Are you getting the full §199A deduction?
Section 199A lets pass-through business owners deduct up to 20% of qualified business income. But it phases out above certain income levels, disappears entirely for some service businesses, and for S-corp owners the W-2 salary directly determines how much you can claim. See exactly where you stand.
2026 estimates · Not tax advice
For S-corps: total business net income before your salary. For sole props: Schedule C net profit.
Threshold: $406,100 — income above this starts limiting the deduction.
Engineering, real estate, tech, product, trades, e-commerce — the W-2 wage limitation applies above the threshold, but there's no full phase-out.
Higher salary → lower QBI (less deduction base) but higher W-2 wages → higher W-2 limit. See sensitivity table below when above threshold.
