Who Can Claim The Qualified Business Income Deduction?

THE TAX CUTTERY® · From the practice of Paul D. Diaz, EA, MBA
Updated September 26, 2026 · Federal tax overview

Eligible owners of pass-through businesses may qualify for a deduction of up to 20% of qualified business income under Section 199A. It is not simply 20% of sales or every dollar shown on a Schedule K-1. Income, business type, and other limitations affect the calculation.

Identify The Income That Qualifies

Sole proprietorships, partnerships, and S corporations may generate qualifying income. Employee wages and C corporation income do not qualify as QBI. Certain owner compensation and investment items are also excluded from QBI.

Use The Rules For The Actual Return Year

The calculation can depend on taxable income, net capital gain, wages, qualified property, and whether the business is a specified service trade or business. For tax years beginning after 2025, additional active-business minimum-deduction provisions may apply. Use the current Form 8995 or 8995-A instructions rather than carrying last year’s thresholds forward.

Rental Activity Requires Its Own Analysis

A rental is not automatically a qualifying business for every tax purpose. Section 199A has its own rules and a rental real estate safe harbor. Failing that safe harbor does not necessarily end the inquiry; the activity may qualify under other applicable rules.
