February 1, delinquency starts. The penalty is 6 percent of the unpaid amount, plus 1 percent monthly interest that accrues each month the balance sits unpaid. By July 1, delinquent accounts go to outside collection attorneys, who add a fee of up to 20 percent of the total delinquent amount. A $7,000 bill left unpaid from February through July can acquire $1,400 in attorney fees on top of the accumulating interest and penalties. The costs compound fast, and property can face a tax sale if the delinquency persists past the two-year mark.
The first-year escrow trap catches a disproportionate number of new buyers and deserves explicit attention. When a mortgage servicer sets up your escrow account at closing, it typically estimates the required tax deposit based on the prior year’s bill — the amount the previous owner paid. If the previous owner had a long-standing homestead cap holding their appraised value well below market, their bill may have been thousands of dollars lower than yours will be. Your lender collects monthly escrow deposits based on that estimate, pays the bill in November or January, and when your bill arrives at the reset appraised value, the account is short. The servicer covers the shortage, then notifies you of an escrow deficiency — usually in January or February of your second year — and increases your monthly payment to cover both the shortfall and rebuild the reserve.
This is not a servicer error. It’s a predictable consequence of the appraisal cap reset on sale, and it catches new buyers every year because nobody explains it at closing. The practical fix: check HCAD’s records in your first spring of ownership, see what your appraised value will likely be, calculate your estimated bill using the Comptroller’s transparency site, and alert your servicer if the escrow appears inadequate. An additional payment to the escrow reserve in the fall of your first year can prevent a significant payment shock in year two. If you’re still evaluating whether to buy in Houston right now, current Houston buyer’s market conditions provide useful context on how negotiating leverage affects the total cost of ownership at closing.
Homeowners who qualify for the over-65 or disability exemption may pay their property taxes in four quarterly installments — due January 31, March 31, May 31, and July 31 — without penalty. For retirees managing a fixed income, a large lump-sum bill in January is a real cash-flow problem. The installment option exists specifically for this situation.
To pay and confirm your jurisdictions: go to HarrisCountyTax.org. The Harris County Tax Assessor-Collector’s office handles collection for most entities on the bill, and the site lets you search by address, pay online, and verify which taxing units are attached to your property. If you’re uncertain whether you’re in HISD or another ISD, or whether a MUD appears on your account, this is the authoritative lookup. If your property sits in a jurisdiction where the tax assessor is not Harris County — some smaller cities and MUDs collect independently — your bill may come from a different office. The Comptroller’s transparency site will show you the collecting agent for each entity on your account, and in our moving & real estate coverage we track how these tax structures affect Houston homebuying decisions across different neighborhoods.
Property taxes in Houston and Harris County aren’t a single number, and they were never designed to be. They’re a stack of local decisions — school board budgets, county flood bond programs, MUD debt schedules, city operating levies — applied to an appraised value HCAD recalculates every January 1. The deadlines matter: April 30 for homestead exemption applications, May 15 for protests. Neither one cares that you were busy, and missing them has real consequences. Check the Comptroller’s transparency site for your address, pull HCAD’s comparable data before April, and don’t assume your neighbor in the same ZIP code pays the same rate you do. There’s a reasonable chance they don’t.
