2017年的The Tax Cuts and Jobs Act/減稅就業法案頒布了Internal Revenue Code Section 199A，規定對符合條件的flow-through entities可扣除高達20%的商業收入。

The qualified business income QBI deduction適用于除了C corporation以外的所以納稅人，包括individuals/個人，trusts/信托, and estates/遺產。Section 199A QBI deduction是線下扣除，從AGI中扣除。

QBI基本抵扣：20% × Qualified business income (QBI)

抵扣限制

QBI抵扣限制 01：兩者取大

1. 50 percent of W-2 wages for the business; or/工資的一半

2. 25 percent of W-2 wages for the business plus 2.5 percent of the unadjusted basis immediately after acquisition (UBIA) of all qualified property./工資的一半+UBIA×1.5%

QBI抵扣限制 02：兩者取小

1. Combined QBI deductions for all qualifying businesses; or/ 所有企業QBI的扣除額

2. 20% of the taxpayer's taxable income (before the QBI deduction) in excess of net capital gain./ 應納稅所得額（扣除QBI前）超過凈資本收益部分的20%。

根據納稅人的應納稅所得額的多少，計算Section 199A QBI Deduction的計算方法也不同。
