Independent Contractor:
Pros: Eat what you kill, more potential for higher income, good for hard workers who are self starters, more control over time off/work hours etc.
Cons: No income guarantee (sometimes you can get one for year 1), bad if you need to be told what to do, need to concentrate on expenses instead of just being a doctor, no predictability on paychecks
Salaried Employee:
Exactly the opposite
When I took my first job, I was salaried for 2 yrs then a IC for the next two (then I left that practice). When I was salaried, I made a decent living, but left 20% of my collections on the table over those 2 yrs. But I did not have to worry.
Once I was a contractor, my income increased significantly. But during that time, a local HMO went bancrupt in late November, and halted ALL physician payments. No one in our practice (except the employees) received a paycheck for the months of December and January, since we were upside down. Once the settlement happened, we got a HUGE paycheck, but that was like 6 months later. I had just bought a house, and luckily, my wifes income could cover the mortgage.
Personally, I prefer working for myself, and that is what I do now. But it is not for everybody. If you don't want to worry, and just show up, go to work, and get a paycheck. Then become salaried. It will be better for your mental well being.
