QBI Deduction — Section 199A
The permanent 20% deduction on qualifying pass-through business income — one of the largest tax benefits available to business owners, professionals, and real estate investors. Available every year with the right structure.
Section 199A allows owners of pass-through businesses — S corporations, partnerships, LLCs, and sole proprietors — to deduct 20% of their qualified business income directly on their personal tax return. On $500,000 of qualifying income, that is a $100,000 deduction, saving $37,000 in federal taxes at the top rate. It is available every year and was made permanent under the One Big Beautiful Bill Act in 2025.
Most professional service businesses — law firms, medical practices, financial advisors, consultants — are classified as "specified service trades or businesses" (SSTBs). For SSTBs, the QBI deduction phases out for high earners: it begins to phase out at $201,750 for single filers and $403,500 for married filers, and disappears entirely at $276,750 and $553,500 respectively.
For non-SSTB businesses — real estate, manufacturing, retail, restaurants, most service businesses that are not on the SSTB list — the deduction is available at any income level, subject to W-2 wage and property limitations.
The key insight: even if your primary business is an SSTB, other income streams you own may qualify for the full QBI deduction. A physician whose medical practice is an SSTB may also own a real estate management company, a medical equipment leasing entity, or a real estate portfolio — none of which are SSTBs. Those entities generate QBI that qualifies for the 20% deduction regardless of the physician's total income. We identify and maximize these non-SSTB income streams for every client whose primary business is an SSTB.
- 20% deduction on qualifying business income reduces effective tax rate from 37% to approximately 29.6% on pass-through income — a permanent, annually recurring benefit.
- Available on rental real estate income in addition to business income — rental income from investment properties qualifies if treated as a trade or business, significantly expanding the deduction base for real estate investors.
- For non-SSTB businesses, no income cap — the deduction is available at any income level subject only to the W-2 wage and property limitations at higher incomes.
- Can be combined with a defined benefit plan — reducing QBI first with the DB plan contribution, then applying the 20% deduction to the remaining QBI.
- SSTB phase-out: for specified service businesses, the deduction phases out completely above $553,500 of taxable income (married) in 2026. Physicians, attorneys, accountants, and financial advisors above this threshold lose the deduction on their primary practice income.
- W-2 wage limitation: for non-SSTB businesses with taxable income above the threshold, the deduction is limited to the greater of 50% of W-2 wages paid or 25% of W-2 wages plus 2.5% of qualified property. S corporation owners who set salary too low may lose QBI benefit.
- Does not reduce self-employment tax — only income tax. S corporation structure eliminates SE tax on distributions separately from QBI.
- Does not apply to capital gains, dividends, interest income, or wage income — only to qualified business income from a pass-through entity.
SSTB classification analysis
We determine whether each business entity is an SSTB. The classification is not always obvious — consulting businesses, coaching businesses, and certain service companies may or may not qualify as SSTBs depending on their specific activities. We review each entity and identify whether any reclassification or restructuring is warranted.
Shurek — annual review for every pass-through entityIdentify non-SSTB income streams to maximize
For high-income SSTB owners whose primary business income exceeds the phase-out threshold, we identify and structure ancillary income streams that qualify for the full deduction — real estate entities, management companies, non-SSTB subsidiaries. These represent QBI that does not phase out regardless of total income.
Shurek — strategic structuring in coordination with entity architectW-2 wage optimization for non-SSTB businesses
For business owners above the income threshold whose deduction is limited by W-2 wages, we model the optimal W-2 wage level that maximizes the QBI deduction without triggering excessive FICA exposure. The optimal salary is often different from "reasonable compensation" minimums.
Shurek — modeled annually before year-endCoordinate with defined benefit plan to reduce taxable income below phase-out
For SSTB owners near the phase-out threshold, a defined benefit plan contribution reduces taxable income — potentially pulling it below the SSTB phase-out and restoring QBI eligibility. We model this interaction annually in Q4 to identify whether additional contributions before year-end would restore the QBI deduction.
Shurek — Q4 planning call with every SSTB client near the threshold| Form | Name | When Due | What It Does and Why It Matters |
|---|---|---|---|
| 1040 | Individual Income Tax Return | April 15 (extension to October 15) | The QBI deduction is claimed on Form 1040 via Schedule QBI. It reduces your taxable income directly — the 20% deduction appears as a reduction to adjusted gross income on the face of the return. Getting this right requires properly computing QBI from every qualifying entity, applying SSTB limitations where applicable, and coordinating the W-2 wage limitation calculation. We prepare Form 1040 with the complete QBI computation for every pass-through entity client. |
| Schedule QBI (Form 8995 or 8995-A) | Qualified Business Income Deduction | Filed with Form 1040 | Form 8995 (simple version) or 8995-A (complex version with multiple entities or W-2 wage limitations) computes the QBI deduction. For clients with multiple entities — some SSTB, some not — Form 8995-A is required and involves entity-by-entity QBI computation, aggregation election analysis, and W-2 wage limitation calculations. We prepare this form as part of every business owner's return. |
| 1120-S or 1065 | S Corporation or Partnership Return | March 15 (extension to September 15) | The QBI flowing to the individual return starts here. Each entity return separately states the owner's allocable share of QBI, W-2 wages, and qualified property on the Schedule K-1. These figures feed directly into the Form 8995-A calculation on the personal return. Errors or omissions on the entity return flow through to the QBI deduction — making accurate entity return preparation essential to the personal return. |
Annual SSTB classification review for every entity. Phase-out threshold analysis and DB plan coordination modeling in Q4. W-2 wage optimization for non-SSTB businesses above the threshold. Aggregation election analysis for clients with multiple qualifying entities. Form 8995-A preparation with full multi-entity QBI computation. K-1 coordination between entity returns and personal return to ensure consistent QBI reporting.
The QBI deduction is available every year but must be optimized before December 31. The decisions that affect it — salary levels, DB plan contributions, and entity income levels — cannot be changed after year-end.
Model Projected QBI and Phase-Out Position
For SSTB clients, project where taxable income will land relative to the phase-out threshold. Identify whether additional DB plan contributions would restore QBI eligibility. This analysis drives year-end action.
W-2 Salary Confirmation
S corporation owner-employees must have their W-2 wage paid by December 31 to count toward the W-2 wage limitation. Salary changes cannot be retroactive. We confirm optimal salary level before this deadline.
Year-End Income and Deduction Finalized
All decisions affecting QBI — DB plan contributions, business expenses, S corp distributions vs. salary — must be finalized by December 31. No retroactive changes are available after year-end.
Entity Returns Due — K-1s with QBI Data Issued
K-1s must clearly report each owner's QBI, W-2 wages, and qualified property. Errors flow through to the personal return. We prepare all entity returns with proper K-1 QBI disclosure.
Form 1040 with Form 8995-A Filed
Full QBI computation across all entities, SSTB limitations applied, W-2 wage limitation calculated. The deduction appears here and reduces federal taxes directly.
Entity Structure Review
As income grows or changes, the optimal entity structure for QBI may change. We review annually whether aggregation elections, new entity creation, or restructuring would expand QBI eligibility.
