Section 199A Qualified Business Income Deduction: What Business Owners Need to Know

The Section 199A deduction—commonly called the Qualified Business Income Deduction or QBI deduction—can provide valuable federal tax savings for eligible business owners. It generally allows owners of pass-through businesses to deduct up to 20% of qualified business income on their individual tax returns.

Recent tax legislation made the deduction permanent and introduced important changes beginning with the 2026 tax year. Understanding the rules can help business owners identify opportunities, avoid calculation errors, and make better tax-planning decisions.

What Is the Section 199A Deduction?

Section 199A allows eligible taxpayers to deduct up to 20% of qualified business income earned through certain pass-through businesses.

A pass-through business generally does not pay federal income tax at the entity level. Instead, its income passes through to the owners and is reported on their individual tax returns.

Potentially eligible businesses include:

• Sole proprietorships and independent contractors
• Single-member LLCs
• Partnerships
• Multi-member LLCs taxed as partnerships
• S corporations
• Certain trusts and estates
• Some qualifying rental real estate activities

C corporations do not qualify for the deduction.

The deduction may also include 20% of qualified Real Estate Investment Trust dividends and qualified income from publicly traded partnerships.

Is the QBI Deduction Still Available?

Yes. The Section 199A deduction was originally scheduled to expire after 2025. However, the Working Families Tax Cuts legislation enacted in 2025 made it permanent.

This means eligible business owners can continue using the deduction after 2025 without the previous expiration date.

Beginning in 2026, the law also expands the income ranges over which certain limitations are gradually introduced and creates a new minimum deduction for some active business owners.

What Counts as Qualified Business Income?

Qualified business income is generally the net amount of income, gains, deductions, and losses connected with an eligible U.S. trade or business.

For a self-employed taxpayer, QBI often begins with the business’s net profit. However, several adjustments may be required before calculating the deduction.

Qualified business income generally does not include:

• W-2 wages received as an employee
• Reasonable compensation paid to an S corporation owner
• Guaranteed payments received by a partner
• Capital gains or capital losses
• Most dividends
• Interest income not properly connected to the business
• Income earned outside the United States that is not connected with a U.S. trade or business
• Certain annuity income

The QBI deduction reduces taxable income, but it does not reduce self-employment tax or adjusted gross income.

The Basic QBI Deduction Calculation

For a taxpayer whose income is below the applicable threshold, the deduction is generally the lesser of:

1. 20% of qualified business income; or
2. 20% of taxable income before the QBI deduction, reduced by net capital gain.

Simple example

Suppose a self-employed consultant has:

• $100,000 of qualified business income
• $120,000 of taxable income before the QBI deduction
• No net capital gain

Twenty percent of the taxpayer’s QBI is $20,000. Twenty percent of taxable income is $24,000.

Because the deduction is limited to the smaller amount, the potential QBI deduction would be $20,000.

Actual calculations may be more complicated when a taxpayer owns multiple businesses, carries forward a QBI loss, receives REIT dividends, or has income above the annual thresholds.

Section 199A Income Limits for 2026

The income limits are based on the taxpayer’s total taxable income before the QBI deduction—not simply the income generated by the business.

For the 2026 tax year, the thresholds are:

Taxpayers at or below the first threshold can generally calculate the deduction without applying the W-2 wage and qualified-property limitations.

For taxpayers within the phase-in range, the limitations apply gradually.

Once taxable income exceeds the top of the applicable range, the limitations apply fully. Owners of specified service businesses may lose the deduction entirely.

These figures are adjusted periodically for inflation, so taxpayers should use the limits applicable to the tax year being filed.

What Changes When Income Exceeds the Threshold?

When taxable income exceeds the applicable threshold, the deduction may be restricted by the business’s W-2 wages and qualified property.

For a non-SSTB, the business component of the deduction may be limited to the greater of:

• 50% of the W-2 wages properly allocable to the business; or
• 25% of those W-2 wages plus 2.5% of the unadjusted basis immediately after acquisition of qualified property.

Qualified property generally includes certain tangible, depreciable property used in producing qualified business income.

These rules can be particularly important for businesses that:

• Have few or no employees
• Pay independent contractors instead of W-2 employees
• Own significant buildings or business equipment
• Operate through an S corporation
• Are considering changes to payroll or business structure

The wage and property calculations should not be treated as a reason to make unnecessary purchases or increase payroll. The tax benefit must be evaluated alongside the actual cost and business purpose of each decision.

What Is a Specified Service Trade or Business?

A Specified Service Trade or Business, or SSTB, is a business in which the principal asset is generally the reputation or skill of one or more owners or employees.

SSTBs commonly include services in:

• Health
• Law
• Accounting
• Actuarial science
• Performing arts
• Consulting
• Athletics
• Financial services
• Brokerage services
• Investing and investment management
• Trading or dealing in securities, commodities, or partnership interests

Engineering and architecture are generally excluded from the SSTB classification.

An SSTB owner is not automatically disqualified from claiming the QBI deduction. If the owner’s taxable income is at or below the applicable threshold, the business may still qualify.

Within the phase-in range, the deduction is gradually reduced. Above the top of that range, QBI from the SSTB generally no longer qualifies.

Correctly classifying a business is essential, especially when it provides several different types of services.

The New $400 Minimum Deduction for 2026

Beginning with the 2026 tax year, certain active business owners may qualify for a minimum QBI deduction of $400.

To qualify, the taxpayer must generally:

• Have at least $1,000 of aggregate qualified business income from eligible businesses; and
• Materially participate in those businesses.

Material participation generally means the taxpayer is regularly, continuously, and substantially involved in operating the business. Passive investors may not qualify for this minimum deduction.

The $400 amount is scheduled to be adjusted for inflation after 2026.

This provision can be helpful to eligible small-business owners whose ordinary QBI calculation would otherwise produce a deduction below $400.

Can Rental Real Estate Qualify?

Rental income does not automatically qualify for the Section 199A deduction. The rental activity must generally rise to the level of a trade or business under federal tax principles.

The IRS also provides a safe harbor for certain rental real estate enterprises. Requirements can include:

• Maintaining separate books and records
• Completing a required number of rental-service hours
• Keeping contemporaneous records of services performed
• Attaching the required statement to the tax return

Some rental activities may qualify even if they do not meet the safe harbor, but eligibility depends on the facts and circumstances.

Certain arrangements—such as triple-net leases or property used personally during the year—may not qualify for the safe harbor.

Real estate owners should evaluate each property or rental enterprise carefully instead of assuming all rental income is QBI.

How Do Business Losses Affect the Deduction?

If the combined QBI from a taxpayer’s businesses is negative, the taxpayer generally cannot claim a QBI deduction for that year.

The negative amount is carried forward and treated as a loss from a qualified business in the following year. It reduces future positive QBI before another deduction can be calculated.

This carryforward is separate from other tax-loss rules, including net operating losses and passive-activity limitations.

Keeping accurate records of prior-year QBI losses is therefore important.

How Is the QBI Deduction Claimed?

The deduction is generally calculated using one of two IRS forms:

• Form 8995: Simplified calculation, generally used when taxable income is at or below the applicable threshold and other eligibility conditions are satisfied.
• Form 8995-A: More detailed calculation for taxpayers subject to wage, property, SSTB, aggregation, or other advanced limitations.

The final deduction is reported on the taxpayer’s individual income tax return.

The IRS corrected part of the Form 8995 instructions in February 2026, highlighting the importance of using the latest version of the form and its instructions when preparing a return.

Common QBI Deduction Mistakes

Business owners commonly encounter problems when they:

• Treat gross revenue as qualified business income
• Include S corporation owner wages in QBI
• Include a partner’s guaranteed payments
• Ignore the overall taxable-income limitation
• Use the business’s income instead of total taxable income when applying thresholds
• Misclassify an SSTB as a non-service business
• Fail to carry forward a prior-year QBI loss
• Assume every rental property automatically qualifies
• Calculate W-2 wages incorrectly
• Use an outdated income threshold
• Fail to consider income from a spouse when filing jointly

Because the deduction is calculated on the individual return, events outside the business—such as investment gains, retirement distributions, or a spouse’s wages—can affect the available deduction.

Tax-Planning Opportunities for Business Owners

The QBI deduction should be reviewed before the end of the tax year, when there may still be time to make appropriate adjustments.

Potential planning areas include:

Managing taxable income

Retirement-plan contributions, health savings account contributions, and other legitimate deductions may help manage taxable income around the Section 199A thresholds.

Reviewing S corporation compensation

An S corporation shareholder’s reasonable compensation is not QBI. However, setting compensation artificially low can create IRS compliance problems. Salary decisions should reflect the services performed and the business’s circumstances.

Evaluating W-2 wages and qualified property

For higher-income owners, payroll and eligible business property can significantly affect the deduction. These factors should be modeled before major purchases or staffing decisions are made.

Coordinating capital gains

Net capital gain can reduce the overall QBI limitation. Business owners planning to sell investments or other assets should consider how the gain could affect the deduction.

Considering aggregation

Taxpayers with multiple related businesses may be able to aggregate them for Section 199A purposes if specific requirements are met. Aggregation can sometimes improve the use of wages and qualified property, but the election has ongoing reporting requirements.

Why Professional QBI Planning Matters

The Qualified Business Income Deduction can appear straightforward when described as a 20% deduction. In practice, the result can depend on:

• Business structure
• Filing status
• Total household taxable income
• SSTB classification
• Owner compensation
• W-2 wages
• Qualified property
• Prior-year QBI losses
• Capital gains
• Rental real estate eligibility
• Material participation

A calculation made after the tax year ends may identify the deduction, but proactive planning can help protect or improve it.
