Confused by the extra line items you are seeing on Georgetown property tax estimates? You are not alone. Many new and growing neighborhoods in Williamson County use special districts to fund infrastructure and amenities, which can change your monthly payment more than you expect. In this guide, you will learn what MUDs and PIDs are, how they differ, how they affect affordability and resale, and the exact steps to verify costs on any home you are considering. Let’s dive in.
What is a MUD?
A Municipal Utility District, or MUD, is a special-purpose local government that provides utility infrastructure for a defined area. In Texas, MUDs are created under state law to build and operate systems like water, wastewater, and drainage. Some MUDs also fund roads and parks.
MUDs finance projects by issuing bonds and then repaying those bonds with ad valorem property taxes that apply to all taxable property within the district. The district is governed by a board of directors, typically elected by residents or landowners. MUD taxes show up on your annual property tax bill as a separate taxing entity.
What is a PID?
A Public Improvement District, or PID, is created by a city or county to fund public improvements and services within a specific area. Instead of charging a general property tax, a PID levies special assessments on the properties that benefit from the improvements.
PID assessments can secure bonds and are often billed annually, sometimes as a separate line on your property tax statement. PIDs are administered by the city that created them, sometimes with help from an advisory board, and the city retains final oversight.
Key differences that affect your budget
How you are charged
- MUDs use ad valorem property taxes. These are based on your property’s taxable value and appear alongside other taxing units on your bill.
- PIDs use special assessments. These are benefit based, not value based, and often show up as their own line item. They may be fixed amounts or tied to the district’s bond debt service schedule.
Who controls decisions
- MUDs are governed by an elected board that sets budgets, manages contracts, and runs or oversees utility services for the district.
- PIDs are created and overseen by the city. The city council approves the PID service plan, assessments, and changes over time.
What gets funded
- MUDs typically fund core infrastructure like water, sewer, and drainage. Some also handle roads, parks, and basic public improvements.
- PIDs often fund enhancements such as streetscapes, lighting, landscaping, sidewalks, parks, and other improvements defined in the PID’s creation documents and service plan.
How long charges last
- MUDs continue until they are legally dissolved. Their taxes can decrease after bonds are repaid, but timing and amounts vary by district.
- PIDs usually run assessments for a set period tied to bond repayment. Once obligations are met, the PID may be wound down.
Mortgage and underwriting
Both MUD taxes and PID assessments are considered ongoing obligations tied to the property. Lenders include them in escrow and debt calculations. Some lenders may require a PID assessment payoff or special escrow handling, so it is smart to ask your lender early.
Real-world impact for Georgetown buyers
Ongoing cost
Expect an additional annual payment obligation. In a MUD, that is an ad valorem tax. In a PID, it is a special assessment. These amounts can be significant in newer communities where bonds funded initial infrastructure.
Rate changes over time
MUD tax rates are often higher in the early years after bonds are issued. Rates can decline as debt is paid, but there is no guaranteed timeline. PID assessments often follow a set schedule that runs until the bonds are paid off, though terms vary by district.
Affordability and qualification
Because lenders include MUD taxes or PID assessments in your monthly estimate, a high district cost can affect how much you qualify to borrow. Get accurate numbers before you write an offer so you can compare homes on a true apples-to-apples basis.
Exemptions
Homestead and other exemptions generally reduce ad valorem taxes, which can include the MUD portion. Special assessments from a PID are usually not reduced by homestead exemptions. If you plan to claim exemptions, confirm treatment with the Williamson County Appraisal District and the district or city staff.
How to confirm a property is in a MUD or PID
Use these local resources to verify details for any Georgetown address:
- Williamson County Appraisal District (WCAD): Look up the parcel to see listed taxing entities and whether a MUD is shown. WCAD maps can also help confirm district boundaries.
- Williamson County Tax Office: Review the current tax bill, payment history, and how any special assessments are billed.
- City of Georgetown: Check with planning, development services, or finance for PID creation ordinances, the PID service plan, and assessment methodology.
- District manager or MUD board: Request the current MUD budget, tax rate history, and outstanding bond information.
- Title company: Ask your closer to confirm special district notices, prorations, and any payoff or escrow requirements.
- Your lender: Confirm how they treat PID assessments and whether escrow or payoff will be required.

Resale considerations in Williamson County
District costs can influence buyer demand and pricing. Some buyers value newer infrastructure or enhanced neighborhood features and accept higher ongoing charges. Others prefer lower monthly costs. If you plan to resell, keep copies of district documents and track changes to the tax rate or assessment schedule. Clear documentation helps future buyers understand the value they are getting and the long-term cost.
