The Tax Cuts and Jobs Act (TCJA) introduced one of the most impactful tax benefits for pass-through entities: the 20% Qualified Business Income (QBI) Deduction under Section 199A. This deduction allows eligible taxpayers, including owners of S Corporations, Partnerships, and Sole Proprietorships, to deduct 20% of their QBI on their personal tax returns. However, the rules surrounding this deduction are complex, particularly for Specified Service Trades or Businesses (SSTBs). This deduction is not available to C Corporations.
What is the Qualified Business Income Deduction?
Section 199A allows taxpayers to deduct 20% of qualified business income earned through a qualified trade or business. However, the deduction is limited to the greater of:
- 50% of W-2 wages with respect to the trade or business, or
- The sum of 25% of W-2 wages plus 2.5% of the unadjusted basis immediately after acquisition of all qualified property (typically tangible property subject to depreciation).
Additionally, the deduction is capped at taxable income for the year minus net capital gain and aggregate qualified cooperative dividends.
