Property Tax Rates for Investment Properties in Williamson County
If you’re buying in Round Rock TX 2026, the tax bill is a major part of your math. Williamson County has always been distinct from Travis County, and 2026 is no exception.
Breaking Down the 2026 Rates
The Round Rock City Council adopted a property tax rate of 37.2 cents per $100 of valuation for the 2026 fiscal year. This reflects a slight increase to fund public safety and voter-approved bonds. When you add in the Williamson County general fund rate of approximately 0.413776, your total rate will vary slightly based on your specific school district and municipal utility district (MUD).
Why the Central Authority Matters
Navigating these numbers requires a 23-year veteran real estate agent. I make sure my clients understand that while the tax rate is slightly higher than the "no new revenue" rate, it supports the very infrastructure that keeps home values in Round Rock TX high. My 45 Google 5-star reviews often mention how I save buyers from "tax surprises" at closing.
