Answer:
A) $80,000
Step-by-step explanation:
According to the Internal Revenue Service (IRS), the deduction would be claim as a lower value of 20% qualified business income plus 20% of real investment or 20% of taxable income less net capital gains
So, 20% qualified business income = $400,000 × 20% = $80,000
And, the 20% of taxable income = $500,000 × 20% = $100,000
So, the lower value would be $80,000
