The Qualified Business Income (QBI) deduction under IRC §199A lets eligible Florida sole proprietors, S-corp shareholders, and partners deduct up to 20% of their qualified business income from federal taxes — a deduction worth $6,000–$30,000+ annually for many Florida small business owners. The rules are complex, with phase-outs and limitations based on income and business type. This guide explains who qualifies, how to calculate it, and strategies to maximize it.
The QBI deduction is available to: sole proprietors (Schedule C), partnerships/LLC members (K-1 income), and S-corp shareholders (K-1 income). It is NOT available to: C-corporations (which pay corporate tax on entity income), W-2 employees (even employees of their own C-corp), or trusts/estates above certain thresholds. The deduction is taken on Form 8995 (simple version) or 8995-A (complex version with limitations). The deduction exists through at least 2025 under the Tax Cuts and Jobs Act — extension beyond 2025 has been discussed in Congress. As of 2026, verify current law status.
Basic calculation: 20% of qualified business income. QBI = net business income from the pass-through entity, reduced by certain deductions. Example: Florida consultant with $120,000 in QBI can deduct $24,000, reducing taxable income to $96,000 and saving approximately $5,280 at the 22% marginal rate. The deduction is limited to 20% of taxable income minus net capital gains — so you can't claim more than 20% of your total individual income.
Above certain income thresholds (2026: approximately $197,300 single / $394,600 married filing jointly — inflation-adjusted), the deduction is subject to W-2 wage and qualified property limitations. Above the threshold, the deduction is limited to the greater of: 50% of W-2 wages paid by the business, OR 25% of W-2 wages + 2.5% of qualified property (UBIA). This limitation often results in a smaller QBI deduction for high-income S-corp owners with low W-2 wages — another reason the 'reasonable salary' determination matters.
Certain service businesses face a complete phase-out of the QBI deduction above the income threshold. Specified Service Trades or Businesses (SSTBs) include: health (physicians, dentists), law, accounting, financial services, consulting (where reputation is the main asset), and performing arts. Below the income threshold ($197,300/$394,600), SSTBs qualify for the full 20% deduction. Above the threshold, the SSTB deduction phases out completely. This dramatically affects high-income Florida professionals — a Florida attorney or physician with $400,000 in pass-through income may receive no QBI deduction.
For high-income Florida business owners: (1) Keep income below the phase-out threshold through retirement plan contributions (SEP-IRA, Solo 401(k)) and other above-the-line deductions; (2) Maximize W-2 wages paid through the S-corp to satisfy the W-2 wage limitation (particularly for non-SSTB businesses); (3) Separate SSTB and non-SSTB income streams (if a physician also rents property, the rental income may generate its own QBI deduction separately); (4) Consider whether grouping or aggregating multiple business activities changes the calculation.
The QBI deduction was enacted through 2025 under TCJA. Whether Congress extends it beyond 2025 (the 2026 tax year) depends on legislation. As of the knowledge cutoff, verify current law status with a CPA.
Yes — sole proprietors and self-employed individuals reporting on Schedule C qualify for the basic 20% deduction, subject to income phase-outs and SSTB limitations.
Yes — S-corp shareholders receive QBI through their K-1. W-2 wages they receive from the S-corp are not QBI — only the K-1 distributive share qualifies.
