In the U.S., if you can produce one or more W-2 tax forms (annual report of wages paid) adding up to about a full-time job, the banks check it off their list and move on to the next item. However if you are self-employed, they want multiple year copies of your detail business income tax form, and letters from your accountant or tax preparer stating that your business is profitable, viable in the future, etc (which is just the banks trying to meaninglessly off-load some of their risk to a 3rd party).
