Property Tax on Canyon Lake: The No-City-Tax Advantage

Why Canyon Lake's Tax Rate Is So Low

Canyon Lake has no incorporated city. The communities around the lake -- Canyon Lake Village, Canyon Lake Hills, Canyon Lake Forest, Sattler, Startzville, Canyon City, and Mystic Shores among them -- are all unincorporated census-designated places within Comal County. This means there is no city government, no city tax rate, no city services levy, and no city development authority to add to your bill. Property owners pay two taxing entities: Comal County and Comal Independent School District. That's it.

The result is an effective combined rate of approximately 0.83% -- roughly half the effective rate you pay on a comparable home in The Colony on Lewisville Lake (1.93%), less than half the rate in Eagle Mountain Lake's Tarrant County communities (2.4%), and dramatically lower than DFW metro lake properties generally. The Canyon Lake median effective rate of 0.83% is one of the lowest of any significant Texas lake market with more than 1,000 active listings.

The Numbers

These figures use the Comal County median effective rate. Your specific bill depends on your CAD-assessed value (which may differ from market value) and the exact taxing entities that apply to your parcel. Some subdivisions in the Canyon Lake area fall within specific Water Districts or Emergency Service Districts that can add small amounts to the total. The Canyon Ranch MUD and Johnson Ranch MUD cover portions of the Spring Branch area adjacent to Canyon Lake. Verify your specific parcel's taxing entities through the Comal Appraisal District before closing.

What the Tax Rate Includes

The two primary components of a Canyon Lake property tax bill:

• Comal County: The county rate was $0.264 per $100 in 2025, set by Comal County Commissioners Court in September 2024. Comal County has held one of the lowest county rates in Texas for several years, with commissioners maintaining a no-new-revenue approach during periods of rising property values. The 2026 budget was approved at a rate of $0.305 per $100 -- a 4-cent increase taking effect for tax year 2025-2026, the first meaningful increase in several years, reflecting significant county infrastructure needs driven by rapid regional growth.
• Comal ISD: The school district levy represents the largest single component of the bill. Comal ISD serves the entire Comal County area. The 2025-2026 homestead exemption increase (from $100,000 to $140,000 under Texas Proposition 13, approved by voters in November 2024) reduced school district bills for primary residences significantly. Comal ISD is a large, well-rated district serving 30,000+ students across 589 square miles.

The Texas Homestead Exemption at Canyon Lake

Primary residence owners can apply for the Texas homestead exemption through the Comal Appraisal District. As of 2025, following the approval of Proposition 13, the school district homestead exemption increased from $100,000 to $140,000 -- meaning the first $140,000 of your home's value is exempt from school district taxation. At Canyon Lake's school district levy rate, this exemption provides meaningful savings. On a $500,000 home, the exemption eliminates taxes on $140,000 of value. Apply through the Comal Appraisal District by April 30. You may file up to two years late if you miss the initial deadline.

For homeowners 65 and older, Texas provides an Over-65 exemption of an additional $10,000 on top of the standard exemption, plus the school district tax freeze. Once you turn 65 and qualify, your school district portion of the tax bill is capped at the amount you paid in the qualifying year, regardless of future value increases. On a lake where property values have appreciated significantly, this freeze is a substantial benefit for retirees on fixed incomes. Contact the Comal Appraisal District to apply as soon as you turn 65.

How Canyon Lake Compares to Other Texas Lake Markets

The no-city-tax advantage at Canyon Lake puts it in a different category from almost every other major Texas lake market:

• vs. Lewisville Lake (Denton County, LISD): Lewisville/LISD runs 1.7227%. On a $500,000 home, that is $8,614 per year versus Canyon Lake's ~$4,150 -- a difference of $4,464 per year. Over 10 years: $44,640.
• vs. Eagle Mountain Lake (Tarrant County): Tarrant County lake communities run ~2.4% effective rate. On $500,000 that is $12,000 per year versus $4,150 -- a gap of $7,850 per year.
• vs. Lake LBJ (Llano/Burnet County): Llano County effective rate is approximately 1.1%. On $500,000 that is $5,500 -- higher than Canyon Lake's $4,150 but much closer than DFW lakes.
• vs. Lake Granbury (Hood County): Hood County effective rate is approximately 1.60%. On $500,000 that is $8,000 per year versus $4,150.

The tax advantage at Canyon Lake is one of the lake's most tangible financial benefits, and it is structural -- it exists because there is no city government to add a levy, not because of a temporary rate cut or a partial exemption that could change. As long as Canyon Lake remains unincorporated, the no-city-tax advantage persists. There have been occasional discussions over the years about incorporation, but no serious movement toward creating a city of Canyon Lake has advanced through the political process.

The No State Income Tax Context

Like all Texas properties, Canyon Lake homes carry no state income tax liability. Social Security, pension distributions, IRA withdrawals, dividends, capital gains, and all other forms of income are exempt from state income tax in Texas. Combined with Canyon Lake's ~0.83% effective property tax rate, the total state and local tax burden for a Canyon Lake resident is exceptionally low by any national comparison. A retired couple with $150,000 in combined income who relocates from a high-income-tax state like California (up to 13.3% marginal rate) or Illinois (4.95% flat rate) saves substantial money in state income tax that more than offsets even a doubled property tax bill -- and at Canyon Lake, the property tax is already among the lowest available in Texas.
