A Guide to the Business Pass-Through Deduction

The Section 199A pass-through deduction, also known as the Qualified Business Income (QBI) deduction, offers significant tax savings for eligible business owners. This deduction allows certain individuals to deduct up to 20% of their qualified business income from domestic businesses operated as a sole proprietorship, partnership, S corporation, trust, or estate. Understanding the intricacies of the Section 199A deduction can be complex, but it's vital for proper tax planning and compliance.

  • Basic Overview of the Section 199A Deduction

    o    Definition of Qualified Business Income (QBI): Qualified Business Income refers to the net amount of qualified items of income, gain, deduction, and loss from any qualified trade or business. It specifically excludes investment income, such as capital gains, dividends, and non-business interest income.

    o    Origins of the Section 199A Deduction: Enacted as part of the Tax Cuts and Jobs Act (TCJA) in 2017, the deduction was introduced to provide tax relief to businesses that do not benefit from the reduced corporate tax rate included in the TCJA. Initially scheduled to expire at the end of 2025, the One Big Beautiful Bill Act (OBBBA) made the deduction permanent, expanding its benefits.

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

    o    Qualified Trades or Businesses (QTB): The owners of these businesses are eligible for the full 20% deduction without income phaseouts if the businesses meet wage or property requirements. Common examples of QTBs include manufacturing, retail, and non-service-based businesses.

    o    Specified Service Trades or Businesses (SSTB): SSTBs include fields such as health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, and brokerage services. Professionals in these fields may face phaseouts on the deduction if their income exceeds specific thresholds.

    o    Congressional Intent for the Distinction: Historically, service industries have been treated differently from manufacturing under various tax codes. This distinction in Section 199A helps to target manufacturing and non-service-based industries for economic growth incentives.

  • Calculation Details and Income Thresholds

    o    Impact of Taxable Income: An individual’s taxable income directly affects the availability of the deduction for SSTBs. If a taxpayer's taxable income exceeds certain thresholds, the deduction is phased out proportionally, ultimately being unavailable at the top end. The OBBBA increased these thresholds, allowing more SSTB owners to qualify.

    o    Wage Impact on QTB Deduction: The deduction can be limited by wages paid by the business. For QTBs, the deduction is the lesser of 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’ qualified property.

  • Changes and Updates Under the OBBBA

    o    New Minimum Deduction Effective in 2026: Starting in 2026, a minimum deduction is introduced to ensure small business owners benefit from a baseline deduction, irrespective of wage or phaseout limitations. This enhancement aims to simplify tax planning for smaller QTBs and SSTBs with lower income or wage bases. The minimum deduction is$400 for taxpayers who have at least $1,000 of QBI from one or more active trades or businesses in which the taxpayer materially participates, and will be inflation-adjusted in future years. 

The Section 199A pass-through deduction serves as a vital tax planning tool for business owners, balancing incentives across various industries while promoting economic activity. It is also a very complicated deduction and tax professionals play a critical role in navigating these complexities to ensure compliance and optimization of benefits.
