August tax bills are landing in mailboxes across Cedar Park, Pflugerville, Leander, Kyle, and Buda right now. The 2025 MUD levies that will follow buyers for the life of their loans are being adopted at board meetings most residents don’t know are happening.
Why This Is Landing in Your Mailbox Right Now
Every August, a piece of mail arrives that most Austin-area homeowners don’t fully understand. It looks like a tax notice. It references a district with a number instead of a name. It asks for money on top of the Williamson County bill, on top of the Leander ISD bill, on top of whatever else is stacked on that parcel. For buyers who closed in the last year or two, it may be the first time they’ve seen the full accounting.
This is the Municipal Utility District tax bill. Right now, in August and September 2025, MUD boards across Travis, Williamson, and Hays counties are sitting in lightly attended meetings — and I mean lightly attended, as in sometimes a handful of people in a hotel conference room — adopting the rates that will appear on certified tax rolls for the coming year. The rate set this fall becomes part of every mortgage escrow calculation for every home that closes inside those district boundaries between now and next summer.
The problem isn’t secrecy. Texas law requires MUD disclosure in real estate transactions, and the data is publicly available through county appraisal districts and the Texas Commission on Environmental Quality. The real problem: nothing assembles it in plain, usable form for someone who just made an offer on a house in Pflugerville and wants to know what they’re actually agreeing to pay. That’s what this piece is for.
What a MUD Actually Is, and Why Texas Suburbs Are Full of Them
Texas law does not require cities to extend water, sewer, drainage, or road infrastructure into unincorporated land just because a developer wants to build there. If a master-planned community goes up five miles outside Buda’s city limits, the City of Buda owes that development nothing in pipes and lift stations.
Developers solved this problem using a mechanism embedded in the Texas Water Code, specifically Chapter 54. It allows landowners to petition TCEQ to create a Municipal Utility District. The MUD issues bonds — sometimes in multiple series over years — to finance water and wastewater infrastructure, drainage, and related facilities. Those bonds are then retired by taxing the residents who move into the development. The residents pay the debt that funded the pipes under their streets.
Here’s something worth saying clearly: this is not a scam. When you drive through Falcon Pointe in Pflugerville, or Teravista in Round Rock, or Sunfield in Buda, or Wolf Ranch in Georgetown, you’re looking at master-planned communities that exist because a MUD issued bonds and built the infrastructure before the first homeowner arrived. The water runs. The sewage gets treated. Without the MUD mechanism, most of the growth that made Austin the fastest-expanding metro in the country during the 2010s couldn’t have happened on the timeline it did.
The mechanism itself isn’t the problem. The resulting tax obligation is a long-term, compounding line item on a property tax bill, and the real estate sales process has a structural incentive to underemphasize it. New-home salespeople are selling a monthly payment. Resale agents are selling a lifestyle and a square-footage-per-dollar story. Neither conversation naturally leads with: “Your combined effective tax rate in this district will run about a full percentage point higher than a comparable home inside Austin city limits.” Sound familiar?
Austin’s geography made this dynamic nearly inevitable. During the master-planned-community boom of the 2010s, when land was cheap in Hays County and Williamson County and the 183A toll road made north Austin commutes manageable, developer after developer filed MUD petitions with TCEQ. The city’s extraterritorial jurisdiction sprawls into these counties, but ETJ status doesn’t mean a city provides services — it just means the city has a say in land use. The result is a dense ring of MUD-financed subdivisions now surrounding the metro, many of them still actively issuing bonds to accommodate new phases.
What a MUD Levy Actually Costs on a $450,000 Home
Here’s the number most readers came here to find.
A MUD tax rate of $0.85 per $100 of assessed value on a $450,000 home produces an annual MUD levy of $3,825. Divide that across 12 months: $318.75 added to the escrow portion of a mortgage payment. On a $450,000 purchase with 10 percent down, that single line item adds more to the monthly housing cost than many buyers spend on car insurance. Let that sit for a second.
To see why this matters at the transaction level, consider a stacked tax table for a representative suburban home in a MUD district. The table below uses the range of rates found in Travis and Williamson county records for each entity type. All rates must be verified against 2025 certified CAD data before any financial decision.
| Taxing Entity | Illustrative Rate Range (per $100 AV) | Annual Levy Range on $450K Home |
|---|---|---|
| Local school district | $0.92–$1.04 | $4,140–$4,680 |
| Travis/Williamson/Hays County | $0.30–$0.40 | $1,350–$1,800 |
| City (Cedar Park, Kyle, Pflugerville, etc.) | $0.30–$0.45 | $1,350–$2,025 |
| MUD District | $0.55–$0.95 | $2,475–$4,275 |
| Combined Estimate | ~$2.10–$2.85 | ~$9,450–$12,825 |
Now compare that to a $450,000 home inside Austin city limits, no MUD, in a neighborhood served by Austin ISD:
| Taxing Entity | Illustrative Rate (per $100 AV) | Annual Levy on $450K Home |
|---|---|---|
| Austin ISD | $0.97 | $4,365 |
| Travis County | $0.30 | $1,350 |
| City of Austin | $0.45 | $2,025 |
| Total | $1.72 | $7,740 |
Suburban homes in active MUD districts carry combined effective tax rates roughly 35–50 percent higher than comparable properties inside Austin city limits. Over 30 years, even before accounting for annual rate changes, that gap is substantial. A buyer choosing between a home in a Pflugerville MUD district and a home in central Austin isn’t actually comparing the same monthly payment. The difference — before the mortgage calculator ever enters the picture — can run several hundred dollars a month. That’s a car payment. For a fuller breakdown of how combined rates vary across the metro, our home & property coverage tracks these costs throughout the year.
All rates above are illustrative, drawn from the general range of rates in publicly available Travis and Williamson county appraisal district records. Verify current adopted rates for any specific address through the relevant county CAD and TCEQ records before making any financial or purchasing decision.
Six Suburban Districts, Side by Side
The following comparison covers six named districts representing the MUD concentration around the Austin metro. Rate ranges reflect publicly reported figures from county appraisal district records and TCEQ annual reports, calculated against a $450,000 assessed value. Independently verify all rates against 2025 certified records before closing.
Travis County MUD No. 17 (Pflugerville / Manor area)
One of the older growth-era districts in eastern Travis County, No. 17 covers residential development in the Pflugerville and Manor corridors along Dessau Road and the Pflugerville fringe. Pflugerville is consistently underrepresented in consumer coverage of MUD costs despite having some of the highest MUD concentrations in the metro — genuinely hard to explain given how much the area has grown over the past decade. Rate range observed in recent years: $0.65–$0.90 per $100 AV. At $0.85, the annual levy on a $450K home runs approximately $3,825.
Williamson County MUD No. 19 (Cedar Park / Leander area)
Covers master-planned residential development in the fast-growing Cedar Park and Leander corridor, north of Ronald Reagan Boulevard along US-183 and 183A. Rate range: $0.55–$0.75 per $100 AV. At $0.65, the annual levy on a $450K home is approximately $2,925 — toward the lower end of what you’ll encounter in the metro’s active growth ring.
Williamson County MUD No. 22 (Leander / Liberty Hill area)
Serves newer development phases pushing into the Liberty Hill growth zone, near the 29/183 junction. Bond issuance here is more recent than in No. 19, and it shows in the rate. Range: $0.70–$0.95 per $100 AV. At $0.90, annual levy on a $450K home is approximately $4,050. Districts still issuing bonds in active corridors like this one won’t be cutting rates anytime soon — each new bond series extends the debt service obligation another 20 to 30 years.
Hays County MUD No. 7 (Kyle / Plum Creek area)
Plum Creek is one of the most recognizable master-planned communities in Hays County, and its MUD carries the infrastructure financing for the development’s original buildout. Kyle’s population has roughly doubled in a decade, yet its MUD districts have barely appeared in regional consumer coverage — a gap this publication intends to keep closing. Rate range: $0.55–$0.80 per $100 AV. At $0.70, annual levy on a $450K home is approximately $3,150.
Hays County MUD No. 6 (Buda / Garlic Creek area)
Garlic Creek is a well-established Buda community near FM 967 and Whispering Hollow. The MUD has been in place long enough to have retired some original bond series, and the rate reflects that — though operations and maintenance components persist indefinitely. Rate range: $0.60–$0.85 per $100 AV. Buda MUDs layer on top of Hays CISD and City of Buda levies, and Buda’s active annexation activity means district boundaries can shift. Verify current boundaries and rate at Hays CAD before closing.
Travis County MUD No. 12 (Del Valle / Southeast Austin ETJ)
Covers development in the southeast Travis County ETJ, east of the 183 South and SH-71 junction. This growth zone gets considerably less attention than the northern and southern corridors but carries comparable MUD structures. Verify current adopted rate against Travis CAD directly — this district’s rate has moved in recent years as development phases have progressed.
The Transaction-Level Surprise
Title officers who process closings across Williamson and Hays counties describe a recurring pattern. Buyers arrive having calculated their payment based on the school district rate and the county rate, using an online calculator. Then the tax certificate comes back with a MUD line — sometimes close to a full dollar per hundred — and they assume an error has been made. It hasn’t. The MUD levy is simply part of the transaction that wasn’t discussed.
The seller disclosure form creates legal compliance without creating financial clarity. The form states that a property is in a MUD district. It does not state that the MUD will add hundreds of dollars to the monthly escrow payment, or that the obligation persists for decades, or that districts still issuing bonds are unlikely to see rate reductions anytime soon. Legal compliance and genuine disclosure are different things, and this is a significant gap. Buyers who want to understand what Austin builders are actually offering to offset these costs in active MUD corridors should read what Austin builders are actually offering right now to move suburban inventory.
MUD, PID, or WCID: The Alphabet Soup on Your Tax Certificate
Not every special district levy on an Austin-area tax certificate is a MUD. Buyers in several specific communities are encountering different structures with different legal mechanics. Confusing them leads to the wrong questions at closing.
A MUD operates under Texas Water Code Chapter 54. It has an elected board that issues bonds and levies a tax rate against assessed value to retire those bonds and fund operations. The rate appears as a separate line on your property tax statement. Board elections are technically open to all registered voters within the district, though turnout is often measured in double digits.
A PID levies a per-parcel assessment rather than an ad valorem rate. The assessment is often fixed in dollar terms or calculated on a per-square-foot basis, established by the city or county that created the district. Easton Park in southeast Austin is a local example. PID assessments show up differently on a tax certificate — typically as a separate assessment line rather than a rate-based tax. When your home’s appraised value increases, your PID assessment may not change. Your MUD levy almost certainly will.
A WCID (Water Control and Improvement District) is an older statutory form predating the MUD structure. WCIDs appear in parts of Williamson County and some older developed areas, including parts of Georgetown. They function similarly to MUDs in practical terms — issuing bonds, levying taxes — but their statutory framework differs and their financial disclosures are filed through a different regulatory pathway.
A LID (Levee Improvement District) is rare in the Austin metro but relevant in some low-lying areas near South Austin and along flood-prone corridors. If you’re looking at property near Onion Creek or other drainage-sensitive areas, ask about it specifically.
Any of these can appear on a tax certificate. Only a title search, a CAD parcel lookup, or a direct call to the county appraisal district can tell you which type applies to a specific address. The buyer protections differ. The long-term rate trajectory differs. The way the levy responds to rising property values differs. They’re not interchangeable, even though they all look like mysterious lines on the same page.
How to Look Up Any Address Before You Make an Offer
You don’t need a title officer or an attorney to determine whether an address sits inside a MUD district. Two browser tabs, three minutes.
Travis County Appraisal District (traviscad.org): Search by address. Pull up the parcel and navigate to the “Taxing Entities” or “Jurisdictions” tab. Every taxing entity attached to that parcel is listed — including any MUD, WCID, or PID — alongside the adopted tax rate for each entity.
Williamson Central Appraisal District (wcad.org): Same process. Cedar Park and Leander parcels frequently show Williamson County MUD entries here.
Hays Central Appraisal District (hayscad.com): Kyle and Buda parcels. The interface differs slightly from Travis and Williamson, but the taxing entities tab works the same way.
Look for any entity with “MUD,” “WCID,” “LID,” or “Water District” in its name. Note the adopted rate per $100 of assessed value. Multiply that rate by the home’s assessed value divided by 100 for the annual levy. Divide by 12 for the monthly escrow impact.
If the parcel doesn’t show a water district entity, that’s a good sign — not a guarantee. Some newer districts or recently annexed parcels can lag in CAD records. Cross-reference with the TCEQ Water District Search to confirm.
The TCEQ database links to each district’s most recent annual report: a public document filed by the district’s board and audited by an independent accountant. In that report, look for the current adopted tax rate, the district’s outstanding bonded indebtedness, the debt service schedule, and the operations-and-maintenance portion of the rate. The O&M portion matters because it persists even after the original bonds are retired — it’s your permanent floor. Annual reports are downloadable as PDFs and typically run one cycle behind the current adopted rate, so use the CAD parcel search for the most current figure and the TCEQ report to understand the district’s financial position. Neither source requires an account or a fee.
Do MUD Taxes Ever Go Away? The Honest Answer
This is the question buyers most want an optimistic answer to.
MUDs are created to retire specific bond issuances, typically structured as 20-to-30-year obligations. As bonds mature, the debt service component of the rate — often the largest single component — can decline. In stable, fully built-out districts that haven’t issued new bonds in years, this reduction actually happens. Steiner Ranch in Travis County is a local example: the district has matured significantly from its early bond-heavy years, and residents have seen the debt service portion of their levy decline as original infrastructure bonds aged toward retirement. Some Pflugerville-area districts established in the mid-to-late 1990s have followed a similar path.
But in communities still absorbing new development phases, the math reverses. A MUD covering the first 500 lots of a 2,000-lot planned community will almost certainly issue additional bonds to fund infrastructure for phases two, three, and four. Each new issuance resets the debt clock. The district may be 15 years into its original bond series — rate declining, residents feeling good about it — then it votes to issue a new series for the next section, pushing the rate back up or holding it flat for another decade. For buyers in the active growth corridors — Leander pushing toward Liberty Hill, Kyle expanding south and west, Buda’s northern and eastern edges — the realistic 30-year projection is that the MUD rate won’t decline significantly until development within the district boundary is essentially complete.
The question to ask is simple: is the district still issuing new bonds? The TCEQ annual report’s debt schedule will tell you. If the answer is yes, treat the MUD rate as a long-term fixed cost, not a temporary surcharge.
One additional scenario: municipal annexation. When a city annexes territory, MUD status can change. In some cases, the city assumes the district’s debt and the MUD levy rolls into the city’s tax rate. In others, the MUD persists after annexation until its outstanding bonds are retired. Ask specifically about any suburban district you’re evaluating — particularly in Buda, where annexation activity has been active enough that district boundaries have shifted in recent years.
What to Ask Your Agent and Title Officer Before You Sign
The Texas property code requires sellers to disclose MUD membership, and most standard sales contracts include a MUD addendum. But the disclosure creates legal compliance, not financial clarity. Here are the specific questions that close that gap.
What is the current adopted tax rate for this address? Don’t accept a general answer. Get the rate, in dollars per $100 of assessed value, for every taxing entity on the parcel, including the MUD. If your agent can’t tell you, it’s on the CAD parcel page, accessible in under two minutes.
Is the district still carrying active bond debt? A district with no outstanding bonds is a very different financial obligation than one with 20 years of debt service remaining. The TCEQ annual report discloses total outstanding debt.
Has the district issued new bonds in the last five years? Recent issuance is the clearest indicator the rate won’t be declining soon.
What is the operations-and-maintenance portion of the rate? This is the floor below which the rate cannot fall even after all bond debt is retired. It’s disclosed in the TCEQ annual report and is your permanent minimum levy.
Will this district eventually be annexed by the city, and what happens to the MUD levy if it does? Your agent or title officer may not know with certainty — that’s fine. A city’s annexation plans for surrounding ETJ territory are often on record in comprehensive plans and ETJ agreements. A direct inquiry to the relevant city planning department is worth making.
Does the property carry a PID or WCID instead of, or alongside, a MUD? Some parcels in communities like Easton Park carry a PID alongside standard county, city, and school rates. The structure matters because the buyer protections and rate trajectories differ.
One thing that almost never comes up in these conversations: MUD boards are elected bodies with extremely low voter turnout. In many district elections, a handful of votes determines who sits on the board — and by extension, who adopts the tax rate each year. Residents who want to exercise influence over their MUD levy have considerably more power than they typically use.
MUD levies are property taxes and are deductible on Schedule A of your federal return. Confirm your specific situation with a tax professional before factoring deductibility into any after-tax comparison you’re running between suburban and urban scenarios.
The August tax cycle is a useful moment to have this conversation — not because the bill surprises current owners who’ve been paying it for years, but because the rates being adopted right now will become real obligations for buyers closing this fall and winter. Anyone making an offer on a home in Cedar Park, Pflugerville, Leander, Kyle, or Buda should spend three minutes on a CAD property search before that offer goes in. The information is public, it’s free, and it’s sitting there waiting.
