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.
For calendar year 2007, taxpayers covered by an HDHP may contribute up to the lesser of the annual deductible or $2,850 ($5,650 for family coverage).
