QBI Deduction Rules for 2026: What Business Owners Need to Know
The Qualified Business Income (QBI) Deduction remains one of the most valuable tax benefits available to eligible business owners in 2026. Under IRC Section 199A, many noncorporate taxpayers may deduct up to 20% of their qualified business income, potentially reducing their taxable income significantly.
New for 2026, the IRS has increased the income thresholds for inflation and introduced a minimum $400 QBI deduction for certain active business owners.
What Is the QBI Deduction?
The Section 199A deduction allows eligible individuals, trusts, and estates to deduct the lesser of:
- 20% of Qualified Business Income (QBI), or
- 20% of taxable income (excluding net capital gains).
The deduction is available whether you itemize deductions or claim the standard deduction.
It generally applies to income earned through:
- Sole proprietorships
- Single-member LLCs
- Partnerships
- S corporations
- Certain trusts and estates
C corporations and employee wages do not qualify.
2026 QBI Income Thresholds
For tax year 2026, the inflation-adjusted income thresholds are:
- Married Filing Jointly: $403,500
- Married Filing Separately: $201,775
- Single, Head of Household & Other Filers: $201,750
The phase-in ranges end at:
- Married Filing Jointly: $553,500
- Married Filing Separately: $276,775
- Single, Head of Household & Other Filers: $276,750
Above these limits, additional restrictions—including the W-2 wage and qualified property limitations—may reduce or eliminate the deduction.
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 new provision helps ensure that smaller active business owners continue to receive a meaningful tax benefit.
What Income Qualifies?
Qualified Business Income generally includes the net income, gains, deductions, and losses from an eligible U.S. trade or business.
However, several types of income are generally excluded, including:
- Capital gains and losses
- Dividend income
- Investment interest income
- Certain foreign currency gains
- Reasonable compensation from an S corporation
- Guaranteed payments to partners
- Payments received as an employee
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
If your taxable income falls below the applicable threshold, you may generally qualify for the full deduction.
As income rises within the phase-in range, the deduction is gradually reduced.
Once taxable income exceeds the upper phase-in limit, most SSTBs generally become ineligible for the QBI deduction.
W-2 Wage and Qualified Property Limitation
For higher-income taxpayers, the deduction is generally limited to the lesser of:
- 20% of Qualified Business Income, or
- 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 generally does not apply if taxable income is below the applicable threshold.
How to Claim the Deduction
Most taxpayers generally file:
- Form 8995 if taxable income is below the applicable threshold.
- Form 8995-A if taxable income exceeds the threshold or more complex calculations apply.
Owners of partnerships and S corporations generally receive the necessary QBI information on their Schedule K-1.
