It depends. Schedule C is for reporting the income and expense of the business. If this self-employment business is his alone, then regardless of if you funded the business, only he will report the income or loss.
Please note that if you live in a Community Property State (Arizona, California, Idaho, Louisiana, Nevada, New
Mexico, Texas, Washington, or Wisconsin), you may need to include some of his income on your return but you will not include that income on a Schedule C (instead, you will have an adjusting entry on line 21).
