If you are self-employed you are a business and your should run your business like any other business type.
I incorporated because that is what was best for my business and me personally.
I have hired people and I have terminated people. Haven’t had a need to directly hire other notaries yet.
I enjoy the legal separation of entities due to incorporating. I do not enjoy the corporate and other taxes paid even though those were considered when making the decision to incorporate. And I like not having my business credit tied to my personal.
I miss the lax manor of accounting I could follow before incorporating and the ease of lots of other things that work for sole proprietorship but would cause a pit to open under your office if done with a corporation.
Each has their plus and minus factors. It’s simply about what you need as a business owner.
