Explanation of Solution

Qualified Business Income: Qualified Business Income is a deduction available to eligible tax payers. Sec 199 A offers 20% deduction on qualified business income and 20% of qualified real estate investment trust and qualified publicly traded partnership income.

Person B and Person M are subject to QBI deduction of $60,000. However, their taxable income exceeds the threshold for married taxpayer so; their QBI deduction is limited to $14,400.

Compute applicable percentage:

Applicable percentage=100%(QBI deduction×(Modified taxable incomeMaximum limit))$100,000=100%($60,000×($381,400$321,000))$100,000=40%

Compute the QBI deduction.

ParticularsAmount ($)
20% of qualified business income(a)$60,000
Applicable percentage (b)40%
QBI deduction (a/b)$24,000

Table (1)

2. Not more than the greater of:

ParticularsAmount ($)Amount ($)
50% of W-2 wages (1)  or 80,000
25% of W-2 wages  (2)4,000 
2.5% of the unadjusted basis of qualified property (3)04,000

Table (2)

Working Notes (1): Calculate 50% of W-2 wages.

50% of W-2 wages=((Total payment of W-2 wages)×50%×Applicable percentage)=$40,000×50%×40%=$8,000

(2) Calculate 25% of W-2 wages.

25% of W-2 wages=((Total payment of W-2 wages)×20%×Applicable percentage)=$40,000×25%×40%=$4,000

(3) Calculate the 2.5% of the unadjusted basis of qualified property.

(2.5% of the unadjustedbasis of qualified property)=((Total unadjusted basis ofproperty)×2.5%×Applicable percentage)=($0×2.5%×40%)=$0

Mr. B and Mrs. M’s modified taxable income exceeds the threshold limit of $321,400 but less than $421,000. The W-2 wages is the limiting factor where the general 20% QBI amount.

1. Determine the difference between the general 20% deduction amount and the W-2 wages/ capital investment amount.

ParticularsAmount($)
General 20% QBI deduction amount24,000
Less: The W-2 wages/ capital investment limit(8,000)
Excess$16,000

Table (3)

2. Determine the reduction ratio.

Reduction ratio=((Taxable income beforethe QBI deduction)Threshold amount)100,000=$375,000$315,000$100,000=60%

3. Determine reduction in the W-2 wages.

W-2 wages=(Excess×Reduction ratio)=$16,000×60%=$9,600

4. Determine final QBI amount.

ParticularsAmount($)
General 20% QBI deduction amount24,000
Less: The W-2 wages/ capital investment limit(9,600)
Final QBI amount$14,400

Table (4)

Final amount is less than 20% of their modified taxable income, so they will allow $14,400 deduction for qualified business income.
