As a FIREd, long timer builder, I have seen this happen all too often, and strongly recommend that you avoid this mess. First, depending on the state and local tax burdens, you will be losing no less than 45% of your check to local, state, and federal taxes, plus social security (which is roughly 15% since you pay the employee and employer portions), medicare, unemployment, and more. Second, believe it or not, it's flat out illegal to do what you're being offered. The IRS has a very specific set of laws regarding who is, and isn't an employee. Basically, if you show up at your family's business every day, and receive direct supervision as to where to go, and what to do, you are an employee. If you use their tools to get the job done, you are an employee. OTOH, If you own a floor covering installation business, have a presence in the community as such, and are know as a contractor who works for all who seek your services, you are a contractor. The giant red flag here is that you are proposing to do the work of a subcontractor, who traditionally is paid unit rates (by the yard of sheet goods, sq. ft of hardwood installed, etc...) while being paid an hourly rate as a "subcontractor". Now, if you make a good faith attempt to pay your taxes in this case, you are viewed as the victim here. The IRS can, and has, inflicted a great deal of pain on those that do abuse employees in this manner. I have had two of my contractors (insulation and sheetrock subs) go through tremendous pain battling the IRS after the received notices that they owed hundreds of thousands in unpaid taxes and fines for illegally classifying employees. Finally, as another poster stated, at $20/hr once you pay your legitimate taxes and your own health insurance, you WILL be earning less than minimum wage. Also, in the event of a serious injury on the job, your brother will not only be paying the bills out of pocket, but in most states he will be paying huge fines for not having proper workman's comp. coverage on his employee. Your brother's proposal is common, and it may never come back to bite either of you in the ass, but if it does, it can get extraordinarily ugly.
