Buda Adopted a New Tax Rate This Week. It's Not the One That Will Move Your Payment.

On September 15, 2026, the Buda City Council voted to set the city's property tax rate at $0.3895 per $100 of taxable value for fiscal year 2027, up from $0.3576 the year before. If you're watching Buda listings and that number just crossed your feed, here's the part that matters more for your actual offer: the city rate is the smallest, most stable line on a Buda tax bill. The number that actually separates two identical listings by thousands of dollars a year almost never makes the news, because it isn't set by a city council at all. It's set by a Municipal Utility District, and in a fast-growing community like Buda, there are several of them, each with its own board, its own bond schedule, and its own rate.

The Number Everyone Is Talking About

Buda's city tax rate has climbed three years running. It sat at $0.3395 per $100 in fiscal year 2025, rose to $0.3576 for fiscal year 2026, and now stands at $0.3895 for fiscal year 2027. City Manager Micah Grau has framed each increase as a response to rising costs rather than aggressive new spending. Ahead of last year's adoption he put it plainly: "Rising service costs required us to make careful choices." The city has also pointed to $89.9 million in voter-approved 2021 bonds for transportation and park work as a factor pushing the debt-service portion of the rate higher even as home values have softened.

Here's what that history actually costs a homeowner. Between fiscal 2025 and fiscal 2026, the average Buda household saw its city tax bill move from about $1,457 to about $1,471, a swing of roughly $14, because a drop in average home value largely offset the higher rate. For fiscal 2027, city reporting put the year-over-year change at closer to $96, from about $1,378 to about $1,474 on a median taxable value near $383,550. Even at the high end, you're talking about a difference measured in tens of dollars a month, spread across an entire city.

That's worth knowing. It is not worth basing a housing decision on.

The Line That Doesn't Make Headlines

Buda's median effective property tax rate, blending city, county, and school levies, runs in the neighborhood of 1.6 to 1.9 percent depending on which county slice of Buda a home sits in, since the city straddles both Hays and Travis county lines. That's the number most cost calculators will hand you if you type in a Buda address.

It's also the number that quietly stops applying the moment a home sits inside one of Buda's Municipal Utility Districts. Sunfield, the roughly 2,700-acre master-planned community off I-35 that has become one of Buda's largest sources of new construction, is served by two separate districts, Sunfield Municipal Utility District No. 1 and Sunfield Municipal Utility District No. 3. Each is its own political subdivision under Texas law, with its own board and its own authority to levy a tax and issue bonds for the water, sewer, and drainage infrastructure that had to go in before any of those homes could be built. Neither district's tax shows up in the city's rate. Both stack on top of it.

The result is a combined effective rate across Hays County, the City of Buda, Hays CISD, and Sunfield's district taxes that has run above 2.6 percent every year since 2021, and sat at roughly 2.73 percent for the 2025 tax year. Compare that to the roughly 1.62 percent blended median for Buda as a whole, and the gap is over a full percentage point. On a $400,000 assessed value, that's the difference between a tax bill in the $6,500 range and one closer to $10,900, an added cost of roughly $4,400 a year that never appears in the list price and rarely appears in the listing description.

The city rate is a single line that moves a few hundredths of a point a year. Sunfield's combined rate is a stack of five or six taxing entities that moves for entirely different reasons, and that's the number that decides what a specific address actually costs to hold.

Why the MUD Rate Doesn't Just Go Down

The standard advice about MUDs is that the rate declines over time as a district pays down its original bonds and adds more rooftops to spread the debt across. That's true for a single-phase district that finishes construction and stops issuing new debt. It is not automatically true for a multi-phase, still-growing community.

Sunfield's own effective rate history makes the point. It ran 2.9262 percent in 2021, dropped to 2.6106 percent by 2023 as early bonds amortized, then climbed back to 2.7269 percent by 2025. A district that's still building out new sections keeps authorizing new bonds for the infrastructure those new sections need, which can push the rate back up even while the original debt is being retired in older phases. A buyer who assumes "it'll come down eventually" is making a bet on a development timeline they haven't seen, not a mathematical certainty.

What To Actually Check Before You Write an Offer

The list price and the county's advertised median rate will tell you almost nothing about what a specific Buda address costs to own. Before you write an offer, or before you counsel a client who's about to:

• Pull the actual tax certificate for the property, not a neighborhood estimate. Hays County and Travis County both maintain searchable databases for exactly this purpose.
• Ask whether the lot sits inside a MUD, a Water Control and Improvement District, or a Public Improvement District, and get the current adopted rate for that specific entity, not a citywide average.
• Ask whether the district has additional phases planned. A district still building infrastructure for future sections is more likely to see its rate move against you than one that finished construction years ago.
• Confirm which portion of a stacked bill your homestead exemption actually reduces. It generally applies to city, county, and school levies. It typically does not reduce a MUD's portion of the bill, since the district is its own independent taxing authority.

None of this shows up on a listing sheet. All of it shows up on the tax certificate, and all of it is knowable before you're under contract.

A Few Questions Worth Asking Directly

Does a homestead exemption lower my MUD tax? Usually no. The general homestead exemption reduces the taxable value used for city, county, and school district levies. A MUD is an independent taxing entity and typically taxes the full assessed value unless that specific district has adopted its own local exemption, which varies district by district.

Will my MUD rate go down over time? Often, but not automatically. Rates tend to fall as a district retires debt and its tax base grows. In a community still adding phases, like Sunfield, new bonds for new sections can offset that decline, which is exactly what its rate history shows.

Is every new Buda neighborhood inside a MUD? No. Older, in-city sections of Buda may fall entirely under city, county, and school taxation with no separate district at all. Newer master-planned development, where a builder had to fund water and sewer infrastructure before the city extended service, is far more likely to carry one.

The city's new rate will show up in next year's Truth in Taxation notice and it's a legitimate thing to track. But if you're comparing two Buda addresses this fall, the number worth asking about isn't the one the council just voted on. It's the one sitting quietly on a separate line of the tax certificate, tied to a district board most buyers never knew existed until they saw their first bill.

If you're weighing two Buda neighborhoods and want the real number behind the list price, not just the county average, Courtney Unangst can pull the actual tax stack for any address you're considering before you write an offer.
