Which Businesses Do Not Qualify for the QBI Deduction?

Which Businesses Do Not Qualify for the QBI Deduction? The answer depends on more than the industry a business operates in. C corporation income does not qualify for the individual QBI deduction, employee wages are not QBI, and certain specified service trades or businesses (SSTBs) can lose the deduction at higher taxable-income levels. Certain investment income, capital gains, guaranteed payments, and other excluded items also do not count as qualified business income.

There is also an important point for 2026: SSTBs are not automatically excluded at every income level. The IRS applies taxable-income thresholds and a phase-in range. For tax year 2026, the threshold is $201,750 for most returns, $201,775 for married individuals filing separately, and $403,500 for married couples filing jointly. The phase-in ranges extend to $276,750, $276,775, and $553,500 respectively.

Which Businesses Do Not Qualify for the QBI Deduction? Understanding the Basic Rules

When asking Which Businesses Do Not Qualify for the QBI Deduction?, it is important to understand that QBI is calculated from qualifying income rather than simply from total business revenue.

The IRS explains that many owners of sole proprietorships, partnerships, and S corporations may be eligible for the deduction. However, income earned through a C corporation or income earned by providing services as an employee does not qualify.

A business generally needs to be a qualified domestic trade or business. The underlying activity must generally be conducted for profit and with continuity and regularity. Businesses that meet the relevant Section 162 trade-or-business standards can potentially generate QBI, while certain excluded businesses and income categories cannot.

This means a business owner should ask several questions before claiming the QBI deduction for small businesses:

• Is the business operated as a qualifying pass-through?
• Is the income actually QBI?
• Is the activity a qualified trade or business?
• Is the business an SSTB?
• What is the owner’s taxable income before the QBI deduction?

Are any wages, investment income, capital gains, or other excluded amounts being incorrectly included?

Answering these questions is more accurate than simply looking at the name of the business.

Which Businesses Do Not Qualify for the QBI Deduction? C Corporations

One of the clearest answers to Which Businesses Do Not Qualify for the QBI Deduction? is a business operated as a C corporation.

The income earned through a C corporation is not eligible for the individual Section 199A QBI deduction. The IRS specifically states that income earned through a C corporation is not eligible for this deduction.

This is different from an S corporation or partnership. S corporations and partnerships do not claim the individual QBI deduction at the entity level. Instead, information about qualifying income generally passes through to owners, who may determine their own eligibility.

For example, imagine two businesses that operate similar stores. One is organized as a sole proprietorship and the other as a C corporation. The business structure can result in different federal tax treatment, including different treatment under Section 199A.

This does not necessarily mean that one business structure is universally better than another. Choosing a business structure involves many factors, including liability, payroll, ownership, investment, state rules, and tax considerations.

Which Businesses Do Not Qualify for the QBI Deduction? S Corporation Clarification

An S corporation itself does not receive the individual QBI deduction. Instead, the necessary information is passed to shareholders through the tax reporting process.

Importantly, an S corporation shareholder’s reasonable compensation is generally not QBI. The qualifying business income component is determined separately from the shareholder’s employee compensation.

This distinction is important for S corporation QBI eligibility because business owners sometimes assume that their entire share of company income, including salary, automatically qualifies.

It does not.

The wages paid to the owner for services as an employee are treated separately from the QBI calculation.

Which Businesses Do Not Qualify for the QBI Deduction? Employee Income and Compensation

Another direct answer to Which Businesses Do Not Qualify for the QBI Deduction? is income earned as an employee.

The IRS states that services performed as an employee do not constitute a qualified trade or business for purposes of the QBI deduction. In other words, W-2 wages are not QBI.

This matters because someone can simultaneously be an employee and a business owner.

For example, suppose an individual earns $90,000 in W-2 wages from an employer and also earns $40,000 of qualifying net income from a separate sole proprietorship. The $90,000 salary is not QBI, while the qualifying income from the separate business may potentially be QBI.

The source of the income matters.

This is a common point of confusion when people research QBI deduction eligibility requirements. Owning a business does not turn every dollar earned by the owner into qualified business income.

Which Businesses Do Not Qualify for the QBI Deduction? Guaranteed Payments

Partnerships have another special issue.

Guaranteed payments to partners for services are generally not QBI. The IRS instructions distinguish qualifying business income from certain guaranteed payments and similar compensation arrangements.

Business owners should therefore separate partnership operating income from compensation or payment categories that are specifically excluded from QBI.

Good bookkeeping and accurate Schedule K-1 reporting are particularly important for partnership owners.

Which Businesses Do Not Qualify for the QBI Deduction? Specified Service Businesses

Specified service trades or businesses, commonly called SSTBs, are probably the most misunderstood part of Which Businesses Do Not Qualify for the QBI Deduction?

The IRS identifies several service fields as SSTBs, including:

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

The rules can also apply to certain businesses where the principal asset is the reputation or skill of one or more employees or owners.

Examples may include businesses receiving compensation for endorsements, licensing an individual’s identity or likeness, or certain media and appearance activities.

However, saying “SSTBs never qualify” would be incorrect.

The QBI rules include taxable-income thresholds that determine whether an SSTB is fully eligible, partially limited, or fully excluded.

Which Businesses Do Not Qualify for the QBI Deduction? 2026 SSTB Income Thresholds

For 2026, the QBI deduction income limits are important when determining Which Businesses Do Not Qualify for the QBI Deduction?

The IRS’s 2026 inflation-adjustment guidance lists the following thresholds and phase-in amounts:

If taxable income before the QBI deduction is at or below the applicable threshold, an SSTB can generally be treated as a qualified trade or business for purposes of the deduction. When taxable income falls within the phase-in range, the SSTB limitation is gradually applied. Once taxable income exceeds the upper end of the phase-in range, the SSTB is generally excluded.

This creates three broad situations.

• Below the threshold: The SSTB can generally qualify.
• Inside the phase-in range: Only part of the business may receive QBI treatment.
• Above the phase-in range: The SSTB is generally excluded from the QBI deduction.

Therefore, the question What businesses are excluded from QBI? cannot be answered accurately without looking at the owner’s taxable income.

Which Businesses Do Not Qualify for the QBI Deduction? Examples of SSTBs

A doctor, lawyer, accountant, consultant, financial professional, or other listed professional may operate an SSTB.

But being in one of those professions does not automatically eliminate QBI eligibility.

For example, a qualifying consulting business owned by a taxpayer below the 2026 taxable-income threshold can generally receive QBI treatment. As taxable income moves through the phase-in range, the amount treated as qualified business income can be reduced. Above the upper threshold, the SSTB is generally excluded.

This is an important distinction for articles about SSTB tax rules because many simplified explanations incorrectly state that all professional businesses are excluded.

Which Businesses Do Not Qualify for the QBI Deduction? Consulting Businesses

Consulting deserves special attention when discussing Which Businesses Do Not Qualify for the QBI Deduction?

The IRS specifically includes consulting within the SSTB definition.

However, not every business that uses the word “consulting” in its name should automatically be treated as an SSTB without reviewing its actual activities.

The nature of the service matters. A business may provide consulting alongside other activities, and the applicable tax rules may require the activities to be analyzed separately or under the aggregation rules.

For example, a business may sell software while also providing implementation advice. Another business may provide general marketing consulting services. The facts and the actual services performed need to be reviewed when determining whether the SSTB definition applies.

This is why business owners should not make a tax classification based only on a website description, business name, or job title.

Which Businesses Do Not Qualify for the QBI Deduction? Investment and Capital Income

Another important question is whether every dollar associated with a business is QBI.

The answer is no.

Certain types of investment income are excluded from QBI. The IRS guidance identifies items such as certain capital gains and losses, dividends, interest income that is not properly allocable to a trade or business, and other specified categories as excluded from QBI.

For example, a business owner’s investment portfolio does not become QBI simply because that person owns an operating company.

Similarly, a capital gain from selling an asset can have different tax treatment from ordinary business operating income.

This distinction makes qualified business income different from gross revenue.

A business owner should therefore avoid calculating QBI simply by taking total sales and multiplying the result by 20%.

The deduction is based on qualifying net income after taking applicable adjustments and exclusions into account.

Which Businesses Do Not Qualify for the QBI Deduction? Rental Real Estate

Rental real estate is another area where the answer to Which Businesses Do Not Qualify for the QBI Deduction? requires more detail.

Rental property is not automatically excluded.

The IRS explains that ownership and rental of real property can constitute a trade or business when the applicable Section 162 requirements are satisfied. Certain rental real estate enterprises may also qualify under the safe harbor established by Revenue Procedure 2019-38.

At the same time, a rental activity that does not satisfy the relevant requirements should not automatically be included in QBI.

This means landlords need to examine how their rental activities are structured and operated.

Factors such as regularity, continuity, management activities, documentation, and the nature of the rental operation can matter.

The rental real estate QBI deduction therefore depends on the facts rather than a blanket rule that all rental income either qualifies or does not qualify.

Which Businesses Do Not Qualify for the QBI Deduction? Non-Business Activities

An activity must generally rise to the level of a trade or business to generate QBI.

The IRS explains that, under Section 162 principles, the primary purpose of the activity should be earning income or profit and the activity should be conducted with continuity and regularity.

This can matter for casual or occasional activities.

For instance, selling a few unused personal belongings online is not automatically the same as operating a regular online retail business.

A person who operates a continuous, organized ecommerce operation for profit may potentially have a qualifying trade or business. Someone simply disposing of personal property generally does not.

The distinction between a hobby and business for tax purposes can involve facts and circumstances, so taxpayers should avoid assuming that every money-making activity produces QBI.

Which Businesses Do Not Qualify for the QBI Deduction? Other Excluded Income

Even when the underlying business qualifies, certain income items can still be excluded.

Examples include:

• W-2 wages: Compensation as an employee is not QBI.
• S corporation reasonable compensation: W-2 compensation paid by an S corporation to an owner is separate from QBI.
• Guaranteed payments: Certain partnership payments are excluded.
• Capital gains: Certain capital gains and losses are not QBI.
• Dividends: Certain dividend income does not count as QBI.
• Unrelated investment interest: Interest not properly connected to a trade or business may be excluded.
• Certain annuity income and other specified items: The tax rules contain additional exclusions.

This demonstrates why a proper QBI calculation requires more than simply looking at revenue.

Which Businesses Do Not Qualify for the QBI Deduction? REIT and PTP Income

There is an important exception to the basic explanation.

The IRS states that eligible taxpayers can also receive a separate 20% deduction component for qualifying REIT dividends and publicly traded partnership (PTP) income, subject to the applicable rules and taxable-income limitations.

These items are not ordinary QBI from a qualified trade or business, but Section 199A provides a separate deduction component for qualifying amounts.

This distinction is useful when researching Section 199A eligible income because a taxpayer can have a QBI deduction even when part of the deduction comes from REIT or PTP income rather than a traditional operating business.

The rules can be complex, especially when losses or multiple sources of income are involved.

Here is a simplified comparison:

This table is a general overview rather than a tax determination. Actual treatment can depend on taxable income, business activities, entity structure, qualified property, W-2 wages, aggregation, and other rules.

How to Check Your Eligibility?

If you are trying to determine Which Businesses Do Not Qualify for the QBI Deduction?, use a step-by-step review.

• First, identify your business entity.
• Second, separate operating business income from wages, investment income, capital gains, and other sources.
• Third, determine whether the activity is a genuine trade or business conducted for profit with continuity and regularity.
• Fourth, check whether the activity is an SSTB.
• Fifth, calculate taxable income before the QBI deduction.
• Sixth, check the 2026 threshold and phase-in amounts.

Finally, review W-2 wage and qualified-property limitations that can apply to higher-income taxpayers.

Form 8995 is generally used for eligible taxpayers who meet the simplified requirements, while Form 8995-A is used for more complex QBI situations.

For businesses involving multiple activities, owners, entities, or large amounts of income, professional tax advice can be especially useful.

Common Mistakes to Avoid:

Many QBI mistakes come from oversimplifying the rules.

One common mistake is saying that all doctors, lawyers, or consultants are automatically excluded. SSTBs are subject to income-based rules, so the owner’s taxable income must be considered.

Another mistake is treating all S corporation income as QBI. Owner compensation is generally separate from QBI.

A third mistake is treating investment income or capital gains as business income.

Another issue is using outdated QBI thresholds. For 2026, the thresholds are different from 2025.

Finally, business owners should not automatically treat rental income as QBI without checking whether the rental activity qualifies as a trade or business or satisfies the relevant safe harbor.

Call to Action:

Understanding Which Businesses Do Not Qualify for the QBI Deduction? can help small business owners avoid incorrect assumptions when planning their taxes.

Start by reviewing your business structure, income sources, taxable income, business activities, and whether the company falls within an SSTB category. Keep your bookkeeping and tax records organized so your accountant can clearly identify QBI and excluded income.

Before filing your 2026 return, check the latest IRS Form 8995 and Form 8995-A instructions and consider consulting a qualified tax professional when your business involves an SSTB, multiple entities, rental real estate, significant income, or complex pass-through reporting.

Closing Thoughts:

The answer to Which Businesses Do Not Qualify for the QBI Deduction? is more detailed than a simple list of industries.

C corporation income does not qualify for the individual Section 199A deduction, and employee wages do not constitute QBI. SSTBs—including businesses in health, law, accounting, consulting, financial services, and other listed fields—are subject to special rules based on taxable income.

At the same time, it would be incorrect to say that every professional service business automatically loses the deduction. For 2026, eligible SSTBs below the applicable taxable-income threshold can generally be treated as qualified businesses, while the limitation is phased in over a specified income range and becomes fully applicable above that range.

Other income can also be excluded even when a business itself qualifies. Wages, certain guaranteed payments, capital gains, dividends, and certain investment-related income may not be included in QBI. Rental real estate requires its own analysis to determine whether the activity qualifies as a trade or business.

For 2026, business owners should pay particular attention to the updated income thresholds and the new minimum-deduction framework. Because the IRS’s 2026 Form 8995 materials are currently identified as draft, the final forms and instructions should be checked before filing.
