When setting up a company, there are 2 input boxes relating to the QBI 199A deduction (we call it the passthrough deduction).
This assists in the calculation of the deduction, it does not change the company financials in any way.
For Payroll, enter the business qualified W-2 wages expected to be paid for the full year.
For Fixed Assets, enter the the depreciable property capitalized in the business financials. See Sec. 199A(b)(6) for more information.
