There is a deduction that can knock up to 20 percent off the taxable business income of a freelancer, a landlord running a real rental business, or a main-street shop owner, and it requires no receipts, no itemizing, and no special spending. It is the qualified business income deduction, often called QBI or the Section 199A deduction, and a surprising number of eligible people have never heard of it because it happens quietly on a form most tax software fills in automatically.
It is worth understanding anyway, because the deduction has edges: income limits where the rules tighten, types of income that never qualify, and a service-business category that can lose the break entirely at higher incomes. The IRS overview lives on its qualified business income deduction page, and what follows is the plain-English version.
What the deduction is
The QBI deduction lets eligible taxpayers deduct up to 20 percent of their qualified business income from a pass-through business. Pass-through means the business itself pays no corporate tax; the profit passes through to your personal return. That covers sole proprietorships (your Schedule C income), partnerships, S-corporations, and LLCs taxed as any of those. Income earned as a W-2 employee never qualifies, and neither does profit from a C-corporation, which pays its own corporate tax instead.
Created by the 2017 tax law, the deduction was originally scheduled to expire after 2025. Congress made it permanent in the tax law enacted in July 2025, so in 2026 it remains a standing feature of the code rather than a countdown clock, one less thing for small business owners to game out.
What counts as qualified business income
QBI is the net amount of qualified income, gains, deductions, and losses from your U.S. business. Think of it as your business profit, with some items stripped out. It does not include capital gains or losses, most dividends, interest income unrelated to the business, or wages you pay yourself. For S-corp owners, the reasonable salary you take is W-2 income and is excluded; only the remaining business profit can be QBI. Guaranteed payments to partners are likewise excluded.
One more piece: qualified dividends from real estate investment trusts and certain publicly traded partnership income get their own 20 percent component of the same deduction, even though they are investments rather than businesses you run.
The 20 percent has a second ceiling
The deduction is up to 20 percent of QBI, but it can never exceed 20 percent of your taxable income minus net capital gains. In practice, whichever number is smaller wins. If your business earned $50,000 but your taxable income after the standard deduction is $38,000, the deduction is figured against the smaller base. This is also why the QBI deduction cannot zero out your tax by itself: it trims taxable income, and it does nothing to reduce self-employment tax, which is calculated separately.
Where the income thresholds change the game
Below an annual taxable-income threshold, the deduction is simple: 20 percent, almost no questions asked, claimed on the one-page Form 8995. The threshold is adjusted for inflation each year, so check the current figures in the form instructions rather than trusting a number from an old article.
Above the threshold, two complications phase in. First, limits based on the W-2 wages your business pays and the property it owns start to cap the deduction, a design that favors businesses with employees or buildings over pure solo operations. Second, the specified service trade or business rules kick in: fields where the main asset is the owner’s skill or reputation, including health, law, accounting, consulting, financial services, athletics, and performing arts, see the deduction shrink and then disappear entirely once income passes the phase-out range. Engineers and architects were specifically carved out and keep the deduction. The IRS FAQ on Section 199A walks through these categories.
What this looks like in real life
A rideshare driver with $30,000 of net profit and modest other income takes roughly a $6,000 deduction on Form 8995, cutting taxable income without spending a dime. A married graphic designer with a healthy six-figure profit may still get the full 20 percent if joint taxable income sits under the threshold. A high-earning consultant, by contrast, may watch the deduction phase down to nothing, because consulting is a specified service business. Same 20 percent headline, three very different outcomes, all driven by income level and business type.
How to make sure you are getting it
If you use tax software, the deduction is usually computed for you, but verify it: look for Form 8995 or 8995-A in your completed return. If you paid a preparer and have pass-through income, ask directly whether QBI was claimed. Landlords should ask about the safe harbor that lets a genuine rental enterprise qualify. And if your income is approaching the threshold, that is the year a session with a tax professional pays for itself, because timing income, retirement contributions, and deductions around the phase-out range can preserve a four-figure tax break. The 20 percent is there for the taking; the only mistake is not checking that you took it.
