Katy is one of the few Houston-area communities where two homes that look nearly identical, sit a few minutes apart, and share a mailing address can carry meaningfully different annual costs. The reason is not the houses. It is the county line — and the district lines layered on top of it.
Greater Katy spans portions of Harris County, Fort Bend County, and Waller County. Each has its own county rate. Layer on the relevant school district, city or municipal utility district (MUD), emergency services district, and any special districts tied to a master-planned community, and you end up with a combined rate that can vary noticeably from one subdivision to the next.
Where the differences come from
The biggest swing factor in newer Katy-area neighborhoods is usually the MUD. Master-planned communities across the region commonly carry additional district taxes on top of standard county, city, and school rates, and those rates are tied to the infrastructure debt the district issued to build roads, water, drainage, and amenities. Newer districts that are still paying down that debt typically carry higher rates than older, more established ones whose bonds are further along.
This is not a knock on new construction. That MUD is what funded the trails, the detention ponds, and the water system. But it is a real line item, and it belongs in your monthly budget from day one — not as a surprise when the escrow analysis arrives.
What changed for 2026
Texas homeowners have seen the school district homestead exemption increase in recent years, with the taxable value reduction for a primary residence rising again for 2026. Fort Bend County also offers an additional county homestead exemption on top of the state-level relief. The practical effect: your exemption picture matters more than it used to, and the gap between an exempted primary residence and a non-exempt property has widened.
If you bought in the last year, confirm your homestead exemption is actually filed and applied. It is one of the highest-return 20 minutes a Texas homeowner can spend.
Three things to verify before you write an offer
- Pull the actual tax rate for that specific parcel, not the neighborhood average. The appraisal district record lists every taxing entity attached to the property.
- Ask what the seller’s current bill reflects. If they have a homestead or over-65 exemption and you will not qualify for the same one, your bill will not match theirs.
- Run the payment with taxes and insurance included. In this market, escrow is often the difference between two homes that appear equally affordable on list price alone.
None of this should scare you off a neighborhood. It should just be on the table before you fall in love with a floor plan.
We run these numbers address by address for Katy buyers every week, and we are happy to do it for a home you are considering — before you are under contract, when it still changes your decision.
