A small business doesn't need to be profitable on paper it just needs to cover the owners salary and expenses.
If you have write ons then you need write offs. The write offs are the key. If I can pay all my "expenses" then I really don't need a profit..
The goal is to hit zero on the taxable income line. For example, I'll drive a new truck every year or every other year before I write a check to the gov't. A F350 Platinum Tremor is an expense as I need transportation back and forth from the job sites.
Now I just need to make enough money to buy the truck...
