QBI Deduction 2026: How to Calculate Your 20% Qualified Business Income Deduction

A practical guide to Section 199A for self-employed individuals, LLC owners, S corporations, and real estate investors, with official 2026 figures and a step-by-step example.

Published: 🕒 Approximately 12 min read By Alfonso Luna Bentin
Key Takeaway: The Section 199A qualified business income (QBI) deduction lets eligible owners of sole proprietorships, partnerships, S corporations, and certain trusts and estates deduct up to 20% of their qualified business income, plus 20% of qualified REIT dividends and qualified publicly traded partnership (PTP) income. The One Big Beautiful Bill Act (OBBBA) made the deduction permanent and, starting with tax year 2026, widened the income phase-in ranges and added a $400 minimum deduction for taxpayers with at least $1,000 of QBI from active businesses in which they materially participate. For 2026, the limitations begin at $201,750 of taxable income ($403,500 married filing jointly). This article walks through the 2026 rules and the math, with the official sources listed at the end.

Why the QBI Deduction Matters for Business Owners in 2026

If you own a business that is not taxed as a C corporation, such as a sole proprietorship, partnership, S corporation, or an interest held through certain trusts and estates, there is a deduction you need to understand before you file your 2026 return. Under Section 199A of the Internal Revenue Code, you may be able to deduct up to 20% of your qualified business income. For many business owners it is one of the largest deductions available to them.

The One Big Beautiful Bill Act (OBBBA), enacted in 2025, made Section 199A permanent. It was previously scheduled to expire after 2025. OBBBA also made two changes that take effect for tax years beginning after December 31, 2025, which means they apply to your 2026 return:

  • Wider phase-in ranges. The range over which the SSTB rules and the W-2 wage and property limitation phase in grew from $50,000 to $75,000 (from $100,000 to $150,000 for joint returns).
  • A new $400 minimum deduction for taxpayers with at least $1,000 of QBI from active businesses in which they materially participate (explained below).

With more than 15 years working in taxes, accounting, finance, and business consulting, I have seen this deduction make a real difference for Schedule C filers, S corporation shareholders, and real estate investors alike. I have also seen business owners leave it on the table because they assumed they did not qualify, or claim it incorrectly because they did not understand the limitations. Both mistakes are expensive.

What Is the QBI Deduction and How Does It Work?

The QBI deduction is taken on your individual return (Form 1040) after adjusted gross income (AGI) is calculated. It is available whether you take the standard deduction or itemize on Schedule A, so you do not need to itemize to use it. However, it does not reduce your AGI. It reduces taxable income only. That matters because AGI drives other items on your return, such as certain phase-outs and thresholds, which the QBI deduction does not change. It also does not reduce net earnings from self-employment, so it does not lower self-employment tax.

The deduction has two components:

  1. The QBI component: generally 20% of the QBI from each qualified trade or business, subject to the SSTB rules and the W-2 wage and property limitation once taxable income is above the threshold.
  2. The REIT/PTP component: 20% of qualified REIT dividends and qualified PTP income. This component is not limited by W-2 wages or the unadjusted basis of qualified property. It has its own rules: for example, qualified REIT dividends exclude capital gain dividends and qualified dividend income and are subject to a holding period requirement, and PTP income from an SSTB is subject to the SSTB rules above the threshold.

The total of both components cannot exceed 20% of your taxable income before the QBI deduction, reduced by your net capital gain (which for this purpose includes qualified dividends). That overall cap is the limit many people forget.

What Counts as Qualified Business Income?

QBI is generally the net amount of qualified items of income, gain, deduction, and loss from a qualified trade or business that are effectively connected with a U.S. trade or business. It can include Schedule C profit, your share of partnership income, or S corporation pass-through income reported on Schedule K-1.

QBI is not always the same as your net profit. Deductions attributable to the business reduce QBI even when they are taken on Schedule 1 rather than on Schedule C. According to the IRS, these generally include the deductible part of self-employment tax, the self-employed health insurance deduction, and deductions for contributions to qualified retirement plans such as SEP, SIMPLE, and qualified plans.

QBI does not include:

  • Reasonable compensation paid to you by an S corporation (your W-2 wages)
  • Guaranteed payments paid to a partner for services
  • Capital gains and losses
  • Dividends and interest income not properly allocable to the business
  • Income not effectively connected with a U.S. trade or business
  • Qualified REIT dividends and qualified PTP income (these count in the separate REIT/PTP component instead)

Who May Qualify for the 20% QBI Deduction?

The deduction is potentially available to individuals, trusts, and estates with income from a qualified trade or business operated directly or through a pass-through entity. This includes:

  • Sole proprietors reporting on Schedule C
  • LLC owners taxed as sole proprietors, partnerships, or S corporations
  • S corporation shareholders reporting pass-through income on Schedule K-1
  • Partners reporting their distributive share on Schedule K-1
  • Certain rental property owners, if the rental activity rises to the level of a trade or business (more on this below)
  • Investors with qualified REIT dividends or qualified PTP income (REIT/PTP component)

If your 2026 taxable income before the QBI deduction is at or below $201,750 ($403,500 married filing jointly; $201,775 married filing separately), the SSTB rules and the W-2 wage and property limitation do not apply. Your QBI component is generally 20% of QBI, still subject to the overall taxable income cap.

New for 2026: The $400 Minimum Deduction

Starting in 2026, Section 199A(i) provides a floor. If you are an applicable taxpayer, your QBI deduction is the greater of $400 or the amount otherwise calculated. You are an applicable taxpayer for the year only if your aggregate QBI from active qualified trades or businesses is at least $1,000. An active qualified trade or business is one in which you materially participate under the passive activity rules of Section 469(h).

This floor does not apply automatically to every business. It does not help a taxpayer whose only business income comes from activities in which he or she does not materially participate, such as a passive investment in a partnership, and it does not apply when aggregate active QBI is under $1,000. For 2026, the $400 and $1,000 amounts are fixed; the IRS has stated they will be adjusted for inflation for tax years beginning after 2026. For most owners with meaningful profit, the regular calculation will already exceed $400, so the floor mainly matters for small or side businesses. Confirm how the floor is reported in the 2026 Form 8995 or 8995-A instructions.

Who May Face a Reduced Deduction or No Deduction?

Two major restrictions start once your taxable income exceeds the threshold for your filing status, and they phase in fully over the next $75,000 ($150,000 for joint returns).

Specified Service Trades or Businesses (SSTBs)

If your business is a specified service trade or business (SSTB), the QBI, W-2 wages, and property you can take into account are reduced through the phase-in range and eliminated above it. SSTBs include businesses in fields such as:

  • Health (for example, physicians, dentists, physical therapists)
  • Law
  • Accounting and tax preparation
  • Actuarial science
  • Consulting
  • Performing arts and athletics
  • Financial services and brokerage services
  • Investing and investment management, trading, or dealing in securities, partnership interests, or commodities
  • Any trade or business where the principal asset is the reputation or skill of one or more of its employees or owners

Engineering and architecture are specifically excluded from the SSTB definition. Below the threshold, SSTB status does not matter and SSTB owners compute the deduction like any other business.

Important Limitation For 2026, an SSTB owner with taxable income above $276,750 ($553,500 married filing jointly; $276,775 married filing separately) generally receives no QBI deduction from that SSTB. Review your situation with a qualified tax professional before assuming the deduction is available to you.

The W-2 Wage and Property (UBIA) Limitation

Above the threshold, the QBI component for each business is also limited to the greater of:

  • 50% of the W-2 wages paid by the business, or
  • 25% of the W-2 wages paid by the business plus 2.5% of the unadjusted basis immediately after acquisition (UBIA) of qualified property held by the business

Within the phase-in range, this limitation applies proportionally. Above the top of the range, it applies in full. It affects sole proprietors and single-member LLCs most directly, because a business with no employees pays no W-2 wages. If such a business also holds little qualified property, its QBI component can be reduced to zero once taxable income is above the range.

S corporations that pay their owner-employees reasonable compensation do generate W-2 wages, which is one reason entity structure matters for higher-income owners. Remember that the owner's salary itself is not QBI.

The 2026 Income Thresholds and Phase-In Ranges

The IRS published the 2026 amounts in Revenue Procedure 2025-32. They reflect the wider phase-in ranges enacted by OBBBA.

Section 199A thresholds for tax years beginning in 2026 (Rev. Proc. 2025-32)
Filing Status Limits begin above (threshold) Phase-in range Limits fully apply above
Married filing jointly $403,500 $150,000 $553,500
Married filing separately $201,775 $75,000 $276,775
All other returns (single, head of household, and others) $201,750 $75,000 $276,750
How the limitations apply at each income level (taxable income before the QBI deduction)
Taxable Income Level SSTB Impact W-2 Wage and UBIA Limit
At or below the threshold No restriction Does not apply
Within the phase-in range QBI, wages, and UBIA partially reduced Applies proportionally
Above the top of the range No deduction from the SSTB Applies in full

Step-by-Step Calculation Example: Schedule C Business Owner

The following is a simplified illustrative example using 2026 figures. Real calculations depend on the taxpayer's complete tax picture. This example does not represent a guaranteed result for any taxpayer.

$13,508

QBI deduction in this simplified 2026 example. It reduces taxable income; it is not a dollar-for-dollar tax savings.

Facts: Maria owns a single-member LLC taxed as a sole proprietorship and sells handmade goods online. She materially participates in the business. Her 2026 Schedule C net profit is $90,000. Her business is not an SSTB, has no employees, and holds no significant qualified property.

Assumptions stated for this example: Maria files as single, has no other income, takes the 2026 standard deduction of $16,100, did not contribute to a retirement plan, and did not claim the self-employed health insurance deduction. If she had made retirement contributions or paid self-employed health insurance, those deductions would reduce both her QBI and her taxable income, and the numbers below would change.

Calculation:

  1. Net earnings from self-employment: $90,000 × 92.35% = $83,115
  2. Self-employment tax: $83,115 × 15.3% = $12,716.60. The deductible half is $6,358 (rounded).
  3. QBI: $90,000 net profit minus the $6,358 deductible part of self-employment tax = $83,642. QBI is not simply the $90,000 Schedule C profit.
  4. AGI: $90,000 minus $6,358 = $83,642. Taxable income before the QBI deduction: $83,642 minus $16,100 = $67,542
  5. 20% of QBI: $83,642 × 20% = $16,728
  6. Overall cap, 20% of taxable income before QBI (Maria has no net capital gain): $67,542 × 20% = $13,508
  7. Her taxable income of $67,542 is below the $201,750 threshold, so the SSTB rules and the W-2 wage and UBIA limitation do not apply. The deduction is the smaller of steps 5 and 6: $13,508. It is above the $400 minimum, so the floor does not change the result.

Result: Maria's 2026 QBI deduction is $13,508, reducing her taxable income from $67,542 to $54,034. Her AGI stays at $83,642. Both amounts fall within the 2026 22% bracket for single filers ($50,400 to $105,700), so the simplified federal income tax effect is about $13,508 × 22% = $2,972. Her self-employment tax of $12,716.60 does not change. Actual results will vary with the full return.

Planning Tip

If your income is near the 2026 threshold, moves such as retirement contributions (SEP-IRA, Solo 401(k)) or timing deductible business expenses can lower taxable income. Keep in mind that retirement contributions attributable to the business also reduce QBI, so the net effect needs to be calculated, not assumed. Each situation requires analysis of the full picture.

How Does the QBI Deduction Apply to S Corporation Owners?

S corporation shareholders receive pass-through income on Schedule K-1, and that income may qualify as QBI, subject to the same thresholds and limitations. Two points matter. First, the reasonable compensation the S corporation pays you is W-2 wages, not QBI. Second, those W-2 wages, including your own salary, count toward the W-2 wage limitation once your taxable income is above the threshold. Too little salary can create IRS problems, and above the threshold, the salary level also changes the deduction.

If you are considering converting from a sole proprietorship to an S corporation, or reviewing your current S corporation salary, the interaction with the QBI deduction is part of the analysis. I work through this with business owners at Elite Tax Consulting regularly, and the right answer depends on your specific revenue, payroll, and filing situation.

Can Real Estate Investors Claim the QBI Deduction?

Rental income may qualify as QBI if the rental activity rises to the level of a trade or business under Section 162. That determination depends on the facts. Revenue Procedure 2019-38 offers a safe harbor under which a rental real estate enterprise is treated as a trade or business for Section 199A purposes if all of these requirements are met:

  • Separate books and records are kept for each rental real estate enterprise.
  • 250 or more hours of rental services are performed each year for an enterprise in existence less than four years. For an enterprise in existence four years or more, 250 hours must be met in any three of the five consecutive tax years ending with the current year. Rental services can be performed by owners, employees, agents, or contractors.
  • Contemporaneous records (time logs or similar documents) show the hours, the services performed, the dates, and who performed them.
  • A statement is attached to a timely filed original return for each year the safe harbor is used.

What counts as rental services: advertising, negotiating and executing leases, screening tenants, collecting rent, daily operation, maintenance and repairs, management, and supervising employees. What does not count: financial or investment management activities such as arranging financing, procuring property, reviewing financial statements, planning or managing capital improvements, and travel time.

Excluded from the safe harbor: property you also use as a residence under Section 280A(d), property rented under a triple net lease, property rented to a trade or business you or a related owner commonly control, and any portion of a property that is part of an SSTB. Failing the safe harbor does not automatically disqualify a rental; you can still establish trade or business status under the general rules.

Short-Term Rentals: QBI and Self-Employment Tax Are Separate Questions

Short-term rental owners often mix up two different analyses:

  • QBI eligibility asks whether the rental is a trade or business under Section 162 (or meets the Rev. Proc. 2019-38 safe harbor).
  • Self-employment tax asks whether the income is excluded rental income or income from providing substantial services primarily for the guest's convenience, such as regular cleaning during stays, changing linens, or maid service. When substantial services are provided, the IRS treats the activity as reported on Schedule C and subject to self-employment tax.

The answers are related, because providing substantial services is strong evidence of a trade or business, but one does not automatically decide the other. A rental can be QBI-eligible without being subject to self-employment tax. The passive activity rules, including the average-stay tests, are a third, separate analysis. Also note that a short-term rental you personally use enough to be treated as a residence under Section 280A(d) is excluded from the safe harbor.

Key Caution for Rental Owners Not every rental property qualifies for the QBI deduction, and the IRS can challenge the trade or business determination. Keep the books, time logs, and return statements described above if you rely on the safe harbor.

How Does the QBI Deduction Interact With Nevada's Tax Environment?

Nevada does not impose a personal income tax or a corporate income tax. Nevada business owners do not pay state income tax on their QBI or any other business income, so the QBI deduction is a federal deduction only and has no Nevada counterpart.

Nevada business owners are still subject to federal income tax and self-employment tax, and may owe two Nevada business taxes that the QBI deduction does not affect:

  • Commerce Tax: applies to businesses with Nevada gross revenue over $4,000,000 in a fiscal year (July 1 to June 30). The return is due 45 days after the fiscal year ends.
  • Modified Business Tax (MBT): a quarterly tax on wages paid by employers. For general businesses, the rate is 1.17% of wages above $50,000 per quarter. Financial institutions and mining businesses have different rules.

For Las Vegas business owners, the absence of state income tax is already an advantage. Optimizing the federal side, including correctly claiming the QBI deduction where eligible, is where meaningful tax reduction can occur.

What Records Should You Keep to Support the QBI Deduction?

Good Documentation Practice
  • Profit and loss statements or Schedule C records for each qualified business
  • Records of business-related adjustments that reduce QBI (self-employment tax, self-employed health insurance, retirement plan contributions)
  • W-2 forms and payroll records showing wages paid by each business
  • Records of the cost and placed-in-service date of qualified property (for the UBIA calculation)
  • Schedule K-1 forms showing Section 199A information from partnerships and S corporations
  • Brokerage statements identifying qualified REIT dividends and PTP income
  • Evidence of material participation if you rely on the $400 minimum deduction
  • For rentals using the safe harbor: separate books, contemporaneous time logs, and the return statement
  • Your completed Form 8995 or Form 8995-A

Which Form Do You Use: 8995 or 8995-A?

Under the rules in the most recent IRS instructions (for tax year 2025), you use the simplified Form 8995 if your taxable income before the QBI deduction is at or below the threshold for your filing status and you are not a patron of a specified agricultural or horticultural cooperative. Otherwise you use Form 8995-A, with its schedules for SSTBs, aggregation, loss netting, and cooperative patrons. Applying the same structure to 2026, the dividing line would be $201,750 ($403,500 married filing jointly; $201,775 married filing separately). Confirm against the 2026 instructions before filing, since the IRS may update the forms for the new minimum deduction.

Common Mistakes That Can Reduce or Eliminate Your QBI Deduction

  1. Using net profit as QBI. The deductible part of self-employment tax, self-employed health insurance, and retirement contributions attributable to the business reduce QBI.
  2. Counting items that are not QBI. S corporation wages, guaranteed payments, capital gains, and non-business interest are not QBI.
  3. Forgetting the overall cap. The total deduction cannot exceed 20% of taxable income before QBI, minus net capital gain.
  4. Assuming the $400 minimum applies to everyone. It requires at least $1,000 of QBI from active businesses in which you materially participate.
  5. Assuming rental income qualifies automatically. Without trade or business status or the safe harbor, rental income may not be eligible.
  6. Ignoring SSTB status and the W-2 wage and UBIA limitation above the threshold. A solo owner with no employees and little property can lose most or all of the deduction above the range.
  7. Filing the wrong form, or none. The deduction is calculated on Form 8995 or 8995-A.

What Should You Do Before Filing Your 2026 Return?

  • Confirm that each business is a qualified trade or business and whether it is an SSTB
  • Calculate QBI after the business-related adjustments, not just net profit
  • Project your 2026 taxable income and compare it with the $201,750 / $403,500 thresholds
  • Check whether you materially participate, in case the $400 minimum applies
  • Identify any qualified REIT dividends or PTP income on your brokerage statements
  • If you are above the threshold, gather W-2 wage and UBIA figures for each business
  • If you own rental property, confirm trade or business status or the safe harbor requirements, and keep your hour logs current
  • Schedule a review session before December 31, 2026 if you expect significant income changes or want to plan around the thresholds

Frequently Asked Questions About the QBI Deduction

No. The QBI deduction reduces taxable income only. It is available whether you itemize or take the standard deduction, but it does not reduce adjusted gross income, and it does not reduce net earnings from self-employment, so self-employment tax is unchanged.

For 2026, the limitations begin above $403,500 of taxable income for married filing jointly, $201,775 for married filing separately, and $201,750 for all other returns. They phase in over $150,000 for joint returns and $75,000 for all others, so they apply fully above $553,500, $276,775, and $276,750, respectively (Rev. Proc. 2025-32).

Starting in 2026, taxpayers with at least $1,000 of aggregate QBI from active qualified trades or businesses in which they materially participate receive a QBI deduction of at least $400. It does not apply to income from businesses in which you do not materially participate, and it does not apply if your active QBI is under $1,000.

Yes, on the qualified business income that passes through on Schedule K-1. The reasonable compensation you receive as a W-2 employee is not QBI, but the W-2 wages the S corporation pays, including yours, count toward the wage limitation if your taxable income is above the threshold.

Rental income may qualify if the activity is a trade or business under Section 162. Rev. Proc. 2019-38 provides a safe harbor that requires separate books, 250 or more hours of rental services (each year for enterprises under four years old, or in three of the last five years for older ones), contemporaneous records, and a statement attached to the return. Triple net leases and property used as a residence are excluded.

Yes. OBBBA made Section 199A permanent. It applies to the 2026 tax year (returns filed in 2027), with the wider phase-in ranges and the $400 minimum deduction that take effect for tax years beginning after December 31, 2025.
