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 their 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 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 qualified publicly traded partnership (PTP) income.
This deduction is available to:
- Sole proprietors
- Single-member LLCs
- Partnership owners
- S corporation shareholders
- Certain trusts and estates
C corporations and employee wages do not qualify.
What Counts as Qualified Business Income?
Qualified Business Income generally includes the net income, gains, deductions, and losses from an eligible U.S. trade or business.
However, the following items are generally excluded:
- Capital gains and losses
- Dividend income
- Investment interest
- Nonbusiness annuity income
- Reasonable compensation paid by an S corporation
- Guaranteed payments to partners
- Certain partnership service payments
Business-related deductions such as self-employed health insurance, deductible self-employment tax, retirement contributions, and business interest generally reduce QBI.
2026 Income Thresholds
The QBI deduction becomes more restrictive as taxable income increases.
For tax year 2026, the thresholds are:
- Married Filing Jointly: $403,500
- Married Filing Separately: $201,775
- Single, Head of Household & Others: $201,750
The phase-in range ends at:
- MFJ: $553,500
- MFS: $276,775
- Single/HOH: $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 of qualified business property (UBIA).
This limitation:
- Does not apply below the income threshold.
- Gradually phases in as income increases.
- Applies in full once taxable income exceeds the phase-in ceiling.
Specified Service Trade or Business (SSTB) Rules
Special rules apply to professional service businesses, including:
- Health care
- Law
- Accounting
- Consulting
- Financial services
- Brokerage services
- Performing arts
- Athletics
- Investment management
For 2026:
- Below the threshold, SSTBs generally qualify for the full deduction.
- Within the phase-in range, the deduction is gradually reduced.
- Above the phase-in ceiling, 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 the IRS safe harbor rules.
New Minimum QBI Deduction for 2026
Beginning in 2026, eligible taxpayers may receive 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 new provision helps ensure active small business owners receive a minimum tax benefit.
How to Claim the Deduction
Most taxpayers use:
- Form 8995 if taxable income is below the threshold.
- Form 8995-A if income exceeds the threshold or more detailed calculations are required.
Owners of partnerships and S corporations receive the necessary QBI information through Schedule K-1.
