The One Big Beautiful Bill Act made one of the most valuable tax provisions for business owners permanent: the Section 199A qualified business income deduction, which allows owners of pass-through entities to deduct up to 20% of their qualified business income from their taxable income. For a business owner with $500,000 in qualifying income, that is a potential $100,000 deduction worth $37,000 to $50,000 in actual tax savings depending on state.
Yet AE Tax Advisors, a boutique Montana-based tax advisory firm, finds that the majority of eligible business owners are either unaware of the deduction, underutilizing it due to avoidable limitations, or failing to structure their entities to maximize it. The deduction is permanent. The planning opportunity is immediate. And the difference between an optimized and unoptimized Section 199A calculation can exceed $50,000 per year for high-income business owners.
About AE Tax Advisors
AE Tax Advisors works exclusively with business owners earning $500,000 or more annually. The firm’s Section 199A optimization work is a standard component of every client engagement because the deduction interacts with entity structure, compensation, property holdings, and retirement planning in ways that require coordinated modeling. The firm recalculates the optimal configuration annually as client circumstances change.
The Limitations That Kill the Deduction for High Earners
Section 199A allows individuals, trusts, and estates to deduct up to 20% of qualified business income earned through pass-through entities. The deduction effectively lowers the top rate on qualifying income from 37% to approximately 29.6%. However, for business owners earning above $191,950 (single) or $383,900 (married filing jointly) in 2026, the deduction is limited to the greater of 50% of W-2 wages paid by the business, or 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property.
Without sufficient W-2 wages or qualified property, the deduction is reduced or eliminated entirely. This is where most business owners lose the benefit. The S-Corp structure naturally generates W-2 wages because the owner is required to pay themselves a reasonable salary. AE Tax Advisors calibrates this salary to minimize self-employment tax while generating enough wages to satisfy the Section 199A limitation. For sole proprietors with no employees, the business generates zero W-2 wages and the deduction can be completely eliminated above the threshold. AE Tax Advisors frequently converts these entities to S-Corp status specifically to unlock the QBI deduction, and the combined benefit routinely exceeds $40,000 annually. The conversion from sole proprietor to S-Corp for QBI purposes is one of the most common and highest-impact recommendations AE Tax Advisors makes, and it is often the single change that produces the largest first-year savings for new clients who have been operating in the default entity structure.
The Qualified Property Alternative for Capital-Intensive Businesses
For businesses that hold significant real estate, equipment, or machinery, the 2.5% of unadjusted basis calculation can satisfy the limitation even without substantial W-2 wages. The key term is “unadjusted basis immediately after acquisition,” meaning the original cost, not the depreciated basis. Even fully depreciated equipment continues to support the Section 199A calculation based on its original purchase price.
AE Tax Advisors identifies every qualifying asset across a client’s entities and ensures they are properly included in the computation. The firm has found that many CPAs overlook qualifying property or calculate the unadjusted basis incorrectly, leaving significant deductions unclaimed. For clients in manufacturing, construction, agriculture, and other capital-intensive industries, the qualified property component often provides a larger deduction than the wage component alone.
Aggregation, Separation, and Service Business Workarounds
Business owners with multiple entities face a choice: treat each entity separately for Section 199A purposes or aggregate them. Aggregation under Revenue Procedure 2019-11 pools W-2 wages and qualified property across entities, which helps when one entity has high QBI but low wages and another has the reverse. Separation works better when one entity is a specified service trade or business subject to additional limitations.
Certain service businesses including health, law, accounting, consulting, and financial services are classified as specified service trades or businesses under Section 199A, and the deduction phases out and is eventually eliminated for owners above the income threshold. AE Tax Advisors works with these owners to separate non-service components, such as product sales, equipment rental, or real estate, into standalone entities that qualify for the full deduction. The firm also optimizes taxable income through retirement plan contributions and other deductions to keep the owner within the phase-in range where possible. The firm has found that strategic separation of service and non-service activities can preserve $20,000 to $40,000 in annual QBI deductions that would otherwise be lost to the specified service limitation.
The Retirement Plan Multiplier
Retirement plan contributions reduce taxable income but do not reduce qualified business income for Section 199A purposes. This creates a double benefit: contributions lower the owner’s tax bracket without affecting the QBI deduction calculation. AE Tax Advisors coordinates retirement plan design with Section 199A optimization, ensuring clients capture the maximum deduction while sheltering additional income through tax-deferred vehicles.
For a business owner contributing $200,000 to a defined benefit plan, the contribution reduces taxable income by $200,000 and produces $74,000 to $100,000 in tax savings, while the QBI deduction remains unchanged because qualified business income is calculated before the retirement deduction. The combined effect of the retirement contribution and the QBI deduction can reduce the effective tax rate on business income by 15 to 20 percentage points.
What This Means for Business Owners Under the Permanent OBBBA Rules
With the Section 199A deduction now permanent, business owners can plan around it with confidence that the rules will not sunset. AE Tax Advisors views Section 199A optimization as a recurring annual planning requirement because changes in income, property acquisitions, employee hires, and entity structure all affect the result from year to year. The firm continues to help clients capture the full 20% deduction through coordinated planning across their entire business and investment portfolio.
