The qualified business income (QBI) deduction is a tax concept that allows many small business owners to deduct up to 20% of their business profits directly from their federal taxable income. The deductionâoften called the 199A deductionâwas originally created under the Tax Cuts and Jobs Act of 2017. The deduction was made permanent under the 2025 One Big Beautiful Bill Act (OBBBA).
QBI generally includes the ordinary income your business generates after expenses, including unreimbursed partnership expenses, business interest expense, self-employment health insurance deduction, contributions to qualified retirement plans, and the deductible portion of self-employment tax. It applies to income from sole proprietorships, partnerships, LLCs treated as partnerships, and S corporationsâthe same business types whose income âpasses throughâ to their ownersâ Form 1040. If youâre a sole proprietor who runs income and expenses through Schedule C, reports partnership income on a Form K-1, or owns shares in an S corporation, your share of profits may qualify.
QBI does not include wage income such as on a W-2, capital gains, dividends, interest not related to the business, commodities transactions, or income from C corporations. It also excludes reasonable compensation paid to S corporation shareholders and guaranteed payments to partners.
The QBI deduction is available for several business structure typesâsole proprietorships, LLCs, S corporations, and partnershipsâas well as certain trusts and estates. Want to learn more? Read Britannica Moneyâs guide to business structure types.
The QBI deduction is available only to taxpayers with qualified pass-through income, which is why C corporations and their shareholders do not qualify. The deduction is phased out at the income ranges noted below. Income levels in the phaseout range require use of Form 8995A to calculate the QBI deduction; most other businesses may use Form 8995.
âSpecified service trades or businesses,â or âSSTBsâ include professionals in law, accounting, consulting, medicine, performing arts, athletics and financial services. These businesses may take a full QBI deduction if their incomes are below the thresholds, but require completion of a special Schedule A of Form 8995A to calculate their phaseout.
| Filing status | Taxable income threshold (full 20% deduction allowed up to âŠ) | Phaseout / limitation range |
|---|---|---|
| Single/head of household/married filing separately | $197,300 | $197,301 â $247,300 |
| Married filing jointly | $394,600 | $394,601 â $494,600 |
The deduction is calculated using Form 8995 (or Form 8995-A for more complex situations, or if your income is in the phaseout range). In the most common scenario, the math is straightforward:
The QBI deduction also allows taxpayers to deduct up to 20% of qualified dividends from real estate investment trusts (REITs), even though this income isnât part of a pass-through business. These dividends are handled separately on the QBI forms and arenât subject to the business structure rules.
There is one important guardrail: The deduction cannot exceed 20% of taxable income minus net capital gains. In other words, even if your QBI is large, your overall taxable income sets the ceiling.
Because the deduction is taken at the owner level, not the business level, each owner (e.g., each partner in a partnership) calculates their own deduction separately on their individual tax return.
The QBI deduction effectively lowers the tax rate on eligible business income. For example, if youâre a sole proprietor with $100,000 in qualified business income, you may be able to deduct up to $20,000 from your taxable income, reducing the amount subject to federal income tax. For many small business owners, this deduction provides meaningful tax relief without requiring a change to the business structure.
The QBI deduction remains a valuable benefit for millions of U.S. business owners. Understanding whether your business structure qualifiesâand how the deduction fits into your broader tax pictureâcan help you keep more of what your business earns.
