Qualified Business Income Deduction Limit
Close-up on the New QBI Deduction’s Wage Limit
The Tax Cuts and Jobs Act (TCJA) provides a valuable new tax break to noncorporate owners of pass-through entities: a deduction for a portion of qualified business income (QBI). The deduction generally applies to income from sole proprietorships, partnerships, S corporations and, typically, limited liability companies (LLCs). It can equal as much as 20% of QBI. But once taxable income exceeds $315,000 for married couples filing jointly or $157,500 for other filers, a wage limit begins to phase in.
Full vs. Partial Phase-In
When the wage limit is fully phased in, at $415,000 for joint filers and $207,500 for other filers, the QBI deduction generally can’t exceed the greater of the owner’s share of:
50% of the amount of W-2 wages paid to employees during the tax year, or[spacer height=”20px”]
The sum of 25% of W-2 wages plus 2.5% of the cost of qualified business property (QBP).
When the wage limit applies but isn’t yet fully phased in, the amount of the limit is reduced and the final deduction is calculated as follows:
The difference between taxable income and the applicable threshold is divided by $100,000 for joint filers or $50,000 for other filers.[spacer height=”20px”]
The resulting percentage is multiplied by the difference between the gross deduction and the fully wage-limited deduction.[spacer height=”20px”]
The result is subtracted from the gross deduction to determine the final deduction.
