The qualified business income (QBI) deduction is not a business deduction; it does not appear on Schedule C or any other business tax return. Instead, it is a personal deduction on Form 1040 that is subtracted after reducing adjusted gross income by the standard deduction or itemized deductions.
Certain employees, such as full-time life insurance salespersons, who may report income and deductions on Schedule C, rather than on Schedule A as miscellaneous itemized deductions.
