Am I mistaken or did the final regulations sneak in the reduction of QBID for the deductions for 1/2 SE tax, self-employed health insurance premiums, and retirement plan contributions?
Page 198 of the Final Regulations.
"(vi) Other deductions. Generally, deductions attributable to a trade or business are taken into account for purposes of computing QBI to the extent that the requirements of section 199A and this section are otherwise satisfied. For purposes of section 199A only, deductions such as the deductible portion of the tax on self-employment income under section 164(f), the self-employed health insurance deduction under section 162(l), and the deduction for contributions to qualified retirement plans under section 404 are considered attributable to a trade or business to the extent that the individual’s gross income from the trade or business is taken into account in calculating the allowable deduction, on a proportionate basis to the gross income received from the trade or business."
