taxAlso known as: QBI, qualified business income deduction, Section 199A, 20% pass-through deduction
Updated · Written and reviewed by Konstantin Iakovlev
Detailed explanation
Originally enacted in TCJA 2017 with a 2025 sunset, OBBBA made QBI permanent. Phaseout thresholds for 2026: $251,800 single / $503,600 MFJ. Above that, "Specified Service Trades or Businesses" (lawyers, doctors, consultants, accountants, financial advisors) lose the deduction; non-SSTBs face a wage-and-property test. Below the threshold, all pass-through income qualifies. Real-estate rental income generally qualifies if it rises to the level of a "trade or business" (250+ hours of rental services per year safe harbor). Calculated on Form 8995 (simple) or 8995-A (complex).
