The qualified business income deduction, explained
A deduction for business owners that costs nothing to claim and is easy to misread. What income qualifies, which form you use, and what it does not reduce.
Quick answers
- What is the qualified business income deduction?
- It takes a share of the qualifying profit of a pass-through business off your income before tax is figured. Sole proprietors, partners, S corporation shareholders and many rental owners can claim it, and nothing has to be spent to get it.
- Do I have to itemize to claim the QBI deduction?
- No. It sits outside the standard-versus-itemized choice, so you can take the standard deduction and this one together. An owner who took the standard deduction and did not see this on the return should have it checked.
- Does the QBI deduction reduce self-employment tax?
- No. It reduces taxable income only. Self-employment tax is figured on Schedule SE from the business profit before any of this happens, and the deduction does not lower adjusted gross income either.
If you run a business that is not a C corporation, a share of its profit comes off your income before tax is figured. You do not have to spend anything to get it, and for most owners it is computed on a single-page form.
| Qualified business income deduction rate | 20% | 2025 Form 8995 |
|---|---|---|
| Taxable income limit for the simplified QBI form, single/HOH | $197,300 | 2025 Instructions for Form 8995 |
| Taxable income limit for the simplified QBI form, married filing jointly | $394,600 | 2025 Instructions for Form 8995 |
What it is
The qualified business income deduction takes 20% off the qualifying profit of a pass-through business. That covers a sole proprietor filing Schedule C, a partner receiving a K-1 from a partnership, a shareholder in an S corporation, and most owners of rental real estate that rises to the level of a trade or business.
The deduction does not come from a business account or a receipt. It is a calculation applied to figures already on the return, so nothing has to be spent to claim it — but it is not simply the rate times the bottom line of your Schedule C, because several adjustments come out of that profit first.
Which form
If your taxable income before this deduction is at or below $197,300, or $394,600 on a joint return, you use Form 8995, the simplified computation. It is one page: list each business and its qualified income, combine, and apply the rate.
Above those levels the calculation moves to Form 8995-A and grows two sets of limits. The deduction becomes capped by a measure of the W-2 wages the business paid and the cost of the property it holds, which is why an owner-operator with no employees can lose most of it at higher income. And a specified service trade or business — the group that includes health, law, accounting, consulting, athletics, financial services and any business whose principal asset is the reputation or skill of its owners — begins to phase out of the deduction entirely over a band above the threshold. Both of those turn on figures beyond the scope of this article; if your income is near the ceiling, the difference between the two forms is worth planning for before December rather than discovering in April.
What counts as qualified business income
Qualified business income is the net profit of a US trade or business. What it is not is the more useful list:
- Wages you pay yourself. An S corporation owner's own W-2 salary is not qualified business income, even though it came out of the same business. Reasonable compensation therefore reduces the deduction while it reduces payroll exposure, which is one of the trade-offs in the S corporation decision.
- Investment income. Interest not tied to the business, dividends, capital gains and losses, and most foreign currency and commodity items are excluded.
- Guaranteed payments to a partner for services.
- Income earned outside the United States, and income from a business conducted as an employee.
- The deductions the business profit already funds. For a sole proprietor, qualified business income is Schedule C net profit reduced by the deductible half of self-employment tax, the self-employed health insurance deduction, and self-employed retirement contributions, to the extent each is attributable to that business. Those three come off before the rate is applied, so the deduction is always smaller than the rate times the profit line.
Qualified REIT dividends and publicly traded partnership income get their own component on the same form, computed at the same rate.
What it reduces, and what it does not
The deduction reduces taxable income. It does not reduce self-employment tax, which is figured on Schedule SE from the business profit before any of this happens, and it does not reduce adjusted gross income, so it does not help with anything keyed to AGI — a phase-out, a state return that starts from federal AGI, or an income-driven student loan calculation.
It is also subject to an overall limit: the deduction cannot exceed 20% of your taxable income after subtracting net capital gain. In a year when a business profit is offset by other deductions, that ceiling can be what actually sets the number.
You do not have to itemize
This is a below-the-line deduction that sits outside the standard-versus-itemized choice. You take the standard deduction and this one, or itemize and take this one; nothing about it depends on which side you land on. An owner who took the standard deduction and did not see this on the return should have it checked.
A loss carries. If the business loses money, there is no deduction for the year and the negative amount carries forward to reduce qualified business income in the next one.
