This post is part of the Complete Guide to Buying a Home in Katy, Fulshear, Cypress & Richmond — your start-to-finish resource for navigating the west Houston housing market in 2026.
If there is one topic that catches Katy-area home buyers off guard more than any other, it is property taxes. Texas has no state income tax, which sounds like a win — and it is — but the trade-off is that property taxes in the Houston metro are among the highest in the country. And if your home sits inside a Municipal Utility District, commonly known as a MUD, your total tax bill can be significantly higher than you expected.
Bobby Mohebbi and the Mohebbi Realty Group team review the exact property tax rate for every home their buyers consider. Not the community average. Not the county average. The specific, lot-level rate that will show up on your monthly mortgage payment. This guide explains how property taxes work in the Katy, Fulshear, Cypress, and Richmond area, what MUD districts are, why they exist, and exactly how they affect your bottom line.
How Property Taxes Work in Texas
Texas property taxes are calculated by multiplying your home's taxable value by the combined tax rate of every taxing entity that covers your property. Unlike most states, Texas does not have a single, unified property tax rate. Instead, your tax bill is the sum of multiple overlapping taxing authorities, each with its own rate.
A typical Katy-area homeowner pays property taxes to some combination of the following entities: the school district (Katy ISD, Cy-Fair ISD, or Lamar CISD), the county (Harris, Fort Bend, or Waller), any applicable city (City of Katy, for homes within city limits), one or more Municipal Utility Districts, and in some cases additional special districts for drainage, levee protection, or regional water authority fees.
Each of these entities sets its own rate, expressed as dollars per $100 of taxable value. Your total rate is the sum of all the individual rates. On your annual tax bill — which arrives separately from each entity — you will see a line item for every taxing authority with its own rate and dollar amount.
The formula is straightforward. Take your home's appraised value, subtract any exemptions (such as the homestead exemption), and multiply by the total tax rate. For example, a home appraised at $400,000 with a $100,000 homestead exemption has a taxable value of $300,000. At a total tax rate of 3.0%, the annual property tax bill is $9,000 — or $750 per month.
What Is a MUD District and Why Does It Exist?
A Municipal Utility District is a special-purpose local government entity created under Texas law to finance, build, and maintain essential infrastructure for developing communities. In practical terms, a MUD is the mechanism that makes most new construction in the Katy, Fulshear, Cypress, and Richmond corridors possible.
When a developer builds a new master-planned community, someone has to pay for the infrastructure — the water lines, sewer systems, drainage facilities, roads, and sometimes parks or recreational amenities. Rather than paying the full cost upfront (which would make the homes significantly more expensive), the developer forms a MUD. The MUD issues municipal bonds to finance the construction of that infrastructure. Those bonds are then repaid over time through property taxes collected from the homeowners who live within the district.
The MUD is governed by a board of directors, typically elected by property owners within the district. The board sets the annual tax rate, manages the budget, oversees the utility system, and makes decisions about ongoing maintenance and future improvements. MUDs operate under the regulatory authority of the Texas Commission on Environmental Quality.
For homeowners, the MUD tax shows up as a separate line item on your property tax bill, in addition to your school district, county, and city taxes. You will also receive a separate monthly utility bill from the MUD for water, sewer, and trash service.
MUDs are extremely common in the west Houston suburbs. If you are buying new construction in a master-planned community in Katy, Fulshear, Hockley, or Richmond, your home almost certainly sits within a MUD. Bobby Mohebbi identifies the specific MUD for every lot his buyers consider and reviews the current tax rate, outstanding bond debt, and rate history before an offer is made.
How MUD Taxes Affect Your Monthly Payment
This is the section that matters most for your budget. The difference between a home in a lower-rate MUD and a home in a higher-rate MUD can be hundreds of dollars per month — even on identical purchase prices.
Here is a concrete comparison using two real scenarios in the Katy area.
Scenario A is an established home in Cinco Ranch with a total effective property tax rate of approximately 2.5%. On a home valued at $400,000 with a homestead exemption reducing the taxable value to roughly $300,000, the annual property tax bill is approximately $7,500 — or $625 per month.
Scenario B is a new construction home in Sunterra with a total effective property tax rate of approximately 3.5%. On the same $400,000 value with the same homestead exemption, the annual property tax bill is approximately $10,500 — or $875 per month.
The difference is $250 per month, or $3,000 per year, on the same priced home. Over ten years, that is $30,000 in additional property taxes.
On a $400,000 home, the gap between a 2.5% total rate and a 3.5% total rate is equivalent to roughly $50,000 in lost purchasing power. A buyer who was pre-approved for a $400,000 home based on a standard tax estimate may find that they can only comfortably afford a $350,000 home once the actual MUD-inclusive tax rate is factored in.
This is exactly why Bobby Mohebbi insists on identifying the exact tax rate for every property before a buyer moves forward. The difference between one section and another within the same community can amount to thousands of dollars per year.
What Tax Rates Look Like Across the Katy Area
Tax rates in the west Houston corridor vary widely depending on your specific location, county, school district, and MUD assignment. Here is a general guide to what you can expect across the communities Bobby Mohebbi works in.
Established communities like Cinco Ranch generally carry total effective tax rates in the 2.3% to 2.8% range. These communities have been paying down their MUD bond debt for decades, which means the MUD portion of the tax rate has decreased significantly over time. Some sections of Cinco Ranch have MUD rates below $0.30 per $100 of valuation.
Seven Meadows and Grand Lakes fall in a similar range, typically 2.3% to 2.8%, benefiting from years of bond repayment in their respective MUD districts.
Newer communities like Sunterra carry total effective tax rates in the 3.3% to 3.6% range. Because the community is still relatively new, the MUD bond debt is at its highest level and the corresponding tax rate reflects that. As bonds are repaid over time, the rate is expected to decrease — but that process takes 20 to 30 years.
Elyson's tax rates vary by section but generally fall in the 2.8% to 3.5% range depending on the specific MUD assignment. Some sections carry higher rates than others, making lot-level due diligence essential.
Cross Creek Ranch tax rates vary depending on whether the home is in Fort Bend County or Harris County and which MUD district applies. Rates generally range from 2.5% to 3.2%.
Bridgeland in Cypress has a layered fee structure that includes both property taxes and HOA-related conveyance fees. Total effective tax rates generally range from 2.8% to 3.3%, plus a 0.5% conveyance fee charged at resale.
These ranges are general guidelines. The actual rate for any specific property depends on the exact MUD, county, school district, and any additional special districts that apply. Bobby Mohebbi pulls the precise rate for every address.
The Good News: MUD Rates Can Decrease Over Time
One of the most important things to understand about MUD taxes is that they are not permanent at their initial level. MUD tax rates primarily pay off infrastructure bonds. Once those bonds are retired — typically over a 20 to 40-year period — the debt service portion of the MUD tax drops significantly or disappears entirely. What remains is a smaller operations and maintenance rate that covers the ongoing cost of running the utility system.
There are real examples of this across the Houston area. Older MUD districts in established communities have seen their rates decline by 50% to 75% from their original levels as bonds were retired. Some districts that were originally assessed at $1.50 per $100 in the 1970s and 1980s now carry rates below $0.40 per $100.
This means that buyers who purchase in a newer community with a higher MUD rate today are effectively paying the cost of brand-new infrastructure. Over time, as the bonds are repaid, the tax rate should decrease. It is a front-loaded cost that eventually normalizes — similar to a car payment that ends.
However, MUD rates can also increase in certain situations. If the district issues new bonds for additional infrastructure phases or improvements, the rate may go up. If property values in the district decline, the rate may increase to maintain the same dollar amount of revenue. Bobby Mohebbi reviews the MUD's outstanding bond schedule and rate history to help buyers understand the trajectory for their specific district.
The Homestead Exemption: Your Most Important Tax Tool
If you are buying a primary residence in Texas, the homestead exemption is the single most important tax reduction available to you. Filing for a homestead exemption reduces the taxable value of your home, which directly lowers your property tax bill across every taxing entity.
In 2026, the Texas homestead exemption reduces your taxable value by $100,000 for school district taxes. Many counties and MUDs offer additional homestead exemptions on top of the state-level school exemption. Harris County offers a 20% homestead exemption. Fort Bend County and individual MUDs may offer their own percentage or dollar-amount exemptions.
You must file for your homestead exemption with your county's appraisal district after closing on your home. It is not automatic. Filing is free, and you only need to do it once — it remains in effect as long as you live in the home. Bobby Mohebbi reminds every buyer to file their homestead exemption after closing, because failing to do so can cost you hundreds of dollars per month in unnecessary taxes.
Additional exemptions are available for homeowners who are 65 or older, disabled, or disabled veterans. These exemptions provide additional reductions in taxable value and, in the case of seniors, allow for a freeze on the school district portion of your tax bill.
MUD Taxes vs HOA Dues: Understanding Both
Buyers sometimes confuse MUD taxes with HOA dues, or assume that one replaces the other. They are separate charges that serve different purposes, and in most Katy-area communities, you will pay both.
MUD taxes are government property taxes that fund infrastructure — water systems, sewer, drainage, and roads. They are collected by the county tax assessor and included in your annual property tax bill. They are typically escrowed into your monthly mortgage payment.
HOA dues are private fees collected by your homeowners association to fund community maintenance, amenity upkeep, landscaping of common areas, and community programming. They are billed separately, usually on a monthly, quarterly, or annual basis.
In a typical Katy-area master-planned community, you will pay property taxes (including any MUD component) plus HOA dues plus a monthly water and sewer utility bill from the MUD. All three are real costs that should be factored into your monthly budget before you make an offer.

How to Research the Tax Rate for a Specific Property
If you want to look up the tax rate for a specific address, here are the steps Bobby Mohebbi recommends.
Start with the county appraisal district website. For homes in Fort Bend County, visit the Fort Bend Central Appraisal District at fbcad.org. For Harris County, visit hcad.org. For Waller County, visit waller-cad.org. Enter the property address and you will find the appraised value, the list of taxing entities, and the tax rate for each entity.
Look for the MUD line item. On the appraisal district record, you will see every taxing entity listed with its own rate. If a MUD applies, it will appear as a separate line labeled with the district name and number.
Add up all the individual rates to get your total effective tax rate. This combined rate is what you multiply by your taxable value (after exemptions) to estimate your annual tax bill.
For new construction homes that have not yet been appraised, the builder's sales representative should be able to provide the estimated tax rate. However, Bobby Mohebbi independently verifies this number because builder estimates are sometimes based on the community average rather than the specific lot and section.
You can also use the Texas Commission on Environmental Quality's Water Districts Viewer to look up any MUD by location and see its boundaries, creation date, and linked information. This tool is helpful for verifying which MUD serves a specific address.
What Bobby Mohebbi Reviews for Every Buyer
Property taxes are not something Bobby Mohebbi leaves to guesswork. For every property a Mohebbi Realty Group buyer considers, the team reviews the total effective tax rate at the lot level, the specific MUD assignment and its current rate, the MUD's outstanding bond debt and rate history, any upcoming bond elections that could affect future rates, the applicable homestead exemptions and additional exemptions the buyer may qualify for, and the total estimated monthly tax escrow to ensure it aligns with the buyer's affordability target.
This level of detail matters because two homes at the same price in the same general area can have very different monthly costs depending on their tax structure. A $350,000 home in one MUD may cost $200 per month more than a $350,000 home two streets over in a different MUD. That difference compounds over years of ownership and directly affects your quality of life.
Frequently Asked Questions
What is a MUD tax in Katy, TX?
A MUD tax is a property tax levied by a Municipal Utility District to repay bonds that financed infrastructure such as water systems, sewer lines, drainage, and roads. It appears as a separate line item on your property tax bill, in addition to school district, county, and city taxes. MUD taxes are extremely common in newer master-planned communities throughout the Katy, Fulshear, Cypress, and Richmond area.
How much are property taxes in Katy, TX?
Total effective property tax rates in the Katy area range from approximately 2.3% to 3.6% depending on the specific location, school district, county, and MUD assignment. Established communities like Cinco Ranch and Seven Meadows tend to have lower rates (2.3% to 2.8%), while newer communities like Sunterra have higher rates (3.3% to 3.6%) due to higher outstanding MUD bond debt.
Do MUD taxes go down over time?
Yes, in most cases. MUD tax rates primarily pay off infrastructure bonds. As those bonds are retired over a 20 to 40-year period, the debt service portion of the rate decreases significantly. Some older MUD districts in the Houston area have seen their rates decline by 50% to 75% from their original levels. However, rates can increase if new bonds are issued or if property values decline.
What is the homestead exemption in Texas?
The Texas homestead exemption reduces the taxable value of your primary residence by $100,000 for school district taxes. Additional exemptions may be available from your county and MUD. You must file for the exemption with your county appraisal district after closing — it is not automatic. Filing is free and only needs to be done once.
Are MUD taxes and HOA dues the same thing?
No. MUD taxes are government property taxes that fund infrastructure and utilities. HOA dues are private fees that fund community maintenance, amenities, and landscaping. In most Katy-area master-planned communities, you will pay both. They serve different purposes and are billed separately.
How do I find out which MUD my home is in?
Check the property's record on the county appraisal district website (fbcad.org for Fort Bend County, hcad.org for Harris County, waller-cad.org for Waller County). The MUD will appear as a separate taxing entity with its own rate. You can also use the Texas Commission on Environmental Quality Water Districts Viewer to look up MUD boundaries by location. Bobby Mohebbi identifies the specific MUD for every property his buyers consider.
Can two homes in the same community have different tax rates?
Yes. Within a single master-planned community, different sections may be assigned to different MUD districts, each with its own tax rate. Some sections may also fall in different counties or different school districts. This is why Bobby Mohebbi reviews the tax rate at the specific lot level, not the community level.
