I live in Texas and have bought lots of trucks and trailers from out of state. You will only pay tax in the state where you register the trailer. I have bought several vehicles in Iowa, and never pay tax there. Bring it home, and you will be taxed when you get ready to register and put license on it. You can buy a "one trip" paper tag before you go, and use it to be legal towing back to Texas. That tag used to cost about $10.00. Not sure of cost now. When you get it home, you will need a safety inspection before you go get it registered.
