Kendall County Property Tax

Kendall County property tax comes in two numbers that are easy to confuse. The county's own adopted rate is $0.377000 per $100 of value for the 2025 tax year - and it is only the Kendall County government's portion. Your actual bill is the sum of every overlapping taxing unit that covers your parcel: your school district, your city (if any), the county, and a small countywide groundwater district. Combined, the typical total effective rate in Kendall County is about 1.10% of market value - an estimate from Census ACS 2024 5-year data (median real estate taxes paid $5,656 divided by median home value $512,700). Because the mix of taxing units differs from parcel to parcel, there is no single "Kendall County rate" for a full bill; the figures below are worked examples.

Kendall County's own rate of $0.377000 is modest, and the county keeps bills near the statewide norm because it has no countywide hospital district and no community college taxing district - two lines that inflate bills in many Texas counties. The only countywide add-on is the small Cow Creek Groundwater Conservation District ($0.005000). What drives Kendall County bills is high home values: this is a fast-growing, high-value San Antonio Hill Country market (Boerne and Fair Oaks Ranch), so even a modest rate produces a large dollar bill. One local wrinkle: newer subdivisions can add a municipal utility district (MUD) rate - Kendall County MUD #1 ($0.650000) or the Miralomas MUD ($1.000000) - on top of the base stack.

Rates from the Kendall Appraisal District 2025 adopted tax rates. This example is for a City of Boerne / Boerne ISD parcel; your total depends on your city and school district. The other school district is Comfort ISD ($0.932800). Unincorporated Boerne ISD parcels pay no city rate (about $1.392900 combined). Newer subdivisions may add Kendall County MUD #1 ($0.650000) or the Miralomas MUD ($1.000000).

Where your property-tax dollar goes

Boerne ISD ~54.2% City ~25.3% County ~20.2% Groundwater ~0.3%

On a typical City of Boerne / Boerne ISD parcel, Boerne ISD is about 54.2% of the nominal bill ($1.010900 / $1.8645 nominal total), the City of Boerne about 25.3%, Kendall County about 20.2%, and the Cow Creek Groundwater Conservation District about 0.3%. Percentages are rounded and use the nominal posted rates before any exemption - after the $140,000 school-district homestead exemption the taxable amount drops sharply, which is part of why the county's typical effective rate (about 1.10%) sits well below the nominal stacked rate (about 1.86%).

Who appraises, bills, and collects in Kendall County

Homestead exemption, the 10% cap, and key dates

If you own and occupy your home as your principal residence on January 1, you can claim a residence homestead exemption, and you generally apply through the Kendall Appraisal District. For a Boerne ISD parcel, the statewide school-district exemption removes $140,000 from the value the school district taxes for the 2025 tax year. If the owner is 65 or older, an additional $60,000 ISD exemption applies. Kendall County itself grants a $10,000 local homestead against the county's own portion.

Some Kendall County cities also grant local-option homestead exemptions, but the exact per-unit amounts vary and were not fully extracted in this pass. Because those interact with each unit's own value, the calculator below models only the statutory $140,000 school-district homestead and treats its output as the conservative (high) end - a real bill with the county's $10,000 homestead and any city exemptions is lower. Confirm the exact exemptions on your account with the Kendall Appraisal District.

Separately, the 10% homestead appraisal cap limits how much your homestead's appraised (taxed) value can rise to 10% per year, not counting new improvements. The cap applies to the appraised value used for your bill, not the market value the appraisal district sets, and it starts the year after you first qualify for the homestead exemption.

Key dates: payment is due January 31 and unpaid amounts become delinquent February 1. The statewide protest deadline is May 15 or 30 days after your appraisal notice is delivered, whichever is later. Texas Tax Code Section 1.06 rolls any deadline that falls on a weekend or holiday to the next business day. We were not able to extract a Kendall County-specific penalty-and-interest schedule from an official source in this pass, so no penalty percentages are stated on this page.

How to protest your appraisal

Protests go to the Kendall Appraisal District, which publishes its protest procedures and deadlines and runs the property search and appeals process. File and track everything at kendallad.org. Some private firms offer to handle protests for a percentage of any tax savings; such firms exist and charge a contingency fee, but we do not cite any savings figure or success rate as fact - results vary by parcel and year.

Vehicle Taxes in Texas

Unlike many states, Texas does not levy an annual value-based property tax on cars or other vehicles. There is no yearly "car tax" bill in Kendall County. Instead, vehicle taxes in Texas work two ways:

• One-time motor-vehicle sales/use tax of 6.25% at purchase. For a private-party sale, the tax is charged on the greater of the actual sales price or 80% of the vehicle's Standard Presumptive Value (SPV). A vehicle received as a gift is taxed at a flat $10 instead.
• A flat annual registration fee (plus any local add-ons), which is a fixed fee, not a tax on the vehicle's value. In Kendall County you register and title through the Kendall County Tax Assessor-Collector.

So if you searched for a Texas car or vehicle sales tax, the answer is the one-time 6.25% charged when the vehicle is titled - there is no recurring vehicle property tax to budget for each year.

Kendall County Sales Tax

The combined sales tax rate in the City of Boerne is 8.25% - the Texas maximum. It is made up of the 6.25% state rate, a 0.50% Kendall County rate, and a 1.50% city rate. Kendall County does levy its own 0.50% county sales tax, which applies countywide - so even outside a city the rate is 6.75%. Texas law caps the total local portion at 2.0%, so once the county's 0.50% and the city's 1.50% are combined, no further local rate can stack on top - which is why 8.25% is the maximum combined sales tax here.

City of Boerne (Kendall County) sales tax components

Component	Rate
Texas state rate	6.25%
Kendall County	0.50%
City of Boerne (local)	1.50%
Combined rate	8.25%

The 2.00% local share is the maximum Texas allows and here is split between the 0.50% county rate and the 1.50% city rate. Outside city limits the rate is 6.75% (state plus the countywide 0.50%). The exact city-versus-economic-development split of the Boerne local rate varies. Groceries and most unprepared food are exempt from sales tax.

Real Example: a $512,700 Boerne Home

Here is how the numbers flow on a representative $512,700 City of Boerne / Boerne ISD home (the county median value) with a homestead exemption (owner under 65), applying only the school-district homestead to the school unit:

• Market value: $512,700.
• Homestead exemption: the $140,000 school-district exemption drops the Boerne ISD taxable value to $372,700. The other units tax the full $512,700 in this simplified example.
• Stacked total: school $372,700 × 1.010900% = ~$3,768; city $512,700 × 0.471600% = ~$2,418; county $512,700 × 0.377000% = ~$1,933; groundwater $512,700 × 0.005000% = ~$26.
• Estimated annual bill: about $8,145 per year.
• Monthly equivalent: about $679 per month.
• Effective rate: about 1.59% of market value in this simplified example.

How this compares to the county-wide median. The Census ACS county-wide median bill is about $5,656 (roughly 1.10% effective). This Boerne city example lands above that, and that is expected: Boerne is an incorporated city carrying a full stack, while much of Kendall County is unincorporated Hill Country with no city rate, and over-65 owners have a school-tax ceiling that holds their bills down. A homesteaded parcel with no city rate (school + county + groundwater, roughly $5,727 on the same $512,700 value) would pay closer to 1.12%, very near the county median, and a real over-65 homestead - with the extra $60,000 school exemption and the county's $10,000 homestead - would be lower still. A non-homestead $512,700 Boerne parcel would pay closer to the full nominal ~1.86%, or about $9,558.

Limitations:

• Your total varies by school district and city; a Comfort ISD, unincorporated, or MUD parcel uses a different stack.
• Local-option city homestead exemptions, Kendall County's $10,000 homestead, and over-65, disability, and disabled-veteran exemptions are not modeled in the simplified example above; this example applies only the school-district homestead, so a real homesteaded bill is lower.
• Kendall County's exact penalty-and-interest schedule was not available from an official source in this pass and is not stated here.
• New-construction homes are often taxed on land only in the first year, then jump once the structure is on the roll.
• This is an estimate, not a parcel-exact bill. The typical effective rate is a Census ACS estimate, not a guaranteed rate.
