I am exploring creating a stump grinding business that I can sub-contract stumps to. I am currently a LLC and wonder if there are significant tax and insurance benefits to having a stump grinding biz that is separate. That would save a lot of time on my tree crew and subsequently save on Workers Comp. I assume the money the sub-contract work could also reflect a cost to my tree biz. Any other potential benefits? Can I do this without breaking the law? Concerns?
