What Counts as a Specified Service Under QBI
The Qualified Business Income deduction under Section 199A allows many pass-through entities to deduct up to 20% of qualified business income. However, the law carves out a category of businesses that the IRS calls "specified services." If your trade or business is a specified service, the QBI deduction may be limited or eliminated depending on your taxable income. Understanding this distinction is essential for any owner of a pass-through entity who wants to plan around the deduction accurately.

Specified services are businesses where the principal asset is the reputation or skill of one or more of its employees or owners. The IRS lists several categories explicitly, and the final one is a catch-all for any trade or business involving the performance of services in the fields of health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, or any trade or business where the principal asset is the reputation or skill of its employees.
How the QBI Deduction Works for Specified Services
For a specified service trade or business, the QBI deduction is subject to a wage and capital limitation. As taxable income rises, the deduction phases out. Once taxable income exceeds the threshold — $191,950 for single filers and $383,900 for married filing jointly for tax year 2024 — the deduction is reduced. At $241,950 for single filers and $483,900 for joint filers, the deduction is fully phased out for specified service businesses. Unlike non-specified service businesses, there is no dollar limit on wages paid; the phaseout is tied entirely to the owner's taxable income.
Which Businesses Are Most Likely to Be Classified as Specified Services
Certain professions are almost always classified as specified services because the value they deliver depends directly on personal expertise. The IRS has provided guidance on several categories:
- Health: doctors, dentists, veterinarians, psychologists, and other practitioners where the principal asset is personal skill.
- Law and accounting: lawyers, accountants, and firms where the work product is advice or representation based on specialized knowledge.
- Consulting and financial services: management consultants, financial planners, and brokerage firms where reputation and expertise drive client relationships.
- Performing arts and athletics: actors, musicians, athletes, and agents whose income is tied to personal brand and skill.
- Actuarial science: actuaries whose services are based on specialized mathematical and statistical expertise.
A business that sells products alongside these services may still be classified as a specified service if the principal asset remains the skill or reputation of its people. The IRS looks at the facts and circumstances, including the source of revenue and the nature of the work performed.
Planning Around the Specified Service Limitation
If your business is a specified service, you still have options to manage the impact on your QBI deduction. One approach is to structure compensation so that part of the income flows through wages subject to payroll tax rather than QBI, which can keep taxable income below the phaseout thresholds. Another strategy involves investing in capital assets that generate a return, since the wage and capital limitation for non-specified services allows a deduction based on the unadjusted basis of qualified property. However, for specified service businesses, the capital component does not provide the same relief once the income threshold is crossed.
Some owners explore restructuring by separating a specified service activity from a non-specified service activity within the same entity, but the IRS scrutinizes these arrangements carefully. The principal asset test applies to each trade or business as a whole, and artificial separation without a genuine change in operations is unlikely to survive an audit. Working with a tax professional who understands the interaction between QBI, W-2 wages, and capital is critical before making structural changes.
The Bottom Line
The QBI specified service rule is not a tax on the business itself but a limitation on the deduction available to the owner. If your taxable income is below the threshold, the deduction may still be fully available. As income grows, the phaseout reduces the benefit, and above the ceiling, the deduction is eliminated entirely. Knowing where your business falls on the specified service spectrum allows you to model income, plan for the phaseout, and make informed decisions about compensation and investment throughout the year.
