Property Taxes, MUD, and PID: The Line Items That Change Your Payment

The short answer
Two houses at the same purchase price can carry monthly payments $300 to $400 apart. The difference is the effective tax rate and whether the neighborhood carries a municipal utility district (MUD) or public improvement district (PID) assessment. Here is how to read both before you make an offer.
Property tax rates across Central Texas
Property tax in Texas combines county, city, school district, and any special district rates. In Travis County cities, effective rates have typically run 1.8% to 2.2%. In Williamson County (Round Rock, Georgetown, Leander), rates run similarly. In Hays County (Kyle, Buda, Wimberley), rates have reached 2.2% to 2.6% in some jurisdictions. On a $400,000 house, the difference between 1.8% and 2.5% is $2,800 per year — roughly $233 per month on your payment.
What a MUD is and why it matters
A Municipal Utility District is a special-purpose taxing district created to finance the infrastructure of a new development: roads, water, sewer, and drainage. The developer borrowed money backed by bonds, and property owners in the district repay those bonds through a supplemental MUD tax on top of county, city, and school taxes. MUD rates range from 0.2% to over 1.0% and typically decline over 20 to 30 years as the bonds are paid off.
Before you make an offer in a new development or a neighborhood built in the last 15 years, ask for the MUD rate. Add it to the county + city + school rate to get the effective total rate. Then calculate annual taxes against the purchase price and divide by 12. That number is your actual monthly tax burden — not what the listing shows.
What a PID is
A Public Improvement District is similar but levied differently. PIDs are typically used for amenity development: parks, trails, street lighting, neighborhood improvements. The assessment often appears as an annual flat amount on your property tax statement rather than a rate-based tax. On a $400,000 property in a PID zone, a $2,400/year assessment adds $200/month to your effective carrying cost.
How to find this information before you make an offer
- Ask the listing agent directly — they are required to disclose special assessments
- Look up the property on the county appraisal district website (Travis CAD, Williamson CAD, Hays CAD)
- Request the HOA and special district verification letter through title during the option period
- Check the Texas Comptroller's property tax database for historical tax rates by district
I pull tax history on every property I show clients because the listing's tax line often reflects the previous owner's homestead exemption, which resets at sale. New buyer, fresh calculation. In a MUD or PID zone, the difference between what the seller paid and what you'll pay can be significant. Run the number fresh every time.
