QBI Deduction (§199A)

The Qualified Business Income deduction, created by Section 199A of the tax code, lets owners of pass-through businesses (sole proprietorships, single-member LLCs, partnerships, S-corps) deduct up to 20% of their net qualified business income from taxable income. Below an annual income threshold (directionally around $200,000 single / $400,000 married-filing-jointly at 2026 levels) almost everyone gets the full 20%; above it the deduction phases out or is limited, with tighter rules for certain service businesses. It reduces income tax only, not self-employment tax.
