LLCs and S-Corps (or an LLC treated like an S-Corp) both will limit your liability to the assets of the business entity.
Both have different, but beneficial tax treatments of certain business expenses and programs vs. an SP.
Firstly, is you can hire employees, which can be your family members. This allows them to be covered by Health insurance (you can get group rates for as little as 2 people), but more importantly, your employee premium cost is a business expense (pre-tax dollars) vs. after-tax out of pocket expense - but only in the case of an LLC treated as an LLC or non-shareholders of an S-Corp. Plus, you can set up an HRA or HSA with your plan that puts more of the cost on a pre-tax dollars basis.
Same is true for retirement plans. An SEP IRA allows you to contribute up to 25% of an employees comp as a business expense - untaxable to the employee until they take withdrawls. Of course, you have to offer this to ALL qualifying employees, but if they are all family members for now, this is just another way to transfer the earnings of the biz to your family and minimize taxes. Or you can set up a 401K for your biz and every employee can contribute up to $15K per year in pre tax $. Add the company match of 4% of comp and you end up with about $16K tax free in your 401K. This is especially wonderful if your spouse has other employment. You spend that income, but 100% of what you pay out of your massage biz goes into the 401K.
You can also purchase a company SUV. (there is a min. weight limit of which most SUVs comply, this was aimed at spurring investment in delivery and harvesting equip) So long as you title it and pay for it with company funds, you can write off the expense in one year vs. depreciating over the life of the vehicle. In effect, the SUV costs 1/3 less due to the tax shield of the 1 year depreciation.
Same is true for your massage equipment, if the stimulus package passes. To spur investment, the tax code will let you write off the expense in one year instead of over the life - usually 5 years for most massage equip. But not for SPs, only for LLC or S Corp.
Of course, taking advaneforum.xxxe of any of this will have you barred from the Democratic party as these are precisely the types of "tax breaks for the rich and big business" both candidates are pledging to eliminate. Plus, since income from an S-Corp "flows through to the shareholders", any profit will be taxed at personal marginal tax rates, which are scheduled to go up in 2010 unless the tax cuts are made permanent. Don't forget the Alternative Minimum Tax - which has never been adjusted for inflation since it came into being nearly 30 years ago as a way to prvent the rich from avoiding taxes, kicks in at incomes starting around $50,000.
Congratulations, you are now considered "rich" by the political establishment and are fair game to be taxed into oblivion!
