Property taxes in Flower Mound, TX

By Mariela Lovo Ol, REALTOR® · Updated

Property taxes in Flower Mound, TX combine a town rate, a county rate and a school district rate, plus any special district. Texas has no state property tax and no personal income tax. Here is how a Flower Mound bill is built and how exemptions lower it.

Which taxing units appear on a Flower Mound tax bill?

A typical bill includes the Town of Flower Mound, Denton County and a school district. The Town's rate is $0.387277 per $100 of value, and its proposed FY 2026-27 rate is the same. Denton County adopted $0.183394 for 2026-27.

School rates depend on the district. For 2026-27, Lewisville ISD adopted $1.0778 per $100 and Argyle ISD adopted $1.1558. A few areas are in Tarrant County, where the Tarrant Appraisal District values the home.

What exemptions can Flower Mound owners claim?

The Town's homestead exemption is the greater of $5,000 or 20% of value, effective on 2025 tax bills. Owners 65 and older receive a $150,000 Town exemption, in place since 2023.

School districts must exempt $140,000 of a homestead's value, plus $60,000 more for owners 65 or older or disabled. Denton CAD accepts homestead applications online; file once the home is your principal residence.

How does the 10% homestead cap work?

After you qualify for a homestead exemption, the appraised value used for taxes generally cannot rise more than 10% a year, plus new improvements. The cap starts the year after you first qualify. Values are set as of January 1, and bills are generally due by January 31 of the next year.

How do you protest your appraised value?

The deadline is May 15 or 30 days from the mailing date of your notice, whichever is later. Denton CAD accepts protests online, by mail or in person. Bring sales of similar homes and photos of any condition problems.

How do PIDs and MUDs change the bill?

River Walk at Central Park has its own Public Improvement District, created by a 2013 vote. If you buy there, ask how the assessment is billed and for how many years.

For any MUD or similar water district, Texas law requires the seller to give written notice of its tax rate before you sign. Canyon Falls buyers should also ask about HOA dues and any special district assessments.

How do you estimate your total payment?

Add the Town, county and school rates for your exact address, apply your exemptions, then add any PID and HOA dues. Plug the result into the mortgage calculator, and compare it with the full cost of living in Flower Mound.
