Have for years. What is funny is the things you are supposed to charge tax for and what is not taxable. Like if you cut limbs off a tree that is not taxable but if you haul them off then that is taxable. If yo build a retaining wall for water erosion than that is not taxable but if you build a retaining wall for looks than that is taxable, ect.....
Another thing you may not know is if get your Texas Sales and use Permit and buy plants wholesale, or even retail, and deliver and plant them you are supposed to have a Texas Nursery and Floral Permit.
