I have a job that I get paid X per day. It is not salaried nor am I connected to the business that owns the plane. They want to pay me X as an FO to sit in the right seat.
Now my question is: How does that work with Taxes? How do I show that i have $ coming in? My family needs a new car and I need to show that I bring in Y amount each month. How does that work? Is a business license required? Thanks in advance.
