How to Calculate and Claim the Section 199A QBI Deduction for a Texas LLC Taxed as an S Corporation in 2026
The Section 199A Qualified Business Income (QBI) deduction can reduce a Texas LLC’s pass-through income by up to 20% on a 2026 federal return, even if the LLC is taxed as an S corporation. Because Texas has no individual income tax, the primary savings is federal—and the S-corp wage structure becomes the key limiter. This article explains how attorneys and tax advisors calculate and claim 199A in 2026 for Texas S-corp LLCs, with examples, limitations, and filing steps.
Section 199A—commonly called the “QBI deduction” or “20% pass-through deduction”—allows eligible owners of pass-through businesses to deduct up to 20% of qualified business income on their individual federal returns. For a Texas LLC that has elected to be taxed as an S corporation, the deduction can be valuable, but it is also uniquely sensitive to how S corporations pay owners: distributions may increase QBI, while W-2 wages may be required to satisfy the wage-and-property limitation once the owner’s taxable income is high enough.
This is a federal income tax deduction claimed at the owner level (Form 1040), not by the LLC/S corporation entity. Texas generally does not impose an individual income tax, but Texas businesses may still face Texas franchise tax and other state/local obligations that do not “mirror” the federal 199A framework. In other words, the 199A deduction is primarily a federal planning and compliance issue for Texas owners.
1) Confirm the Business Structure: Texas LLC Taxed as an S Corporation
A Texas LLC becomes “taxed as an S corporation” by filing an entity classification election (commonly Form 2553 to elect S status, sometimes preceded by Form 8832 depending on the starting classification). Once treated as an S corporation for federal income tax purposes:
Owners who work in the business must receive “reasonable compensation” as W-2 wages for services performed. Those wages are subject to payroll taxes and are deductible by the S corporation as an expense.
Net business profit generally passes through on Schedule K-1 and is typically treated as QBI (subject to exclusions and limitations). Distributions themselves are not QBI; rather, QBI is computed from the business’s qualified items of income, gain, deduction, and loss.
2) What Counts as “Qualified Business Income” (QBI) for an S Corporation?
QBI generally includes the ordinary net income from a qualified trade or business (QTB) conducted in the United States. For an S corporation, QBI is typically the shareholder’s share of the S corporation’s ordinary business income after deductions, as reported on the K-1, with certain adjustments.
Common items that reduce or are excluded from QBI
While the exact computation is fact-specific, attorneys and tax advisors commonly focus on these themes:
W-2 wages paid to an owner are not QBI. In an S corporation, wages are compensation, not pass-through business income. They reduce the entity’s profit (which may reduce QBI) and are taxed as wage income to the owner.
Capital gains and losses are generally excluded. QBI is primarily ordinary business income; net capital gain is a separate limitation in the overall 199A calculation.
Certain investment-type income is excluded. Interest income not properly allocable to the trade or business, dividends, and similar items generally do not qualify.
Guaranteed payments are not an S-corp concept (they apply to partnerships), but the practical takeaway is similar: compensation-like payments to owners are not QBI.
3) The Core 199A Formula in 2026 (Practical Framework)
At a high level, the QBI deduction is the lesser of:
(A) 20% of the owner’s QBI from qualified trades or businesses, plus (if applicable) 20% of qualified REIT dividends and publicly traded partnership income; or
(B) 20% of the owner’s taxable income (computed before the QBI deduction), reduced by net capital gain.
In addition, if the owner’s taxable income is above the applicable threshold amounts for the year, the deduction may be limited by the W-2 wage and qualified property limitation, and for certain “specified service trades or businesses” (SSTBs), it may be phased out.
Important: The threshold amounts and phase-in ranges are inflation-adjusted annually. For 2026, you must use the IRS-published thresholds for that tax year when performing the final calculation.
4) The W-2 Wage and Qualified Property Limitation (Why S-Corp Payroll Matters)
Once a taxpayer’s taxable income exceeds the annual threshold, the 199A deduction tied to a particular trade or business is limited to the greater of:
1) 50% of W-2 wages paid by the business, or
2) 25% of W-2 wages + 2.5% of the unadjusted basis immediately after acquisition (UBIA) of qualified property.
For many Texas professional practices and service companies organized as S corporations, the business may not hold much “qualified property” (e.g., limited depreciable tangible assets). That often makes the W-2 wage component the decisive limiter.
Planning tension: “More distributions” vs. “Enough wages”
S corporation owners often prefer distributions over wages to reduce payroll taxes. Section 199A introduces a competing consideration: if taxable income is high enough, insufficient W-2 wages can cap the QBI deduction. The result is not that you should underpay wages; rather, you should set wages at a defensible reasonable compensation level and then model whether the wage limitation will reduce the expected 199A benefit.
5) SSTB Rules: When the 199A Deduction Can Phase Out
Many attorney-owned businesses should pay close attention to SSTB classification. An SSTB includes certain service businesses where the principal asset is the reputation or skill of employees/owners, including law, accounting, consulting, health, and other enumerated fields.
If the Texas LLC taxed as an S corporation operates as an SSTB, then once the owner’s taxable income exceeds the threshold, the 199A deduction may be partially reduced and then potentially eliminated after the phase-out range, depending on the year’s indexed thresholds.
If the business is not an SSTB, the wage/property limitation still applies above the threshold, but the deduction is not categorically phased out in the same manner.
Practice note: SSTB determination can be nuanced for mixed-activity businesses (e.g., a firm with both legal services and separate productized/non-service revenue). Documentation, entity separations, and operational reality matter, and “cracking” strategies are closely scrutinized.
6) Step-by-Step: How to Calculate the 199A Deduction for a Texas S-Corp LLC
Step 1: Gather the right documents
For each owner, you typically need:
Form 1120-S and the owner’s Schedule K-1
W-2 wage detail for the business (including timely filed W-2s)
Qualified property records (asset schedules supporting UBIA, if relevant)
The owner’s draft Form 1040 taxable income calculation (because thresholds and overall limitations are owner-specific)
Step 2: Compute QBI for each qualified trade or business
Start with the K-1 items attributable to the trade or business and adjust for excluded items. Confirm whether there are multiple trades or businesses that must be analyzed separately or can be aggregated under the regulations (aggregation has strict requirements and must be consistently applied and disclosed).
Step 3: Determine if the owner is above the 2026 threshold
The owner’s taxable income (before the QBI deduction) determines whether the wage/property limitation applies and whether an SSTB faces phase-out. Because the thresholds are inflation-adjusted, use the IRS figures for 2026, and evaluate filing status (married filing jointly vs. single, etc.).
Step 4: Apply the wage/property limitation if required
If above the threshold, compute the limit:
50% of W-2 wages; and
25% of W-2 wages + 2.5% of UBIA of qualified property.
Use the greater of the two as the maximum allowable 199A amount for that trade or business (after considering any SSTB phase-in/phase-out adjustments where applicable).
Step 5: Apply the overall taxable income limitation
Even if the business-based computation yields a large deduction, the final deduction cannot exceed 20% of taxable income minus net capital gain.
Step 6: Claim the deduction on the correct form (Form 8995 or 8995-A)
Taxpayers generally use Form 8995 (simplified) if they meet eligibility criteria; otherwise, they use Form 8995-A with additional schedules (including wage/property details and aggregation statements where applicable). Many higher-income S-corp owners end up on the more detailed form due to the limitation mechanics.
7) Example 1: Non-SSTB Texas S-Corp LLC With Enough W-2 Wages
Facts (simplified): A Texas LLC taxed as an S corporation operates a non-SSTB logistics business. In 2026, the owner’s share of ordinary business income is $400,000. The S corporation pays $200,000 of W-2 wages (including wages to employees and the owner). The business has minimal qualified property. Assume the owner is above the threshold so the wage limitation applies.
Compute 20% of QBI: 20% × $400,000 =
