The IRS form on which these deductions must be reported will depend on your form of business operation, that is, whether you're a sole proprietorship, partnership, LLC or corporation.

If you operate your business as a sole proprietorship, you will report business deductions on Schedule C of Form 1040. (You can use the simpler Schedule C-EZ if your business expenses are under $2,500, you do not have inventory or employees, you use the cash method of accounting, and certain other requirements are met.) If you do business as a partnership, you'll file Form 1065. If you operate as a corporation, you'll file Form 1120-A, Form 1120, or Form 1120-S for S corporations.
