The reason I don't pay taxes is everything is in cash.
My family owns a heating and air business, and we gross around 500k a year.
I can go out and do service calls, when they ask who to make the check out to I usually just say my name or the businesses name, and get my parents to just give me cash when I give them the checks.
I get 65 dollars for a service call...JUST for going to the house, wheter I do anything or not if I have to get the toolbag out and touch your unit its 65 dollars.
We have a decent markup on parts and also get 50 dollars per hour labor if it takes longer then an hour.
I can do average around 10 service calls per day and work basically when I want.
I do have a couple of degrees, business administration (Which is basically a joke) and computer programming. Neither of which paid anywhere near the heating and air industry.
Right now we have 10 units to change out, at 7k a piece (profit is about 3.5k per unit) and we will be able to get done with all 10 in around 10 days + service calls after we get done with those change outs.
Its physical labor but its not horrible.
And the 100k is revenue, still probobly 30k or so profits
