Qualified Business Income Deduction
20% deduction for pass-through business income under IRC Section 199A for eligible self-employed taxpayers.
The Qualified Business Income (QBI) deduction, established by the Tax Cuts and Jobs Act under IRC Section 199A, allows eligible self-employed individuals, sole proprietors, partners, S corporation shareholders, and some trust and estate beneficiaries to deduct up to 20% of their qualified business income from their federal taxable income. It is designed to provide pass-through businesses with a tax rate benefit comparable to the 21% corporate rate reduction the TCJA delivered to C corporations.
For taxpayers below income thresholds ($182,050 single / $364,200 married filing jointly in 2024), the deduction is straightforward: 20% of QBI from all qualifying trades or businesses, limited to 20% of taxable income minus net capital gains. Qualified business income includes income, gains, deductions, and losses from qualifying domestic businesses—but excludes employee wages, capital gains and losses, investment income, and certain foreign income.
For taxpayers above the income thresholds, the deduction is subject to complex wage and property limitations: the deduction cannot exceed the greater of 50% of W-2 wages paid by the business, or 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property. These limitations effectively require qualifying businesses to pay meaningful wages or own significant depreciable property.
Specified Service Trades or Businesses (SSTBs)—including health, law, accounting, actuarial science, performing arts, consulting, athletics, and financial services—are phased out of the QBI deduction entirely for taxpayers above a higher income threshold, recognizing that these businesses' value derives primarily from the owner's personal services.
The QBI deduction is currently scheduled to expire after 2025 unless Congress extends it, making tax year 2025 potentially the last year to benefit from this provision.
FAQs
Does rental income qualify for the QBI deduction?
Rental income may qualify for the QBI deduction if the rental activity rises to the level of a trade or business under IRS guidelines. The IRS issued a safe harbor in Revenue Procedure 2019-38 stating that a rental enterprise qualifies if the taxpayer performs 250 or more hours of rental services per year (or the enterprise averages 250 hours over three of the last five years), maintains separate books, and the property is not rented to a commonly owned trade or business. Passive rental income for most small landlords does not automatically qualify, but with proper documentation, many can access the deduction.
How do the W-2 wage and property limitations affect the QBI deduction for higher-income taxpayers?
For taxpayers above the income thresholds, the QBI deduction cannot exceed the greater of: 50% of W-2 wages the business paid to employees, or 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property. This means businesses with no employees and minimal assets may receive little or no QBI deduction regardless of income level. Service businesses that rely entirely on the owner's labor (sole proprietors with no employees) face the most severe limitation—their QBI deduction can be substantially reduced or eliminated above the income threshold.
What is the difference between a qualified trade/business and a Specified Service Trade or Business for QBI purposes?
A qualified trade or business (QTB) for QBI purposes includes most businesses except SSTBs and the trade or business of being an employee. Specified Service Trades or Businesses (SSTBs) include health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, investing, and brokerage. The key distinction: SSTBs are fully excluded from the QBI deduction once the taxpayer's taxable income exceeds the upper income threshold. This means a doctor, lawyer, financial advisor, or management consultant at high income levels receives no QBI benefit, while an engineer, manufacturer, retailer, or real estate professional still qualifies.
