How the QBI Deduction Works in 2026
The Qualified Business Income (QBI) Deduction, also known as the Section 199A deduction, continues to provide valuable tax savings for eligible business owners in 2026. Qualified taxpayers may deduct up to 20% of qualified business income (QBI), potentially reducing taxable income without itemizing deductions.
For 2026, updated income thresholds and a new minimum $400 deduction make it even more important for business owners to understand how the deduction works.
What Is the QBI Deduction?
The Section 199A deduction generally allows eligible noncorporate taxpayers to deduct the lesser of:
- 20% of qualified business income (QBI), or
- 20% of taxable income after reducing it by net capital gains.
The deduction may also include 20% of qualified REIT dividends and 20% of qualified publicly traded partnership (PTP) income, subject to applicable limitations.
The deduction is generally available to owners of:
- Sole proprietorships
- Single-member LLCs
- Partnerships
- S corporations
- Certain trusts and estates
Generally, C corporations and employee wage income do not qualify.
What Counts as Qualified Business Income?
Qualified Business Income generally includes the net income, gains, deductions, and losses from a qualified U.S. trade or business.
Items that are generally not included in QBI include:
- Capital gains and losses
- Dividend income
- Investment interest income
- Nonbusiness annuity income
- Reasonable compensation paid by an S corporation
- Guaranteed payments to partners
- Certain partnership payments for services
Business-related deductions—such as deductible self-employment tax, self-employed health insurance, retirement plan contributions, and deductible business interest—generally reduce QBI.
2026 Income Thresholds
The QBI deduction becomes more restrictive as taxable income increases.
For the 2026 tax year, the thresholds are:
- Married Filing Jointly: $403,500
- Married Filing Separately: $201,775
- Single, Head of Household & Other Filers: $201,750
The phase-in range ends at:
- Married Filing Jointly: $553,500
- Married Filing Separately: $276,775
- Single, Head of Household & Other Filers: $276,750
Your taxable income determines whether additional limitations apply.
W-2 Wage and Qualified Property Limitation
For higher-income taxpayers, the deduction may be limited to the greater of:
- 50% of W-2 wages paid by the business, or
- 25% of W-2 wages plus 2.5% of the unadjusted basis immediately after acquisition (UBIA) of qualified business property.
This limitation:
- Does not apply below the income threshold.
- Gradually phases in as taxable income increases.
- Applies in full once taxable income exceeds the phase-in ceiling.
Specified Service Trade or Business (SSTB) Rules
Special rules apply to Specified Service Trades or Businesses (SSTBs), including:
- Health care
- Law
- Accounting
- Consulting
- Financial services
- Brokerage services
- Performing arts
- Athletics
- Investment management
For 2026:
- Below the income threshold, SSTBs generally qualify for the full deduction.
- Within the phase-in range, the deduction is gradually reduced.
- Above the phase-in ceiling, most SSTBs generally become ineligible for the QBI deduction.
Special Rules for Rental Real Estate
Rental real estate may qualify for the QBI deduction if it rises to the level of a trade or business.
Certain commonly controlled rental activities may also qualify under applicable IRS safe harbor guidance, provided the required conditions are met.
New Minimum QBI Deduction for 2026
Beginning in 2026, eligible taxpayers may qualify for a minimum $400 QBI deduction if they:
- Have at least $1,000 of aggregate qualified business income, and
- Materially participate in one or more active qualified trades or businesses.
This provision helps ensure many active small business owners receive a meaningful tax benefit even when the standard QBI calculation would otherwise produce only a small deduction.
How to Claim the Deduction
Most taxpayers generally use:
- Form 8995 if taxable income is at or below the applicable threshold.
- Form 8995-A if taxable income exceeds the threshold or more detailed calculations are required.
Owners of partnerships and S corporations typically receive the information needed to calculate the deduction through Schedule K-1.
