QBI Deduction Formula 2026
Base Deduction: 20% of Qualified Business Income (QBI). For most taxpayers below the threshold, this is the full deduction.
Wage/Capital Limit (above thresholds): Deduction limited to the greater of: 50% of W-2 wages OR 25% of W-2 wages + 2.5% of UBIA.
SSTB (Specified Service Trade or Business): Complete phase-out above $245k (single) or $490k (MFJ). Includes health, law, accounting, consulting, financial services, athletics, performing arts.
Overall Limitation: QBI deduction cannot exceed 20% of taxable income (excluding capital gains).
Example: $100,000 W-2 wages, $500,000 UBIA. Wage limit = $100,000 × 50% = $50,000. Wage + Capital = ($100,000 × 25%) + ($500,000 × 2.5%) = $37,500. Greater = $50,000. Businesses with no employees face significant limitations above threshold.
How to Maximize Your QBI Deduction
Contribute to retirement plans (Solo 401k, SEP IRA) to reduce taxable income. For SSTB owners near phase-out, consider income deferral. Increase W-2 wages to boost wage limit. Invest in qualified property for UBIA. Consider aggregation election for multiple businesses. File jointly if spouse has W-2 income to increase MFJ threshold.
