I'm a sole proprietor and have a big contract with a company. I want to pull in a fellow contractor (let's call them R) onto this project, and I have the option to either contract (1099) to them myself, or have them sign their own contract with the large company. I'd rather contract to them myself but I was wondering if this leads to more taxes. Would I be able to write off all payments to R as business expenses? and would my personal taxes still go up, since my sole proprietorship GROSS income went up?
