By QBAI do you mean qualified basis after investment, or what? Section 199A refers to UBIA, which is unadjusted basis immediately after acquisition. Assuming that is what you mean, we have this in the regs.
UBIA is determined without regard to any adjustments described in section 1016(a)(2) or (3), to any adjustments for tax credits claimed by the individual or RPE (for example, under section 50(c)), ...
. So I think your answer is no.
It's kind of interesting, but not really relevant, to compare the language in section 50(c),
(c) Basis adjustment to investment credit property
(1) In general
For purposes of this subtitle, if a credit is determined under this subpart with respect to any property, the basis of such property shall be reduced by the amount of the credit so determined.
,
with that in section 25D(f),
(f) Basis adjustments
For purposes of this subtitle, if a credit is allowed under this section for any expenditure with respect to any property, the increase in the basis of such property which would (but for this subsection) result from such expenditure shall be reduced by the amount of the credit so allowed.
. The headings say "adjustment(s)", yet basis adjustments are determined under section 1016.
