I think what he meant was that you have to consider a hefty tax burden come April 15 because, as a contractor, you don't get taxes taken out of your paycheck. This is where having a good accountant and knowing what expenses you can deduct comes in (to reduce your taxable income).

If for nothing else, you should have a business just so you can claim more expenses and reduce the amount you have to pay Uncle Sam (from my understanding, all you need to have is a profit motive -- not necessarily profits).
