When you compare California tax you should then add the cost of private health insurance and retirement plan. I'd be be really surprised if the sum would come under 42%. It seems to me you're getting a very good deal! I would not have expected the 7% average income tax in particular, is it due to the sole proprietorship? Would you pay more if you directly invoiced as a person?
