Your notice of estimated taxes and the tax-rate website (DRAFT – not published)

In short

Each summer every taxing unit must post its proposed rate on a state-required website.¹ Owners must be sent a notice that their estimated taxes are there.² For Williamson County it is williamsonpropertytaxes.org.³ Look up your own home to see what each body plans to charge.

The 30-second version

• Where: Texas.gov/PropertyTaxes links to each county’s site.¹
• When: early August, after values are certified.²
• What: for each body, last year’s rate, the no-new-revenue rate, the voter-approval rate, and the proposed or adopted rate.¹
• Why it matters: it lists each body’s hearing date, so you know when to speak.¹

How to read your entry

Column	What it means
No-new-revenue rate	About the same money from the same homes as last year1
Voter-approval rate	Highest rate without an election1
Proposed / adopted rate	What the body plans or chose1
Estimated tax	Your value times each rate, after exemptions1

Example: the county adopted 0.381218 for 2026, a bit above its no-new-revenue rate of 0.376230. Its separate road rate went the other way: 0.040329, below its 0.045317. Added together, the two equal the combined no-new-revenue rate, 0.421547.³

The other side

• It is an estimate. Your final bill comes in October and may differ.²
• It is detailed, and owners have to go to the website to see it. The law also requires a newspaper notice of rate hearings.²

Questions to ask

• Where does the tax office post the dates of each unit’s rate hearing?
• How does the tax office update the tax-rate website when a unit changes its proposed rate?

What you can do next
