Pass-through owners can deduct up to 20% of qualified business income. Estimate yours.
Estimates your Section 199A qualified business income deduction, worth up to 20% of QBI subject to a taxable-income cap.
The QBI deduction lets many pass-through owners deduct up to 20% of their qualified business income from sole proprietorships, partnerships, and S corporations. The deduction is also capped at 20% of your taxable income before the deduction, minus net capital gains, so the tool compares both figures and applies the lower one. This can meaningfully reduce the effective tax rate on business profits.
For 2025 the income thresholds are 197,300 for single filers and 394,600 for joint filers, below which the deduction is generally the straightforward 20%. Above those levels, W-2 wage and qualified-property limits phase in, and specified service businesses such as law, health, and consulting may lose the deduction entirely. This estimate ignores those phase-ins and is not tax advice, so confirm your figure with a tax professional or Form 8995-A.
Owners of pass-through businesses, including sole proprietors, partnerships, S corporations, and many LLCs, generally qualify. C corporations do not, since they use the corporate rate instead.
These are fields like health, law, accounting, consulting, and financial services where the deduction phases out above the income thresholds. Below the thresholds they still qualify for the full deduction.
No, it applies the simple 20% rules and does not model the W-2 wage or qualified-property tests that apply above the thresholds. Use Form 8995-A or a tax professional for higher incomes.
