Property Tax on Lewisville Lake: City-by-City Breakdown

How Texas Property Tax Works on Lewisville Lake

Texas has no state income tax and no state property tax. Your tax bill is assembled from multiple local taxing entities: Denton County (or Dallas County for the small southeastern portion of the lake), your city government, your school district, and in some areas a Municipal Utility District (MUD) or Special District overlay. Every Lewisville Lake property sits within a specific combination of these entities, and the total effective rate is what matters for your budget -- not the county rate alone.

The good news relative to most Texas metro areas: the Lewisville Lake shore communities in Denton County generally run lower effective rates than the Dallas County lakefront markets like Lake Ray Hubbard. The challenge is that the rate varies significantly depending on exactly which city your property sits in and which school district serves it -- and those boundaries do not always align with which shore of the lake you're looking at.

Effective Rate by City (2025 Tax Year)

The following effective rates represent the combined Denton County base rate, city rate, school district rate, and typical MUD overlays for properties in each community. Your specific parcel may differ depending on the exact taxing entities that apply to it -- always verify with the Denton Central Appraisal District (DCAD) for any property you are under contract on.

The spread across these communities is significant -- from 1.6523% in Hickory Creek (Lake Dallas ISD) to 2.0411% in The Colony (Little Elm ISD). On a $600,000 home, that gap is $2,333 per year. On a $1 million waterfront property, the same rate spread produces a difference of $3,888 per year -- nearly $39,000 over a ten-year horizon before factoring in value growth. Rates are sourced from the 2025 Old Republic Title DFW Property Tax Rate Guide (Denton Central Appraisal District source, December 2025). Verify your specific parcel's taxing entities through DCAD before closing.

The School District Factor

School district levies are the largest single component of your property tax bill -- typically representing 45% to 55% of the total combined rate. The Lewisville Lake shore spans four school districts:

• Lewisville ISD (LISD): Serves Lewisville, Highland Village, Flower Mound, and most of The Colony. 2025 ISD levy: $1.1178 per $100. LISD does NOT serve Hickory Creek -- a common buyer misconception. Strong academic performance, established facilities, Marcus High School.
• Lake Dallas ISD: Serves Lake Dallas, Hickory Creek, and portions of Shady Shores and Corinth. 2025 ISD levy: $1.2552 per $100 -- higher than LISD. Hickory Creek's overall rate (1.6523%) appears low because its city levy (0.2112) is the lowest on the lake. The school district levy itself is actually higher than LISD.
• Little Elm ISD (LEISD): Serves Little Elm and Oak Point, plus portions of The Colony in newer developments (where the rate jumps to 2.0411%). 2025 ISD levy: $1.2252 per $100. Always verify which ISD serves a specific Colony address before assuming the 1.9337% rate applies.
• Denton ISD: Serves parts of Little Elm, Shady Shores, Corinth, and Oak Point. 2025 ISD levy: $1.2069 per $100. Voters approved a 5-cent M&O increase in November 2025, generating approximately $26 million annually for teacher salaries, safety, and programs.

MUD Overlays and Special Districts

Municipal Utility Districts are common in rapidly developing areas of North Texas, and several Lewisville Lake communities -- particularly in Little Elm and newer sections of The Colony -- include MUD overlays that add 10 to 30 basis points to the effective rate on top of the city and school district rates. MUD levies typically fund the infrastructure debt for water, sewer, and road improvements in newer developments. They decline over time as the debt is retired, but during the paydown period they are a real cost that buyers in affected subdivisions must account for.

If you are under contract on a newer property in Little Elm or Oak Point particularly, ask your title company to pull the full taxing entity schedule for that parcel before closing. The difference between a MUD-encumbered property and a non-MUD property in the same city can be 20 to 30 basis points -- roughly $1,200 to $1,800 per year on a $600,000 home.

The Texas Homestead Exemption

Texas offers a meaningful homestead exemption for primary residences. Every Texas homeowner who uses the property as their principal residence can apply for the $100,000 school district homestead exemption, which removes $100,000 from the taxable value for school district purposes only. At a typical LISD rate, that exemption saves approximately $1,120 per year on your school district taxes alone. You must apply through the Denton Central Appraisal District by April 30 of the tax year, and you can file up to two years late if you miss the deadline.

For buyers 65 and older, Texas also provides an Over-65 exemption of an additional $10,000 on school district taxable value, plus a property tax freeze -- once you turn 65 and apply, your school district taxes are capped at the amount you paid in the year you qualified, regardless of how much your value increases after that. This freeze does not apply to city or county taxes, but the school district component is the largest single piece of your bill, so the freeze is a significant benefit for retirees on Lewisville Lake.

What the No State Income Tax Reality Means

Texas has no state income tax on earned income, retirement income, Social Security, or capital gains. For buyers relocating from Illinois (4.95%), California (up to 13.3%), New York (up to 10.9%), or other high-income-tax states, the savings can easily offset the property tax differential between Texas and lower-rate states. A household with $200,000 in combined income relocating from Illinois to a Lewisville Lake home would save approximately $9,900 per year in state income tax -- more than enough to cover a $10,000 annual property tax bill with room to spare.

The relevant comparison is total state and local tax burden, not just property tax rate in isolation. By that measure, Texas lakefront property is genuinely competitive with lake markets in income-tax states, even with effective rates above 1.7%.
