Where You Live Shapes What You Pay
One of the most common questions we hear from buyers moving around the Lake Houston area is some version of “why is the tax bill on this house so different from that one?” It’s a great question, and the answer usually comes down to three things: which county you’re in, whether you’re inside a city’s limits or in the unincorporated county, and whether the neighborhood sits inside a Municipal Utility District, or MUD. None of these are good or bad on their own — they’re trade-offs, and understanding them turns a confusing tax bill into a clear, comparable number you can plan around.
This guide walks through all three. We’ll look honestly at the pros and cons of being inside the City of Houston versus unincorporated Harris County, break down exactly what your property tax bill is made of (and cite current rates), compare Harris and Montgomery County, and demystify MUD taxes — what they are, what they fund, and what to expect if your home is in one. Our goal isn’t to talk you into or out of anything; it’s to make sure you know what you’re buying. For a deeper dive on the MUD question specifically, see our companion guide, MUD taxes and your home purchase.
Kingwood, Annexation & the Muscle of the City
Longtime residents remember Kingwood before it was annexed into the City of Houston in the mid-1990s — and there’s real nostalgia for those days. The community had a tight-knit, self-governed feel, and some of what made Kingwood special in that era is genuinely missed. It’s fair to say the trade-offs of annexation are still debated at more than a few dinner tables.
But pull the camera back and there have been definite wins. A community the size of Kingwood needs serious infrastructure muscle, and being part of the City of Houston has brought resources to bear on the challenge that matters most here: drainage and flood mitigation. After the hard lessons of recent storms, having the city’s engineering and capital behind large-scale drainage work has been critical — the kind of project that’s simply hard to fund at a neighborhood scale.
The honest ledger has entries on both sides. EMS response, once run by beloved local volunteers, feels less personal than it did, and city police coverage can be stretched thinner across a big service area than many residents would like. Those are real. But so are the wins — the infrastructure investment, the drainage progress, and the services a major city can provide. The point of this section isn’t to settle the debate; it’s to show that “city vs. county” is a genuine set of trade-offs, not a simple better-or-worse.
City of Houston vs. Unincorporated Harris County: The Trade-Offs
When a home sits inside the City of Houston (as Kingwood does), residents pay a city property tax and, in return, receive full municipal services — city police and fire, code enforcement, libraries, parks, and city-run water, drainage, and capital projects. In unincorporated parts of the county, there’s no city property tax line at all, which can mean a lower headline rate; in exchange, some services are thinner or provided differently — sheriff’s patrol and constables rather than a city police department, ESD-based fire and EMS, and utilities delivered through MUDs or other special districts rather than a city.
City vs. Unincorporated — At a Glance
What Your Property Tax Bill Is Actually Made Of
Your annual property tax isn’t one tax — it’s a stack of separate rates from every taxing entity that serves your address, each expressed per $100 of taxable value. For a typical Kingwood home inside the City of Houston and Humble ISD, the stack in 2025 looks roughly like this: Humble ISD $1.1052, City of Houston $0.5192, Harris County $0.3853, Harris Health (the county hospital district) $0.1876, Harris County Flood Control $0.0497, the Port of Houston $0.0059, and the county Department of Education $0.0048. Add those up and you’re around $2.26 per $100 of taxable value — before any homestead or other exemptions, which lower what you actually pay.
Two things jump out. First, the school district is by far the largest slice — nearly half the bill — which is true almost everywhere in Texas. Second, notice there’s no MUD line in that Kingwood example, because most of Kingwood is on City of Houston utilities. In a neighborhood served by a MUD, that MUD rate would be added to the stack (and, as we’ll see, it’s designed to shrink over time). Encouragingly for local buyers, Humble ISD has actually held or trimmed its rate in recent years, and the City of Humble and Harris County entities publish their rates openly each fall.
Harris County vs. Montgomery County
Cross into Montgomery County — think Porter, New Caney, Conroe, and the master-planned communities north of Kingwood — and the math shifts. Montgomery County’s own rate (about $0.3770/$100) is similar to Harris County’s, and a typical Conroe-area homeowner’s all-in rate lands around $1.91/$100 before a MUD. Buyers sometimes assume “Montgomery County = lower taxes,” and the base county math can be favorable — but the MUD layer is where the real variation lives.
Montgomery County has over 150 MUDs, and their rates swing widely. In mature districts like much of The Woodlands, MUD rates can be as low as $0.07–$0.17 per $100. In newer master-planned communities still paying off fresh infrastructure bonds, a MUD can add anywhere from $0.50 to more than $1.00 per $100 — in a few districts (Woodforest is a known example) the MUD rate alone can reach $0.83 or higher. That’s the grain of truth behind the comment that “MUD taxes can be second only to school taxes”: in a brand-new MUD community, the MUD really can be one of the largest single line items on the bill. The good news, covered below, is that those rates are the highest they’ll ever be on the day you buy — they fall from there.
MUD Taxes: What They Are & What to Expect
A Municipal Utility District is a limited-purpose local government created under Texas law to finance and deliver water, wastewater, drainage, and infrastructure to a community that a city or county couldn’t build fast enough on its own. When a developer opens a new neighborhood, a MUD issues tax-exempt bonds to pay for the underground pipes, treatment plants, drainage, and often roads and parks. Residents then repay those bonds through a MUD property tax, set publicly each year by an elected five-member board of local residents, with annual independent audits and oversight from the Texas Commission on Environmental Quality (TCEQ).
Here’s the part that surprises most buyers, and it’s genuinely good news: MUD tax rates start high and decline over time. Early on, a handful of homeowners are carrying the cost of brand-new infrastructure; as the bonds are paid down and more homes are built to share the load, the rate comes down — often dramatically. Across Greater Houston, the weighted-average MUD rate fell from about $0.96 per $100 in 1988 to a historic low of roughly $0.55 by 2021 — which that year was actually a hair below the City of Houston’s own rate. A MUD, in other words, isn’t automatically “extra” tax; it’s often comparable to what a city resident already pays, and it keeps falling as the district matures.
So what should you expect if you’re buying in a MUD? Ask three questions: what is the MUD’s current rate, how has it trended over the last several years, and how far along is the district in paying off its debt? A newer MUD with a high rate has room to fall; a mature one may already be low. Either way, the MUD funds the water you drink and the drainage that keeps your street dry — real value — and knowing its trajectory lets you fold it into your budget with no surprises.

6 Things to Check Before You Buy — Anywhere
Confirm the County & City Status
Know whether the home is in Harris or Montgomery County, and whether it’s inside a city’s limits or unincorporated — it drives both your services and your tax stack.
Get the Full Tax Rate Stack
Ask for every taxing entity on the bill — school district, county, city, hospital, flood control, college, and any MUD — not just the headline number.
Check the MUD Status & Rate
If there’s a MUD, get its current rate and its trend over the past several years, and ask where it is in paying off its bonds.
Apply the Exemptions
Homestead and other exemptions can meaningfully lower what you actually pay — make sure your estimate reflects them, especially on school taxes.
Weigh the Services You’ll Use
City police and fire, county sheriff and ESDs, drainage muscle, libraries, parks — value the services against the rate, not the rate alone.
Budget the All-In Monthly Number
Fold the true annual tax (MUD and all) into your monthly payment so the home you love is a home you can comfortably own.
Frequently Asked Questions
Is it better to be in the City of Houston or unincorporated county?
Neither is universally better — it’s a trade-off. Inside the city you pay a city tax but get full municipal services and big-project drainage muscle; unincorporated areas skip the city tax but often have a MUD and different service providers. The right answer depends on the specific home, its total tax stack, and the services you value.
Why is Kingwood in the City of Houston?
Kingwood was annexed into the City of Houston in the mid-1990s. Being part of the city has brought municipal services and, importantly, city engineering and capital to major drainage and flood-mitigation work — a real benefit for a low-lying area — alongside trade-offs like less-personalized EMS than the old volunteer model.
What makes up my property tax bill?
A stack of separate rates from every entity serving your address: the school district (usually the largest, ~half the bill), the county, the city (if you’re in one), the hospital district, flood control, a community college, and any MUD. For a typical Kingwood home in 2025 that’s roughly $2.26 per $100 of taxable value before exemptions.
Are property taxes lower in Montgomery County?
The base county math can be similar to or a bit lower than Harris County, but the MUD layer drives most of the variation. Mature Montgomery County MUDs can be very low, while newer master-planned communities can add $0.50 to $1.00+ per $100 while their bonds are being repaid. Always compare the all-in rate, not just the county.
Do MUD taxes go up or down over time?
Down, as a rule. MUD rates start high to fund brand-new infrastructure, then decline as the bonds are paid off and more homes share the cost. The Greater Houston weighted-average MUD rate fell from about $0.96 in 1988 to roughly $0.55 by 2021, a historic low. Our Understanding MUDs guide charts the full trend.
How do I find out if a home is in a MUD?
Ask your agent and check the appraisal district record for the property, which lists every taxing entity. If there’s a MUD, you can look up its current rate and recent history — and Texas law also requires sellers to provide a MUD notice disclosing the district and its rate. When you’re ready to run the numbers on a specific home, reach out and we’ll pull the full tax picture together.
A quick note: This is general educational information, not tax or legal advice. Tax rates change every year and vary by exact address. Always confirm a specific property's current rates and MUD status with the county appraisal district before you buy.
