Please be careful about "our small business." A small business owned by two or more people (even spouses) is handled differently from a small business owned by one person.
If the business is not an LLC, and both spouses materially participate in business activities, then you can either
a. make one spouse the owner, file one schedule C, and make the other spouse an employee or subcontractor
b. or file two schedule Cs, each listing each spouse's share of the income and expenses.
If the business is an LLC, and the two spouses own the LLC, then
a. if you live in a community property state, you file two schedule Cs, each listing exactly half the income and expenses,
b. if you don't live in a community property state, you file a separate form 1065 partnership return. The partnership return generates a K-1 statement for each partner that goes on their personal form 1040.
