"The deduction is generally equal to the lesser of 20% of the taxpayer’s QBI plus 20% of the taxpayer’s qualified REIT dividends and qualified PTP income, or 20% of taxable income minus net capital gains. Deductions for taxpayers with taxable incomes above certain threshold amounts (which are adjusted annually for inflation) may be limited."
