Explanation

The QBI deduction applies to individuals, trusts, and estates receiving income from qualified trades or businesses operated through pass-through entities. The deduction is the lesser of 20% of QBI or 20% of taxable income (before the QBI deduction) minus net capital gains. Above certain income thresholds, the deduction is limited by W-2 wages paid and/or the unadjusted basis of qualified property. Specified service trades or businesses (SSTBs) — such as law, accounting, consulting, and financial services — are phased out at higher income levels.

Key Points

  • Deduction = up to 20% of qualified business income
  • W-2 wages and property basis limitations apply above income thresholds
  • SSTBs (law, accounting, consulting, health) phase out at higher income levels

Exam Tip

Below the threshold, all pass-through income qualifies for the full 20% deduction. Above the threshold, you must apply the W-2 wages/UBIA limitation.
