The 199A deduction is an owner-level deduction for qualified business income

The 199A deduction, also called the qualified business income or QBI deduction, is a federal deduction for eligible taxpayers other than corporations. It commonly affects owners who report self-employed business income directly or receive business items through a partnership or S corporation.

The deduction does not change the business’s gross receipts or operating expenses. It is calculated at the owner level after qualified income, deductions, and losses flow through the federal tax system.

Twenty percent is a ceiling, not an automatic result

The basic QBI component begins with 20% of qualified business income from each qualified trade or business. A separate component can include 20% of qualified real estate investment trust dividends and qualified publicly traded partnership income.

The combined amount is then limited to 20% of taxable income after subtracting net capital gain. Wage and property limits, specified service rules, loss carryforwards, and cooperative adjustments can reduce the result further.

A simplified example shows the taxable-income ceiling. If a business produces $80,000 of positive QBI, the initial 20% amount is $16,000. If 20% of taxable income minus net capital gain is only $12,000, the overall deduction cannot exceed $12,000 before considering any other applicable rule.

Qualified business income is a net tax concept

QBI generally means the net amount of qualified income, gain, deduction, and loss connected with a qualified U.S. trade or business. It is not simply the amount shown as revenue on an invoice or deposited into a business bank account.

Business deductions that are properly allocable to the trade or business can reduce QBI. IRS instructions identify examples that may include the deductible part of self-employment tax, the self-employed health insurance deduction, and deductible retirement-plan contributions when those items are allocable to the business.

Several familiar items are excluded. Employee wages, capital gains and losses, nonbusiness interest, S-corporation reasonable compensation, and partnership guaranteed payments for services are not QBI. Qualified REIT dividends and qualified PTP income also sit outside QBI itself because Section 199A calculates them through a separate component.

Business form determines how the deduction reaches the owner

A sole proprietor calculates QBI from the owner’s qualified business items. Partnerships and S corporations generally identify Section 199A items at the entity level and report each owner’s share, but the partner or shareholder applies personal taxable-income limits on the individual return.

A C corporation cannot claim the owner-level QBI deduction, and its earnings do not become QBI merely because a shareholder owns the corporation. Compensation for services as an employee is also excluded, even when the employee works for a closely held business.

The distinction prevents the deduction from treating salary as passthrough profit. Federal regulations also contain a presumption addressing a person who stops being treated as an employee and then provides substantially the same services to the former employer.

2026 thresholds determine when additional limits matter

For a tax year beginning in 2026, the Section 199A threshold is $403,500 for married individuals filing jointly, $201,775 for married individuals filing separately, and $201,750 for all other returns. The relevant measure is taxable income computed before the QBI deduction, not QBI alone.

The upper end of the 2026 phase-in range is $553,500 for joint returns, $276,775 for married filing separately, and $276,750 for all other returns. The $150,000 joint range and $75,000 nonjoint range gradually introduce restrictions rather than switching every limitation on at the first dollar above the threshold.

These amounts are indexed, so a threshold from an older return or article should not be reused for 2026. The filing status on the federal return also controls which threshold applies.

W-2 wages and qualified property can cap higher-income QBI

Above the threshold range, the QBI amount for a business generally cannot exceed the greater of two measures: 50% of the business’s allocable W-2 wages, or 25% of those wages plus 2.5% of the unadjusted basis immediately after acquisition of qualified property. UBIA is a tax measure of qualifying depreciable property before depreciation adjustments, not the property’s current market value.

This limitation can matter for a business with substantial profit but few employees and little qualifying property. It applies business by business unless valid aggregation rules allow multiple businesses to be treated together.

Aggregation has ownership, tax-year, operational, and reporting requirements. It is not simply a choice to combine whichever businesses produce the largest deduction.

Specified service businesses receive income-dependent treatment

A specified service trade or business, often shortened to SSTB, includes listed service fields such as health, law, accounting, consulting, financial services, brokerage services, investing, investment management, trading, and dealing in securities or commodities. Engineering and architecture are excluded from the statutory SSTB list.

At or below the threshold, SSTB income can be treated as qualified business income if the other requirements are met. Within the phase-in range, only an applicable percentage of the SSTB’s QBI, wages, and qualified-property basis enters the calculation. Above the upper end of the range, SSTB items are excluded from the QBI component.

The SSTB analysis concerns the nature of the business’s services and the owner’s taxable income. A professional title by itself may not capture every activity performed by a mixed or related business.

Active business income has a new minimum deduction in 2026

Section 199A became permanent under amendments enacted in 2025. For tax years beginning in 2026, it also provides a $400 minimum deduction for an applicable taxpayer with at least $1,000 of aggregate QBI from active qualified trades or businesses.

An active qualified trade or business is one in which the taxpayer materially participates under Section 469. The minimum rule therefore does not turn every passive ownership interest or investment return into a $400 deduction.

The statute compares the normally calculated deduction with $400 and allows the greater amount for an applicable taxpayer. Both the $400 and $1,000 figures are scheduled for inflation adjustments in tax years beginning after 2026.

Losses can affect more than one tax year

When the net QBI from qualified trades or businesses is negative, Section 199A treats that amount as a qualified business loss in the succeeding tax year. The carryforward offsets later positive QBI for purposes of the deduction.

This QBI loss rule is separate from whether a business loss is currently deductible under basis, at-risk, passive-activity, or excess-business-loss rules. Those provisions can affect when an item enters the Section 199A calculation.

Rental real estate does not qualify automatically

A rental real estate activity may qualify when it constitutes a trade or business under federal standards. Revenue Procedure 2019-38 also provides a safe harbor under which a qualifying rental real estate enterprise is treated as a trade or business solely for Section 199A.

Failure to satisfy the safe harbor does not automatically disqualify a rental. The activity may still qualify if it otherwise rises to the level of a trade or business, and special rules can apply to property rented to a commonly controlled operating business.

Form 8995 and Form 8995-A serve different computations

Form 8995 is the simplified QBI computation. Form 8995-A and its schedules handle calculations involving matters such as higher taxable income, wage and property limits, SSTBs, loss netting, and aggregation.

Passthrough owners depend on the Section 199A information supplied by the entity, but the reported numbers are inputs rather than a guaranteed deduction. The owner’s other qualified businesses, carryforwards, taxable income, net capital gain, and filing status can change the final amount.
