The QBI deduction is one of the most valuable tax breaks available to self-employed Americans — and one of the least understood. A freelancer earning $80,000 net can cut their taxable income by $16,000 with a single line on Form 8995.
What the QBI Deduction Does
The Qualified Business Income (QBI) deduction, created under IRC Section 199A, allows pass-through business owners to deduct up to 20% of their qualified business income from federal taxable income. It does not reduce self-employment tax — only income tax.
Pass-through businesses include:
- Sole proprietorships (Schedule C)
- Single-member LLCs taxed as sole proprietors
- Multi-member LLCs taxed as partnerships
- S corporations
- Partnerships
- Qualified real estate investment trusts (REITs)
C corporations do not qualify. W-2 employees do not qualify.
The Basic Calculation
For most taxpayers below the income threshold, the deduction is straightforward:
QBI Deduction = 20% × Qualified Business Income
Where Qualified Business Income = net profit from your business (roughly your Schedule C net income, minus the deductible portion of self-employment tax and self-employed health insurance premiums).
Worked Example: Freelance Designer, $90,000 Net Income
| Step | Amount |
|---|---|
| Schedule C net profit | $90,000 |
| Minus deductible half of SE tax ($90,000 × 14.13% × 50%) | −$6,359 |
| Minus self-employed health insurance deduction | −$8,000 |
| Qualified Business Income | $75,641 |
| QBI Deduction (20% × $75,641) | $15,128 |
| Federal tax savings at 22% | $3,328 |
The deduction is claimed on Form 8995 (simple version) or Form 8995-A (complex situations). It reduces your taxable income but does NOT appear on Schedule C.
Income Thresholds and Phase-Outs (2026)
Below the threshold, there are no restrictions. Above the threshold, rules get complicated.
| Filing Status | Phase-In Begins | Full Phase-Out |
|---|---|---|
| Single / Head of Household | ~$197,300 | ~$247,300 |
| Married Filing Jointly | ~$394,600 | ~$494,600 |

For Taxpayers BELOW the Threshold
You get the full 20% QBI deduction. The only cap: your deduction cannot exceed 20% of your taxable income (before the QBI deduction). This only matters if your business income is unusually high relative to other income.
For Taxpayers ABOVE the Threshold — Two Different Rules
Rule 1 applies to SSTBs (Specified Service Trades or Businesses): The deduction phases out linearly over the $50,000 range above the threshold (or $100,000 for MFJ). Above the complete phase-out range, SSTB owners get zero QBI deduction.
Rule 2 applies to non-SSTBs 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 (depreciable business assets)
This W-2 wage limitation was designed to prevent high-income business owners from sheltering unlimited income. A sole proprietor with no employees and no W-2 wages could face a significant reduction.
SSTB: Is Your Business an SSTB?
| Type of Business | SSTB? | Notes |
|---|---|---|
| Freelance writer | No | Generally not SSTB |
| Graphic designer | No | Not SSTB |
| Software developer | No | Not SSTB unless providing consulting |
| Accountant (solo practice) | Yes | Accounting is specified |
| Attorney | Yes | Law is specified |
| Doctor / dentist / therapist | Yes | Health is specified |
| Financial advisor / planner | Yes | Financial services is specified |
| Consultant | Yes | Consulting is specified |
| Real estate agent | Depends | Brokerage: yes; property management: debated |
| Contractor / plumber | No | Trades are not SSTBs |
| Engineer | No | Explicitly excluded from SSTB |
| Architect | No | Explicitly excluded from SSTB |
If you are an SSTB below the income threshold, this distinction does not matter — you still get the full deduction.
How the Phase-Out Math Works (SSTB Example)
Scenario: Single attorney, $220,000 QBI, $210,000 taxable income
- Phase-in threshold: $197,300
- Income above threshold: $220,000 − $197,300 = $22,700
- Phase-out range: $50,000
- Phase-out percentage: $22,700 ÷ $50,000 = 45.4%
- Deduction reduction: 45.4%
- Allowable QBI deduction: 20% × $220,000 × (1 − 0.454) = $24,024 instead of $44,000
At $247,300+ income (full phase-out), this attorney gets zero QBI deduction.
Strategies to Maximize the QBI Deduction
1. Keep Income Below the Threshold
If your income is near the phase-in threshold, consider:
- Maximizing retirement contributions (SEP-IRA, Solo 401k) — these reduce AGI and QBI
- Timing income and expenses across years
- Deferring invoices to the following tax year if close to the limit
2. Convert to S-Corp (Non-SSTBs Above the Threshold)
An S-corp pays you a “reasonable salary” (W-2 wages) and passes remaining profit as a distribution. S-corp W-2 wages count toward the W-2 wage limitation — which can preserve or increase the QBI deduction for high earners who otherwise have no W-2 wages.
Example: $400,000 net profit, sole proprietor above threshold, no W-2 wages:
- QBI deduction limited by 50% of W-2 wages = $0
As an S-corp paying $120,000 salary:
- QBI deduction = 50% × $120,000 = $60,000 allowable
- At 37% rate: $22,200 in additional tax savings
The S-corp strategy has costs (payroll taxes, filings, accounting complexity) — it requires careful modeling to confirm net benefit.
3. SSTB Strategy: Keep Spouse’s Pass-Through as Non-SSTB
If a household has both SSTB and non-SSTB income, they are calculated separately. Non-SSTB income may still generate a QBI deduction even above the threshold (subject to W-2 limits).
How to Claim It: Form 8995
Most taxpayers use Form 8995 (simple version):
- Enter your QBI from each qualified business
- Multiply by 20%
- Apply the taxable income cap (20% of taxable income before QBI deduction)
- The result flows to Schedule 1, Line 13
Taxpayers with income above the phase-in threshold or multiple businesses use Form 8995-A, which is more detailed.
What QBI Deduction Does NOT Do
| Misconception | Reality |
|---|---|
| Reduces self-employment tax | No — SE tax is calculated before the deduction |
| Applies to W-2 wages you pay yourself (S-corp) | No — only the pass-through distribution qualifies |
| Reduces AGI | No — it is a below-the-line deduction reducing taxable income |
| Applies to capital gains | No — capital gains are excluded from QBI |
| Works with the standard deduction | Yes — you can take both |
