The qualified business income deduction allows owners of pass-through businesses to deduct up to 20% of their qualified business income from their personal tax return. This deduction was created by the Tax Cuts and Jobs Act in 2017 and applies to sole proprietors, partnerships, S corporations, and some trusts and estates. The goal was to give pass-through business owners a tax benefit similar to the corporate tax rate reduction that C corporations received.

If you own a pass-through business, your share of business income flows through to your personal return. The QBI deduction reduces your taxable income by up to 20% of that qualified business income. For a business owner with $200,000 in qualified business income, that could mean a deduction of up to $40,000, which translates to real tax savings.

The deduction sounds straightforward, but eligibility and calculation become complicated at higher income levels. For 2024, the thresholds start at $191,950 for single filers and $383,900 for married filing jointly. Below these thresholds, most pass-through business owners can take the full 20% deduction without additional limitations.

Above those income thresholds, two factors start limiting your deduction. First, certain service businesses called Specified Service Trades or Businesses face a phase-out. This category includes law firms, accounting practices, consulting businesses, medical practices, and financial services. At high enough income levels, these businesses lose the deduction entirely. Second, non-service businesses face limitations based on W-2 wages paid and qualified property held by the business. The calculation uses the greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of qualified property basis.

Professional services firms in South Florida often find themselves in the complicated middle ground. Their income frequently exceeds the threshold, but the SSTB phase-out creates planning opportunities. Structuring the business correctly and timing income recognition can affect whether and how much of the deduction you receive.

The deduction is set to expire after 2025 unless Congress extends it. Tax planning for business owners should account for this uncertainty while still maximizing the current benefit.

Getting the QBI deduction right requires understanding your specific situation. Your business type, income level, wages paid, and assets owned all affect the calculation.
