Self-employment
Individuals who are self-employed can meet this requirement by providing business records and a copy of Internal Revenue Services (IRS) forms completed and filed, e.g. IRS Schedule SE or IRS Form 1040, Schedule C or Schedule F, showing entries for net earnings or losses. If the person hasn't been in business long enough to file a tax return, detailed records, such as a combination of ledger sheets, receipt books, self-employment worksheets for tracking potential tax liability must be provided. A business license does not in and of itself provide evidence of self-employment.
