Example 1.

Married taxpayer Sam is a sole proprietor engaged in a specified service trade or business (which generally would not be entitled to the 20% deduction). However, Sam has modified taxable income of $360,100 on his joint tax return which includes $100,000 of QBI and W-2 wages of $50,000 and does not have any qualified property. (Assume Sam satisfies any other requirements for taking the deduction). Compute Sam's QBI deduction for 2022?
