Understanding the Qualified Business Income Deduction

The Section 199A pass-through deduction, commonly referred to as the Qualified Business Income (QBI) deduction, provides a notable opportunity for tax savings to qualifying business owners. This deduction allows individuals operating businesses as a sole proprietorship, partnership, S corporation, trust, or estate to deduct up to 20% of their qualified business income. Navigating the complexities of the Section 199A deduction is essential for effective tax planning and compliance in today's business environment.

  • Overview of the Section 199A Deduction

       Understanding Qualified Business Income (QBI): Qualified Business Income is defined as the net total of qualified income, gains, deductions, and losses from a qualifying trade or business. Notably, it excludes investment income such as capital gains, dividends, and passive income.

       Introduction of Section 199A: This deduction was introduced under the Tax Cuts and Jobs Act (TCJA) in 2017 to provide tax relief to businesses that did not benefit from the corporate tax rate reduction. Originally set to expire in 2025, the One Big Beautiful Bill Act (OBBBA) made the deduction permanent, thereby broadening its accessibility.

  • Differentiating Qualified Trades or Businesses (QTB) and Specified Service Trades or Businesses (SSTB)

       QTB: Owners of qualifying trades or businesses can claim the full 20% deduction without income phaseout constraints, provided they meet certain wage or property criteria. Typical examples include manufacturing and retail enterprises.

       SSTB: This category encompasses sectors such as healthcare, law, accounting, actuarial science, and financial services, among others. In these fields, professionals may find the deduction phases out based on income thresholds.

       Legislative Intent: Historically, the tax code has differentiated service industries from manufacturing industries, and Section 199A follows this precedent to promote economic incentives specifically for non-service sectors.

  • Calculation Methodology and Thresholds

       Effect of Taxable Income: A taxpayer's taxable income is a key determinant for accessing the SSTB deduction. When income surpasses certain limits, the deduction phases out, and at higher income levels, it ceases entirely. The OBBBA adjusted these thresholds to widen the scope for SSTB owners.

       Wage Considerations for QTB: For QTB deductions, the calculation is either 20% of QBI or a combination of 50% of wages paid, or 25% of wages plus 2.5% of the unadjusted basis of the business’s qualified property, whichever is smaller.

  • Recent Changes with the OBBBA

       Minimum Deduction Starting in 2026: A new baseline deduction will be introduced to ensure small business owners benefit, irrespective of wage or income factors. This strategic amendment looks to simplify tax planning for QTBs and SSTBs with modest income levels, by offering a baseline $400 deduction for those with $1,000 QBI or more. The amount will be adjusted for inflation in subsequent years.
