Hi Charlene, Good question. It shows you are thinking with a business head. PA means Professional Association and means that you have filed for Sub S Corporation status. I am not an attorney or CPA. When I became a PA I did so on the advice of my CPA.That advice was that if you are making over $50,000 annually you should consider this status. There is a tax benefit. Everyone's situation is different. So I advise you check with an accountant. If you are short on cash, H&R Block is pretty reasonable to start out. Check with your broker on who they use. Every agent needs a good tax advisor. By the way. Are you working yet? I am looking for an agent. Click on my info and send me an email.
