What is Qualified business income deduction?

A deduction of up to 20 percent of qualified business income from pass-through businesses, subject to income limits and industry restrictions.

Why it matters on your return

For many owners it is the largest deduction on the return. Above the income thresholds, specified service businesses lose it and others face wage and property limits, which is where entity and compensation planning come in.

Example

A consultant with $120,000 of net profit below the threshold deducts $24,000, reducing taxable income without spending anything.

Does my S corporation salary reduce the deduction?

Yes. Wages paid to the owner are not qualified business income, so a higher salary lowers the deduction while reducing self-employment tax. The two effects are balanced in the S corp analysis.
