Texas does not have a state income tax, so they have to get their money other ways. Property tax is higher than some other states, but I doubt it is higher than California.
My house in town has a tax valuation of $135K and I pay somewhere around $2500 a year in property tax. My part of our family ranch is 60 acres and it only costs me $150 in taxes because there is little improvements on it right now. As soon as I build a house out there my taxes will jump to $1500-$2000 a year. If you have more than 6 acres you can claim an "Ag exemption" if you are using the land for agriculture which helps keep the taxes down. It also allows you to purchase anything agriculture, including dog food, sales tax free. All of my tractor parts, pick up parts, supplies for the ranch, and dog food is sales tax free for me.
Property taxes in Texas are the seventh highest — higher than California and New York at 1.62 percent on average, cali on avg is .72
