QBI Deduction

The QBI deduction, or qualified business income deduction, is the federal income tax deduction under section 199A of the Internal Revenue Code that lets a taxpayer other than a corporation deduct up to 20 percent of the qualified business income of each qualified trade or business the taxpayer carries on, a term that excludes a specified service trade or business and the trade or business of performing services as an employee (26 U.S.C. 199A(d)(1)), plus 20 percent of qualified real estate investment trust dividends and qualified publicly traded partnership income. The owner claims it on a personal return, and the business itself never takes it. The total is capped at 20 percent of taxable income reduced by net capital gain, and above a taxable income threshold each business is limited again by the wages it pays and the property it holds.

What Qualified Business Income Is

Qualified business income is a statutory measure of one business’s operating result, and it is assembled item by item rather than lifted off a set of books. The term means, for any taxable year, the net amount of qualified items of income, gain, deduction, and loss with respect to any qualified trade or business of the taxpayer, and it does not include any qualified REIT dividends or qualified publicly traded partnership income (26 U.S.C. 199A(c)(1)).

Two conditions make an item qualified. Qualified items of income, gain, deduction, and loss are items to the extent they are effectively connected with the conduct of a trade or business within the United States, within the meaning of section 864(c) as modified for this purpose, and included or allowed in determining taxable income for the taxable year (26 U.S.C. 199A(c)(3)(A)). Both tests run item by item, so one business can hold items that qualify alongside items that do not.

The exclusions are then listed one at a time, and these are the ones an operating business runs into. Out go items of short-term or long-term capital gain and loss, any dividend or income equivalent to a dividend, any interest income other than interest properly allocable to a trade or business, commodities and foreign currency items, amounts received from an annuity not received in connection with the trade or business, and any deduction or loss allocable to one of those excluded amounts (26 U.S.C. 199A(c)(3)(B)).

Owner pay is removed by a rule of its own. The reasonable-compensation exclusion, and what it costs an S corporation shareholder who has to run salary through payroll, is set out in c corp vs s corp. The same rule also removes any guaranteed payment described in section 707(c) paid to a partner for services rendered with respect to the trade or business (26 U.S.C. 199A(c)(4)(B)).

Some of the items that belong in the figure sit on the owner’s return rather than the business’s ledger. To work out the total amount of QBI you must consider all items attributable to the trade or business, including unreimbursed partnership expenses, business interest expense, the deductible part of self-employment tax, the self-employment health insurance deduction, and contributions to qualified retirement plans (IRS, Instructions for Form 8995).

How the Deduction Is Computed

The section fixes one overall amount as the lesser of two numbers. In the case of a taxpayer other than a corporation, and except as provided in subsection (i), there is allowed a deduction for any taxable year equal to the lesser of the combined qualified business income amount of the taxpayer, or 20 percent of the excess of taxable income for the taxable year over net capital gain for that year (26 U.S.C. 199A(a)).

The first of those two numbers is itself a sum. The combined qualified business income amount means the sum of the amounts determined for each qualified trade or business carried on by the taxpayer, plus 20 percent of the aggregate qualified REIT dividends and qualified publicly traded partnership income for the taxable year (26 U.S.C. 199A(b)(1)).

Taxable income in that formula is not the number at the bottom of the return. For this purpose it is computed without regard to section 68 and without regard to any deduction allowable under section 199A itself (26 U.S.C. 199A(e)(1)).

For a taxable year beginning after December 31, 2025, subsection (i) sets a floor under that result. An applicable taxpayer, meaning one whose aggregate qualified business income from all active qualified trades or businesses is at least $1,000, deducts the greater of the amount determined without regard to that subsection or $400, and both dollar amounts are increased for inflation for a taxable year beginning after 2026 (26 U.S.C. 199A(i)). How that floor reads against the corporate side is in c corp vs s corp.

Material participation matters in one place here and not in the other. Material participation under section 469 is not required to qualify for the QBI deduction (IRS, Instructions for Form 8995). It is required for that floor, which reaches only a trade or business in which the taxpayer materially participates within the meaning of section 469(h) (26 U.S.C. 199A(i)(2)(B)).

The W-2 Wage and Property Limitation

Above the threshold amount, a business’s share of the deduction stops being a flat percentage of its income and starts depending on what it pays in wages and what it owns. The amount determined for any qualified trade or business is the lesser of 20 percent of the taxpayer’s qualified business income with respect to that trade or business, or the greater of 50 percent of the W-2 wages with respect to that trade or business, or the sum of 25 percent of those W-2 wages plus 2.5 percent of the unadjusted basis immediately after acquisition of all qualified property (26 U.S.C. 199A(b)(2)).

W-2 wages means the amounts described in paragraphs (3) and (8) of section 6051(a) paid by the person for employment of employees during the calendar year ending during the taxable year, and the term excludes any amount not properly allocable to qualified business income and any amount not properly included in a return filed with the Social Security Administration on or before the 60th day after that return’s due date, extensions included (26 U.S.C. 199A(b)(4)).

Qualified property means tangible property of a character subject to the allowance for depreciation under section 167 that is held by, and available for use in, the qualified trade or business at the close of the taxable year, is used at any point during the year in the production of qualified business income, and whose depreciable period has not ended before the close of the year (26 U.S.C. 199A(b)(6)).

The limitation does not reach every owner. Where a taxpayer’s taxable income for the taxable year does not exceed the threshold amount, the per-business computation is applied without regard to the wage and property limit (26 U.S.C. 199A(b)(3)(A)). Between the threshold amount and the threshold amount plus $75,000, or $150,000 on a joint return, the limit phases in (26 U.S.C. 199A(b)(3)(B)).

Those two phase-in figures are current, and they are also new. They apply to taxable years beginning after December 31, 2025, and they replaced $50,000, or $100,000 on a joint return (26 U.S.C. 199A, Amendments and Effective Date of 2025 Amendment). A return for an earlier year runs on the older pair.

The Specified Service Trade or Business Carve-Out

The carve-out takes a whole class of business out of the section before any limit gets computed. A qualified trade or business means any trade or business other than a specified service trade or business or the trade or business of performing services as an employee (26 U.S.C. 199A(d)(1)).

A specified service trade or business is one described in section 1202(e)(3)(A), applied without regard to the words “engineering, architecture,” or one that would be so described if the term “employees or owners” were substituted for “employees”, and the definition also picks up a business performing services that consist of investing and investment management, trading, or dealing in securities, partnership interests, or commodities (26 U.S.C. 199A(d)(2)).

The section 1202 list names accounting outright. It covers any trade or business involving the performance of services in the fields of health, law, engineering, architecture, 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 1 or more of its employees (26 U.S.C. 1202(e)(3)(A)).

For a CPA firm the consequence is direct. Accounting stays on the list after those two words are struck out, so an accounting practice is itself a specified service trade or business (26 U.S.C. 199A(d)(2)(A)).

Income keeps the carve-out from being absolute at the bottom of the scale. Where a taxpayer’s taxable income for the year is less than the sum of the threshold amount plus $75,000, or $150,000 on a joint return, a specified service trade or business does not fail to be treated as a qualified trade or business on that ground, and only the applicable percentage of its qualified items, its W-2 wages and its qualified property is taken into account (26 U.S.C. 199A(d)(3)). That pair was raised by the same 2025 amendment that moved the wage and property phase-in range, so a return for a year beginning before 2026 runs on $50,000, or $100,000 on a joint return (26 U.S.C. 199A, Amendments and Effective Date of 2025 Amendment).

The threshold amount both rules turn on is $157,500, or 200 percent of that amount on a joint return, increased for inflation for any taxable year beginning after 2018 (26 U.S.C. 199A(e)(2)).

Which Form Carries It

Individuals and eligible estates and trusts that have QBI use Form 8995 to figure the deduction if they have QBI, qualified REIT dividends, or qualified PTP income or loss, if their taxable income before the QBI deduction is at or below the year’s stated limit, and if they are not a patron in a specified agricultural or horticultural cooperative; otherwise they use Form 8995-A (IRS, Instructions for Form 8995).

The limit that routes the return is stated for the filing year. For 2025 it is taxable income before the QBI deduction of $394,600 for married filing jointly and $197,300 for all other returns (IRS, Instructions for Form 8995).

The longer form exists because it carries the schedules the simplified one has no room for. Form 8995-A takes Schedule A for specified service trades or businesses, Schedule B for aggregation of business operations, Schedule C for loss netting and carryforward, and Schedule D for special rules for patrons of agricultural or horticultural cooperatives (IRS, Instructions for Form 8995-A).

The result then lands on the owner’s own return rather than inside the business’s numbers. Form 8995 line 15 is entered on Form 1040, 1040-SR or Form 1040-NR, line 13a, on Form 1041, line 20, and on Form 990-T, line 9 (IRS, Instructions for Form 8995).

The entity that earned the income does not claim anything. S corporations and partnerships are not eligible for the deduction, and instead must pass through to their shareholders or partners the necessary information on an attachment to Schedule K-1 (IRS, Instructions for Form 8995). The statute says the same thing in one clause: in the case of a partnership or S corporation, section 199A is applied at the partner or shareholder level (26 U.S.C. 199A(f)(1)(A)).

A Worked Example

Say a sole proprietor runs a landscaping business with no employees and no depreciable property, has taxable income before the deduction that sits under the threshold amount for the year, and holds no REIT dividends or publicly traded partnership interests. Because taxable income is under the threshold, the wage and property limit does not apply, and having no payroll costs this owner nothing.

Qualified business income                       120,000
Taxable income before the deduction             150,000
Net capital gain                                      0

Combined QBI amount, 20% of 120,000              24,000
20% of taxable income less net capital gain      30,000

Deduction, the lesser of the two                 24,000

Push taxable income past the threshold amount on the same facts and the deduction starts to shrink. With no W-2 wages and no qualified property the greater-of amount in the per-business computation is zero, so inside the phase-in range 20 percent of qualified business income is cut back in proportion to how far taxable income exceeds the threshold, and once taxable income exceeds the threshold plus $75,000, or $150,000 on a joint return, the amount determined for that business is zero (26 U.S.C. 199A(b)(3)(B)).

What the QBI Deduction Is Not

It Is Not the Business’s Book Net Income

Qualified business income is built only from qualified items, so capital gains, dividends, interest not allocable to the business and owner compensation are all gone before the figure exists, and the Form 8995 instructions then require items that sit on the owner’s own return, such as the deductible part of self-employment tax, the self-employment health insurance deduction and contributions to qualified retirement plans, to be considered as well. Book net income and taxable income already part company for their own reasons, and that split is set out in net income.

It Is Not a Business Expense

It is not allowable in arriving at adjusted gross income, and it is not an itemized deduction either. For an individual who does not elect to itemize, taxable income means adjusted gross income minus a list of items that includes the standard deduction and any deduction provided in section 199A (26 U.S.C. 63(b)). Itemized deductions are the deductions allowable under the chapter other than those allowable in arriving at adjusted gross income and any deduction referred to in any paragraph of subsection (b), which is where section 199A sits (26 U.S.C. 63(d)). The owner therefore gets it whether the return itemizes or takes the standard deduction.

It Does Not Reduce Self-Employment Tax

The deduction is allowed only for purposes of chapter 1 of the Internal Revenue Code, the chapter section 199A sits in (26 U.S.C. 199A(f)(3)). Self-employment tax is imposed by section 1401, which sits in chapter 2 (26 U.S.C. 1401), and the rates it runs at are set out in federal income tax liability. A larger QBI deduction leaves the self-employment tax line untouched.
