Section 199A QBI Deduction: Who Qualifies and Income Thresholds

The Section 199A QBI deduction lets owners of pass-through businesses deduct up to 20% of their qualified business income from their taxable income.¹ It was originally scheduled to sunset after 2025, but the One Big Beautiful Bill Act, signed on July 4, 2025, made it permanent.² The deduction reduces taxable income rather than adjusted gross income, and how much you can actually claim turns on three things: your total income, the type of business you run, and how much that business pays in wages or holds in qualifying property.

Who Can Claim the Deduction

Any taxpayer other than a C corporation can potentially claim it. The typical claimants are sole proprietors, partners in partnerships, S corporation shareholders, and members of LLCs taxed as pass-throughs.³ Certain trusts and estates that generate business income can also qualify. What ties them together is that the business itself pays no federal income tax; profit flows to the owner’s personal return, and the deduction is worked out at that individual level.

What Counts as Qualified Business Income

QBI is the net profit from a qualified trade or business after ordinary deductions. The income has to be effectively connected with a business conducted inside the United States and has to appear in your taxable income for the year.¹ Only ordinary business income qualifies.

Several categories are deliberately left out. Capital gains and losses, both short-term and long-term, do not count. Neither do most dividends, most interest income unless directly tied to the business, annuity payments unrelated to the business, or income from commodity or foreign currency transactions.¹ Income earned outside the United States is excluded as well.

Payments to owners for their own labor are also stripped out, because the deduction targets business profit rather than compensation. Reasonable compensation an S corporation pays a shareholder does not count as QBI, and guaranteed payments to partners for services are treated the same way.³ The IRS watches this line closely; an S corporation owner who takes an unreasonably low salary to inflate QBI invites scrutiny.

Qualified REIT dividends and qualified publicly traded partnership income are handled on a separate track but still get a 20% deduction, and this REIT/PTP component is not subject to the wage and property limits that apply to ordinary QBI.³ Your final Section 199A deduction combines both pieces, and the total cannot exceed 20% of your taxable income minus net capital gain.¹

If your total QBI for the year is negative, whether from one business’s loss or from losses across several outrunning the gains, you get no deduction that year. The negative amount carries forward indefinitely and reduces future QBI until absorbed.¹

The Income Thresholds That Change Everything

Your taxable income decides whether you claim the full 20% or run into extra limits. For 2026, the threshold is $201,750 for single filers and $403,500 for joint filers. If your taxable income before the QBI deduction sits at or below those numbers, you can generally take the full deduction without worrying about wage or property tests.⁴

Cross the threshold and a phase-in range begins, where the wage and property limits gradually take hold. The One Big Beautiful Bill Act widened those ranges starting in 2026. The range is now $75,000 for single filers and $150,000 for joint filers, up from $50,000 and $100,000.² The limits reach full force at $276,750 for single filers and $553,500 for joint filers. Within that band, the deduction is scaled back proportionally as income climbs. Both thresholds are indexed to inflation.

The Wage and Property Caps

Once you are above the threshold or inside the phase-in range, the deduction for each business is capped at the greater of two figures:⁵

50% of the W-2 wages the business paid during the year, or
25% of W-2 wages plus 2.5% of the unadjusted basis immediately after acquisition (UBIA) of qualified property.

Your per-business deduction is then the lesser of 20% of QBI or whichever of those two figures is larger. The second formula exists so capital-intensive businesses with few employees but heavy equipment or building investment can still generate a meaningful deduction. A small-payroll manufacturer with millions in factory equipment can lean on the property component.

Qualified property means tangible, depreciable assets used in the business. Land and inventory are out. The asset has to still be within its depreciable period or within ten years of being placed in service, whichever is longer. The basis figure is the original cost before depreciation.¹

W-2 wages must be properly reported and include elective deferrals and deferred compensation. Only wages allocable to QBI count, so wages tied to activities that do not generate qualified income are stripped from the calculation.

Service Businesses Face Extra Rules

The code treats certain service professions differently. A specified service trade or business (SSTB) faces additional restrictions that can shrink or wipe out the deduction for higher-income owners. The listed fields are health care, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage, investment management, and trading.⁶ A separate catch-all covers businesses whose main value comes from an individual’s reputation or skill, defined narrowly to mean endorsement income, licensing of a person’s name or likeness, and appearance fees.

The SSTB label only matters if your income enters the phase-in range. Below the threshold, an SSTB owner claims the same deduction as anyone else. Inside the phase-in range, the deduction is reduced proportionally. Above the top of the range ($276,750 single, $553,500 joint for 2026), the deduction disappears entirely for SSTB income. That creates a cliff that high-earning service professionals need to plan around.

Engineering and architecture are explicitly excluded from the SSTB definition.⁶ An engineer or architect over the phase-in range still qualifies, subject only to the standard wage and property caps.

A business that mixes some SSTB work with other activities does not automatically get the SSTB label. If gross receipts are $25 million or less and under 10% come from SSTB activities, the whole business avoids the label. Above $25 million in gross receipts, the cutoff drops to 5%.⁶ Cross those percentages and the entire business, not just the service portion, becomes an SSTB.

Rental Real Estate

Rental income qualifies only if the activity rises to the level of a trade or business. Passive triple-net leases where the tenant handles everything generally do not qualify. For more active landlords, the IRS offers a safe harbor: perform at least 250 hours of rental services per year and keep detailed records, and the activity is treated as a trade or business for QBI purposes.⁷

Rental services include advertising units, screening tenants, collecting rent, handling maintenance and repairs, and managing the property. Arranging financing, reviewing financial statements, and traveling to and from the property do not count toward the 250 hours.⁷ For rental enterprises that have existed at least four years, the 250-hour test only has to be met in three of the last five tax years. Contemporaneous logs showing who did the work, what they did, and when are required.

Combining Multiple Businesses

If you own more than one business, the wage and property math runs separately for each. That hurts when one business has strong QBI but pays no wages and owns no qualifying property, while another has heavy payroll but thin margins. Aggregation lets you combine their wages, property, and income into a single calculation.⁸

Aggregation requires common ownership and operational connections. Once elected, you have to stick with it in future years absent a significant change in circumstances. A disclosure statement identifying each aggregated business, including name, EIN, and a description of its activities, must be attached to the return. Skip that statement and the IRS can disaggregate the businesses, freezing you out of the election for three years.⁸

How to File

Which form you use depends on your income. If your taxable income before the QBI deduction is at or below $201,750 ($403,500 for joint filers) and you are not a patron of an agricultural or horticultural cooperative, use Form 8995, the simplified version. Above those thresholds, or if you are a cooperative patron, use Form 8995-A, which walks through the wage limits, property math, and SSTB phase-outs.⁹

Either way, keep clean records that separate QBI from other income. S corporations and partnerships report QBI information to owners on Schedule K-1, but the individual taxpayer is on the hook for the final calculation. If you aggregate, remember the disclosure statement. The deduction lands on Form 1040 and reduces taxable income without touching your adjusted gross income or the deductions that depend on AGI.
