This can help protect your personal life from your business as a realtor.
You will be able to collect your commission the only thing is you will need to register you name PA with the Department of Business Regulation or whoever issues your real estate license in your state so that your broker will be able to pay your commission to the business name.
LLC might not work as only brokers can register an LLC.
Before I became a Broker and opened my own firm I was a PA.
However, before you incorporate I suggest you speak with an account so you can register the corporation in away that you will benefit tax time. My suggestion is as an 1120 S corp so you can carry your business loss or income into your personal taxes and this way you will not be doubled taxed.
At some point you WILL be acquiring real estate creating greater need for this shield.
If your future involves working closely with investor types, simultaneous closing, assignments, commercial, funding, instruments of debt, mobile home parks, multifamily, complexes, ,you may find this an essential provision.
Then your accountant will direct you regarding your process.
If however your dream to fame and fortune only includes assisting others buy and sell real estate, the need for such protection is diminished, not eliminated.
Only "Brokers" can opt-in to receive their commissions through an LLC. So most can not. Don't know how it works in other states though.
