There is no state property tax in Texas. A Katy bill is the sum of the county, city, school district, community college, hospital district and any utility or improvement district rates that apply to the home, so two homes at the same price can carry different rates.

Property tax by price point in Katy
The 2.52% rate applied to the purchase price. Each figure is the first full-year bill before the homestead exemption.
| Purchase price | Annual tax | Monthly |
|---|---|---|
| $300,000 | $7,572 | $631 |
| $400,000 | $10,096 | $841 |
| $500,000 | $12,620 | $1,052 |
| $750,000 | $18,930 | $1,578 |
| $1,000,000 | $25,240 | $2,103 |
Most lenders collect property tax monthly with the mortgage payment, hold it in an escrow account and pay the county when the bill is due. The monthly column is roughly what tax adds to the payment on top of principal, interest and insurance, so on a $1,000,000 home in Katy plan on about $2,103 a month for tax alone.

How Katy compares with a year ago
| Measure | May to October 2025 | May to October 2026 |
|---|---|---|
| Closings | 3,542 | 2,937 |
| Median sale price | $343,525 | $349,000 (1.6%) |
| Tax on the median home | $9,431 | $8,809 |
| Rate | 2.75% | 2.52% |
The median sale price rose 1.6%. A buyer's bill follows the appraisal district's value, which moves toward the price paid, while an existing homestead's taxable value can rise at most 10% a year.
Why your bill will not match the listing
The appraisal district values every home at market each January 1, so the bill on a Katy listing reflects the seller's appraised value and exemptions, and it typically rises toward the purchase price the year after you buy. New construction is often taxed as a lot only in its first year.
The school district homestead exemption is $140,000, and the over-65 or disabled exemption adds $60,000. Once the exemption is in place, a homestead's taxable value can rise at most 10% a year. Filing is free with the county appraisal district by April 30. A buyer whose seller already had an exemption waits until the next year to file; a buyer whose seller had none can apply right away for the rest of the year (source: The Texas Tribune, October 20, 2026, read November 7, 2026).
Illustration: at a 1.0% school district rate, the $140,000 exemption is worth about $1,400 a year. Your district's rate will differ.
What is driving Katy's property taxes (local commentary)
Katy has the highest property tax rates of any city in this series: a 2.52% median, with the middle half of homes between 2.22% and 3.26%, 52% of homes at 2.5% or higher and 31% at 3.0% or higher. The driver is the age of the home, not its price: homes built in 2020 or later carry a 3.28% median rate ($11,184 on a $340,990 home) against 2.17% for homes built before 2000 ($7,221 on $332,750), because newer master-planned communities such as Cane Island (3.04%) and Ventana Lakes (2.79%) are financed through utility districts whose debt is repaid on the tax bill. Cinco Ranch (2.07%), Kelliwood (2.10%) and Memorial Parkway (2.10%) are the established sections where the rate settles near Houston's. The median rate fell from 2.75% to 2.52% year over year, the biggest move of any city in this series, while the median price rose 1.6%.
How to budget for property tax when buying in Katy
- Estimate from your price, not the listing. Multiply your purchase price by the rate on this page (2.52%); on a $1,000,000 home that is $25,240 a year.
- Divide by 12 and add it to the mortgage payment. Most lenders escrow property tax, so about $2,103 a month on that $1,000,000 home is part of the payment you qualify for.
- File the homestead exemption as soon as you are eligible. Filing is free with the county appraisal district by April 30.
- Check the prior owner's full bill on the county portal. Look for MUD or PID charges that sit outside the percentage rate.
- Compare two homes you like on tax, not just price. A district line can be worth over $1,000 a year.
Methodology
We looked at closings of single family homes, condos and townhouses in Katy from our MLS feed, closed May 1 through October 31, 2026 (2,937 closings), compared with May through October 2025 (3,542 closings). The rate is the total tax rate reported on each listing, and the tax is that rate applied to the sale price. Neighborhoods need at least 20 closings; figures are medians. Of the 2,937 closings, 2,680 had a tax rate on the listing; rates are medians of those homes, and every bill is shown before exemptions. The utility district comparison uses the municipal utility district (MUD) flag on the listing. Dollar figures on this page use the unrounded median rate (2.524%); the rate is shown rounded to two decimals. Published November 2026.
FAQ
How much is property tax in Katy?
About 2.52% of the home's value (median total tax rate on listings, all taxing units combined). On the $349,000 median home sold in Katy from May through October 2026, that is $8,809 a year, or $734 a month, before the homestead exemption.
Is a buyer's agent rebate worth it in Katy?
On a $349,000 home, the median sold in Katy from May through October 2026, the buyer-side commission is a much larger number than a year of property tax. TurboHome refunds most of it to the buyer at closing. Compare the companies that refund the buyer's agent commission.
Will my property tax be the same as the seller's?
No. The appraisal district moves the home's value toward your purchase price, usually the year after you buy, and your exemptions differ from the seller's. Budget from the rate on this page times your price, not the bill on the listing.
How much does the homestead exemption save in Katy?
The school district homestead exemption takes $140,000 off the home's taxable value, and the over-65 or disabled exemption adds $60,000. As an illustration, at a 1.0% school district rate the $140,000 exemption is worth about $1,400 a year. Filing is free with the county appraisal district by April 30.
Which Katy neighborhoods have the lowest property tax?
Among the 11 neighborhoods in our table, Memorial Parkway ($290,000 median, $6,090 a year) and Ventana Lakes ($318,000 median, $8,872 a year) have the smallest bills on the median home.
