CPA wanted $3,500 to set up an LLC and turn it into an S-corp + the filing for the year. Said we could deduct 80% of my car and some knick knack stuff. Ran the math, came out to be breakeven. Get $3,500 back to spend $3,500, risk an audit, lots of headache, not worth it to me.
Probably the best reason for an LLC in your case is to split up your finances and protect your personal property (house/cash/other assets) in case your business gets sued. I don't think the tax advantages are huge but the potential losses difference if sued can certainly be huge if you don't separate your assets. I'd be surprised if your accountant didn't bring that up though.
