IRS Provides Methods for Calculating W-2 Wages for QBI Deduction Limitation

For certain taxpayers, the deduction for Qualified Business Income (QBI) is limited to the greater of:

(1) 50% of the W-2 wages paid by the business, or

(2) 25% of the W-2 wages paid by the business, plus 2.5% of the unadjusted basis of the business’s qualified property.

In a recent Revenue Procedure, the IRS provided three methods for calculating W-2 wages for purposes of this limitation. The first method (the unmodified box method) allows for a simplified calculation, while the second and third methods (the modified Box 1 method and the tracking wages method) provide greater accuracy. After computing W-2 wages under one of these methods, taxpayers must determine the extent to which the W-2 wages are properly able to be allocated to QBI. The Revenue Procedure, which applies to tax years ending after 12/31/17, also may be used in computing the required reduction of the QBI deduction for certain specified agricultural and horticultural cooperative patrons.
