The Qualified Business Income (QBI) deduction — also known as the Section 199A deduction — lets eligible self-employed people and small business owners deduct up to 20% of their qualified business income from their federal taxable income. For someone earning $100,000 of self-employment income, that could mean deducting $20,000 — saving $4,400+ in federal income tax at the 22% bracket.
Key takeaway: The QBI deduction is one of the most significant tax benefits available to self-employed workers and small business owners. If you file a Schedule C, receive a K-1 from a partnership or S corporation, or have rental income treated as a business, you should check whether you qualify. The deduction was created by the Tax Cuts and Jobs Act of 2017 and is currently scheduled to expire after 2025 — verify its status at IRS.gov before filing your 2026 taxes, as legislative extension is possible.

What Counts as Qualified Business Income (QBI)?
QBI includes:
- Net profit from a Schedule C sole proprietorship
- Distributive share of partnership income (K-1)
- S corporation shareholder income (K-1)
- Qualified REIT dividends
- Qualified cooperative dividends
- Rental income treated as a trade or business
QBI does NOT include:
- W-2 wages from your employer (even if you also have self-employment income)
- Capital gains or losses
- Interest and dividend income (unless from a trade or business)
- Self-employment tax deduction
- Income earned as an employee
Who Are Specified Service Trades or Businesses (SSTBs)?
SSTBs are industries where the deduction phases out at higher incomes. If your business is an SSTB and your taxable income exceeds the threshold, your QBI deduction is reduced or eliminated.
SSTBs include:
- Health (physicians, dentists, veterinarians)
- Law (attorneys, paralegals)
- Accounting (CPAs, bookkeepers)
- Actuarial science
- Performing arts
- Consulting
- Athletics
- Financial services (investment advisors, brokers)
- Any business where the principal asset is the “reputation or skill” of its employees/owners
SSTBs do NOT include:
- Engineering
- Architecture
- Real estate sales (as a business)
- Insurance (as a business)
How to Calculate Your QBI Deduction
For most taxpayers (taxable income below the phase-out threshold):
QBI Deduction = 20% × Qualified Business Income
Example: Freelance graphic designer (not an SSTB) with $80,000 net Schedule C profit
- QBI = $80,000
- Deduction = $80,000 × 20% = $16,000
- This $16,000 is subtracted from taxable income on Form 1040
For taxpayers above the threshold (non-SSTB businesses):
The deduction is limited to the lesser of:
- 20% of QBI, OR
- The greater of:
- 50% of W-2 wages paid to employees by the business, OR
- 25% of W-2 wages + 2.5% of the unadjusted basis of qualified property
Example: Owner of an S-corp (non-SSTB) earning $500,000, MFJ, with $150,000 in W-2 wages paid to employees
- 20% of QBI = $100,000
- 50% of W-2 wages = $75,000
- Deduction is limited to $75,000 (the lesser of the two)
W-2 Wage and Property Limitation (High Earners)
If you are a sole proprietor with no employees, your W-2 wages paid = $0 — which means the W-2 wage limitation severely restricts or eliminates the QBI deduction once you are above the income threshold. This is one reason some self-employed people consider forming an S corporation as income grows — an S-corp owner takes a reasonable salary (creating W-2 wages) and takes the rest as distributions, allowing for a larger QBI deduction at higher incomes.
Filing the QBI Deduction — Form 8995 vs 8995-A
Form 8995 (Simplified):
- For single-business taxpayers
- Taxable income within phase-out range or fully below threshold
- Calculates deduction in a straightforward way
Form 8995-A (Complex):
- Multiple businesses
- Aggregation elections
- Above the income phase-out threshold
- Includes SSTB determination worksheets
Both forms flow to line 13 of Schedule 1 (Additional Income and Adjustments) → Form 1040.
Common Mistakes with the QBI Deduction
- Forgetting QBI is reduced by SE deduction: Your QBI for the deduction calculation is your net business income after the self-employment tax deduction (half of SE tax).
- Applying the deduction to W-2 wages: The 20% deduction only applies to qualified business income — not your salary from an employer.
- Ignoring the taxable income cap: The deduction cannot exceed 20% of your total taxable income (less capital gains and qualified dividends).
- Assuming rental income qualifies automatically: Rental income must meet the “safe harbor” requirements under IRS Notice 2019-07 to count as a qualified trade or business.
