Driving the truck as contract labor,you need a contract from the people your going to drive for.
If they give you a w4 to fill out,then they are going to withhold your taxes and your actually a company driver for them
In any event,you can right off 80% of $52 per day for every day your away from home.Unless the company your driving for pays you extra for a food allowance.
Other right offs,are almost all the money you spend to do your job,from doing your laundry on the road,to motels,even the pens you buy can be a right off.
You dont need a specialized accountant,but you do need one that is familiar with the trucking tax laws.H and R Block isn't a good place for truckers to go.
Good luck,welcome to E O
also,try with holding 30% of your pay for you tax liability,this should more than cover your taxes
