Scenario 2 (joint filer over the $315,000 threshold, but below the phase-in threshold of $415,000)
Henry and Wanda are married and intend to file jointly for tax year 2018. Henry is a partner in a real estate partnership. Henry’s share of the partnership’s QBI is $300,000, and his share of W-2 wages paid by the partnership is $40,000. The partnership holds no qualified property so Henry’s share of UBIA is $0. Wanda earns wages from an unrelated company. Henry and Wanda’s combined taxable income for 2018 is $375,000 (which is within the phase-in threshold of $415,000). Harry and Wanda have no capital gain or loss for tax year 2018.
Because Henry’s and Wanda’s taxable income is above the threshold amount, their section 199A deduction is subject to additional limitations but, because they are within the phase-in range, the limitations will be phasedin. Because the partnership holds no qualified property, only the W-2 wage limitation applies. In order to apply the W-2 wage limitation, Henry and Wanda must first determine 20 percent of Henry’s share of the partnership’s QBI. 20 percent of Henry’s share of the partnership’s QBI is $60,000 ($300,000 x 20%). Next, Henry and Wanda must determine 50 percent of Henry’s share of the partnership’s W-2 wages. 50 percent of Henry’s share of the partnership’s W-2 wages is $20,000 ($40,000 x 50%). Because 50 percent of Henry’s share of the partnership’s W-2 wages is less than 20 percent of Henry’s share of the partnership’s QBI, Henry and Wanda must determine the QBI component of their section 199A deduction by reducing 20 percent of Henry’s share of the partnership’s QBI by the reduction amount.
Henry and Wanda are 60 percent through the phase-in range (that is, their taxable income exceeds the threshold amount by $60,000, and their phase-in range is $100,000). The excess amount is $40,000 (20 percent of Henry’s share of the partnership’s QBI, or $60,000, less 50 percent of Henry’s share of the partnership’s W-2 wages, or $20,000). The reduction amount is equal to 60 percent of the excess amount, or $24,000. Thus, the QBI component of Henry’s and Wanda’s section 199A deduction is equal to $36,000, 20% of B’s $300,000 share of the partnership’s QBI (that is, $60,000), reduced by $24,000. Henry’s and Wanda’s section 199A deduction is equal to the lesser of 20% of the QBI from the business as limited ($36,000) or (ii) 20% of Henry and Wanda’s taxable income ($375,000 x 20% = $75,000). Therefore, their section 199A deduction is $36,000 ($60,000 reduced by $24,000) for 2018.
