S Corp QBI. How does it work

dnmalkin — Wed, 11 Feb 2026 06:05:10 GMT

First year as an S Corp

Only one Shareholder, it is the owner of 100% stock:

K1 has Box 17 of code V, see stmt.

Statement (QBI or qualified PTP items subject to shareholder-specific determinations:) shows:

Ordinary Business Income: 48338

Section 179 Deduction: 8183

W2 wages: 33095

UBIA of qualified property: 8183

Based on this, What is the QBI?

I don't see the 20% deduction anywhere on 1120s. Does it somehow pass through to individual 1040? If so, where?

The deduction is not on the 1120S. it's only at the shareholder level that it's computed. the amount is transferred from the tax form to line\r 13 of page 1 of the 1040

In your 1040 look for form 8995. there are many factors that determine the QBI deduction besides the S_corp's net income. it can be affected by filing status, taxable income, whether the business is a Specified Service Trade or Business.

besides entering the 17V info make sure you complete the QBI section for the s-corp in Turbotax. turbotax dios not use that 17V info. (why?- don't know)
