How Much You Save on Property Taxes in Waller County

Texas has no state income tax, so the property tax bill is where living costs are really decided — and it is set street by street, not state-wide. Every home pays a stack of rates: the county, the school district, and any special district the address sits in. Cross a county line and the whole stack changes, which is why two similar homes twenty minutes apart can carry very different bills.

Sofi Lakes sits on the Waller County side of the Katy area, zoned to Royal ISD, with community infrastructure funded through a PID — not a MUD. The combined rate for a Sofi Lakes address is 3.68% of assessed value, everything included. Much of Katy proper sits in Harris County under Katy ISD, typically with a MUD on top.

If the home is your primary residence, the Texas homestead exemption removes $100,000 of value from the school-district portion before the rate applies — you file once with the appraisal district after moving in, and it keeps working every year.
