LLC?
S Corp?
DBA?
My wife has her business set up as a Sole Proprietor. Her income and tax deductions get added onto mine. We use it lower my W2 taxable income with write offs.
DBA...I did it for years.
Sole prop. For now. If it gets bigger deal with it later.
There is zero tax advantage for a LLC over a sole proprietorship. A Single Member LLC is a disregarded entity for IRS tax purposes & you would still file a Schedule C. The LLC is subject to self-employment tax, same as a Schedule C.
The S-Corp would help you bypass some of the self-employment tax, but you would need to do payroll, or hire a payroll company.
It depends on your Gross Income & Expenses and how much Profit you expect to make whether it is worthwhile to set up an entity. Also, how long do you plan on doing this? If only a for a year or two, then it might not be worth it.
