What is a MUD in Texas?

A municipal utility district is a local government, created under the Texas Water Code, that builds and runs water, sewer and drainage (and sometimes parks and roads) for a neighborhood, usually outside or at the edge of a city. It pays for them by selling bonds and charging a property tax to the homes inside it.

Is a MUD tax forever?

No set end date applies to every MUD. The debt part of the rate falls as the district's bonds are paid off and its tax base grows, and a city can annex a MUD and take over its debt. Until then the district keeps levying the tax each year.

What is the difference between a MUD and a PID?

A MUD charges a tax rate on your home's value. A PID (public improvement district) charges an assessment set by a city or county, often a fixed yearly installment per lot that runs for a set number of years. Both appear on or alongside the property tax bill.

Does the seller have to tell me about a MUD or PID?

Yes. Texas Water Code section 49.452 requires a notice to buyers of land in a MUD or similar district, and Texas Property Code section 5.014 requires a notice of PID assessment obligations, both before the contract is signed.

MUD and PID taxes in Texas

Updated October 27, 2026

Many newer Texas neighborhoods were built with money borrowed by a special district. Homeowners repay it through an extra tax (a MUD) or an assessment (a PID). It is legal, common and disclosed, but it can add thousands of dollars a year, so know the number before you make an offer.

Municipal utility districts (MUDs)

A MUD is a small unit of local government created under the Texas Water Code. A developer usually asks for it so the district can sell tax-exempt bonds to pay for the water lines, sewer plant and drainage a new subdivision needs. The homeowners then elect a board and pay a property tax to the district.

The MUD rate is charged per $100 of your home's taxable value, on top of the county, city and school district rates.
It usually has two parts: a debt service rate that repays the bonds and a maintenance and operations rate.
The rate is set every year. It tends to fall as the district's bonds are repaid and more homes join the tax base, but it can rise.
If a city annexes the area, the city can take over the district and its debt.

Similar districts work the same way: water control and improvement districts (WCIDs), fresh water supply districts, utility districts, municipal management districts and road districts.

Public improvement districts (PIDs)

A PID is created by a city or county under chapter 372 of the Local Government Code. Instead of a tax rate, owners pay an assessment: often a fixed yearly installment per lot for a set number of years (for example 20 to 30), which can be paid off early. The installment is commonly billed with the property taxes, so it is easy to miss on a listing that shows only the "tax rate".

The notices sellers must give

MUD and water districts: Texas Water Code section 49.452 requires the seller to give a notice stating the district's tax rate and its bonds before the contract is signed. The notice is often an addendum to the sales contract.
PIDs: Texas Property Code section 5.014 requires a notice of the PID assessment obligations before the contract is signed.

What to ask before you buy

What was the total tax rate last year, including every district? What were the actual taxes paid?
Is there a PID assessment? What is the yearly installment, how many years remain, and what is the payoff amount?
How much debt does the MUD still owe, and has it authorized more bonds it hasn't sold yet?
Has the city said it will annex the district?

HouseDirt finds the districts that overlap the exact lot, their rates from the Texas Comptroller, the MUD's outstanding debt where the state publishes it, and PID installments where the district's administrator publishes its roll.
